Description

Technical Field

[0001] This utility model relates to the field of soil pollution monitoring and remediation technology, specifically a soft soil sampling device for soil pollution detection. Background Technology

[0002] Soil pollution monitoring refers to determining environmental quality (or pollution level) and its changing trends by measuring soil quality. Soil pollution monitoring typically requires multiple samplings of the soil in the testing area, followed by soil sample analysis. Existing soil sampling devices usually require inserting a casing into the soil by rotating or pressing it down. The soil is then squeezed into the casing by pressing down, and the soil is extracted using the friction between the compressed soil and the inner wall of the casing. However, this method requires considerable compression of the soil to prevent it from slipping out of the casing when sampling soft soil. This compression deforms the sample, which is detrimental to preserving its morphology. Since soil morphology is a crucial indicator in soil pollution monitoring, existing soil sampling devices are insufficient for sampling soft soil. Utility Model Content
