Embodiment Construction
[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0040] Present embodiment: a kind of sponge city rainwater garden, as Figure 1 to Figure 3 As shown, the concave pool 1 is included, and the concave pool 1 is sunken to a predetermined depth underground. Looking down from a height, the concave pool 1 is circular, and a protective wallboard 2 is attached on the side wall of the concave pool 1. , The top of the protective wall panel 2 is provided with a bent portion, so that the bent portion can be attached to the top edge of the concave pool 1 .
[0041] A flow limiting device is provided at the edge of the concave pool 1, the flow limiting device can filter large particles of debris, so that the debris is blocked outside the concave pool 1, and a water receiving tank is installed on the outside of the protective wall panel 2 3. The number of water receiving tanks 3 can be multiple or single, depending on th...

The invention relates to a sponge city rainwater garden and a construction method, and belongs to the technical field of rainwater gardens. According to key points of the technical scheme, a sunken pool sinking downwards, a protective wallboard attached to the side wall of the sunken pool and the edge of the sunken pool, a flow limiting device which is arranged at the edge of the sunken pool and used for limiting the passage of debris, a water receiving tank which is detachably installed on the outer side of the protective wallboard and used for receiving sewage, and a filtering device which is arranged in the water receiving tank and used for filtering water are included. When the rainwater garden is used, the debris flowing into the sunken pool can be blocked and filtered, the situationof the debris entering the sunken pool is reduced, thus the situation of the debris blocking the sunken pool can be reduced, and adverse effects on the rainwater garden is lowered.
Description
technical field [0001] The invention relates to the technical field of rain gardens, in particular to a sponge city rain garden and a construction method. Background technique [0002] Rain gardens are not only an important way to replenish groundwater in nature, but also the main source of production water in modern urban life. During the construction of sponge cities, some sunken pools are often artificially excavated to guide rainwater from the ground or other places, making Rainwater collects here. [0003] At present, the rain garden generally includes a gravel cushion, a non-woven geotextile filter layer, a fine sand sediment layer and a fine sand cushion from bottom to top. At the same time, various green plants will be planted on the surrounding ground. To play a role in stabilizing water and soil. [0004] However, during the actual use of the rain garden, especially when it rains heavily, some light debris on the ground or sand, stones and solid debris around the...
