Large-span frame bridge undercrossing railway incremental launching construction method
The invention discloses a large-span frame bridge undercrossing railway incremental launching construction method. The method comprises the following steps that 1, buttresses are constructed at railway line shoulders according to related railway operation line operation requirements and buttress arrangement positions; 2, an overhead system is constructed and installed in the railway operation window period, the overhead system comprises temporary steel beams, and end plates of the temporary steel beams are connected; the temporary steel beam penetrates through the supporting cross beam; 3, prefabricating the frame bridge, and arranging a sliding structure on the top of the frame bridge; 4, frame bridge jacking operation is carried out; during the overhead period, the train passes at a low speed and stops working; 5, when the frame bridge is jacked to the supporting pile positions, supporting system conversion is conducted, the front-end supporting piers are dismantled, and jacking continues; and 6, the frame bridge is jacked to a preset position, a ballast bed is filled, and the overhead system is dismantled. Through the structure that the underpass structure is pushed to slide and supported in a sliding mode, maximum expansion of the size of the underpass railway structure is achieved, and technical support in the field is provided for development of the economic society.
本发明公开了一种大跨框架桥下穿铁路顶推施工方法，包括以下步骤：步骤1、在铁路线路路肩处根据相关铁路运营线作业要求和支墩布置位置施工支墩；步骤2、在铁路运营窗口期施工安装架空体系，架空体系包括钢便梁，各钢便梁的端头板连接；钢便梁下穿支撑横梁；步骤3、预制框架桥，在框架桥顶设置滑动结构；步骤4、框架桥顶进作业；架空期间列车低速通过，通过时停止作业；步骤5、框架桥顶进至支撑桩位时，进行支撑体系转换，拆除前端支撑墩，继续顶进；步骤6、框架桥顶进到达预定位置，填充道床，拆除架空体系。本发明通过下穿结构既被顶推滑动又滑动支撑的结构，实现下穿铁路结构尺寸的最大限度扩容，为经济社会的发展提高该领域的技术支持。
