On October 21, the Yong County Beiliu River Grand Bridge, the largest continuous beam segment of the Yucun Railway, successfully completed its key mid-span connection (70+125+70 meters). This marks a significant milestone in the ongoing construction of the Yucun Railway.
The Beiliu River Grand Bridge spans 1,447.82 meters, featuring a main span of 125 meters supported by piers 12 and 13. The construction employs a cantilever casting method, making it the longest continuous beam crossing water and the deepest underwater bridge along the entire route.
Mid-span connections play a crucial role in bridge construction, significantly impacting the overall structural integrity and alignment. To ensure safe and efficient progress on the bridge, the Guangxi Transportation Investment Group and Nanyue Railway Company collaborated with the Nanning Railway Engineering Construction Command to continuously optimize their construction plans and ensure proper resource allocation.
The construction team, including China Railway No. 4 Engineering Group’s Nanzhu High-Speed Railway Yucun segment project department, established specialized technical and safety teams. They enhanced construction organization, improved quality control, and conducted thorough safety risk assessments. Additionally, they utilized pre-pressurized water buckets to adjust the elevation at both ends of the connection, ensuring precise alignment for the large-span continuous beam.
The Yucun Railway, an extension of the Nanyue Railway, is designed for a speed of 350 kilometers per hour over a total length of 111 kilometers. It will introduce two new stations: Yong County South and Cengxi East.
Upon completion, the project will establish a two- to three-hour transportation circle connecting Nanning with the Guangdong-Hong Kong-Macao Greater Bay Area, significantly enhancing the capacity of the “Two Guang” passage and filling critical gaps in the regional transport network, thereby driving economic development along the route.
