直接推进在场地污染调查中的应用研究

Study on Direct Pushing Technology in Contamination Investigation

摘要:

直接推进取样技术按照监测要求，可以在同一孔内迅速准确地采取地下水水样、土层土样和土层气体样品。直接推进取样完成后，还可以在孔内安装井管和过滤管，成为永久性的监测井。该项技术可以为查明潜在的污染工厂、废水土地处理场和垃圾填埋场的地下水是否受到污染以及污染的扩展情况提供分析样品。该项技术施工成本低，可获取高质量的监测资料，为控制和治理地下水污染提供科学依据。我们结合地质调查项目对直接推进取样技术进行了试验研究，取得了一些认识。

Abstract:

In accordance with the monitoring requirements, direct pushing technology can get groundwater, soil and gas samples rapidly and accurately. After sampling, it can be installed with well pipe and screen, using as a permanent monitoring well. The technology can provide analysis of samples to identify the potential contaminated sites. With the advantages of low cost and high efficiency, this technology can provide a scientific basis for management of groundwater and soil pollution. Some technical understanding was discussed in the paper.
