Product Description
We are the High Strength Rock Bolt Manufacturer
Main Components:
Self-drilling Anchor System Consists of five basic components:
- One Or More Steel Hollow Bar
- One Or More Extension Coupling To Connect The Hollow Bars
- A Steel Plate
- A Steel Nut
-A Sacrificial Drill Bit
- One Or More Steel Hollow Bar
- One Or More Extension Coupling To Connect The Hollow Bars
- A Steel Plate
- A Steel Nut
-A Sacrificial Drill Bit
The self-drilling hollow anchor system performs drilling, anchoring and grouting in one step. It allows air and water to freely pass through the bar during drilling to remove debris and then allows the grout to be injected immediately after completely covering the entire bolt.
Features and Advantages
No predrilling
Rock at any depth
Can be installed in all soil types
Casing for lateral loads
Grout and bar are installed simultaneously
Only need rock drill & grout plant
