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.

Technical Parameters

Material:Q235,16Mn,20Mnsi

Outer diameter (mm):φ30,φ33,φ40,φ43 (士0.5)

Length (mm):1200,1500,1800,2000,2500

Execution standard

Coal Mine Anchor Tray, Iron Mine Anchor Tray, National Standard Anchor Tray, Non-standard Anchor Tray.

Use method

1、According to the design requirements to determine the anchor hole position, use drilling rig to drill the hole.

2、Blow out the rock dust in the hole with pressurized air.

The rod is mounted on the anchor disk, and the anchor is drilled into the hole with the impact drill. Recommended calculation method for drilling hole diameter of pipe slit anchor:In rock stratum:Drilling hole diameter= (0.9-0.95) Anchor diameter Anchor drilling depth:Anchor length+100mm Drilling deflection rate<1% In coal stratum:Drilling hole diameter= (0.9-1.00) Anchor diameter Rod drilling depth:Anchor length+200mm Drilling deflection rate<1.5%.

Scope of application

Simple installation, robustness, uniformity of force
