Product Description

The product is composed by hollow anchor bar, anchor nut, anchor plate, anchor coupler, drill bit, and the hollow anchor bars can be cut and lengthened by coupling on request. It is unique anchoring system and can meet current and increasing demands of the tunneling industry and ground engineering. The system provides advantages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil.

Advantages︰Features
1. Safe, reliable, and time saving. Self drilling system eliminates the requirement for a cased borehole.
2. Simple installation & operation.
3. Choice of drill bits for different ground conditions.
4. Grouting works synchronize with drilling or after drilling. Grout can fill fractures effectively. 
5. Anchor bars can be cut and lengthened on request, applying to narrow spaces.
6. It provides higher bonding stress than smooth steel pipe depending on continuous wave thread.
Application
Radial bolting 
Slope stabilization 
Fore poling 
Micropile
