Patent

CA 2456583

In one aspect, the present invention provides a stabiliser for stabilising earth, rock or other structures, the stabiliser having a hollow elongate body portion including an opening extending substantially the entire length of the body portion and a closure member aligned to substantially cover the opening of the body portion, the closure member being configured to extend substantially parallel to an inner wall of the body portion in the vicinity of the opening. The present invention also provides a stabiliser assembly including: a stabiliser for stabilising earth, rock or other structures, the stabiliser having an elongate body portion including an opening extending substantially the entire length of the body portion; a closure member aligned to substantially cover the opening of the body portion; and a cartridge containing filler material in a bag of permeable material, the bag being shaped to substantially conform to the internal dimensions of the stabiliser body; wherein the closure member substantially covering the opening of the body portion significantly reduces the likelihood of a cartridge becoming ensnared upon the internal wall of a hole during insertion of the stabiliser assembly into a hole.

Selon un aspect, l'invention concerne un stabilisateur servant à stabiliser la terre, la roche ou d'autres structures, ce stabilisateur comportant une partie corps allongé creuse comprenant une ouverture qui s'étend sensiblement sur toute la longueur de la partie corps et un élément de fermeture aligné servant à recouvrir sensiblement l'ouverture de la partie corps, cet élément de fermeture étant configuré pour s'étendre de manière sensiblement parallèle à une paroi intérieure de la partie corps, à proximité de l'ouverture. L'invention concerne également un ensemble stabilisateur comprenant: un stabilisateur servant à stabiliser la terre, la roche ou d'autres structures, ce stabilisateur comportant une partie corps allongé comprenant une ouverture qui s'étend sensiblement sur toute la longueur de la partie corps; un élément de fermeture aligné servant à recouvrir sensiblement l'ouverture de la partie corps; et une cartouche contenant un matériau de remplissage dans un sac en matière perméable, ce sac se conformant sensiblement aux dimensions intérieures du corps du stabilisateur. L'élément de fermeture recouvrant sensiblement l'ouverture de la partie corps permet de réduire sensiblement la probabilité que la cartouche se retrouve bloquée sur la paroi intérieure d'un trou lors de l'insertion du stabilisateur dans le trou.
