Geotechnical engineering drilling rig

The utility model relates to the field of geotechnical engineering, and discloses a geotechnical engineering drilling rig which comprises a drilling rig body, a supporting base is installed at the bottom end of the drilling rig body, four cross-country rolling wheels are installed at the bottom end of the supporting base, two supporting vertical rods are installed on the surface of the top end of the supporting base, and a supporting transverse plate is installed at the top ends of the supporting vertical rods. The geotechnical engineering drilling device is small in overall size, the cross-country rolling wheel moving device body can be remotely controlled to reach a designated drilling site through a terminal, a lifting hydraulic lifting shaft drives a rotating shaft to ascend and descend, and therefore a rotating motor drives the rotating shaft to drive a drilling bit to excavate and drill a soil layer, soil layer drilling can be conveniently and rapidly conducted, and the drilling efficiency is improved.
