ABSTRACT:
A barrier wall for containment of flood waters composed of multiples of modules which are easily transported to the site and erected without tools, by only a few persons with no special skills or training. Flexible coversheets, having foam seals which conform the modules to the ground and prevent flood waters from undercutting the ground and rendering the wall unstable are placed on the ground. Compartmented flexible ballast cell units are placed on the cover sheets just over the seals. The edges of the coversheets are coupled together as are the ends of the ballast cell units for continuity of the wail. The ballast cells can then be filled with water, sand, earth, gravel or other available material and the front portions of the cover sheets brought up and over the ballast cells to form a wall. An additional tier can be added to double the height of the wall. When waters are expected to rise higher than twice the height of the cells, one tier of ballast cell units is used and lightweight support trusses are positioned in the ballast cells before they are filled. Connectors and guy wires add stability to the trusses. The front portions of the cover sheets are then brought up and fastened to the tops of the trusses on the side facing the flood waters. Rigid armor plate sections can be placed over the cover sheets to protect them from being damaged by floating debris. The front edges of the trusses form a catenary curve which defines the face of the wall and serves to transmit the force of the water downward reinforcing the seal to the ground. Any number of modules can be used and will conform to the terrain.
