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:Features and advantages:
1. Hollow design realizes the function of grouting pipe and avoids the loss of mortar caused by the traditional grouting pipe.
2. Grouting is full, and pressure grouting can be realized to improve the quality of the project.
3. Neutrality is good, the mortar can wrap the entire length of the anchor body to avoid rust and achieve long-term support.
4. It is easy to install, and it is convenient to install the plate and nut without machining the thread on site.
Application:
The hollow bar anchor has been successfully applied in rock and soil anchoring engineering such as tunnel construction, slope treatment, foundation pit retaining wall and mining, and has achieved good economic benefits
