[0001] This utility model relates to the technical field of geological exploration and sampling devices, specifically a geological exploration and sampling device for transportation road and bridge engineering. Background Technology

[0002] In the construction of transportation, road, and bridge engineering, geological investigation is a crucial step. Accurate understanding of geological conditions is decisive for designing reasonable bridge foundations and road structures. Existing geological investigation and sampling devices for transportation, road, and bridge engineering typically involve inserting a sampling tube into the ground using an electric drill to extract geological samples. Usually, only one power unit is installed, resulting in low sampling efficiency. Furthermore, after sampling through the tube, it is inconvenient to automatically remove the geological samples; usually, other tools are needed to scoop them out, hindering work efficiency.

The sampling tube 260 cuts the ground in a ring, so that the sampling tube 260 is inserted below the ground to sample the geology. Then, the first cylinder 230 is driven to retract the rod to pull the sampling tube 260 out of the ground. By opening the second cylinder 320, the second cylinder 320 pushes the unloading push rod 330 to push the geological sample inside the sampling tube 260 to be ejected.
