Zero-power-consumption lawn water storage system for sponge city

Abstract

The invention provides a zero-power-consumption lawn water storage system for sponge city, and relates to the technical field of sponge city rainwater collection and utilization. The zero-power-consumption lawn water storage system for the sponge city comprises a lawn rainwater collecting area, a pavement road rainwater collecting area, a PP rainwater storage module, a rainwater comprehensive recycling area, a downstream rainwater well and a municipal water supplementing module, wherein, the lawn rainwater collecting area comprises a lawn, a planting soil layer, a medium sand layer, a 300g permeable geotextile layer, a multi-medium filter plate, a lawn water storage module and a concrete foundation layer, and the pavement road rainwater collecting area comprises a pavement road, a broken stone hardcore, a hard water distribution blind ditch / pipe layer, a permeable geotextile layer, a lawn water storage module and a concrete foundation layer. The zero-power-consumption lawn water storage system for the sponge city accords with sponge city low impact development principle, low power consumption principle and elastic sponge city concept, absorbs part of rainwater on site, stores and recycles the rainwater, and better accords with simple and low power consumption principle of rainwater utilization.

Description

technical field [0001] The invention relates to the technical field of rainwater collection and utilization in sponge cities, in particular to a lawn water storage system for odd jobs in sponge cities. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". During the period of time, it can quickly absorb, accumulate, infiltrate, and purify rainwater, reduce the runoff of rainwater, and replenish groundwater. Resources are better integrated into the city's water supply and drainage system to create a reasonable sponge city water system, which can not only effectively protect the original ecological system of the city, but also slowly restore the original damaged ecosystem. The impact of urbanization construction and development is reduced to a lo...

AI Technical Summary

Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides a water storage system for lawns with odd jobs in sponge cities, which solves the problem that the rainwater collection and utilization system in cities in my country is still in the initial stage, and the rainwater utilization technology is still relatively backward and lacks systematicness. The urban construction project has just started, and the technology, capital and project implementation have not yet reached the standards of sponge cities in developed countries.
