Abstract

L'invention concerne un système de barrage pouvant à la fois faire office de barrage et de réservoir intermédiaire. Selon l'invention, il est prévu des éléments de base pouvant être assemblés à la manière de «Lego». Ce concept intègre néanmoins non seulement l'assemblage de type longitudinal, mais aussi de type croisé, ce qui permet de réaliser des barrages linéaires, en étoiles et en treillis. L'élément de base comprend des flexibles doubles soufflés en film de poids réduit, maintenus d'ores et déjà empaquetés. La longueur des flexibles doubles soufflés en film peut être adaptée à chaque situation et se situe par ex. entre 5 et 400 mètres. Ce nouveau système peut être combiné en cas d'accidents majeurs avec des barrages lourds de l'état de la technique, mais convient cependant tout particulièrement à des barrages de taille petite et moyenne, car il permet de recueillir et de collecter l'huile de manière particulièrement optimale, par l'intermédiaire d'absorbeurs.
