Description

Technical Field

[0001] The present application relates to a foundation soil sampling device. Background Art

[0002] In order to measure the soil mechanics parameters, it is necessary to sample and analyze the soil. There are many kinds of soil sampling devices now, which are mainly determined for different soil conditions. For hard soil sampling, the rotary sampling method is generally used. The soil sampler is drilled into the soil, and then the soil is introduced into the soil sampler, and then the sampling component is pulled out to obtain the soil to be tested; for thin mud, a straight-line sampler is generally used for sampling.

[0003] The problem with current soil samplers is that in the height direction, they generally use mixed sampling devices, which make it impossible to make comparisons in the height direction. A multi-level sampling method is required to achieve the goal. The sampling process is cumbersome, and during the sampling process, the soil between different layers may also be mixed.
