Medium and small span steel-concrete composite structure arch bridge and construction method thereof
The invention discloses a small and medium span steel-concrete composite structure arch bridge and a construction method thereof, and relates to the technical field of civil engineering, a concrete skewback adopts a T-shaped structure, the horizontal force of the skewback can be effectively resisted, and meanwhile, due to the fact that the base area of the concrete skewback is large, the requirement for the bearing capacity of a foundation can be lowered; the upper structure of the arch bridge is made of profile steel components which are all manufactured in factories, only bolt connection is needed on site, the construction difficulty is greatly simplified, and the construction quality is improved. The bridge deck slab is paved by adopting a prefabricated part and on-site wet joint pouring mode, so that the construction progress is accelerated, and meanwhile, the construction quality can be ensured; the arch rib adopts a steel structure, so that concrete can be prevented from being pulled and cracked; compared with a small and medium span concrete arch bridge and a masonry arch bridge, operation diseases are obviously reduced, and the service life of the arch bridge is greatly prolonged. By the adoption of the building method, engineering requirements can be met, construction can be facilitated, and certain economic and social values are achieved.
本发明公开一种中小跨径钢混组合结构拱桥及其建造方法，涉及土木工程技术领域，本发明混凝土拱座采用T型结构，能够有效的抵抗拱座的水平力，同时由于混凝土拱座基底面积大，能够降低对地基承载力的要求；拱桥的上部结构采用型钢构件，均为工厂制作，现场仅需螺栓连接，大大的简化了施工难度，提高施工质量；桥面板采用预制构件+现场湿接缝浇筑的方式进行铺装，加快施工进度，同时可以保证施工质量；拱肋采用钢结构，可以避免混凝土的受拉开裂；相较于中小跨径混凝土拱桥和圬工拱桥，运营病害明显较少，极大的提高了拱桥的使用寿命。采用本发明的建造方法，既可以满足工程需要，又可方便施工，具有一定的经济、社会价值。
