Product Description
Self-Drilling Anchor System for Slope Engineering
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. This innovative system combines drilling and grouting in a single operation for enhanced productivity in slope stabilization projects.
System Components
- Hollow anchor bolt with integrated drill bit
- Anchor nut and bearing plate assembly
- Anchor couplers for extended lengths
- Centralizers for proper alignment
Operation Process
The system drills through collapsing soil or loose rock using the hollow bar and drill bit, then injects grout through the hollow bar into the surrounding cavity. This simultaneous drilling and grouting process ensures maximum efficiency and structural integrity.
