I watched the Chairman's video about the underground part of the Bolshoi Theater in Moscow. Interesting analytical material and competent, logical presentation. As always, it became interesting whether during the reconstruction of the Bolshoi Theater they dug out 27 meters of dungeons, or was it actually the underground part of the building that was built from scratch? And this is what I found …
To begin with, Ilya did not touch upon the subject of the process of the Bolshoi reconstruction itself. There are plenty of photographs of this process. And according to them, one can draw some conclusion - was it digging up something more ancient, or the builders built an underground part under the theater in the volume of several floors.
Modern reconstruction, which took place in 2005-2011. - the third in the walls of this building. Perhaps the most global one.
Five underground floors were made according to the project. And many readers have a question: how can one build underground five floors under an existing building? Maybe, in reality - it already happened? They just dug it out, reinforced it with concrete. Additional columns and walls were erected.
Promotional video:
Premises named according to the project before reconstruction. For some reason, the top diagram and this one are different. This diagram shows that underground floors have not been made (or dug out) under the theater. The second slide shows this underground cavity in the center of the theater.
Maybe the initial reconstruction project is shown here, but in the process of work you realized that you need to dig everything up? Therefore, the estimate has increased from 11 billion rubles. up to $ 1.5 billion:
But, most likely, everything is correct. The upper project shows the perimeter, and the text below shows the inner underground part of the project. In this plan they are shown together:
But how could an underground pit be dug while preserving the existing building?
With the help of modern tunneling technologies and monolithic construction of buildings. Yes, these are very expensive jobs. It would be cheaper to build a building from scratch. We love such objects. Allegedly preserving the old look and walls of the old building - they spend money on three new ones. But this is a separate topic that has nothing to do with us.
Essentially the destroyed building of the Bolshoi Theater and the process of monolithic works (on the second slide).
I found a couple of photos of the process of extracting soil from under the building on the Internet. For some reason, photos are all paid. Therefore, here are only their free previews with watermarks:
They were reinforced with columns, the soil was removed by mechanization, the floors were monolithic with concrete and the columns were moved deeper. Or the technology can be described in more detail by specialists from the field of tunneling.
Design and implementation in concrete.
Well, in conclusion, in order to make a complete picture of what the builders did here: they dug up the ancient undergrounds of Moscow or built underground floors under the Bolshoi Theater - watch the video from the Chairman.
Perhaps this is my first post with the exposure of the version of the buried floors and ancient buildings of antediluvian cities. As it seemed to me, on the basis of the photographic material studied and the descriptions I read about the project and construction, this is still the construction of underground floors with the development of gigantic sums.
However, some questions remain. For example, there are such comments (in a group in VK from the Chairman):
Were these reconstructed underground floors or new ones?
What did not notice - ask in the comments, we will try to understand this object. But this example does not negate the strangeness in other buildings, including the Polytechnic Museum, the walls of which go deeper into at least three floors not documented earlier. And according to other information, and at 18 m.
