Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a wetland soil collection device for soil treatment. Background Technique

[0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. When there are too many harmful substances in the soil, exceeding the self-purification ability of the soil, it will cause changes in the composition, structure and function of the soil. The activities of microorganisms are inhibited, and harmful substances or their decomposition products gradually accumulate in the soil and are indirectly absorbed by the human body through "soil → plant → human body" or "soil → water → human body", reaching the level of harming human health, which is soil pollution. Soil remediation is a technical measure to restore the normal function of polluted soil. When carrying out soil pollution treatment, it is usually necessary to collect soil.

[0003] In the process of soil pollution treatment, a soil collection device is needed to collect soil. Usually, an insertion sampling of soil is carried out by a tubular device. However, in relatively wet or wetland soil, when sampling, it is impossible to stably collect relatively slippery or fluid soil well. After collection, the fluid soil is easy to flow away, and the collection accuracy and convenience are relatively insufficient. Moreover, it is impossible to conveniently complete the simultaneous collection of shallow soil and deep soil at one time, and the stratified isolation collection ability is relatively not good, and the collection adaptability is relatively insufficient, reducing the practicability of the collection device. For this reason, we propose a wetland soil collection device for soil treatment to solve the above problems. Content of the Utility Model
