Abstract

Un dispositif de renforcement d'un mur en béton comprend un siège de montage et un assemblage de capsule comprenant un ajutage d'injection, une capsule en forme de soufflet remplie d'agent de renforcement, un ressort hélicoïdal servant à exprimer la capsule, une enveloppe, un capuchon avant et un capuchon arrière. Le dispositif comprend en variante un capuchon arrière possédant un trou à travers lequel est introduite une tige creuse pour comprimer le ressort hélicoïdal en le tirant en arrière. Un procédé de renforcement d'une paroi en béton consiste à fixer le siège de montage sur la fissure de la paroi, à monter l'assemblage de capsule sur le siège de montage et à exprimer la capsule. Ce procédé consiste de préférence à percer un trou dans la paroi en béton, à y introduire un tampon à injection dilatable, et à monter l'assemblage de capsule sur le tampon pour réparer une fissure provoquée par la séparation de la couche de mortier.
