| Abstract: | In the top-down covered excavation for building a subway station, the intermediate column fabrication is the extremely essential working procedure. Once deviation of the column Position occurs, it is very difficult to adopt remedial measures. This article introduces the complete construction procedure adopted in Nanjing Xinjiekou Subway Station. A steel thimble was adopted to separate the water and form the underground operation space. A pre-computed course locator was employed to complete the steel-pipe column installation and the concrete fabrication through the cup mouth. |
