A water circulation device for sponge city landscape

Abstract

A water circulation device for sponge city landscape, including a pool, the side of the pool is an annular barrier layer, the bottom of the pool is a concrete layer, the inner center of the concrete layer has an inner cavity, the bottom of the inner cavity is connected to a vertical shaft, and there is a driving component in the inner cavity , the vertical axis is connected to the vertical pipe, the upper end of the vertical pipe is connected to the water spray tube, there is a water spray hole on the outside of the water spray tube, there is a nozzle on the outside of the water spray hole, there is an annular planting belt on the outside of the pool, and plants are planted on the planting slope of the annular planting belt, There is an annular water storage cavity inside the annular enclosure layer, and a water supply pipe is provided at the lower part of the annular enclosure layer, and the water supply pipe is connected with a water supply device. The upper part of the annular enclosure layer has a hole and an overflow pipe is arranged in the hole. In rainy days, the present invention uses the annular water storage cavity and the pool together to achieve the effect of water storage and drainage. When used in dry weather, the plants are distributed around the annular pool through the setting of the annular planting belt, so that the annular water spray canister can All the plants play a watering role, thereby ensuring the water source required for the normal growth of the plants.

Description

technical field [0001] The invention belongs to the field of sponge city landscape devices, in particular to a water circulation device for sponge city landscapes. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge, and has good elasticity in adapting to environmental changes and dealing with natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development rainwater system construction". When it rains, water is absorbed, stored, infiltrated, purified, and the stored water is released and utilized when needed. It can be seen everywhere in parks and green spots in the city. Parks and Greening points can beautify the city and improve the air quality of the city, but the current green belts have poor water seepage and water storage capacity in response to rainy days, which will cause surface runoff, making it i...

[0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge, and has good elasticity in adapting to environmental changes and dealing with natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development rainwater system construction". When it rains, water is absorbed, stored, infiltrated, purified, and the stored water is released and utilized when needed. It can be seen everywhere in parks and green spots in the city. Parks and Greening points can beautify the city and improve the air quality of the city, but the current green belts have poor water seepage and water storage capacity in response to rainy days, which will cause surface runoff, making it impossible for people to carry out activities around the green belt for a period of time. In addition, in dry weather, manual watering is required at regular intervals, which increases the use of manpower, and it is difficult to adjust the frequency of watering in accordance with weather changes.
