Bridge expansion joint edge drainage asphalt pavement internal seepage rapid drainage device
The invention belongs to the technical field of pavement drainage, and particularly relates to a rapid drainage device for internal seepage of a drainage asphalt pavement at the edge of a bridge expansion joint. Comprising the steps that a transverse water collecting pipe is arranged in drainage asphalt on the side edge of the expansion joint to form a drainage cavity; the cross section of the transverse water collecting pipe is a trapezoidal steel pipe, and the inclined side of the trapezoid is a water-passing steel plate which is provided with a water-passing hole facing the driving direction; the device further comprises a water collecting hopper and a water outlet bent pipe. A small opening at the bottom of the water collecting hopper is in sealed butt joint with a water outlet elbow pipe; the large opening of the water collecting hopper is butted and communicated with the bottom surface of the end part of the transverse water collecting pipe; the water outlet elbow is connected with a main drainage pipe of the bridge body through a siphon drainage hose; seepage water in the drainage asphalt is rapidly drained to the main drainage pipe in a siphon mode. The drainage device is simple in structure, high in drainage efficiency and stable, accumulated water near the expansion joint can be rapidly and timely drained, and the driving comfort and safety are improved.
本发明属于路面排水技术领域，具体为一种桥梁伸缩缝边缘排水性沥青路面内部渗流速排装置。包括：在伸缩缝侧边排水性沥青中设置的横向收水管，形成排水空腔；横向收水管横截面为梯形的钢管,梯形斜边一面为过水钢板,面对行车方向，上设有过水孔；还包括集水斗和出水弯管；集水斗顶部大开口设置进水格栅板,底部小开口密封对接出水弯管；集水斗开口大和横向收水管端部底面对接并连通；出水弯管通过虹吸排水软管和桥体的主排水管连接；通过虹吸方式快速排出排水性沥青中的渗流水到主排水管。本发明结构简单，排水效率高且稳定，可以快速、及时排除伸缩缝附近的积水，提高了行车的舒适性和安全性。
