Abstract

The present application provides a geological casing comprising a casing body, a sealing airbag located at one end of the casing body for sealing one end of the casing body, and an annular support frame which is connected to the inner wall of the casing body for supporting the sealed airbag. The inner wall of the annular support frame is provided with a storage tank for storing the sealed airbag;the sealed airbag is located in the storage tank and is fixedly connected to the annular support frame; a venting hole vertically facing the sealed airbag is formed on the casting body away from the end surface of the sealed airbag; the venting hole is communicated with the sealed airbag through the annular support frame; in the process of taking the soil, the sealed airbag is filled with gas through the venting hole, the soil in the annular supporting frame is squeezed by the sealed airbag to stabilize the soil in the annular support frame in the annular support frame, which can effectively prevent the soil in the casing body from falling from the bottom.

Description

technical field [0001] The application relates to the technical field of geological exploration, in particular to geological casing. Background technique [0002] In the field of geological prospecting, earth-borrowers are often used when collecting soil samples. Existing soil extractor structure comprises circular base, and the center of base is fixedly connected with guide seat, and the central sliding device of guide seat takes soil rod, and the upper end of soil fetch rod is provided with screw rod, and the lower end of soil fetch rod is provided with for taking soil. The structure of the casing of the soil, the screw mandrel is spirally connected in the screw mandrel seat, and the screw mandrel seat is fixedly connected with the circular base. The disadvantages of the soil extractor with the above structure are: the casing is a simple cylindrical structure, and when the soil is removed from the ground after soil extraction, the soil sample is easy to fall off from the ...
