R25N Full Thread Steel Hollow Self Drilling Anchor Bolt System
The Self-Drilling Anchor (SDA) System is an advanced anchoring solution engineered for tunneling and ground engineering applications. This innovative system combines drilling, anchoring, and grouting into a single continuous operation, delivering enhanced safety, speed, and reliability in challenging ground conditions.
How the Self-Drilling Anchor System Works
During the drilling process, the hollow anchor bar facilitates the free passage of air and water, effectively removing debris from the borehole. Once the target depth is reached, grout can be immediately injected through the same hollow bar, ensuring complete encapsulation of the entire bolt in one efficient step.
Key System Features
  • Optimized for difficult ground conditions including loose, fractured, or water-bearing soils
  • High-speed installation: drilling, placement, and grouting completed in one operation
  • No casing required - hollow bar serves as both drill rod and permanent anchor
  • Capable of simultaneous drilling and grouting operations
  • Flexible installation in any direction, including upward applications
  • Ideal for confined spaces, low overhead areas, and hard-to-reach locations
  • Simple post-grouting capability for enhanced performance
