At the same time, after the soil inside the sampling tube is sampled, the soil needs to be removed, and it is impossible to form an independent space for storing different samples. Therefore, this solution proposes a multi-sample sampling device for geological engineering. Utility Model Content

[0017] 2. More importantly, the present application ensures that the obtained columnar soil maintains its original, continuous, and structurally complete geological stratification at different depths, which avoids the problem of serious damage to the structure of the soil sample and the loss of stratification information caused by the large friction and scratching of the soil core when it is pulled out of the sampling tube.

[0018] 3. After being taken out, the sleeve A and the sleeve B can be separated from each other, so that a complete columnar sampling specimen can be exposed without damage and completely, which greatly facilitates the subsequent labeling of the structure of the soil and the research on the properties of the soil, thereby truly realizing the effective preservation and high-precision analysis of different levels of soil samples.
