摘　　要：为了解决在跨运营铁路线等复杂施工环境下无法在现场进行施工的问题,设计了可调式移动支撑门架系统,其核心技术突破施工难点。实现了在狭窄的走廊带与骑行运营铁路线保障安全的基础上桥梁施工,降低施工安全风险,经实际应用,达到减少材料消耗、保障安全、缩短工期、提高施工效率和降低人工成本等良好效果。In order to solve the problem that construction cannot be carried out on site in complex construction environments such as cross-operating railway lines,an adjustable mobile support gantry system is designed,and its core technology breaks through the construction difficulties.It realizes bridge construction on the basis of ensuring safety in narrow corridor belts and cycling operation railway lines,reduces construction safety risks,and achieves good effects such as reducing material consumption,ensuring safety,shortening construction period,improving construction efficiency and reducing labor costs through practical application.
