Problems solved by technology

The second reason is that the design standards of most drainage pipelines cannot fully meet the requirements of extreme weather, so some areas will accumulate water
The sump can be used in special engineering projects such as the Olympic Games and the World Expo. It is currently unrealistic to build a large number of these expensive and difficult sumps to solve the problem of urban water accumulation

Embodiment Construction

[0015] figure 1 The first type of area in is denoted by 1, representing urban roads, including motor vehicle lanes, non-motor vehicle lanes and sidewalks. The second type of area in the figure is denoted by 2, which represents the neighborhoods surrounded by urban roads, including enterprises, institutions, residential quarters, urban squares, urban green spaces and other areas except urban roads. The second type of area also includes roads, parking lots, squares, green spaces, buildings and other sites with different functions.

[0016] figure 2 The number 1 below corresponds to the first type of area, and the number 2 below corresponds to the second type of area. Among the figure, 3 is the urban drainage main pipe, 4 is the drainage branch pipe, and 5 is the drainage flow regulating device, which can be devices such as gates and valves. Among the figure, 6 is an overflow pipe, 7 is an overflow tank, 8 is an open rainwater storage tank (green space, etc.), and 9 is a plan...

Abstract

The invention discloses a method for reducing water on urban streets which builds rainwater accumulation devices in residential quarters or other public areas such as squares, parks and grassy areas without affecting the traffic, wherein the rainwater accumulation devices are communicated with urban sewerage backbone network through drainage branch pipes with drainage flow regulating devices. When it rains, the rainwater on areas except the urban streets firstly flows in the rainwater accumulation devices, then water in the rainwater accumulation devices is drained to the urban sewerage backbone network designedly and organically according to the flow set by the drainage flow regulating devices to outflow. The constant flow organically drainage is carried out according to different zones and different time intervals along the rainwater accumulation devices, the rainwater branch pipes and the backbone pipes so as to solve the conflict that the drainage capacities of the drainage backbone pipes and river channels are not enough as rainwater is drained intensively in short time, and reduce the influence of standing water to the work and life of people.

Description

technical field [0001] The invention relates to a technical solution for improving water accumulation in cities and their roads, in particular to a method for reducing water accumulation in urban roads. Background technique [0002] Waterlogging on urban roads caused by rain is one of the problems that people have a lot of opinions on the government, and it is also a problem that many city managers are trying to solve. [0003] Let's take Beijing as an example. As the capital, Beijing has great advantages over ordinary cities in terms of technology and financial resources, so Beijing's municipal facilities are relatively complete, but Beijing is still plagued by waterlogging on the roads. Beijing's drainage network is composed of trunk lines and branch lines. The standard of the drainage pipe network mostly refers to the standard of the trunk drainage pipe network. The general regional trunk line design standard is one to three years, which is equivalent to 36 to 50 milli...
