地下连续墙是建造地下构筑物的一项新技术,它是在地面上采用一种挖槽机械,沿着深开挖工程的周边轴线,在泥浆护壁条件下,开挖一条狭长的深槽,清槽后在槽内吊放钢筋笼,然后用导管法浇筑水下混凝土,筑成一个单元槽段,如此逐段进行,在地下筑成一道连续的钢筋混凝土墙壁 The underground continuous wall is a new technology for the construction of underground structures. It uses a kind of trenching machine on the ground to excavate a long narrow trench under the conditions of mud wall protection along the peripheral axis of the deep excavation project. After the trough, the reinforcement cage is suspended in the trough, and then the underwater concrete is poured by the conduit method to form a unit trough section. This is carried out step by step, and a continuous reinforced concrete wall is built underground.
