Hoop steel pipe combined supporting system in large-span cast-in-place bridge and construction method of hoop steel pipe combined supporting system
The invention discloses a hoop steel pipe combined supporting system in a large-span cast-in-place bridge and a construction method of the hoop steel pipe combined supporting system. The hoop steel pipe combined supporting system comprises a plurality of bridge piers jointly supporting a box girder formwork and steel structure supports laid between every two adjacent bridge piers at intervals, and a bearing beam is transversely laid on the top of each bridge pier and the top of each steel structure support; the bearing beams are arranged at intervals in the extending direction of the bridge and jointly support the bailey beam, and the top of the bailey beam supports the box beam formwork; a pile foundation arranged in a soil layer is arranged at the bottom of each steel structure bracket; the upper portion of each pier is fixedly sleeved with a hoop assembly. A beam falling sand box is arranged on the hoop assembly, and a bailey beam is supported at the top of the beam falling sand box through a bearing beam; the bailey beams and the box beam formwork are supported through a plurality of distribution cross beams. And each distribution cross beam can be adjusted in a lifting manner. The technical problem that a large-span cast-in-place bridge is difficult to arrange a cast-in-place full framing for construction under the conditions of large soft foundation surface and complex topographic and geological conditions can be solved.
本发明公开了一种大跨度现浇桥中抱箍钢管组合支撑体系及其施工方法，包括共同支撑箱梁模板的若干桥墩以及间隔铺设在每两座相邻的桥墩之间的钢结构支架，每一桥墩与每一钢结构支架顶部横向铺设有一承重梁，使得若干承重梁沿桥梁的延伸方向间隔设置并共同支撑贝雷梁，贝雷梁的顶部支撑着箱梁模板；每一钢结构支架底部设有设置于土层中的桩基础；每一座桥墩的上部均固定套装有抱箍组件；抱箍组件上设有落梁砂箱，在落梁砂箱顶部通过承重梁支撑贝雷梁；贝雷梁与箱梁模板之间通过若干分配横梁支撑；每一分配横梁均可升降调节。本发明可以解决大跨度现浇桥在软弱基础面大、地形地质条件复杂很难设置现浇满堂支架施工的技术难题。
