Construction method for pushing steel box girder to overpass existing expressway
The invention discloses a construction method for pushing a steel box girder to cross an existing expressway, and belongs to the technical field of bridge construction. The construction method of the steel box girder pushing and overcrossing the existing expressway comprises the steps of steel box girder box body manufacturing, overall steel box girder welding and assembling, temporary pier column construction, guide girder installation, steel box girder horizontal side pushing, girder falling and the like. The construction method for pushing the steel box girder to cross the existing expressway is simple in process, low in cost, high in efficiency, safe and reliable, and the problem that the steel box girder on the expressway is difficult to construct can be effectively solved; the construction efficiency can be improved and the construction cost can be greatly reduced no matter whether the construction method that the steel box girder is used on a main bridge or an E-ramp bridge to push the existing expressway is adopted for construction.
本发明公开了一种钢箱梁顶推上跨既有高速公路的施工方法,属于桥梁施工技术领域;该钢箱梁顶推上跨既有高速公路的施工方法包括钢箱梁箱体制作、整体钢箱梁焊接组装、临时墩柱建设、导梁安装、钢箱梁水平侧推、落梁等步骤;该钢箱梁顶推上跨既有高速公路的施工方法工艺简单,成本低,效率高,安全可靠,可以有效解决公路上钢箱梁施工难的问题;无论是在主线桥或是在E匝道桥上采用该钢箱梁顶推上跨既有高速公路的施工方法进行施工,均能够提高施工效率,较大幅度的降低施工成本。
