In-situ remediation system for polluted underground water and construction method thereof
The invention provides an in-situ remediation system for polluted underground water and a construction method thereof. The system is characterized in that a plurality of high-permeability walls perpendicular to the flow direction of underground water are arranged at intervals at the downstream of a pollution source; sealing walls perpendicular to the high-permeability walls are arranged on the twosides of the high-permeability walls, a system body is defined by the sealing walls and the high-permeability walls together, and the interior of the system body is divided into a plurality of samplespace layers used for being filled with active materials through the high-permeability walls. Flow guide walls are arranged on the two sides of the front end of the system body respectively, the twoflow guide walls extend forwards and outwards from the front end of the system body respectively to form a splayed flow guide structure, and each flow guide wall is formed by connecting a plurality ofsteel sheet piles. The steel sheet pile construction method is simple and convenient, high in mechanical utilization rate, short in construction period and low in cost.
本发明提供了一种污染地下水的原位修复系统及其施工方法，所述系统是在污染源下游间隔设有若干道与地下水流向相垂直的高渗透墙，在高渗透墙的两侧设有与高渗透墙相垂直的密封墙，所述密封墙与高渗透墙共同围成系统主体，高渗透墙将系统主体内部分隔为若干用于填充活性材料的样品空间层；在系统主体的前端两侧各自设有导流墙，两面导流墙自系统主体前端各自向前向外延伸形成“八”字形导流结构，所述导流墙由若干钢板桩连接构成。本发明采用的钢板桩施工方法简便，机械利用率高，工期短，成本低。
