[0002] Sponge city refers to a city that can adapt to environmental changes and deal with natural disasters caused by rainwater like a sponge, and has good elasticity. It can also be called a "water-elastic city". Its core lies in enhancing the city's surface's ability to absorb, store and release rainwater, effectively controlling rainwater runoff, achieving source emission reduction, rainwater peak reduction and rainwater resource utilization, thereby improving the city's flood control and drainage capabilities and improving the urban ecological environment.

[0003] In the existing technology, the construction of sponge cities follows the six-word principle of "infiltration, retention, storage, purification, use, and discharge". "Infiltration" refers to increasing rainwater infiltration and reducing surface runoff through permeable pavement and green space. "Retention" refers to the use of biological retention facilities, sunken green space, etc. to retain rainwater and delay rainwater discharge. "Storage" refers to storing rainwater through facilities such as reservoirs. "Purification" refers to the natural purification of rainwater through vegetation, soil, etc. "Use" refers to the rational use of rainwater resources, such as for greening irrigation, road washing, etc. "Drainage" refers to the safe discharge of rainwater exceeding the standard through drainage facilities.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 To Attachment Fig. 9 This application is described in further detail.

[0029] In the prior art, when the drainage channels on both sides of the permeable pavement need to be cleaned, the cover plates need to be opened one by one for cleaning, which is inefficient, and the original drainage channels directly discharge surface water into the groundwater network, which does not effectively utilize rainwater resources.

[0030] In order to fully utilize rainwater resources, the present application embodiment discloses a sponge city road structure, including a permeable pavement 11, a hydrophobic structure 12, a water storage structure 13, a green belt structure 14, a drainage structure 15 and a water use structure 16.

[0031] Specifically, the permeable pavement 11, i.e., the road surface, adopts permeable materials such as permeable asphalt concrete and permeable cement concrete. Rainwater can infiltrate into the roadbed through the road surface structure layer, reduce the surface runoff, and increase the infiltration rate. The green belt structure 14 is arranged beside the permeable pavement 11. The green belt structure 14 is designed to be concave, that is, the surface is lower than the permeable pavement 11, and can collect road surface water and pavement structure layer infiltration water. The plants in the green belt structure 14 can further reduce the rainwater runoff through absorption and transpiration, and at the same time play a role in purifying rainwater. The water storage structure 13 is arranged in the soil below the permeable pavement 11. The water storage structure 13 adopts the existing PP (polypropylene) water storage tank, which is an efficient and flexible rainwater collection and storage system. The underground PP water storage tank is mainly composed of a plurality of PP rainwater slow release monomers. These monomer modules are made of injection molding materials. The PP water storage module can be customized in different shapes and sizes according to actual needs. By combining modules of different numbers and shapes, water tanks of various volumes and shapes can be flexibly constructed. The module has a large amount of water storage space inside, and at the same time has a high compressive strength and can withstand a certain ground load. The drainage structure 15 is a reinforced concrete pipe structure connected to the underground water network and is arranged in the soil. The drainage structure 15 is connected to the water storage structure 13 through an overflow pipe. After the water storage structure 13 is full, the excess water is input into the drainage structure 15 through the overflow pipe 131 and sent into the underground water network. The water use structure 16 is a water pump structure with a protective box. The water use structure 16 is arranged on the ground surface, generally on the green belt structure 14. The water use structure 16 is connected to the water storage structure 13 through a water intake pipe, and is used to take the water stored in the water storage structure 13.

[0032] In order to increase the efficiency of cleaning the drainage channel structure. The present application has made in-depth optimization of the drain structure 12, i.e., the drainage channel structure. Specifically, the drain structure 12 is arranged on one side or both sides of the permeable pavement 11, and this embodiment takes two sides as an example. The drain structure 12 is arranged in the length direction of the permeable pavement 11. The drain structure 12 is connected to the water storage structure 13 through a drain pipe 26. The excessive surface runoff on the surface of the permeable pavement 11 is digested by the drain structure 12, and the water body is purified and input into the water storage structure 13. The drain structure 12 includes a number of main control channel blocks 2 and a number of filling channel blocks 3 connected end to end in sequence. At least two filling channel blocks 3 are arranged between two adjacent main control channel blocks 2, and the several filling channel blocks 3 between the two main control channel blocks 2 are divided into two groups, and the several filling channel blocks 3 in each group are connected to one of the main control channel blocks 2 after being connected to each other. The main control channel block 2 is generally arranged along a straight line, and the filling channel block 3 can be bent. The filling channel block 3 at the excessive bending part (greater than thirty degrees) is independently arranged. By digging long strip grooves on both sides of the permeable pavement 11, the main control channel block 2 and the filling channel block 3 are laid therein to form a drain structure 12. The upper surface of the drain structure 12 is higher than the upper surface of the green belt structure 14, preventing excessive impurities such as soil and plants from entering the drain structure 12. Furthermore, the main control channel block 2 is provided with a first drain groove 21. With the gravity direction as a reference, the first drain groove 21 is penetrated at both ends in the vertical gravity direction, and the first drain groove 21 penetrates the upper wall of the main control channel block 2 upward to form an opening. Rainwater enters the first drain groove 21 through the opening and flows along the two ends to form a water flow. Similarly, the filling channel block 3 is also provided with a second drain groove 31. The second drain groove 31 penetrates the two ends of the filling channel block 3 along the length direction, and penetrates the filling channel block 3 upward to form an opening for rainwater to enter. The first drain groove 21 and the second drain groove 31 are connected to form a continuous waterway for the flow of water. The water in the second drain groove 31 and the first drain groove 21 can flow to each other, but finally converge into the first drain groove 21. In order to prevent excessive debris from entering the first drain groove 21 or the second drain groove 31, the main control channel block 2 is also rotatably connected to the upper part of the main control channel block 2, and the main control cover plate 22 can cover the opening at the upper end of the first drain groove 21. Similarly, the filling cover plate 32 that can cover the opening is rotatably connected to the filling channel block 3. A plurality of first permeable holes 221 are arranged in an array on the surface of the main control cover plate 22 and the filling cover plate 32, and water enters the first drain groove 21 and the second drain groove 31 through the first permeable holes 221. The rotating parts of the main control cover plate 22 and the filling cover plate 32 are close to the permeable pavement 11, so that the main control cover plate 22 and the filling cover plate 32 form an angle with the permeable pavement 11 after rotation, and the impurities are made to slide onto the permeable pavement 11 under the action of gravity, and then the impurities are cleaned on the permeable pavement 11 by using a vacuum cleaning device. A protective shell 24 is provided on the side of the active channel block away from the permeable pavement 11, and the protective shell 24 is a rectangular shell structure.A rotating drive assembly 4 for driving the main control cover plate 22 to rotate is provided in the protective shell 24. It is worth noting that the filling channel block 3 is not provided with a protective shell 24, which is only used to ensure the continuous flow of water. A synchronously moving linkage assembly 5 is provided between the filling cover plate 32 and the main control cover plate 22, so that the rotating drive assembly 4 drives the filling cover plate 32 to rotate while controlling the rotation of the main control cover plate 22. In order to make the water flowing into the water storage structure 13 from the first drain groove 21 cleaner and avoid corruption in the water storage structure 13. A filter assembly 6 is also provided between the drain pipe 26 and the water storage structure 13, and the filter assembly 6 is provided in the protective shell 24 for easy installation. A plurality of flushing holes 71 are provided at one end of the main control cover plate 22 and the filling cover plate 32 away from the permeable pavement 11. When the main control cover plate 22 and the filling cover plate 32 are rotated to open, water flows out through the flushing holes 71 to flush the surface of the main control cover plate 22 and the filling cover plate 32, so that impurities can slide onto the permeable pavement 11 more easily. The main control cover plate 22 is provided with a first channel 72 connected to a plurality of flushing holes 71 thereon. The filling cover plate 32 is also provided with a second channel 73 connected to a plurality of flushing holes 71 thereon. The first channel 72 is connected to the second channel 73. The water-using structure 16 is connected to the first channel 72 through a backwash pipe 74. The water-using structure 16 extracts water from the water storage structure 13, injects the water into the first channel 72 through the backwash pipe 74, and simultaneously flows into the second channel 73 until the water flows out of the flushing holes 71 on the main control cover plate 22 and the filling cover plate 32, thereby flushing the surfaces of the main control cover plate 22 and the filling cover plate 32. In addition, when the rainwater flow increases, the main control cover plate 22 can be rotated to open the opening of the first drain groove 21; when the rainwater flow decreases, the reset elastic member 43 restores the main control cover plate 22 to its initial state and closes the opening. While flushing the surfaces of the main control cover plate 22 and the filling cover plate 32, the water intake is increased. Afterwards, the inner filter plate 23 is continuously rotated until it reaches a suitable height to clean the intercepted impurities.

[0033] In order to further filter impurities in rainwater and prevent impurities from falling directly into the waterway after the main control cover plate 22 rotates. An inner filter plate 23 is fixedly connected to one end of the main control cover plate 22, and the inner filter plate 23 rotates coaxially with the main control cover plate 22. The protective shell 24 protrudes a number of hinge blocks 241 in the direction of the permeable pavement 11. The main control cover plate 22 is provided with a hinge groove 222 for inserting the hinge block 241. A rotating shaft 223 passes through one end of the main control cover plate 22. The rotating shaft 223 passes through the main control cover plate 22 and the hinge block 241, thereby forming a relative rotation between the main control cover plate 22 and the hinge block 241. The cross-section of the first drain groove 21 is a fan-shaped structure. The inner filter plate 23 is inside the first drain groove 21 and extends along the radial direction of the first drain groove 21 to abut the inner wall. The inner filter plate 23 is gap-matched with the first drain groove 21. The main control cover plate 22 is located outside, and a sinking groove is provided on the main control channel block 2 to allow the main control cover plate 22 to sink into the extension surface of the upper surface of the main control channel block 2. In order to prevent the water flow from quickly entering the first drain groove 21, causing water flow turbulence and affecting water inflow. The main control cover plate 22 and the inner filter plate 23 are set at an angle, and the angle is preferably between forty-five and ninety degrees. A plurality of second permeable holes 231 are provided in an array on the surface of the inner filter plate 23. A hydrophobic layer 25 is provided on one side of the main control channel block 2 close to the permeable pavement 11. The hydrophobic layer 25 is a rectangular structure, and the hydrophobic layer 25 is connected to the first drain groove 21. The surface runoff water passes through the main control cover plate 22 and enters the first drain groove 21, and after passing through the inner filter plate 23, it flows out of the first drain groove 21 and enters the hydrophobic layer 25. The inner wall at the bottom of the hydrophobic layer 25 shrinks and is connected to the drain pipe 26. The water passes through the hydrophobic layer 25 and flows down to the hydrophobic pipe 26 to enter the next process.

[0034] Similarly, in order to prevent impurities from entering the second hydrophobic groove 31, an inner filter plate 23 can also be provided in the second hydrophobic groove 31. The second hydrophobic groove 31 has the same shape as the first hydrophobic groove 21. However, the second hydrophobic groove 31 is not provided with a hydrophobic layer 25. The second hydrophobic groove 31 is provided with the same settling tank.

[0035] Furthermore, the rotation drive assembly 4 includes an active rod 41, a power cable 42 and a reset elastic member 43. The active rod 41 is connected to the protective shell 24 by rotation along its own axis. One end of the power cable 42 is connected to the active rod 41, and the other end passes through the outer wall of the protective shell 24 to the first hydrophobic groove 21 and is connected to the inner filter plate 23. The inner filter plate 23 is provided with a reset elastic member 43 that always makes it have a tendency to restore to the initial state. The active rod 41 is provided with a control end 411, and the control end 411 passes through the outer wall of the protective shell 24 to the outside, and a hexagonal groove 4112 is provided on the surface of the control end 411. The active rod 41 coaxially penetrates into the circular hole 4113 of the control end 411, and a slide groove 4111 is provided on the inner wall of the control end 411 along the length direction, and the active rod 41 is provided with a slider 412 that can slide in the slide groove 4111. The protection shell 24 is provided with a screw hole 242 for the control terminal 411 to rotate, and the control terminal 411 is threadedly matched with the screw hole 242 .

[0036] Furthermore, the linkage assembly 5 includes a linkage sleeve 51 and a linkage rod 52. At least two linkage sleeves 51 are provided on the inner wall of the main control cover plate 22, and the linkage rod 52 passes through a plurality of linkage sleeves 51. At least two linkage sleeves 51 and a linkage rod 52 are also provided on the inner wall of the filling cover plate 32. The ends of two adjacent linkage rods 52 are detachably connected. A connecting groove 521 is provided at the end of the linkage rod 52. A connecting column 53 is interference-fitted in the connecting groove 521, and the connecting column 53 can pass through the connecting groove 521 to the adjacent connecting groove 521.

[0037] Furthermore, the filter assembly 6 includes a basic drum 61 and a filter element 62. In other embodiments, the basic drum 61 can be fixedly connected to the protective shell 24. The drain pipe 26 is connected to the basic drum 61. The filter element 62 is arranged in the basic drum 61, and the water in the drain pipe 26 enters the water storage structure 13 after passing through the filter element 62, thereby filtering the water body to ensure the cleanliness of the water body. The drain pipe 26 includes a transition section 261 and a conveying section 262. One end of the transition section 261 can be connected to the inside of the basic drum 61, and the other end is connected to the first drain tank 21. One end of the conveying section 262 can be connected to the basic drum 61, and the other end is connected to the water storage structure 13.

[0038] Since the water storage structure 13 stores water for a long time, the tiny substances in the water body are easy to precipitate after long-term use. When the water structure 16 extracts and sends it into the first channel 72, in order to avoid blocking the first channel 72, the water body needs to be filtered twice to ensure the cleanliness of the water body. Further, a support cylinder 243 is provided at the bottom of the protective shell 24, and the basic rotating cylinder 61 is rotatably connected to the support cylinder 243.
