Construction method for erecting double-layer prefabricated box girder bridge
The invention discloses a construction method for erecting a double-layer prefabricated box girder bridge, which comprises the following steps of: arranging a prefabricated girder field on one side of the double-layer prefabricated box girder bridge, and prefabricating prefabricated box girders required by each bridge span in the prefabricated girder field; two rows of parallel gantry crane rails are arranged in the bridge erecting direction, and two gantry cranes are arranged on the gantry crane rails at intervals. The distance between the two rows of gantry crane rails is not smaller than the sum of the width of the precast beam yard and the width of the double-layer precast box girder bridge, so that the gantry crane stretches across the precast beam yard and the double-layer precast box girder bridge; and the two gantry cranes directly hoist and erect the prefabricated box girder from the prefabricated girder yard to a capping beam on the lower layer or the upper layer of the double-layer prefabricated box girder bridge. The prefabricated beam field is arranged close to the double-layer prefabricated box girder bridge, prefabricated box girders do not need to be transported, the prefabricated box girders are directly hoisted and erected to the upper-layer or lower-layer bent cap through the two gantry cranes, the construction time can be effectively saved, and construction site management is optimized.
本发明公开了一种用于双层预制箱梁桥架设的施工方法，包括：在所述双层预制箱梁桥的一侧设置一个预制梁场，在所述预制梁场预制各桥跨所需的预制箱梁；沿桥梁架设方向设置两列平行的门机轨道，所述门机轨道上间隔设置有两台龙门吊；两列所述门机轨道之间的间距不小于所述预制梁场的宽度和所述双层预制箱梁桥的宽度之和，以使所述龙门吊横跨在所述预制梁场和所述双层预制箱梁桥上方；由两台所述龙门吊直接从所述预制梁场内将所述预制箱梁吊装架设至所述双层预制箱梁桥下层或上层的盖梁上。本发明预制梁场靠近双层预制箱梁桥设置，不需要进行预制箱梁运输，由两台龙门吊直接吊装架设至上层或下层的盖梁上，可有效节约施工时间，优化施工现场管理。
