| Abstract:“Two walls combined into one” means that single earth retaining structure is turned to be external wall of permanent 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 diameter 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. |
