en.Wedoany.com Reported - In late May, with the pouring of the final cubic meter of concrete, the turnout continuous beam of the Shangzhou Super Major Bridge on the Pingluozhou High-Speed Railway, constructed by China Railway Tenth Bureau, was completed and successfully closed, marking significant progress in the project's control works and laying the foundation for the full-line girder erection passage.
As a critical bifurcation node transitioning from one line to three lines, the turnout is a key control project of the Shangzhou Super Major Bridge. The quality of the beam pouring directly affects the alignment and structural safety of the entire bridge. The combined support cast-in-place continuous beam completed in this pouring is located between piers No. 773 and No. 784 of the Shangzhou Super Major Bridge, with a total beam length of 357.6 meters, a top width linearly varying from 12.6 meters to 25.9 meters, and a bottom width linearly varying from 6.7 meters to 18.82 meters.
The turnout beam features a complex structure, large volume, and long span, resulting in high construction difficulty and intricate procedures. Facing complex construction conditions and stringent construction standards, the project team of China Railway Tenth Bureau fully implemented standardized and normalized construction management requirements, tailored a special construction plan based on actual site conditions, continuously optimized construction processes and technical details, refined the logical relationships of core procedures such as concrete pouring, prestressing tensioning, and system conversion, and improved on-site operational efficiency. They established a data collection system for foundation settlement, support deformation, concrete temperature control, and prestressing tensioning, enabling real-time data upload and anomaly alerts, forming a full-process construction archive. This ensured precise control and compliance of all construction parameters, providing technical support for high-quality beam pouring and meeting the requirements of the lifelong quality responsibility system for high-speed railway projects.
The Pingluozhou High-Speed Railway is a vital component of the national comprehensive three-dimensional transportation network backbone. Upon completion, the project will achieve one-hour connectivity among Pingdingshan, Luohe, and Zhoukou cities, with a half-hour direct reach to the core area, opening up the interconnection channel between the western Henan corridor of the Hohhot-Nanning High-Speed Railway and the Zhengzhou-Fuyang High-Speed Railway, thereby constructing a convenient "golden corridor" linking the central and western regions with the Yangtze River Delta.
