The bolt body of the hollow bolt adopts a hollow design, and the hole in the rod body is used as the drilling high-pressure air-water channel and grouting channel. Compared with the solid rod body, the hollow rod body design can obtain better rigidity and shear strength. The outer surface of the bolt has a standard large-pitch thread structure. The thread structure is convenient for cutting and connecting the bolt. Compared with the smooth rod body, the bonding area between the bolt body and the grouting material is increased, thereby improving the anchoring force.
structure
It is composed of steel expanding shell anchor head, hollow grouting bolt body, grouting stopper, backing plate and nut.
The bolt is the most basic component of roadway support in contemporary coal mines. It reinforces the surrounding rock of the roadway, so that the surrounding rock supports itself. Bolts are not only used in mines, but also in engineering technology to reinforce the main body of slopes, tunnels and dams. The bolt is a tension member that goes deep into the stratum. One end of the bolt is connected to the engineering structure, and the other end is deep into the stratum. The whole bolt is divided into a free section and an anchoring section. area, whose function is to prestress the bolt.
effect
1. Anchor is a bar system for rock and soil reinforcement.
2. Through the longitudinal tensile force of the bolt body, it overcomes the disadvantage that the tensile capacity of the rock and soil mass is far lower than the compressive capacity.
3. On the surface, it limits the separation of the rock and soil mass from the original body.
4. Macroscopically, it increases the cohesion of rock and soil.
5. From the point of view of mechanics, it mainly improves the cohesion C and the internal friction angle φ of the surrounding rock mass.
6. In essence, the bolt is located in the rock and soil to form a new complex with the rock and soil. The bolts in this complex are the key to solving the low tensile capacity of the rock mass. Therefore, the bearing capacity of the rock mass itself is greatly enhanced.
8. The bolt is the most basic component of roadway support in contemporary underground mining mines. It binds the surrounding rock of the roadway together, so that the surrounding rock supports itself.
9. Bolts are not only used in mines, but also in engineering technology to actively reinforce slopes, tunnels, dams, etc.
