Construction method of cast-in-place box girder crossing existing railway bridge
The invention discloses a construction method for a cast-in-place box girder to span an existing railway bridge, which comprises the following steps of: 1, modifying a through line, and changing the electric power layout of the bridge; 2, building a construction road; 3, pile foundation construction; fourthly, a bearing platform is constructed; 5, pier body construction; and sixthly, the box girder is erected and constructed. In the implementation process, an operating railway is not damaged, and the safety of the operating railway is guaranteed; the safety of the newly-built bridge is ensured, and safety accidents are avoided; the method is simple, feasible, easy to operate and low in cost.
本发明公开了一种现浇箱梁跨越既有铁路桥梁施工工法，包括如下步骤：步骤一：修改贯通线，改变桥梁的电力布局；步骤二：修筑施工便道；步骤三：桩基施工；步骤四：承台施工；步骤五：墩身施工；步骤六：箱梁架设施工。本发明在实施过程中对运营铁路不造成破坏，保证运营铁路的安全；确保了新建桥梁的安全，不发生安全事故；简单可行，易于操作，费用较低。
