Brief introduction

Self drilling rock anchor bolt is a bolting solution for unstable ground conditions such as sand, gravel, silt, and clays, and in soft to medium fractured rock formations.

For projects facing above geo-conditions, hollow bar self-drilling anchor should be considered as the main solution cuz it's designed for optimized installation, tailored to the project's needs.

By drilling a hole in collapsing soil or loose lock, with a sacrificial drill bit an a hollow bar, and after the drilling operation injecting cementitious grout or resin into the hollow bar and surrounding cavity, it's a top solution choice.

Advantage

1. Chasing free in the operation

2. Drilling, anchoring, grouting can be done simultaneously

3. Minor space requirement for the accomplishment of anchoring

4. Optimized machinery and manpower requirements

5. Adjustment of the drill bit design and diameter to different rock mass and ground conditions

6.Self drilling anchor bolt has higher bounding stree.
