Assembly type reinforcing structure and method suitable for simply supported girder bridge of mountainous highway
The invention discloses an assembly type reinforcing structure and method suitable for a simply supported girder bridge of a mountainous highway. The assembly type reinforcing structure comprises a supporting foundation, a supporting bent frame, a leveling steel box and a support. The lower end of the supporting bent frame is fixed to the supporting foundation, the leveling steel box is supportedby the upper end of the supporting bent frame, and the support is located on the leveling steel box. By means of the reinforcing structure and method, the bridge integrity defects that the upper portion and the lower portion of a simply-supported girder bridge in a mountainous area are relatively staggered, supports are displaced and disengaged, a girder body is low in tightness, a bridge deck arches, and piles, tie beams and bent caps crack in a large range can be overcome. The supporting foundation, the supporting bent frame, the leveling steel box and the support are arranged beside the pier stud, so that the old bridge has high stability, bearing capacity and reinforcing function, the overall performance of the old bridge can be improved, the service life of the old bridge is greatly prolonged, and the assembly type reinforcing structure is suitable for popularization.
本发明公开了一种适用于山区公路简支梁桥装配式加固结构及方法；装配式加固结构包括：支撑基础、支撑排架、调平钢箱和支座；支撑排架的下端固定在支撑基础上，支撑排架的上端支撑调平钢箱，支座位于调平钢箱上。本加固结构及方法能够解决山区简支梁桥出现上下部相对错位，支座移位、脱空，梁体低紧，桥面起拱，桩柱及系梁、盖梁大范围开裂等桥梁整体性病害。通过在墩柱旁设置支撑基础、支撑排架、调平钢箱和支座，使旧桥具有较强的稳定性、承载能力与加固功能，能够提高旧桥的整体性能，大大延长旧桥使用寿命，适合推广。
