Definitions

  • the present invention relates to temporary flood walls. More particularly, the present invention relates to a system which utilizes a continuous sleeve that is fitted into each connecting wall. This sleeve provides a stiff and straight support for the entire length of the connecting walls by use of a metal rod which is threaded through the sleeve and supported by the metal rails of the sled or any other hanging device that may be used.
  • the present invention also describes a filling device that allows heavy equipment such as front end loaders to efficiently fill the cellular barrier will no loss of fill materials while providing a smooth even, level top to the filled barrier wall.
  • the individual cells of the wall can be filled with up to 7,000 pounds
  • Still another method uses open top bulk bags with wooden frames inside them which are bolted together in a cellular fashion to create vertical long walls that are then filled with sand and dirt. It is a fairly fast method for constructing walls but has the expense of the wood and is limited to vertical walls that can be pushed over by fast moving flood waters or collapsed from beneath as the flood waters hollow out the ground beneath them.
  • Still another method uses specially shaped bags that have triangular shaped sides. These bags are delivered using a large sled device that makes filling easier and faster than the methods listed above.
  • this sled device relies on a bag support method that requires special parts to support each bag by its four corners that can be expensive and unreliable.
  • the triangular shaped front of the containers are often unfilled due to its pointed toe. Due to the wave action of the flood waters, the sand and dirt can move after placement and cause some loss of control over its shape. And, just as the square bags can be hollowed out from below, so can this triangular faced design.
  • a system and method of constructing any desired length or height linear cellular chain for use as a protective wall system, made of flexible materials comprising the following providing an end panel made of flexible materials; each end panel shaped such that it will provide a specified shape to a main panel; the specified shape shall have a vertical wall that will define the final height of each cell, a bottom wall that is longer than the height of the vertical wall, a second vertical wall that is sized to allow for the final wall that will slope upward to have at least a 45 degree angle up to an opening for filling that is defined by the top of the vertical wall and the top of the sloped wall; providing a sleeve of similar flexible materials at the top of each end panel that are essentially the full length of the defined opening and tall enough to accept a support rod for filling; providing a main panel section made of essentially the same flexible material that equals the length of the enclosed dimensions of a completed cell by sewing one edge of the
  • the chain is then positioned onto a sled which accommodates a plurality of unfilled bags which move along the sled and are positioned beneath a hopper.
  • the hopper fills the plurality of bag simultaneously, and after being filled, the bags are rolled from the sled and are in position to serve as a portion of the barrier together with other plurality of bags to define the overall chain.
  • This invention still uses flexible fabric to create a continuous cellular wall as does the second two methods above. However, it requires no wood nor any special and unreliable parts to hold it up during the filling process. It has no pointed toes that are difficult to fill. But most importantly, it resolves the problem caused by the flood hollowing out the ground beneath the barrier. By eliminating this particular problem, this invention provides far more security to any property being protected by this barrier wall than any previous method involving flexible fabrics.

  • Figures 1 through 19 illustrate the TrapBag® system and method the present invention of filling a continuing series of bags or chambers to ultimately define a barrier wall.
  • this invention replaces the method of support as seen in the prior art with a unique sleeve support system. Instead of four individual plastic hangars that can break and allow connecting walls to sag and misshape, this invention uses a continuous sleeve that is fitted into each connecting wall. This sleeve provides a stiff and straight support for the entire length of the connecting walls by use of a metal rod which is threaded through the sleeve and supported by the metal rails of the sled or any other hanging device that may be used.
  • This sleeve and bar method can be used on barriers of almost any design. It can be used on both straight sided containers such as bulk bags or it can be used on slope sided containers such as discussed in this invention.
  • a second feature of this invention is the elimination of the pointed toe that often cannot be filled.
  • the angle of repose and the coefficient of friction of the various materials used to fill them can often prevent the fill materials from reaching the end of the toe.
  • This invention simply eliminates this problem by designing a blunted end of the container and keeping the non-vertical side wall at or near a 45 degree angle.
  • a third feature of this invention is the use of the 45 degree slanted wall on one side of the flood wall. By sloping the wall facing away from the rising water, the sloped wall adds triangular force to prevent wall collapse. Bags with simple vertical walls are prone to tipping over from the force of the water.
  • the wall By adding the slope opposite the force of the water, the wall has greater resistance to tipping over than even a similarly based container with vertical walls. As a vertical wall begins to tip, the weight of wall that immediately crosses the vertical position becomes encouragement for the wall to tip over. With a sloped side, there will be no weight crossing the vertical line and encouraging the container to tip over. Further, the center of gravity for the entire container is moved toward the force of the water creating even further resistance to tipping over.
  • the slope of the container can also be placed facing the water. Due to the shape of the container, there is a greater percentage of weight in the bottom half of the container. Further, when the sloped side is facing the water, it provides a few different advantages.
  • the sloped side deflects any wave action upward in a harmless direction.
  • wave action hits the vertical side some of the wave action is directed downward where it can be involved in hollowing out the base under the container.
  • a fourth feature is an optional wave protector.
  • Figures 1 -12 illustrate views of the construction of the bulk bags used in the system of the present invention
  • Figures 13 through 18 illustrate views of the sled and hopper machinery utilized in loading sand or other material into the bags, and the method of filling the plurality of bulk bags during the process.
  • FIG. 1 illustrates a plurality of the chambers 10 engaged to one another with the dimensions of each chamber 10 set forth in the preferred embodiment.
  • chambers 10 may also be referred to as "bags" or “cells” herein.
  • the chambers 10 include a pair of sidewalls 12, 14, which are basically triangular in shape, having a floor portion 16, a slanted forward face 18, terminating in a vertical toe portion 20, and a rear wall 22, all of which are secured together via stitching or the like to define a container space 24, therewithin for receiving material, such as dirt, sand, or other material.
  • the upper end 26 of the chamber 10 has an open end 28, into which the materials are inserted into the space 24.
  • Figure 2 illustrates the construction of the side panels 12 by configuring two sides 12 from a single length of fabric cut along the diagonal line 32 as illustrated. The various preferred dimensions of the side panels 12 are shown in the Figure 2.
  • FIG 3 illustrates the sleeve construction and the manner of attachment as described in the drawing Figure.
  • each of the side panels 12 include a section of fabric 35 stitched or sewn to the upper end 26 of each of the panels 12, in an overlapping fashion, to define the upper channel 30, as was discussed in regard to Figure 1 . Again the function of these channels 30 will be discussed further.
  • Figure 4 illustrates the construction of each of the front panels 18 that will be part of each of the chamber 10, in the proper length and width as described.
  • each of the side walls 12 are fitted with the section of fabric 35 to define the upper channels 30 before the side walls 12 are engaged together to define the chamber 10.
  • Figure 5 illustrates the procedure for adding the sleeves to the side panels in the construction.
  • Figure 6 illustrates the sewing of the front panel 18 and the rear panel 22 to the two side panels 12, to define the completed chamber 10.

  • Figure 8 illustrates the manner in which the plurality of chambers 10 are linked to one another, as seen by Arrows 45. Because each chamber 10 is secured to an adjacent chamber 10, along their side walls 12, it is seen that only one of the chambers 10 needs to have a completed side wall 12, so that when the first chamber 10, having both side walls 12 is secured to the adjacent chamber 10, one of the side walls 12 of the first chamber 10 can be shared with the adjacent chamber 10, thereby saving on fabric when construction the plurality of chambers into a continuous barrier wall. It is foreseen, for example, that because of the width of each completed chamber 10, twenty sets of chambers 10 sewn side by side would form a 100 foot (30 m) continuous, uninterrupted chain 50 of chambersl 0 to define a barrier wall.
  • Figure 8 further illustrates the linking together of numerous sets by sewing them together to form any length of chain desired. It is acknowledged that the sewing patterns may be changed to accomplish the same end result. One such way would be to add each piece to a growing line rather than to make up individual groups and then sew them together.
  • Figure 9 illustrates the manner in which one chain 50 of chambers 10 are secured to one another.
  • a chamber 10 at the end of the chain 50 has a plurality of loops 40, preferably 8 in number.

  • the sled 101 is pulled from the front side by a tractor. As the tractor pulls the sled 101 forward, the filled bags stay in place which means the steel rods 1 16 roll off the rails on the back side.
  • the back vertical wall of the sled 101 acts as a leveling and scraping device. It determines the final height of filler material in each bag and creates a potentially flat and level barrier wall.
  • new chains must be added to the back of each accordion chain before the final cell is filled. This is done by enveloping the final cell with the open walls of the next chain and tying them together.
