Rainwater storage recharging module and system which are suitable for urban green land

Abstract

The invention mainly relates to the technical field of greening projects and rainwater recycling, in particular to a rainwater storage recharging module and system which are suitable for urban green land. The rainwater storage recharging module comprises a closed water storage tank buried underground, and water collecting openings communicated with a water storage cavity inside the water storage tank are formed in the top face of the water storage tank; the rainwater water-storage returning module further comprises a breather pipe installed on the water storage tank and reverse recharging guiding cores capable of generating the capillary effect; the lower end of the breather pipe extends into the water storage cavity of the water storage tank, the upper end of the breather pipe extends out of the water storage tank, the lower ends of the reverse returning guiding cores similarly extend into the water storage cavity of the water storage tank, the upper ends of the reverse returning guiding cores also extend out of the water storage tank so that the reverse returning guiding cores can extend into a planting soil layer upwards, and when the water content in soil of the planting soil layer is decreased, water in the water storage cavity is compensated to the planting soil layer through the capillary effect of the reverse returning guiding cores. After once investment, daily use cost does not exist, and daily maintenance is not required.

Description

Technical field [0001] The present invention mainly relates to the technical field of greening engineering and rainwater reuse, in particular to a rainwater storage and re-infiltration module and system suitable for urban green space, and is mainly applied to urban green space maintenance. Background technique [0002] Due to the increasing shortage of water resources in our country, water for maintenance has always been the highest among all urban green space maintenance costs. In traditional greenbelt maintenance, the water used is municipal tap water or reclaimed water (reclaimed water, also known as reclaimed water, refers to water that can be beneficially used after sewage is properly treated and reaches a certain water quality index to meet certain use requirements). The use of municipal tap water for green space maintenance is a huge waste, and some areas abroad even have legislation prohibiting the use of municipal tap water for green space irrigation. The use of reclaim...

Problems solved by technology

This kind of rainwater storage module is more designed to store rainwater. In actual use, this rainwater storage module still has problems such as occupying a large area, requiring supporting facilities, and high maintenance costs, especially when it is used When it comes to green space maintenance, a series of facilities and equipment such as pressurization, pipe network, and nozzles need to be installed, and the cost has not been effectively controlled
