Sponge city water storage structure

Abstract

The invention relates to a sponge city water storage structure. The sponge city water storage structure comprises a water storage pool and further comprises a water pumping device and a rotating device. The water pumping device comprises a first water pump, a first water pumping pipe and a first water drainage pipe, wherein the first water pump is arranged above a green plant planting layer, one end of the first water pumping pipe is connected with a water inlet of the first water pump, the other end of the first water pumping pipe penetrates through the green plant planting layer and a filtering plate and is located in the water storage poor, and one end of the first water drainage pipe is connected with a water outlet of the first water pump. The rotating device comprises a motor, a rotating disc and an irrigating pipe, wherein the rotating disc is arranged in a hollow state, one end of the rotating disc is connected with the motor, the other end of the rotating disc is connected with the first water drainage pipe in a rotating mode, the irrigating pipe is arranged on the side wall of the rotating disc and communicates with the rotating disc, the irrigating pipe is located abovethe green plant planting layer and provided with an irrigating port, and the irrigating port faces the green plant planting layer. The water storage pool can supply water for the green plant plantinglayer above the water storage pool and can also carry out irrigation from the part above the green plant planting layer, and the water supply range is large.

Description

technical field [0001] The invention relates to the technical field of sponge city water storage engineering, in particular to a sponge city water storage structure. Background technique [0002] At present, in the rainy season, surface rainfall can easily form surface runoff, causing urban waterlogging and affecting production and life. Especially in the old urban areas, water storage and drainage systems are often imperfect, and waterlogging is particularly prone to occur. Sponge cities are one of the ways to control waterlogging. Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". [0003] The Chinese patent with the notification number CN109372077A discloses a water storage structure with anti-overflow function for sponge cities. The water storage structure with anti-overf...
