Split Bolts Of The Best Quality

Product Description

Hollow anchor rod, also called rock stabilizer, is an advanced material essential for underground support. Pipe slit anchor is a highly specialized support item, which is an advanced material used for underground culvert roof and other engineering support.

Specifications and parameters

Main Specifications: MF43 MF40 MF33

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

Material: Q235, 16Mn（Q345  Q355）, 20 Mnsi.

Technical features
1. the uncooked cloth adopts high-strength alloy strip steel;.
2. Simplest installation.
3. No anchoring agent required.
4. High friction between anchor and rock body;.
5. High shear and tensile strength; 6. Equipped with high-strength pallet, the pallet is subjected to uniform force.
6. The top of the roadway is larger than the size of the anchor rods.

Main technical performance:

Initial anchoring force: 3~7 tons; Pipe ring pull-off load: 8~10 tons; Anchor pipe pull-off resistance: 12~13 tons; Corrosion resistance is 20~30% higher than that of A3 steel, which is conducive to long-term use.

Usage

1. Determine the anchor hole position according to the design requirements, and drill the hole with drilling rig.

2. Blow out the rock powder in the hole with pressurized air.

3. The rod body mounted on the anchor disk, with an impact drill anchor into the hole pipe slit anchor drilling hole diameter recommended calculation method: rock layer: drilling diameter = (0.9-0.95) x anchor diameter anchor drilling depth: anchor length +100mm drilling deflection rate <1% coal layer: drilling diameter = (0.9-1.00) x anchor diameter anchor drilling depth: anchor length +200mm drilling deflection rate <1.5%. Drill deflection <1.5%.
