Core Viewpoint - The successful completion of the rotation construction of the Xumin Expressway overpass bridge marks a significant milestone for the project, laying the foundation for the overall opening of the expressway [1][3]. Group 1: Project Details - The Xumin Expressway overpass bridge spans 150 meters in length, 30.75 meters in width, and weighs 27,000 tons, consisting of six segments that were cast and then rotated as a whole [3]. - The bridge's rotation involved a counterclockwise turn of 71.3 degrees, achieving a total rotation angle of 85.3 degrees, with precise positioning over the Jingjiu Railway [3]. - The construction faced challenges such as high train traffic density on the Jingjiu Railway, limited working hours, narrow workspaces, high safety risks, and complex technical requirements [3]. Group 2: Construction Management and Innovation - Since its commencement in December 2023, the Xumin Expressway Company has adhered to a philosophy of high standards and efficiency, successfully overcoming multiple construction challenges [4]. - The project has implemented a "smart construction" approach, utilizing a construction engineering information system and enhancing safety management through a comprehensive four-dimensional approach [4]. - The Xumin Expressway single section is a crucial part of Shandong Province's 14th Five-Year Plan for highways, connecting key regions and improving the overall transportation network [4].
