Mountainous area large-span steel-concrete composite beam on-site assembly and bridge erecting machine erecting construction method
The invention discloses a mountainous area large-span steel-concrete composite beam on-site assembly and bridge erecting machine erecting construction method. The method comprises the steps of: prefabricating steel box girders; assembling the prefabricated steel box girders in a segmented mode; positioning and mounting a steel box girder top precast slab; and erecting the prefabricated steel box girders. The steel-concrete composite beam on-site assembly and erecting construction technology can be applied to expressway steel-concrete beam construction under various conditions; steel-concrete beams are produced in a segmented and industrialized mode and transported to a construction site to be assembled into prefabricated slabs. The construction progress is accelerated, the construction period is shortened, the respective technical advantages of a steel structure and a concrete structure are brought into full play, meanwhile, the self-load of the structure can be reduced, the section size is reduced, the structure fatigue resistance and anti-seismic properties are enhanced, and the structure stability is improved.
本发明公开了一种山区大跨径钢混组合梁现场拼装及架桥机架设施工方法，其中包括：钢箱梁预制；对所述预制的钢箱梁进行分段拼装；定位安装钢箱梁顶预制板；对所述的预制钢箱梁进行架设。该钢混组合梁现场拼装及架设施工技术可以运用于多种情况下的高速公路钢混梁施工中，通过钢混梁分段工厂化生产并运输至施工现场进行预制板拼装，加快了施工进度、缩短施工周期，充分发挥钢结构及混凝土结构各自技术优点的同时，能够减轻结构自身荷载，减小截面尺寸、增强结构抗疲劳能力及抗震性能、提高结构稳定性等优点。
