土壤污染状况调查取样设备与工艺探索

Review of Developments in Sampling Device and Process the Investigation in Contaminated Soils

取样设备与工艺是土壤污染状况调查过程中的关键因素之一。将土壤污染状况调查与传统岩土工程勘察进行了对比,针对污染场地调查取样工作特点,比较了常用的污染场地调查取样设备和工艺,给出了针对不同地层的推荐设备与工艺,并对推荐设备中取土器和水样取样器进行了改进,列出调查及取样过程中的注意事项,并指出了污染场地采样设备未来的发展方向,对土壤污染状况调查现场取样工作具有很好的指导意义。现有取土器和水样取样器需要经过适当改进才能更好满足污染场地调查工作的要求。

Sampling devices and process are the key factors in the environmental investigation of contaminated soils.This paper compares the aspects of the contaminated soil investigation with the traditional geotechnical sampling and testing procedures.The soil and water sampling devices that are commonly used in different contaminated sites and various soil stratigraphy are reviewed and commented.The key technical procedures in the investigation are also introduced in detail in the paper.The future development of contaminated soil sampling device and drilling process are reviewed.It is concluded that the current soil and water sampling devices should be appropriately modified to meet the requirements of the contaminated soil investigations.
