Geotechnical Engineering 450 Depth Crawler Hydraulic Reverse Circulation Drilling Rig

Introduction of 450 crawler type water well drilling rig

Water gas dual-purpose drilling rig is a mechanical top drive drilling rig integrating water drill and air drill. It effectively solves the problems of difficult drilling with air DTH hammer in soil layer and low efficiency of water drilling mud in hard rock layer, gravel and pebble layer.
The drilling rig is suitable for various complex strata, drilling and geological exploration, drilling core, high efficiency and energy saving. It is the inevitable trend of equipment development in water well drilling and geological engineering exploration industry in the future.
