Baocheng Railway Qingbaijiang Bridge Reconstruction Project is opened to traffic

After nearly two years of unremitting efforts through the Chengdu Construction Headquarters of Chengdu Group Co., Ltd., on July 1, Baocheng, a company under the establishment of a company of the 17th Bureau of China Railway and the supervision of the Chengdu Bureau Group Co., Ltd. The reconstruction project was successfully completed and opened to traffic, ensuring the smooth operation of the "Belt and Road" Central and EU trains.

The Qingbaijiang Bridge of the Baocheng Railway and the Chengwen Railway was founded in the 1950s. The standards were low and the foundation was shallow. The bridge pier was affected by the 2008 Wenchuan Earthquake, the impact of floods and iron ships in 2013. Transportation is safe. Half a century later, the "relay" of the rebuilding project of the Baocheng and Chengwen Line Qingbaijiang Bridge was demolished at the original site.

The project is located in Chengdu and Deyang City, Sichuan Province. The reconstruction of the three bridges adopts a special structure of the paddling groove beams, with a total length of 139.4 meters in the railway bridge. In order to ensure the normal traffic of the existing Baocheng and the Chengwen Railway, the three bridges were rebuilt in three stages. From November 2020 to September 2021, the first step of Baocheng was around the text line to remove the Qingwen Line Qingbaijiang Bridge. ; From October 2021 to June 2022, it was used to use the Chengwen Line to bypass Baocheng on the line. On the evening of the 30th, the three -stage station was renovated. After nearly 9 hours of the "sunroof point", more than 600 people fought overnight to restore the operation of the upper and lower lines and the original line of Chengwen Line. The entire project involves the transformation of the signal engineering of Qingbaijiang Station and Guanghan Station, the construction of communication engineering, the relocation of power engineering, and the demolition and new reconstruction of the contact network project. The construction is difficult and the safety risks are high.

The Qingbaijiang Bridge of Baocheng Line is 10m in the shortest business line. The traffic of Pocheng Line passenger and cargo trains is large. The trail distance is less than 2m. The bridge construction is carried out to ensure the normal line and power supply transportation, the construction difficulty and the risk of operation. Chengdu Construction Headquarters organized design, construction, supervision and other units to carefully discuss construction difficulties, strictly implement grid management, and allocate safety protection personnel in accordance with the requirements of "one machine, one protection", refine the division of labor, compact responsibilities, precisely define equipment accurately, and define equipment accurately. Location, lines, and operation angles, strictly adhere to the security red line. The original design of the Qingbaijiang Bridge adopts the overall full -length Bei Liang slot type paddling beam construction. After fully demonstrating, the span of the beret beam bracket "removes" and "takes" the short, effectively shorten the construction period, ensure circulating use, greatly greatly use it, greatly greatly use it. Reduce the risk of business line construction.

As a key project in Sichuan Province, the reconstruction of the Baocheng Railway and the Chengwen Railway Qingbaijiang Bridge will greatly improve the ability to flood, eliminate hidden safety hazards and ensure the safety and smoothness of the North -Owan freight channel, and facilitate the better of Chengdu, Wenchuan, Xi'an, and Xi'an. Communication, its completion is of great significance for the construction of the “Belt and Road” and the construction of the Economic and Technological Development Zone of the Chengdu International Railway Port.
