Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pavement and relates to a drainage asphalt pavement. Background Art
[0002] Asphalt concrete pavement refers to a road surface with asphalt concrete as the surface layer. It is a mixture made by artificially selecting mineral materials with a certain graded composition (crushed stone or crushed gravel, stone chips or sand, mineral powder, etc.) and a certain proportion of road asphalt materials under strictly controlled conditions. The asphalt pavement is smooth, dust-free, waterproof and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction.
[0003] However, the existing asphalt concrete pavement will accumulate water when it rains, and vehicles may slip when passing through. At the same time, the accumulated water is easy to splash onto passers-by. Most of the current asphalt pavement drainage is directly opened with drainage holes. The drainage holes are prone to garbage accumulation and blockage, which is easy to affect the drainage effect when it rains. Utility Model Content
[0004] The utility model aims to solve the above problems in the prior art and proposes a drainage asphalt pavement.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a drainage asphalt pavement, including a base layer, the top surface of the base layer is inclined downward toward both sides, a drainage pipe is arranged on the top of the base layer, the drainage pipe is inclined along the top surface of the base layer, an asphalt layer is arranged on the base layer, and the asphalt layer is provided with a plurality of drainage ditches, and a downpipe connected to the drainage pipe is vertically arranged at the end of each drainage ditch, and the diameter of the downpipe is smaller than the diameter of the drainage pipe.
[0006] By setting a number of drainage ditches on the top of the asphalt layer, water on the road surface can enter the drainage ditches and fall into the drainage pipes from the downpipes for discharge, thus avoiding water accumulation on the road surface; the base layer and the drainage pipes are set to be inclined downward on both sides, so that the water on the road surface can be discharged from the drainage pipes on both sides, speeding up the discharge of rainwater entering the drainage pipes, thereby improving drainage efficiency and reducing water accumulation on the road surface.
[0007] In the above-mentioned drainage asphalt pavement, the top surface of the drainage ditch is provided with a drainage hole, the downpipe is located in the drainage hole, and the top surface of the drainage ditch is arranged to be inclined downward toward one side of the drainage hole. Such an arrangement enables water falling into the drainage ditch to flow along the inclined surface toward one side of the drainage hole, thereby facilitating the drainage of rainwater in the drainage ditch.
[0008] In the above-mentioned drainage asphalt pavement, the drainage hole is provided with a mounting groove with a larger hole diameter than the drainage hole, and the mounting groove is provided with a filter floor drain. The filter floor drain can block the garbage in the drainage hook to prevent the garbage from entering the downpipe and causing blockage of the downpipe.
[0009] In the above-mentioned drainage asphalt pavement, the drainage ditch and the top surface of the asphalt layer form an anti-skid portion. The provision of the anti-skid portion can increase the friction between the pavement and the vehicle tires, thereby improving the anti-skid performance of the pavement.
[0010] Compared with the prior art, the utility model sets a plurality of drainage ditches on the top of the asphalt layer, so that water on the road surface can enter the drainage ditches and fall into the drainage pipes from the downpipes for discharge, thereby avoiding water accumulation on the road surface; the base layer and the drainage pipes are set to be inclined downward on both sides, so that the water on the road surface can be discharged from the drainage pipes on both sides respectively, accelerating the discharge of rainwater entering the drainage pipes, thereby improving the drainage efficiency and reducing water accumulation on the road surface.

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0016] Example
[0017] like Figures 1 to 3 As shown, a drainage asphalt pavement includes a base layer, which is formed by pouring concrete. The top surface of the base layer is inclined downward on both sides. A drainage pipe is arranged on the top of the base layer. The drainage pipe is embedded in the base layer after the base layer is poured. The drainage pipe is fixed after the concrete solidifies. The upper end of the drainage pipe is located outside the base layer to facilitate subsequent connection with a downpipe. The drainage pipe is inclined along the top surface of the base layer, an asphalt layer is arranged on the base layer, and a plurality of drainage ditches are arranged on the asphalt layer. A downpipe connected to the drainage pipe is vertically arranged at the end of each drainage ditch, and the diameter of the downpipe is smaller than the diameter of the drainage pipe.
[0018] By setting a number of drainage ditches on the top of the asphalt layer, water on the road surface can enter the drainage ditches and fall into the drainage pipes from the downpipes for discharge, thus avoiding water accumulation on the road surface; the base layer and the drainage pipes are set to be inclined downward on both sides, so that the water on the road surface can be discharged from the drainage pipes on both sides, speeding up the discharge of rainwater entering the drainage pipes, thereby improving drainage efficiency and reducing water accumulation on the road surface.
[0019] Furthermore, the top surface of the drainage ditch is arranged to be inclined downward toward one side of the drainage hole. Such arrangement enables water falling into the drainage ditch to flow along the inclined surface toward one side of the drainage hole, thereby facilitating the drainage of rainwater in the drainage ditch.
[0020] Furthermore, the drainage hole is provided with a mounting groove with a larger hole diameter than the drainage hole, and the mounting groove is provided with a filter floor drain. The filter floor drain can block the garbage in the drainage hook to prevent the garbage from entering the downpipe and causing blockage of the downpipe.
[0021] Furthermore, the drainage ditch and the top surface of the asphalt layer form an anti-skid portion. The provision of the anti-skid portion can increase the friction between the road surface and the vehicle tires, thereby improving the anti-skid performance of the road surface.
[0022] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
