Anchor drilling rigs generally consist of crawler chassis, slewing frame, retractable boom, auxiliary platform, hydraulic control system, engine system, drill pipe propulsion mechanism and other accessories. The drilling rig's rotational power, propulsion power and auxiliary actions are all powered by hydraulic pressure, and the hydraulic station is driven by a motor or internal combustion engine. Anchor drilling rigs are mainly used for landslide and dangerous rock mass anchoring projects in the prevention and control of various geological disasters in hydropower stations, railways, and highway slopes. They are especially suitable for high slope rock mass anchoring projects, and are also suitable for the construction of urban deep foundation pit support and reinforcement projects. Kong et al.
