Plate arch bridge reinforcing structure and reinforcing method
The invention relates to a reinforcing structure and a reinforcing method for a plate arch bridge, an arch ring filler and an arch seat filler are disclosed, the arch ring filler and the arch seat filler are connected through an arch foot connecting device, and supporting rods are arranged between the arch ring filler and the arch seat filler in a crossed mode; a plurality of anchor rods connected with a plate arch bridge arch ring are inserted into the arch ring filler, a plurality of embedded steel bars used for being embedded into plate arch bridge concrete are connected to the skewback filler, and the technical problem that an existing plate arch bridge is insufficient in bearing capacity due to the fact that loads are increased is solved. According to the reinforcing method for the plate arch bridge, the corrugated steel serves as a formwork for pouring concrete in the construction process, the time for erecting the formwork can be greatly saved, meanwhile, due to the out-of-plane supporting effect of the corrugated steel plate, the ductility of the reinforced structure is obviously improved, the integrity of the structure can be effectively improved, and therefore the bearing capacity of the structure is improved, and the service life of the plate arch bridge is prolonged. And external stress is resisted by increasing constraint, and the technical problem that an existing section increasing method is complex in construction is solved.
本发明为板拱桥加固结构及加固方法，公开的拱圈填料和拱座填料，拱圈填料和拱座填料通过拱脚连接装置连接，拱圈填料和拱座填料之间交叉设有支撑杆；拱圈填料上插有若干连接板拱桥拱圈的锚杆，拱座填料上连接有若干用于植入板拱桥混凝土的植入钢筋，解决了现有板拱桥因负荷加大导致承载力不足的技术问题。本发明板拱桥加固方法通过在施工过程中将波纹钢作为浇筑混凝土的模板，可以大幅节约搭设模板的时间，同时由于波纹钢板的面外支撑作用，加固后结构的延性也将得到明显的提升，可以有效改善结构的整体性，从而提高结构承载力，还通过增加约束来抵抗外应力，解决了现有增大截面法施工复杂的技术问题。
