Abstract

L'invention concerne un procédé permettant de réaliser un mur extérieur de cave directement à côté d'un mur de bâtiment existant, selon lequel des poutres de coffrage sont introduites, à une certaine distance du mur de bâtiment existant, dans le sol de fondation, et le mur extérieur de cave est réalisé en suivant la progression du déblaiement, à l'aide de plusieurs sections de mur qui reposent contre les poutres de coffrage. Le procédé se caractérise en ce que les poutres de coffrage (3), dans leur zone supérieure, se présentent sous la forme de poutres en porte-à-faux (5) ou sont maintenues par au moins un support (6) et, dans leur zone inférieure, sont soutenues par un support inférieur (7), et en ce que les éléments de support (8) sont placés sur la poutre de coffrage (3) de façon à pouvoir être déplacés horizontalement et sont, après avoir atteint leur position extrême, fixés de façon à ne plus pouvoir se déplacer.
