[0039] In the embodiment, the sponge city storage and drainage structure can improve the rainwater permeation effect through the setting of the water collecting module 1. The shape of the hexagonal water collecting groove 102 can improve the stability and uniformly disperse the rainwater pressure, so that the rainwater permeation path is shorter and the permeation efficiency is higher. It is suitable for areas with complex terrain or high strength bearing requirements. The primary filter screen 103 can filter foreign matters and reduce the probability of blockage of other components. The drainage holes 106 can connect the plurality of hexagonal water collecting grooves 102, improve the rainwater permeation efficiency, and further improve the storage capacity of rainwater through the setting of the water storage module 2.

The excess rainwater can be quickly discharged through the setting of the drainage module 3, reducing the probability of waterlogging.

[0040] The working principle of the above embodiment is that rainwater penetrates and stores water towards the water storage module 2 through the plurality of hexagonal water collecting tanks 102, and the impurities introduced in the rainwater can be filtered through the primary filter screen 103, reducing the probability of subsequent component blockage. When too many impurities are filtered out of the primary filter screen 103, the corresponding hexagonal water collecting tank 102 will be blocked, at which time the rainwater in the hexagonal water collecting tank 102 can be delivered to other hexagonal water collecting tanks 102 through the drainage hole 106 for penetration and storage, improving the penetration rate of rainwater. Then the staff needs to clean the primary filter screen 103 regularly, rainwater in the hexagonal water collecting tank 102 will be delivered to the uppermost water storage tank A 201 through the water delivery hole 104 and the water delivery pipe 105, and then subjected to secondary filtration through the secondary filter screen 203, after which the rainwater will flow into the water storage tank A 201 in the middle layer through the flow guide hole 204, and then continue to flow downward in the water storage tank A 201 in the middle layer through the flow guide hole 204, and finally flow into the water storage tank B 202 in the bottom layer. In this way, the two water storage tanks A 201 and the water storage tank B 202 can both store water, increasing the storage capacity, and the rainwater in the water storage tank A 201 and the water storage tank B 202 can be quickly drained through the plurality of drainage openings 301 and the connecting pipe 302, reducing the probability of waterlogging.
