两万吨“巨无霸”凌空“转身” 新疆百里风区上演“空中芭蕾”

Core Viewpoint - The G30 Lianhuo Expressway Hatu Section expansion project features the largest rotating bridge in Xinjiang, utilizing innovative construction methods to minimize disruption to railway operations [1][2]. Group 1: Project Overview - The G30 Lianhuo Expressway Hatu Section expansion project spans 345 kilometers and is a key project in the national expressway network [2]. - The project includes the construction of a T-shaped continuous beam bridge that was rotated 61 degrees with millimeter-level precision, completed in 70 minutes [1]. Group 2: Construction Techniques - The project team overcame harsh weather and complex geological conditions by integrating information technology into construction processes, employing techniques such as 3D intelligent paving and unmanned compaction machinery [2]. - The use of the rotation method for bridge construction was chosen to avoid risks to railway operations and to ensure zero disruption during the construction phase [1]. Group 3: Significance - Upon completion, the expansion project is expected to significantly enhance regional traffic efficiency and contribute to the high-quality development of transportation in Xinjiang, as well as the overall national transportation network [2].
