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.  Self drilling anchoring system is an advanced system which can ensure the anchoring effect for complex ground conditions. It can be integrated with the functions of drilling, grouting and anchoring.  It can be used in railway system, metro project and infrastructure . As an efficient anchoring method, it's also widely used for pre-support, radial support, slope stabilization, foundation support , soil nail, retaining wall, etc.
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
Railway System
Metro Project
Slope Stabilization
Hydroelectric Station
Infrastructure
Mining
Drill bits, nut, plate and coupler, etc.will be accembled accordingly.

Advantages︰ 1. Hollow design, implementation of the grouting tube function, avoid the 
traditional grouting tube pulled out of the mortar caused by the loss. 
2. Grouting full, and can achieve the pressure grouting to improve project 
quality. 
3. Center is good, mortar bolt body length can be wrapped, to avoid corrosion, 
to supporting the long-term purposes. 
4. Easy installation, without on-site processing of threads, it can be easily 
installed an plate, nuts.
