    Hollow Anchor Rods for Mining

     

    Anchor bolt

     

    Anchor bolt means a rod that transfers the structures or geotechnical load to a stable rock formations,

     it consistsof rod, drill bit,coupling, plate, grouting stopper and nut. It has been widely used in tunnling,

     mining,slope stabilization, tunneldiseasestreatment and roof supporting of undergroundworks. It is for 

    loose ground(clay, sand friable etc.) Hollow anchor rod is made of seamless tube with high strength.

     

    Features of Hollow Grouting Anchor Bolt:

     

    Hollow design, implement the grouting tube function, avoid the mortar loss when the traditional grouting

     tube pulled out.Grouting full, and can achieve the pressure grouting to improve project quality.

    Center is good, mortor can wrap the bolt body together, so that it can avoid corrosion to achibe along 

    term supporting purposes.

    Easy installation, without onsite processing of threads. It can be easily installed an plate, nut.

    High Strength Self Drilling Bolts Rod Steel Anchor Bolts Easy Installation

    1. Connect the alloy drill and anchor rod one end, on the other end, connect the drill sleeve and shank adapter ,then connect the drilling rig or hand-held drill. Then start drilling, fill the cooling water while drilling.( If you want to lengthen the anchor rod, can connect the coupling, and then drilling)

    2. Take down the drill, put the stop-grouting plug into the rod, and insert it to the hole, then ready to grout. Special circumstances like surrounding rock grouting tension is over or surrounding rock is too broken, can use anchor agent to seal the hole.

    3. Connect quick grouting coupling and anchor rod end, connect other end of grouting machine.

    4. Start grouting, when grouting full and reach design value then power off . Grouting pressure according to the design parameters and grouting machine performance determine ,Cement/sand reference values is 1:0 ~ 1:1, water/cement reference value is 0.45:1 ~ 0.5:1.

    5. Install anchor plate and nuts, and tighten nuts.
