Plain Cable Bolt
Plain Cable Bolt Functions
Cable bolt could provide higher tensile strength,anti-shearing capacity and incomparable bending capacity,
and could prevent the lateral movement of strata.
Plain Cable Bolt Features&Advantages
Plain cable bolt
Available in single strand or twin strand
Fish hooks fitted to top of cables for retention prior to grouting
Resin could be applied for immediate point anchorage and grout for permanent support

How to work
Assess the ground conditions thoroughly.
Bore a hole based on the bolt's diameter and length, ensuring it's 200mm to 500mm shorter than the bolt itself.
Fix a breather tube along the entire length of the bolt, allowing it to extend approximately two meters from the hole.
Affix roughly one meter of grout tube to the cable bolt's end, leaving enough excess to connect to the pump.
Place the cable bolt into the hole and seal it to prevent grout loss during pumping.
Link the grout tube to the pump and submerge the breather tube in a water container. Start pumping and observe air bubbles escaping in the water.
Once the hole is filled and bubbles cease, the grouting is complete.
Tension the cable bolt after the grout has set.
