为了控制垃圾渗滤液的侧向渗透,在城市垃圾卫生填埋场四周需设置垂直隔离墙.隔离墙采用现场开挖深槽,然后在槽内灌注水泥-膨润土-砂混合浆液的方法构筑.通过室内配比试验的方法,测定不同配比试件的无侧限抗压强度、渗透系数等参数,为隔离墙的施工提供合理的配比.
為瞭控製垃圾滲濾液的側嚮滲透,在城市垃圾衛生填埋場四週需設置垂直隔離牆.隔離牆採用現場開挖深槽,然後在槽內灌註水泥-膨潤土-砂混閤漿液的方法構築.通過室內配比試驗的方法,測定不同配比試件的無側限抗壓彊度、滲透繫數等參數,為隔離牆的施工提供閤理的配比.

For control of the waste leachate lateral permeability, a cutoff wall is under construction around the site of Shanghai Laogang MSW Landfill phase IV. The containment wall is installed by a method that the slurry of cement, bentonite, soil and water is bumped and poured into a slot, which has been excavated in place. The reasonable and feasible ratio of different component of the slurry was decided through laboratory tests, including sample preparation, unconfined Strength test and permeability test.
