Self-drilling hollow anchor system has been used widely as a new technology for slope stabilization.
Self-drilling hollow bar is full threaded, in which system coupler is used to increase the length, and drill bit with different design for different stratum is installed in the front end as drilling forward, with following advantages:
- Highly increased drilling and installation efficiency. Labor cost saved huge.
- Excellent adaption to difficult rock foundation.
