[0001] This utility model relates to the field of municipal engineering technology, specifically to a sponge building structure for municipal engineering. Background Technology

[0002] Sponge building structures in municipal engineering enhance a city's ability to infiltrate, retain, store, and purify rainwater by simulating a natural water cycle system. Sponge structures can also reduce the urban heat island effect, improve the microclimate environment, and enhance the self-purification capacity of water bodies through ecological restoration, thereby strengthening the city's resilience against floods and disasters and promoting sustainable development.

[0003] For example, Chinese Patent (Announcement No.: CN217923967U) discloses a sponge building structure for municipal engineering, including a foundation. Multiple installation grooves are formed on the upper surface of the foundation, and each of the installation grooves contains a collection mechanism. The collection mechanism includes a collection box, which is fixedly connected to the bottom inner wall of the installation groove. A collection trough is formed on the upper surface of the collection box, and multiple through-holes are formed on the upper surface of the collection trough. Drainage components are provided on both sides of the collection box, and each drainage component includes multiple connecting pipes. One end of each connecting pipe is connected to a pipe on one side of the collection box. This utility model, by incorporating a collection mechanism, improves the drainage effect of urban roads. During rainy weather, rainwater flows through a waterproof asphalt layer onto the installation plate, then flows through the first drainage hole to the collection trough, and finally flows into the collection box through the second drainage hole within the collection trough, thus improving the efficiency of the device itself.

[0004] However, the structure has poor water storage effect. The device only has a blocking effect and cannot store a certain amount of rainwater. It cannot directly use the stored rainwater to water green belts, etc., and cannot reduce water costs.

Two primary moving slots are formed on the inner side of each stabilizing plate. Primary moving blocks extending into the two primary moving slots are fixed on both the left and right sides of each primary moving plate.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figure 1. A sponge building structure for municipal engineering in this embodiment includes a surface layer 1, a buffer layer 2 at the bottom of the surface layer 1 to buffer the impact on the surface layer 1, a water storage layer 3 at the bottom of the buffer layer 2 to effectively store rainwater for subsequent use, and a base layer 4 at the bottom of the water storage layer 3 to ensure overall stability.

[0025] It is understandable that the surface layer 1 includes a fine sand layer 102 laid on top of the buffer layer 2, and a water-conducting layer 101 laid on top of the fine sand layer 102. The fine sand layer 102 can ensure the smooth flow of water, and at the same time, the fine sand layer 102 can play a certain role in blocking water flow. The water-conducting layer 101 is a permeable brick. The core advantage of permeable bricks is that they allow rainwater to quickly infiltrate through their porous structure, while also having high strength, freeze-thaw resistance and anti-slip properties.

[0026] In addition, the buffer layer 2 includes a burial layer 201, with wire mesh 202 fixed at both the top and bottom. The upper wire mesh 202 is used to block the fine sand layer 102. Multiple water pipes 203 are embedded inside the burial layer 201, penetrating it. These water pipes 203 are mainly for situations with excessive rainfall, ensuring smooth drainage and preventing rainwater from accumulating in the buffer layer 2 for extended periods. Each water pipe 203 has wire mesh 202 at both the top and bottom. Fixed to the wire mesh 202, the two wire meshes 202 can act as a barrier to reduce the loss of silt or soil. The top of the upper wire mesh 202 is fixed with multiple arc-shaped blocks 204, which mainly serve as guides. The multiple arc-shaped blocks 204 and multiple water pipes 203 are arranged alternately. When rainwater flows over the arc-shaped blocks 204, it can flow smoothly into the water pipes 203 due to gravity. The upper wire mesh 202 is in contact with the fine sand layer 102.

[0027] In this embodiment, the two wire meshes 202 can effectively support the buffer layer 2 as a whole, and also serve as a barrier. Finally, the water storage layer 3 effectively stores the rainwater for subsequent use.

[0028] Please refer to Figures 1 to 4 again. In order to improve the water storage effect, the water storage layer 3 in this embodiment includes a filling layer 301. A water storage tank 302 is fixed on the inner side of the filling layer 301. The water storage tank 302 is used to store rainwater. Two moisture-retaining components 303 are provided on the top of the water storage tank 302. A top support component 304 is provided on the bottom of the water storage tank 302. The top support component 304 can improve the water absorption effect of the water suction pipe 305. A water suction pipe 305 that penetrates the buffer layer 2 and extends into the surface layer 1 is fixed on the top wall of the water storage tank 302.

[0029] Understandably, the top of the filling layer 301 is attached to the bottom of the wire mesh 202 below. The filling layer 301 is made of coarse stone blocks, which have good permeability and good support. The burial layer 201 is made of permeable concrete, which is a functional building material with a porous honeycomb structure. It has good permeability and good frost resistance. The top of the water storage tank 302 is provided with multiple water holes, which facilitate the smooth flow of rainwater into the water storage tank 302.

[0030] It should be further explained that the water storage tank 302 has through holes on both its left and right sides, flush with the inner top wall of the water storage tank 302. When the rainwater in the water storage tank 302 exceeds the height of the through holes, it will flow out through the through holes. Each moisture-retaining component 303 includes a stabilizing plate 3031 fixed to the inner top wall of the water storage tank 302. A primary moving plate 3032 is movably connected to the inner side of each stabilizing plate 3031. Two primary moving slots are opened on the inner side of each stabilizing plate 3031. Primary moving blocks extending into the two primary moving slots are fixed on the left and right sides of each primary moving plate 3032. The inner side of each primary moving plate 3032... Each primary moving plate 3032 is movably connected to a secondary moving plate 3033. Each primary moving plate 3032 has two secondary moving slots on its inner side. Each secondary moving plate 3033 has secondary moving blocks fixed on its left and right sides, extending into the two secondary moving slots respectively. This structure ensures that the primary moving plate 3032 will not completely detach from the stabilizing plate 3031, and at the same time ensures that the secondary moving plate 3033 will not completely detach from the primary moving plate 3032. Each primary moving plate 3032 and secondary moving plate 3033 has an air chamber fixed on its outer side. Under the buoyancy of water, the air chamber can drive the primary moving plate 3032 and secondary moving plate 3033 to move upward.

[0031] In addition, the top support assembly 304 includes a waterproof rubber 3041 fixed to the inner bottom wall of the water storage tank 302. The waterproof rubber 3041 has good waterproof properties and high toughness. A top support plate 3042 is fixed to the inner top wall of the waterproof rubber 3041. Multiple support springs 3043 are fixed to the bottom of the top support plate 3042. When there is too much rainwater, the water storage effect of the water storage tank 302 can be improved by compressing the support springs 3043. When there is less rainwater, it can promote the flow of water to the outside, so that the water suction pipe 305 can suck out the water. The bottom of the multiple support springs 3043 is fixed to the inner bottom wall of the water storage tank 302. Two circular grooves are opened on the top of the water guiding layer 101. Two water suction pipes 305 extend into the two circular grooves respectively. A protective cover 5 is threadedly connected to the outer surface of each water suction pipe 305 and located in the circular groove. The protective cover 5 is used to protect the water suction pipe 305.

[0032] In addition, the base layer 4 includes a stabilizing layer 401 fixed to the bottom of the filling layer 301. Two drainage pipes 402 flush with the top of the stabilizing layer 401 are embedded on the inner side of the stabilizing layer 401. The bottom of the drainage pipes 402 is fixedly connected to a sewer pipe, and excess rainwater is discharged into the sewer pipe through the drainage pipes 402.

[0033] In this embodiment, the top of the protective cover 5 is flush with the top of the surface layer 1, and the top of the water suction pipe 305 is located inside the protective cover 5. The protective cover 5 can effectively protect the water suction pipe 305.

[0034] It is understandable that by working together with the moisturizing component 303 and the top support component 304, the water storage effect of the water tank 302 can be improved, and the moisturizing component 303 can reduce water loss when the water is low.

[0035] The working principle of the above embodiments is as follows:

[0036] (1) When rain comes, rainwater will seep through the surface layer 1 to the buffer layer 2. When the amount of rain is small, the rainwater can seep through the burial layer 201 and the water pipe 203 into the water storage layer 3. When the rain is heavy, the water mainly flows through the water pipe 203 to the water storage tank 302. When there is a lot of water, the support spring 3043 will feel the pressure and compress, thus reserving more space for rainwater and further improving the water storage capacity. When the rain is too heavy, the rainwater will cause the first-stage moving plate 3032 and the second-stage moving plate 3033 to float up. The rainwater in the upper part of the water storage tank 302 can flow out to the stabilizing layer 401 and flow through the drainage pipe 402 into the sewer pipe.

[0037] (2) When needed, simply unscrew the protective cover 5 and connect the water inlet of the pump to the suction pipe 305. This will allow the water in the water storage tank 302 to be pumped out for watering urban green belts, etc. At the same time, as the water in the water storage tank 302 is gradually pumped out, the pressure decreases due to the less water above the top support component 304. Under the action of the support spring 3043, the waterproof rubber 3041 will be pushed upward, further promoting the water to flow to the outer periphery, making it easier for the suction pipe 305 to absorb water.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] 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.
