The Ningxia section of Yinxi high speed railway has been completed, Gansu section and Shaanxi section are advancing as planned

The reporter noted that according to the article released on October 16 by the official wechat public account of China Railway Construction Co., Ltd. "China Railway Construction", the Ningxia section of Yinxi high speed railway designed and constructed by China Railway Construction Co., Ltd. has been successfully completed, and the Gansu section and Shaanxi section are advancing as planned.

the above article states that Yinxi high speed railway is an integral part of the "eight vertical and eight horizontal" package (yinhaitong) road in China's medium and long-term railway network planning, which connects the Yellow City belt and Guanzhong Tianshui Economic Zone. The line is led from Yinchuan Station of Ningxia and led to Xi'an North Station of Xi'an hub. The total length of the main line is about 617 kilometers, the design speed is 250 kilometers per hour, there are 20 stations in total, and the total length of bridges and tunnels is 394.3. Km, accounting for 63.9% of the line length. Yinxi high speed railway is the overall survey and design of China Railway Construction First Design Institute. China Railway 11th bureau group, China Railway 12th bureau group, China Railway Construction Bridge Bureau Group, China Railway 14th bureau group, China Railway 16th Bureau Group, China Railway 19th bureau group, China Railway 21st bureau group, China Railway 22nd Bureau Group and China Railway Construction Electrification Bureau Group jointly undertake the Yellow River Bridge and Shuibei bridge of Yinchuan airport. For the construction tasks of key control projects along the whole line, such as cunjing River Bridge, Binxian tunnel, Gecun tunnel, Yima No.1 Tunnel, xinyongsuliang long tunnel, tieyiyuan participated in the supervision and tiesiyuan participated in the project consultation. As mentioned in the above article, Yinxi high speed railway runs through the whole loess plateau from north to South and passes through five geomorphic units, such as loess gully, Tableland and beam area, with extremely complex topographic and geological conditions. In the design, there are a lot of difficulties such as high pier and long-span bridge, large section and extra long loess tunnel, sand roadbed, collapsible loess, etc. the construction scale is large and the technical conditions are complex. The reliability of the project, the comfort of passengers and the rationality of economy need to be considered as a whole. The design work is faced with high difficulties and challenges. As mentioned in the above article, at present, Ningxia section of Yinxi high speed railway has been completed successfully, and Gansu section and Shaanxi section are advancing as planned. After the completion of the project, the history of no high-speed railway in Ningxia will be ended, so that the passenger train operation between Yinchuan and Xi'an will be reduced from 14 hours to less than 3 hours, and the large capacity and convenient channel connecting Ningxia inland open economic experimental zone and Guanzhong Tianshui Economic Zone will be opened at one stroke, and the Huangcheng city belt and Longdong area will be integrated into the national rapid transportation network through Xi'an hub, and the coal resources along the line will be increased. The construction of transportation and special branch lines provides a strong transportation capacity guarantee, which plays an important role in forming an all-round open pattern in inland areas, revitalizing the old revolutionary area of Shaanxi, Gansu and Ningxia, accelerating regional economic and social development, improving the layout of the road network in Northwest China, and promoting the construction of regional comprehensive transportation system.
