The invention relates to a flood discharge bridge which comprises bridge piers, longitudinal connecting beams are connected between the adjacent bridge piers which are longitudinally arranged, and tiebeams are connected between the adjacent longitudinal connecting beams; transverse connecting beams are connected between the adjacent bridge piers which are transversely arranged, concrete capping beams are connected to the tops of the adjacent bridge piers which are transversely arranged, and the longitudinal arrangement distance of the adjacent bridge piers is greater than the transverse arrangement distance of the adjacent bridge piers. and the lower portions of the piers stretch into a concrete pile casing, and a gap between each pier and the concrete pile casing is filled with a sandy gravel mixture to form flexible connection. The overall rigidity of the piers is enhanced through the longitudinal connecting beams, the transverse connecting beams and the tie beams, overturning caused by flood impact is effectively prevented through the arrangement of the concrete pile casing, concrete slabs are arranged on a riverbed silt layer to prevent riverbed silt from overflowing to hinderflood from flowing through a bridge arch when the flood comes, and rubber pads can buffer the impact force of the flood. Air spraying holes reduce the water flow speed and reduce the impact force offlood on the pier.
本发明涉及一种泄洪桥梁，包括：桥墩，纵向布置的相邻桥墩之间连接有纵向连接梁，相邻的纵向连接梁之间连接有拉结梁；横向布置的相邻桥墩之间连接有横向连接梁，相邻的横向布置的桥墩顶部连接有混凝土压顶梁，且相邻桥墩纵向布置距离大于相邻桥墩横向布置的距离；以及混凝土护筒，桥墩下部伸入混凝土护筒内，且桥墩与混凝土护筒之间空隙填塞有砂卵石混合料形成柔性连接。本发明通过纵向连接梁、横向连接梁和拉结梁增强桥墩整体刚度，通过混凝土护筒设置，有效防止洪水冲击出现倾覆，混凝土板在河床淤泥层上防止河床淤泥在洪水来时泛滥阻碍洪水流过桥拱，橡胶垫可以缓冲洪水的冲击力。喷气孔缓冲水流速度，减少洪水对桥墩的冲击力。
