Description
technical field [0001] The invention relates to a bushing, in particular to a bushing used in the production process of anchor rods. Background technique [0002] With the intensification of infrastructure construction such as transportation and energy, in tunnels, basements and slopes, as an anchoring technology that can give full play to the self-stabilization ability of rock mass, it has developed rapidly, and the amount of rock anchors is increasing day by day, showing a broad potential. Prospects. Bolting is the most economical and effective method to improve the stability of geotechnical engineering. [0003] Among them, the quality of the hollow anchor is reliable, and the anchoring effect and reinforcement effect are far superior, and its application is becoming more and more extensive. The hollow bolt system can ensure that the grouting between the bolt body and the hole wall is full, and give full play to the anchoring effect of the bolt. Immediately after the e...
