Method for preventing and treating urban waterlogging

Abstract

The invention relates to the technical field of urban waterlogging treatment, in particular to a method for preventing and treating urban waterlogging. The method is characterized in that aiming at aprecipitation water source in an urban area, precipitation is directly drained to a drainage system in the urban area or the downstream of the urban area through arranging a closed pipeline; for a water source which does not pass through a building to directly drop to the ground, the treatment method is divided into two types, the first type is the terrain low-lying part treatment method, and thesecond type is the terrain fluctuation part treatment method; and for a city with a river in the urban area, a flood control dam is built, a water level monitoring device, a pumper and an alarm deviceare arranged, mounted, and matched, and diverting is carried out on flood through ditches, the closed pipeline and terrain combining so as to prevent the flood and the waterlogging. The method for preventing and treating the urban waterlogging can prevent and treat urban waterlogging in a mountainous area or a basin city and a plain city.

Description

Technical field [0001] The invention relates to the technical field of urban waterlogging treatment, in particular to a method for preventing and controlling urban waterlogging. Background technique [0002] As the urban construction becomes larger and larger, the urban planning lacks the design of underground flood drainage facilities, which leads to serious waterlogging in many medium to large cities during the flood season, especially in recent years. This not only caused hundreds of millions of property losses, but also endangered the lives and property safety of the general public, and even caused some citizens to lose their precious lives. [0003] Urban waterlogging is mainly divided into two categories, mountain basins or other forms of cities and plain cities. Mountain basins or other urban waterlogging sources: one source of waterlogging is the mountain water from the surrounding mountains; the other is the precipitation in the urban area. The precipitation in the urban ...

AI Technical Summary

Problems solved by technology

Waterlogged water sources in mountain basins or other forms of cities: one waterlogged water source is the mountains and waters converging from the surrounding mountains; The water that falls directly to the ground from buildings is currently discharged into the open drainage pipes in the urban area. When the precipitation is too large to be discharged through the existing open drainage pipes, it will cause river flooding in the city; if there are rivers passing through the city, then There are also floods in the upper reaches of the river. Now the urban river and the urban area are not blocked, and the buildings along the river are parallel to or slightly higher than the river embankment. When the upstream flood is too large, it will cause the flood to pour into the urban area, causing urban flooding and internal waterlogging; or A combination of both, ultimately resulting in urban flooding

[0004] Waterlogged water sources in plain cities: one is precipitation in urban areas. Urban precipitation is divided into precipitation that passes through buildings (accounting for at least 30% of urban precipitation) and water that falls directly to the ground without passing through buildings. At present, they are all discharged into urban areas and open to the public. In the drainage pipes, when the precipitation is too large and cannot be discharged through the existing open drainage pipes, it will cause river flooding in the city; Buildings are parallel to or slightly higher than the river embankment. When the upstream flood is too large, it will cause flood water to flow into the urban area, causing urban flooding and internal waterlogging; or both, eventually causing urban waterlogging
