Self drilling anchor bolt is a new anchoring method, which was introduced from foreign countries and then was improved according to our own characters. It can adapt to different and complex geological and construction conditions. There are several successful examples in railway engineering in China.

Currently, self drilling bolts used in mine timbering are commonly have poor support ability and pre-stress. Because of the horizontal crustal stress, pressure bar destabilizing is easily happened on tunnel roof so that there will be tensile failure, abscission layer and tunnel fall of ground.

Self drilling anchor is irreplaceable in narrow construction environment.

During the constructions of underground 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, self drilling anchor is needed instead of ordinary one. 
Sinorock self-drilling anchor embodies drilling, grouting and anchoring as a whole.Widely used as an efficient anchoring means, in tunnel pre-support, slope, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sink age. It’s irreplaceable in narrow construction environment. 
1. Casing free in the operation. Anchor bar is also a drill pipe which is convenient and time-saving.
2. Drilling and grouting can be done simultaneously. With good grouting spread radius and reliable anchoring quality, fractures can be filled effectively.
3. The anchor bar with standard full thread can be cut according to your requirement. The cut anchor bar can be connected by couplers. It’s suitable in narrow work space.
4. Due to the continuous R-thread and T-thread, self drilling anchor bolt has higher bonding stress.
Nowadays, supporting structures are perfecting gradually and there are many methods to supporting deep foundation. One method is self drilling rock bolt, which is accepted by people increasingly.

Hollow anchor bolt should be adopted on the crown of the tunnel

It is complicated in construction geology for the tunneling,so we should support tunnel with hollow anchor bolt,hollow anchor bolt support is currently the most widely used method for high grade highway& tunnelling, also it is the core of the process.

The Φ25mm hollow anchor bolt should be adopted on the crown of the tunnel. The drilling machine will apply hydraulic descaling system drill rig or the pneumatic drill. After the self-manufactured rack has been prepared, try to drill one self drilling anchor bolt which is 3m long. When drilling, take attention to the adjustment of the water pressure. If there is no problem, drill the self drilling hollow anchor bolt with the same angle. Make records at any time during the drilling process.

After the self drilling hollow anchor bolt reached the designed depth, set the plug into the tail of the drill pipe. Then tighten the nut, block off the hole, and connect the rod end and grouting pipe with the quick coupling. The next step is grouting. Grouting the cement material with BW250 grouting mortar pump until reached the predetermined pressure. Finally, arrange the mudjack and anchorage to make the surrounding rock and hollow anchor bolt form an entirety as soon as possible.
