T127 Anchor Bolt

• Brief Introduction
T127 anchor bolt is one of the T-thread self-drilling hollow injection anchor bolt. It is very common for underground works to encounter soft surrounding rock, fractured zone and great deformation due to high ground stress. It is difficult for anchor work, especially under the condition that serious hole collapsing occurs and extra-long bolt is needed, while it is impossible to solve the problem with ordinary bolt. This self-drilling bolt embodies drilling, grouting and anchoring as a whole and can improve the condition of surrounding rock in the course of deformation due to high ground stress.
