First line observations on flood prevention and preparedness in the Huaihe River Basin
2023-05-05
At present, it is an important period for flood prevention and preparedness. The Huaihe River Basin is located in the north-south climate transition zone, with frequent flood disasters. How is the flood prevention and preparedness situation in the Huaihe River Basin this year? What are the new flood prevention measures and methods? The reporter has been participating in the "Huaihe River Basin Flood Prevention and Preparedness Campaign" organized by the Ministry of Water Resources for several days, and has conducted interviews in Shandong, Jiangsu, and Anhui provinces. Large scale projects to strengthen the bottom line of flood control safety stand on the Anlan Tower of Huai'an Water Conservancy Complex, and many large-scale water conservancy projects can be seen: while many ships shuttle on the Grand Canal, the water of the Yangtze River is diverted from south to north via the Grand Canal; After being regulated and stored by Hongze Lake, the water of the Huai River is diverted from the North Jiangsu Irrigation Canal and the Huai River into the Yellow Sea... Rivers, lakes, and seas are interconnected and mutually beneficial. Dong Zhaohua, deputy director of Jiangsu Irrigation Canal Management Office, told reporters that Huai'an Water Conservancy Complex has nearly 30 water conservancy projects such as water (culvert) gates, pump stations, ship locks, and hydropower stations, which play a comprehensive role in regulating water resources of the Yangtze River, Huaihe River, Hongze Lake, and Grand Canal. The Grand Canal Interchange is the second level hub control engineering of the Huaihe River into the sea waterway. It was completed in June 2003, so that the flood discharge of the Huaihe River into the sea waterway and the navigation of the Grand Canal will not affect each other. The second phase of the Huaihe River estuary project started in July 2022 and is currently accelerating the construction of the entire line. After completion, it will enhance the flood discharge capacity of the lower reaches of the Huaihe River and reduce the flood control pressure on the main stream of the Huaihe River. The Huayuan Lake project in Fengyang County, Anhui Province, in the middle reaches of the Huai River, is an important component of the adjustment and construction project for the flood discharge area of the Bengbu Fushan section of the Huai River main stream. The Huayuan Lake flood discharge area has been adjusted to a flood discharge area controlled by gates. The Huayuan Lake project passed national acceptance in July last year, ending the history of explosive flood discharge in the Huayuan Lake flood discharge area. It will play an important role in flood prevention and flood control, as well as ensuring the safety of local people's lives and property. "said Zhao Honglang, Deputy Director of the Project Management Department of the Huaihe Water Resources Commission Construction Bureau of the Ministry of Water Resources. A series of major water conservancy projects are further strengthening the bottom line of flood control safety. Projects such as the Chushandian Reservoir and Qianping Reservoir, the regulation of the river channel, and the reinforcement of general embankments in the main stream of the Huai River have been completed and put into effect. Other low-lying land management projects such as the flood storage area along the Huai River in Anhui Province have also started construction in April this year, and the completion of these projects can improve the flood control and drainage capacity of the project area. Modern technology assists in flood prevention and control. The Three River Sluice is the first gate for the Huai River to flow into the Yangtze River, responsible for 70% of the Huai River's flood discharge. In the hoist room of Sanhe Gate, Guo Jun, the director of Sanhe Gate Management Office, told reporters that every year before the flood season, professional instruments and means are used to "check up" the project. Among them, the Sanhe Sluice has used a horizontal displacement monitoring instrument for the first time to conduct real-time monitoring and ensure the safe operation of the project. At the main entrance of the Huai River into Yi and Huai River into the sea at Hongze Lake, the Erhe Gate, Han Chunqiao, the director of the Erhe Gate Management Office, showed reporters a newly introduced intelligent steel wire rope inspection robot that detects the steel wire rope connecting the hoist and gate of the Erhe Gate array. Flood prevention is the most important thing. If people living in flood detention areas encounter floods, how can they safely evacuate "one cannot miss"? At the Caowa D evacuation post station in Huangdunhu Flood Detention Zone, Hubin New District, Suqian City, Jiangsu Province, the reporter saw a evacuation command board with a transfer route map drawn and marked with a centralized evacuation area
