Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: in the process of collecting soil layer samples by the drill pipe, there is a large friction force between the soil and the inner wall of the drill pipe, so that the soil is squeezed up and down when entering the inside of the drill pipe. Deep soil layers may be mixed during extrusion, affecting the accuracy of test results

Embodiment Construction

[0044] The following is attached Figure 1-8 The application is described in further detail.

[0045] see figure 1 , is a sampling device for geotechnical engineering drilling survey disclosed in the embodiment of the present application, comprising a body 1 of the sampling device arranged in a sampling hole, and the sampling hole is drilled by a drilling rig.

[0046] see figure 1 , the body 1 includes a base 2 , a top base 3 and a support column 4 , and the support column 4 is symmetrically fixed between the base 2 and the top base 3 to realize the connection between the top base 3 and the base 2 . Both sides of the bottom of the top base 3 are respectively fixedly connected with fixing plates. When in use, the body 1 is put into the sampling hole so that the bottom of the base 2 abuts against the bottom of the sampling hole, and the bottom of the fixing plate abuts against the ground around the top of the sampling hole.

[0047] see figure 2 A mounting column 5 is arra...
