Method for erecting double-layer box girder bridge
The invention relates to an erecting method of a double-layer box girder bridge. The erecting method comprises the steps that an upper box girder, a lower box girder and a lower-layer pier structure are prefabricated and formed in a prefabrication site; sequentially transporting the lower-layer pier structure and the upper box girder to a to-be-erected site by adopting a transport ship; the lower-layer bridge pier structure is erected at a preset position through the above-water hoisting equipment, and the lower box girder is erected on the lower-layer bridge pier structure through the above-water hoisting equipment, so that a lower-layer box girder bridge is formed; upper-layer pier bodies are cast on site at the two ends of the lower-layer pier structure, and upper cross beams are cast on the upper portions of the upper-layer pier bodies; after the upper box girder is transported to a to-be-erected site by a transport ship, the upper box girder is erected on the upper cross beam by an overwater hoisting device to form an upper-layer box girder bridge, so that the erection of the whole double-layer box girder bridge can be completed; and the upper box girder, the lower box girder and the lower-layer bridge pier structure are formed by adopting a prefabrication method and then are hoisted through overwater hoisting equipment, so that the construction period can be shortened, and the construction efficiency is improved.
本申请涉及一种双层箱梁桥梁的架设方法，包括：在预制场地预制成型上箱梁、下箱梁和下层桥墩结构；采用运输船依次将下层桥墩结构和上箱梁运输至待架设场地；采用水上吊运设备将下层桥墩结构架设在预设位置，采用水上吊运设备将下箱梁架设在下层桥墩结构上，以形成下层箱梁桥梁；在下层桥墩结构的两端现场浇筑上层墩身，并在上层墩身的上方现场浇筑形成上横梁；采用运输船将上箱梁运输至待架设场地后，采用水上吊运设备将上箱梁架设在上横梁上，以形成上层箱梁桥梁，从而可以完成整个双层箱梁桥梁的架设，且上箱梁、下箱梁和下层桥墩结构采用预制的方法成型后再通过水上吊运设备进行吊装，可以缩短工期，提高施工效率。
