Recently, a 10,000-ton bridge in Shanghai successfully completed a pivotal rotation maneuver, precisely spanning the Shanghai Maglev Demonstration Operation Line—the world’s first commercially operated high-speed maglev railway. Utilizing advanced horizontal rotation technology, the construction team rotated a pre-assembled bridge segment into place within approximately 70 minutes, achieving a near-90-degree turn without disrupting regular maglev operations—ensuring ‘zero interference’ with existing infrastructure. The bridge, a critical component of an urban expressway project, spans about 120 meters. To guarantee safety and millimeter-level accuracy, engineers employed BIM modeling, real-time monitoring systems, and high-precision surveying instruments throughout the operation. This successful rotation not only demonstrates China’s engineering prowess in executing complex infrastructure projects within dense urban environments but also sets a valuable precedent for future similar endeavors, marking a significant step forward in intelligent construction and sustainable engineering practices.
近日，一座重达万吨的桥梁在上海成功完成转体施工，精准跨越世界首条商业运营的高速磁浮线路——上海磁浮示范运营线。此次转体工程采用先进的水平转体技术，在确保磁浮列车正常运行的前提下，将预制完成的桥梁结构在短时间内旋转到位，实现了对既有交通设施‘零干扰’的跨越。该桥梁是某城市快速路的关键控制性节点，全长约120米，转体角度接近90度，整个过程仅耗时约70分钟。为保障安全与精度，施工团队运用BIM建模、实时监测系统和高精度测量设备，对转体过程进行全方位控制。此次成功转体不仅展现了中国在复杂城市环境下大型桥梁建设的技术实力，也为今后类似工程提供了宝贵经验，标志着我国在智能建造与绿色施工领域迈出了坚实一步。
