[0002] Sponge city is a new generation of urban stormwater management concept, which refers to a city that can be as resilient as a sponge in adapting to environmental changes and coping with natural disasters caused by rainwater. Bioretention facilities are an important component of sponge city. They are linear, shallow, and regularly shaped sunken landscape spaces with rich landscaping plants.

[0003] Existing municipal road bioretention ponds have the following drawbacks: 1. Most of them still rely on traditional, simple structures. When there is excessive rainwater, the retention area cannot absorb the excess rainwater, which can cause rainwater to accumulate in the retention area and lead to the death of green plants; 2. Although there are rainwater drainage pipes, rainwater carries a large amount of sediment when entering the pipes, which can easily cause blockages and prevent rainwater from flowing into the pipes quickly.

[0004] To address the aforementioned issues, an innovative design was implemented based on the existing biological retention tank. Utility Model Content

[0022] 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.

[0023] 1. Please refer to Figures 1-6 This utility model provides a composite bioretention pond suitable for urban roads, including a pond body 1 set at the edge of the road with an opening at the top. Water pipes 2 are connected to both side walls of the pond body 1. A stainless steel frame 3 is detachably installed at the opening of the pond body 1. A cage 4 is installed on the lower surface of the stainless steel frame 3 and is located inside the pond body 1. A first filter layer is filled in the bottom of the inner side of the cage 4. A sand filter frame 6 is detachably installed at the upper end of the stainless steel frame 3 and extends into the cage 4. An isolation net 7 is installed at the bottom of the sand filter frame 6. A second filter layer is filled in the bottom of the inner side of the sand filter frame 6 above the isolation net 7. A planting pot 9 is set in the inner side of the sand filter frame 6. A baffle 10 is installed on the edge of the planting pot 9 to abut against the upper edge of the sand filter frame 6.

[0024] In one or more embodiments of this utility model, the opening edge of the pool body 1 is set as a stepped structure, which matches the outer edge of the stainless steel frame 3, so that the stainless steel frame 3 can be stably installed in the pool body 1, and the stepped opening can stably support the stainless steel frame 3.

[0025] The stainless steel frame 3 and the cage 4 are welded together as one piece. The first filter layer, which is a gravel layer, is filled at the bottom inside the cage 4, which improves the stability of the installation between the stainless steel frame 3 and the cage 4. The gravel layer can filter rainwater and sewage.

[0026] The edge of the sand filter frame 6 is fixed with a support block 8. The opening edge of the stainless steel frame 3 is provided with a slot 5 that matches the support block 8. When the sand filter frame 6 is placed in the upper port of the stainless steel frame 3, the support block 8 is just inserted into the slot 5. The support block 8 and the slot 5 cooperate with each other, which is conducive to the stable installation of the sand filter frame 6.

[0027] The second filter layer, which is filled at the bottom of the inner side of the sand filter frame 6, is a coarse sand layer. The coarse sand layer can intercept and filter the lost soil to avoid clogging.

[0028] Planting pots 9 are evenly distributed within the sand filter frame 6. The width of the planting pots 9 is the same as the opening width of the sand filter frame 6. The baffle 10 is attached to the upper surface of the opening edge of the sand filter frame 6. The baffle 10 rests against the opening edge of the sand filter frame 6, which can effectively support the planting pots 9 and prevent the planting pots 9 from sinking deep into the sand filter frame 6.

[0029] The planting pot 9 has a permeable soil layer inside, on which plants are planted. The bottom of the planting pot 9 has windows 11 evenly spaced. The permeable soil layer and plants can initially filter sewage and rainwater. Excess water can pass through the windows 11 to drain away, preventing the retention area from being unable to absorb too much rainwater and causing the green plants to die.

[0030] according to Figures 1-6 As shown, in use, first place the stainless steel frame 3 along with the cage 4 into the pool 1. The stainless steel frame 3 will be secured at the opening of the pool 1. Then, fill the cage 4 with a gravel layer of a certain thickness. Next, place the sand filter frame 6 into the cage 4, so that the support blocks 8 on the edge of the sand filter frame 6 are engaged in the grooves 5 on the edge of the stainless steel frame 3. Then, lay a layer of coarse sand on the bottom of the sand filter frame 6. Next, place the planting pot 9 into the sand filter frame 6, and lay a layer of permeable soil in the planting pot 9. Finally, plant the vegetation and plants in the planting pot 9. Inside, the plants and vegetation in the planting pot 9, as well as the infiltration soil layer, can initially infiltrate and purify rainwater and sewage. The rainwater that has completed the initial infiltration filtration can continue to flow downwards, passing through the window 11 into the sand filter frame 6 and the cage 4, preventing rainwater from accumulating in the retention zone and causing the death of green plants. The rainwater and sewage entering the sand filter frame 6 and the cage 4 can be further filtered through the coarse sand layer and gravel layer before flowing into the water pipe 2, preventing rainwater from carrying a large amount of accumulated material when entering the pipe and preventing pipe blockage.

[0031] 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.
