タイトルまたは説明

As an efficient anchoring method, self drilling rock bolt is used in complicated, loose and broken geological condition. Its 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 rock bolt 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 rock bolt system is mainly used for slope stabilization, foundation with micropiles and tunneling, its 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.

Applications

Self-drilling anchor bolt system is mainly used for tunnel and underground engineering, slope engineering, ground and foundation engineering. It can be used for pre-construction support and can effectively enhance the stability of soil and rock mass.

Tunnel and Underground Project

It is mainly used for initial support of tunneling. High pressure grouting is achieved through the hollow bar to strengthen the soil or rock mass to ensure the surface stability. According to the types of support in the tunnel, it can be divided into fore piling, radial support, tunnel-face support, locking the foot support and reinforcement of the tunnel portal.

Slope Stabilization Project

It is mainly used for slope project with poor geological environment. Slope stabilization is ensured by the entire anchoring system itself subjected to tensile and shear forces. It can be used as soil nail support, slope protection barrier, falling rock protection, retaining wall, embankment stability, roadbed reinforcement and other different application scenarios. 

Ground and Foundation Project

It is mainly used for micro pile. Pressure, tension or periodic loads can be transferred to the surrounding soil, transferring structural loads to the underlying foundation structure and limiting the deformation of the building. It can be used as new building pile foundation, existing building structure repair, tower foundation, bridge reinforcement, soundproof wall foundation, protective screen pile foundation, anti-floating pile foundation, retaining beam anchoring and other different structural scenes.

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.
