Method for dismantling under-crossing railway frame bridge without interrupting traffic
The invention discloses a method for dismantling an underpass railway frame bridge under the condition of not interrupting traffic, which comprises the following steps of: dismantling the frame bridge in pairs, firstly closing a half frame bridge road, enabling the other half frame bridge road to pass normally, sequentially and repeatedly cutting the closed frame bridge in blocks, and then sequentially sliding and dragging the frame bridge to the outside of a line in blocks. And closing the other half frame bridge according to the mode, and dismantling according to the same method until dismantling construction of all the frame bridges is completed. The method solves the problem that the safety risk of dismantling the underpass railway frame bridge is high, guarantees the traffic smoothness in the early stage of the highway, and accelerates the dismantling efficiency so as to reduce the influence on a business line and the highway.
本发明公开了一种不中断交通条件下下穿铁路框架桥拆除方法，包括：分副拆除框架桥，先封闭其中半幅框架桥道路，另外半幅框架桥道路正常通行，依次重复分块切割已封闭的框架桥，然后再依次分块滑移牵引至线路外，直至完成已封闭半幅框架桥的拆除，按照上述方式封闭另外半幅框架桥，按照同样的方法拆除，直至完成所有框架桥的拆除施工。本发明解决下穿铁路框架桥拆除安全风险高的难题，保障公路前期的交通畅通，加快拆除效率，以减少对营业线和高速公路的影响。
