Method for constructing structures for recycling and comprehensively utilizing rainwater

Abstract

The invention relates to a method for constructing structures for recycling and comprehensively utilizing rainwater. The method is characterized by comprising digging underground reservoirs on the outer sides of building foundations, adhering waterproof coiled material layers along the side walls and the bottoms of the underground reservoirs and then arranging water seepage preventive concrete layers; arranging dirt filter plates in ground reservoirs, forming bottom water pumping pits in the ground reservoirs and arranging reservoir cover plates on the upper portions of the ground reservoirs; preliminarily arranging dirt filter plate buttresses and water level sensors on the side walls of the underground reservoirs and preliminarily forming rainwater pipe connecting holes and municipal pipe connecting holes in the side walls of the underground reservoirs; reserving dirt filter plate step seams at dirt filter plate seams and arranging waterproof coiled materials at the dirt filter plate seams; arranging building water supply pipes at the bottoms of water collecting basins and inserting rear water pumping pipes in the tops of the water collecting basins; communicating rainwater collecting tanks with building rainwater pipes; arranging one-way water interception valves at joints of municipal pipeline connecting pipes and municipal pipelines. The method has the advantages that the structures are convenient to construct, the rainwater on the tops of buildings can be reused, and the rainwater on the outer sides of the buildings further can be sufficiently utilized.

Description

Technical field [0001] The invention relates to a construction method for a rainwater recycling structure, in particular to a construction method for a rainwater recycling comprehensive utilization structure with convenient construction, high rainwater recycling rate, and intelligent control. It belongs to the field of construction engineering and is suitable for construction rainwater recycling projects. Background technique [0002] There is a shortage of water resources in my country, especially in most areas centered on cities. Among the more than 700 prefecture-level cities and above, nearly 400 cities lack water or are severely short of water, and this is increasing. Rainwater is a high-quality fresh water resource in nature. After simple treatment, it can realize the functions of toilet flushing, road spraying, and green irrigation. Reusing rainwater has a significant water saving effect. [0003] The rainwater recycling system is a system that collects rainwater according t...
