The Central Meteorological Observatory issued a yellow typhoon warning at 06:00 on September 4: The center of this year's No. 11 typhoon "Haikui" (HAIKUI) moved into the southern Taiwan Strait around 7:50 pm yesterday (September 3).
It is expected that the "sea anemone" will move westward and northward at a speed of about 10 kilometers per hour, gradually approaching the coastal area at the junction of Fujian and Guangdong, and will land on the coastal area from Zhangpu, Fujian to Huilai, Guangdong on the morning of the 5th (tropical Storm level to severe tropical storm level, 23-28 m/s, level 9-10), moving westward after landing, and gradually weakening in intensity.
Typhoons are extremely destructive natural disasters that often bring heavy rainfall and strong winds, which can easily cause floods. In the face of natural disasters, it is very important to minimize the impact of disasters and protect the safe operation of urban lifelines. Next, let's discuss the relevant measures and precautions for waterlogging prevention and drainage work in typhoon days.
First, clean up the drainage facilities in time. The smooth flow of drainage facilities is an important prerequisite for preventing waterlogging. Before the typhoon comes, clean up urban gutters, sewers, rainwater grates, etc., to ensure that they are not blocked by garbage, sand, and leaves, so that rainwater can drain quickly. In addition, check whether the water pump is operating normally to ensure that it is in good working order.
Second, do a good job of preventive measures in low-lying areas. Low-lying areas are more likely to accumulate water, so before the typhoon comes, it is necessary to strengthen the construction and reinforcement of drainage pipe networks in these areas. For example, a temporary water pump can be installed in advance to pump out the accumulated water; on rainy days, check the drainage ditch and unblock the blocked place to ensure smooth drainage.
Third, before the typhoon comes, we must strengthen the dispatch and arrangement of personnel and materials. If necessary, early evacuations can be made, especially for those living in areas prone to flooding. At the same time, it is necessary to make good material reserves, including food, drinking water, rescue equipment, etc., in case of emergency.
Fourth, typhoon days also need to pay attention to comply with relevant safety regulations. When avoiding going out, try to stay in a safe place and avoid contact with sewage and stagnant water to avoid the risk of infection. At the same time, pay attention to avoid fire caused by electric shock and electrical equipment failure.
While doing the above related measures and precautions, using the new generation of urban lifeline intelligent monitoring system for real-time monitoring is also an effective measure to help cities scientifically prevent floods and waterlogging.
WITBEE®Wanbin®Urban Waterlogging Monitoring and Early Warning System establishes integrated drainage safety covering "source-network-station-factory-river" by deploying intelligent monitoring instruments in urban low-lying waterlogging areas, tunnel culverts, and sunken overpasses Operational monitoring, providing water level analysis in urban waterlogging risk areas, combined with water level and flow monitoring of rainwater pipe networks around waterlogging-prone areas, providing analysis data for evaluating the drainage capacity of low-lying and waterlogging-prone areas, and providing early warning information for pipe network operation in a timely manner to meet daily needs Management, operation scheduling, disaster prediction, early warning and forecasting and other functional requirements ensure timely alarm and efficient disposal of dangerous situations, ensure pedestrian safety and avoid traffic accidents, and provide scientific decision-making basis for pre-flood, mid-flood and post-flood during the flood control period , to provide data support for subsequent engineering planning and transformation.
Introduction to some intelligent monitoring instruments for waterlogging prevention
1. EN200-A2 water logging monitor
The waterlogging and waterlogging monitor is a water level sensor for road area water monitoring. It has built-in AIDMP anti-interference waterlogging dynamic monitoring technology, which is suitable for dynamic monitoring of waterlogging in complex road environments such as falling leaves, strong mobility of people and vehicles, and anti-fog , Anti-pollution, anti-interference ability. Provide data support for real-time online analysis of urban waterlogging, waterlogging monitoring and early warning analysis, and waterlogging area retrieval analysis.
2. Pipe network water level monitor EN200-D2
The pipe network water level monitor adopts micro-power consumption design, built-in super-large-capacity lithium sub-battery, and advanced power management technology, 5-minute collection frequency, 30-minute reporting frequency, and can last for more than 5 years. The overall sealing design is adopted to improve the overall waterproof, dustproof and high and low temperature resistance performance, and the waterproof level can reach IP68, which is suitable for extreme environments such as high temperature, high humidity, sewage and water immersion underground.
By installing a pipe network water level monitor on the well wall in the inspection well, key data such as water level and abnormal movement (illegal removal and movement) can be sensed in real time. When the underground water level exceeds the threshold and the equipment moves abnormally, an alarm will be activated to notify the monitoring center at the first time, so that the staff can quickly locate and deal with it in a timely manner. Dynamically grasp the stagnation state of water in the underground drainage pipe network, analyze the drainage and transportation capacity, and find out the siltation and blockage of the pipe network in time.
3. Millimeter wave water level monitor EN200-R1
High-precision millimeter-wave radar detection technology and anti-interference water surface dynamic monitoring technology can accurately eliminate interference from moving objects such as ships, floating objects, and falling leaves by identifying water surfaces and objects, effectively reducing monitoring errors and data disturbances.
By installing millimeter-wave water level monitors at key nodes of rivers and lakes in urban areas, real-time monitoring of the water levels of rivers and lakes can be carried out; when the water level of rivers and lakes exceeds the threshold, the sensor will automatically upload the alarm signal to the system platform, which is convenient for the staff to quickly locate and deal with it in time , to provide data basis for river and lake intrusion.
Doing a good job in flood prevention and drainage in typhoon days is very important to reduce disaster losses and protect people's lives and property. Through technological empowerment, timely cleaning of drainage facilities, strengthening the prevention of low-lying areas, rationally dispatching personnel and supplies, and complying with safety regulations, we can better cope with the challenges brought about by typhoons. Please also pay attention to weather and traffic information in time. Take precautions in advance.
