摘要
The system (1) has a barrier insurmountable for the floodwater, which consists of two parallel collapsible walls (2,3) in the vertical direction. The collapsible wall is immersible in a trench (12) in folded condition. The two parallel collapsible walls have a mutual distance and consist of movable, hinged lamellas connected with each other. The lamellas consist of a rigid, particularly water-insensitive material such as metal or plastic.
