上跨既有铁路混凝土拱桥拆除施工技术

The construction technology of concrete arch bridge demolition across existing railway

通过上跨既有铁路混凝土拱桥拆除施工实例,介绍了采用静力切割工法结合钢桁架梁吊运设备,在铁路封锁点内拆除混凝土拱桥的施工技术,实践证明:该施工技术无震动、无灰尘、无噪声,且安全、高效、环保,具有良好的经济效益和社会效益。

Through the construction examples of concrete arch bridge demolition across existing railway, this paper introduced the construction technology of concrete arch bridge demolition into railway lock-up point using static cutting method and combining with steel truss beam handling appliances, the practice proved that, the construction technology no vibration, no dust, no noise, and safe, efficient, environmental protection, had good economic benefit and social benefit.
