| Abstract: | Nanjing New Railway Passenger Station lies just above the metro station of Nanjing Metro Line #1, and the two stations were in synchronous construction. Primary load of the railway station was transmitted through conversion jacking joist to pile foundation. The max. cross section of conversion jacking joist is 3 000 mm×3 000 mm, and it contains large volume of steel that causes much difficulty for concrete pouring. Besides, the steel tubular column ( 1 200 mm) of the railway station was installed inside the jacking joist. An introduction is given to comprehensive construction technology for large cross sectional conversion jacking joist and steel tubular column. |
| Keywords: | conversion jacking joist formwork support steel tubular concrete column construction |
