After the torrential rain the waterlogging of city is not only a technological question
Ri Lian come, the intersection of the South and the intersection of experience and better the intersection of rainfall and weather large, cause millions of people to suffer from disaster, serious waterlogging takes place in a lot of cities, the vivid city turned into " waterside town " in the twinkling of an eye in the past , " land that abounds in rivers and lakes " . The torrential rain is lowered suddenly, the waterlogging of city, the relevant administrative departments of a lot of cities all point out, the water drainage system standard in the city is too low, design lagging behind etc., block the main reason to drain flooded fields rapidly. For example, the officers of affair office of municipal water in Wuhan think, Wuhan is the old city, the existing underground drainage system can't already adapt to the development of the city of today. However, such speaking the diction is obviously a bit specious, even is suspected of shirking one's responsibility. Because nearly the heavy rain causes the waterlogging of city, will all present such a statement each time, go over for many years, why drainage system of city these change a bit? Should make a self-criticism most, I'm afraid it is still the thinking of development of urban construction at present, it is even the conscience of the urban builder. " old city " The sufficient reason it is not waterlogging of city. Qingdao is the old city too, and " modernization " Earlier city, however, a set of drainage systems that the German invader stays a century ago, still contributing a century later, its corrupt mode that shunts of rain, even until today, a lot of cities of China fail to accomplish. Then, how is the new city? Nanchang encountered the rare waterlogging in the history in 2003, thereafter, the locality invested more than 2 billion yuan to transform urban drainage system, the local media has declared, will not " float on water " again with self-confidence Awkward scene. New enough? Equally a few days ago heavy to rain, collapse at the first blow, street become gone angling to navigate. Over these years, what domestic city's development is bragged about is often a speed, in the almost crazy urban great development process, plan to be broken through repeatedly, technological organization and what the personnel complied with are not but science but an administrative decree, hasty expansion, the planning making unpredictable changes, careless construction, can only leave city the infinite hidden danger. In the words of officer of Department of Construction of Zhejiang Province, " compare with ground construction of city of the spuring on the flying horse type in recent years, the construction of the urban drainage system but can't catch up with the paces " . In this sense, the urban road that the public condemns each time becomes " zipper " The phenomenon is just a sign too trivial to talk about. Scholar Long Yingtai once distinguished whether a country was developed, the once down-pour has fully rained for 3 hours with the heavy rain, "if you stroll propping up the umbrella for a period of time, discover the bottom of a trouser leg is wet but not dirty, although traffic does not stop up slowly, the water accumulation of slipping of although the street but not, this is probably an advanced country " . Likewise, once down-pour, it is really modernized, humanized reagent of a city too. The moustache is printed refinedly and gently on 2011.06.24 in " China Youth News "
