Product Description
Self Drilling Anchor System R32 Anchor Bar
Self Drilling Anchor Bolts provide reliable bolting solutions for challenging ground conditions including sand, gravel, silt, clay, and soft to medium fractured rock formations. This innovative system combines drilling and anchoring in a single operation for enhanced productivity.
System Components
The complete self-drilling anchor system includes:
- Hollow anchor bolt
- Anchor nut
- Anchor plate
- Anchor coupler
- Drill bit
- Centralizer
Operating Principle
The system drills holes in collapsing soil or loose rock using an efficient hollow bar and drill bit. After drilling, grout is injected through the hollow bar into the surrounding cavity, creating a robust anchoring solution that significantly improves productivity in underground engineering projects.
