TECHNICAL FIELD
[0001] The utility model relates to road construction technical field, more specifically, it relates to water storage pavement. BACKGROUND
[0002] With the acceleration of urbanization, water resource shortage, flood disaster and ecological environment deterioration of some cities in our country increasingly prominent, therefore how to control the rain flood of city effectively has become the key in the city construction planning.
[0003] The existing road structure generally adopts concrete or pitch and the like to lay, and the road structure is not water permeable, needs to drain through the drainage pipeline reserved in the road surface, but when encountering heavy rain weather or rainy season, the existing drainage pipeline drainage pressure is big, cannot effectively, quickly drain the accumulated water of the road surface, thereby leading to the phenomenon of waterlogging or road surface water, and there are safety hazards to vehicles and pedestrians.
[0004] Therefore, a new scheme needs to be proposed to solve this problem. UTILITY MODEL CONTENT
[0005] In view of the deficiencies of the prior art, the utility model aims at providing water storage pavement, which can quickly drain the accumulated water of the road surface.
[0006] The above technical purpose of the utility model is realized by the following technical scheme: the water storage pavement comprises a base layer, a water storage layer, a water permeation layer and a road surface layer are sequentially laid on the base layer, curb plates are fixedly connected on both sides of the base layer, the water storage layer, the water permeation layer and the road surface layer are laid between the two curb plates, and a plurality of pores exist in the road surface layer and the water permeation layer.
[0007] The utility model is further provided with: cavities are formed in the two curb plates, and a barrier net is fixedly connected to the top of the cavity.
[0008] The utility model is further provided with: a drainage pipeline is embedded in the water storage layer, a plurality of water inlets are formed in the two sides of the drainage pipeline, and the two ends of the drainage pipeline extend into the cavities and are in communication with each other.
[0009] The utility model is further provided with: the top surface of the road surface layer is arc-shaped.
[0010] The utility model is further provided with: a waterproof plate is laid between the water storage layer and the base layer, and a plurality of protrusions are arranged on the end of the waterproof plate close to the water storage layer.
[0011] The utility model is further provided with: the protrusions are in the shape of convex polygons, and the top ends of the protrusions are arc-shaped.
[0012] The present invention is further configured such that: a plurality of drainage outlets are provided on the top of the curbstone slab, and the drainage outlets are interconnected with the cavity.
[0013] In summary, this utility model has the following beneficial effects:
[0014] Water on the road surface can seep into the road interior through several pores in the pavement layer and the permeable layer. The water storage layer can store the water that has seeped into the road surface. Because there are several pores in the pavement layer and the permeable layer, when the weather outside is too hot, the water stored in the water storage layer can evaporate through the pores, thereby reducing the temperature of the road structure and playing a role in regulating the road surface temperature. It can also increase the humidity of the surrounding air. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] Water-retaining road surfaces, such as Figure 1 As shown, the road includes a base layer 1, on which a water-retaining layer 2, a permeable layer 3, and a pavement layer 4 are laid in sequence. The pavement layer 4 and the permeable layer 3 contain several pores. When water accumulates on the pavement layer 4, it can permeate into the road structure through these pores, achieving rapid drainage. The water that permeates into the road structure is stored in the water-retaining layer 2. When the external temperature is too high, causing the pavement temperature to rise, the water in the water-retaining layer 2 can evaporate to the outside of the road structure through the pores in the pavement layer 4 and the permeable layer 3. Through the principle of heat absorption during evaporation, the temperature of the road structure is lowered, thus regulating its temperature. Furthermore, the evaporated water vapor increases the humidity in the surrounding air. Curbstones 5 are fixedly connected to both sides of the base layer 1, and the water-retaining layer 2, the permeable layer 3, and the pavement layer 4 are laid between the two curbstones 5. The curbstones 5 protect the underlying structure of the road, improving its service life.
[0020] like Figure 2As shown, the two curb plates 5 are provided with cavities 6, which are connected with the municipal drainage structure to assist drainage, and the top of the cavity 6 is fixedly connected with a screen 7, which can intercept the garbage on the road surface to prevent the garbage from entering the cavity 6 and causing the cavity 6 to be blocked by foreign matters, thereby improving the practicability. The top surface of the road surface layer 4 is arc-shaped, and the road surface curvature does not affect the normal passing of vehicles and pedestrians. The top of the curb plate 5 is provided with a plurality of drainage openings 12, which are communicated with the cavity 6. The arc-shaped surface can make the accumulated water flow along the arc-shaped surface to the drainage openings 12 on the two curb plates 5, thereby draining the water through the cavity 6 in the curb plate 5, avoiding the accumulation of water due to excessive rainfall, and improving the drainage effect. The water storage layer 2 is provided with a drainage pipe 8, and a plurality of water inlets 9 are formed on the two sides of the drainage pipe 8. The two ends of the drainage pipe 8 extend into the cavity 6 and are communicated with each other. When the accumulated water in the water storage layer 2 reaches a certain storage capacity, the excess water in the water storage layer 2 can enter the drainage pipe 8 through the water inlets 9 and then enter the cavity 6 in the curb plate 5 from the two ends of the drainage pipe 8, thereby avoiding the excessive water in the water storage layer 2 affecting the permeability of the road surface and improving the drainage effect.
[0021] As shown in the drawings, Figure 2 The water storage layer 2 and the base layer 1 are provided with a waterproof plate 10, which can protect the base layer 1 and prevent the base layer 1 from being soaked in water for a long time, thereby prolonging the service life of the road structure, reducing resource waste, and improving the practicability. The waterproof plate 10 is provided with a plurality of protrusions 11 near one end of the water storage layer 2. The protrusions 11 are in the shape of a convex polygon, and the top end of the protrusion 11 is arc-shaped. When the road surface bears pressure, the pressure intensity on the waterproof plate 10 is reduced, thereby prolonging the service life of the waterproof plate 10.
[0022] Working principle:
[0023] In heavy rain, the rain falling on the road surface can penetrate into the inside of the road structure through the pores in the road surface layer 4 and the water permeable layer 3 and be stored in the water storage layer 2. As the rainfall increases, the raindrops accumulate on the road surface to form accumulated water. At this time, the surface of the road surface layer 4 is arc-shaped, so the rainwater accumulated on the road surface flows along the arc-shaped surface of the road surface layer 4 to the two curb plates 5 and enters the cavity 6 through the screen 7 and is discharged into the municipal drainage system.
[0024] The above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above embodiment. Any technical solution falling within the scope of the present application should be considered within the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principles of the present application should also be considered within the protection scope of the present application.
