The drilling auxiliary time is short, the labor intensity is low, the sludge circulation is not needed to discharge slag, the cost is saved, and the method is particularly suitable for the foundation construction of urban construction. Because the rotary drilling rig is used for basic construction, places which cannot be seen by naked eyes are constructed by a vehicle-mounted computer and the experience of a manipulator, the requirement on the manipulator is higher. At present, the existing rotary drilling rig has risks in the aspect of operation and control under the following two conditions:
