Construction method for repairing sensitive boundary by using complex polluted soil
The invention relates to a construction method for repairing a sensitive boundary by complex polluted soil. The type of a polluted area is determined; determining a sensitive boundary range of the polluted area; carrying out cast-in-place pile construction at the sensitive boundary along the sensitive boundary, and feeding mud generated by the cast-in-place pile construction in different pollutant characteristic areas into corresponding mud pits; polluted soil generated by construction of the cast-in-place piles in the different polluted areas is piled up to a storage yard to be drained independently; slurry concentrated wastewater in the slurry pond and drained water of the storage yard are conveyed to a tail water treatment system; and draining the polluted soil in the storage yard, transporting the polluted soil outwards, and co-processing the polluted soil in a cement cellar. The method has the beneficial effects that supporting construction can be conducted on the polluted area boundary, and the situation that the enclosure structure moves towards the repairing boundary, and consequently polluted soil exists in part of the area of the repairing boundary and cannot be repaired is avoided; cast-in-place pile construction is fused with chemical oxidation, solidification and stabilization repair and ex-situ cement kiln co-processing ex-situ repair technologies, polluted soil is repaired while cast-in-place pile construction is achieved, and the situation that polluted soil is not repaired thoroughly is avoided.
本发明涉及一种复杂污染土修复敏感边界施工方法，确定污染区域类型；确定污染区域的敏感边界范围；在敏感边界处沿敏感边界开展灌注桩施工，并将不同污染物特征区域灌注桩施工所产生的泥浆送入对应泥浆池；将不同污染区域灌注桩施工所产生的污染土分别堆存至堆场单独进行沥水；泥浆池内的泥浆浓缩废水以及堆场的沥水送至尾水处理系统；堆场内的污染土沥水后外运，并经水泥窖协同处置。有益效果为：可以在污染区域边界做支护施工，避免围护结构向修复边界内移,造成修复边界部分区域存在污染土壤无法修复；将灌注桩施工与化学氧化、固化稳定化修复及异位水泥窑协同处置异位修复技术融合，实现灌注桩施工同时，污染土修复，避免污染土修复不彻底。
