Abstract：
Intermediate column project of the Cultural Center station, which is a transfer station between Tianjin subway lines Z1 and 5, adopts one-off positioning and installation technique of underwater deep hole steel pipe column, and various critical techniques are used, such as concrete pouring after geographical coordinate positioning, bottom concrete pouring in steel pipe column and lifting of steel pipe column, etc. One-off positioning and installation technique of underwater deep hole steel pipe column doesn't need slurry pumping and drainage and setting of steel retaining cylinder, so it successfully realize simplified construction process, short construction schedule and low construction costs.
