Product Description

What is the role of the pole? The following website will introduce relevant content for your reference.

Anchor rod is a member system structure of rock and soil reinforcement.

Through the longitudinal tension of the bolt body, the disadvantage that the tensile capacity of rock and soil mass is far lower than the compressive capacity can be overcome.

On the surface, it limits the separation of rock and soil from the original.

Macroscopically, it increases the cohesiveness of rock and soil mass.

From the mechanical point of view, it mainly improves the cohesion C and internal friction angle of surrounding rock mass φ。

In fact, the anchor bolt is located in the rock soil body and forms a new complex with the rock soil body. The bolt in this complex solves the problem of low tensile capacity of surrounding rock mass. Thus, the bearing capacity of rock and soil mass itself is greatly enhanced.

Bolt is the most basic component of roadway support in contemporary coal mines. It binds the surrounding rock of the roadway together and makes the surrounding rock support itself
