Patent number: 6213683Abstract: A flexible film, of which a flexible film weir is composed, has a two-dimensional configuration when expanded, and the total length of the periphery of the flexible film is set longer than the mounting length of mounting faces (a river bed and faces of slopes). Weights are attached on the flexible film at appropriate intervals. Portions left redundant when the flexible film is mounted on the mounting faces are folded and fixed at toes of the slopes in such a way that they are overlapped. The two-dimensional configuration of the flexible film simplifies the structure. Further, as the weights prevents the weir from floating up, there is no need for forming irregularities on the river bed, thereby simplifying the construction.Type: GrantFiled: January 8, 1999Date of Patent: April 10, 2001Assignee: Bridgestone CorporationInventor: Tateo Muramatsu

Patent number: 6132140Abstract: A water dam includes a number of loading pallets arranged side-by-side and inclined outward from the water supported by supports. Membranes are placed on loading pallets and extend a distance in front of the pallets under the water. The membranes may be held down in the front edge by stones, sand bags, etc. initially to hold the membrane in place. The supports are triangular and made of U-shaped sheet metal beams. The one on which the pallets rest grips over the adjoining legs of two loading pallets to hold these together. To the rear the support is extended sufficient to secure that it cannot be tilted by the water. To achieve this and achieve a good grip on the ground the inclination is preferably 45.degree., resulting in great vertical forces on the ground, a good grip on the ground.Type: GrantFiled: February 10, 1998Date of Patent: October 17, 2000Inventor: Sten Kullberg
