MF43 series seam pipe anchor

Main specifications of pipe seam anchor, seam pipe anchor, slotted anchor rock friction stabilizer
Length
1. This product has the characteristics of combination of full anchor and end anchor, easy installation and operation, and immediate load-bearing after installation. , mainly suitable for temporary or permanent support of mines, metallurgy, hydropower, railways and other tunnel projects. 1. The working principle and characteristics of the seam pipe anchor. The seam pipe anchor is a new type of anchor with full length anchoring and active reinforcement of the surrounding rock. Its three-dimensional part is a high-strength steel pipe with longitudinal seams. When installed on a pipe with a diameter larger than When drilling a slightly smaller hole, 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, makes the surrounding rock under three-dimensional stress. force state and achieve rock formation greatness. 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 does not lose its supporting resistance. It has better characteristics than the expanding shell anchor.
2. Main performance and specifications of seam pipe anchor
Main technical performance: initial anchoring force ~ ring pull-off load of ton of pipe ~ tensile breaking capacity of ton of anchor pipe ~ corrosion resistance of ton is higher than that of steel ~ , conducive to long-term use.
