The invention provides an automatic bridge reinforcing structure after bridge overload. The structure comprises a bridge, piers, pier bases and steel cables. A reinforcing pipe is welded at the bottomof the bridge; reinforcing ribs are embedded in the piers; the other end of an inhaul cable penetrates through the piers and is fixedly connected with the steel cables; a shear knife is welded at thebottom of the piers; a balance weight cavity is formed in the middle of the inner portion of each pier base; and a balancing weight is supported in the balancing weight cavity, a shearing cavity is formed in the side surface of the balancing weight cavity, a supporting rod is fixedly connected to the inner side surface of the shearing cavity, an inserting ball is fixedly connected to the other end of the supporting rod, the inserting ball is connected with the side surface of the balancing weight in an inserted mode, and an elastic layer is arranged at a joint of each pier and each pier base.Due to matched arrangement of the shear knife and the supporting rods, when the bridge is in an overload state, the balancing weight can pull the steel cables to be straighter, the bridge is furtherreinforced, the steel cables can drive the reinforcing ribs to sink instantly through the inhaul cables, connection between the reinforcing ribs is reinforced, a bearing capacity of the bridge piers is improved, and the bridge piers are prevented from being broken.
本发明提供了一种桥梁过载后的桥梁自动加固结构，包括桥梁、桥墩、桥墩座、钢索，桥梁的底部焊接有加固管，桥墩的内部嵌有加强筋，拉索的另一端贯穿桥墩并与钢索固定连接，桥墩的底部焊接有剪切刀，桥墩座内部的中间开设有配重空腔，配重空腔内部支撑有配重块，配置空腔的侧面开设有剪切空腔，剪切空腔的内侧面固定连接有支撑杆，支撑杆的另一端固定连接有插接球，插接球与配重块的侧面插接，桥墩与桥墩座的连接处设置有弹性层。本发明因剪切刀与支撑杆的配设置，当桥梁处于超载状态时，配重块会将钢索拉的更加笔直，进一步加固桥梁，并且钢索会通过拉索带动加强筋瞬间往下沉，加强筋之间的连接加固，提高桥墩的承载能力，防止桥墩出现断裂。
