Recently, the mid-span closure of the continuous beam of the Yinjiang River Bridge on the Dali-Ruili Railway Project undertaken by the First Company of China Railway 23rd Bureau Group was successfully completed.

　　The continuous beam of the Yinjiang River Bridge is a large-span cantilever box girder with high construction difficulty and technical content. During construction, the project department organized carefully and managed scientifically, continuously adjusted progress management methods and means, optimized construction plans, coordinated arrangements, strictly followed specifications and design requirements, and conscientiously carried out linear control, tensile stress monitoring, and system conversion of the cantilever box girder. While ensuring safety and quality control, they continuously accelerated construction progress to ensure safe and efficient completion. Now, the main construction of the 3-span continuous box girder of the Yinjiang River Bridge has been fully completed.

　　The completion of the continuous box girder construction of the Yinjiang River Bridge marks a key step forward in the full connection of the Dali-Ruili Railway. In subsequent construction, the Dali-Ruili project will continue to strengthen safety and quality management, optimize construction organization, accelerate progress, and resolutely win the critical battle of 2020.
