Polluted site blocking system based on aquitard at bottom
The invention provides a polluted site blocking system based on an aquitard at the bottom. The system is characterized by comprising an anti-seepage curtain arranged around a polluted site, wherein a flood intercepting ditch is formed in the inner side of the anti-seepage curtain, first-class monitoring wells are arranged on the two sides of the anti-seepage curtain, the first-class monitoring well is also arranged in an unpolluted area outside the anti-seepage curtain to serve as a background reference well, and the blocking effect of the blocking system is determined by comparing the water quality in the first-class monitoring well with the water quality in the background reference well. According to the system, whether gaps exist between pile bodies can be detected, whether the defect parts of the pile bodies are permeable can be determined, under the conditions that a relative water-resisting layer of the polluted site is the aquitard and cross-flow pollution possibly exists, the short-term and long-term effects of pollution prevention and control are well judged, and the system is economical, efficient, low in cost, simple, direct and easy and convenient to operate.
本发明提出了一种基于底部为弱透水层的污染场地阻隔系统，其特征在于，包括围绕污染场地设置的防渗帷幕，所述防渗帷幕内侧设置有截洪沟，于所述防渗帷幕两侧设置有第一类监测井，于防渗帷幕外的未污染区域亦设置有第一类监测井作背景参照井，比对第一类监测井和背景参照井中水质以确定阻隔系统的阻隔效果。本发明可以检测到桩体间是否存在间隙，可以确定桩身的缺陷部位是否透水，在污染场地相对隔水层为弱透水层且可能存在越流污染的情况下，很好地判断污染防治的短期和长期效果，经济高效，成本低，简单直接，操作简单方便。
