The latest news is that the Qingpu Extra-large Bridge section of the Shanghai-Suzhou-Lake Railway is located on the Yundang Lake at the junction of Shanghai and Jiangsu, with a construction length of 5.25 kilometers. At present, an average of three box girders are erected from Wujiang in Suzhou to Qingpu in Shanghai every day. It is estimated that all beam erecting operations in the Yaodang Lake will be completed in late June 2022.
In order to minimize the contact with water and protect the water body and wetland ecosystem of Yundang Lake, the construction unit innovated the construction scheme and adopted the form of "trestle+double-row steel pipe piles" cofferdam to cross Yundang Lake. This construction scheme of "reclaiming land from the sea" can not only speed up the construction progress, but also protect the water body to the greatest extent.
In addition, as the key and difficult control project of the entire Shanghai-Suzhou-Lake Railway, Shanghai Songjiang Cable-Stayed Bridge across the Inclined Pond Channel recently completed the hoisting of the first steel beam and the capping of the main tower. This is the first four-line ballastless track cable-stayed bridge with double-sided box-shaped steel-concrete composite beams for high-speed railway and ordinary railway in China. It has the characteristics of large live load, large eccentric load and complex load change, which requires extremely high line shape and stress state of the main girder.
At present, Jiangsu section and Zhejiang section of Shanghai-Suzhou-Lake Railway have entered the stage of box girder prefabrication and erection, and it is expected that the box girder erection task will be completed by the end of March next year.
Shanghai-Suzhou-Lake Railway starts from Shanghai Hongqiao Railway Station, passes through Suzhou City, Jiangsu Province, and ends at Huzhou Station, Huzhou City, Zhejiang Province. The total length of the main line is about163.8km, and the design speed is 350km/h.. There are 8 stations including Shanghai Hongqiao, Songjiangnan, Li Antang, Hu Fen, Shengze, Nanxun, Huzhou East and Huzhou Station.
Construction Significance After the completion and opening to traffic, the Shanghai-Suzhou-Lake Railway will become an important railway transportation channel connecting Shanghai, Suzhou, Huzhou and other cities. It can not only share the traffic pressure of Shanghai-Nanjing and Shanghai-Hangzhou corridors, but also facilitate the communication between Lishui, Liyang, Yixing and other cities and Shanghai, which is of great significance to promoting the integrated development of the Yangtze River Delta region and the economic and social development of southern Jiangsu.
