In contrast, many of our cities, all the articles done on the ground - and built a lot of tall buildings, because it embodies the city's landscape, highlighting the achievements leadership, but underground it? anyway you can not see, so why spend more money wasted? The result is a new society on earth, underground the old society, a typhoon rain and snow to catch up, invisible things, they begin to give you the Tian Du.
In fact, urban waterlogging caused by many reasons, such as the years, many cities are all steel and concrete jungle, surface hardening was more serious, fall to the ground water seepage is not going to become a run-off, totally dependent on the network drainage. You may have read Victor Hugo's novel You know, a hundred years ago, the Paris sewers, has reached 3 m diameter, we can not but admire, when the French vision of public facilities. Our underground drainage facilities? A long time since I left the impression that a worker struggling to squeeze in Bala repair, even if people get in, simply take the steel barrel, you said, so the pipeline can cope with sudden large-scale rainfall do?

But then again, if you are under the rain in order to prevent, to infinitely increase the caliber of the network, with the excess of investment to cope with a small probability event, but also does not seem the economy, how do we go about it ? The Expo, Rotterdam, the Netherlands case, give us a good reference - Dutch national, is below sea level, the occurrence of high risk of waterlogging, so when people in the city made to advance set aside a lot of low-lying areas, such as repair of many Descented Square, it does not rain, they can when the city's public spaces, playing under the rain to look at the temporary reservoir where the water first to lead, and then concentrate on pumping row,Mulberry handbags, or wait for natural dry water, which can be described as double-edged sword.

The first dredging underground drainage system, the second is to increase the pumping station, to work harder to discharge water to the natural river. These efforts, usually difficult to be seen on the surface, but the key moment to play a big role.

This vast system of underground cities, to maintain the lifeblood of the city. A re-appearance of beautiful, bustling, modern city, if the underground system, obsolete technology, planning is unreasonable, then, like a sick person, like internal organs, can not be called true health. And this disease is a chronic disease, gathered in a long time, once the attack it, it will make people miserable.
present, most cities in the underground system of planning, the biggest problem faced is that some performance and utilitarian view of priority issues. Urban planning and engineering, non-specialized thinking, once dominant, could make the technical details are ignored, in order to rush period, the provincial capital, which is not easy remarkable place, most likely to be the first to sacrifice. Take Shanghai Metro Line One and the second line for example, One line is designed and built by German architect, completion of second line from China, although the large surface are similar, but put into operation, the second line The problems arise: for example, subway steps to prevent the intrusion of rain, had been omitted, the result of a rain,Monster beats headphones, rain intrusion subway easily.
, of course, more people appear, it is a road repaired, hired to be dredged constantly, and even people jokes: , buried pipes, repair gas, as long as the surface of the zipper pull on the line. extensive relevant, such as Shanghai, a city like Beijing, underground pipelines are buried, and even the Qing Dynasty, the early Republic, but could not find a drawing that is, that only blind digging. The fragmentation of power sector, to safeguard their own interests too much for anyone to take the overall situation, urban governance is the most troublesome problem, as each department should be independent of the project budget dispute, for example, the water company's people, he just do not want to gas company or the power companies a free ride, all the results with each other, no ventilation, a bit crushed,Moncler jackets, or that the water pipe to the ringing off the hook, or put the cable Waduan the ... ...

But very unfortunately, when all the exposition of the photos displayed in people's eyes, I actually found, of which no one is about the
I think the common embedded integrated communication is not a difficult, difficult in the public interest, we can not eliminate the chain of interest posed by the complex, the hazards of underground network system construction. Sake of small benefits, you'll never not a big account; greed vanity of people, will never understand what is real and common prosperity.
Core Tip: We can also see the heavy rain in Guangdong, Guangzhou, stealing, Shenzhen is safe and sound, it was not that lucky, Shenzhen, eighties and nineties of the last century, Shenzhen has also been flooded may not be On cross, and even visiting foreign heads of state, are people with small boats to rescue itself from the hotel out.

The first half, the continuous rainfall in South China, Guangzhou and other cities to become a flood plain.
