What is rock bolt?
Bolt or rock anchor is the most basic component of mine roadway support. It plays a very important role in strengthening the surrounding rock of mines and tunnels, which enables the surrounding rock to support itself and prevent rock displacement. Now high-strength bolts are not only used in mines, but also in engineering technology to strengthen the main body of slopes, tunnels, DAMS, and in some applications are called soil nails or ground anchors. Rock bolt is a tension member deep into the rock or soil, one end is connected with the engineering structure, the other end is inserted into the stratum.
The bolt body can be divided into free section and anchor section. In the free section, the tension of the bolt head is transferred to the anchoring section, and the prestress is applied to the bolt. The anchoring section refers to the area where the cement slurry binds the prestressed reinforcement to the soil layer. Its function is to increase the bonding friction between the anchor rod and the soil layer, increase the anchoring pressure of the anchor rod, and transfer the tension of the free section to the depth. The soil.
