[0003] After searching, a sponge city sidewalk modular facility water storage device with patent publication number CN220665851U was found. The solution includes a water tank arranged directly below the sponge city sidewalk. A dredging structure is arranged inside the water tank. A plurality of water storage holes for rainwater diversion are opened on the upper surface of the water tank. A dredging pipe for silt and scale is arranged at the lower part of the water tank and on the outside of the water tank.
