R38 Self-Drilling Anchor Bolt 38mm Outer Diameter with 500kN Ultimate Load for Soil Nailing Foundation 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. These specialized anchors combine drilling and grouting operations into a single process for enhanced productivity in foundation engineering applications.
- Hollow anchor bolt with integrated threads
- Anchor nut and plate assembly
- Anchor coupler for extension capability
- Drill bit for efficient penetration
- Centralizer for proper alignment
The self-drilling system operates by drilling directly into collapsing soil or loose rock formations using the hollow bar and drill bit. Following drilling completion, grout is injected through the hollow bar into the surrounding cavity, creating a reinforced anchoring system that stabilizes the ground structure.
