Abstract

La présente invention porte sur une structure de paroi de maintien temporaire, laquelle structure est disposée sur un côté d'une zone d'excavation pour supporter une pression de terre et pour empêcher l'effondrement de terre et de sable pendant un travail d'excavation de sol tel qu'une excavation de tuyaux pour poser des tuyaux souterrains, et analogues, et, de façon plus spécifique, sur une structure de paroi de maintien temporaire variable ayant une constitution couplée à une structure d'ensemble du type insertion afin de permettre à la longueur de chaque élément de varier en fonction d'une largeur d'excavation et d'un déplacement de direction d'excavation. La présente invention a une excellente aptitude au travail et une excellente aptitude à la construction par la réalisation de la structure de paroi de maintien temporaire qui peut être altérée de façon active par rapport au déplacement de la zone d'excavation.
