Concrete-filled steel tube arch bridge and construction method thereof
The invention discloses a concrete-filled steel tube arch bridge and a construction method thereof. The construction method comprises the steps that the longitudinal frameworks are assembled, and the main arches, the wind braces and the temporary cross beams are installed to form a stiff framework system; a guide beam and a temporary buttress are installed at one end of the stiff skeleton system; pushing the stiff skeleton system; the stiff framework system is used as a support, and concrete of arch feet and end cross beams is poured; pouring concrete of the main arch and the straining beam; and installing the middle cross beam, the suspender and the carriageway plate. According to the embodiment of the invention, the stiff skeleton system not only can provide support and templates for the arch bridge girder during the construction period, but also can participate in structural stress during the operation period, so that the reinforcement quantity of the structure is reduced, the weight is light, the rigidity is high, and the requirement on pushing equipment is reduced. The concrete straining beam is low in manufacturing cost, good in durability and easy to maintain in the operation period. And temporary facilities such as supports do not need to be arranged, the engineering cost can be effectively reduced, the construction risk is reduced, the construction period is shortened, and economic benefits are brought to bridge construction.
本发明公开了一种钢管混凝土拱桥及其施工方法。施工方法包括：拼装纵向骨架，并安装主拱、风撑、临时横梁，形成劲性骨架体系；在劲性骨架体系的一端安装导梁和临时支墩；顶推劲性骨架体系；以劲性骨架体系为支撑，浇筑拱脚和端横梁的混凝土；浇筑主拱和系梁的混凝土；安装中横梁、吊杆和行车道板。本申请实施例通过劲性骨架体系不仅可以在施工期为拱桥主梁提供支撑和模板，还可在运营期参与结构受力，减少结构的配筋量，重量轻、刚度大，降低对顶推设备的要求。混凝土系梁造价低、耐久性好、运营期养护简单。不需要设置支架等临时设施，能有效降低工程造价，降低施工风险、缩短施工工期，为桥梁建设带来经济效益。
