R38N Rock And Mining Self Drilling Anchor Bolt
The Self
Drilling Anchor (SDA) system is a bolting solution for difficult ground and rock
conditions. The system enables drilling and grouting in one
operation, making much saving in jobsite and project time. Which is
comprised of a hollow threaded anchor bar with a sacrificial drill
bit that performs drilling, anchoring and grouting in a single
operation. Self drilling anchor system is mainly used in slope
stabilization, tunneling pre-support, foundations with micro piles
etc jobs, which is widely used in mining, tunneling, railway, metro
construction etc projects.
Applications
Tunnelling Ground engineering
1. Face stabilization
2. Radial systematic anchoring
3. Foundation for avalanche protect
4. Stabilization of tunnel portals
5. Spilling
6. Root piling
