TECHNICAL FIELD
Described is a multi-part reusable levee system bag with biodegradable portions. More particularly, a two piece reusable levee bag having a top and bottom bag section which are removably affixed to each other and in which the bottom section is made substantially of a resilient biodegradable material.
BACKGROUND
Flood control and levee systems have been achieved by utilizing one time use sand bags and the like. However such bags may only be used for a single installation and are labor intensive to fill. Further these bags must be stacked vertically to prevent flooding requiring labor intensive operation and are destroyed when disassembled. It is therefore desirable to utilize bags which may be automatically filled utilizing a backhoe or other machinery and which mechanizes the bag filling operation as well as using a bag which may be reused in multiple installations.
Such prior art bag filling systems have also utilized large filling sleds with a unitary bag construction which allows a larger volume bag to be filled by a mechanized process. However these large volume bags, once filled, cannot be reused and also must be destroyed once the need for the temporary levee has passed.
Thus there is a need in the art to provide a method and bag system as well as an apparatus which provides a portable and reusable levee bag. The levee bag may be filled on location and subsequent to the need for the temporary levee, may be removed, reconditioned and then reused. The methods, system and apparatus for a multi-part reusable levee bag as set forth herein may, for example, allow for reuse.
SUMMARY
The present disclosure is directed towards methods and apparatus for a multi-part reusable levee bag. The multi-part reusable levee bag is, in various embodiments, a multi-part bag which may be filled with a flowable material such as sand and which may then be emptied after use. The bag may then be reconditioned and reused. For example, a two piece bag having an upper portion and a lower portion may be connected and filled with sand utilizing a levee bag filling frame or sled. In some embodiments, the multi-part reusable bag may include a top bag section which is removably attached to a bottom bag section. The top bag section may be configured to be attached securely to the bottom bag section such that an interior enclosed space is defined which securely retains a flowable material. The filled multi-part reusable levee bag may be utilized in flood control projects, earthen support and like applications. In even further embodiments, the bottom bag section may be made of a strong biodegradable material such that, if left in place after removal of a non-biodegradable top bag section, the environmental effect of use of such bag is significantly reduced.
Generally, in one aspect, a multi-part reusable levee bag is provided for filling, emptying and reuse.

DETAILED DESCRIPTION
Levee bags may be filled and installed in various locals and for multiple purposes. These filling operations and bag designs typically are minimal in nature or do not allow for reuse of the levee bags. Previous levee bag systems have typically been filled and left in place and then destroyed upon passing of the need for the levee bags. Thus, Applicants recognize and appreciated the need for a multi-part reusable levee bag which may be easily filled in place and, after filling and use, may be disassembled, reconditioned and reused. For example, a reusable multi-part levee bag may be utilized in a flood location and, after the need for the levee bag has passed, the levee bag may be disassembled and reused. The multi-part reusable levee bag set forth herein, for example, includes various structures for disassembly of the filled levee bag since typical levee bag systems, once filled, must be destroyed in order to remove the levee bag from the filled position.
More generally, Applicants have recognized the need for a multi-part reusable levee bag system which may be filled in position and which may be disassembled and reused at a later time.
In view of the foregoing, various apparatus and methods are disclosed herein which relate to the use, filling and construction of a multi-part reusable levee bag.
In the following detailed description, for purposes of explanation and not limitation, representative embodiments disclosing specific details are set forth in order to provide a thorough understanding of the claimed invention. However, it will be apparent to one having ordinary skill in the art having had the benefit of the present disclosure that other embodiments according to the present teachings that depart from the specific details disclosed herein remain within the scope of the appended claims. Moreover, descriptions of well-known apparatus and methods may be omitted so as not to obscure the description of the representative embodiments. Such methods and apparatus are clearly within the scope of the claimed invention. For example, various embodiments of the apparatus disclosed herein are particularly suited for a multi-part reusable levee bag with a particular orientation for construction as well as geometric shape. Accordingly, for illustrative purposes, the description included herein is often discussed in conjunction with particular implementations described in the figures. However, other configurations of the multi-part reusable levee bag are contemplated without deviating from the scope or spirit of the claimed invention.
FIG. 1 details a multi-part reusable levee bag 100 which is positioned within a bag filling frame or sled 200. As disclosed and set forth within the fill operation depicted within FIG. 1, the multi-part reusable levee bag 100 is positioned in a fill station where the expanded section 50 is expanded for receiving a fill material such as sand and the like. The reusable levee bags 100 further includes, as depicted within FIG. 1 and the embodiment thereof, a collapsed section 58 which is compressed in accordion fashion and which may be expanded as the filling operation proceeds.
In some embodiments the bag 100 may be installed within the bag filling frame or sled 200 and a backhoe or other machine may scoop material into the filling frame and fill the bags as they are expanded into the expanded section 50. Thus, high speed filling of the bags may be implemented.
FIG. 2 depicts a partially filled bag 100 in which the frame 200 has been retracted from the filled portions of the reusable levee bag. Reusable levee bag 100 may include an upper section 30 and a lower section 20 which are removably assembled together to form an interior space within which the fill material is firmly positioned. As shown in FIGS. 1 and 2, once filled, the reusable multi-part levee bag 100 may be disassembled by disconnecting the various connector mechanisms attaching the top bag portion 30 to the bottom bag section 20 thereby allowing the fillable material to flow exterior to the assembled bag and the bag portions subsequently removed.
As further shown in FIGS. 3 and 4, the top bag section 30 includes an end panel 39 as well as an opposing end panel not shown in this view. At least one baffle or side panel 34 is interposed between opposing end panels. As well, a first side panel 31 and a second side panel 33 define an open top 32 and an open bottom 35. In some embodiments, the open top 32 is dimensionally smaller or narrower than the open bottom 35. End panel 39 may be positioned on a first end with the opposing end panel being a corresponding side panel. Further, the plurality of baffle panels or side panels 34 may be regularly intermittently positioned between end panels to form individual compartments which extend the length of the top bag 30 as well as reusable multi-part bag 100.
Top bag portion 30 may have opposing end panels 39 with a plurality of baffle or side panels 34 interposed therein and connecting the first side 31 and the second side 33 such as for example the front and rear surfaces of the bag 100. Use of such multiple compartments formed within the interior of the top bag 30 provides the filled bag with a solid constitution and allows the multiple compartments to be individually filled while also preventing the material from flowing out should a single compartment be torn or otherwise exposed.
The top portion 30 may also include a plurality of guides 38 extending upward from, in some embodiments, both the first side panel 31 and the second side panel 33. Other connection points may as well be implemented such as placing guides along top edges of end panels, side panels or baffles or any other relevant position.
As shown and depicted in the various embodiments of the figures, the guides extend from a top edge of the side panels and include, as shown in FIG. 5, a guide head 40 and a guide neck 42 which allows the guide to slide along a first and second channel 50 of the bag filling frame 200. Various other guide mechanisms may be utilized apart from the specific guides depicted herein and particularly, alternative constructions of guides which allow the bag to slide along any bag filling frame or sled may be utilized. Such implementation of the particular guide shown in the figures is not to be construed as limiting as many other constructions are available to be utilized to accomplish sliding of the top bag and multi-part levee bag within a frame.
An alternative guide structure and embodiment for the levee bag is shown in FIG. 6 wherein a sleeve 45 extends across the top edge of the end panel 39 and the baffle or side panels 34. In such structure, the guide 70 is positioned transverse to the longitudinal axis of the reusable bag system 100. The sleeve 45 may be continuous, intermittent or may be loop retention structures which receive a hangar bar 70 or guide therethrough. Hangar guide bar 70 can be of various constructions as long as it can support or at least partially support the assembled reusable bag 100. The hangar guide bar 70 may extend through such loops or sleeve 45 and be slidably retained on the frame 200 by inverted L-shaped brackets positioned on either end of the guide 70. These brackets may then slide along the runner 80 positioned at the bottom of the hopper panels 82 allowing the reusable bag to slide below the hopper. The hangar bars 70 may then support the bag along a transverse direction of the reusable bag 100.
Reusable bag 100 may also include upper or top bag portions 30 which are made of a differing material than the bottom bag portions 20. Top bag 30 may be made of a strong thermoplastic based material, such as polypropylene, which can withstand significant force during assembly, filling and disassembly of the two-part bag. Top bag portion 30 typically receives substantial tearing or shearing forces during the filling or disassembly operation and thus it may be desirable to manufacture the top bag portion 30 of a strong more resilient material. Alternatively, the reusable two part bag 100 may include a bottom bag portion 20 which may be comprised of a natural plant fiber based material and thus, upon disassembly, may remain in place without having a negative environmental impact.
The top bag portion 30 may, in various embodiments, be substantially comprised of a non-biodegradable material. The top bag portion may further, in some embodiments be made of a mix of biodegradable and non-biodegradable material. The top bag portion may further, in still other embodiments, be substantially comprised of biodegradable material.
The bottom bag portion 20 may, in various embodiments, be substantially comprised of a biodegradable material. The bottom bag portion may further, in various embodiments, be made of a mix of materials, said mix of materials being substantially biodegradable. Thus, an amount of the bottom bag portion may readily biodegrade with other non-substantial non-biodegradable materials provided in the bottom bag portion to increase strength and stability. A mix of thermoplastic and biodegradable materials may thus comprise the bottom bag portion, in various embodiments and constituent percentages. The non-substantial non-biodegradable portions of the bottom bag 20 may be positioned in structurally significant areas, such as seams or load bearing areas. Or, the non-substantial portions may be made of a differing biodegradable material. However, the bottom bag 20, even though having a mix of biodegradable material forming a substantial portion there, may readily and substantially be subject to biodegradation.
In some embodiments, the bottom section 20 may be made of a biodegradable material such as jute or other plant based fibers. Such materials provide resiliency and strength but are readily biodegradable after prolonged exposure. Such materials may be a natural fiber, animal or vegetable fibers and more particularly may be bast fibers or more particularly a ligno-cellulosic fiber. Alternative materials include hemp, ingeo, calico, cotton, bamboo, organic wool, ramie, tencel or nettle. By biodegradable, it is meant to include, among other things, the chemical dissolution of materials by bacteria or other biological means capable of decomposing substantially back to natural elements. This may further include artificial materials that are similar enough to plant and animal matter to be put to use by microorganisms. Such variant embodiments are not considered to be limiting and are provided merely as exemplary as various other biodegradable plant based, organic, artificial or other material may be used to form the bottom section 20.
It may be desirable in some embodiments to utilize a biodegradable material such that, upon disassembly of the reusable bag 100, the bottom section 20 may remain in place while the top section 30 may be reconditioned and reused. This may be particularly useful if the bottom section 20 is not readily accessible due to flooding, mud cake or other issues.
As depicted in the various figures and as well in FIG. 6, the top bag 30 is removably affixed to the bottom bag portion 20 utilizing a number of various connectors 25. Once the reusable levee system bag 100 is assembled and filled via the frame 200, the interior compartments of the bag between end panels 39 are filled with sand or like fillable material. As depicted in 4, the top bag portion 30 may be pulled away from the bottom bag portion 20. During this disassembly operation, substantial upward force may be required to remove the top bag 30 thereby allowing the fill material to spill. In some instances, it may be desirable to maintain the bottom bag portion 20 in place instead of removing the sand or other material filling the levee bag 100. In some instances, bottom bag portion 20 may become caked or embedded in the soil due to flooding or may merely be inaccessible. As a result, in various alternative embodiments, it may be desirable for the bottom bag portion 20 to be made of a biodegradable material such that it may be left in place without having a negative environmental impact.
In various embodiments, a top bag portion may include a thermoplastic material and may be combined with a bottom bag portion comprising at least a substantial amount of biodegradable material. In various embodiments, the bottom bag portion may formed of jute or similar organic or plant based material. Such bottom bag portion may be formed using known textile methods, particularly using alternative strengthening material along seams and other areas to ensure the structural integrity of the bottom bag portion and of the affixation of the top bag portion thereto. Thus, the bottom bag portion may be primarily made of a biodegradable material while also including a strengthening non-biodegradable material. Alternatively, the bottom bag portion may be comprised of substantially all biodegradable material with a mix of varying strength such material mixed in different amounts or at differing locations of the bottom bag. Various alternative connectors 25, as described herein, may be utilized to secure the biodegradable bottom bag portion to the top bag portion.
Returning to FIGS. 3 and 4, the top bag 30 includes the end panel 39 shown in the figure and having opposing first and second side panels 31, 33. The end panels and first and second side panels in combination with the baffles or side panels 34 form an interior space in which the fillable material may be deposited. The top bag further has an open top 32 and open bottom 35, the open bottom substantially closed off by the bottom section 20 and bottom panel once connected to the top bag 30. The bottom panel of the bottom section generally is in alignment with the open bottom 35 of the top bag 20. In various embodiments, the bottom section 20 may include first and second side flaps which extend up upward on the exterior surface of the top bag portion 30 so that the D-rings 25 are accessible to the straps 37. However, many other constructions are available for positioning of the bottom section 20 in general alignment with the open bottom to effectively seal the open bottom of the top bag from dispensing fill material.
The bottom bag is, in various embodiments, removably attached to the top bag 30 by various removable attachment mechanisms and may be, in one embodiment, connected by a plurality of straps 37. The straps 37 may depend or extend on an exterior surface of the top bag and be received within strap receiving mechanisms 25. The strap receiving mechanisms may include rings, D-rings, loops or other structure and as well, the position of the straps and strap receiving mechanisms may be interchanged. For example, the straps may extend upwards from the bottom section to be received at the top bag or other configurations to effectively connect the two sections together.
Various known removable attachment mechanisms or connectors may be interposed between the top bag 30 and the bottom bag portion 20 such that the top bag portion may be removably affixed and attached to the bottom bag portion in order to define an interior space which may receive fillable material and which allows the top bag to be removed and separated from the bottom bag after filling. Such removable attachment mechanisms or connectors allow the top bag to be securely affixed to the bottom bag during the filling operation and during use and may include straps, hook and loop fasteners, mechanical buttons, zip systems, temporary stitching, fold lines, flaps or other structure. Various such connectors, removable attachment structures or removable affixation means may be implemented to removably affix the top bag to the bottom bag and the embodiments shown herein are provided to exemplify one variation of removably attachable mechanisms to removably attach the two portions together.
As shown in the figures, the top bag has an open top 32 and an open bottom 35 wherein the open bottom is larger in diameter or area or dimensionally larger than the open top 32. In the depicted embodiment, the larger opening at the bottom allows more ready dispensing of the interior fillable material contents of the multi-part bag once disassembly and detachment of the two portions is completed. As well, in various embodiments, similar sized openings for the top and bottom of the top bag portion may be implemented. Narrowing of the upper entry area or open top of the top bag as compared to the open bottom area of the top bag is not necessary in order to effectuate a multi-part reusable levee bag as described and illustrated herein.
The open bottom of the top bag may be closed off with the bottom portion 20, the bottom portion 20 including a central bottom panel 28 and first and second side flaps 21, 23 both of which extend upward towards the open top of the top bag portion. The first and second side flaps may be wrapped on an exterior or interior surface of the top bag and is designed to effectively close off the open bottom 35 of the top bag and prevent significant dispensing of the flowable material once contained into the interior area of the multi-part bag. By wrapping the side flaps 21,23 around the walls of the top bag, flowable material within the compartments of the assembled bag does not leak through when the bag is submerged or exposed to water or current. Alternatively, and in various embodiments, an end flap 22 may also be provided which may be folded up along the bottom edge of the end panel 39 of the top bag and be secured thereto in order to prevent leakage of the fillable material out of the lower edge of the end panel 39. Such end flap 22 may be connected to the end panel 39 by hook and loop type fasteners, buttons, straps or other removably affixable mechanisms. End flap 22 may as well be constructed in alternative embodiments as a V-shaped configuration to receive between each V-shaped panel the end panel 39 of the top bag. By including the end panel 39 of the top bag into a V-shaped end flap 22 of the bottom bag portion 20 or a single end flap, as shown in the various embodiments, securement of the end panel 39 of the top bag and prevention of leakage for sand or other flowable material occurs. Such various alternatives of the removably affixable mechanisms may be utilized throughout the construction of the multi-part reusable levee bag illustrated herein in combination with other functionally similar structures.
As illustrated in the various embodiments depicted within the figures, the top bag 30 may have a generally multi-sided or quadrilateral cross-sectional shape which utilizes a narrower top and a wider bottom in order to increase the stability of the filled multi-part reusable levee bag. The construction of the levee bag as shown in the various embodiments may as well increase the ability of the top bag 30 to be lifted away from the bottom bag section 20 once the levee bag has been used. The bag cross section may be quadrilateral, multi-sided or alternative shape. As well, in various constructions, the bags may be various cross sections. In some examples, this cross section may be multi-sided. However, such is merely exemplary and provided for explanatory purposes only. Further, among the multiple embodiments and examples provided, it is merely meant, among other non-limiting examples, that the cross sectional shape may generally be square, a convex quadrilateral with at least one pair of parallel sides and may also include a five or more sided polygon. As set forth in the various depicted embodiments, a multi-sided top bag is disclosed with a smaller length top edge as compared to bottom edge. However, alternative constructions having non-parallel edges or mating walls may be implemented. Alternatively, however, in some embodiments the bag may have more than four sides and may be a complex shaped, five or more sided configuration.
Other constructions and shapes may be utilized for the top bag 30 and the cross-sectional shape depicted herein and within the figures is merely used for explanatory purposes only. No limiting interpretation of the specific geometric dimension and shapes shown in the figures is to be read into the appended claims or interpreted as being necessary to accomplish the various structures and methods of the apparatus disclosed herein. Such alternative constructions include square, triangular, rectangular and other geometric configurations allowing the interior of the combined top and bottom bag portions to be filled.
In use and as provided in this example, the top bag 30 and the bottom bag 20 may be removably affixed together as shown in various figures and installed within a bag filling frame 200. Sections of the combined top and lower bag sections may be positioned in the frame in an expanded orientation 50 with other sections in a collapsed orientation 58 as depicted in FIG. 1. Thus, long stretches of the combined bag may be installed within a frame for filling in rapid succession. The combined bags may be slidably retained within the frame 200 by a plurality of guides 38 which are received within guide receiving channels 50. The expanded bag section 50 may be placed under a funneled filling area of the frame so that sand or other fillable material may be deposited into the funnel area and fall directly into the expanded or opened section of the multi-part bag. Strap handles 52 and 54 may be positioned at various points on both the bottom bag 20 and the top bag 30 in order to aid in both the installation, assembly and then subsequent disassembly of the multi-part reusable levee bag 100.
The combined multi-part reusable levee bag may be slidably retained within frame and filled while the frame is slowly retracted backwards towards the collapsed section 58 of the combined top and bottom bag sections thereby producing a combined filled bag portion and unfilled bag portion as shown and illustrated in FIG. 2. The sled 200 may be retracted over the collapsed section in order to easily expand the collapsed bag section 58 into an expanded bag section 50 for filling as shown in FIG. 1, so that the filling operation may continue.
After filling of the bags in place, the combined multi-part reusable levee bag may act as a levee bag for flood control, retaining walls, earthen dam, erosion control, concrete walls, and other known uses. The multi-part bags may further be disassembled and reused by removing the fillable material therein without destroying the integrity of the bags.
As shown in FIG. 4, the top bag portion 30 may be detached from the bottom bag portion 20 by disconnection of the straps or detachment of other removably attachment or affixable structure. As shown, once the straps or other mechanism are detached, the top bag portion 30 may be lifted away from the bottom bag portion 20, thereby spilling the interior contents of the fillable material and allowing the top and lower or bottom bag sections to be reused. Straps 54 extending along the top edge of either side of the top bag may be utilized for raising the top bag 39 away from the bottom bad section 20 and allowing the contents therein to flow through the open bottom 35 and the top bag to be pulled away from the fillable material and bottom bag section. Remaining fillable material may be moved aside of the bottom bag portion 20 and the bottom bag portion may similarly be reused.
In various constructions, the top bag and bottom bad may be made of various materials including polypropylene, high strength canvas or the like. It may be desirable to incorporate material which is in impervious to water and which sufficiently retains the fillable material therein. The fillable material may include not only sand, dirt or other fill material but may also include concrete and the like should a permanent structure be required.
While several inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the inventive embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.
All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.
The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.”
The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.
As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited.
In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.
