Arch bridge reinforcing structure without interrupting traffic and construction method thereof
The invention relates to an arch bridge reinforcing structure without interrupting traffic and a construction method thereof.The arch bridge reinforcing structure comprises a steel frame arch with hinged supports at the two ends, the hinged supports are arranged on corresponding retaining walls through vertical supporting pieces, the retaining walls are located on the front walls of corresponding existing bridge abutments, and the hinged supports are arranged on the front walls of the corresponding existing bridge abutments. The hinged supports abut against the front walls of the corresponding existing bridge abutments through the transverse supporting pieces, and the steel frame arches can abut against the existing arch rings through the vertical supporting pieces and the transverse supporting pieces. By the adoption of the structure, the bearing capacity of the arch feet is obviously improved, the structure is more suitable for the requirement for the high lifting amplitude, the reinforcing structure cannot damage the existing arch bridge, the influence on the mechanical performance of an existing arch bridge foundation and an arch ring is very small, the original bearing capacity of the existing bridge cannot be reduced during dismantling, the steel frame arch can be independently stressed, and the construction cost is reduced. When the reinforcing structure is constructed, disturbance to the existing arch bridge is small, traffic does not need to be interrupted when the arch bridge is reinforced, and the reinforcing structure is widely suitable for arch bridges of various material structures.
本发明涉及一种无需中断交通的拱桥加固结构及其施工方法，结构包含两端均为铰支座的钢架拱，所述铰支座通过竖向支撑件设于对应的挡墙上，所述挡墙位于对应的既有桥台的前墙处，所述铰支座通过横向支撑件抵接于对应的所述既有桥台的前墙，通过所述竖向支撑件和横向支撑件使所述钢架拱能够抵接所述既有拱圈。采用本结构对拱脚承载力提高明显，更适用于提升幅度较高的需求，加固结构不会对既有拱桥产生损伤，对既有拱桥基础及拱圈的力学性能影响非常小，在拆除时不会降低既有桥梁的原有承载能力，并且所述钢架拱能够单独受力，使得在施工该加固结构的时候对既有拱桥扰动小，因而加固拱桥时无需中断交通，本加固结构广泛适用于各种材料结构的拱桥。
