Road and bridge compactness test detection device

The invention discloses a road and bridge compactness test detection device, and belongs to the field of compactness detection.The road and bridge compactness test detection device comprises a frame, the frame comprises a pull rod slidably connected to the interior of the frame, a motor is fixedly connected to the bottom of the pull rod, and a soil sampler is fixedly connected to the bottom of the motor; the soil sampler is used for sampling soil needing to be inspected in a unit; and a connecting rod is slidably connected to the interior of the soil sampler, and a first disc is fixedly connected to the bottom of the connecting rod. The pull rod is used for controlling the motor so as to control the downward moving distance of the soil sampler, the soil sampler enters the soil with the compaction degree needing to be detected, the connecting rod is moved to drive the first disc to move in the soil sampler, the soil in the soil sampler is taken out, and the measured soil can be conveniently observed; whether b
