Technical requirements for slotted anchor rods

1. The surface of the joint pipe anchor rod should be flat and free from serious strain or rust. The weld seam should be free of cracks, pores, and slag inclusions, and it is not allowed to burn through the pipe wall. The tray should be able to move freely on the pole body. It is advisable to misalign the retaining ring interface with the pipe seam opening by 170o to 190o.
2. The pull-off force of the retaining ring weld seam is ≥ 80kN, the ultimate tensile strength of the rod body is ≥ 110kN, the initial anchoring force is ≥ 25kN/m, and the bearing capacity of the tray is ≥ 65kN
Technical performance
1. Initial anchoring force: 3-7 tons;
2. Pipe ring pull-off load: 8-10 tons;
3. Anchor rod pipe tensile breaking capacity: 12-13 tons;
4. The corrosion resistance is 20-30% higher than A3 steel, which is beneficial for long-term use.
