42mm Underground Friction Bolt Friction Stabilizer For Metal Mine Split Sets

Friction stabilized anchor is a new type of anchor with full-length anchorage and active reinforcement of surrounding rock. It consists of anchor rods and trays. the anchor rod is made of high-strength steel pipe with longitudinal slits. when it is installed in a borehole slightly smaller than the diameter of the pipe, it can immediately exert radial pressure on the entire length of the borehole and prevent the surrounding rock from slipping. together with the supporting force of the pallet, it puts the surrounding rock in a three-way force state and achieves rock stabilization.
