Choose Yize for good quality. Weifang Yize Industry and Trade Co., Ltd. specializes in the production of various mining anchors, focusing on the production of pipe-slit anchors. Hello everyone, I am salesperson Zhou Zihan. Now I will introduce to you the uses, specifications, models, characteristics and usage methods of pipe-slit anchors

Pipe-slit anchors
Anchors
It is a new type of full-length anchor that actively reinforces the surrounding rock. Its three-dimensional part is a high-strength steel pipe with longitudinal slits. When installed in a borehole slightly smaller than the pipe diameter, it can be immediately The radial pressure is applied to the hole wall throughout the entire length and the friction force that prevents the surrounding rock from sliding down, coupled with the supporting force of the anchor pallet, puts the surrounding rock in a three-way stressed state and achieves greatness of the rock formation. In the case of blasting vibration and anchorage movement of the surrounding rock, the anchoring force
will increase significantly in the later period. When the surrounding rock undergoes significant displacement, the anchor will not lose its support
Resistance
