[0028] [First Embodiment]

[0029] As Figures 1-5 shown, a prefabricated bioretention grid provided by the first embodiment of the present utility model is as Figure 1 shown, which includes a bottom support plate 5 and a top support plate 6 located on its top. The bottom support plate 5 and the top support plate 6 respectively play a supporting role to prevent deformation at the bottom and top. The support column 1 is located between the two, and its two ends are respectively fixedly connected to the bottom support plate 5 and the top support plate 6. The support column 1 plays an overall supporting role to prevent the soil layer from collapsing or deforming. A water storage module 3 is arranged on the top of the bottom support plate 5 to collect and store the rainwater purified by infiltration. A water permeable hole 2 communicating with the inside of the water storage module 3 is opened on the outer edge of the support column 1. The rainwater purified by infiltration in the soil layer can enter the inside of the water storage module 3 through the water permeable hole 2. A drain pipe 4 communicating with the inside of the water storage module 3 is arranged on one side of the water storage module 3 to realize the discharge of the water body inside the water storage module 3. By adopting a support structure with support columns directly fixedly connected between the bottom support plate and the top support plate, it is convenient for people to move above this facility without occupying the activity space.

[0030] As Figure 3 shown, the support column 1 in this embodiment includes an upper solid part 11 and a lower hollow part 12. The upper solid part 11 plays a supporting role. A number of water permeable holes 2 are evenly opened on the bottom outer edge of the support column 1, and the water permeable holes 2 are communicated with the inside of the water storage module 3 through the lower hollow part 12. The lower hollow part 12 facilitates the rainwater purified by infiltration in the soil layer to enter the inside of the water storage module 3.

[0031] The prefabricated bioretention grid in this embodiment adopts a modular structure. Therefore, the drain pipe 4 can be used to connect the water storage modules 3 of adjacent bioretention grids, so as to realize the mutual circulation of the infiltrated and purified rainwater between the water storage modules 3 of adjacent bioretention grids. The drain pipe 4 located at the end of the grids of multiple modular structures is connected to the rainwater drain pipe or the soil layer, so as to drain the water in the multiple water storage modules 3 to the rainwater drain pipe or the soil layer through the drain pipe 4.

[0032] As Figure 2 shown, in this embodiment, a penetration hole 61 is formed inside the top support plate 6. When setting the aperture of the penetration hole 61, it is necessary to meet the requirements that it does not affect the infiltration of rainwater and at the same time does not affect the growth of plant roots inside it. That is, the penetration hole 61 can not only realize the infiltration of rainwater but also the growth of plant roots inside it. During construction, it can be installed on the support column 1 after the soil layer is filled inside the penetration hole 61.

[0033] As Figures 4-5 shown, in this embodiment, a covering layer 7 is arranged on the top of the top support plate 6. The covering layer 7 is made of a permeable material. By setting the covering layer 7, it is convenient to set corresponding green plants or bricks on its top according to the actual application scenarios.

[0034] As Figure 4 shown, when the prefabricated bioretention grid is applied to the green space environment, green plants B can be planted on the top of the covering layer 7. The roots of the green plants B can grow through the covering layer 7 and enter the penetration hole 61 inside the top support plate 6, thereby further improving the planting stability of the green plants. As Figure 5 shown, when the prefabricated bioretention grid is applied to the road environment, permeable bricks A can be arranged on the top of the covering layer 7. The road runoff rainwater can penetrate through the permeable bricks A and the covering layer 7 and then infiltrate into the top support plate 6. Thus, the prefabricated bioretention grid provided in this embodiment has a wide range of application scenarios and can be applicable to both the green space environment and the urban road environment, with a wide range of applications.

[0035] As Figures 4-5 shown, between the top support plate 6 and the bottom support plate 5 in this embodiment, a soil layer 8, an upper sand layer 9 and a lower sand layer 10 are filled in sequence from top to bottom, and it is satisfied that the particle size of the upper sand layer 9 is larger than that of the lower sand layer 10 to realize the step-by-step filtration process of the infiltrated rainwater, and further improve the cleanliness of the rainwater inside the water inlet and storage space 3. As a preferred method, the upper sand layer 9 can be set as a coarse sand layer. Correspondingly, the lower sand layer 10 can be set as a gravel layer or a fine sand layer with a smaller particle size.

[0036] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
