The hollow anchor bar of Sinorock is an efficient anchoring method

As an efficient anchoring method, hollow anchor bar is mainly used for slope stabilization, foundation with micropiles and tunneling, it¡¯s also widely used in the railway system, metro project, etc. It can be installed in sites with weak rocks, loose soil, weathered layer, sand with stone layer and so difficult to create a hole in complex formation. The unconsolidated ground condition favor the hollow anchor bar technique for fast and simple method of installed compared to the traditional method. In modern tunnelling, especially in subsidence-sensitive or urban areas, the usage of self-drilling pipe umbrella support is a widely and successfully adapted spacious pre-support system.
As an important form of reinforcement in geotechnical engineering, hollow anchor bar supporting is safe, effective, and economical, etc. Therefore, the hollow anchor bar will have more and more application in the international geotechnical engineering fields.
The broken loose surrounding rock is full of instability. It¡¯s easy to collapse and lead to loose displacement. The pressure is relatively large. Therefore it needs that kind of hollow anchor bar which can support the rock at once after installation, own sufficient prestress and whole-grouted, and even infiltrate surrounding rock fissures.
