[0011] Compared with the prior art, this utility model has the following advantages:

[0012] (1) This utility model integrates the filter layer, permeable layer and pavement layer into a module by using multiple modular boxes that can be spliced ​​together, thereby avoiding soil and water loss in the filter layer and permeable layer and improving the overall stability of the pavement.

[0013] (2) By adding road bricks, multiple water-stop strips and multiple water-permeable holes, the rainwater flows on the road bricks.

[0019] 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.

[0020] refer to Figures 1-2 As shown, the present invention provides a modular rainwater retention and purification device for mountainous urban slopes, comprising: a slope foundation 1, on which multiple modular module boxes 5 are arranged in a dot matrix pattern, and each module box 5 is provided with a water storage structure, a filter layer 9, a permeable layer 10 and a road surface layer from bottom to top.

[0021] Combination Figure 1 and Figure 3As shown, the water storage structure includes a filter plate 7 and multiple support columns 6. The filter plate 7 is located at the bottom of the filter layer 9, and the multiple support columns 6 are all supported in the module box 5. A water storage cavity 14 for storing rainwater is formed between the multiple support columns 6.

[0022] The above describes the use of the slope foundation 1 and multiple modular boxes 5 provided by this utility model. The multiple modular boxes 5 are distributed in a dot matrix on the slope foundation 1. Each modular box 5 is provided with a water storage structure, a filter layer 9 and a permeable layer 10 from bottom to top, which makes it easy to divide the entire road surface into multiple small modular sections, which facilitates later management and avoids soil erosion.

[0023] Furthermore, in order to facilitate the discharge of accumulated water resources, refer to Figure 1 As shown, a drainage pipe 2 for drainage is pre-embedded in the slope foundation 1. Multiple branch pipes 3 are provided on the drainage pipe 2. Each module box 5 has a through hole 4 at the top that connects the water storage chamber 14 and the branch pipe 3. The multiple branch pipes 3 facilitate the centralized input of water resources in each water storage chamber 14 into the drainage pipe 2, and the drainage pipe 2 facilitates the collection and utilization of water resources.

[0024] Furthermore, to facilitate water flow between adjacent module boxes 5, refer to Figures 1-2 As shown, permeable areas 8 are provided around the top of the module box 5. These permeable areas 8 facilitate the flow of water between the module boxes 5.

[0025] Furthermore, to improve the stability of the direct connection between adjacent module boxes 5, refer to Figure 1 As shown, multiple connecting bolts 15 are provided between each pair of adjacent module boxes 5 for connection. After the module box 5 is buried in the slope foundation 1, the adjacent module boxes 5 are connected by multiple connecting bolts 15 to prevent local settlement of the module boxes 5.

[0026] In this utility model, combined with Figure 1 and Figure 4 As shown, the pavement layer of this embodiment includes pavement bricks 13 and multiple waterstop strips 12 disposed on the top surface of pavement bricks 13. The multiple waterstop strips 12 are distributed at equal intervals along the runoff direction.

[0027] As described above, when using the road surface layer provided by this utility model, the road surface layer is laid by multiple road bricks 13. When rainwater flows on the road surface, the water-stop strip 12 blocks the flow of water and reduces the flow velocity of the water.

[0028] Furthermore, in order to facilitate the retention of water resources on the road surface, refer to Figure 1 and Figure 4As shown, the pavement layer includes pavement bricks 13, with multiple permeable holes 11 penetrating the pavement bricks 13. The permeable holes 11 are respectively arranged between two adjacent waterstop strips 12. The permeable holes 11 facilitate the flow of rainwater between adjacent waterstop strips 12 from the pavement into the permeable layer 10, thereby facilitating the retention of water resources on the pavement and preventing water loss.

[0029] 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, the scope of which is defined by the appended claims and their equivalents.
