Products Description
split set
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 diameter of the pipe, it can immediately apply radial pressure to 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.
Products advantage
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 diameter of the pipe, it can immediately apply radial pressure to the hole wall and prevent the sliding of the surrounding rock within the full length range. In addition, the bearing capacity of the anchor rod tray support plate makes the surrounding rock in a three-dimensional stress state. Under conditions such as blasting vibration and surrounding rock anchoring, 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 has better characteristics than the expansion shell anchor rod.
