Baoding, Hebei ¡ª On February 1, at the Xiong¡¯an¨CXinzhou High-Speed Railway super major bridge spanning the Beijing¨CGuangzhou Railway in Shunping County, Baoding City, Hebei Province, employees of China Railway No.3 Engineering Group steadily and accurately laid the first pair of 500-meter-long rails onto the ballastless track bed, marking the official commencement of the track-laying phase for the Xiong¡¯an¨CXinzhou High-Speed Railway.
The Xiong¡¯an¨CXinzhou High-Speed Railway is a key component of China¡¯s Eight Vertical and Eight Horizontal high-speed railway network, forming part of the Beijing¨CKunming corridor. The line starts at Xiong¡¯an Station in Hebei Province and terminates at Xinzhou West Station in Shanxi Province, with a mainline length of approximately 342 kilometers and a design speed of 350 km/h. Track-laying operations span Hebei and Shanxi provinces, with a total track-laying length of 716 kilometers and the installation of 147 sets of turnouts. According to the construction plan, track laying commenced on February 1 on the Hebei section, followed by subsequent operations on the Xiong¡¯an¨CBaoding section and the Shanxi section.
As bridges and tunnels account for 88% of the entire line, multiple tunnel sections feature continuous long steep gradients of up to 30¡ë, posing significant challenges for long-rail transportation and locomotive braking and greatly increasing construction difficulty. Meanwhile, track connection works at Xiong¡¯an Station and Xinzhou West Station also face multiple challenges, including high safety risks, technical complexity, and short maintenance window?durations.
To ensure the safe, high-quality, and efficient advancement of track-laying works, the project team of China Railway No.3 Engineering Group carried out specialized training on construction safety management to strengthen safety awareness among all participants. Detailed plans for long-rail transportation and installation were meticulously prepared, with strict control over technical standards and safety quality. A total of 15 locomotives, 8 rail vehicles, 4 sets of long-rail frames, and 2 track-laying machines were deployed. In addition, an information-based track-laying system was actively applied, enabling real-time remote monitoring of the operating status of track-laying machines, long-rail transport vehicles, and rail-welding locomotives, thereby laying a solid foundation for safe and efficient track-laying operations.
