PRODUCT DETAILS
Introduction
The hollow drill grout anchor rod adopts the empty structure, and the hole in the rod body is used as the high-pressure air water channel and grout channel. Compared with the solid rod, the hollow rod body structure can get better rigidity and shear strength. The outer surface of the bolt has a standard thread made of a large bump. The thread structure is convenient for cutting and connecting the bolt. Compared with the smooth rod body, the binding area between the bolt body and the grout is increased, thereby improving the armature force.
Challenging geological conditions, such as weak surrounding rocks and fault zones, are common in various underground projects, leading to great difficulties for rock anchor construction, especially in the case of severe collapses and the need for long bolts. The bolt is powerless. The hollow trowel bolt series self-absorbs, integrating functions such as drilling, grout and anchoring. It can be used in tunnel advanced support, radial support, and various slope treatment projects. It is very good to improve the surrounding rock and achieve a perfect confirmatory effect.
