Description

Technical Field

[0001] This application relates to the field of sponge city technology, and in particular to a sponge city building structure. Background Technology

[0002] With the acceleration of urbanization and the high density of urban populations, the number of buildings and hard paved surfaces has been increasing, resulting in significant changes to the urban underlying surface. In traditional urban construction models, rainwater drainage often employs rapid discharge methods, where rainwater is quickly collected through drainage pipes and discharged into rivers and other water bodies. This method has brought about many serious problems.

[0003] Rainwater runoff has increased significantly. Because hard surfaces are difficult for rainwater to penetrate, large amounts of rainwater rapidly form surface runoff during rainfall, far exceeding the design capacity of urban drainage systems, leading to frequent urban flooding. During heavy rains, severe flooding occurs on urban roads, paralyzing traffic and seriously threatening the lives and property of residents. It also causes great inconvenience to urban commercial activities and public services, resulting in huge economic losses. Therefore, this patent requires upgrading and modification based on existing technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a sponge city building structure that overcomes these deficiencies. It aims to solve the problem of frequent urban flooding caused by the rapid formation of surface runoff during rainfall due to the difficulty of rainwater infiltration on hard surfaces, which far exceeds the design capacity of urban drainage systems. During heavy rains, severe flooding occurs on urban roads, paralyzing traffic, seriously threatening the lives and property of residents, and causing significant inconvenience to urban commercial activities and public services, resulting in substantial economic losses.

[0005] To achieve the above objectives, this application provides the following technical solution: a sponge city building structure, comprising a base layer, the bottom layer of which is filled with a filter layer, the top of which is filled with a reverse filter base layer and a soil layer, a dividing tooth fixedly provided between the reverse filter base layer and the soil layer, a green landscape that can be planted on top of the soil layer, a permeable layer filled on top of the reverse filter base layer, a diversion hole provided at the upper end of the dividing tooth near the permeable layer, a drainage pipe provided inside the filter layer, the drainage pipe extending outward through the outside of the base layer, a sedimentation well fixedly connected to the outwardly extending end of the drainage pipe, a water storage pipe fixedly connected to the lower end of one side of the sedimentation well, a water storage tank connected to the end of the water storage pipe, and a river drainage pipe fixedly connected to the upper end of one side of the sedimentation well.

[0006] As a preferred technical solution of this application, the foundation layer is constructed of reinforced concrete.

[0007] By adopting the above technical solutions, the function is to stably support the overall weight of the building, ensure that the building foundation is stable and free from displacement or settlement risk under various environmental and load conditions, and provide a solid support platform for the upper floors.

[0008] As a preferred technical solution of this application, the permeable layer is composed of permeable materials such as permeable concrete, permeable asphalt, and graded crushed stone.

[0009] By adopting the above technical solutions, these materials have a large porosity, enabling them to quickly infiltrate rainwater, reduce road runoff, and prevent water accumulation.

[0010] As a preferred technical solution of this application, the filter base layer is composed of materials such as sand and gravel.

[0011] By adopting the above technical solution, it has both a certain filtering function, which can prevent soil particles from entering the drainage base layer and prevent drainage pipe blockage; and good permeability, which allows rainwater to pass through smoothly and enter the drainage base layer for discharge. The reverse filter base layer can maintain the relative stability between the base layers during the rainwater infiltration and flow process, prevent the mixing and loss of different base layer materials, thereby ensuring the stability of the entire base layer structure and the normal operation of the rainwater collection system.

[0012] As a preferred technical solution of this application, the filter layer is mainly composed of materials with large specific surface area and adsorption capacity, such as activated carbon and zeolite.

[0013] By adopting the above-mentioned technical solutions, heavy metal ions, organic matter, and other pollutants in rainwater can be adsorbed, further improving the rainwater purification effect. For example, the porous structure of activated carbon can adsorb various organic pollutants, effectively removing odors and some harmful substances from rainwater. After removing some harmful substances from rainwater through adsorption, the rainwater quality becomes more stable, which is more conducive to subsequent storage and utilization. The type and thickness of the adsorption base layer can be adjusted according to different water quality requirements and rainwater pollution conditions.

[0014] As a preferred technical solution of this application, the soil layer has a certain porosity, which allows rainwater to infiltrate into the ground.

[0015] By adopting the above technical solutions, greenery can be planted in the soil due to its low permeability coefficient. The greenery can absorb rainwater, reduce the surface temperature, and beautify the appearance of the road surface.

[0016] As a preferred technical solution of this application, the drain pipe is provided with an inlet hole on the inner and outer side of the filter layer.

[0017] By adopting the above technical solution, the inlet holes are provided with multiple sets of equidistantly arranged on the outside of the drain pipe. Rainwater entering the filter layer can enter the drain pipe through the inlet holes and then be discharged into the sedimentation well through the drain pipe.

[0018] As a preferred technical solution of this application, the water storage tank is equipped with a capacity monitor inside, and the water storage pipe is equipped with a solenoid valve on the outside, and the solenoid valve is electrically connected to the capacity monitor.

[0019] By adopting the above technical solution, the capacity monitor can detect changes in the internal capacity of the water storage tank in real time. When the capacity monitor detects that the water storage tank is about to be full, the water storage tank control solenoid valve will be closed to stop rainwater from entering the water storage tank. At this time, the water level will rise. When it reaches the position of the river drainage pipe, the collected water will be discharged into the external river through the river drainage pipe.

[0020] The beneficial effects of this application are:

[0021] In this invention, rainwater is efficiently collected starting from the permeable layer. After being purified by the combined action of the reverse filter layer and the filter layer, part of the rainwater seeps into the soil layer to help plant growth and conserve groundwater. The other part is guided to the drainage pipe in an orderly manner. After sedimentation in the sedimentation well, it is either stored in a reservoir for subsequent non-potable water use or discharged into the river when the reservoir is full. The whole process is closely connected, simulating the natural water cycle and making full use of rainwater resources. This effectively reduces urban rainwater runoff and the risk of waterlogging, enhances the ecological resilience of the city and the sustainable use of water resources, and promotes the harmonious coexistence of the city and the natural environment.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Reference Figure 1A sponge city building structure includes a base layer 1, the bottom layer of which is filled with a filter layer 4, the top of which is filled with a reverse filter base layer 3 and a soil layer 9, a dividing tooth 7 fixedly installed between the reverse filter base layer 3 and the soil layer 9, and a green landscape can be planted on the top of the soil layer 9. The top of the reverse filter base layer 3 is filled with a permeable layer 2, and a diversion hole 8 is provided at the upper end of the dividing tooth 7 near the permeable layer 2. A drainage pipe 5 is provided inside the filter layer 4, and the drainage pipe 5 extends outward through the outside of the base layer 1. The outward extension end of the drainage pipe 5 is fixedly connected to a sedimentation well 11. A water storage pipe 13 is fixedly connected to the lower end of one side of the sedimentation well 11, and a water storage tank 14 is connected to the end of the water storage pipe 13. A river drainage pipe 12 is fixedly connected to the upper end of one side of the sedimentation well 11.

[0026] In this embodiment, as Figure 1 As shown, the foundation layer 1 is constructed of reinforced concrete. Its function is to stably support the overall weight of the building, ensure that the building foundation is stable and free from displacement or settlement risk under various environmental and load conditions, and provide a solid support platform for the upper layers.

[0027] In this embodiment, as Figure 1 As shown, the permeable layer 2 is composed of permeable materials such as permeable concrete, permeable asphalt, and graded crushed stone. These materials have a large porosity, which can quickly infiltrate rainwater, reduce road runoff, and prevent water accumulation.

[0028] In this embodiment, as Figure 1 As shown, the reverse filter base layer 3 is composed of materials such as sand and gravel. It has a certain filtering effect, which can prevent soil particles from entering the drainage base layer and prevent drainage pipe blockage. It also has good permeability, which allows rainwater to pass through smoothly and enter the drainage base layer for discharge. The reverse filter base layer can maintain the relative stability between the base layers during rainwater infiltration and flow, prevent the mixing and loss of different base layer materials, thereby ensuring the stability of the entire base layer structure and the normal operation of the rainwater collection system.

[0029] In this embodiment, as Figure 1 As shown, the filter layer 4 is mainly composed of materials with large specific surface area and adsorption capacity, such as activated carbon and zeolite. It can adsorb pollutants such as heavy metal ions and organic matter in rainwater, further improving the purification effect of rainwater. For example, the porous structure of activated carbon can adsorb a variety of organic pollutants, effectively removing odors and some harmful substances from rainwater. After removing some harmful substances from rainwater through adsorption, the rainwater quality becomes more stable, which is more conducive to subsequent storage and utilization. The type and thickness of the adsorption layer can be adjusted according to different water quality requirements and rainwater pollution conditions.

[0030] In this embodiment, as Figure 1As shown, soil layer 9 has a certain porosity, which allows rainwater to seep into the ground. Because soil layer 9 has a low permeability coefficient, it can be planted with greenery. The greenery can absorb rainwater, reduce the surface temperature, and beautify the appearance of the road surface.

[0031] In this embodiment, as Figure 1 As shown, the drain pipe 5 is located inside the filter layer 4 and has an inlet hole 6 on the outside. The inlet hole 6 has multiple sets of equidistantly arranged on the outside of the drain pipe 5. Rainwater entering the filter layer 4 can enter the drain pipe 5 through the inlet hole 6 and then be discharged into the sedimentation well 11 through the drain pipe 5.

[0032] In this embodiment, as Figure 1 As shown, a capacity monitor is installed inside the water storage tank 14, and a solenoid valve 10 is installed outside the water storage pipe 13. The solenoid valve 10 is electrically connected to the capacity monitor. The capacity monitor detects the change in the capacity inside the water storage tank 14 in real time. When the capacity monitor detects that the water storage tank 14 is about to be full, the water storage tank 14 controls the solenoid valve 10 to close, thereby stopping rainwater from entering the water storage tank 14. At this time, the water level will rise. When it reaches the position of the river drainage pipe 12, the collected water will be discharged into the external river through the river drainage pipe 12.

[0033] Working principle: Rainwater first falls into the infiltration layer 2, and due to its permeability, it quickly infiltrates downwards. Some rainwater enters different areas through the diversion holes 8 on the dividing teeth 7. Some infiltrates into the soil layer 9, where plants absorb some of the rainwater, and the remaining rainwater continues to infiltrate downwards. Another part of the rainwater continues to infiltrate downwards through the reverse filter layer 3 into the filter layer 4. The rainwater entering the filter layer 4 enters the drain pipe 5 through the inlet hole 6 on the outside of the drain pipe 5, and is then discharged into the sedimentation well 11. In the sedimentation well 11, large particles of impurities in the rainwater settle down. After sedimentation, if the water storage tank 14 is not full, the rainwater will flow into the water storage tank 14 through the water storage pipe 13 for storage, for later use, such as for irrigation, landscape water replenishment, etc. When the water storage tank 14 is about to be full, the capacity monitor controls the solenoid valve 10 to close. When the rainwater level rises to the position of the river drainage pipe 12, the rainwater will be discharged into the external river through the river drainage pipe 12.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
