Abstract

La présente invention concerne un boulon de renfort pour roche (1) qui comporte : une partie de boulon extensible tubulaire (2) avec une section transversale fermée pour l'extension à l'intérieur d'un trou de forage (8), la partie de boulon extensible tubulaire (2) possédant une extension longitudinale, une partie de raccordement (3) pour le raccordement à une source de pression à une partie intérieure de la partie de boulon extensible tubulaire, et une partie de support (4, 13) pour le support contre une face de roche (12) dans la région d'une embouchure du trou de forage. Au moins un manchon de protection (5, 5a, 5b) est agencé sur une partie extérieure de la partie de boulon extensible tubulaire (2), et chaque manchon de protection (5, 5a, 5b) est déplaçable le long de l'extension de la partie de boulon extensible tubulaire (2) et est fixable sur celle-ci dans une position longitudinale choisie sur la partie de boulon extensible tubulaire. La présente invention concerne également un procédé pour installer un boulon de renfort pour roche (1) et un manchon de protection.
