Following the end of the heat of summer, major project constructions are persistently advancing across the country. It has been reported that as construction progresses steadily, several high-speed rail projects have achieved new milestones.
Major Achievements in Inner Mongolia: In Inner Mongolia, the completion of Pier 1 marked a significant milestone for the lower structure of the Shadongqing Extra Large Bridge on the Yinhua-Yinba Branch Line of the Baoyin High-Speed Rail. This achievement by China Railway 15th Bureau Group signals substantial progress in the bridge’s construction, providing a strong foundation for the upper structure and beam installation.
Han Wei, the project leader of China Railway 15th Bureau Group, stated that the Shadongqing Extra Large Bridge, measuring 1953 meters in length, is the longest bridge on the Inner Mongolian section of the Yinhua-Yinba Branch Line. In a commitment to ecological conservation, the project employed innovative approaches such as transplanting endangered sand shrubs and protecting slopes along the route, demonstrating a high-quality “green engineering” endeavor.
Milestone in Shaanxi Province: In Shaanxi, at the construction site of Tianzhu Mountain Tunnel No.1 on the West-Tenth High-Speed Rail, China Railway 11th Bureau Group has successfully advanced the tunnel boring and concrete pouring operations. The tunnel excavation has now exceeded 2500 meters.
The Tianzhu Mountain Tunnel No.1, approximately 14.7 kilometers long, poses a technical challenge in the construction of the West-Tenth High-Speed Rail. According to Liu Hanliang, the project leader of China Railway 11th Bureau Group, innovative methodologies have been employed, including simultaneous excavation from nine faces and the application of more than 20 novel processes and equipment, ensuring a smooth progression of the tunnel construction.
Upon the completion and operation of the West-Tenth High-Speed Rail, the travel time from Xi’an to Shiyan will be reduced to within one hour, and from Xi’an to Wuhan to approximately 2.5 hours. This development will play a pivotal role in boosting rural revitalization in the Qinba Mountain area and driving economic growth along the rail route.
Advancing Chongqing’s Rail Network: In Chongqing, the construction of the Gao Sheng Tunnel No.1 on the Xiyu High-Speed Rail’s Kangyu section is progressing steadily. The main structure of the tunnel entrance has been completed, and the core construction work continues in an organized manner.
Xu Zhigang, the project manager of China Railway 17th Bureau Group, introduced that the Gao Sheng Tunnel No.1, spanning 8392 meters, is situated within the Luo Jia Zhai Gas Field Area of Gaoqiao Town, Kaizhou District, Chongqing. Due to the challenging conditions involving gas emissions, the construction requires substantial attention to safety.
The Xiyu High-Speed Rail is a significant component of China’s “Eight Vertical and Eight Horizontal” high-speed rail network, serving as a crucial link between the Jing-Kun Passage and the Bao (Yin) Sea Passage. Once operational, it will be connected to various existing lines, including the Chengdu-Chongqing High-Speed Rail and the Zhengzhou-Chongqing High-Speed Rail, further enhancing the transportation infrastructure in central and western regions.
Progress in Hubei Province: In Hubei, the construction of the Shaganghe Reservoir Extra Large Bridge on the Xiangjing High-Speed Rail, undertaken by China Railway 15th Bureau Group, reached a significant milestone with the completion of the first continuous box girder pouring. This event marks the initiation of upper-structure construction for all 69 bridges along the rail line, setting a solid foundation for the timely completion and operation of the entire line.
Yang Li, the project leader of China Railway 15th Bureau Group, elaborated that the Shaganghe Reservoir Extra Large Bridge spans 1766 meters and represents one of the most challenging engineering projects along the line. The Xiangjing High-Speed Rail connects Xiangyang City and Jingmen City in Hubei Province, with a total length of approximately 117 kilometers. It is a vital component of the national “Eight Vertical and Eight Horizontal” high-speed rail network. The project features numerous bridges and tunnels, with bridges accounting for about 84.7% of the total, including 69 newly constructed bridges measuring approximately 77 kilometers in total length.
Advancements in Zhejiang Province: In Zhejiang, at the Wenzhou Precast Yard of China Railway 24th Bureau Group, the first precast concrete box girder for the Wenzhou to Yuhuan section (Wen-Yu Railway) of the Hangzhou-Taipei High-Speed Rail has been successfully poured. This achievement signifies a new breakthrough in the construction of the Wen-Yu Railway, accelerating the overall construction progress.
