摘要
在污染场地调查中,快速、准确地确定污染物的分布特征是调查工作的重点。作为新兴的污染场地调查技术,直接推进钻探技术可以用来进行包气带和含水层土壤样品采集、地层渗透系数探测,以及直接测定地层中污染物组成,具有快速、准确、不引起交叉污染的优点。该文对直接推进钻探当前研究进展进行介绍,并对技术改进方向进行叙述。
Accurate and rapid determination of the distribution of contaminants is the main task for the investigation work of a contaminated site .As a new surveying tool for contaminated sites ,direct push technology can be used for soil sample collection in the vadoze zone and aquifer ,detection of aquifer parameters ,and determination of pollutants .It has the advantages of fast ,ac-curate ,and free of cross-contamination .In this paper ,the development and research progress of direct push technology was in-troduced ,and the technology innovation was discussed .
