Small-radius large-span bridge via hole construction method
The invention provides a small-radius large-span bridge via hole construction method, which belongs to the technical field of bridge construction. According to the method, a crane is in place on the ground; the crane lifts one end of a box girder, the other end of the box girder is arranged on a girder transporting vehicle, and the crane and the girder transporting vehicle are matched to move thebox girder; and the box girder is moved to the position between two bridge piers waiting for hole passing, and girder falling is conducted. According to the small-radius large-span bridge via hole construction method provided by the embodiment of the invention, the box girder is hoisted on the ground by the crane, the box girder is transported by the girder transporting vehicle, and the crane is used for hoisting, so that the flexibility is high, and construction equipment or the box girder is prevented from conflicting with other structures during construction; the assembled prefabricated erection construction process is adopted for the box girder of the small-radius large-span bridge, the construction period can be shortened, the work efficiency is improved, the construction progress isaccelerated, the subsequent construction progress is not influenced, and the assembly degree of engineering construction is improved.
本发明提供一种小半径大跨度桥梁过孔施工方法，属于桥梁施工技术领域，包括起重机在地面上就位；所述起重机吊起箱梁的一端，所述箱梁的另一端设在运梁车上，所述起重机和所述运梁车配合移动所述箱梁；将所述箱梁移动到待过孔的两个桥墩之间，落梁。本发明实施例提供的小半径大跨度桥梁过孔施工方法，采用起重机在地面上对箱梁进行吊装，配合运梁车运送箱梁，起重机吊装，灵活性高，避免施工时，施工设备或箱梁与其他结构冲突，对于小半径大跨度桥梁的箱梁采用装配式预制架设施工工艺，能够节约工期，提高工效，加快了施工进度，不影响后续施工进度，提高了工程建设的装配化程度。
