What Is A Slotted Anchor Rod

Pipe joint anchor rod is a new type of anchor rod that is fully anchored and actively strengthens the surrounding rock. Its three-dimensional part is a high-strength steel pipe with longitudinal joints. When installed in a borehole slightly smaller than the pipe diameter, it can immediately apply radial pressure on the hole wall and prevent the sliding of the surrounding rock within the full length range. In addition, the support force of the anchor rod tray support plate can make the surrounding rock in a three-dimensional stress state and achieve rock stability. Under the conditions of blasting vibration, surrounding rock anchoring, etc., the anchoring force increases significantly in the later stage. When the surrounding rock undergoes significant displacement, the anchor rod does not lose its support resistance, and it has better characteristics than the expansion shell anchor rod.
