为快速采集无井软土层地区地下水样品,在分析现有的浅井成井工艺和浅层地下水取样技术的基础上,提出了无井软土层地区快速成井装置和人工直接推进装置,并推荐了配套采集地下水样品的方法。快速成井装置实现了软土地区一次性成井,简化了成井步骤,节省人力和时间;人工直接推进装置首次实现了无动力装置状况下,人工快速采集浅层地下水。为无井区地下水样品采集、水质监测等工作提供了新的技术方法。
In order to quickly collect groundwater samples from wells without soft soil layer, based on the analysis of the existing shallow well completion technology and shallow groundwater sampling technology, a rapid well completion device and a manual direct propulsion device in the area without soft soil layer are proposed. Supporting the collection of groundwater samples. Rapid well-forming device to achieve a one-time soft soil into the well, simplifying the well-forming steps to save manpower and time; artificial direct propulsion device for the first time without power device conditions, the artificial rapid acquisition of shallow groundwater. It provides a new technical method for groundwater sample collection and water quality monitoring in no well area.
