Its core idea is to make the city have the ability of "absorbing water, storing water, purifying water and releasing water" like a sponge, so as to cope with the problems of water shortage, urban waterlogging and flood caused by urbanization.
[0003] In traditional urban design, due to the use of a large number of hardening ground and impermeable materials, rainwater cannot quickly penetrate into the underground, resulting in water flow being quickly discharged to the drainage system, which is easy to cause waterlogging, flood and other problems. Sponge city can absorb, store and slowly release rainwater like a sponge through transformation and planning, reducing the negative impact of rainwater on urban environment.
[0004] In the current water-permeable pavement, rainwater penetrates into the groundwater layer through the water-permeable material on the pavement, but when the rainfall in the city is large, the water-permeable efficiency of the water-permeable material is not enough to discharge all the rainfall downward, which leads to urban waterlogging and reduces the use effect of the water-permeable pavement of sponge city. In addition, when there are solid wastes in rainwater, the water-permeable material on the water-permeable pavement will be blocked, resulting in a decrease in the absorption rate of rainwater.

[0033] like Figures 1 to 7 As shown, this sponge city permeable pavement effectively improves the drainage capacity of the permeable pavement through the innovative design of permeable bricks 1 and the cooperation of drainage components 3. Specifically, the upper surface of the permeable bricks 1 is provided with multiple protrusions 2, which ensures that the upper piston 304 will not be damaged by pedestrians and vehicles when multiple permeable bricks 1 are spliced together to form the pavement, while also enhancing the compressive strength of the pavement. The lower surface of the permeable bricks 1 is provided with multiple drainage holes 8, and the drainage components 3 are installed inside. The drainage components 3, through the cooperation of the lower piston 301, connecting rod 302, float 303 and upper piston 304, can automatically adjust the opening and closing of the drainage holes when water infiltrates and accumulates below the permeable bricks 1, so as to drain the accumulated water in time and prevent water retention. This adaptive drainage system can automatically adjust according to changes in water level to ensure that the pavement always maintains good drainage performance, especially during periods of heavy rainfall, avoiding pavement damage or waterlogging caused by water accumulation. Furthermore, the buoy 303 design ensures the drainage system remains balanced under varying water levels, demonstrating strong adaptability. This not only improves the drainage efficiency of permeable pavements but also extends their lifespan and reduces subsequent maintenance costs. The overall design contributes to achieving the goals of a sponge city, effectively improving urban drainage systems, alleviating urban flooding, and providing reliable technical support for rainwater recycling.
[0034] As Figure 3 and Figure 5 shown, the drainage assembly 3 in the present embodiment also includes a water inlet hole 305, which is opened on the surface of the upper piston 304, and the length of the water inlet hole 305 is less than the length of the upper piston 304. The provision of the water inlet hole 305 can provide a channel for controlling the flow of water into the drainage system when the upper surface of the permeable brick 1 receives precipitation or percolation water. Since the length of the water inlet hole 305 is less than the length of the upper piston 304, water flow can only enter the internal area of the permeable brick 1 through the water inlet hole 305, thereby avoiding the situation that too much water cannot be absorbed by the rainwater above the permeable brick 1. After the water flow enters the permeable brick 1, it enters the ground through the lower drainage hole 8. The beneficial effect of this design is that the water inlet hole 305 is beneficial to quickly drain the rainwater on the road surface when there is too much rain, improving the stability of the system. At the same time, the design of the water inlet hole 305 simplifies the structure of the drainage system, enhances the adaptability of the system, avoids the uneven distribution of water flow at different water levels, and thus improves the overall performance of the permeable pavement. This design not only enhances the drainage effect of the pavement, but also improves the functionality and durability of the sponge city permeable pavement.
[0035] First, insert the first clamping block 4 on one side of a permeable brick 1 between the two second clamping blocks 5 of another permeable brick 1, and connect multiple permeable bricks 1 into a permeable pavement in the city through the above method. When it rains in the city, rainwater enters the first water inlet groove 6 through the second water inlet groove 13, and then enters the internal cavity of the permeable brick 1. At this time, the anti-litter mesh cover 12 can block the solid litter carried in the rainwater outside. When enough rainwater is collected in the internal cavity of the permeable brick 1, the rainwater will generate buoyancy to push the float 303 inside the internal cavity of the permeable brick 1 upward, and the float 303 drives the connecting rod 302 to move upward, which makes the upper piston 304 move upward, so that the water inlet hole 305 is higher than the upper surface of the permeable brick 1. At this time, rainwater can not only enter the permeable brick 1 from the second water inlet groove 13, but also enter the internal cavity of the permeable brick 1 through the water inlet hole 305. When the connecting rod 302 moves upward, the lower piston 301 will also move upward synchronously, so that the lower piston 301 moves away from the lower drainage hole 8, and the lower drainage hole 8 processed below the permeable brick 1 is opened. At this time, the rainwater collected in the permeable brick 1 will be discharged from the permeable brick 1 through the lower drainage hole 8, and the rainwater will be filtered and absorbed by the filter layer 9, the water storage layer 10 and the base layer 11 below the permeable brick 1.
[0036] As Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the embodiments also include first clamping blocks 4 and second clamping blocks 5, two of the first clamping blocks 4 are respectively provided on two side walls of the water permeable brick 1, and the other two side walls of the water permeable brick 1 are provided with the second clamping blocks 5. The first clamping blocks 4 and the second clamping blocks 5 firmly splice the adjacent water permeable bricks 1 together through clamping cooperation to form a continuous and stable water permeable pavement structure. Specifically, the design of the first clamping blocks 4 and the second clamping blocks 5 enables the water permeable bricks 1 to be connected through simple insertion or clamping, without the need for complex fixing or bonding processes, which improves the paving efficiency and ensures the stability after splicing.
[0037] The cooperation of the first clamping blocks 4 and the second clamping blocks 5 not only ensures the stable splicing of the water permeable bricks 1 in the horizontal direction, but also effectively resists the displacement or misalignment between the water permeable bricks 1 under external force, avoiding the loosening or unevenness of the pavement. The design of this clamping structure simplifies the installation process of the water permeable bricks 1 and improves the overall compressive resistance and durability of the water permeable pavement, especially in heavy traffic road environments, which can better maintain the tightness of the water permeable bricks 1 and the pavement form. In addition, this structure also has a certain flexibility, which can adjust the arrangement of the water permeable bricks 1 as needed to adapt to different paving needs.
[0038] The beneficial effects of this design are that in addition to improving the stability and durability of the pavement, the structure of the clamping blocks makes it more convenient to replace and maintain the water permeable bricks 1, reducing maintenance costs. For damage to the water permeable bricks 1 that may occur due to long-term load, environmental factors, or natural wear and tear in daily use, users can quickly replace the local water permeable bricks 1 to ensure that the pavement is always in good functional condition, thereby prolonging the service life of the water permeable pavement and reducing the overall maintenance burden.
[0039] Further, the second clamping blocks 5 are provided with two groups on the same side of the water permeable brick 1, and the spacing between the two groups of second clamping blocks 5 matches the size of the first clamping blocks 4. Through this design, the two groups of second clamping blocks 5 can form precise clamping cooperation with the first clamping blocks 4, ensuring that the water permeable bricks 1 always maintain consistent spacing and docking accuracy during the paving process. The spacing of the two groups of second clamping blocks 5 matches the size of the first clamping blocks 4, ensuring that the clamping structure between adjacent water permeable bricks 1 is stable and reliable, thereby avoiding the possibility of loose clamping or misalignment over a long period of use.
[0040] This clamping design not only improves the splicing accuracy of the water permeable bricks 1, but also enhances the overall stability and durability of the water permeable pavement. Due to the high cooperation accuracy between the first clamping blocks 4 and the second clamping blocks 5, the connection between the water permeable bricks 1 is more secure. In addition, the matching design of the spacing and size of the clamping blocks can effectively disperse the stress of the water permeable bricks 1 during the stress process, improve the compressive resistance and shock resistance of the water permeable bricks 1, and prolong the service life of the water permeable pavement.
[0041] The beneficial effects of this design also lie in the ease of maintenance and repair. When the pavement is damaged or needs to replace part of the water permeable brick 1, the user can conveniently disassemble the damaged water permeable brick 1 without affecting the integrity of the surrounding water permeable brick 1. Through a simple disassembly and replacement process, the function of the water permeable pavement can be quickly restored, reducing the long-term maintenance cost. In addition, due to the design of the clamping structure, the construction process is simplified, reducing the dependence on traditional paving technology, making the water permeable pavement more quickly and economically applied to various urban construction and repair projects.
[0042] As shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 , in this embodiment, the surface of the first clamping block 4 is processed with a first water inlet groove 6, and the surface of the second clamping block 5 is processed with a second water inlet groove 13. When a plurality of water permeable bricks 1 are spliced together, the first water inlet groove 6 corresponds to the position of the second water inlet groove 13, forming a continuous water flow channel. This design makes the first clamping block 4 and the second clamping block 5 after splicing the water permeable brick 1 can better guide the rainwater or permeable water to flow along the first water inlet groove 6 and the second water inlet groove 13, effectively improving the overall water permeability and drainage efficiency of the pavement.
[0043] Specifically, the arrangement of the first water inlet groove 6 and the second water inlet groove 13 can ensure smooth water flow through the joint area when the water permeable bricks 1 are spliced, avoiding water retention or uneven distribution caused by improper joint or unreasonable design. Through such structural design, water flow can quickly flow into the drainage system inside the water permeable brick 1 from the connecting block of the water permeable brick 1, further accelerating the penetration and discharge of water in the pavement, reducing the risk of waterlogging and waterlogging. The design of the water inlet groove provides protection in terms of drainage performance.
[0044] In addition, the design of the water inlet groove makes the distribution of water flow on the surface of the pavement more uniform, avoiding the situation of local water accumulation. This design helps to improve the functionality of the water permeable pavement, especially in the environment of heavy rainfall or heavy rainfall, it can improve the absorption and discharge capacity of the water permeable pavement to rainwater, ensuring the normal use function of the pavement. For daily use of rainwater discharge and management, the design of the water inlet groove can effectively guide the water flow into the water permeable brick 1, avoiding water overflow or retention, thereby reducing the need for maintenance and repair in the later period.
[0045] In summary, the cooperation of the first water inlet groove 6 and the second water inlet groove 13 not only enhances the sealing and stability of the spliced water permeable brick 1, but also optimizes the management of water flow, which helps to improve the drainage effect and adaptability of the water permeable pavement in the sponge city.
[0046] AsFigure 4 and Figure 5 As shown in FIG. 7 and FIG. 8, the present embodiment further comprises a limiting assembly 7, which comprises a vertical rod 701, a clamping block 702 and a clamping groove 703. Specifically, the inner wall of the lower drainage hole 8 is provided with a clamping groove 703, the clamping block 702 slides in the clamping groove 703, and the clamping block 702 is fixedly connected with the vertical rod 701, and the vertical rod 701 is fixedly connected with the lower piston 301. The arrangement of the limiting assembly 7 can effectively limit the movement range of the lower piston 301, ensure that the lower piston 301 maintains a stable movement trajectory during the drainage process, and avoid the lower piston 301 from being offset or stuck due to external force, thereby ensuring the normal work of the drainage assembly 3.
[0047] Specifically, the cooperation of the clamping groove 703 and the clamping block 702 can accurately control the up-down movement of the lower piston 301, ensure that the position and movement trajectory of the lower piston 301 during the sliding process in the lower drainage hole 8 are effectively limited, avoid unnecessary offset or sticking of the lower piston 301 during drainage, and ensure smooth drainage process. The connection of the vertical rod 701 and the lower piston 301 ensures that the overall structure of the drainage assembly 3 is more compact, and improves the durability and stability of the drainage system. When the water level inside the drainage system changes, the limiting structure of the vertical rod 701 and the clamping block 702 will limit the sliding range of the lower piston 301, so that the drainage process is always in the best working state, avoiding instability caused by excessive movement of the lower piston 301.
[0048] The design of the limiting assembly 7 has the following beneficial effects: first, it can ensure the stable sliding of the lower piston 301, avoid affecting the working efficiency of the drainage system due to excessive sliding or sticking, and ensure that the drainage performance of the permeable pavement always remains in the best state. Second, the limiting assembly 7 simplifies the design of the drainage assembly 3, making the overall structure more compact, stable, and enhancing the reliability of the permeable pavement in long-term use. Finally, the setting of the limiting assembly 7 not only improves the self-adaptive ability of the drainage assembly 3, but also reduces wear and failure caused by long-term use or environmental factors, prolongs the service life of the permeable pavement and the drainage assembly 3, and reduces the cost of later maintenance.
[0049] Therefore, through the precise design of the limiting assembly 7, not only the working efficiency of the drainage system is improved, but also the functionality and maintainability of the permeable pavement are enhanced, providing more stable and durable technical support for the construction of sponge city.
[0050] When the float 303 drives the lower piston 301 to move upward in the above manner, the lower piston 301 synchronously drives the vertical rod 701 to move, and the vertical rod 701 drives the lower clamping block 702 to move. Since the clamping block 702 moves in the clamping groove 703, when the float 303 moves upward, the clamping block 702 can ensure that the lower piston 301 does not deviate from the position of the lower drain hole 8, avoiding the situation that the lower piston 301 cannot block the lower drain hole 8 after the rainwater is discharged.
[0051] As shown in Figure 6 The present embodiment further includes a filter layer 9, the lower end of the water permeable brick 1 is provided with the filter layer 9, the lower end of the filter layer 9 is provided with a water storage layer 10, and the lower end of the water storage layer 10 is provided with a foundation layer 11. The multi-layer structure design effectively enhances the overall functionality and drainage performance of the water permeable pavement.
[0052] Specifically, the design of the filter layer 9 can effectively filter the water flow entering the inside of the water permeable brick 1, remove impurities such as silt and particulate matter in the water, and prevent them from clogging the drainage system. The setting of the filter layer 9 ensures that the water flow does not decrease the drainage performance due to the accumulation of impurities during the long-term use of the water permeable pavement. The filter layer 9 as the connecting layer between the filter layer 9 and the water storage layer 10 can smoothly transition the water flow, avoid the uneven distribution caused by the rapid change of the water flow between different layers, and ensure the stable flow of the water flow into the water storage layer 10, preparing for the next step of discharge.
[0053] The setting of the water storage layer 10 can temporarily store the permeated water in order to slowly discharge when the rainfall is too large, reducing the pressure of the urban drainage system. The water storage layer 10 is usually designed as a porous structure with large pores, which can accumulate rainwater in a short time and release the stored water according to the needs of the drainage system, achieving the purpose of regulating water flow and avoiding water flow peaks. The foundation layer 11 provides solid support, ensuring the stability and durability of the entire water permeable pavement system. The setting of the foundation layer 11 can effectively bear the traffic load and external pressure, and ensure that the water permeable pavement is not easy to deform or settle.
[0054] Among them, the filter layer 9 is composed of relatively coarse sand and gravel, the water storage layer 10 is composed of foam concrete water storage material, and the foundation layer 11 is composed of water permeable concrete.
[0055] The multi-layer structure has the beneficial effect of effectively improving the drainage efficiency and water storage capacity of the permeable pavement, while increasing the adaptability and long-term stability of the pavement system. The filter layer 9 ensures smooth and unobstructed water flow, while the water storage layer 10 effectively alleviates the impact of instantaneous rainfall on the urban drainage system and reduces the risk of waterlogging. The solid support of the base layer 11 ensures the long-term performance of the pavement, and the overall design not only improves the water management problem of the city, but also improves the sustainability and functionality of the permeable pavement, in line with the construction goal of the sponge city.
[0056] As shown in Figure 7 The anti-litter mesh cover 12 is placed in the gap between the permeable bricks 1 and covers the upper part of the second water inlet groove 13. The design of the anti-litter mesh cover 12 helps to prevent debris and litter from entering the internal system of the permeable brick 1, avoiding the accumulation of debris during the water flow process, thereby ensuring the long-term stable operation of the drainage system.
[0057] Specifically, the anti-litter mesh cover 12 is arranged in the gap between the permeable bricks 1, which can effectively prevent large debris (such as leaves, plastic bags, litter, etc.) from entering the second water inlet groove 13, preventing it from blocking the water flow channel or polluting the internal structure of the water storage layer 10 and the drainage assembly 3. Since the anti-litter mesh cover 12 is located just above the second water inlet groove 13, it can directly limit the entry of debris into the water inlet groove and subsequent drainage channel, thereby ensuring the cleanliness of the water flow into the system and improving the drainage efficiency and water quality of the permeable pavement.
[0058] The design of the anti-litter mesh cover 12 not only reduces the drainage system failure caused by debris blockage, but also reduces the difficulty of later maintenance. Because the debris accumulates on the surface of the mesh cover, it only needs to be cleaned regularly, without the need for large-scale cleaning of the drainage assembly 3 inside the permeable brick 1. In this way, the service life of the permeable pavement can be extended, and unnecessary maintenance and cleaning work can be reduced.
[0059] In addition, the design of the anti-litter mesh cover 12 can also improve the adaptability of the system, especially in urban green belts, streets or other environments prone to litter accumulation, which can effectively protect the drainage system from external pollution and ensure its good working condition at all times. The beneficial effect of this design is that it not only improves the drainage function and water quality management of the permeable pavement, but also reduces the maintenance cost in the long-term operation.
[0060] In this embodiment, the upper piston 304 is arranged within the distance between the two protrusions 2. Through this design, the upper piston 304 can freely slide between the protrusions 2 on the upper surface of the permeable brick 1, thereby further enhancing the drainage and water flow control capability of the permeable brick 1.
[0061] The advantage of such design is that it can ensure the movement of the upper piston 304 is not disturbed by external forces and is always within a stable distance of the two protrusions 2, avoiding the upper piston 304 from being misaligned or displaced during the drainage process, which affects the drainage performance. Through such cooperation, the movement of the upper piston 304 can be more stable, which helps to regulate the flow direction and flow rate of water in the permeable brick 1, ensuring that water can be timely and effectively infiltrated or drained from the system.
[0062] In addition, the design of the protrusions 2 can improve the stability of the road surface, preventing the upper piston 304 from shifting or loosening during use. The design of the upper piston 304 being positioned between the protrusions 2 also makes the drainage system more compact and reasonable in structure, while enhancing the adaptability of the system in different environments, especially when facing different water flow pressures and environmental changes, it can effectively respond to water level changes and maintain the stable operation of the drainage system.
[0063] The beneficial effect of this design is that, in addition to improving the internal drainage efficiency of the permeable brick 1, it also enhances the durability and stability of the overall permeable road surface. Through precise cooperation and position adjustment, it reduces drainage failures and uneven water distribution caused by improper structure or displacement, thereby improving the drainage performance and service life of the permeable road surface.
[0064] The above specific embodiments do not constitute a limitation on the scope of protection of the present application. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
