Bag For Shoring Bank Of Body of Water

Abstract

A bag assembly for repairing a receded bank includes a fabric bag having a closable opening; and a mesh cover surrounding the bag. The bag assembly is filled with a fill material and has an end portion that is fastened to remain closed. The mesh cover can be applied over and around the bag after the bag is filled. The mesh cover is resistant to penetration by burrowing animals, such as muskrats. A method is described for restoring a bank on a body of water that is resistant to burrowing animals and includes the steps of: stacking a plurality of courses of bag assemblies to form a wall spaced from a face of a receded bank, wherein each bag assembly comprises a fabric bag filled with fill material and surrounded by a mesh cover; and filling the void between the wall and the receded bank with fill material. The method can include the further step of before the step of stacking bag assemblies, placing a blanket of mesh over the face of the receded bank.

DETAILED DESCRIPTION

[0016] While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.

[0017] In order to better illustrate the embodiments of the invention, some elements are shown with exaggerated thicknesses or sizes.

[0018] FIG. 1 shows a bank restoration of the present invention. FIG. 1 is a sectional view. It should be understood that the elements of FIG. 1 extend into and out of the page in two or three dimensions. A bank 10 of a body of water has a top surface 14, and a bank face 18 that extends down to bed 26 of the body of water. A burrowing animal, such as a muskrat has excavated a den 32 into the bank, having an opening or entry 36 on the face 18 of the bank. Multiple and repeated burrowing by animals has caused erosion of the bank and the face of the bank to recede from a location A to a location B.

[0019] An exemplary method of the invention restores the bank to the position A in a manner that is preventative of future erosion caused by burrowing animals. A substrate, or blanket 44 of wire mesh is placed onto the bank with an upper portion 48 laid on the top surface 14, a substantially vertical portion 54 placed against the face 18, and a lower portion 58 placed on the bed 26. A wall 70 is built up by stacking one or more courses 72, 74, 76 of bag assemblies 77 along the bank. In the illustrated embodiment three courses 72, 74, 76 of bag assemblies 77 are used. The bag assemblies are placed in a sandbag-stacking manner wherein the joints between bag assemblies of one course are staggered with respect to the joints between bag assemblies of adjacent courses.

[0020] After the first course of bag assemblies is placed, the lower portion of the substrate 44 is bent up into a vertical part 80 and a horizontal part 81 back over the first course of bag assemblies. A second course of bag assemblies is placed onto the horizontal part 81 and the first course to hold the blanket 44 in place.

[0021] One or more courses of bags can be placed below water level W.

[0022] After the wall 70 is complete, the area between the wall 70 and the bank face 18 is backfilled with a fill 84, such as rock, soil, sand or other suitable material. This can be 1 inch gravel and/or 3 inch limestone. A layer of top soil 90 is placed over a top of the last course of bag assemblies and over the fill 84 and over the wire mesh 48 at the top surface 14. The top soil has a top surface 96 substantially flush with the top surface 14 of the bank.

[0023] FIGS. 1A-5 show one bag assembly 77 in more detail. The bag assembly 77 is composed of a bag 78, which can be of nonwoven material that is substantially closed except for an end opening 102 defined between a pair of edge regions 104, 106. When the edge regions 104, 106 are spread apart, the opening 102 is revealed and when the edge regions 104, 106 are closed together the bag 78 is effectively closed. When the edge regions 104, 106 are spread and the opening 102 is revealed, the bag 78 can be filled with rock, soil, sand or other suitable material. The bag 78 can be filled by hand or by use of a sandbag-filling type apparatus. The bag 78 is then closed by pressing the edge regions 104, 106 together and fastening the edge regions 104, 106 to each other. The filled bag is pounded or otherwise pressed to be substantially flat. The entire bag, top, sides, bottom and ends are then wrapped in a wire mesh cover 110 of steel or other material that is resistant to penetration by burrowing animals. The cover 110 is shown schematically in FIGS. 1A and 4. The wire mesh shown is known as chicken wire having a pattern of hexagonal openings. The wire mesh cover 110 can be wrapped around the bag 78 in a manner that is similar to the wrapping of a box with gift wrapping paper. Free edges of the folded cover can be secured by wire ties or nylon ratchet ties or the like, to form an enclosing cover around the bag.

[0024] As shown in FIGS. 4 and 5, the bag 78 has been filled with rock, soil, sand or other suitable material. An adhesive layer 114 has been applied to one or both edge regions 104, 106 between facing sides of the edge regions 104, 106. The edge regions 104, 106 are pressed together and stapled together with staples 118 spaced apart along the length of the edge regions 104, 106. After this occurs, the wire mesh cover 110 can be wrapped and secured around the outer surface of the bag 78.

[0025] According to one exemplary embodiment of the invention, each bag can be composed of a nonwoven fabric, 8-12 mil thick. Each bag can have the dimensions 19 inches wide, 29 inches long and can be 5 or 6 inches tall. The bag can be filled with 1 inch to 2 inch washed gravel, and/or inch to 1 inch limestone chips, and/or dirt and/or sand. Each bag can weigh 50-70 pounds. For closing each bag, an adhesive SUCH AS SURE BOND-EVERSEAL-SB 190 CAN BE USED. The staples can be STANLEY BOSTICH model P6C- inch- inch or inch staples driven by an EVERWIN PS50-10B pneumatic plier stapler. The mesh can be chicken wire inch or 1 inch size, such as EVERBUILT poultry netting.

[0026] From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred.
