CA 2682332

The invention is a rock bolt for being grouted in a borehole, said rock bolt comprising:- an elongate cylindrical massive stem (1) comprising extensive lengths of stem portions (1s) separated by integrated anchors (2) distributed with separations (L3) along the length of said stem (1), - said anchors (2) for being locally anchored relative to their local borehole wall portions for taking up load arising due to rock deformation, - said stem portions (1s) arranged for slipping relative to the grout or the borehole, so as for each of said stems (1s) to take up local elongation strain between pairs of a locally anchored preceding anchor (2a, 2b,...) and a locally anchored consecutive anchor (2b, 2c,...).

L'invention porte sur un boulon d'ancrage qui peut être scellé dans un trou de mine, ledit boulon d'ancrage comprenant : une tige massive cylindrique allongée (1) comprenant des longueurs extensibles de parties de tige (1s) séparées par des ancres intégrées (2) réparties avec des séparations (L3) sur la longueur de ladite tige (1), lesdites ancres pour être ancrées localement relativement à leurs parties locales de paroi de trou de mine pour absorber la charge résultant de la déformation rocheuse. Lesdites parties de tige (1s) sont conçues pour glisser par rapport au scellement ou au trou de mine de sorte que chacune desdites tiges (1s) absorbe la contrainte d'allongement locale entre les paires d'ancres constituées d'une précédente ancre ancrée localement (2a, 2b, ~) et d'une ancre suivante ancrée localement (2b, 2c, ~).
