description The utility model discloses a portable on-site sampling device for geotechnical engineering survey, which comprises a support and a support rod, and is characterized in that a support tube is fixedly arranged in the middle of the support, a first screw rod is connected with a sleeve in a threaded meshing manner, the other end of the sleeve is connected with a second screw rod in a threaded meshing manner, and the second screw rod is connected with a first screw rod. A graduated scale is fixedly arranged on the outer wall of the drill pipe, a supporting pipe is connected to the inner side of the upper end of the drill pipe through a shaft sleeve, three annular baffles of the same specification are welded to the annular support, the height of the support can be adjusted through a sleeve, the road holding force is enhanced through spiral teeth on a fixed drill bit, and therefore the overall stability performance is improved. In the stratified sampling process, the insertion depth is judged according to the gradu
