Modular construction method for porous large-span frame-structure bridge to pass through existing railway underneath
The invention provides a modular construction method for a porous large-span frame-structure bridge to pass through an existing railway underneath. The modular construction method comprises the following steps that the frame-structure bridge is modularly decomposed into a plurality of frame-structure bridge sections; each frame-structure bridge section is prefabricated; a D-shaped auxiliary beam is adopted to reinforce the line; and a combined synchronous jack is adopted to conduct jacking construction on all the frame structure bridge sections. Modular construction is achieved, construction quality is improved, procedures are simplified, the construction period is shortened, and construction safety is guaranteed.
本发明提供一种多孔大跨度框构桥下穿既有铁路模块化施工方法，包括如下步骤将框构桥模块化分解为多个框构桥节段；对各个所述框构桥节段分别预制；采用D型便梁加固线路；采用组合同步千斤顶对各个所述框构桥节段顶进施工。本发明实现模块化施工，提高施工质量，简化工序，缩短施工工期，保证施工安全。
