Water storage plant wall for sponge city

Abstract

The invention discloses a water storage plant wall for a sponge city. The water storage plant wall for the sponge city comprises a plant wall body and water channel; the water channels are arranged onthe two sides of a road; one end, near the plant wall body, of each water channel communicates with a water inlet pipe; a water discharging pipe is arranged at the bottom of the water inlet pipe in acommunicating way through a tee; the other end, connected by the tee, of the water inlet pipe communicates with a first water storage cavity formed in the ground; two conductive plates are arranged at the top of the first water storage cavity; a second water storage cavity is formed in the plant wall body; and the second water storage cavity communicates with a cavity and is provided with a pressure valve. The water storage plant wall for the sponge city has the following advantages: the effect of accumulating rainwater under the condition of dense rainwater is achieved by the first water storage cavities arranged on the two sides of the road and the second water storage cavity arranged in the plant wall, so that the treatment elasticity on rainwater by the whole city is improved; and furthermore, heavy metal in road runoff rainwater is enriched by heavy metal hyperaccumulators , so that sewage formed by the rainwater is subjected to middle-end treatment and pretreatment and large load of a sewage plant during tail-end treatment is avoided.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a water storage plant wall for sponge cities. 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 plant wall is a wall made of green plants. It uses the super adaptive ability of the plant's root system to the growth environment, so that the plants that inhabit the flat ground in nature grow permanently on the vertical building wall. And architectural decoration provides a new type of organic ecological materials. [0003] In the concept of sponge city, the flexible treatment of rainwater is the key. In cities with more and more frequent rainfall in the south, the workload of sewage plants in rainy weather is greater....

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems in the prior art that the sewage treatment load is relatively large in areas with frequent rainwater, and the effect of the terminal treatment of sewage in the prior art is poor, and a water storage plant wall for sponge cities is designed.
