The Rockbolt accessories manufacturer tells you that the pipe joint anchor is a new type of anchor rod that is full-length anchored and actively strengthens the surrounding rock. Its three-dimensional part is a high-strength steel pipe with longitudinal slits. The Rockbolt accessories manufacturer tells you when it is installed in a pipe When drilling a hole with a smaller diameter, radial pressure can be applied to the hole wall over the full length and the friction to prevent the surrounding rock from sliding down, plus the supporting force of the anchor tray supporting plate, so that the surrounding rock is in three directions Stress state, and achieve rock stability. The manufacturer of Rockbolt accessories tells you that in the case of blasting vibration and surrounding rock anchoring, the later anchoring force increases significantly. When the surrounding rock is significantly displaced, the anchor rod does not lose its supporting resistance. It is better than the expansion shell anchor rod. Better features.

How it works: The Rockbolt accessories manufacturer tells you to install the pipe joint bolt in a borehole smaller than the pipe diameter. At this time, three forces will be applied to the surrounding rock, one is in the full length of the pipe joint bolt The inner radial pressure on the hole wall is friction force to prevent the surrounding rock from sliding down, and the other is the supporting force of the pipe joint anchor tray support plate. These three forces make the surrounding rock more stable.
