At 16:16 on April 9, Fengtai Station Project Management Department of China Railway Beijing Bureau Group Co., Ltd. was responsible for the construction management and the construction of Fengtai station reconstruction project of Beijing Railway Terminal undertaken by China Railway No. The arch bridge is the first six line simply supported steel box arch bridge in China, with the shape of "six colors rainbow", adding another beautiful scenery to Beijing. The arch bridge is located in the south of Zhengyang bridge, Fengtai District, Beijing. It spans the existing Beijing Shanghai line, with a span of 112 meters and a width of 38.6 meters. It is the first domestic arch bridge to adopt the six line layout of 4 railway lines between the ribs and 1 railway line outside the ribs. In order to ensure the normal operation of the existing railway, the steel box arch bridge adopts the overall construction scheme of non bridge position assembly, longitudinal step-by-step pushing to the designed bridge position, and beam dropping to complete the system transformation. The project management department of Fengtai station works with the participating units to do a good job of epidemic prevention and control and resumption of production. In only 7 days, the 5700 ton bridge was pushed 112 meters to the west, successfully completing the construction task of the bridge crossing the Beijing Shanghai line and the Beijing Guangzhou line. After the reconstruction of Fengtai station, with a total construction area of 398800 square meters, it is the first railway hub in China to adopt the design of ordinary speed and high-speed double deck yard, with 17 sets of 32 lines, integrating various modes of transportation such as high-speed railway, ordinary speed railway, highway and subway.
