MAXDRILL Self-drilling Rock Bolt/ rock anchoring

rock bolt use as an efficient anchoring means, in tunnel pre-support, slope stabilization , coast, mine, water conservancy

Structure of self-drilling bolt

It is very common for underground works to encounter soft surrounding rock,fractured zone and great deformation due to high ground stress.This makes it different for anchor work ,especially under the condition that serious hole collapse occurs and extra-long anchor is needed,and it is impossible to solve the problem with ordinary anchor.While maxdrill self-drilling anchor embodies drilling,grouting and anchoring as a whole and can improve the condition of surrounding rock in the couree of deformation due to high ground stress.
