<p>Water dam including a number of loading pallets arranged side by side and inclined outward from the water supported by supports (2). Membranes (3) are placed on loading pallets and a distance in front of these in 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 can not be tilted by the water. To achieve this and get a good grip on the ground the inclination is preferably 45°, this resulting in great vertical forces on the ground, giving a good grip on this.</p> |
