Structure for water storage and drainage of pipeline

Abstract

The invention belongs to a structure for water storage and drainage of a pipeline in the rainwater drainage technology and facility systems. The structure adopts the technical scheme that a community rainwater draining pipe is connected to the upstream of a community first outdoor rainwater well; a high-position rainwater pipe and a low-position rainwater pipe are respectively connected to the downstream of the community first outdoor rainwater well; the other ends of the high-position rainwater pipe and the low-position rainwater pipe are respectively connected to the upstream of a community second outdoor rainwater well; a municipal rainwater collection pipe is connected with the downstream of the community second outdoor rainwater well; the pipe diameter of the community rainwater draining pipe is respectively larger than that of the high-position rainwater pipe and the low-position rainwater pipe; the pipe diameter of the municipal rainwater collection pipe is larger than or equal to that of the high-position rainwater pipe; a valve is arranged at the starting end of the low-position rainwater pipe. The structure solves the problems of water storage and flood detention, and effectively, timely and controllably achieves the effect of peak clipping when the rainwater discharge flow reaches a peak value.

Description

technical field [0001] The invention belongs to a rainwater drainage technology and a facility system in the field of construction engineering, in particular to a drainage system with rainwater storage capacity. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". [0003] Sponge city construction should follow the principles of ecological priority, combine natural approaches with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwater resources and ecological environment protection. [0004] The design concept ...

Problems solved by technology

[0005] However, the existing outdoor pipeline drainage method is: the rainwater discharge pipe of the residential area is connected to the upstream of the rainwater inspection well, and the municipal rainwater intake pipe is connected to the downstream of the rainwater inspection well, which only has the function of drainage. The structure is simple, the design concept is outdated, and it cannot be realized. Sponge City Construction Requirements for Rain and Flood Control
