Working Principle
The diameter of the drilled hole is slightly smaller than the outer diameter of the rod (e.g., rod φ47mm, hole φ45mm).
The impact of the air drill pushes the rod into the hole, and the open-ended pipe is compressed, generating radial expansion pressure on the hole wall.
Full-length contact, relying on frictional force to provide initial anchoring force (immediate bearing capacity); when the surrounding rock moves, the frictional force increases with pressure, adapting to large deformation surrounding rock.
Common Specifications
Outer diameter: 33/39/42/47mm (most commonly φ47).
Length: 1.2/1.5/1.8/2.0/2.4m.
Support tray: 150×150×10mm (square), φ150×10mm (round), butterfly shape.
Main Features
✅ Immediate Bearing Capacity: Installation immediately provides initial anchoring force, no need to wait for the anchoring agent to set.
✅ Full-length Anchoring: The entire rod body is in contact with the surrounding rock, with uniform force distribution.
✅ Stretchable: Does not break when the surrounding rock undergoes large deformation, continuously providing resistance.
✅ Efficient Installation: Direct impact installation with an air drill, 1 person / 1 minute / rod, no need for grouting.
✅ Low Cost: Cheaper than resin anchors, suitable for soft rock, fractured surrounding rock, and large deformation roadways.
