Abstract

The invention relates to the testing or analysis of a material by means of the determination of chemical or physical properties of the material, in particular to sampling. According to the underground water sampling and monitoring device and method, at least part of the device is located in a drill hole, a first space is defined by the drill hole, and the device comprises: a layering device, wherein the layering device comprises at least one volume-variable packer, and the packer is used for dividing the first space into at least one closed sample space distributed in the axial direction of the drill hole; a monitoring device which comprises at least one detection piece used for measuring physical parameters of underground water, wherein each detection piece is located in one sample space, and the detection pieces are connected with the layering device; and a sampling device which comprises at least one collection container for collecting underground water, wherein each collection container is located in one sample space, and the collection containers are connected with the layering device. The underground water with different depths can be sampled and monitored at the same monitoring point at the same time, that is, sampling is carried out while the physical properties of the underground water with different depths at the same monitoring point are continuously monitored.

Description

technical field [0001] The present invention relates to testing or analyzing materials by means of determining their chemical or physical properties, and more particularly to sampling. Background technique [0002] The groundwater level, conductivity, pH, and pollutant composition and content at different depths are important parameters for understanding groundwater flow velocity, flow direction, and aquifer (zone) hydraulics, and are also necessary parameters for investigating the morphology and distribution characteristics of pollution plumes and evaluating the effect of pollution remediation. Pollution plume refers to the spatial range formed by the movement of pollutants with groundwater. In related technologies, holes are usually drilled in the aquifer (belt), and pressure sensors are installed in the holes to monitor the groundwater level for a long time through the pressure sensors, or groundwater samples are regularly collected and analyzed, and the water chemical co...
