Abstract

Dispositif de cintres semi-rigides pour le soutènement des galeries souterraines, pouvant être mis fortement en serrage dès la pose. Il est constitué de cintres en 3 ou 4 éléments, curvilignes en leur partie médiane, de profilés non aboutés et reliés par des tôles d'assemblage en forme d'oméga reliées par des boulons. Ces tôles sont conformées de maniere à permettre l'introduction, entre les extrémités de deux éléments, des ergots d'un vérin hydraulique amovible dont l'action rattrape le jeu entre la couronne du cintre et le terrain, donnant au soutènement dès la pose un serrage important et par suite une efficacité immédiate. Application notamment à tous les cintres en profilés H.
