Multi-stage urban flood disaster emergency treatment method and system

Abstract

The invention provides a multi-stage urban flood disaster emergency treatment method and system, and relates to the technical field of urban flood control. The method comprises the following steps of: S1, setting a water storage station; S2, acquiring the real-time water accumulation depth of the earth surface; S3, judging whether the water accumulation depth is higher than a first threshold value or not, if yes, opening a drain valve, leading the surface accumulated water to a drain pipe network, and executing S4; otherwise, closing the drain valve; S4, judging whether the water accumulation depth is higher than a second threshold value or not, if yes, opening a water pumping valve, pumping the surface accumulated water to a water storage station, and executing S5; otherwise, closing the water pumping valve; and S5, judging whether the water accumulation depth is lower than a third threshold value or not, if yes, opening a water drain valve, and draining the accumulated water of the water storage station back to the earth surface; and otherwise, closing the water drain valve. The multi-stage urban flood disaster emergency treatment method and system are simple, practical, stable and reliable, flood discharge can be conducted at urban positions where water is prone to accumulation, multi-stage emergency treatment is conducted, the urban flood disaster treatment intensity and speed are increased, and the urban flood disaster loss is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of urban flood control, [0002] In particular, the present invention relates to a multi-stage urban flood disaster emergency treatment method and system. Background technique [0003] Building a city with digital disaster early warning capabilities and intelligent disaster prevention capabilities is a new concept of intelligent cities based on big data platforms in my country, and it is also a new trend in future urban development. In recent years, due to the rapid development of cities, the unbalanced drainage pipe network system in old and new urban areas, different altitudes, and different rainfall in some areas, some areas have strong drainage capacity and will not form waterlogging, and some areas have serious water accumulation. The formation of waterlogging will seriously affect people's work and life, and even cause casualties and huge losses. [0004] However, due to the complex terrain in the ci...

In recent years, due to the rapid development of cities, the unbalanced drainage pipe network system in old and new urban areas, different altitudes, and different rainfall in some areas, some areas have strong drainage capacity and will not form waterlogging, and some areas have serious water accumulation. The formation of waterlogging seriously affects people's work and life, and even causes casualties and huge losses

[0004] However, due to the complex terrain in the city and the long period of time for large-scale reconstruction of the pipe network, drainage is usually pumped between the pipe networks, and the accumulated water in the pipe network with a large load is drained into the pipe network with a small load to form a multi-area drainage system. Flood balance, such a common pipe network that cooperates with each other to pump and drain water is a first-level flood control measure, but it is still difficult to take care of low-lying areas in many cities. Now many people are developing a method that is independent of the first-level flood control measures. Real-time installation and use of secondary emergency treatment equipment with quick results is expected to reduce the loss of flood disasters as much as possible before the complete transformation of the pipeline network. However, the research and development of existing secondary emergency treatment equipment is slow, with a large amount of engineering and flexible Insufficient performance, it simply accelerates the ground water to be pumped into the pipe network, which does not have much effect when the drainage capacity of the pipe network is limited
