Hot Galvanized Ground Drill Anchor Plate For Slope Stabilization
Anchor bolt
Anchor bolt means a rod that transfers the structures or
geotechnical load to a stable rock formations,
it consists of 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.
Selt-Drilling Anchor Bolt Description
It may bodies drilling, grouting and anchoring as a whole.
It has a wide specifications. Diameter:25-130mm.
Qucik and easy construction, high efficiency.
Used invious surrounding rocks.

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.
