SJL-120 Crawler Drilling Rig
SJL-120 crawler drilling rig is suitable for the MJS (Metro Jet System) construction application. It employs a unique multi-hole drill pipe and drill bit to achieve forced slurry discharge and underground pressure monitoring inside the borehole. By forcibly adjusting the slurry discharge volume to control underground pressure, it significantly reduces impacts on the surrounding ground environment and guarantees the diameter of the constructed piles underground.
