Product Description
R38 Self-Drilling Anchor System Overview
Self-drilling anchor bolts provide an efficient bolting solution for challenging ground conditions including sand, gravel, silt, clay, and soft to medium fractured rock formations.
System Components
The complete self-drilling anchor 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 assembly. Following drilling completion, grout is injected through the hollow bar into the surrounding cavity, creating a highly productive anchoring solution.
