Patent Description:
A suspended transport system is known, which comprises a running track and a vehicle in the form of a body. Running track is made in the form of two-rail track positioned on longitudinal beams installed on inner brackets (cantilevers) of intermediate supports. The system is equipped with a driving unit in the form of a running carriage with an electric motor installed thereon and a body on a pneumatic stabilizer [<NUM>].

The disadvantage of this transport system is the increased material intensity of its design, due to the very limited load-bearing capacity of the track beams, as well as the difficulty in transporting long span structures to the installation site, the difficulty of installing them in the field with a difficult landscape and the limited possibilities of using them to bridge large spans between neighboring intermediate supports.

There is also known a guiding track comprising two bearing elements and one longitudinal element connected by transverse elements, equipped with side sheets connecting the bearing elements to the longitudinal element, which is also made in the form of sheet, wherein one part of the transverse elements can be connected to the bearing elements, and the other part - to the longitudinal and bearing elements [<NUM>].

The disadvantage of this technical solution is that the known transport system has a bulky metal-intensive structure of a rail track structure, which requires very small spans between the intermediate supports of the overpass to ensure its reliability. Increasing the span between the supports, despite the structural rigidity of the rails of such a profile, leads (provided that reliability is maintained) to an excessive increase in material intensity of the rail track structure and a decrease in its specific carrying capacity. At the same time, the conditions for the delivery and installation of structural elements to the job site (installation site) are significantly complicated.

A transport system consisting of a bearing monorail and a transport module is known, wherein the bearing monorail is uniformly supported through modules - tetrahedra on piles - sleepers in the ground and has starting slides and finishing anti-slopes; whereas its transport module is a platform with two cabs on four central two-flanged wheels and four side supporting rollers, with self-centering flywheels - gyroscopes, with the possibility of installing a body - a cabin, tank, container, onboard platform, platform with racks for transportation of various goods. Or, in another embodiment of such a transport system, which consists of a suspended monorail and a transport module, wherein the suspended monorail is an I-beam suspended by braces along the edges of the modules - tetrahedra to two longitudinal load-bearing ropes tightened by transverse ties and also has starting slides and finishing anti-slopes. In this variant, the transport module is made suspended [<NUM>].

The disadvantages of such technical approach are that the mentioned transport system possesses low specific carrying capacity. As it is understood as the ratio of the payload weight to the deadweight of its track structure, which, in this case, leads to a significant increase in the cost of such transport system, it also means facing obstacles in delivery to the installation site and during assembling in field conditions of components of the track structure and limited possibilities of using the track of the specified structure to bridge large spans between adjacent intermediate supports.

A common drawback of the known transport systems is the low specific carrying capacity of their track structures, leading to a significant increase in the cost of the entire transport system, which, as a rule, provides for the design of a track structure in the form of heavy and bulky beams of long span structures, the delivery and installation of which in real field conditions with a complex landscape is a very difficult and costly technology.

Furthermore, the presence of joints in the rail track and temperature deformation of the rails of such transport systems do not allow to achieve "velvetsmooth" path for the vehicle, which means that it is impossible to achieve high speed and ensure high reliability of transportation on track structures of that type.

Further development of the structures of transport systems of the suspension and overpass types was gained with the development and creation of a transport system based on the string track structure by Yunitski, which is based on the use as the main structural elements of the rail with its prestressed in the longitudinal direction load-bearing string - rod components.

The transport system by Yunitski is known, which includes at least one track structure tensioned above the foundation in span between the supports in the form of a load-bearing element encased in a body with a rolling surface for movement of wheeled vehicles (movable transportation means) installed on the track structure [<NUM>]. In the abovementioned installation, cross-sectional areas of the load-bearing element and the rail body with rolling surface are optimized, as well as - tensile force of the track structure and the load-bearing element of this structure, calculation of sag height of the track structure between adjacent supports and height of supports are justified.

However, the known transport system has excessive material intensity and, therefore, increased cost, as well as low technological effectiveness and, as a result, high labor input.

A string transport system by Yunitski is also known, which includes at least one, tensioned above the foundation in a span between anchor supports, rail cord in the form of a load-bearing element encased in body with a rolling surface for self-powered movable units. Hereby, the load-bearing elements of the load-bearing member are connected to each other and to the body in a monolith (throughout the volume) by means of filler. On the supports there are transitional portions of the track, and the rail cord in the span between the supports is made with sagging deflection of a certain slope, while the transition section of the track on the support is made with the same slope as the section of the suspended portion of the track that conjugates therewith in the span between the supports [<NUM>].

That track structure has increased material and labor intensity, and, therefore, increased cost and penalized technicality.

Among transport systems with a rail track structure related to suspended and overpass roads, Yunitski transport system rail is known, which contains a tubular hollow body with overlay head, inside which there is a load-bearing member made of prestressed load-bearing elements, mainly wires and/or ropes distributed along the cross profile of the rail, and the walls of the body are closed. Various variants of distribution of ropes along rail section and optimal ratio of cross-sectional areas of rail body and ropes are possible. Hereby, the body is made in the form of a spiral enclosing the load-bearing member, and the overlay head is fixed on the spiral turns. The space between the body and the load-bearing member is filled with filler [<NUM>]. The method of producing such rail of the track structure by Yunitski consists in the fact that the load-bearing member is formed of load-bearing elements and used as a mandrel in the manufacture of the rail body, and when the rail body is being produced, the load-bearing member is placed therein by laying on the surface of the load-bearing member of ordinary winding made of high-strength wire or band.

Transport system with such rail cords ensures high manufacturability. However, the material intensity of said track structure obtained by the described method is still excessive.

Transport system by Yunitski [<NUM>], which is accepted as a prototype, appears to be the closest as regards the declared technical essence and achieved result. It includes at least one, tensioned above the foundation in spans between supports, rail cord in the form of a load-bearing member, containing load-bearing elements prestressed in longitudinal direction, concreted into the binder layer of the load-bearing member, and enclosed in a hollow body with a rolling surface for movement of wheeled self-powered movable units installed on the track structure.

In the abovementioned technical solution, the rail cord is equipped with a hollow body, which acts as a casing for the load-bearing member, hereby, the hollow body is provided with a rolling surface for wheeled self-powered movable units, and the load-bearing member placed in the hollow body is made in the form of load-bearing elements prestressed in longitudinal direction, which are cemented in the binder layer. The load-bearing member and the hollow body wherein it is placed are joined through the binder layer.

The transport system with a track structure of this type provides a high specific carrying capacity, but the material intensity and manufacturability of the rail cord design remain insufficiently optimized.

It is desirable to simplify the construction of the rail cord.

The aim of the present invention is to achieve the following technical objectives:.

The above result is also achieved thanks to the fact that, according to the second variant of the invention, in the transport system by Yunitski, which represents at least one rail cord tensioned above foundation in spans between supports, in form of a load-bearing member, comprising a pile of at least two longitudinally prestressed discrete load-bearing elements, concreted into binder layer of the load-bearing member, and conjugated therewith loaded layer with rolling surface for self-powered movable units, whereby the load-bearing member is made bodiless, and the loaded layer with the rolling surface is fastened directly on the binder layer of the load-bearing member, wherein the discrete load-bearing elements are concreted into the binder layer to depth h<NUM>, m, - from the rolling surface, and a depth h<NUM>, m, - to its opposite face, defined by the ratios: <MAT> <MAT> where S<NUM>, m - the height of the discrete load-bearing element in the pile of the load-bearing member,.

The above result is also achieved thanks to the fact that, according to the third variant of the invention, in the transport system by Yunitski, which represents at least one rail cord tensioned over foundation in spans between supports, in form of a load-bearing member, comprising longitudinally prestressed load-bearing elements, concreted into binder layer of the load-bearing member; and conjugated therewith loaded layer with rolling surface for self-powered movable units, wherein the load-bearing member is made bodiless, whereby the load-bearing member is made bodiless, whereas loaded layer with rolling surface is fastened directly on the binder layer of the load-bearing member; wherein the load-bearing member is made in the form of a (distributed along the height of the load-bearing member) combination of one or several isolated load-bearing elements and/or one or several piles of discrete load-bearing elements, concreted into the binder layer to depth h<NUM>, m, - from rolling surface and depth h<NUM>, m, - to its opposite face, defined by the ratios: <MAT> <MAT>
where S<NUM>, m - total height of isolated load-bearing elements and/or one or several piles of discrete load-bearing elements, including distance L, m, between them in the load-bearing member,.

Achieving the technical aim according to any of the three variants of the present invention is also secured thanks to the fact that the binder layer of the load-bearing member can be made of hardening material based on polymer binder composites.

Successfully tackling the technical object according to any of the three variants of the present invention is also secured thanks to the fact that polyetheretherketone (PEEK), or polyurethane, or polyurea, or a combination thereof, are used as polymer binder composite.

Attaining the technical aim according to any of the three variants of the present invention is also secured thanks to the fact that cross profile of the load-bearing elements is made in the form of a disc, and/or an ellipse, and/or a square, and/or a rectangle, and/or a rhombus, and/or a triangle, and/or a trapezoid, and/or a polygon.

Successfully achieving the technical object according to any of the three variants of the present invention is also secured thanks to the fact that the load-bearing elements are made in the form of wire, and/or twisted or non-twisted ropes, cables, and/or strands, and/or cords, and/or rods, and/or strips, and/or bands, and/or tubes.

According to any of the three abovementioned variants of the proposed technical approach, the design of the rail cord helps to increase both the specific carrying capacity of the track structure and the processability of the production process of the transport system as a whole.

The essence of the present invention is illustrated by the drawings, <FIG>, exhibiting the following:.

The proposed transport system (see <FIG>) represents at least one rail cord <NUM> tensioned above foundation <NUM> in spans <NUM> between supports <NUM>, in form of load-bearing member <NUM>, comprising at least one (see <FIG>) longitudinally prestressed isolated load-bearing element.

Depending on design option, load-bearing elements may be embodied as isolated <NUM>, as shown on <FIG> and <FIG>, or discrete <NUM>, aggregated in pile <NUM> (see <FIG> and <FIG>) and positioned in line on one level as shown on <FIG>. <FIG> show the embodiment of load-bearing member <NUM> in the form of combination of one or several isolated <NUM> load-bearing elements and/or one or several piles of <NUM> discrete <NUM> load-bearing elements.

Hereby, rail cord <NUM> contains load-bearing elements (<NUM> and/or <NUM>) concreted into binder <NUM> layer of load-bearing member <NUM> and loaded <NUM> layer conjugated with the binder <NUM> layer with rolling surface K for self-powered movable units <NUM>.

Depending on the properties of foundation <NUM>, place of installation and the set of functions, supports <NUM> can have various design designs - in the form of towers, columns with heads, steel and reinforced concrete columnar and frame buildings and structures equipped with passenger stations and/or cargo terminals, other functional structures or truss structures. The design of supports <NUM> may vary depending on where they are installed. In particular, the shape of heads (not shown on Figures) with devices for fastening load-bearing member <NUM> installed on the turns of the track, on linear sections of the track, in the mountains or at the terminal ends of the track, can be different, since the abovementioned devices must be smoothly coupled with the suspended sections of rail cord <NUM> in spans <NUM> between supports <NUM>. Furthermore, the shape of heads can be determined by the fact whether they are the location of passenger stations and/or cargo terminals, interchange / junction nodes (turn-out switches and turn sections) of the transport system. Supports <NUM> can be combined with buildings and construction facilities (not shown on figures).

Self-powered movable units <NUM> (passenger and/or freight and/or cargo passenger), which are part of the transport system, can be embodied as in suspended design (in suspended position and fastened from below to rail cord <NUM> of transport system on wheels of movable unit <NUM>), as shown on <FIG>, or in mounted design (mounted by wheels of movable unit <NUM> on rail cord <NUM>, not shown on Figures).

In accordance with any of the non-limiting variants of practical implementation of the proposed transport system, one of its main elements determining the essence of the proposed technical approach is the rail cord <NUM> of the track structure. The principal feature of the rail cord <NUM> according to the proposed technical approach is that it is made in the form of load-bearing member <NUM> containing at least one load-bearing element (<NUM> and/or <NUM>), prestressed in the longitudinal direction, concreted into the binder <NUM> layer of this load-bearing member <NUM>, and the therewith conjugated loaded <NUM> layer with rolling surface K for self-powered movable units <NUM> (see <FIG>), and not comprising an additional body wherein this load-bearing member <NUM> would be located.

In this case, it is essential that load-bearing member <NUM> is body-free, and loaded <NUM> layer with rolling surface K merges with binder <NUM> layer of load-bearing member <NUM> and is monolithically coupled with it.

With such design, load-bearing member <NUM> with therewith conjugated rolling surface K does not have an additional case shell in the form of a body, which is present in the prototype and analogues.

Implementation in the proposed transport system of the track structure of innovative modification - with a rail cord <NUM> in the form of load-bearing member <NUM>, which does not have body in the form of a shell, allows, due to decrease in mass and cross-sectional area of rail cord <NUM>, to achieve significant advantages compared to the known technical solutions. In particular, the task is to ensure increase in the specific carrying capacity of the track structure with decrease in material capacity and labor intensity and processability of its manufacture, for example, thanks to deliveries to the installation site of rail cord <NUM> of the proposed track structure of blanks of various types of load-bearing elements in the form of bundles and/or rolls.

According to any of the three variants of embodiment of the present invention, as load-bearing elements of load-bearing member <NUM> of rail cord <NUM>, cross-section of which is schematically shown on <FIG>, longitudinally prestressed load-bearing elements in the form of wire, and/or twisted or non-twisted ropes, and/or strands, and/or cords, and/or rods, and/or strips, and/or bands, and/or tubes, may be used, made of any durable materials, such as fiberglass, or steel, to ensure reliability, efficiency, cost-effectiveness and processability of such load-bearing elements.

Load-bearing elements, prestressed in longitudinal direction, are concreted into binder <NUM> layer, and form load-bearing member <NUM> of rail cord <NUM> with loaded <NUM> layer conjugated therewith, with rolling surface K for self-powered movable units <NUM>.

Moreover, in accordance with any of the non-limiting variants of practical implementation, according to any of the three embodiments of the transport system, it is advisable to use a hardening material as materials of binder <NUM> and loaded <NUM> layers, for example, in the form of a composition based on polymer binder composites, and/or a similar hardening material that rigidly binds / concretes prestressed in the longitudinal direction corresponding load-bearing elements into a single whole.

Depending on the design option, according to any of the three embodiments of the present invention, polyetheretherketone (PEEK) is the most preferred hardening material for such use. However, polyurea and/or polyurethane and/or a combination thereof can be used as the hardening material. The use of the above materials will ensure high technological effectiveness of the track structure and the transport system as a whole, while ensuring high design wear resistance, strength and durability, as well as increased hardness with low friction coefficient on the rolling surface K of the rail cord <NUM> of the track structure.

One alternative embodiment of the hardening material is its practical implementation with a closed cell structure, which increases the specific bearing capacity of rail cord <NUM> of track structure.

As a result of implementation of the proposed technical solution, according to any of the three embodiments of the proposed invention, in accordance with the set of all essential features defining it, the formation of the track structure of the transport system is achieved in the form of monolithic load-bearing member <NUM> of rail cord <NUM> and rolling surface K conjugated with them for self-powered movable units <NUM>, which provides accommodation, transfer and redistribution of high contact stresses to all prestressed in the longitudinal direction corresponding load-bearing elements of load-bearing member <NUM>, which significantly increases strength and flexural rigidity of the track structure, with significant decrease in materials intensity.

In order to optimize the performance of the rail cord <NUM>, it is advisable that, according to any of the three embodiments of the present invention, cross profile of the load-bearing elements is made in the form of a disc, and/or an ellipse, and/or a square, and/or a rectangle, and/or a rhombus, and/or a triangle, and/or a trapezoid, and/or a polygon.

The claimed transport system, according to the first embodiment, is characterized by that isolated <NUM> load-bearing element of load-bearing member <NUM> is made concreted into binder <NUM> layer (see <FIG> and <FIG>).

Hereby, according to the first embodiment, the width <NUM>, m, of isolated <NUM> load-bearing element is defined by the dependence: <MAT>.

If the ratio (<NUM>) is less than <NUM>, then the required rigidity of the load-bearing member <NUM> in the transverse direction is not guaranteed, which leads to increased wear of the rail cord <NUM> and penalized efficiency of the transport system.

If the ratio (<NUM>) is more than <NUM>, it becomes problematic to ensure the integrity of the load-bearing member <NUM> during operation of the transport system and the probability of splitting it into fragments increases: isolated <NUM> load-bearing element with loaded <NUM> layer and binder <NUM> layer of load-bearing member <NUM>, which loses connection with them from below (from the face of the load-bearing member <NUM> opposite to the rolling surface K).

Depending on the design option, a possible variant of practical implementation of the proposed transport system according to the first embodiment of the invention is a rail cord <NUM> with isolated <NUM> load-bearing element, for example in the form of a band, which is shown on <FIG>.

An alternative variant of practical implementation of the proposed transport system, according to the first embodiment of the invention, is the embodiment of the rail cord <NUM> with isolated <NUM> load-bearing element of elliptical section, which is shown on <FIG>.

According to any of the first two embodiments of the invention, the load-bearing elements (in the form of isolated <NUM>, or pile <NUM> of discrete <NUM>) are concreted into binder <NUM> layer to the depth h<NUM>, m, - from the rolling surface, and to the depth h<NUM>, m, - to its opposite face, defined by the ratios: <MAT> <MAT> <MAT> <MAT>.

When the wheels of self-powered movable unit <NUM> move along rail cord <NUM>, rolling surface K experiences pressure concentrated on a small area, leading to its deformation.

When the load-bearing elements (isolated <NUM>, or pile <NUM> of discrete <NUM>) are concreted in the binder <NUM> layer to the depth values indicated in the ratios (<NUM>) - (<NUM>), the rail cord <NUM> operates under the wheels of the self-powered movable unit <NUM> as a rigid continuous beam. Hereby, it is possible to simply ensure the transformation of large local pressures from the wheels of the self-powered movable unit <NUM> on the rolling surface K into the range of permissible stresses of load-bearing elements (isolated <NUM>, or pile <NUM> of discrete <NUM>), and the rail cord <NUM> as a whole.

If the ratios (<NUM>) and (<NUM>) are less than <NUM>, the loaded <NUM> layer does not fully provide the function of the transfer element to evenly redistribute the pressures of local deformation waves moving along the rolling surface K under the influence of the load from the self-powered movable unit <NUM> to the load-bearing elements (isolated <NUM> element, or to the pile <NUM> of discrete <NUM> elements). Accordingly, when the values specified in the ratios (<NUM>) and (<NUM>) decrease below <NUM>, the possibility of the effect of unacceptable local pressures on the rail cord <NUM> is not excluded.

If the ratios (<NUM>) and (<NUM>) are more than <NUM>, then the rail cord <NUM> will have insufficient hardness and hardness of the rolling surface K.

If the ratios (<NUM>) and (<NUM>) are less than <NUM>, then the binder <NUM> layer does not fully provide a reliable connection between the elements of the load-bearing member <NUM>, required to maintain the integrity of the rail cord <NUM> and ensure monolithic concreting of the load-bearing elements (isolated <NUM>, or pile <NUM> of discrete <NUM>) of the load-bearing member <NUM> from below.

If the ratios (<NUM>) and (<NUM>) are more than <NUM>, then there occurs an unjustified increase in the thickness of the load-bearing member <NUM> below the rail cord <NUM> and an over-consumption of the material of the binder <NUM> layer.

According to any of the three embodiments of the invention, dimensions of load-bearing member <NUM> are selected so that inequality for the ratio of width A, m, of load-bearing member <NUM>, to its height H, m, is within limits: <MAT>.

If the ratio (<NUM>) is less than <NUM>, the rail cord <NUM> of the proposed transport system will have low specific bearing capacity and strength.

If the ratio (<NUM>) is more than <NUM>, then the rail cord <NUM> will have insufficient rigidity, including torsional, when being driven along by self-powered movable unit <NUM>.

It will be appreciated by a specialist skilled in the art that the present inventive concept allows for the use, according to the first embodiment of the invention, of a plurality of design-driven combinations of cross-sectional types of isolated load-bearing element <NUM> used in the formation of the load-bearing member <NUM> of the rail cord <NUM>.

The proposed transport system, according to the second embodiment of the invention, is characterized by that the load-bearing member <NUM> comprises a pile <NUM> of at least two prestressed in the longitudinal direction and concreted by the binder <NUM> layer discrete <NUM> load-bearing elements, of width d, m, of each of such load-bearing elements located, as shown on <FIG>, at one level in line - a straight line, or a curve (not shown on the drawings).

According to the practical implementation of the proposed technical solution according to the second embodiment of the invention, it is characteristic to make load-bearing member <NUM> in the form of a pile <NUM> of at least two discrete <NUM> load-bearing elements with the width d, m, of each of them. In this case, the gap δ, m, between adjacent discrete <NUM> load-bearing elements is determined by the dependence: <MAT>.

If the ratio (<NUM>) is more than <NUM>, then the considerable thickness of the binder <NUM> layer in the gap δ, m, between adjacent discrete load-bearing elements <NUM> will not provide the rail cord <NUM> with the required rigidity and bearing capacity.

The ratio (<NUM>) cannot be less than <NUM>, since the gap cannot be negative (see <FIG>).

According to the second embodiment of the invention, the total width B<NUM>, m, of the pile <NUM> of prestressed in longitudinal direction discrete <NUM> load-bearing elements of load-bearing member <NUM>, including gaps δ, m, therebetween (see <FIG>), is defined by the dependence: <MAT>.

If the ratio (<NUM>) is less than <NUM>, then the required rigidity in the transverse direction of the load-bearing member <NUM>, made in the form of pile <NUM> of (at least two) discrete <NUM> load-bearing elements positioned in line, is not ensured, which leads to increased wear of the rail cord <NUM> and penalized efficiency of the transport system.

If the ratio (<NUM>) is more than <NUM>, it becomes problematic to ensure the integrity of the load-bearing member <NUM> during operation, with increased probability for it to be splitting into fragments:.

Alternative, according to the second embodiment of the invention, is an embodiment of rail cord <NUM> with discrete <NUM> load-bearing elements in the form of cables or ropes, with the width d, m, of each of the load-bearing elements, piled up as shown on <FIG>.

On <FIG>, <FIG> and <FIG>, according to the second embodiment of the invention, show possible alternatives to the design of the rail cord <NUM> with piles of <NUM> discrete <NUM> load-bearing elements having, respectively, round and triangular sections and made of width d, m, of each of the load-bearing elements. When selecting discrete <NUM> load-bearing elements of triangular cross-section, it is advisable to install them in binder <NUM> layer with parallel arrangement of adjacent faces.

Embodiments of the rail cord <NUM> with piles <NUM> of discrete <NUM> load-bearing elements with sections in the form of a square, or polygon, or other possible of.

the known forms, are similar to those presented above and are not shown on the figures.

The proposed transport system, according to the third embodiment of the invention, is characterized by that the load-bearing member <NUM> is made in the form of, distributed (at least in two levels) along the height of the load-bearing member <NUM>, combination of one or several isolated <NUM> load-bearing elements and/or one or several piles <NUM> of discrete <NUM> load-bearing elements concreted by the binder <NUM> layer (see <FIG>).

According to the third embodiment of the invention, the load-bearing member <NUM> is made combined from one or several isolated <NUM> load-bearing elements and/or one or several piles <NUM> of discrete <NUM> load-bearing elements concreted into the binder <NUM> layer to the depth h1, m, - from the rolling surface, and depth h2, m, - to its opposite face, defined from ratios: <MAT> <MAT> where S<NUM>, m - total height of isolated load-bearing elements and/or one or several piles of discrete load-bearing elements, including distance L, m, between them in load-bearing member <NUM>.

When such load-bearing member <NUM> is concreted into the binder <NUM> layer to the depth indicated in the ratios (<NUM>) and (<NUM>), this load-bearing member <NUM> operates under the wheels of self-powered movable unit <NUM> as a rigid continuous beam.

If the ratio (<NUM>) is less than <NUM>, the loaded <NUM> layer does not fully provide a function of the transfer element for uniform redistribution of pressures of local deformation waves moving along the rolling surface K under the influence of the load from the self-powered movable unit <NUM>, to the corresponding load-bearing elements. If the value specified in the ratio (<NUM>) decreases below <NUM>, the possibility of the effect of unacceptable local pressures on the load-bearing elements forming the combined load-bearing member <NUM> of the rail cord <NUM> is not excluded.

If the ratio (<NUM>) is more than <NUM>, then such load-bearing member <NUM> will have insufficient hardness and rigidity of the rolling surface K of the rail cord <NUM>.

If the ratio (<NUM>) is less than <NUM>, then the binder <NUM> layer does not fully provide the monolithic concreting of the load-bearing member <NUM> from below and the reliable connection between the load-bearing elements included therein, necessary to maintain the integrity of the rail cord <NUM>.

If the ratio (<NUM>) is more than <NUM>, then there occurs an unjustified increase in the thickness of the load-bearing member <NUM> at the bottom of the rail cord <NUM> and an overspending of the material of binder <NUM> layer.

According to the third embodiment of the invention, distance L, m, between levels of adjacent isolated <NUM> load-bearing elements shall not exceed the lowest height Smin , m, of load-bearing elements included in combined load-bearing member <NUM>. Otherwise, the stiffness of such load-bearing member <NUM> and rail cord <NUM> is penalized, which is unacceptable.

According to the third embodiment of the invention, by adhering to the above specified range of the distance L, m, between adjacent levels of the load-bearing elements (isolated <NUM> and/or in the form of pile <NUM> of discrete <NUM> load-bearing elements), the bearing capacity of the rail cord is increased.

On <FIG>, examples of cross sections of the rail cord <NUM> in various alternative embodiments of the combined load-bearing member <NUM> are given. The above mentioned figures show alternative variants of the load-bearing member <NUM>, wherein its constituent load-bearing elements are arranged in two and three levels with different combinations of the shape of the used load-bearing elements.

It will be appreciated by a specialist skilled in the art that the present idea of the invention allows for the use, according to any of the three embodiments of the invention, of a plurality of design-specific combinations of the cross-sectional shapes of the load-bearing member <NUM> of the rail cord <NUM> depending on the shape and combination of the load-bearing elements contained therein.

According to any of the three embodiments of the invention, with any variants of practical implementation and arrangement of load-bearing elements of the load-bearing member <NUM> as a whole, in accordance with the proposed technical approach, the required material saving, improvement of processability and stability of the rail cord <NUM> throughout the transport system are achieved.

Taking into account all possible alternative and non-exclusive combinations, including the above-mentioned variants and parameters of implementation of load-bearing elements (<NUM> and <NUM>) and binder <NUM> layer of load-bearing member <NUM> of the rail cord <NUM>, numerous examples of practical implementation of the claimed transport system are possible, which generally provide installation on foundation <NUM>, directly along the track profile of the route, of supports <NUM> with spans <NUM> in accordance with the design option (see <FIG>). At least one rail cord <NUM> tensioned above foundation <NUM> is fastened on supports <NUM>. At the same time, the rail cord <NUM> is made in the form of load-bearing member <NUM> with loaded <NUM> layer applied thereon and rolling surface K. The load-bearing member <NUM>, in turn, is made of one or several load-bearing elements (<NUM> and/or <NUM>) arranged in an appropriate manner and which are made prestressed in the longitudinal direction by tensioning and fastening them between the supports <NUM>, and coating with a corresponding binder <NUM> layer. Suitably, in order to increase the processability, efficiency and manufacturability of the process of forming the track structure of the proposed transport system, the process of forming the load-bearing member <NUM> of the rail cord <NUM> is carried out by a special automatic mounting complex (not shown on figures), simulating, in the course of its operation, the weight load created by the self-powered movable unit <NUM> and performing continuous application, in accordance with the design option, of binder <NUM> and loaded <NUM> layers from hardening material, for example, in the form of a composition based on polymer binder composites, for example, polyetheretherketone (PEEK), and/or polyurea, and/or polyurethane, and/or combinations thereof. At the same time, the load-bearing elements are made concreted at a certain depth into the binder <NUM> layer of this load-bearing member <NUM> and conjugated therewith loaded <NUM> (by self-powered movable unit <NUM>) layer with rolling surface K.

It is essential that the load-bearing member <NUM> is made bodiless due to hardening of the binder <NUM> and loaded <NUM> layers, the last of which is equipped with rolling surface K.

According to the present technical approach, the required result is achieved by reducing the material consumption of the proposed rail cord <NUM> as compared to the known technical solutions. At the same time, the implementation of the rail cord <NUM> with the design proposed in this technical approach, provides the required strength of the track structure, since the main accommodation of the power load by the rail cord <NUM> from the movable units <NUM> is carried out by its load-bearing member <NUM>. In addition, it becomes possible to assemble the rail cord <NUM> in field conditions using high-tech equipment delivered directly to the installation site of the transport system. Hereby, component materials (for example, wire, or band / tape) can be delivered to the installation site of the transport system in a compact form - in the form of rolls, which contributes to decrease in materials intensity, labor, transportation costs, the cost of manufacturing and installation of the track structure while improving the processability of manufacturing of such transport system.

Optimized as a result of empirical studies, the geometrical parameters of load-bearing member <NUM> and the characteristics of binder <NUM> layer and load-bearing elements (<NUM> and/or <NUM>) forming it, for various embodiments of the proposed transport system make it possible to create rail cord <NUM> of the transport system with given operational parameters and ensure increase in the specific carrying capacity of the track structure.

The proposed transport system can be implemented in field conditions at a lower cost relative to the known designs of track structures and is high-tech.

The process diagram presented above in a simplified form illustrates one of the possible variants of production of the transport system according to the proposed technical approach.

The transport system of the described structure works as follows When the wheels of the self-powered movable unit <NUM> move along the rail cord <NUM>, the latter, with its rolling surface K, experiences and accommodates pressure concentrated on a small area, leading to its deformation. The deformation wave moving together with the wheels of the self-powered movable unit <NUM>, through a hardening material, for example, polyetheretherketone (PEEK), and/or polyurea, and/or polyurethane, of loaded <NUM> and binder <NUM> layers of load-bearing member <NUM>, is transmitted to load-bearing element stretched on supports <NUM>. At the same time, load-bearing member <NUM> does not work as a flexible rope, but as a rigid continuous beam.

Thanks to such transformation of substantial local pressures from the wheels of a self-powered movable unit <NUM>, the structural components of load-bearing member <NUM> of rail cord <NUM> do not experience prohibitively high pressures and, therefore, the carrying capacity of the track structure of the transport system by remains unchanged over time.

Claim 1:

and the width B<NUM>, m, of the isolated load-bearing element (<NUM>) is defined by the dependence: <MAT>
