Device for temporarily stopping licquids to reach non wanted areas. The device is adapted to be used in crise situations. Therefore it has a performance making it easy to store, transport and put up. This has been achived by using a barrier-and sealing fabric (1, 4) non penetratable for the licquid to be dammed. The barrier is preferably stored folded together and rolled (fig.1). When used the barrier's is unfolded and rolled out and its floating bodies filled. The underpart is put flat on the ground extending the flooded side. When the licquid (15) flows in on top of the fabric the space between the fabric and ground is sealed off by the licquids weight (fig. 4, 5, 6). Futher the barrier fabric (1) has attached spaces (6) where separate exchangeable floating bodies (7) are placed which can pull the barrier fabric up when the licquid level rises. To assure the barrier to stay in place the barrier fabric is anchored in it's anchoring eyes. Anchoring is made both in underborder to the ground on the flooded side and in upperborder in eyes close to the floating bodies. Upper anchoring can be made both on flooded and dry side or in combination (fig. 4, 5, 6). Above technique can also be used to build basins and channels. |
