PCT No. PCT/SE96/01002 Sec. 371 Date Feb. 10, 1998 Sec. 102(e) Date Feb. 10, 1998 PCT Filed Aug. 9, 1996 PCT Pub. No. WO97/07290 PCT Pub. Date Feb. 27, 1997A 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 DEG , resulting in great vertical forces on the ground, a good grip on the ground. |
