Through arch bridge structure suitable for overpass expressway and construction method of through arch bridge structure
The through arch bridge structure comprises a steel box main longitudinal beam and a main arch structure, the top face of the steel box main longitudinal beam is connected with the main arch structure, the steel box main longitudinal beam adopts a box-shaped section, a transverse partition plate is arranged in the box, and the transverse partition plate and the transverse partition plate are connected through a steel transverse beam; shear nails are arranged on the top faces of the steel cross beams, prefabricated concrete bridge deck slabs are placed on the top faces of the steel cross beams, and wet joints between the prefabricated concrete bridge deck slabs are poured, so that bonding of cast-in-place concrete wet joints and the shear nails is achieved, connection between longitudinal sections of the prefabricated concrete bridge deck slabs is completed, and connection between the prefabricated concrete bridge deck slabs and the steel cross beams is achieved. According to the prefabricated concrete bridge deck, the prefabricated concrete bridge deck is not combined with the steel box main longitudinal beam and only forms a combined section with the steel cross beam, it is guaranteed that the suspender has enough anchoring space, the stress influence of shrinkage and creep of the concrete bridge deck on the steel box main longitudinal beam structure is reduced, the stress of the concrete bridge deck is simplified into a longitudinal one-way plate, and the stress is simpler.
本发明公开了一种适用于上跨高速公路的下承式拱桥结构及其施工方法，包括钢箱主纵梁和主拱结构，钢箱主纵梁顶面连接有主拱结构，钢箱主纵梁采用箱形截面，箱内设置有横隔板，横向之间通过钢横梁连接；钢横梁顶面设置有剪力钉以及放置有预制混凝土桥面板，通过浇筑预制混凝土桥面板之间的湿接缝，用于实现现浇混凝土湿接缝与剪力钉的粘结以及完成预制混凝土桥面板纵向节段之间的连接，实现预制混凝土桥面板与钢横梁的连接。本发明预制混凝土桥面板采用不与钢箱主纵梁结合，仅与钢横梁形成联合截面，不仅保证吊杆具有足够的锚固空间，也减小混凝土桥面板收缩徐变对钢箱主纵梁结构的受力影响，混凝土桥面板受力简化为纵向单向板，其受力更为简单。
