There are sidewalks and green belts on both sides of the road. In the design process of municipal roads, in order to reduce the damage of road surface water to the road surface and the inconvenience of driving, the road surface is usually slightly inclined to the sidewalk or green belt, and a rainwater well is arranged near the sidewalk and green belt to collect and guide rainwater.

[0003] However, the existing road drainage structure may cause road cracking due to temperature changes, vehicle rolling and other factors, thereby causing water seepage and other problems. Rainwater penetrates the road surface, causing settlement and uneven settlement of the roadbed, affecting the flatness of the road and driving safety. CONTENT OF THE UTILITY MODEL

[0004] In view of the defects of the prior art, the present application provides a municipal road drainage structure, which has the advantages of reducing the risk of water seepage, etc. The existing road drainage structure may cause road cracking due to temperature changes, vehicle rolling and other factors, thereby causing water seepage and other problems. Rainwater penetrates the road surface, causing settlement and uneven settlement of the roadbed, affecting the flatness of the road and driving safety.

[0005] To achieve the above purpose, the present application provides the following technical scheme: a municipal road drainage structure, comprising a base, the inside bottom end of the base is fixedly connected with a flow guide block, the upper end of the flow guide block is fixedly connected with a plurality of support columns arranged in a straight line array, the upper end of the plurality of support columns is fixedly connected with a support plate, a plurality of first water channels arranged in a straight line array are arranged inside the support plate, the upper end of the first water channel is fixedly connected with a filter layer, the upper end of the filter layer is fixedly connected with a water-permeable base layer, the upper end of the water-permeable base layer is fixedly connected with a reinforcing net, the upper end of the reinforcing net is fixedly connected with a water-permeable surface layer, and the bottom end of the base is fixedly connected with a second water channel on both sides.

[0006] Through the above scheme, the water flow entering the inside of the base can be quickly guided to a specific direction by the flow guide block arranged at the bottom end of the inside of the base, so that the water flow flows more orderly, the drainage efficiency is improved, the water flow is effectively prevented from being disorderedly accumulated in the inside of the base, damage to the structure caused by excessive water accumulation is prevented, the first water passing grooves arranged in a straight line array are arranged through the inside of the support plate, the drainage area is increased, water can pass through more quickly, the risk of road waterlogging is reduced, the upper end of the flow guide block is connected with the support plate through the support columns arranged in a straight line array, stable and reliable support is provided for the upper structure, the water permeable base layer and the water permeable surface layer are arranged, good water permeability can be realized, rainwater can quickly penetrate through these structure layers and enter the drainage system, road waterlogging is reduced, the traffic capacity of the road in rainy days is improved, the driving conditions are improved, and the traffic safety is ensured, the accumulated water can be actively guided and quickly drained, the water seepage into the roadbed can be reduced, the problem of roadbed settlement caused by long-term soaking of the accumulated water is avoided, the stability and bearing capacity of the roadbed structure are protected, and the setting of the reinforcing net plays a role in preventing the water permeable base layer and the water permeable surface layer from cracking. In the process of using the road, due to factors such as temperature change and vehicle load, the water permeable base layer and the water permeable surface layer may crack, the reinforcing net can enhance the integrity and toughness of the structure, disperse stress, effectively prevent the generation and expansion of cracks, and further improve the durability and reliability of the drainage structure.

[0007] Further, the base is fixedly connected with drainage boxes on both sides, drainage channels are arranged at the bottom end of the inside of the two drainage boxes, and a plurality of drain nets arranged in a straight line array are arranged on the upper end of the drainage box.

[0008] Through the above scheme, the base is fixedly connected with drainage boxes on both sides, which provides additional drainage space and path for the water flow. After the water flow in the inside of the base is discharged through the second water passing grooves, part of the water flow can directly enter the drainage box, further widening the drainage channel of the water flow, effectively improving the overall drainage efficiency, and ensuring that the accumulated water can be quickly discharged in a large amount of precipitation. The drainage channels are arranged at the bottom end of the inside of the drainage box, which can quickly guide the water flow entering the drainage box to a specific direction, so that the water flow flows orderly in the drainage box, and the drainage speed is accelerated.

[0009] Further, the second water passing grooves are arranged through the two sides of the base.

[0010] Through the above scheme, the second water passing grooves arranged through the two sides of the base provide a more direct discharge channel for the water flow, the water flow can more smoothly pass through the second water passing grooves from the inside of the base to the outside of the base, the drainage flow is increased, and the drainage efficiency is effectively improved.

[0011] Further, the flow guide block is triangularly arranged, and the two ends of the flow guide block correspond to the second water passing grooves.

[0012] Through the above scheme, the diversion block is triangular, which can more effectively gather the water flow flowing into the base inside to the two sides of the diversion block, so that the water flow is more concentrated, facilitating subsequent guidance to the second water channel, improving the collection efficiency of the water flow, and reducing the dispersion and retention of the water flow in the base.

[0013] Further, the filter layer is made of geotextile material.

[0014] Through the above scheme, the geotextile has a fine fiber structure, which can effectively intercept silt, soil particles, organic impurities and the like in water. When the water flow passes through the filter layer, these impurities will be blocked by the geotextile, avoiding blockage and ensuring the smoothness of the entire drainage system.

[0015] Further, the water-permeable base layer is made of large-diameter gravel.

[0016] Through the above scheme, large-diameter gravel forms larger pores, which provide a spacious channel for water flow. When rain falls on the road surface and penetrates into the water-permeable base layer, it can quickly flow downward through these pores, improving the water permeation speed and effectively reducing road ponding, ensuring the road traffic capacity in rainy days.

[0017] Further, the reinforcing net is made of polypropylene material.

[0018] Through the above scheme, the polypropylene material can disperse the directional stress of the concrete, prevent the occurrence and development of original cracks in the concrete, and improve the impact resistance of the concrete.

[0019] Further, the water-permeable surface layer is made of water-permeable asphalt.

[0020] Through the above scheme, the water-permeable asphalt has a unique pore structure, with a large number of interconnected pores inside, allowing rainwater to quickly penetrate into the underlying structure.
