Details of Pipe Seam Anchor

Pipe seam anchor is a full-length anchoring, active reinforcement of the surrounding rock of the new anchor, its three-dimensional part is a longitudinal slit of high-strength steel pipe, when installed in a slightly smaller than the diameter of the pipe drilling, can immediately in the full-length range of the radial pressure on the hole wall and prevent the surrounding rock sliding friction, plus the anchor tray pallet bearing force, so that the surrounding rock is in a three-way state of force, and to achieve the rock layer great. In the case of blasting vibration surrounding rock anchor shift, etc., there is a significant increase in the late anchoring force, when the surrounding rock is significantly displaced, the anchor does not lose its support resistance, it has better characteristics than the rising shell type anchor.

Pipe seam anchor technical requirements

Surface of pipe seam anchor rods: the surface should be flat, without serious strain or rust. The weld should be free of cracks, porosity or slag entrapment, and should not burn through the pipe wall. The pallet should be able to move freely on the rod. The mutual misalignment between the interface of the retaining ring and the opening of the pipe seam between 1700-1900 is the best.

Requirements of technical parameters: pull-off force of retaining ring weld ≥80kN, ultimate tensile force of rod body ≥110kN, initial anchor force ≥25kN/m, bearing capacity of pallet ≥65kN.

Installation and use

1. Use wind drill to drill anchor rod holes on the top plate.

2. Put the tray into the anchor rod body.

3. Use the wind hammer to drive the anchor rod body into the anchor hole, so that the pallet and the roof gang belt are compacted.
