It is widely used as self-drilling ground control solution that is applied to civil engineering and underground construction. The self-drilling rock anchor system is composed of a fully threaded steel bar together with many other accessories. This system can be drilled into rock or collapsing soils without a casing and the grouting can be done simultaneously. Due to this feature the denseness of the grouts is greatly improved and it saves much time, materials and labors.
No matter what a kind of rock mass and ground condition it is, the operation principle is easy and similar. Drilling, anchoring and grouting can be performed in one single operation. In minor space it works also very well. Grouting works synchronize with drilling or after drilling so that the grout can fill fractures effectively.
