Self-drilling rock bolt as soil nail is the drilling, soil nail implantation and grouting three processes completed at once, obviously improve the construction efficiency, in addition to the strata disturbance is very small, but also can be applied to the pre-stressing, is conducive to reducing the displacement of the slope support.
