R Thread Self-drilling Anchor Bolt
Introduction:
Self drilling anchor bolt combines drilling, grouting and anchoring together. It ensures the anchoring effect in complex ground conditions. It's safe, reliable, and efficient.
Application:
1. R thread self drilling anchor bolt is suitable for broken rock, loose soil and conditions which are difficult to drill holes, such as fracture zones, decayed rock, gravel, sandy gravel, backfill ground.
3. In slope stabilization, rock bolts and soil nails can be used to maintain and strengthen soil and rock.
4. Used as micropile reinforcement. Micro pile can transmit structural load to foundation, and then limit the deformation of buildings.
5. Drill bits can be used for differently according to the rock conditions.
Features:
1. Casing free in the operation. Anchor bar is also a drill pipe which is convenient and time-saving.
2. Drilling and grouting can be done simultaneously. With good grouting spread radius and reliable anchoring quality, fractures can be filled effectively.
3. The anchor bar with standard full thread can be cut according to your requirement. The cut anchor bars can be connected by couplers. It’s suitable in narrow work space.
4. Due to the continuous R-thread and T-thread, self drilling anchor bolt has higher bonding stress.
