In tunnel construction, efficient supporting technology is a key problem. Self drilling rock bolt is an advanced rock bolt system, which combines drilling, grouting and anchoring together. It can solve collapse problem when drilling and it can guarantee grouting effect in complex conditions.

 Compared with common rock bolt, self drilling rock bolt has advantages on anti-bending, shearing resistance and surface adhesiveness. It also can be cut, linked, pre-stressed and released load, etc.
