[0028] Embodiment 1

[0029] As Figures 1 to 2 shown, the present utility model provides a technical solution:

[0030] An old community sponge water regulation structure, which at least includes but is not limited to a first water permeable part 1, a second water permeable part 2, a water regulation part 3 and a conveying part 4; the first water permeable part 1 is arranged on the water regulation part 3, the second water permeable part 2 is arranged close to the first water permeable part 1, the second water permeable part 2 is in contact with and connected to at least part of the area of the first water permeable part 1, and the conveying part 4 is arranged at the lower side position of the water regulation part 3 and is in contact with the water regulation part 3.

[0031] Based on the above structure, the first water permeable part 1 and the second water permeable part 2 can guide part of the surface water body, and finally store it in the water regulation part 3 through layer-by-layer infiltration. The water regulation part 3 stores part of the water body and decelerates the passing water body to reduce the confluence speed of the water body, avoiding the situation of exceeding the maximum water storage level in a short time. The conveying part 4 can convey the water body passing through the water regulation part 3 outward.

[0032] As an example, an observation part 5 can also be arranged on the water regulation part 3. The first water permeable part 1 is symmetrically arranged on both sides of the observation part 5. The observation part 5 can be made of a transparent material, and the situation of the water regulation part 3 can be directly observed through the observation part 5.

[0033] As an example, the observation part 5 can be a U-shaped structure. The lower part of the observation part 5 is connected to the water regulation part 3 in a penetrating manner, and the water body in the water regulation part 3 can be stored in the observation part 5.

[0034] Based on the above structure, the water diversion part 3 can slow down the water body. When the water flow converging from the first water permeable part 1 and the second water permeable part 2 is greater than the water flow it outputs, the excess water will be stored in the cavity structure of the observation part 5. On the one hand, it increases the water diversion volume of the water diversion part 3, and on the other hand, it also facilitates the adjustment of the subsequent water outlet speed.

[0035] As an example, the first water permeable part 1 may include an ecological layer 11, a gabion mesh layer 12, a concrete cushion layer 13, and a gravel cushion layer 14; the ecological layer 11 is arranged adjacent to the observation part 5, and the gabion mesh layer 12, the concrete cushion layer 13, and the gravel cushion layer 14 are arranged in sequence from top to bottom; the bottom of the ecological layer 11 is in contact with the concrete cushion layer 13, and the side of the ecological layer 11 is in contact with the gabion mesh layer 12; vegetation can be planted in the ecological layer 11.

[0036] Based on the above structure, when it rains, on the one hand, the rainwater seeps downward through the ecological layer 11, and on the other hand, it seeps downward through the gabion mesh layer 12, the concrete cushion layer 13, and the gravel cushion layer 14 in sequence. The ecological layer 11 stores and utilizes part of the water body, and the other water body is filtered downward and then conveyed to the water diversion part 3.

[0037] As an example, the concrete cushion layer 13 can be C20 concrete with a thickness of 100 mm, and the thickness of the gravel cushion layer 14 is 150 mm. The gabion mesh layer 12 includes a plurality of gabion meshes. The gabion mesh is an ecological grid structure, which is made of low-carbon steel wires and galvanized steel wires with high corrosion resistance, high strength, and high elongation. The whole network has the characteristics of high strength, good toughness, good corrosion resistance, and long service life. The product is simple to manufacture and has a low cost.

[0038] As an example, the second water permeable part 2 may include a colored strong and solid permeable concrete layer 21, a permeable concrete layer 22, a water permeable geotextile layer 23, a gravel layer 24, and a composite geotextile layer 25; the colored strong and solid permeable concrete layer 21 is arranged at the topmost layer, and the colored strong and solid permeable concrete layer 21 is flush with the ecological layer 11 and the gabion mesh layer 12; the permeable concrete layer 22 is arranged on the lower side of the colored strong and solid permeable concrete layer 21, the water permeable geotextile layer 23 is arranged on the lower side of the permeable concrete layer 22, the gravel layer 24 is arranged on the lower side of the water permeable geotextile layer 23, the composite geotextile layer 25 is arranged at the position below the gravel layer 24, and the composite geotextile layer 25 is arranged on the original roadbed;

[0039] The horizontal position of the lowest part of the gravel layer 24 is not lower than the horizontal position of the lowest part of the gravel cushion layer 14, and the gravel layer 24 is adjacent to the gravel cushion layer 14.

[0040] Based on the above structure, the second water-permeable part 2 is the main water-permeable component, and most of the layers on it are water-permeable mechanisms. When it rains, water bodies pass through the colored strong-solid water-permeable concrete layer 21, the water-permeable concrete layer 22, and the water-permeable geotextile layer 23 in sequence to reach the gravel layer 24. Since the lower side of the gravel layer 24 is the composite geotextile layer 25, the water bodies cannot drain downward any further, so they will be temporarily stored in the gravel layer 24. Since the gravel layer 24 is adjacent to the gravel cushion layer 14, the water bodies will flow to the gravel cushion layer 14 in a small flow rate and finally converge into the water regulation part 3.

[0041] As an example, the colored strong-solid water-permeable concrete layer 21 is a 50-mm-thick C20 colored concrete; the water-permeable concrete layer 22 is a 190-mm-thick C20 water-permeable concrete; the gravel layer 24 is 200 mm thick.

[0042] As an example, the water regulation part 3 can include a high-density sponge layer 31 and a fluffy support layer 32; the fluffy support layer 32 is arranged above the high-density sponge layer 31; the fluffy support layer 32 is made of polypropylene material and has an overall grid-like through-hole structure;

[0043] Based on the above structure, the water bodies converging from the first water-permeable part 1 and the second water-permeable part 2 will first pass through the grid-like fluffy support layer 32. The internal grid structure will hinder the flow rate of the water bodies to a certain extent and reduce the flow rate of the water bodies. At the same time, the water bodies can also flow freely in the fluffy support layer 32. Finally, a part of the water bodies is absorbed by the high-density sponge layer 31. The high-density sponge layer 31 after absorbing the water bodies will further hinder the flow rate of the water bodies, enabling it to transmit the water bodies to the conveying part 4 in a low flow rate. The corresponding water bodies can converge in the observation part 5. Through this solution, the water bodies formed by rainfall can be effectively regulated, reducing the pressure on urban water storage, and the stored water bodies can be released slowly to ensure the safety of urban pipeline water storage and prevent it from exceeding the maximum limit.

[0044] As an example, the conveying part 4 can include a water-permeable geotextile layer 23, a blind pipe layer 41, and a composite geotextile layer 25; the water-permeable geotextile layer 23 is arranged below the high-density sponge layer 31, the composite geotextile layer 25 is arranged below the blind pipe layer 41, and the blind pipe layer 41 is arranged in the area between the water-permeable geotextile layer 23 and the composite geotextile layer 25.

[0045] Based on the above structure, the high-density sponge can also gradually release the water bodies downward after absorbing water, and flow quickly into the blind pipes through the water-permeable geotextile, and finally drain out through the blind pipes. The lower side of the composite geotextile is the original base layer. The composite geotextile layer 25 can block the water bodies to prevent them from being further conveyed downward.

[0046] Through this solution, during rainfall, it is possible to temporarily store the rainwater runoff at the peak flow moment, and discharge the water body after the maximum flow rate drops. At the same time, part of the water body in the high-density sponge layer 31 can also supply water to the ecological layer 11 through evaporation during non-rainy seasons. On the one hand, it can regulate the rainwater peak flow, and on the other hand, it can realize the recycling of rainwater.

[0047] Embodiment 2

[0048] As Figure 3 shown, a sponge greening water regulation and utilization system includes a multi-stage water regulation structure, multi-stage water storage tanks 6, a first pipeline 7, a second pipeline 8, and a circulation pump 9. Each stage of the water regulation structure forms a circulation loop with the adjacent water storage tank through the first pipeline 7 and the second pipeline 8. An overflow pipe 10 is provided between adjacent water storage tanks. An overflow plate 110 is also provided on each stage of the water storage tank. The height position of the overflow plate 110 matches the overflow. From the first-stage water storage tank to the last-stage water storage tank, the height of the overflow plate 110 decreases in sequence. The last-stage water storage tank is connected to the urban underground pipe network system. The circulation pump 9 is respectively arranged in the first pipeline 7 and the second pipeline 8.

[0049] Based on the above structure, the water body in the water regulation structure is transported to the water storage tank 6 through the first pipeline 7. The water body in the water storage tank 6 is discharged into the water regulation structure through the second pipeline 8 as needed. Since the fixed water body in the water storage tank 6 is usually stagnant water, and stagnant water is usually more likely to breed bacteria, the water regulation structure and the water storage tank 6 are connected into a circulation structure through the first pipeline 7 and the second pipeline 8, and the circulation pump 9 is regularly turned on. On the one hand, it can prevent the water body from flowing, and on the other hand, it can reverse-fill the high-density sponge layer 31 to enable it to continuously supply water to the ecological layer 11. In another solution, since the space in old residential areas is relatively small and inconvenient for construction, multiple small water storage tanks are dispersed and connected through overflow pipes between adjacent water storage tanks. On the one hand, it can ensure that there is a certain amount of water body in each stage of the water storage tank to supply water to the vegetation and realize resource utilization. On the other hand, the multi-stage structure is also convenient for later maintenance.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
