split set rock bolt overview
Pipe slit anchor is a full-length anchoring, active reinforcement of the surrounding rock of the new type of anchor, its three-dimensional part is a longitudinal slit of high-strength steel pipe, when installed in slightly smaller than the diameter of the pipe drilling holes, it can be immediately in the full-length range of the radial pressure on the hole wall and stop the friction of the surrounding rock sliding down, coupled with the bearing force of the anchor pallet tray plate, so as to make the surrounding rock in the three-way force state, and to achieve the rock layer great. In the case of blasting vibration surrounding rock anchor shift, etc., there is a significant increase in the late anchoring force, when the surrounding rock is significantly displaced, the anchor does not lose its support resistance, it has better characteristics than the rising shell type anchor.

friction bolt Working principle
friction bolt Working principle
When a slit anchor is installed in a hole smaller than the diameter of the pipe, three forces are exerted on the surrounding rock: radial pressure on the hole wall over the full length of the slit anchor, friction to stop the surrounding rock from sliding down the hole, and the bearing force of the slit anchor pallet, which makes the surrounding rock more stable.
