Description

R38N SDA Hollow Grouted Self Drilling Anchors Rock Bolt For Slope Protection

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.

Application:

Self drilling anchor system is mainly used in slope stabilization, tunneling pre-support, foundations with micropiles, it is also widely used in the railway system, metro project etc. It can be installed in sites with weak rocks, loose soil, weathered layer, sand with stone layer and so difficult to create a hole in complex formations. The unconsolidated ground condition favor the self-drilling anchor bolt technique for fast and simple method of installation compared to the traditional method.

Features and Advantages

• Particularly suitable for difficult ground conditions.

• A high rate of installation since drilling, placing and grouting can be performed in one single operation.

• Self drilling system eliminates the requirement for a cased borehole.

• Installation with simultaneous drilling and grouting possible.

• Easy installation in all directions, also upwards.

• Suitable for working in limited space, height and in areas of difficult access.

• Simple post grouting system.

• Hot-dipped galvanizing for corrosion protection
