| Abstract: | This article took the Sunxi River Bridge as an example, summarized main construction procedures of ribs vertical transfer on steel box-concrete composite arch bridge, and analyzed the main stages in construction process, such as vertical assembly of steel box, the set up of vertical rotating hinge, swivel construction of steel box, and close of steel box. We also discussed the key construction technologies in assembly line adjustments and docking of the steel box segments. |
