Sinorock Self drilling anchor system is a great and fast solution for rock anchoring. Sinorock self drilling anchor bolt is suitable for broken rock, loose soil and conditions which are difficult to drill holes, such as fracture zones, decayed rock, gravel, sandy gravel, backfill ground.It can be used in different complicated conditions. Here is the some details:

Tunneling 

The Sinorock self-drilling anchor system are part of the excavation process and serve as primary soil/rock support for:

1 Radial consolidation of the tunnel circumference supports the rock, forming a load bearing ring thus enabling the rock supporting itself (together with shotcreate and other facing elements).

2 Umbrellas and Fore poling as pre-support in poor rock formation, shallow overburden and critical stress conditions.

3 Face stabilization to sustain rock pressure for excavation with large cross sections.

4 Root piles to divert stress. 

Slope stabilization

Self drilling anchor system is used to stabilize unstable rock formations. The unconsolidated or weathered ground conditions favor the SDA technique for fast and simple method installation compared to the traditional methods.

Foundations with micropiles

Micropiles can be defined as drilled piles, composed of injected grout with the hollow bar system as steel reinforcement. Self drilling anchor system can be installed in sites with limited space using light drilling equipment. Self drilling anchor system also can be installed into most ground conditions including rock and are suitable for tension and compression loads. Self drilling anchor system combines drilling and grouting making high piling outputs possible. It is the advantage.
