What are the main technical specifications and requirements for pipe socket anchor rods?

1. Key Technical Performance: (1) Initial Anchor Pull-Out Force: 3~7 tons; (2) Tubular Ring Tensile Load: 8~10 tons; (3) Anchor Rod Tube Tensile Break Strength: 12~13 tons; (4) Corrosion Resistance 20~30% higher than A3 steel, benefiting long-term use.

2. Technical Requirements 1) The surface of the pipe anchor bolt should be smooth, free of severe scratches and rust. Welds should be free of cracks, blow holes, and slag, and it is not allowed to burn through the pipe wall. The tray should be able to move freely on the rod body. The interface of the挡ring should be misaligned with the pipe seam opening by 170o to 190o. 2) The tensile force of the挡ring weld should be ≥80kN, the ultimate tensile strength of the rod body should be ≥110kN, the initial anchoring force should be ≥25kN/m, and the bearing capacity of the tray should be ≥65kN.

3. Product Usage: First, use a rock drill to bore anchor rod holes in the roof, then fit the tray onto the rod body of the anchor rod, and finally, use a pneumatic hammer to drive the rod into the anchor rod hole, ensuring the tray is securely fastened against the roof. When using the anchor rod, in addition to referring to the table above, the user should select the drilling diameter based on the specific rock conditions and in accordance with the provisions of the GBJ86 standard.
