Bearing capacity detection device for foundation

The invention relates to the technical field of foundation bearing capacity detection, and discloses a foundation bearing capacity detection device which comprises a driving hammer rod and a bottom plate, the driving hammer rod is provided with a first screw fixedly installed at the top end of the driving hammer rod, a detection mechanism comprises a plurality of probe rods, the bottom of each probe rod is provided with a first threaded groove, and the top of each probe rod is fixedly connected with a second screw. According to the fixing mechanism, a side plate is fixedly installed on the left side of the top of a bottom plate, a concave hole is formed in the left side of the side plate, and two rod grooves are sequentially formed in the top of the right side of the side plate. The probe rod is vertically limited by adjusting the hydraulic rod and pushing the two arc arms, so that the trouble of manual calibration and supervision is saved, the accuracy of vertically puncturing the ground during operation is
