Abstract

L'invention concerne une structure temporaire à parois de retenue de sol installée des deux côtés intérieurs d'une partie d'excavation (2) pour éviter l'effondrement de la paroi latérale de la partie d'excavation (2) formée par des travaux de fondations effectués dans le sol (1). La structure temporaire à parois de retenue de sol selon l'invention est caractérisée en ce qu'elle comprend : plusieurs conduits de guidage (100) présentant un orifice traversant (101) destiné au guide de conduit intégré s'étendant profondément et verticalement dans le sol, les conduits de guidage (100) étant installés adjacents sur un côté de la partie de l'excavation (2), à une certaine distance de celle-ci; une plaque supérieure de retenue de sol (110) accouplée au côté arrière des conduits de guidage (100); une plaque inférieure de retenue de sol (210) montée entre plusieurs conduits intégrés (200) par glissement le long d'une rainure de guidage (103) formée entre le conduit de guidage (100) et la plaque supérieure de retenue de sol (110). Ainsi, la structure temporaire à parois de retenue de sol présente l'avantage de permettre de réaliser des constructions de manière pratique et en toute sécurité, et d'augmenter le taux de recyclabilité des matériaux.
