A first implementation of the present application provides a water replacement type storage field construction method, as shown inFIGS.1-5, including the following steps:

(1) Construction of a Water-Stop Enclosure:

In one implementation, as shown inFIG.2, a plurality of cylindrical structures101may be inserted in the water to reinforce the enclosure foundation and also act as water stop and enclosure structures to form a water-stop enclosure1. Specifically, each cylindrical structure101includes a cylindrical steel plate1011and auxiliary steel plates1012, as shown inFIGS.1and2.

Firstly, each cylindrical steel plate1011is inserted into a soft soil foundation to enhance the shear strength of the soil foundation. The construction of inserting the cylindrical steel plates1011into the soft soil foundation may be completed by a process of hoisting a vibration hammer set using a crane ship to vibrate and sink.

Then, two auxiliary steel plates1012are inserted into the soft soil foundation between every two adjacent cylindrical steel plates1011along the mortise grooves (which are not shown and may be mortises in the prior art) on outer walls of the adjacent cylindrical steel plates1011to close the gap between the adjacent cylindrical steel plates1011. Sealing material is applied at the junctions of the auxiliary steel plates1012and the mortise grooves to realize water tightness.

The auxiliary steel plates1012may also be inserted into the soft soil foundation by the process of hoisting a vibration hammer set using a crane ship to vibrate and sink. The sealing material may be a mixture of sawdust, asphalt or other materials, and is placed in the mortise grooves in advance so as to keep watertightness in the process of inserting the auxiliary steel plates1012into the mortise grooves. Or, the sealing material may also be cement paste, and is injected into the mortise grooves through preset pipes after the auxiliary steel plates1012are inserted into the mortise grooves, so as to realize water tightness.

Then, the interior of each cylindrical steel plate1011and the inner cavity1013formed between every two opposite auxiliary steel plates1012are back-filled to form the water-stop enclosure1.

Sand and gravel may be used for the back-filling, and may be carried out on the water by using a belt ship, or may be carried by using a land device, so that the water-stop enclosure1keeps the shape of each cylindrical steel plate from shrinking by means of the silo pressure of the sand and gravel. The cylindrical steel plates are kept from buckling and breaking by means of the strength of the sand and gravel and the cylindrical structures101, and the water-stop enclosure1is kept from toppling and slipping by means of the gravity of the sand and gravel, the gravity of the cylindrical structures101and the frictional resistance of the buried part, thereby overall stability is maintained. The top of the water-stop enclosure1may also be leveled and compacted to form a construction road for the construction and passage of construction machines and vehicles.

(2) Construction of Drainage after Enclosing

After the water-stop enclosure1is enclosed, water in the enclosed range is drained to expose a pit2so as to form dry construction condition. The pit2may be leveled according to the actual conditions for further construction of a stacking yard3inside the water-stop enclosure1. The leveling is to level the pit completely or partially, excluding filling in the conventional sense. The main purpose of filling is for elevation, and the material consumption thereof will be significantly higher than that of the leveling.

(3) Construction of Riprap Mounds4

As shown inFIG.4, riprap mounds4may be constructed at the inner and outer sides of the water-stop enclosure1, respectively. The riprap mounds4roughly form a right-angled trapezoid shape fitted with the water-stop enclosure1at the inner and outer sides respectively, and the upper surfaces of the riprap mounds4are roughly flush with the upper surface of the water-stop enclosure1.

The parts of the riprap mounds4below the water surface may be dump-filled on the water by using a riprap ship, or may be partially dump-filled by using a land device and the left dump-filled on the water by using a riprap ship; and, the parts of the riprap mounds4above the water surface may be dump-filled by using a land device. The riprap mounds102at the inner side of the water-stop enclosure may be all filled by using a land device.

As shown inFIGS.6-8, a wave wall5extending upward may be constructed in an upper portion of the water-stop enclosure1or in upper portions of the riprap mounds4at the outer side, so as to reduce the amount of wave entering the water-stop enclosure1. The wave wall5may be formed by casting reinforced concrete.

(4) Construction of a Stacking Yard3

After the dry construction condition is formed, the construction of the stacking yard3is carried out, including constructing a low-level terrace6and a high-level terrace7; wherein, the low-level terrace6is lower than the average water level at the outer side of the water-stop enclosure1, and may be 3 m to 20 mm lower than the average water level according to the actual water depth and the construction environment so as to form the material stacking condition. Or, as shown inFIG.7, the average depth from the pit2to the top of the water-stop enclosure1is L1 and the depth from the surface of the low-level terrace6to the top of the water-stop enclosure1is L2, then 100%≥L2/L1≥50%, for example, L2/L1≥60%, L2/L1≥65%, L2/L1≥70%, L2/L1≥75%, L2/L1≥80%, etc. Since the surface of the low-level terrace6is below the water surface, a larger available space is formed thereabove. The high-level terrace7can be built based on the low-level terrace6, and has a larger height to form the conditions of mounting and running the stacking-reclaiming device9.

More specifically, as shown inFIGS.7and8, a water permeable cushion601, a water blocking cushion602, a waterproof layer603and a baseplate layer604are formed sequentially from bottom up in the drained pit2, so as to form the low-level terrace6. The water permeable cushion601can be formed by paving water permeable gravel in the pit2. Since water seepage may occur in the pit2, a buoyancy force will be produced to the low-level terrace6and may burst the low-level terrace6. By providing the water permeable cushion601, the pressure from water may be reduced or eliminated to protect other layers above the water permeable cushion from damage. Thus, the water permeable cushion601has the functions of filtration, decompression and drainage. The water blocking cushion602can be formed by casting cement or concrete on the water permeable cushion601. The water blocking cushion602can block water to a certain extent, which facilitates the subsequence construction of the waterproof layer603and becomes a joint layer of the water permeable cushion601and the waterproof layer603. The waterproof layer603can be formed by coating waterproof material or paving a physical waterproof layer (e.g., multilayer and partially laminated waterproof geotextile) on the water blocking cushion602, and plays a main waterproof function to prevent water seepage from entering the surface of the low-level terrace6. The baseplate layer604located on the waterproof layer603is conventionally formed by casting cement or concrete. As shown inFIG.8, the baseplate layer604is further provided with ground beams6041which are arranged at intervals and extend downward. The ground beams6041are plate structures and extend into the pit2, so that the bearing capability of the low-level terrace6is higher.

(5) Construction of Warehouses8

As shown inFIG.4, warehouses8including storage warehouses801and ballast warehouses802are arranged on the low-level terrace6, wherein the ballast warehouses802are evenly distributed nearby the storage warehouses801. The storage warehouses801are mainly used for storing materials (e.g., ore, coal, food, etc.), and the ballast warehouses802are mainly used for filling ballast (e.g., filling sand, stone, etc.) when the storage warehouses801are light. Considering that water seepage may occur on the bottom of the low-level terrace6(or the water blocking cushion602), when there are materials with proper weight in the storage warehouses801, a back pressure will be produced for the water seepage so as to overcome the buoyancy force of the water seepage. However, when there are few materials or no materials in the storage warehouses801, in order to prevent the buoyancy force produced by water seepage from damaging the low-level terrace6, ballasts may be filled in the ballast warehouses802to increase the back pressure of the low-level terrace6to the water seepage. It should be understood that the storage warehouses801and the ballast warehouses802may be mixed. For example, when there are many materials, the materials may be stored in both the storage warehouses and the ballast warehouses802, so that the ballast warehouses802function as storage warehouses801; and, when there are few materials, ballasts may also be filled in the storage warehouses801, so that the storage warehouses801function as ballast warehouses802.

The storage warehouses801and the ballast warehouses802may be arranged in regions, sections and layers, so that the space above the low-level terrace6is reasonably utilized. Since the low-level terrace6is located blow the average water level, the space provided above the low-level terrace is much larger than the space formed by a stacking yard obtained by a conventional filling method, so that the height and volume of the storage warehouses801are greatly increased, and more materials can be stored.

In one implementation, each storage warehouse801and each ballast warehouse802are elongated and arranged at intervals. As shown inFIGS.3-6, each storage warehouses801and each ballast warehouses802are rectangular, adjacent storage warehouse801and ballast warehouse802share the same long sidewall803, and the short sidewalls of multiple storage warehouses801and multiple ballast warehouses802in parallel form one common sidewall804. In order to store more materials, the width of the storage warehouse801is greater than the width of the ballast warehouse802.

In order to facilitate the long-term storage of materials, a waterproof layer may be formed on the four sides and bottom of each storage warehouse801(that is, a second waterproof layer may be constructed on the baseplate layer604) to enhance the waterproof effect.

(6) Construction of the High-Level Terrace

Conventionally, the stacking-reclaiming device9used in a storage field mainly includes a stacker and a reclaimer, and is very heavy. In the normal use, in order to facilitate the walking of the stacking-reclaiming device9, it is often necessary to drive piles on the foundation, then lay a track beam on the ground and lay a track for allowing the stacking-reclaiming device9to walk thereon on the track beam.

In the stacking yard3of the present application, the stacking-reclaiming device9also requires a special walking track. As described in the step (4), a high-level terrace7with a larger height may be built based on the low-level terrace6, thereby forming the walking condition of the stacking-reclaiming device9. However, if a plurality high-level terrace7passages are blindly built on the low-level terrace6, the high-level terrace7will occupy more space, thereby squeezing the space for the warehouses8.

In one implementation, in order to solve the above problem, the high-level terrace7can be built on the warehouses8. More specifically, as shown inFIGS.3-6, a main road701of the high-level terrace7is constructed in a direction roughly perpendicular to the length direction of the elongated or rectangular warehouses8; and, the warehouses8corresponding below the main road701are provided with support plates805, and the support plates805may be steel plates or reinforced concrete plates, forming the condition of supporting the stacking-reclaiming device9to walk on the main road701. As shown inFIGS.5and6, branch roads702of the high-level terrace7are formed above the ballast warehouses802to communicate with the main road701, and can also allow the stacking-reclaiming device9to walk thereon. Specifically, the long sidewalls803of the ballast warehouses802can be made of reinforced concrete, steel structures or other materials with high strength, and have a height roughly equal to that of the high-level terrace7(or the main road701), so that the walking track of the stacker and the reclaimer can be paved on the long sidewalls803of the ballast warehouses802.

By providing the main road701and the branch roads702of the high-level terrace7, the stacking-reclaiming device9from the main rod701can reach each branch road702so as to stack or reclaim material in the length direction of the storage warehouses801. As shown inFIG.6, the stacker can walk along the branch road702on the ballast warehouses802in the second row, so as to stack material in the storage warehouse801in the second row.FIGS.5and6are schematic diagrams after material stacking.

As shown inFIG.4, connecting beams806are provided on the long sidewalls803of each ballast warehouse802, and are located in the upper portions of the long sidewalls803of the ballast warehouse802to connect two adjacent long sidewalls803in the ballast warehouse802. For example, the plurality of connecting beams803may be arranged between the two long sidewalls by welding. With this arrangement, the upper portions of the long sidewalls803can be connected together to overcome the outward lateral pressure applied to the long sidewalls803by the above load (e.g., the stacker/reclaimer), thereby improving the bearing stability.

It is to be noted that the order of the steps in the implementation is merely a descriptive order and can be adjusted according to actual needs, so this descriptive order does not constitute an absolute limitation to the present application.

In this implementation, by directly building the low-level terrace6in the pit2and making the low-level terrace6lower than the average water level at the outer wide, the staking yard/warehouse space is increased. Furthermore, in the implementation, since most of the area in the pit2is directly used as the stacking yard/warehouses, the conventional engineering of filling the pit2is avoided, a large amount of consumption of the filler and labor and machinery is saved, and the cost-effectiveness ratio of engineering is greatly improved.

A second implementation of the present application provides a water replacement type storage field, which can be constructed by the construction method described in any one of the above implementations.

The water replacement type storage field includes a water-stop enclosure1and a stacking yard3, wherein an outer side of the water-stop enclosure1abuts to water body; and, the stacking yard3is formed in an inner space enclosed by the water-stop enclosure1and located on a pit2formed after draining water in the water-stop enclosure1.

The water-stop enclosure1has a water stop function and prevents the water body at the outer side from entering the water-stop enclosure1. The water-stop enclosure1may be constructed by a method for constructing an enclosure1in the prior art. As one implementation, the water-stop enclosure1includes a plurality of cylindrical steel plates1011and auxiliary steel plates1012located between adjacent cylindrical steel plates1011. The cylindrical steel plates1011are cylindrical, and are distributed at intervals in the length direction of the water-stop enclosure1. The auxiliary steel plates1012are arc-shaped, and are closely connected with the cylindrical steel plates1011through mortise grooves on the cylindrical steel plates1011to stop water. In one implementation, two auxiliary steel plates1012arranged oppositely are provided between adjacent cylindrical steel plates, the arc-shaped convex surface of each auxiliary steel plate1012faces outward, and an inner cavity1013is formed. Backfilling soil is back-filled to the interiors of the cylindrical steel plates1011and the inner cavities1012to increase the stability of the water-stop enclosure1.

Optionally, riprap mounds4are arranged at the inner and outer sides of the water-stop enclosure1, respectively. Thus, the lateral pressure on the water-stop enclosure1by the stacking material on the inner side can be reduced and a back pressure can be produced for the foundation; the acting force on the water-stop enclosure1by the wave or water flow is reduced, and a back pressure is produced for the foundation; and, the stability of the water-stop enclosure1is improved. A wave wall5may be provided on the top of the water-stop enclosure1to reduce overtopping waves.

The stacking yard3includes a lower low-level terrace6and a higher high-level terrace7. The low-level terrace6includes a water permeable cushion601, a water blocking cushion602, a waterproof layer603and a baseplate layer604distributed bottom up. The water permeable cushion601has a water permeable function, may be formed by paving water permeable material (e.g., gravel, sand) in the pit2, and has a thickness of 200 mm to 3000 mm. The water blocking cushion602is a cement layer or a concrete layer, has a certain water blocking effect, and has a thickness of 100 mm to 300 mm. The waterproof layer603is formed by coating waterproof material or paving a physical waterproof layer on the water blocking cushion602, and has a thickness of 0.1 mm to 10 mm. The baseplate layer604is a cement layer or a concrete layer which is a working surface layer, and has a thickness of 300 mm to 2500 mm. The baseplate layer604is further provided with ground beams6041arranged at intervals, and the ground beams6041are a plurality of plate structures arranged in parallel and are formed by extending the baseplate layer604downward.

The surface of the low-level terrace6is at least 1 m (for example, 1 m to 20 m, such as 2 m, 3 m, 5 m, 8 m, 10 m, 12 m, 15 m or 18 m) lower than the average water level at the outer side of the water-stop enclosure1. The space originally occupied by the water body is utilized, and the material storage space is greatly increased.

Warehouses8including storage warehouses801and ballast warehouses802are arranged on the low-level terrace6. The storage warehouses801and the ballast warehouses802are distributed adjacent to each other. The storage warehouses801are used for storing material, and the ballast warehouses802are used for filling ballasts to complement the weight of the storage warehouses801when the weight of the storage warehouses801is insufficient, to increase the downward loading force of the low-level terrace6.

As shown inFIG.4, in one implementation, the storage warehouses801and the ballast warehouses802are rectangular and arranged at intervals, and the width of the storage warehouses801is greater than that of the ballast warehouses802. Adjacent storage warehouses801and ballast warehouses802share the same long sidewall803, and the short sidewalls of multiple storage warehouses801and multiple ballast warehouses802in parallel form one common sidewall804.

The high-level terrace7can be built on the low-level terrace6and used for allowing the stacking-reclaiming device9to walk thereon. In one implementation, the high-level terrace7includes a main road701and a plurality of branch roads702communicated with the main road701. As shown inFIGS.3-6, the main road701is arranged perpendicular to the length direction of the storage warehouses801and the ballast warehouses802and located above the storage warehouses801and the ballast warehouses802, and the branch roads702are formed above the ballast warehouses802.

Further, support plates805are vertically arranged in the warehouses8(the storage warehouses801and the ballast warehouses802) located below the main road701, and are reinforced concrete plates or steel plates used for supporting the main road701. The long sidewalls803of the ballast warehouses are reinforced concrete and steel structures and have a height equal to the height of the main road701, so that the upper portions of the ballast warehouses802act as the branch roads702for paving the track of the stacking-reclaiming device9, as shown inFIG.7. In addition, a plurality of connecting beams806can be arranged in each ballast warehouse802and is located between the upper portions of two opposite long sidewalls803of the ballast warehouse to connect the two sidewalls, thereby improving the pressure resistance. In the present implementation, the long sidewalls of the ballast warehouse can also be used as the foundation of the walking track of the stacking-reclaiming device, without occupying the additional space for establishing the track foundation, so that the storage space of the warehouses8is increased.

The embodiments are only described as preferred embodiments of the present application, and are not intended to limit the scope of the present application. Various modifications and improvements made on the technical solutions of the present application by ordinary skill in the art without departing from the design spirit of the present application shall fall within the protective scope confirmed by the claims of the present application.
