Environment-friendly sidewalk pavement structure convenient for drainage

Abstract

The invention relates to a sidewalk, and in particular, relates to an environment-friendly sidewalk pavement structure convenient for drainage, wherein the environment-friendly sidewalk pavement structure comprises a roadbed; the roadbed is paved on the bottommost layer of a road, a gravel layer is paved on the roadbed, a water permeable brick layer and a soil layer are paved on the gravel layer, the soil layer is positioned on one side of the water permeable brick layer, and green plants are planted on the soil layer; a plurality of collecting boxes are pre-buried in the gravel layer, the upper sides of the collecting boxes are open, and the collecting boxes are distributed in the length direction of the road; water outlets are formed in the water permeable brick layer in the width direction of the water permeable brick layer and communicate with inner cavities of the collecting boxes; filter screens are fixed to the openings in the upper sides of the collecting boxes, and cleaning assemblies used for cleaning the filter screens are connected into the collecting boxes; and the soil layer is provided with a water pumping mechanism used for pumping out water in the collecting boxes and discharging the water into the soil layer. The pavement structure has the advantages that the drainage speed of the pavement is increased, stored water is recycled, and the environment-friendly concept of a sponge city is met.

Description

technical field [0001] The application relates to sidewalks, in particular to an environment-friendly sidewalk surface structure that facilitates drainage. Background technique [0002] Sidewalks often accumulate water in rainy weather, causing inconvenience to pedestrians, so sidewalks are often equipped with drainage structures. [0003] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge and has good elasticity in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates, purifies water when it rains, releases the stored water and utilizes it when needed, and realizes the free migration of rainwater in the city. [0004] At present, the Chinese patent with the publication number CN109137676A discloses a sidewa...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that: the above-mentioned sidewalk surface structure is drained through ceramic permeable bricks. When encountering heavy rain, the drainage speed is slow, and there is no water storage structure, which does not conform to the environmental protection concept of sponge city
