Construction method of large-span steel box girder
The invention discloses a construction method of a large-span steel box girder, and relates to the technical field of bridge construction. The bridge erecting machine solves the technical problem that in the prior art, a bridge erecting machine cannot install a large-span bridge. The construction method of the large-span steel box girder comprises the steps that a bridge girder erection machine is assembled on a bridge head or an erected precast beam, and debugging and acceptance inspection are carried out; a temporary pier is arranged between the first pier and the second pier; steel box girder main longitudinal beams are erected between the first pier and the temporary pier and between the second pier and the temporary pier respectively, and cross beams are erected between the steel box girder main longitudinal beams at the two ends of the first pier and the two ends of the second pier respectively; and removing the temporary piers after the bridge floor is completely paved. Therefore, the bridge girder erection machine can complete large-span hole passing through the temporary piers, compared with an original large-span steel box girder construction process, needed supports are reduced, the construction cost is saved, the construction mechanization level is improved by using the bridge girder erection machine, and the construction period is shortened.
本申请公开了一种大跨径钢箱梁的施工方法，涉及桥梁施工技术领域。本申请解决了现有技术中的架桥机无法安装大跨径的桥梁的技术问题。该大跨径钢箱梁的施工方法包括：架桥机在桥头或已经架好的预制梁上拼装，并调试和验收合格；第一桥墩和第二桥墩之间设置临时墩；第一桥墩和临时墩之间，以及第二桥墩和临时墩之间分别架设钢箱梁主纵梁，第一桥墩和第二桥墩的两端的钢箱梁主纵梁之间分别架设横梁；待桥面全部铺设完毕，拆除临时墩。因此，本申请实施例通过临时墩使得架桥机可以完成的大跨径过孔，相比原有大跨径钢箱梁建造工艺分段吊装和顶推施工减少了所需的支架，节约了施工成本，架桥机的使用提高了施工机械化水平，缩短了施工工期。
