Start up static acceptance of Huaian Zhenjiang section of Lianzhen high speed railway

On July 15, the static acceptance of the Huaian Zhenjiang section of Lianzhen high-speed railway constructed by China Railway Shanghai Bureau Group Co., Ltd. was officially launched, laying a solid foundation for the completion and operation of the whole line on schedule.

The Lianyungang Huaian section of the Lianyungang Huaian high-speed railway is located on the north-south axis of Jiangsu Province. Huaian Zhenjiang section has a total length of about 200 km, and three tie lines with a total length of 20.77 km and a design speed of 250 km / h. There are 9 stations and 3 line posts along the whole line.

According to the person in charge of the project of China Railway Shanghai Design Institute Group Co., Ltd., the huaizhen section of Lianzhen high-speed railway has many "innovation cards": Wufengshan Yangtze River Bridge is the first highway railway suspension bridge in China, the first suspension bridge for high-speed railway in the world and the largest load-bearing suspension bridge for both highway and railway. The swivel bridge on the left line of Tai'an town connecting line across Ningqi railway is in China It is a railway swivel bridge with the largest single track railway span, the smallest curve radius, the closest distance to the existing line and the largest slope.

They opened up new ideas to solve the problem of connecting the new high-speed railway to the existing line stations, creatively adopted the first domestic station type of "main line outsourcing and yard semi longitudinal" to minimize the impact on the existing lines; they studied new topics, combined with the working conditions of the kilometer span suspension bridge of Wufengshan Yangtze River Bridge, designed the alignment and track structure of the bridge section, and simulated and demonstrated The change trend and critical point under various extreme temperature and wind conditions are described, which provides important reference for the subsequent research, design, construction and operation of Long-span Railway suspension bridges. In the new enabling scenario, the comprehensive application research of BIM Technology with track as the main body is carried out in the whole railway, and the landform scene of the line and station yard is taken as the edge, and the subgrade and bridge works under the track line are mainly realized It is a large-scale entity BIM integrated supporting technology application, which is linked by the "four electric" equipment engineering on the track line and integrated with the station building square on the side of the track line.

Lianzhen high-speed railway is a national key infrastructure construction project. It is an important part of the national rapid railway network, the Yangtze River Delta inter city network and the "four vertical and four horizontal" railway network of Jiangsu Province. It has an important function as an auxiliary channel of Beijing Shanghai high-speed railway. After the completion of the line as a whole, it will realize the rapid connection between the northern and central Jiangsu areas and the core cities such as Shanghai and Nanjing, which is of great significance for driving the industrial and economic development of the regions along the line and promoting the high-quality development of the Yangtze River Delta integration.
