混凝土防渗墙主要应用于堤身及基础的垂直防渗,也可用作土石坝防渗加固和坝体防渗心墙。文章通过工程实例,详细介绍了一种高含水率淤泥质土层中混凝土防渗墙的施工工艺及方法,槽段划分的合理性,并对槽段施工提出了具体方法及施工的注意事项。该施工工艺提高了造墙效率,成墙质量有所提高,能够解决防渗墙塌孔的难题。
Concrete cutoff walls are mainly used in the vertical seepage of the dike and the foundation, but also can be used as seepage prevention and reinforcement of earth dam and dam impervious core wall. The article introduces the construction technology and method of concrete cutoff wall in a silty soil layer with high water content and the rationality of the division of the slot section through engineering examples. It also puts forward the specific methods and precautions for the construction of the slot section. The construction process improves wall efficiency, wall quality has improved, to solve the problem of impervious wall collapse holes.
