Bridge system capable of crossing operation road at small angle without interrupting traffic construction
The invention belongs to the technical field of bridges, and particularly relates to a bridge system capable of crossing an operation road at a small angle without interrupting traffic construction, which comprises an upper structure and a lower structure for supporting the upper structure, wherein the lower structure comprises a plurality of gate-type frame piers which conform to the crossing direction of the bridge and stretch across the existing operation road, and through multi-point supporting of the gate-type frame piers, the part, stretching across the existing operation road, of the bridge forms a multi-span and medium-span bridge structure; according to the bridge, the span of the upper structure can be reduced through multi-point supporting of the portal frame piers, so that a multi-span bridge structure is obtained, and medium-economic-span bridge spanning is achieved. Due to the fact that multi-point supporting of the gate-type frame piers can guarantee uniform stress of the bridge structure, a large-span bridge structure is avoided, the construction difficulty is greatly reduced, and the construction cost of the bridge is correspondingly reduced.
本发明属于桥梁技术领域，特别涉及一种不中断交通施工小角度跨越运营道路的桥梁体系，包括上部结构以及支撑所述上部结构的下部结构；其中，所述下部结构包括多个顺应桥梁跨越方向且横跨既有运营道路的门式框架墩，通过多个所述门式框架墩的多点支撑，桥梁跨越既有运营道路的部分形成多跨中等跨径的桥梁结构；本发明的桥梁通过门式框架墩的多点支撑可以减小上部结构的跨径以得到多跨桥梁结构，实现中等经济跨径桥梁跨越。由于门式框架墩的多点支撑能够保证桥梁结构的受力均匀，避免了大跨径桥梁结构，其施工难度大大降低，桥梁的建设成本相应减少。
