摘要
一般地下连续墙具有挡土、防渗的作用,但是其结构存在着施工冷缝等不利因素.因此,亟需探索新的地下连续墙结构,补足地下连续墙结构上的不足.基于相关实践,对防渗膜地下连续墙、钢箱地下连续墙以及钢筋笼附膜地下连续墙3种工艺进行了介绍,并与一般地下连续墙进行了包括防渗能力、结构整体性、综合受力能力以及施工难易程度、施工成本等方面的对比.相关工艺可以为类似工程项目施工提供参考.
Abstract
Generally,the underground diaphragm wall has the function of retaining and seepage control,but its structures have the disadvantages such as construction of cold joints.Therefore,there is an urgent need to explore the new diaphragm wall structures to complement the structural deficiencies of diaphragm walls.Based on the relevant practice,three types of underground diaphragm walls,such as impermeable membrane diaphragm wall,steel box diaphragm wall and steel cage attached membrane diaphragm walls are introduced,and compared with the general diaphragm walls in terms of impermeability,structural integrity,comprehensive force capacity,construction difficulty and construction cost.The relevant process can provide a reference for the construction of similar projects.
