Single-arch-rib framing swivel construction steel box arch bridge and construction method thereof
The invention belongs to the technical field of arch bridge construction, and relates to a single-arch-rib framing swivel construction steel box arch bridge and a construction method thereof. The archbridge comprises a lower rotating disc located on a foundation, a horizontal rotating system fixedly installed on the lower rotating disc, an upper rotating disc installed on the horizontal rotatingsystem in a rotating mode, two sets of bridge deck longitudinal beams fixed to the upper rotating disc, and a vertical rotating hinge installed on the inner side of the upper rotating disc and used for fixing an arch rib to be constructed. The upper rotating disc, the lower rotating disc and arch ribs are arranged in a left-right framing manner, transverse supports and inter-rib cross beams are arranged between the left framing arch rib and the right framing arch rib, a suspender cross beam is fixedly mounted between the bridge deck longitudinal beams, suspenders are arranged at equal intervals along the longitudinal direction of each arch rib, the upper ends of the suspenders are anchored to the arch ribs, the lower ends of the suspenders are anchored to the suspender cross beams, a plurality of secondary cross beams are arranged between the suspender cross beams, and the suspenders, the suspender cross beams, the secondary cross beams and the bridge deck longitudinal beams are connected to form a lattice system in order to construct a bridge deck framework. The construction method guarantees the construction quality of the arch bridge, reduces safety risks and construction cost,and achieves convenient construction.
本发明属于拱桥施工技术领域，涉及一种单拱肋分幅转体施工钢箱拱桥及其施工方法，包括坐落在地基上的下转盘、固定安装在下转盘上的平转系统、转动安装在平转系统上的上转盘、固定在上转盘上的两组桥面纵梁以及安装在上转盘内侧且用于固定待施工拱肋的竖转铰，上转盘、下转盘以及拱肋采用左右分幅设置，左右分幅拱肋之间设置横撑和肋间横梁，桥面纵梁之间固定安装有吊杆横梁，沿每根拱肋纵向等间距设置吊杆，吊杆上端锚固于拱肋，下端锚固于吊杆横梁，吊杆横梁之间设置若干次横梁，吊杆、吊杆横梁、次横梁、桥面纵梁连接形成格构体系，组成桥面骨架，该施工方法保障了拱桥的施工质量，降低了安全风险，且施工方便，降低了施工成本。
