Description

Technical Field

[0001] This utility model relates to the field of urban road system technology, specifically a sponge city road system with water storage function. Background Technology

[0002] Sponge city road systems are a design concept and engineering practice for urban roads that draws on the natural characteristics of sponges to enable urban roads to perform functions similar to sponges in terms of rainwater collection, storage, purification, infiltration, and utilization.

[0003] Currently, most existing urban road drainage systems adopt the traditional single-pipe drainage model. Rainwater, after collection, is often directly discharged into sewers. This drainage method may be sufficient when rainwater flow is low, but during heavy rainfall, the drainage pipes are prone to overload, leading to poor drainage and frequent urban flooding. Furthermore, with the acceleration of urbanization, the hardening of urban surfaces is becoming increasingly serious. Green spaces and soil that could naturally infiltrate rainwater are being replaced by impermeable materials such as concrete and asphalt, making it difficult for rainwater to penetrate into the ground. Therefore, this utility model provides a sponge city road system with water storage capabilities. Utility Model Content

[0025] Please see Figure 1-3 ,

[0026] Example 1: A sponge city road system with water storage function includes an urban road 1, a permeable pavement layer 3, a sewage interception trough 5, a well-type water storage component, and a rainwater filtration component. The well-type water storage component is located on the side of the pavement layer 3 away from the urban road 1, and the rainwater filtration component is located at the bottom of the permeable pavement layer 3. The urban road 1 serves as the main carrier of urban traffic, undertaking the function of vehicle and pedestrian passage. The well-type water storage component is the main part of the system for storing rainwater. When rainwater permeates through the permeable pavement layer and the rainwater filtration component, the rainwater that has undergone preliminary treatment and filtration will be collected in the water storage well for subsequent use or discharge. The rainwater filtration component, through a multi-layer filtration structure such as permeable gaps, sand layers, and gravel layers, can effectively remove pollutants such as suspended solids, organic matter, and heavy metals from the rainwater, thereby improving the quality of the rainwater.

[0027] The city road 1 has a surface layer 2 on both sides, which is in direct contact with pedestrians and provides a smooth, wear-resistant, and non-slip walking surface. The bottom of the surface layer 2 is a permeable pavement layer 3, which is permeable and allows rainwater to infiltrate and be stored or discharged through the underlying structural layer. The city road 1 is connected to the surface layer 2 on both sides by rainwater inlets 4, which are used to collect rainwater on the road surface and direct it into the intercepting trough below. The bottom of the rainwater inlets 4 is a intercepting trough 5, which is used to initially intercept and purify the rainwater, removing impurities and pollutants from the rainwater and preventing it from entering the drainage system and causing blockage or pollution. A guide pipe 6 is provided on one side of the intercepting trough 5, which is used to guide the rainwater in the intercepting trough into the permeable pavement layer to realize the reuse or discharge of rainwater. The other side of the guide pipe 6 is connected to the permeable pavement layer 3.

[0028] In this embodiment, a rainwater filtration assembly is provided at the bottom of the permeable pavement layer 3. The rainwater filtration assembly includes permeable gaps 7, a sand layer 8, and a gravel layer 9. The permeable gaps 7 at the bottom of the permeable pavement layer 3 provide channels for rainwater infiltration, increasing the amount of rainwater infiltration. The sand layer 8 at the bottom of the permeable gaps 7 further filters and purifies the rainwater, removing fine impurities. The gravel layer 9 at the bottom of the sand layer 8 provides storage space for rainwater and enhances the stability and permeability of the entire structure.

[0029] In this embodiment, a manhole cover 10 is provided on the top of the surface layer 2 on the side away from the urban road 1. The manhole cover 10 is used to seal the water storage well body to prevent debris from entering and to protect the internal structure. A water storage well body 11 is provided at the bottom of the manhole cover. The water storage well body 11 is used to store rainwater for irrigation, road cleaning and other purposes, so as to realize the reuse of rainwater. A water outlet side 12 is provided on the front side of the water storage well body 11. The water outlet side 12 is used to discharge the stored rainwater for use. A rainwater channel 13 is provided on the water outlet side 12. The rainwater channel 13 connects the water storage well body and the external water facilities to ensure that the rainwater can flow out smoothly and be used.

[0030] In this embodiment, a connecting pipe 14 is provided at the connection between the gravel layer 9 and the water storage well body 11. The connecting pipe 14 allows rainwater to flow from the gravel layer into the water storage well body for storage. A water-proof layer 15 is provided at the connection between the top side of the connecting pipe 14 and the permeable gap 7. The water-proof layer 15 is used to prevent rainwater from flowing directly into the soil below the gravel layer from the permeable gap, ensuring the effective use of rainwater.

[0031] It should be noted that when rainwater is generated on the urban road 1, the rainwater is first introduced into the intercepting trough 5 through the infiltration of the surface layer 2 and the collection of the rainwater inlet 4. The intercepting trough 5 performs preliminary treatment on the collected rainwater to remove impurities and pollutants. The rainwater treated by the intercepting trough 5 is then guided to the permeable pavement layer 3 for further infiltration and storage. Through the permeability of the permeable pavement layer 3, the rainwater quickly infiltrates into the permeable gaps 7 at its bottom. The sand layer 8 and the gravel layer 9 below the permeable gaps 7 further filter and store the rainwater, and it can flow into the water storage well 11 through the connecting pipe 14.

[0032] Example 2: It also includes a rainwater storage layer 16 at the bottom of the intercepting trough 5. The rainwater storage layer 16 is used to regulate and store rainwater, balance the rainwater flow, and reduce the pressure on the drainage system. An overflow pipe 17 is provided on one side directly in front of the rainwater storage layer 16. When the rainwater in the rainwater storage layer reaches a certain amount, the overflow pipe 17 discharges the excess rainwater into the system through the overflow pipe to prevent rainwater from overflowing and causing water accumulation.

[0033] In this embodiment, the top of the intercepting trough 5 is provided with an intercepting basket 18, and an overflow port 19 is provided on the intercepting basket 18. The intercepting basket 18 is used to open the overflow port 19. When the rainwater in the intercepting basket 18 reaches a certain amount, the rainwater is discharged into the rainwater storage layer 16 through the overflow port 19 for subsequent treatment. The inside of the intercepting trough 5 is provided with a support 20, which is used to place the intercepting net and support the structure of the intercepting basket to ensure that the intercepting basket can work stably.

[0034] It should be noted that when encountering a large amount of rainfall, the intercepting tank 5 may be unable to handle all the water alone. In this case, the excess rainwater will flow into the rainwater storage layer 16 through the overflow outlet 19 of the intercepting tank 5. The rainwater storage layer 16 has a large capacity and can hold a large amount of rainwater, thereby effectively relieving the pressure on the drainage system. When the water volume in the rainwater storage layer 16 reaches a certain level, the overflow pipe 17 will discharge the excess rainwater from the system in a timely manner to ensure the normal operation and stability of the entire system.

[0035] The beneficial effects of the above embodiments are as follows:

[0036] This sponge city road system with water storage function collects rainwater from urban roads 1 through rainwater inlets 4, treats it through intercepting channels 5, and then discharges it into permeable pavement layer 3. The use of permeable pavement layer 3 allows rainwater to quickly infiltrate into the ground, reducing surface runoff. The design of permeable gaps 7, sand layer 8, and gravel layer 9 at the bottom of permeable pavement layer further improves rainwater infiltration and storage capacity. In addition, when encountering a large amount of rainwater, intercepting channels 5 may not be able to handle all the water alone. At this time, the rainwater will be guided to rainwater storage layer 16 through overflow outlet 19 of intercepting channels 5. Rainwater storage layer 16 can hold a large amount of rainwater, thereby further relieving the pressure on the drainage system. The design of overflow pipe 17 ensures that excess rainwater can be discharged in time, ensuring the normal operation and stability of the entire system.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
