The Wesu high-speed railway bridge across the Beijing-Hangzhou Grand Canal is fully closed

China News Service, Nanjing, October 12 (Xu Wenfeng, Hu Ruiqi, Zhu Xiaoying) China Railway Shanghai Group Co., Ltd. announced on the 12th that the steel truss arch bridge of the Wesu high-speed railway (hereinafter referred to as the Wesu high-speed railway) across the Beijing-Hangzhou Grand Canal was closed in Suqian, Jiangsu on the same day, marking the completion of the entire bridge of the Wesu high-speed railway across the Beijing-Hangzhou Grand Canal. As a result, a key breakthrough was achieved in the construction of the superstructure of the main bridge, laying a solid foundation for the subsequent construction of ancillary works on the bridge deck system.

The large bridge across the Beijing-Hangzhou Grand Canal is constructed and managed by the Nanjing Railway Hub Project Construction Headquarters of China Railway Shanghai Bureau Group Co., Ltd., designed by China Railway Fourth Survey and Design Institute Group Co., Ltd., and constructed by China Communications Construction Company Second Navigation Engineering Bureau Co., Ltd. It is one of the controlled projects of the Wesu High-speed Railway. The main bridge spans the Beijing-Hangzhou Grand Canal with a main span of 300 meters and a total length of 461.1 meters.

Yang Haisheng, the project leader of CCCC Second Navigation Engineering Bureau Co., Ltd., introduced that the construction of this arch rib closure combines multiple difficulties such as restricted water areas, strict temperature control, and multiple intersecting processes. The construction team adopted precise temperature window locking and fine fulcrum positioning construction techniques to collect real-time data. Collect data such as ambient temperature, arch rib temperature, closing gap, height difference, axis deviation and other data to lock the operation timing; complete component attitude adjustment and precise alignment in stages, control various deviations of the closing within 5 mm, and complete component consolidation, on-site welding and other processes with high quality.

The Wesu High-speed Railway is an important part of the auxiliary channel of the Beijing-Shanghai High-speed Railway. It is connected to the Tianjin-Weifang high-speed railway under construction, the Jinan-Qingdao high-speed railway, the Xuzhou-Yancheng high-speed railway, and the Rizhao- Lankao high-speed railway that have been opened and operated. The main line of the Weisu High-Speed ​​Railway is approximately 399 kilometers long with a design speed of 350 kilometers per hour. The line leads from Weifang North Station in Weifang City, Shandong Province, passes through Rizhao City, Linyi City, Shandong Province, Xuzhou City, Jiangsu Province, and ends at Yanghe North Station in Suqian City, Jiangsu Province. There are 12 Weifang North and other stations on the entire line.

After the completion of the Weisu High-speed Railway, Linyi, Shandong and Suqian, Jiangsu will enter the "Beijing-Shanghai High-speed Railway 2-hour traffic circle", which is of great significance to promoting the coordinated development of regional economies in southern Shandong and northern Jiangsu and Jiangsu.
