During the construction of undergroud works, it is very common to encounter soft rock, fractured zone and large deformation due to high ground stress. In the case of serious collapsing, extra-long anchor is needed instead of ordinary one.

Technology Process
The Self Drilling Anchor system is comprised of a hollow threaded anchor bar with a sacrificial drill bit that performs drilling, anchoring and grouting in a single operation. Self drilling anchor system is mainly used in slope stabilization, tunneling pre-support, foundations with micro piles etc projects.
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.
Packaging And Transportation
The packaging is packaged in tarpaulins and wooden boxes to ensure that it will not rust and corrode in the process of encountering water.
