The friction stabilizer bolt is a new type of anchor of full-length anchoring and active
reinforcement of surrounding rock.
It is composed of an anchor rod and tray.
The anchor rod is made of high-strength steel pipe and has longitudinal slits. When it is installed in a borehole slightly smaller than the pipe diameter, it can immediately apply radial pressure to the borehole through the entire length and prevent the surrounding rock from sliding down. Coupled with the supporting force of the tray, the surrounding rock is in a three-direction stress state to achieve rock stability.
