Abstract

The invention belongs to the technical field of underground water sampling and particularly relates to an underground water depth-setting stratified sampling device and an underground water depth-setting stratified sampling method applicable to regions without wells. The underground water depth-setting stratified sampling device at least comprises a sampling mechanism, a connecting mechanism and an underground sample injection mechanism, wherein the sampling mechanism comprises a first sampling mechanism body, a second sampling mechanism body, a sampling bottle, a gas-phase check valve, a nested flow splitting mechanism, a ball valve and a wellhead fixing support seat, the underground sample injection mechanism comprises a first underground sample injection mechanism body and a second underground sample injection mechanism body, and the connecting mechanism comprises a first connecting rod and a second connecting rod. Compared with similar technical products, the underground water depth-setting stratified sampling device applicable to the regions without the wells has the advantages that the device is novel in structural design and improved in working performance, functions, precision, stability and durability substantially, integrates a high-precision stratified sampling function and an underground water level line fluctuation monitoring function and can be rapidly mounted in the regions without the wells.

Description

technical field [0001] The invention belongs to the technical field of groundwater sampling, and in particular relates to a groundwater depth-fixed and layered sampling device and method suitable for areas without wells. Background technique [0002] Groundwater is an important factor related to the evolution of the earth and the survival of life on the surface. Groundwater sampling can provide a large amount of physical, chemical and microbial information about the formation by cooperating with relevant testing techniques, and it is one of the monitoring methods that have important guiding significance for engineering development and environmental safety assessment. In particular, human activities, such as infiltration of landfill leachate, underground discharge or leakage of pollution sources in industrial parks, pollution from agricultural activities, etc., cause pollution sources to infiltrate into shallow groundwater, and spread horizontally and vertically to larger aff...
