[0005] In order to solve the current problems of rainwater purification and storage, lawn conservation, etc., the present invention provides a rainwater storage system with the functions of filtering, purifying and collecting rainwater, which can effectively overcome the problems of existing urban drainage systems when heavy rains cause water accumulation. The pipe network system cannot solve the problems of water system pollution caused by rainwater runoff, waterlogging caused by heavy rainstorm runoff, and safety hazards caused by icy urban roads. automatic control of

Embodiment 1
[0024] Such as figure 1 As shown, the regulation and storage system with rainwater filtration, purification and collection functions, including permeable and anti-slip surface layer (1), permeable concrete (2), sidewalk rainwater collection temporary storage layer (3), curbstone (4), the upper part of the curbstone Cavity rainwater storage layer (5), curb rainwater inlet (6), motor vehicle road (7), asphalt pavement (8), filtration and purification device (9), aqueduct (10), leveling layer (11) , graded gravel layer (12), activated carbon core filter layer (13), water purification layer (14), non-woven geotextile layer (15), water level sensor (16), temperature and humidity sensor (17), controller ( 18), regulation and storage tank (19), water pump (20), suction pipe (21), rotary nozzle (22), rainwater collection module (23), drainage pipe 1 (24), lawn (25), planting soil layer (26), permeable sand layer (27), gravel coarse sand layer (28), drainage pipe (29), cushion layer (...
Embodiment 2
[0033] Such as figure 2 As shown, when the road has a slope, the entire road structure is preferentially perpendicular to the direction of the slope, and other structures are the same as in Embodiment 1.
Embodiment 3
[0035] Such as image 3 As shown, this embodiment is the same as figure 1 The embodiments in the above are basically the same in structure and principle, the difference is that the pavement structure proposed in this embodiment is generally applicable to some hard roads with small required loads in parks, schools, communities, and squares. There are few cars, bicycles, motorcycles and pedestrians, so the load required by the road surface is small, so the road surface does not need to use asphalt pavement (8), but can be paved with bricks with better quality and higher hardness. The structure can also be used as some roads with less traffic and less load in parks, schools, communities, and squares.

Abstract
The invention belongs to the technical control field of water collection and drainage, rainwater filtration, purification, regulation and storage, and particularly relates to a regulation and storage system with functions of rainwater filtration, purification and collection. Lawns, storage tanks, municipal pipe networks, and both sides of motor vehicle roads are respectively provided with curbstones in the shape of rectangular troughs. Below the non-slip surface layer, there is a double-layer sidewalk rainwater collection temporary storage layer to collect rainwater, and a graded gravel layer, activated carbon core filter layer, water purification layer and non-woven geotextile layer to filter seepage water. Through the collection, purification, storage, sewage interception and discharge of rainwater on the road surface, the present invention realizes the goals of peak shaving and storage, lawn conservation and water ecological restoration, and has important reference significance for the construction of "sponge city".
Description
technical field [0001] The invention belongs to the technical control field of water collection and drainage, rainwater filtration, purification, regulation and storage, and in particular relates to a regulation and storage system with functions of rainwater filtration, purification and collection. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's 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 stormwater system construction". When it rains, it absorbs, stores, infiltrates, filters, and purifies water, and "releases" the stored water and uses it when necessary. [0003] As an important method of "ecological drainage", permeable pavement has become an important part of road drainage design. Permeable pavement is suitable for sidewalks, ...
