Description
Technical Field
The utility model relates to a road and drainage technical field especially relate to a permeable pavement flat curb drainage system.
Background
The sponge city is a sustainable city construction mode from the aspect of city rainfall flood management, wherein the hard road surfaces of urban roads, squares and the like are paved by water permeation, which is an important sponge city technical means. At present, permeable asphalt is generally adopted for permeable pavement, and permeable concrete is easier to crack a pavement than common cement concrete due to the problem of drying shrinkage, and is rarely adopted.
The permeable pavement has many advantages, reduces the rainwater runoff of the road, and the rainwater directly permeates into the road surface layer when raining in middle and small areas, so that the road surface can not form a water film, and the running safety of the vehicle is improved. However, if rainwater continues to infiltrate into the road base layer and the road base layer, adverse effects can be caused on the overall strength and safety of the road, so that the existing permeable pavement of the motor vehicle lane basically only adopts a permeable structure on the surface layer, the base layer and the road base layer are impermeable, and an impermeable seal layer is arranged between the layers to prevent rainwater from infiltrating. Rainwater that permeates the inside of the permeable facing typically has several types of drainage to flow through: (1) on a road with an organic non-isolation zone, vertical kerbs at the edge of a motor vehicle lane are provided with openings at intervals, and seepage rainwater flows to the vertical kerbs along a cross slope of the road and is blocked, then flows to the openings of the vertical kerbs along a longitudinal slope of the road, flows into the organic non-isolation zone and is discharged into a rainwater pipeline system through an overflow well in the isolation zone; (2) under the condition that a sidewalk is arranged outside the motor vehicle lane or the motor vehicle non-isolation belt does not allow rainwater to flow in, a drainage ditch is generally arranged below a vertical curb on the outer side of the motor vehicle lane, openings are arranged at intervals on the vertical curb, and rainwater flows through the openings of the curb and falls into the drainage ditch to be drained out of the road.
However, the above situation is the situation that no flat kerbs are arranged on the edge of the motor vehicle lane, and in many domestic cities, the flat kerbs are arranged on the edge of the motor vehicle lane in order to improve the linear induction effect of vehicle driving, remind the driver of paying attention to the lateral safety distance when the vehicle is driven, and improve the overall visual effect of the road. Rainwater permeating into the permeable surface layer is blocked by the flat kerbs and cannot be discharged through the way. If the prefabricated pervious concrete flat kerb is adopted, the problem of drying shrinkage is difficult to solve, so that the flat kerb is separated from the road surface and the vertical kerb to form obvious longitudinal cracks and a height difference, and the pervious concrete flat kerb is not basically adopted in the market at present.
