The president of the regular court talks about the lessons of heavy rain: Flood preven

Wang Kai, Dean of the China Urban Planning and Design Institute, believes that the flood disasters caused by heavy rainfall in China recently have brought profound lessons, and it is necessary to comprehensively and systematically improve the level of existing flood prevention and drainage standards.

According to the surging news Sunday (August 20), Wang Kai, who is also a master of engineering survey and design in China, gave the above opinions on the design of Chinese city drainage design in the interview.

Wang Kai pointed out that many places this year's rainfall is a super strong rainfall once a hundred years, and the intensity exceeds the highest actual carrying capacity of flood control and drainage facilities.In addition, the old problems in planning and construction have not been fundamentally resolved, and the construction management is not recognized, which has also led to a large loss. For example, during the construction process, some cities have caused certainExcisibility of occupation.

Wang Kai also said that the superposition of groundwater can also lead to the collapse of the ground and the systemic problem of ecological atrophy. Therefore, some experts have proposed that it is necessary to update the transformation of underground facilities and improve the drainage standards.

Wang Kai pointed out that people's previous awareness of climate change may not be profound enough. For example, after the "7 · 21" heavy rain in Zhengzhou, Henan in 2021, many people think that such heavy rain occurred in North China.After ten or eight years, "I did not expect that it would happen in two years."

He proposed that in urban planning, it may be necessaryTheoretical methods, doing some innovation and even revolution, and referring to improving discipline construction and prediction of urban planning and construction management, which requires the intellectual update of ecological civilization ideas.

Affected by the typhoon "Du Surui", China Huahua Beijing Tianjin -Hebei and Northeast China have been suffering from rainfall since the end of July. Flood geological disasters have occurred in many places. Among them, 33 people died in Beijing in Beijing.Disappearing, nearly 1.29 million people were affected, Hebei Province also reported that the floods had killed 29 people and 16 people lost contact.
