Concentrated drainage structure of fusiform bridge
The invention discloses a concentrated drainage structure of a fusiform bridge. A centralized drainage structure of the bridge generally adopts a steel or PVC circular pipe structure and is externally hung on the outer side of a main beam, so that the pneumatic shape mutation of the section of the bridge is easily caused, and the large-amplitude vortex-induced vibration of the main beam is excited. The lower end of a vertical drainage pipe communicates with a fusiform longitudinal drainage pipe by a pipe joint, and the fusiform longitudinal drainage pipe is connected with a circular pipe leading-out bridge at the beam end by a conversion joint; the cross section of one end of the adapter is the same as the cross section of the fusiform longitudinal drainage pipe, and the cross section of the other end of the adapter is the same as the cross section of the connecting round pipe. The fusiform drainage pipe is of a fusiform streamline structure, vortex-induced amplitude is effectively restrained on the basis that the drainage flow requirement of a bridge is met, the aerodynamic performance is good, and the use performance and safety of the whole bridge structure are guaranteed.
本发明公开了一种梭形桥梁集中排水结构。桥梁集中排水结构一般均采用钢材或者PVC圆管结构，外挂于主梁外侧，易引起桥梁截面气动外形突变，激发主梁大幅涡激振动。本发明中竖向排水管下端通过管接头与梭形纵向排水管连通，梭形纵向排水管在梁端部通过转换接头连接圆管引出桥梁；梭形纵向排水管为梭形流线形结构，所述转换接头一端横截面与梭形纵向排水管相同，另一端横截面与连接圆管相同。本发明梭形排水管采用梭形流线形结构，在满足桥梁排水流量需求的基础上，有效抑制涡激振幅，且气动性能良好，保证了整个桥梁结构的使用性能及安全性。
