T Thread Self-drilling Hollow Bar System

As an efficient anchoring method, self-drilling hollow bar is used in complicated, loose and broken geological condition. It’s widely applied to pre-support project, radial support project, slope stabilization, foundation support project, roadway support project, soil nail wall, back pull anchor rod retaining wall and other rock supporting work.

Functions:Self-drilling hollow bar is an advanced system which can ensure the anchoring effect for complex ground conditions. It can be integrated with the functions of drilling, grouting and anchoring.Conditions:Self-drilling hollow bar system 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 favors the self-drilling hollow bar technique for fast and simple method of installed compared to the traditional method.Cases:Features and advantages:1. It features a hollow bore for flushing, or simultaneous drilling and grouting.2. Reliable, Efficient and Convenient.3. Choice of drill bits for different ground conditions.4. It can be elongated by using couplers.5. Suitable for anchoring in broken geological condition and narrow space, which has achieved perfect effect.Construction Process:
