Core Insights - The successful rotation of the Wanjiazui Bridge, a key component of the Shuangliu Yangtze River Bridge project, marks a significant milestone in the construction process, laying a solid foundation for the project's completion [1][3] Group 1: Project Overview - The Wanjiazui Bridge, with a total length of 407.236 meters, features a separated design and is constructed using a 2×70 meter prestressed concrete T-shaped rigid frame [1][3] - The bridge is part of the G9906 Wuhan Urban Circle Ring Road, which will significantly reduce travel time from 1.5 hours to approximately 5 minutes between Xinzhou District in Wuhan and Ezhou [3] Group 2: Technical Innovations - The project team overcame technical challenges such as the bridge's heavy weight and curved layout by implementing multiple technological innovations, including a self-developed real-time monitoring system for the bridge rotation process [3] - The use of BIM modeling technology allowed for a significant reduction in the optimization cycle for the counterweight plan from 3 days to 1 day, enhancing preparation efficiency [3] Group 3: Construction Techniques - An innovative support system combining full scaffolding and Bailey beams was employed to address the challenges of supporting large-span cast-in-place beams under complex geological conditions [3] - The application of an adjustable prefabricated support system improved construction efficiency and material turnover while significantly reducing safety risks during construction near the operational railway [3]

Core Points - The Wanjiayu Bridge, a key project funded by Hubei Jiaotou Group and constructed by China State Construction Engineering Corporation, successfully completed its rotation, allowing it to cross the busy Wuhuang Railway with minimal disruption to rail transport [3][9]. - The bridge, measuring 407 meters in length and featuring a prestressed concrete T-shaped rigid frame, is designed to enhance the transportation network in the Wuhan metropolitan area [9][13]. - The completion of the bridge is expected to significantly reduce travel time from Xinzhou District in Wuhan to Ezhou from 1.5 hours to just 5 minutes, thereby improving regional traffic efficiency [13]. Technical Innovations - The construction team overcame technical challenges related to the bridge's weight and curvature through multiple innovations, including the development of a real-time monitoring system for the bridge's rotation [9]. - This system allows for automated monitoring of the bridge's posture and structural stress changes during the rotation process, ensuring safety and precision [9]. Economic Impact - The New Port Shuangliu Yangtze River Bridge will enhance the connectivity between the Yangluo International Port and Ezhou Huahu Airport, as well as the Wuhan National Aerospace Industry Base and Optics Valley, creating an efficient linkage between aviation, ports, and industry [13]. - The bridge is part of the national expressway network G9906 and is expected to support the economic and social development of the surrounding areas by improving transportation infrastructure [9].
