Anchor cable is through the fixed at the other end, in slope anchorage in the sliding surface of stability within in rock mass slope of the prestressed strands through the sliding, directly in the slip surface sliding resistance, increase produce sliding friction resistance, make structure surface pressure in the state, in order to improve the integrity of the slope rock mass, thus fundamentally improve mechanical properties of rock mass, the effective control of the rock mass displacement, and urges the stable, achieve the landslide and along the layer and dangerous rock role. Anchor classification mainly has cagelike anchor cable, etc.

1. Drilling is in the construction of the control time limit anchor the critical process. To ensure that the drilling efficiency and ensure that the borehole quality, adopt the DTH impact type drill. Rig drilling, according to anchor cable length design for drilling pipe placed in order, and in the deep hole drilling pipe, also ?
