Description

73mm Outside Diameter Threaded SDA T73/35 Self Drilling Hollow Grout Rock Bolts

Features

SupAnchor has achieved the security application of 30,000,000 meters self-drilling anchor bar in the world. The self drilling system enables drilling and grouting in one operation, making much saving in jobsite and project time.

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.

Applications

1. Ground piling

2. Slope stabilization

3. Radial systematic anchoring

4. Foundation

5. Spilling

6. Tunneling
