Permeable asphalt pavement drainage system
The invention discloses a permeable asphalt pavement drainage system, and relates to the field of pavement drainage. The permeable asphalt pavement efficient drainage structure comprises a surface layer, a base layer, a cushion layer and a drainage device; the surface layer is divided into an upper surface layer and a lower surface layer, a sealing layer is laid between the lower surface layer andthe base layer, and the cushion layer serves as a waterproof layer. The drainage device is located on the side of the surface layer and an inlet is used for receiving rainwater of the road surface layer. The drainage device comprises a drainage channel and a drainage pipeline, the drainage pipeline divides the drainage channel into a first drainage channel and a second drainage channel, and a water level controller is installed at an inlet of the drainage pipeline. Filter screen filter layers are arranged at inlets and outlets of the two drainage channels. The permeable asphalt pavement drainage system has the characteristics of high water filtering, storing and draining efficiency and prevention of forming accumulated water on a pavement. Meanwhile, the permeable asphalt pavement can weaken the dynamic water pressure and the vacuum negative pressure suction effect generated by wheels on the pavement, and rainwater in the pavement can be transferred into the drainage pipe through a gap.
本发明是一种透水沥青路面排水系统发明，涉及路面排水领域。透水沥青路面高效排水结构包括面层、基层、垫层以及排水装置，面层分为上下面层，下面层与基层间铺设一层封层，垫层作为防水层使用。排水装置位于面层侧边，入口用于承接路面层雨水。排水装置包括：排水渠道和排水管道，排水管道将排水渠道分隔为第一、二排水渠道，且排水管道入口处装有水位控制器。两排水渠道入口和出口处设置有滤网过滤层。透水沥青路面排水系统具有过滤、存储水以及排水效率高、不易在路面形成积水的特点。同时透水沥青路面可减弱车轮对路面产生的动水压力与真空负压抽吸作用，路面内部的雨水会经空隙转移到排水管中。
