Abstract

Cette invention concerne un appareil soutènement conçu pour supporter une masse rocheuse, comprenant un élément de support allongé, un collier allongé et des moyens d'ancrage localisé. Les moyens d'ancrage localisé sont conçus pour retenir sensiblement l'appareil à l'intérieur d'un trou de forage formé à l'intérieur de la masse rocheuse. Le collier allongé comprend une lumière qui accueille l'élément de support allongé et il comprend en outre un ensemble bride qui, au moins en partie, vient sensiblement en butée contre une face rocheuse de la masse rocheuse. En cours d'utilisation, un déplacement de la masse rocheuse entraîne le collier allongé à se déplacer, au moins en partie, le long de l'élément de support allongé, ce qui permet à l'appareil de se plier et de contrôler le déplacement de la masse rocheuse.
