Broaching burst of anti-rock bolt

The present invention relates to a broaching rock burst of anti-bolt comprising a nut and an anchor pole observed anti-rock burst apparatus, said apparatus comprising an anti-rock burst broaching body and a sleeve, the sleeve and the outer wall of the left end of the anchor nut connection, the right end is connected with sealing sleeve nut, the inner sleeve, from left to right threaded section, a tapered section disposed broaches, cutting guide section receiving the threaded bolt with a closed connecting segment, the accommodating the guide section is provided with cutting flutes and radial guide grooves; broaching knife bar includes a left end disposed within the wear sleeve outer wall of the left end of the shank circumferentially distributed broach and a guide key the broach with flutes corresponding to the guide grooves with the guide key corresponding to the observation end pole through the closure is bolted to the shank. The anchor structure is simple, safe, easy to manufacture, can instantly generate a large deformation, it is possible to provide continuous constant deformation resistance, resistance to high impact capacity, high reliability.
