The anchor drilling rig is mainly used in hydro power stations, railways and highways, in order to prevent and control various geological disasters, anchoring operations are carried out on landslides and dangerous rock masses.It is mainly used in landslide and dangerous rock anchoring projects in tunnels, railways, highway slopes and other kinds of geology, especially for high slope rock anchoring projects. Drilling operations consume less manpower and material resources, have high construction efficiency and high safety factor. It is also suitable for the construction of deep foundation pit support, reinforcement hole for anti-float anchor and foundation grouting, blast-hole in blasting project, high pressure sprinkling stake and tunnel pipe support hole, etc..
The drilling technology with casing of anchor drilling rig is designed to solve the problem that complex rock layers cannot be holed. The drill bit impacts rock continuously, and the broken rock is blown to the ground by the air pressure discharged from the gap between the casing and the drill pipe. The drill pipe and bit can be lifted after punching the hole, and the casing is placed in the middle of the rock layer, so that the rock layer doesn't collapse.
