friction bolt/split set rock bolt Product Details
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 prevent the surrounding rock sliding friction, coupled with the support 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.
What are the technical characteristics of friction bolt/split set rock bolt?
the raw material is made of high-strength alloy strip steel
easy to install
no anchoring agent is needed
the friction between the anchor rod and the rock body is high
it has high alkali and tensile strength
it is equipped with high-strength pallet, and the pallet is subjected to uniform force
the height of the roadway is greater than the length of the anchor rod
