Self drilling anchor bolts are widely used as an efficient anchoring means, for drilling, grouting and anchoring in tunnel pre-support, slope anchor, mining, pre-support Micropiles etc.
It is a kind of self drilling anchor. Grout slurry can be erupted out from drill bit, then it can fill surrounding drill hole and stratum fracture. It makes anchor bolt combine with surrounding soil texture, forms concrete column with steel pipe, and then has the effect of reinforcement.
1. It can solve defects that unfilled grouting of traditional mortar anchor bolt during the construction and can’t grouting with pressure.
2. The operation is simple, cost is low, construction is convenient and efficiency is clear.
3. It can realize grouting with pressure and reform foundation surrounding rock conditions.

Self drilling anchor system is mainly used in slope stabilization, tunneling pre-support, foundations with micropiles, it is 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 formations. The unconsolidated ground condition favor the self-drilling anchor bolt technique for fast and simple method of installation compared to the traditional method.
