Baocheng Railway Qingbaijiang Bridge Reconstruction Project is completed and opened to traffic

On July 1, the rebuilding project of the Baocheng Railway Qingbaijiang Bridge was successfully completed and opened to traffic, which greatly improved flood control. As one of the main lines of Sichuan Central and European trains, the completion of the bridge ensured the safety and smoothness of the north -headed Sichuan freight channel.

The Qingbaijiang Bridge of Baocheng 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, and there were major hidden safety hazards, which seriously affected transportation safety. 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 reconstruction project is located in Chengdu and Deyang City, Sichuan Province. The three rebuilding bridges adopt a special structure of the cast -in -law groove beams. Each railway bridge is 139.4m in length. In order to ensure the normal traffic of both Baocheng and Chengwen Railway, the three bridges were rebuilt in three stages. Two temporary detouring transition stools were used to transport transitions. After detouring, the existing railway was removed and the original bridge was rebuilt. The 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 network project.

According to Du Xuezhang, the commander of the Chengdu Construction Command of the Chengdu Bureau of China Railway, the Qingbaijiang Bridge was limited by the construction conditions at that time, and the foundation was not enough. question. The rebuilding project of the three bridges in Qingbaijiang, first, uses a 24 -meter -long pile foundation foundation to solve the problem of scouring. In addition, the original 12 -meter span beam to 30 meters has been expanded to completely solve the problem of hidden safety hazards during flood control. The rebuilding project of the Baocheng Railway Qingbaijiang Bridge is a key project in Sichuan Province. The Baocheng Railway and the Chengwen Railway will cross the river in Qingbaijiang Bridge. The completion of the reconstruction project will provide safety guarantee for the railway pass between Chengdu and Wenchuan and Xi'an.
