Reporters learned from China National Railway Group Corporation on the 11th that from January to February this year, fixed assets investment in China's railways was 72.2 billion yuan, up 5.4% year on year. Railway construction was advanced in a high-quality and efficient manner, injecting new momentum into regional economic and social development. The relevant person in charge of the Construction Department of China Railway Group introduced that since the beginning of this year, China Railway Group has focused on serving major national strategies and regional economic and social development, leveraging the advantages of a long railway construction industry chain and wide radiation, making good use of the national "dual" support policies, and accelerating the promotion of railway construction. During the Spring Festival holiday, more than 570 construction sites of 46 key railway projects across the country continued to be under construction, with over 38000 construction personnel sticking to the front line. After the Spring Festival, efforts have been made to strengthen the organization of resuming work and production, enhance safety and quality, ecological environment protection, and engineering investment control. A number of key engineering projects have made positive progress. At the construction site of Qinhe Extra Large Bridge, a key and difficult project of Jiaoping High speed Railway, undertaken by China Railway 23rd Bureau in Henan, more than 200 builders are fully committed to promoting the pile foundation construction of the bridge. The Qinhe Grand Bridge has a total length of 11.99 kilometers and the longest pile foundation is 108 meters deep, making it the longest bridge pile foundation on the entire line. In Shandong, the second section of the Weisu High speed Railway Station, constructed by China Railway 14th Bureau, has fully resumed work after the holiday. The construction of the Weifang Extra Large Bridge, which spans the Weiqing Expressway and is a key and difficult project along the entire line, is steadily progressing, and the construction of the bridge substructure has been successfully completed. In Hubei, the Hujiawan Jushui Extra Large Bridge, a key and difficult project of the Hewu High speed Railway constructed by China Railway 18th Bureau, successfully closed its continuous beam across the Jushui River. The Hujiawan Jushui Extra Large Bridge has a total length of 13501 meters. Its continuous beams span the Jushui River and run parallel to the existing Hewu Railway, making construction difficult and posing high safety risks. The relevant person in charge of the Construction Department of China Railway Group stated that in the next step, China Railway Group will fully implement the key railway construction tasks determined in the "15th Five Year Plan", accelerate the construction of a world-class modern railway network, enhance the overall function and efficiency of the railway network, fully leverage the investment driving effect of railway construction, and provide strong support for serving the all-round expansion of domestic demand and promoting the high-quality development of China's economy and society.
