Curing agent-mud soil mixed cushion layer for site anti-seepage treatment
The invention relates to a curing agent-mud soil mixed cushion layer for site anti-seepage treatment. The mixed cushion layer comprises a plain soil punning layer, a bottom layer, crushed rock layers,a middle layer, a sand cushion layer and a surface layer which are laid from bottom to top one by one, and the bottom layer, the middle layer and the surface layer are all formed by laying solidifiedimpermeable soil. The solidified impermeable soil is formed by mixing clay and dredged silt, adding soil stabilizer and stirring and curing mixtures; two adjacent impermeable layers are spaced through the crushed rock layers and the sand cushion layer separately, and the better impermeable effect can be achieved. The mixed cushion layer is simple in structure, convenient in construction and advanced and scientific in method; through the mixed cushion layer, not only can outward transport of the dredged silt and earthwork be reduced, but also the problem of underground environment pollution due to permeation of leachate produced in the dredging process can be solved properly.
本发明涉及一种用于场地防渗处理的固化剂‑淤泥土混合垫层，包括从下至上逐层铺设的素土夯实层、底层、碎石层、中层、砂垫层和面层，所述底层、所述中层和所述面层均由固化防渗土铺制而成。固化防渗土由粘土和疏浚淤泥混合后掺加土壤固化剂经拌和、闷料后而成；相邻的两层固化防渗土层分别用碎石层和砂垫层相隔，可以起到更好的防渗效果，本发明结构简单、施工便捷、方法先进科学，通过本发明，不仅可以减少疏浚淤泥和土方外运，而且可以很好地解决淤泥疏浚过程中所产生的沥液渗透污染地下环境的问题。
