[0038] The implementation principle of the water storage system for municipal sponge city construction is that rainwater falls on the main road and flows to the drainage supply on both sides of the road. When the rainwater falls on the bottom wall of the drainage ditch 3, it is preliminarily filtered through the drainage cover 111 to prevent large volumes from entering the drainage ditch 3, and is further filtered through the drainage holes 4 on the drainage net 112. Small-volume sundries such as garbage fall on the drainage net 112 to prevent sundries from accumulating in the drainage ditch 3. Rainwater can smoothly flow from the bottom wall of the drainage ditch 3 into the water storage assembly 2 through the water pipe. The water storage system for municipal sponge city construction prevents garbage from blocking the drainage pipe through the preliminary filtration of the drainage cover 111 and the further filtration of the drainage net 112. Since the diameter of the water-permeable hole 5 is 9-11 mm, the diameter of the water-permeable hole 5 is relatively small, so that rainwater can pass through with the largest possible flow rate, and garbage is filtered onto the drainage net 112 for subsequent processing. Then, rainwater smoothly flows into the water storage assembly 2, ensuring smooth drainage of the road and making the city have better drainage capacity.
