Flat roof rainwater regulation and storage device and method

Abstract

The invention discloses a flat roof rainwater regulation and storage device and method. The flat roof rainwater regulation and storage device comprises a regulation and storage pipe section and a connecting pipe section. The regulation and storage pipe section is provided with a plurality of regulation and storage outlets from top to bottom. The connecting pipe section is used for connecting the regulation and storage pipe section and a building roof rainwater down pipe. The pipe diameter of a regulation and storage pipe is larger than that of the building roof rainwater down pipe. An enclosure filtering frame is arranged on the outer periphery of the regulation and storage pipe section. According to the device and method, peak flow can be effectively lowered, city inner inundation can be relieved, initial stage runoff pollution is controlled, combined system overflow pollution is lowered, a city sponge function is improved, and city development sustainability is improved.

Description

technical field [0001] The invention relates to the technical field of outdoor drainage and rainwater treatment, in particular to a flat roof rainwater regulation and storage device and a regulation and storage method. Background technique [0002] With the rapid development of urbanization, the area of ​​impervious areas has increased rapidly, blocking the infiltration channel of rainwater and destroying the natural circulation process of rainwater. The traditional rainwater drainage system design is guided by "fast drainage", which results in increased pressure on downstream drainage pipes, combined system overflow (CSO) and frequent waterlogging. Especially in our country, in recent years, rainstorms have led to frequent overflows of drainage pipe networks, and combined overflow pollution has brought serious pollution to water bodies, seriously affecting the lives of residents and bringing huge economic losses. Therefore, the traditional rainwater drainage system has bee...

Problems solved by technology

[0004] In order to solve the harm to people's personal and property caused by the single function design of the existing outdoor drainage system, ignoring the comprehensive rainwater management, low urban regulation and storage capacity, easy waterlogging in rainy season, combined overflow pollution, and serious pollution of water bodies and damage to the ecological environment, effectively realize the controllable discharge of rainwater, reduce the flow peak, reduce the pressure on the city's current pipe network, effectively reduce the risk of urban waterlogging and combined overflow pollution, increase the city's sponge function, At the same time, roof rainwater can be filtered and combined with rainwater recycling facilities to save water resources to a certain extent and relieve urban water shortage
