Concave rainwater storage and dispatching pool for green space and decentralized rainwater storage and dispatching pool system

Abstract

The present invention discloses a low elevation greenbelt rainwater regulation scheduling pool and a distributed rainwater regulation scheduling pool system. The distributed rainwater regulation scheduling pool system comprises a low elevation greenbelt (1), a rainwater overflow well (2) and a rainwater regulation scheduling pool (7), and water storage, drainage and supply which are integrated with a rainwater pipe network or a sewage pipe network are achieved. Compared with the prior art, rainfall runoff and flood detention can be effectively adjusted, runoff pollution can be reduced, and purification, storage and utilization functions of rainwater are fulfilled; and the system is tightly combined with the rainwater and sewage pipe networks of a city, the problems of urban inland inundation caused by rainstorm, the runoff pollution caused by rain wash, and rainwater resource utilization are solved, water storage is scheduled according to drainage ability of drainage pipelines, an important means is provided for sponge urban construction, and the system has outstanding social, environmental and economic benefits.

Description

technical field [0001] The invention relates to the technical field of rainwater resource utilization and water supply and drainage, in particular to a design method of a sunken green land rainwater storage and dispatching pond. Background technique [0002] With the significant acceleration of the urbanization process in my country and the continuous expansion of the city scale, a large number of artificial buildings have increased the hardened ground in the city, and the increase in the impermeable area of ​​the underlying surface of the hardened ground has led to an increase in the runoff coefficient of rainwater and a faster confluence speed, resulting in During urban rainstorms, street flooding and groundwater reserves decrease, resulting in serious urban water and soil erosion and flood drainage problems. At the same time, the runoff pollution caused by rainwater scouring the ground also increases the difficulty of urban sewage treatment. If the initial rainwater after ...

Problems solved by technology

[0006] Based on the problems existing in the above-mentioned prior art, the present invention proposes a sunken green space rainwater storage and dispatching pool, and designs a system that integrates the sunken green space, rainwater storage and rainwater dispatching to more effectively regulate rainwater Runoff and flood detention, reduce runoff pollution, and realize the purification, storage and utilization of rainwater; at the same time, the system is closely integrated with the city's rainwater and sewage pipe network to solve urban waterlogging caused by heavy rain, runoff pollution caused by rainwater erosion, and The resource utilization of rainwater and other issues, according to the drainage capacity of the drainage pipes to dispatch and store water, provides an important means for the construction of sponge cities, and has outstanding social, environmental and economic benefits
