T40 Self drilling anchor bolt / Self drilling anchor bar / hollow anchor bar

Application:

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.

 

T40 Self drilling anchor bolt / Self drilling anchor bar / hollow anchor bar

Features:

1, Self drilling anchor system has two performances: the one is drilling, the other one is grouting. It features a hollow bore for flushing, or simultaneous drilling and grouting.

2, Self drilling anchor system is reliable, efficient and convenient, which makes high piling output possible.

3, We can also make the Hot-Dip Galvanizing Corrosion Protection according to EN ISO1461
