Sinorock  Self drilling anchors  consist of a fully threaded hollow bar,which serves as drill body with couplers and a drill bit suited to different types of ground conditions.They are recommended in cases where a cased hole is necessary.

Self-drilling Anchors are successfully used for anchoring in poor ground, cohesive and non-cohesive soils, and in the case of unstable boreholes.

The main advantage of self-drilling anchors is their high efficiency, as several operations can be performed at once: drilling, installation of the anchor and sealing/grouting.

Self drilling anchors applications are:

1 Tunneling and Mining

2 Rock bolting

3 Face anchoring

4 Tunnel portals, trenches, and cut and cover area

5 Reinforcement of excavation pits, dams, and slopes - grouted anchors

6 Anchorage of retaining walls and noise barriers
