Patent

CA 2228365

This invention relates to a friction rock stabilizer which comprises an elongated tendon tube which is reduced in cross-sectional dimension over a portion of its length towards one end of the tube, a slot which extends over at least the unreduced length of the tube and a radially extending stop which is located on the reduced dimension portion of the tube for supporting a face washer on the stabilizer. Preferably, the reduced cross-sectional length of the tube is parallel sided and is conveniently circular in cross-section.

La présente invention a trait à un dispositif de stabilisation du roc par friction qui comprend un tube allongé tendu dont la section transversale est réduite sur une partie de sa longueur vers une extrémité, une fente qui s'étend sur au moins la longueur non comprimée du tube et une butée s'étendant radialement qui se trouve sur la partie du tube dont la section a été réduite afin de supporter une rondelle à collerette sur le dispositif de stabilisation. De préférence, la longueur de la section transversale réduite du tube comporte des côtés parallèles et possède, ce qui est pratique, une section circulaire.
