Difficulties in urban waterlogging control construction

In recent years, with the development of urbanization, urban areas have expanded, and more and more rivers and wetlands have been turned into concrete ground. The number of urban waterlogging points has also increased accordingly. Whenever a city is hit by heavy rainstorms, rainwater cannot penetrate into the surface, and the drainage capacity of the underground drainage network exceeds the load, the “city looking like the sea” phenomenon is likely to occur. How to regulate the waterlogging-prone points is not only the focus but also the difficulty.

Flood-prone areas in cities are usually located in low-lying areas of the city. There are also some high-lying areas that are prone to flooding due to poor drainage. Generally, areas prone to urban flooding include: low-lying areas in urban areas, sunken overpasses, underground rail transit, underground shopping malls and garages, underground spaces such as dilapidated houses and basements, and construction sites.

Difficulties in urban waterlogging control construction

1. Overall status unknown

The rapid development of urbanization has led to a lag in the construction of drainage and flood prevention facilities. In order to implement the “large drainage” concept of waterlogging prevention and control, the newly added facilities have low compatibility and interactivity with the original facilities, and there are data barriers. “Segmentation” and “mutual closure” lead to unknown overall conditions, and unified management and business development are inconvenient.

2. Insufficient monitoring and early warning capabilities

The level of business application support is not high, and the management and maintenance models and means are backward. There is a general lack of modern management means such as real-time monitoring systems, waterlogging warning systems and automatic processing systems, and the degree of intelligence is low. The product integration of the built system is low, operation and maintenance are inconvenient, the functions are relatively simple, and the perception system is imperfect.

3. Inadequate response measures

An effective management and control system has not yet been formed for underground facilities that are prone to cause serious disasters when urban flooding occurs, such as underground roads, underground rail transit, underground parking facilities, and underground commercial service facilities. It is difficult to make accurate judgments on urban flooding and issue early warning information in a timely manner based on real-time meteorological information, pipeline network dynamic information, and traffic information.

Urban waterlogging control monitoring and early warning system

Hrunan’s urban waterlogging control monitoring and early warning system needs to collect data from water level sensors, rain gauges, water level meters, video surveillance, and other scenarios through telemetry terminals, and send them to the monitoring center in real time. Based on the monitoring of real-time water level, rainfall information, video information, and combined with weather forecast information and historical information for the same period, it provides intelligent early warning and real-time alarm for urban waterlogging control.
