Description

Technical Field

[0001] This utility model relates to the field of green belts, specifically to a municipal sunken green belt. Background Technology

[0002] Sunken green belts are green space designs that are lower than the surrounding ground level, primarily used to collect and store rainwater, thereby reducing runoff discharge. They have multiple functions and benefits, not only increasing the city's green coverage but also providing more open space, improving the urban landscape and residents' quality of life. Through proper design and construction, they can effectively collect, store, and purify rainwater, playing a vital role in alleviating urban flooding and improving the urban microclimate and ecological environment. However, when rainwater flows into sunken green belts from the road surface, it often carries some road debris, leading to garbage accumulation and blockages over time. Furthermore, during heavy rains, the inflow of water exceeds the capacity of the sunken green belt, causing overflow. Therefore, this application proposes a municipal sunken green belt design.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model provides, for example Figure 1-5 The illustrated municipal sunken green belt includes a road foundation 1 and a green belt body 2. The green belt body 2 is located on the roadside of the road foundation 1 and is U-shaped, with its right side contacting the roadside of the road foundation 1. A second partition 4 is fixedly installed at the bottom right side of the inner wall of the green belt body 2. A fixing plate 5 is fixedly installed on the right side of the second partition 4. A filter plate 6 is installed between the top of the fixing plate 5 and the top right side of the green belt body 2. Several permeation holes 7 are evenly distributed on the filter plate 6. An inverted L-shaped first partition 3 is fixedly installed at the bottom left side of the inner wall of the green belt body 2. The horizontal part of the first partition 3 is fixedly connected to the top left side of the inner wall of the green belt body 2. A filter pipe 10 is fixedly installed at the bottom of the horizontal part of the first partition 3 for filtration. A pumping pipe 12 is installed inside the pipe 10. The top of the pumping pipe 12 extends out through the side wall of the filter pipe 10. Inside the main body 2 of the green belt and between the first partition 3 and the second partition 4, a planting soil layer 14, a filter layer 15, an impermeable layer 16 and a water storage layer 17 are distributed from top to bottom. Rainwater on the road foundation 1 enters the main body 2 of the green belt through the seepage holes 7 on the filter plate 6. The garbage flowing with the rainwater is intercepted on the filter plate 6. The rainwater entering the main body 2 of the green belt enters the water storage layer 17 through the filter holes on the second partition 4 for storage. When the amount of rainwater is large, the rainwater will reach the position of the filter pipe 10 through the filter holes on the first partition 3. After entering the filter pipe 10, the rainwater can be discharged into the drainage pipe in the urban road through the pumping pipe 12.

[0023] To facilitate the inflow and outflow of water, such as Figure 2 As shown, the lower half of the surfaces of the first partition 3 and the second partition 4 are provided with several neatly arranged water-filtering holes. In this way, rainwater flowing into the main body 2 of the green belt flows through the water-filtering holes on the first partition 3 and the second partition 4.

[0024] To facilitate the collection of rainwater from the road foundation 1, such as Figure 1 and Figure 2As shown, the right side of the road foundation 1 is set as a slope, the filter plate 6 is set in an inclined state, and the bottom of the filter plate 6 is flush with the slope on the right side of the road foundation 1. In this way, rainwater on the road foundation 1 can smoothly enter the green belt body 2 from the filter plate 6.

[0025] To prevent the filter plate 6 from shifting position arbitrarily, such as Figure 3 and Figure 5 As shown, multiple insertion holes 8 are evenly provided on the fixing plate 5. The same number of insertion rods 9 as the insertion holes 8 are evenly and fixedly installed on the bottom left side of the filter plate 6. Each insertion rod 9 is inserted into the corresponding insertion hole 8 on the fixing plate 5. In this way, the filter plate 6 can be stably placed on the top of the fixing plate 5 and the right end of the green belt body 2, thereby playing a certain role in intercepting garbage.

[0026] In order to treat the excessive water within the main body of the green belt 2, such as Figure 3 and Figure 4 As shown, an opening 13 is provided on the left side of the main body 2 of the green belt. One end of the water pumping pipe 12 extends from the opening 13 into the soil of the road foundation 1. Several filter holes 11 are evenly provided on the surface of the lower half of the filter pipe 10. The bottom end of the water pumping pipe 12 inside the filter pipe 10 is located above the filter holes 11. In this way, the filter pipe 10 can filter the water, so that the water pumping pipe 12 can drain away excess water normally.

[0027] Finally, in order to store more water, such as Figure 1 As shown, the filter layer 15 is composed of gravel, which is a common filter material with good permeability and filtration performance. The impermeable layer 16 is composed of a composite geomembrane, which is made of geotextile and geomembrane. It has high tensile and tear resistance and is suitable for municipal engineering and water conservancy projects. The water storage layer 17 is composed of ecological clay, which is a new type of inorganic water storage material with excellent water storage function. It is made by processing clay from urban construction waste into particles or plates with an internal structure similar to a honeycomb through a special process. It has the characteristics of rapid water absorption, strong water storage, water filtration and purification and uniform water release.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
