Full rotation underground drilling rig

The construction of underground obstacle removal is to use the clamping system of the full-slewing full-slewing drill to clamp various diameter special steel casing with special cutter head, and then provide hydraulic power through the specially equipped hydraulic power station to drive the hydraulic motor and lift and drop cylinder on the full-slewing drill to rotate the steel casing into the formation and underground obstacles. Then supplemented by special crawler crane with free drop hook, impact grab, cross punch, wedge hammer and other equipment and facilities, the soil and obstacles in the casing are removed, so as to remove the underground obstacles.
