Application of self drilling rock bolt

rock bolt is an efficient solution for ground anchoring. It can be used in various kinds of ground conditions. Here is the illustration of rock bolts' applications.

Slope stabilization
rock bolt is used to stabilize unstable rock formations. Compared to the traditional methods, the rock bolt is a fast and simpler method of installation. The unconsolidated or weathered ground conditions favor the rock bolt technique.

Foundations with micropiles
Micropiles can be also regarded as drilled piles, composed of injected grout with the rock bolt as steel reinforcement. rock bolt can be installed in sites with limited space. With a light drilling equipment, rock bolt can be installed into most ground conditions including rock. rock bolts are also suitable for tension and compression loads. The big advantage of rock bolt is the combination of drilling and grouting gprocess which makes high piling outputs possible.

Tunneling
rock bolt is the most economical solution for the reinforcement of the tunnel circumference. It is also suitable for advanced roof support for tunnel excavation in overburdened and soft fractured rock conditions.
