Abstract

The invention belongs to the technical field of geotechnical engineering equipment, and relates to geotechnical engineering investigation sampling equipment which comprises a sampling barrel, at least one sampling opening, an arc-shaped baffle and a transmission disc, the sampling barrel is horizontally arranged in the sampling barrel and located above the arc-shaped baffle, and the transmission disc is connected with the upper end of the arc-shaped baffle; the first transmission rod is vertically arranged in the sampling barrel, and the first transmission rod penetrates through the transmission disc and is connected with the transmission disc; the displacement assembly is arranged in the sampling barrel and is used for driving the first transmission rod to move upwards during sampling; the reset assembly is arranged in the sampling barrel and used for driving the first transmission rod to reset after sampling is completed. According to the soil sampling device, the sampling opening can be opened through upward movement of the arc-shaped baffle during sampling, and the sampling opening is closed through downward movement of the arc-shaped baffle after sampling is completed, so that the situation that soil samples at different depths are mixed is avoided, and the accuracy of a final detection result is ensured.
