Description

Technical Field

[0001] The utility model relates to the technical field of road surface drainage, and more specifically, it relates to a fast-draining asphalt road surface. Background Art

[0002] Asphalt road surface, as one of the common road surfaces in municipal construction, has the characteristics of smooth surface, comfortable driving, small vibration, low noise, etc., and is widely used on roads.

[0003] The publicly disclosed CN216947704U discloses an environment-friendly asphalt road surface structure, and its technical solution includes an asphalt road, and further includes: a road shoulder and a sprinkling mechanism. The asphalt road includes a fine asphalt surface layer, and a coarse asphalt surface layer is laid on the top of the fine asphalt surface layer. An upper horizontal drainage groove is opened on the top of the coarse asphalt surface layer. The coarse asphalt surface layer uses larger particles of sand and gravel in combination with asphalt. The fine asphalt surface layer uses relatively fine particles of sand and gravel in combination with asphalt. A lower horizontal drainage groove is opened on the top of the fine asphalt surface layer. The road shoulder includes a foundation, and a water collection channel is arranged at the top of the foundation near the upper horizontal drainage groove.

[0004] In the above technical solution, the accumulated water on the surface of the coarse asphalt surface layer flows to both sides along the upper horizontal drainage groove. At the same time, the coarse asphalt surface layer using larger particle sand and gravel can accelerate the penetration speed of the accumulated water to prevent water from accumulating on the coarse asphalt surface layer, and is discharged to both sides through the lower horizontal drainage groove, which is beneficial to keeping the road surface dry and improving driving safety. However, in the above technical solution, no structure is provided in the drainage groove for cleaning the impurities in the drainage groove, resulting in the accumulation of impurities in the drainage groove during drainage, and then the drainage groove is blocked, affecting the drainage effect.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0006] Aiming at the deficiencies existing in the prior art, the purpose of the present utility model is to provide a fast-draining asphalt road surface, which solves the problem that impurities will accumulate in the drainage groove during drainage, and then the drainage groove is blocked, affecting the drainage effect.

[0007] The above technical purpose of the present utility model is achieved through the following technical solutions: a fast-draining asphalt road surface, including a road surface body and two side stones on both sides. The road surface body includes a base layer and a surface layer. There is a gap between the two side stones and the surface layer. A drainage channel is fixedly connected between the base layer and the two side stones. A cleaning component for cleaning impurities is arranged between the base layer and the two side stones. A drainage component for discharging rainwater outwards is arranged between the surface layer and the base layer.

[0008] By adopting the above technical solution, when draining water from the road surface, a part of the water will flow along the surface layer in the direction of the spacing between the side curb and the surface layer, and fall onto the cleaning component. The cleaning component separates the water from the impurities. The water separated from the impurities will continue to fall downward onto the drainage channel. At the same time, another part of the water will penetrate into the surface layer. At this time, through the drainage component, the water can be drained into the drainage channel, and the water is discharged outward through the drainage channel, thereby achieving the effect of draining the road surface. At the same time, through the cleaning component, the water and impurities can be separated, avoiding the problem of the drainage channel being blocked by impurities and improving the drainage effect.

[0009] The present utility model is further configured as: The drainage component includes water-permeable plates fixedly connected to both sides of the surface layer. Two fixing plates are fixedly connected between the two water-permeable plates. The two fixing plates are respectively connected to the surface layer and the base layer. A plurality of drainage holes are formed in the fixing plate closest to the surface layer. The two fixing plates are connected by a sand layer.

[0010] By adopting the above technical solution, when the water penetrates into the surface layer, the water will continue to penetrate downward through the drainage holes in one of the fixing plates and accumulate on the other fixing plate. At this time, the water will move towards the water-permeable plate and the water is discharged into the drainage channel through the water-permeable plate, thereby achieving the effect of discharging the water that has penetrated into the surface layer outward. At the same time, through the setting of the sand layer, the water can be filtered, avoiding the blockage of the water-permeable plate, and at the same time, the structural strength between the two fixing plates can be improved.

[0011] The present utility model is further configured as: A plurality of support frames are fixedly connected between the two fixing plates, and the plurality of support frames are fixedly connected to each other.

[0012] By adopting the above technical solution, the structural strength between the two fixing plates can be improved, avoiding the problem that the two fixing plates are bent or broken under the influence of pressure, and improving the service life of the two fixing plates.

[0013] The present utility model is further configured as: The cleaning component includes a connecting plate fixedly connected between the water-permeable plate and the side curb. A plurality of through holes are formed in the connecting plate. A limiting block is fixedly connected to the plurality of through holes. A plurality of water outlets are formed in the side wall of the limiting block. A plurality of placement grooves for collecting impurities are formed in the connecting plate.

[0014] By adopting the above technical solution, when the water enters the spacing between the surface layer and the side curb, the water will accumulate on the connecting plate. At this time, through the plurality of water outlets on the limiting block, the water and impurities can be separated from each other, and the separated water will fall into the drainage channel, while the separated impurities will enter the placement groove for collection, thereby achieving the effect of collecting the impurities mixed with the water.

[0015] The present utility model is further configured such that: the limiting block is conical.

[0016] By adopting the above technical solution, it is possible to facilitate the entry of impurities on the limiting block into the placement groove, improving the collection effect.

[0017] The present utility model is further configured such that: a drain cover is provided between the water-permeable plate and the curbstone.

[0018] By adopting the above technical solution, it is possible to prevent the connecting plate and the limiting block from being damaged, improving the service life of the connecting plate and the limiting block. At the same time, it can also prevent pedestrians from accidentally stepping into the gap, improving safety.

[0019] The present utility model is further configured such that: a fixing net is fixedly connected inside the surface layer.

[0020] By adopting the above technical solution, it is possible to improve the structural strength of the surface layer, reduce the occurrence of cracks in the surface layer, and improve the service life of the surface layer.

[0021] The present utility model is further configured such that: a waterproof layer is provided on the base layer.

[0022] By adopting the above technical solution, it is possible to prevent the base layer from coming into contact with water, reduce the erosion of the base layer, and improve the service life of the base layer.

[0023] In summary, the present utility model has the following beneficial effects: When draining water from the road surface, a part of the water will flow along the surface layer towards the gap between the curbstone and the surface layer and drop onto the cleaning assembly. Through the cleaning assembly, the water and impurities are separated from each other. The water separated from the impurities will continue to drop down onto the drainage channel. At the same time, another part of the water will penetrate into the surface layer. At this time, through the drainage assembly, the water can be drained into the drainage channel and discharged outward through the drainage channel, thereby achieving the effect of draining water from the road surface. At the same time, through the cleaning assembly, the water and impurities can be separated, avoiding the problem of the drainage channel being blocked by impurities and improving the drainage effect.
