CA 2416971

In a method for providing a portable flood barrier (1), flood barrier sections (2, 3, 4) comprising two parallel, spaced apart, inflatable, elongated tubes (5,6 or 5,7) which are joined by a waterproof web (8) are placed on the ground (9) with the side of one of the tubes (6 or 7) facing the flooded area (10), and the other tube (5) facing away from the flooded area (10). Both tubes (5,6 or 5,7) are inflated, and ballast water (13) is filled on the web (8), whereupon, when floodwater (14) rises, the tube (6 or 7) facing the flooded area (10) floats in the floodwater (14) and due to its buoyancy rises, thereby forming a flood barrier (1).

L'invention se rapporte à une barrière portable (1) contre les inondations qui comporte des sections (2, 3, 4) comprenant deux tubes (5, 6 ou 5, 7) oblongs, gonflables, parallèles et espacés l'un de l'autre, qui sont assemblés par une nappe imperméable (8). Lesdites sections de la barrière portable sont placées sur le sol (9) de sorte que l'un des tubes (6 ou 7) présente une face tournée vers la zone inondée (10) et que l'autre tube (5) soit tourné en direction opposée à la zone inondée (10). Les deux tubes (5, 6 ou 5, 7) sont gonflés et de l'eau de ballast (13) est déversée sur la nappe (8). Par conséquent, lorsque le niveau de l'eau de crue (14) monte, le tube (6 ou 7) qui fait face à la zone inondée (10) flotte dans l'eau de crue (14) et s'élève du fait de sa flottabilité, formant ainsi une barrière contre l'inondation (1).
