The invention discloses a supporting and connecting stick for anchor rod production. The supporting and connecting stick for the anchor rod production comprises a top hole, a lining and a taper-shank, wherein the taper-shank is used for being connected with other components in a taper mode. The support and connecting stick for the anchor rod production is made of high-carbon steel, so that the supporting and connecting stick for the anchor rod production is high in quenching hardness, good in strength, strong in anti-impact force and suitable for the anchor rod production.
Description
Technical field [0001] The invention relates to a bearing rod, in particular to a bearing rod used for anchor rod production. Background technique [0002] With the increase in the construction of transportation, energy and other infrastructure facilities, in tunnels, basements and slopes, the anchoring technology that can give full play to the self-stability of the rock mass has been rapidly developed. The amount of rock bolts is increasing day by day, showing a broad Prospects. Bolt support is the most economical and effective method to improve the stability of geotechnical engineering. [0003] Among them, the quality of the hollow anchor rod is reliable, the anchoring effect and the reinforcement effect are far superior, and its application is more and more extensive. The hollow bolt system can ensure full grouting between the bolt body and the hole wall, and give full play to the anchoring effect of the bolt. It can provide supporting force (supporting force or prestress) i...
