Features
SupAnchor has achieved the security application of 30,000,000 meters self-drilling anchor bar in the world.
The self drilling rock bolt is driven to the required depth by means of rotary percussive drilling.Injection is carried out through hollow rock bolt. Injection mixture flows through the holes at the sacrificial drill bit and automatically stabilizes the drilled hole. Injection ends when the mixture begins to exit from drilled hole. The cement grout is popular used for injection of self-drilling anchor. The usual water-cement ratio ranges from 0,40 to 0,50.
