Urban water-logging prevention and control method

Abstract

The invention discloses an urban water-logging prevention and control method. Original rainwater ports are lengthened and extended at the position where water easily accumulates of the ground of an urban main road, stereo rainwater ports are formed in the ground of a sidewalk and side faces of a prismatic table, special grille covers are configured for the stereo rainwater ports, and all-dimensional stereo water discharge is performed through the original rainwater ports and the stereo rainwater ports. By the adoption of the urban water-logging prevention and control method, the water discharge flows of the rainwater port grille covers can be effectively increased, ground sundries and water flows can be prevented from plugging the rainwater port grille covers, and air in a gravity flow pipeline system can be also effectively discharged, so that water discharge is smoother. By the adoption of the method, the cost can be minimized to the most degree, a construction period is shortest, the working amount is the least, only the rainwater ports are reconstructed, underground water discharging pipelines are not required to be reconstructed, the water discharging capability of the urban main road at the low-lying positions can be greatly improved without increase of exhausting and emptying devices of the gravity flow pipeline system, and urban water-logging can be prevented and avoided.

Description

technical field [0001] Urban drainage works. Background technique [0002] At present, in many cities in our country, when there is lightning, thunder and downpour, a large amount of water will be generated in the low-lying places of many main roads in the city, and the rainwater cannot be drained out. Homes, property and cars were flooded. Sometimes accidents that result in personal injury or death occur. Why can’t rainwater drain out? People analyze the reasons for two main reasons: one is that the city is developing rapidly, there are many buildings and roads, some areas are low-lying, and the rainwater accumulates excessively; the other is that the drainage pipe network has a small diameter and the rainwater is trapped Wrapped in sand and sundries, the rainwater outlet is blocked, the air in the drainage pipe cannot be discharged, and the rainwater outlet cannot discharge water. Heavy rain is a natural phenomenon, and no one can change it; there are many buildings and...

Problems solved by technology

Heavy rain is a natural phenomenon, and no one can change it; there are many buildings and roads, so it can only be said that with the development of the city, there will be more and more buildings and roads; the drainage pipes are thin, and of course the newly constructed drainage pipes can be designed to have a higher displacement. It is big, but for the urban drainage projects that have been built, it is not easy to transform
