西十高铁西南联络线跨陇海铁路连续梁成功转体

Core Points - The successful rotation of the continuous beam across the Longhai Railway marks a significant milestone for the Xi'an East Station and the Southwest Liaison Line of the Xi'an to Ten High-speed Railway project, laying a solid foundation for subsequent engineering progress [2][3] Group 1 - The rotating bridge is a critical and challenging engineering component of the Xi'an to Ten High-speed Railway, being the only rotating bridge that crosses an operational railway line along the entire route [3] - The construction area for the rotation is only 5.3 meters from the safety boundary of the main line, presenting high safety risks and demanding precision in construction technology [3] - To ensure safety and precision during the rotation, the project team utilized BIM technology and software modeling to create a dynamic simulation of the entire rotation process [3] Group 2 - Prior to the official rotation, the project team conducted a trial rotation to collect and adjust parameters, optimizing the rotation process and enabling visual risk management [3] - During the official rotation phase, an information system was employed to monitor the real-time position, speed, and angle of the rotating structure, achieving millimeter-level precision in alignment with design requirements [3] - Comprehensive safety measures were implemented, including electronic intrusion radar barriers, vehicle warning systems, and fully enclosed protective canopies, ensuring a secure construction environment near the operational line [3]
