A non-powered water storage and replenishment system

Abstract

The invention relates to a powerless water storing and supplementing system which comprises a hopper-shaped water guide fiber net arranged underground, a water guide vertical pipe connected with the lower end of the water guide fiber net, a water storage device communicating pipe horizontally arranged below the water guide vertical pipe, and at least one spherical water storage device connected with the water storage device communicating pipe. The lower end of the water guide vertical pipe is inserted in the bottom of the spherical water storage device. The water guide vertical pipe is sequentially filled with a first fragment layer, a percolation and purification layer and a second fragment layer from top to bottom. The tail end of the water storage device communicating pipe is connected with an observation anti-overflow pipe leading to the upper portion of surface soil. A sponge urban concept is fused in the powerless water storing and supplementing system, the water resource circulating system suitable for different environment and regional conditions is formed, water resource loss caused by green land irrigation and rainfall is effectively reduced, the influences of rainfall flood to surrounding ecological environment are reduced to the maximum extent, and therefore urban water resources are protected and reasonably used.

Description

technical field [0001] The invention relates to a water storage and replenishment system, in particular to a non-powered water storage and replenishment system, which is especially suitable for use in urban green spaces and green belts. Background technique [0002] my country is one of the countries with the most obvious characteristics of global warming. Over-urbanization and unreasonable urban development in recent years have also brought a series of complex urban hydrological problems, including frequent floods, serious pollution of rainwater runoff, and water pollution. Resource depletion, etc., have seriously affected all aspects of urban development. [0003] In the traditional water cycle system, the runoff is directly discharged into the urban drainage system or receiving water body through the urban stormwater pipe network. However, when precipitation forms road surface runoff, a large amount of pollutants enter the water body, causing non-point source pollution of...

AI Technical Summary

Problems solved by technology

At present, most of the urban greening in my country uses tap water as the water source, and the utilization rate is very low, which makes the city's limited water resources more scarce, and also hinders the development of the urban economy to a certain extent.
