Know how to build a bridge that will stand, without repairs, more than 2 thousand years? But in Rome knew, and I do not understand why those ancient technologies are not currently used.
In fact, today the oldest bridge in the world is a bridge located in Rome called Ponte Milvio, thrown across the Tiber river, which is about 2100 years. The first mention of the Ponte Milvio (Ponte Milvio dates back to 207 BC is the time of the 2nd Punic war between Carthage and Rome. Approximately 110-109 B. C. E. under the decree Marco Emilio Scauro built this stone bridge.
Here it goes, did during this time has not changed:
It only repaired after damage in various wars, but in General, the bridge is still in working condition. Many of the current engineering structures can say the same?
And anyway, what do you do now there are all sorts of road-building Institute?
Although, I think that the current bridges with those of ancient Roman, of course, does not compare. Well, think about it: how many passed-passed, even for 2 thousand years, this Italian Mostecka? Very few of the people and goods. And which traffic daily through any bridge or overpass in Moscow? That’s what it is!
Construction technology that use today, they are not worse, they are quite different, specially designed under modern conditions. And overpass, which is currently under construction in Shcherbinka (I was there today) -he just is.
We are talking about the construction of autophotoprodazha in Shcherbinka, in the street Anniversary. Here will be built a two-lane overpass (in fact, it’s the same bridge just thrown across the railroad tracks), the length of which is 237 meters.
What it will build? Of steel and concrete, of course. Although options actually wasn’t so little: from the ancient, wooden structures (actually, this option can be considered except in theory) to the hanging bridges (structurally, they are attached to a powerful steel cables, high towers, and the towers are attached to steel cables to additional supports on the Bank). It would be possible to build and fully steel bridge (for example Bruklinskogo about bridge in new York city, built in 1883), or use the arch (as in the construction of the Bay bridge in Sydney, in which a span of 503 meters covered in one huge metal arc). However, there is a small overpass absolutely needed (not that the longest bridge the Akashi-Caico, which in Japan is 1980 meters), so that cost a traditional combination of metal and concrete.
And the overpass in Shcherbinka now Oh as are necessary! At the crossing during peak hours going to the huge traffic jams due to the tight schedule of trains. In fact, 70% of the time in the day the crossing is closed.
At the same time it will be built approaches, and will carry out the reconstruction of streets of 40 years of October, Rail, Novostroevskiy, Staronikolskoe. Build a turning platform for road passenger transport, on the street 40 years of October.
Later I plan to build another passage from Ostaf highway to St. Novostroevskiy.
In total, the flaw will construct 3 km of new roads, that is quite a lot, given that it is not just the road type highway ordinary, suburban, and complex technical facilities.
The work will be completed in 2017, i.e. the wait is very long, as we can see.
Will the new bridge in Shcherbinka some architectural highlight? Don’t know, but benefits to people he is sure will bring very much!
