Closure of continuous beam of tie bar arch with the largest span of lianxu high speed railway
This website (Li Jiao) at 10 a.m. on December 18, 2019, with the completion of the last segment of the arch rib assembly, the continuous beam of the largest span tied arch of lianxu high-speed railway in Donghai County, Lianyungang City, Jiangsu Province was successfully closed, marking the smooth closure of the first constant cross-section tied beam of China's 350 km / h high-speed railway with a span of 168 m tied arch, which has written a heavy color for the history of China's high-speed railway construction. Liang Xuejun, director of the project Department of the former section II of
Lianyungang Xuzhou high speed railway station, introduced that the main line of Lianyungang Xuzhou high speed railway is 180.385km long, with a design speed of 350km / h, starting from Lianyungang station in the East and ending at Xuzhou East Station in the West. The main bridge of Donghai super large bridge of lianxu high speed railway, which is constructed by Beijing Engineering Bureau of China Railway, spans G311 National Highway (40 + 168 + 40) m and is located at the junction of Donghai County and Xinyi City, Jiangsu Province. The arch rib is of concrete-filled steel tube structure and adopts the composite arch section type. The included angle of the line is 19 ° and the total length is 248.7m. The bridge is the first time in the history of China's 350 km / h high-speed railway construction to adopt a continuous beam with constant cross-section and a span of 168 m tied arch. It is also one of the key control projects of the whole line of Lianyungang Xuzhou railway, and is the first of its kind in China's high-speed railway.
with the approval of Lianyungang Area of Jiangsu Free Trade Zone, Lianyungang Xuzhou high speed railway will become an important platform for Lianyungang to build an important international transportation hub in Asia and Europe, and provide important transportation infrastructure support for Lianyungang to achieve high-quality development, and later to arrive first.
