Pipe seam anchors are highly specialized support supplies and are used for underground culvert roofs and other engineering supports. The advanced materials used have simple manufacturing processes and are easy to use. They have strong anchoring force, high tensile strength and strong expansion force in underground anchor and shotcrete support, making the entire roof integrated.
Working principle and characteristics The pipe-slit anchor is a new type of full-length anchor that actively reinforces the surrounding rock. The three-dimensional part of the pipe-slit anchor is a longitudinally slit high-strength steel pipe. When installed on When drilling a hole slightly smaller than the pipe diameter, radial pressure can be immediately applied to the hole wall throughout the entire length and the friction force to prevent the surrounding rock from sliding down, coupled with the supporting force of the anchor pallet, can keep the surrounding rock in a Three-way force state, and achieve rock formation greatness.
The anchoring force of the pipe-slit anchor will be significantly increased in the later period when the surrounding rock is anchored due to blasting vibration. When the surrounding rock is significantly displaced, the anchor will not lose its supporting resistance. It is better than the shell expansion. Type anchors have better characteristics.
