Description

Wisdom city sponge road infiltration system

Technical Field

The utility model belongs to the field of smart cities, and particularly relates to a sponge road water seepage system for a smart city.

Background

In recent years, along with the rapid development of urbanization in China, the original permeable natural underlying surface is gradually replaced by the impermeable ground surfaces such as cement and asphalt in urban areas, and the proportion of the impermeable ground surfaces in the urban ground surfaces is continuously increased. The change of the water permeability of the underlying surface causes the urban surface runoff infiltration rate to be greatly reduced and the time for forming a flood peak to be shortened, thereby generating great influence on the natural circulation process of the water body and further causing a series of urban environmental problems such as water resource shortage, urban waterlogging, "urban heat island", water ecosystem destruction, water body pollution and the like.

In order to deal with the outstanding urban environmental problems, the national level gradually proposes and pushes the construction of sponge cities which take 'stagnation, storage, seepage, purification, use and discharge' as main rainfall flood treatment means. The road of the waterproof building district with a certain area is also an important 'contributor' to the urban environmental problem, most of the road runoff of the building district is collected by a rainwater inlet and a rainwater well which are arranged on the roadside and then is collected into a municipal drainage pipe network through a rainwater pipe network, and is discharged into natural water after being treated by a sewage treatment plant, but the treatment of the road runoff of the building district not only increases the drainage pressure of the municipal drainage pipe network and the treatment pressure of the sewage treatment plant, but also is not beneficial to the recharge of underground water and the on-site utilization of rainwater resources, although some roads of the building district are spongingly modified to a certain extent (such as replacing permeable pavement and building a water storage module), the road surface is damaged more in the modification process, and the modification cost is higher.

Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.

As shown in fig. 1, the smart city sponge road water seepage system comprises a water collecting unit, a water filtering unit and a water storage unit, wherein the water collecting unit comprises water collecting pipelines 1 positioned at two sides of a sponge road 7 and a water collecting pool 2 positioned at the bottom end of the sponge road 7, and the water collecting pool 2 is communicated with the water collecting pipelines 1; the water filtering unit comprises a filtering tank 3, and the water collecting tank 2 is communicated with the filtering tank 4 through a water conveying pipeline 9; the water storage unit comprises a water storage tank 5 and a first water pipeline 6, the filtering tank 4 is communicated with the water storage tank 5 through a water conveying pipeline 9, and the water storage tank 5 is communicated with a water using device through the first water pipeline 6; and filter screens 3 are arranged at two ends of the water conveying pipeline 9.

The using principle of the utility model is that the water in the sponge path 7 is collected and precipitated by the water collecting unit, filtered by the water filtering unit, and finally conveyed to the water storage tank 5 by the water filtering unit, and conveyed to the water using device by the first water pipeline 6 of the water storage tank 5, so that the water permeating in the sponge path 7 is produced and sold.

The upper end of the water collecting pipeline 1 is provided with a sewer grid, and the horizontal height of the sewer grid is lower than that of the sponge road. The sewer grille 10 is arranged to reduce the flow of the rest water-insoluble garbage on the sponge road 7 into the water collecting pipeline 1 and prevent the garbage from entering the whole sponge road water seepage system; the sewer grille 10 is arranged at a height lower than the height of the surface of the sponge road 7, and aims to guide water, so that most of water can directly flow into the water collecting pool 2 through the water collecting pipeline 1, and the accumulation of water on the sponge road 7 is reduced.

A coarse filter layer 11 is arranged between the water collecting pipeline 1 and the water collecting tank 2. The setting of coarse filtration layer 11 plays the water that gets into to water collecting pipe 1 and carries out coarse filtration impurity, reduces the filter pressure of sponge road infiltration system (filter screen 3).

The water collecting tank 2 and the filtering tank 3 are both provided with independent second water pipelines 8. Although the water in the water collecting tank 2 and the water in the filtering tank 4 are not clean enough, in order to reduce the pressure of the water stored in the water storage tank 5, the water collecting tank 2 and the filtering tank 4 can also be used for washing vehicles or sewers, and the like, so that the water can be directly delivered to places with corresponding water requirements by butting the second water using pipeline 8.

As shown in fig. 2, the pipe wall of the water inlet and outlet of the conveying water pipeline 9 is provided with a leak hole 12, and the filter screen 3 is wrapped at two ends of the water inlet and outlet of the whole conveying water pipeline 9. This ensures that each time water is transported in the delivery water conduit 9, impurities in the water are filtered once, the cleaner the water stored is the further it reaches the following reservoir.

An electromagnetic valve 13 is arranged at the water inlet of the water storage tank 5. The solenoid valve 13 sets up on carrying water pipeline 9 walls, prevents that the water that gets into in the tank 5 from surpassing tank 5 outflow and storage water yield, avoids whole sponge road infiltration system's paralysis, so has connect independent second water pipeline 8 in the catch basin 2 and the filtering ponds 4 outward, reduces tank 5's water storage pressure.

The sponge road 7 is composed of two or more layers of water permeable pavement materials. Multilayer water permeability pavement material plays certain filtration impurity effect to the water on the sponge way 7, and the water through water permeability pavement material can directly get into in the catch basin 2. The water permeable pavement material comprises natural stones, water permeable floor tiles, water permeable asphalt pavement, water permeable ceramic pavement bricks, water permeable concrete and the like.

1. original 7-road pavement construction of the sponge road is not changed, and the whole smart city sponge road water seepage system is simple in structure and low in construction cost;
