Product Details

Factory direct tunnel slope protection project special self-propelled hollow anchor combined hollow grouting anchor

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, tunneldiseases treatment 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.
