Method for accomplishing a dam protection, as well as prepared dam protection module

摘要

The invention is directed to a dam securing module, comprising a base body, which is made of a flexible and substantially water-impermeable sheet material, and sinkers which are connected to the web material, wherein the sinker and the sheet material are interconnected, such that the sheet material with the Senkkörpern is rollable to a developable role. This makes it possible in an advantageous manner, in the context of a flood, at already increased level on the water side of the dam to form a water-impermeable layer through which locally further penetration of water into the dam is greatly reduced. The sinkers cause an initially sufficient investment of the web material on the dam wall, in which case after a short time the system pressure is increased by eliminating the back pressure back and the seal is further supported by the water pressure on the flood side.
