A Method of Water and Soil Integrated Sampling

Abstract

The invention discloses an integrated water and soil sampling method. The method is characterized by comprising steps as follows: an outer sleeve is pressed in the position above the sampling depth of soil mass, and soil mass in the outer sleeve is cleared up; an inner tube sampler is put in the outer sleeve and reaches the sampling depth for soil sampling, then the outer sleeve is pressed to the sampling depth, the inner tube sampler is lifted upwards to the ground, and a soil sample is taken out; an underground water monitoring well casing is arranged in the outer sleeve, then the outer sleeve is lifted upwards, and water is sampled from the underground water monitoring well casing after underground water is recovered. The method has the advantages as follows: effective pollution isolation can be realized during stratified sampling of soil, and an underground water monitoring well is built rapidly; compared with a traditional sampling and well building method, the method has the advantages that the sampling is more targeted, the implementation is convenient, the period is short and the like, and the method has good technical advantages and application prospect.

Description

technical field [0001] The invention belongs to the technical field of environmental geotechnical engineering, and in particular relates to a water and soil integrated sampling method. Background technique [0002] With the rapid development of society and economy, the level of urbanization has been continuously improved, but the environmental pollution has become increasingly serious, seriously destroying the ecosystem and affecting the quality of life and health of human beings. In the process of redevelopment of contaminated sites, comprehensive and accurate site surveys are very important to prevent and control ecological accidents at construction sites and construction safety accidents caused by soil and groundwater pollution. [0003] At present, the investigation of contaminated sites mainly relies on equipment such as the 30-type drilling rig, the 100-meter drilling rig, and the Geoprobe drilling rig. During the drilling process, the above-mentioned equipment may bri...

Problems solved by technology

[0003] At present, the investigation of contaminated sites mainly relies on equipment such as the 30-type drilling rig, the 100-meter drilling rig, and the Geoprobe drilling rig. During the drilling process, the above-mentioned equipment may bring surface or shallow pollution into the deep layer, and the pollution isolation has not been achieved. During the process, large-scale drilling and sampling are required. If effective measures are not taken to isolate sections, the pollution in the site will spread and secondary pollution will occur in some areas.

[0004] At the present stage, pollution isolation is rarely achieved in the process of site investigation at home and abroad. Effective isolation is conducive to the accuracy of the investigation and the protection of the environment, so there is an urgent need for a polluted site drilling that prevents secondary pollution. method, the invention of this method is conducive to ensuring the accuracy of the site survey work and effectively preventing cross-contamination during the site survey process, effectively controlling the spread of pollution caused during the survey process, and quickly and effectively realizing the integration of water and soil sampling
