万吨巨梁“轻盈转身”跨越铁路 双柳长江大桥冲刺年底建成

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].
