| Abstract: | ＂Two walls combined into one＂ means that single earth retaining structure is turned to be external wall of perma- nent basement structure. The paper introduced the construction case in complex surrounding environment and geological conditions with this technology. In super-wide and super-deep diaphragm wall construction, trenching stability, large diam- eter reinforcement cage hoisting and putting or drawing for fore shaft pipe were successfully performed, the experience was provided for super-deep diaphragm wall construction in downtown area. |
