Product Description
Self-Drilling Anchor System for Slope Stability
Self-drilling anchor bolts provide an efficient bolting solution for unstable ground conditions including sand, gravel, silt, clay, and soft to medium fractured rock formations. The system combines drilling and grouting operations in a single process for enhanced productivity and reliability.
System Components
- Hollow anchor bolt with threaded connections
- Anchor nut and plate assembly
- Anchor coupler for extended lengths
- Drill bit for various ground conditions
- Centralizer for proper grout distribution
The self-drilling process involves drilling through collapsing soil or loose rock using the hollow bar and drill bit, followed by grout injection through the hollow bar to create a reinforced anchor system.
