Constructing the ecological greening system of the external wall pipe network of the secondary water reuse building in the sponge city

Abstract

An external building wall pipe network ecological greening system for secondary water reuse in a sponge city, comprising: a rooftop (1), a rainwater collection box (2), water drainage pipes (3), wash basins (4), filters (5), solar panels (6), a computer / mobile phone smart automatic / manual control organic nutrient solution, particle fertilizer / water quality improvement chemical additive and particle / drop box cloud application interaction system (7-1-2), plant growth covers (8), three-chamber pipe-linked pipe-type water circulating plant growth pipe disks (10), optimally cultivated terrestrial and aquatic plants suitable for growing in secondary city water; water channels surrounding the city / water channels surrounding buildings as well as the optimally cultivated terrestrial and aquatic plants suitable for growing in secondary city water, and excess water being discharged to an underground city pipe network after the secondary water is purified by means of plant growth are effective approaches to and provide strong support for the construction of a sponge city.

Description

technical field [0001] The invention relates to the field of external walls of urban buildings, in particular to an ecological greening system for building external wall pipe networks for secondary water reuse in a sponge city. Background technique [0002] At present, on the one hand, water resources are scarce, and on the other hand, rainwater and secondary water from urban buildings are not used, and most of them are directly discharged, which makes the waste of urban secondary water resources a common phenomenon. Save resources, make full use of available secondary water such as rainwater and wash basins, build a sponge city secondary water reuse building external wall pipe network ecological greening system, and create a three-dimensional construction of comprehensive greening in China's modern new urban areas, especially in old urban areas The transformation will produce several times the green area of ​​the ground, with less investment, small transformation, achievabl...

AI Technical Summary

Problems solved by technology

[0006] The rainwater from urban buildings and the available secondary water generated by residents’ lives have no facilities for collection and utilization, and there is no direction for directional use, so the secondary water resources generated by residential buildings have been neglected for a long time. On the one hand, there is a serious shortage of water. On the one hand, it does not make good use of it, and directly discharges the secondary water resources that have entered the interior and exterior of the building, resulting in a huge waste of contradictions

[0007] China's urban modernization construction and development require innovation, new ideas, and new solutions to new problems. If we continue to follow the previous planning and design ideas and obtain "unlimited value possibilities" from the limited urban ground (plane), this road will not work. Unable to meet the needs of China's modern urban development
