Before building a water conservancy project, it is necessary to conduct a geological survey of the construction site. During the survey, a geotechnical sampling device is needed to obtain soil samples in the construction area for subsequent water conservancy project construction work.

[0003] In the prior art, most sampling devices are cumbersome to install during use. It is necessary to manually extrude the sample from the sampling tube to observe it, which is likely to cause soil displacement. Moreover, when sampling in a small area, larger devices have higher costs and are not convenient to use. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a geotechnical sampling device for water conservancy project detection to solve the technical problems of inconvenient sample observation and high cost.

The sampling cylinder is rotatably connected with a first cylinder piece and a second cylinder piece through two groups of rotating shafts respectively. A push plate is movably connected inside the sampling cylinder. Multiple groups of evenly distributed springs are fixedly connected to the bottom of the push plate. The sampling cylinder and the springs are fixedly connected through fixing blocks. Fixed plates are fixedly connected inside both the first cylinder piece and the second cylinder piece. Drums are rotatably connected to the ends of the two fixed plates.

[0006] By adopting the above technical solution, a structure for sampling soil by forming a cavity with the first cylinder piece, the second cylinder piece and the push plate, and a structure in which the two cylinder pieces make the drum squeeze the push plate to rise through the rotating shaft, a sampling cylinder that is more convenient and faster to take out the sampled soil is achieved.

[0007] Further, the first cylinder piece, the second cylinder piece and the push plate form a cavity, and the first cylinder piece and the second cylinder piece are not connected to each other.

[0008] By adopting the above technical solution, the function of sampling soil is achieved.

[0009] Further, a drill bit is fixedly connected to the bottom end of the sampling cylinder, and a sampling hole matching the cavity is opened inside the drill bit.

[0010] By adopting the above technical solution, the functions of inserting the sampling cylinder into the ground and collecting soil are achieved.

[0011] Furthermore, a top plate is fixedly connected to the top end of the sampling cylinder, and the first cylinder piece and the second cylinder piece are attached to the bottom surface of the top plate and are not connected.

[0012] By adopting the above technical solution, the effect of simultaneously opening the two groups of cylinder pieces is achieved.

[0013] Furthermore, a handle is fixedly connected to the top end of the top plate, and the handle is in a "T" shape.

[0014] By adopting the above technical solution, the function of facilitating the user to rotate and insert the whole into the ground and pull it out is achieved.

[0015] To sum up, the present utility model mainly has the following beneficial effects: The present utility model forms a cavity through the first cylinder piece, the second cylinder piece and the pushing plate to sample the soil, and the structure in which the two groups of cylinder pieces make the roller squeeze the pushing plate to rise through the rotating shaft, achieving a sampling cylinder that is convenient for more quickly and conveniently taking out the sampled soil. Through the structure of arranging multiple groups of springs and fixing blocks at the bottom end of the pushing plate, the function of simultaneously resetting and moving the pushing plate, the first cylinder piece and the second cylinder piece is achieved.
