Technology process
1. Connect the alloy drill and anchor rod one end, on the other end, connect the drill sleeve and shank adapter , then connect the drilling rig or hand-held drill. Then start drilling, fill the cooling water while drilling.( if you want to lengthen the anchor rod, can connect the coupling, and then drilling)
2. Take down the drill, put the stop-grouting plug into the rod, and insert it to the hole, then ready to grout. Special circumstances like surrounding rock grouting tension is over or surrounding rock is too broken, can use anchor agent to seal the hole.
3. Connect quick grouting coupling and anchor rod end, connect other end of grouting machine.
4. Start grouting, when grouting full and reach design value then power off . Grouting pressure according to the design parameters and grouting machine performance determine , cement/sand reference values is 1:0 ~ 1:1, water/cement reference value is 0.45:1 ~ 0.5:1.
5. Install anchor plate and nuts, and tighten nuts.

As an efficient anchoring method, self drilling rock bolt is used in complicated, loose and broken geological condition. It�¢??s widely applied to pre-support project, radial support project, slope stabilization, foundation support project, roadway support project, soil nail wall, back pull anchor rod retaining wall and other rock supporting work.

Functions:
Self drilling anchor 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.

Conditions:
Self drilling anchor bolt system is mainly used for slope stabilization, foundation with micropiles and tunneling, it�¢??s also widely used in the railway system, metro project, etc. It can be installed in sites with weak rocks, loose soil, weathered layer, sand with stone layer and so difficult to create a hole in complex formation. The unconsolidated ground condition favor the self drilling anchor bolt technique for fast and simple method of installed compared to the traditional method.

Features and advantages:
1. It features a hollow bore for flushing, or simultaneous drilling and grouting.
2. Reliable, Efficient and Convenient.
3. Choice of drill bits for different ground conditions.
4. It can be elongated by using couplers.
5. Suitable for anchoring in broken geological condition and narrow space, which has achieved perfect effect.

Rock bolts are commonly used in civil engineering and mining to reinforce and stabilize
rock masses. A rod or bar is inserted into a drilled hole, which is then grouted in place using
cement or resin. FRP Rock bolts withstand tensile forces and evenly distribute load,
eventually increasing overall strength. They control rock movements, reduce deformation
and prevent collapses.
