Product Description
R51 Self Drilling Anchor Bolt System
Product Overview
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 anchoring in a single operation for enhanced productivity.
System Components
The complete self-drilling anchor bolt system includes:
- Hollow anchor bolt
- Anchor nut
- Anchor plate
- Anchor coupler
- Drill bit
- Centralizer
Installation Process
The system operates by drilling directly into collapsing soil or loose rock using the hollow bar and drill bit. Following drilling completion, grout is injected through the hollow bar into the surrounding cavity, creating a secure and permanent anchoring solution.
