The invention discloses a main beam mounting method of a river-crossing steel box girder bridge, belongs to the technical field of municipal bridge engineering construction, and provides a novel main beam mounting method of the river-crossing steel box girder bridge, which is convenient and fast to construct. The method specifically comprises the steps: before hoisting construction of the box girder section of the main girder, firstly, constructing and building a construction temporary bridge on each of two sides of the main body building area of the steel box girder bridge, arranging gantry rails on the construction temporary bridges along the trend of the construction temporary bridges, and supporting and erecting two gantry cranes on the gantry rails of the construction temporary bridges on the two sides; and then using the two gantry cranes for carrying out hoisting construction on all the box girder sections of the steel box girder bridge. According to the invention, the hoisting construction of each box girder section of the main girder can be carried out by directly adopting the hoisting method of the gantry crane, and then the hoisting construction of the main girder is carried out by fully utilizing the built construction temporary bridges on the two sides, so that the construction of the main girder is more convenient, and the hoisting construction cost can be effectively saved.
本发明公开了一种跨河钢箱梁桥的主梁安装方法，属于市政桥梁工程施工技术领域，提供一种新的、施工便捷的跨河钢箱梁桥的主梁安装方法，具体为在进行主梁的箱梁节段的吊装施工前，先在钢箱梁桥的主体搭设区域的两侧分别施工搭建一条施工便桥，并且在施工便桥上沿施工便桥的走向设置龙门轨道，在两侧的施工便桥的龙门轨道上支撑架设有两架龙门吊，然后利用两架龙门吊对钢箱梁桥的各箱梁节段进行吊装施工。本发明能直接采用龙门吊的抬吊方法进行主梁的各箱梁节段的吊装施工，进而充分利用已搭设的两侧施工便桥进行主梁的吊装施工，可使得主梁的施工更加方便，并可有效的节省吊装施工成本。
