As an efficient anchoring method, self drilling rock bolt 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 anchor system 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 anchor bolt 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 favor the self drilling anchor bolt technique for fast and simple method of installed compared to the traditional method. 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.
