| Abstract: |
The 4th Ring Transportation Corridor in Zhengzhou, Henan, China (the Project) is implemented in accordance with the design scheme of integral bridge structures and the short-line match casting method. This paper focuses on key technologies of segment precasting used in the Project, involving the design and layout of precast yards, the formwork design for precast segments and the geometry control in the precast yards as well as the application of information technology in precast yards. It can be used as references for projects related to precast segment production in the industry. |
