Bridge floor drainage system of bridge crossing sensitive area
The invention discloses a bridge floor drainage system of a bridge crossing a sensitive area. A bridge crosses an urban sensitive area, bridge floor runoff is not allowed to be discharged, and the bridge floor runoff needs to be effectively collected and discharged. A longitudinal main drainage channel is arranged close to a non-motorized lane in a space below a bridge sidewalk plate, and meanwhile, a non-motorized lane side drainage ditch, an auxiliary lane anti-collision wall side longitudinal drainage ditch and a motorized lane anti-collision wall side longitudinal drainage ditch are arranged along a bridge longitudinal slope; a transverse groove is formed in the upstream of each expansion joint, and bridge floor runoff is drained to a longitudinal main drainage channel through a transverse slope; the main drainage channel is communicated with a bridge tail end water collecting tank outside the sensitive area, and the bridge tail end water collecting tank is communicated with a ground rainwater pipeline system through a tank bottom downpipe. The bridge deck runoff collecting effect is improved, accumulated water on the bridge deck is effectively reduced, and the drainage problem of a bridge crossing a sensitive area is solved.
本发明公开了一种跨越敏感区域桥梁的桥面排水系统。桥梁跨越城市敏感区域，不允许将桥面径流散排，需对对桥面径流进行有效收集及排放。本发明桥梁人行道板下空间的靠近非机动道设置纵向主排水通道，同时沿桥梁纵坡设置非机动车道边排水沟、辅助车道防撞墙边纵向排水沟、机动车道防撞墙边纵向排水沟；每道伸缩缝上游设置横截沟，利用横坡将桥面径流排至纵向主排水通道；主排水通道与敏感区域以外的桥梁末端集水槽连通，所述桥梁末端集水槽通过槽底落水管与地面雨水管道系统连通。本发明改善桥面径流收集效果，有效消减桥面积水，解决了跨越敏感区域桥梁的排水问题。
