Product Description

Product Description

         Pipe joint anchor rod is a new type of anchor rod that is fully anchored and actively strengthens the surrounding rock. The three-dimensional part of the pipe joint anchor rod It is a high-strength steel pipe with longitudinal slits, which can be installed in a hole slightly smaller than the diameter of the pipe and immediately extend the entire length Apply radial pressure to the hole wall within the range and prevent the frictional force of the surrounding rock from sliding, plus the support of the anchor rod tray support plate By exerting force, the surrounding rock is placed in a three-dimensional stress state, and the greatness of the rock layer is achieved. Pipe slot anchor rod in blasting vibration When the surrounding rock is anchored, the anchoring force increases significantly in the later stage. When the surrounding rock undergoes significant displacement, the anchor rod does not Losing its support resistance, it has better characteristics than the expansion shell anchor rod.
