The construction of the Boguchanskaya HPP Bashny.Net

Here the other day to revise their old photos and in the wake of fashion rukozhopieremontstroitelstvo - decided after drinking and his post.

Brief background: 2011 and 2012 I had a chance to work on construction of the Boguchanskaya HPP. In an organization with a long and glorious history in Gidromontazh. Many memories, mostly good. The team Boguchansky Gidromontazh - the best of those that I had to work. And work and human relations to each other, no you krysyatnichestva and intrigues, as well as the classic "man is a friend, comrade and brother" no matter their origin or skin color or from the place from which it came from anything other than personal qualities. Shortcomings were also not do without them, but in general it was so.
Well, for the sim will start to slowly spread and comment on photos, will spread netoropyas, I try to comment in detail about the end - let you know before the end of - please do not break.

So we go, photo1 HPP to overlap, 3 April 2012. 5 red squares - a bottom gates, still remember the "Order 108 YAYU" they have a unique function - pass through a hangar during construction. After closing - the space behind the gates tightly closed with concrete plugs, and they are just standing there, permanently. Closing of the gate - is the beginning of the filling of the reservoir, each such square is made up of six horizontal sections, weighing 50 tons seems everyone (who knows gets better, the exact number - unfortunately forgot) was lowered by two hydraulic cylinders, the process took about 20 hours.



first gate went down.



Meanwhile, the rest of the construction work is in full swing, too, Crane SKR-3500 mounts a gate of the second section of the spillway, because Shutter is not deep it is very "easy" zelёnenkaya section is suspended from a crane weighs 24 tons, the whole gate about 100 tons



The next morning.
The first gate - sat on the threshold. Open the windows so-called working deep spillway.



To assess the scale - you can see the man. And also to use information - through the closed gate (namely through the first, before the close) motorboat often swam in both directions. There were also rumors that especially frostbite comrades - floated through it on the downstream of the dam. Although he did not see the course



By carefully stick eve bitch - measured the levels of reservoirs
podma


General view of



In the scene, lowered gate - two gidrotsillindrami lifting capacity of 250 tons each (blue pandora right). But because of the oil-pumping station were built up of cylinders of different length lines - all is done in the "manual" mode, constantly monitoring and correcting skewed



Then, in the same manner we omitted the other four, and cut off the bottom valves completely. before the close of the last bottom gate level rose, and the water went through a deep spillway.
It looks like 2000 cubic meters per second on the other side of the dam



Three and a half months. It is seen as the level rose.



However, while he was climbing in the surrounding forests swept away the whole forest to kotorgo falls short of water, and all of these logs relate to the dam where they accumulated. To logs are not caught in the equipment or the shutter (not allowing them to maneuver) was provided for protective zapan. But as usual we made - it has not exactly on what counted. The project consists of zapan pontoons fastened with different sizes together galvanized rope was supposed to lay on the beach and the river rising to 15 meters - to raise the decomposition zapan, then it is possible to stretch the boats in the design position. In theory - very nice but so far the river rose to the 15 meters - caused nehily Number of forest, it has accumulated naturally from the dam, the top potsepochke passed agromadny pizdyuley and carefully dyed pontoons for uskoneniya - began to throw into the water tractors without waiting until the water deign them to lift < br />


In the end, it turned out as something like this



in the process of pulling zapani often met locals



There she floats, see



Push tractor, pulling boats



But anyway here is a small island near the dam up. Then it was removed with the help of nanotechnology Skolkovo, put on a barge with an excavator grab, catch logs piled on the same barge and towed to shore, and so two months mudohalis. How much money is raised the water wipers - Do not know, but will love sour, happy for the guys



View from the searchlight masts.

Sawdust at the bottom - it is for insulating concrete. Fill it in winter, when the temperature was below -48 brrrrr



And once welders HST and naronyali in filings sparks, well, it flashed, a pretty juicy, and in a place that climb up there - not that difficult, and without Alps snaryagu impossible (for the average person, not a spider) here as it looked



That's how close. I was under it was passing to the opposite side, so the bottom at a distance of 40 meters felt barbecue, such heat went



uuups. one missed photo, like this laid zapan, hoping that it will raise the water
