Plain Cable Bolt
- -The rod is made of steel strands, and its flexible shear bearing capacity is the same as that of cables.
- -High strength: Capable of withstanding significant loads, it provides reliable support for tunnels, mining areas, etc
- -Good stability: Effectively control the deformation of surrounding rock and enhance the stability of surrounding rock.
- -Adapt to complex geological conditions: It can function in various different geological environments, including soft rock strata, fractured rock strata, etc
- -Strong durability: It has excellent corrosion resistance and can maintain stable performance for a long time in underground environments.
Plain Cable Bolt Functions
Plain Cable Bolt is important support components widely used in mine engineering, mainly composed of steel strands, riggings, plates and other parts. By inserting cables into the interior of the surrounding rock and applying prestress, the unstable rock strata are linked with the deep stable rock strata to form an integrated whole, jointly bearing the pressure of the surrounding rock.
Plain Cable Bolt Features & Advantages
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.
