The main line of Yantong high speed railway is successfully laid

On the morning of August 7, at the construction site of Nantong west station of Yancheng Nantong high-speed railway, the last group of 500m long rail was laid in place, marking the smooth laying of the main line of Yancheng Nantong high-speed railway. Next, the project will enter the static acceptance stage orderly.

The whole line of Yantong high-speed railway is laid with 500m long rail, which is designed as one-time laying and inter regional CWR. Since the first rail laying in this year, Yantong Railway General Contracting Project Department of China Railway Design Group Co., Ltd. has optimized the construction organization according to the node construction period, and reasonably allocated human and material resources. The maximum daily track laying amount of a single machine reaches 16.5 km. Subei railway engineering construction headquarters of Shanghai Bureau of China Railway Group Co., Ltd. overcame the adverse factors of epidemic situation and excessive rainfall, comprehensively strengthened the project construction management, scientifically optimized the construction scheme, increased the input of personnel, equipment and materials, adopted the construction organization mode of "two sets of track laying machines + two sets of long track transportation equipment", and worked in double shifts in turn to effectively promote the track laying construction.

Yantong high-speed railway is an important part of the main channel of "eight vertical and eight horizontal" high-speed railway in China's medium and long-term railway network planning, and is an important transportation facility to help the "belt and road" construction and the development of the Yangtze River economic belt. The total length of the main line of the line is 156.6 km, and the design speed is 350 km / h. After completion, it will facilitate the interconnection and interworking between Xuyan and Shanghai, and form a convenient transportation channel connecting North China, Northwest China and Yangtze River Delta. It will play an important role in improving the overall transport capacity of coastal railway corridor, improving the radiation efficiency of regional road network, and promoting the regional integrated development of the Yangtze River Delta.
