Southeast Asia Information Port News (www.dnyxxg.com) – In the early hours of the 17th, with the completion of the final concrete pour, the main span of the continuous beam arch bridge across the Haoziwei flood diversion ditch on the Nanjing Grand Bridge of the Shanghai-Nanjing-Hefei High-Speed Railway was successfully closed, marking a new milestone in the Nanjing hub project and accelerating construction.
The continuous beam that was successfully closed is located in the Haoziwei flood storage area at the border of Jiangsu and Anhui provinces. The main beam is 346.1 meters long, making it the longest continuous beam arch bridge on the entire Nanjing hub project of the Shanghai-Nanjing-Hefei High-Speed Railway. Wen Jinhua, Deputy Secretary of the Party Branch of the Nanjing Hub Project of the Shanghai-Nanjing-Hefei High-Speed Railway under China Railway Shanghai Engineering Bureau, explained that the project construction team leveraged technology to empower construction, applying new technologies to continuous beam positioning, heat-shrink sealing, intelligent tensioning, and automatic grouting, thereby improving project quality and efficiency.
As an important component of China's "Eight Vertical and Eight Horizontal" high-speed railway network along the Yangtze River, the Shanghai-Nanjing-Hefei High-Speed Railway is the eastern section of the Shanghai-Chongqing-Chengdu High-Speed Railway. It starts from the newly built Shanghai Baoshan Station in Shanghai, passing through Suzhou, Nantong, Taizhou, Yangzhou, and Nanjing in Jiangsu Province, and Chuzhou and Hefei in Anhui Province, before connecting to the existing Hefei South Station. The line is approximately 554 kilometers long, designed for a speed of 350 kilometers per hour, and has 16 stations.
The Shanghai-Nanjing-Hefei High-Speed Railway is a crucial hub connecting the east and west of the national high-speed railway network, a major project in the construction of the Yangtze River Economic Belt's comprehensive transportation hub, and a key node in Nanjing's construction of a "rice-shaped" high-speed railway network directly connecting to the rest of the country. Upon completion, the project will be of great significance to building a "rail-based Yangtze River Delta" and optimizing the railway network layout along the Yangtze River. (End)
