Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of geological exploration equipment and relates to a soil sampling device for environmental geological exploration. Background Art
[0002] There are two commonly used methods for soil sampling: mixed soil sample collection method and profile soil sample collection method. The two methods are used for different testing needs. The mixed soil sample collection method is mainly used to analyze the composition of soil in a specific area, reducing the impact of specificity through mixing. The profile soil sample collection method is to collect samples at a specific depth in the soil profile.
[0003] The traditional profile soil sample collection method requires digging a pit of a certain depth and then collecting samples from the profile. The profile must have a high verticality. However, in some areas with dry soil, the vertical profile soil will naturally slide or collapse. If sampling is carried out from top to bottom, the upper layer will slide to the soil below, which will affect the test results. If sampling is carried out from bottom to top, then after the sampling below is completed, the upper layer will be more likely to collapse or slide. Summary of the Invention
