摘要
水泥—膨润土作为柔性防渗墙墙体材料,在欧美国家已经得到广泛应用。近几年来我国在一些垃圾填埋场、危险废弃物处置中心等工程项目也引进了该项技术,但是水泥—膨润土和GCL防水毯(钠基膨润土防水毯)复合体作为垂直防渗墙的研究及应用国内比较少见,通过定远县炉桥镇垃圾填埋场GCL复合垂直柔性防渗墙工程的施工,探讨该技术的施工工艺。
As a flexible diaphragm wall material, cement bentonite had been widely used in Europe and America.In recent years, this technology had been introduced into some landfills, hazardous waste disposal centers and other projects in China. However, the research and application of cement bentonite and GCL waterproof blanket(sodium bentonite waterproof blanket) composite as vertical flexible cut-off wall were relatively rare in China. Through the construction of GCL composite vertical flexible cutoff wall in the landfill site of Fuqiao Town, Dingyuan County, the construction technology was discussed.
