Construction of the century, or how to build the Crimean bridge

To realize the full scale of what is happening, you need to see it.

It would seem a bridge and a bridge. But in reality, the construction of the Crimean Bridge is a giant living mechanism that literally buzzes 24 hours per day in almost any weather. Almost 10 thousands of people, more than 500 units of equipment - from giant cranes to conventional dump trucks and asphalt pavers. Thousands of tons of concrete, metal and fittings, hundreds of thousands of huge bolts, nuts and electrodes. This is all the Crimean Bridge, which in the Crimea is called the construction of the century.

So, the construction of the bridge in detail in the photo below.

Construction of the century, or how to build the Crimean bridge

Source aquatek-filips or not, but the Crimean bridge will be the longest at the moment in Russia - its total length is 19 km. Construction is being conducted simultaneously from two sides - from the Taman Peninsula and from the Kerch side.

Most of the bridge will pass on concrete pillars installed in the Kerch Strait, a small part through the island of Tuzla and almost right next to Kerch is the shipping section, over which two giant metal arches have been installed - the railway and the automobile. At the same time it is the highest place of the bridge.

The location of the shipping part near Kerch is due to the peculiarities of the Kerch Strait, which is very small and problematic for shipping. The fairway, in fact, is one here and it is located just near Kerch itself.

So, let's walk from the very beginning of the bridge from the Crimea to its highest point.

2. Here is the "beginning" of the bridge from the Crimea today. The first support of the coastal part is just being prepared: the foundation and reinforcement cage for pouring concrete is ready.

3. Each subsequent support is higher and higher, and quite noticeably. The fact is that due to the proximity of the shipping part to Kerch, the future road must pick up quite sharply in order to climb the 35-meter height of the arched part. Already finished concrete supports. Between them, temporary auxiliary supports of metal structures are visible, which are used for sliding bridge spans and their subsequent installation.

4. In the distance, you can see the newly installed arches of the shipping part and the partially mounted road approach. In the photo it seems that the rise is quite steep. Maybe it's because of the shooting angle?

5. Sea supports are already fully prepared.

6. And the spans of the automobile part are already almost completely mounted on them. It remains to establish only a few spans adjacent directly to the shipping arch and the spans over the coastal part.

The railway part, as well as the support for it has not yet been installed. They will be built secondarily at the place where the technical bridge is now installed to provide construction (most of the pictures were taken from it, all the equipment, building materials, workers' bogs and the technological transport are moved).

7. View from below on the automobile span.

8. The remaining few spans. Support under them finish to cast in the surface part. In the upper left corner - avanbek. The design is in the form of a sloping ski, which is mounted in front of the span structure, in order to make it easier to crawl on supports while sliding.

9. The process of welding huge pipes used as piles to move the main construction platform.

10. The process is quite interesting. Above the place where the pipes are to be welded, a temporary plywood booth is installed - “greenhouse”. This is done in order to protect the welder weld spot from the weather.

11. Here, near the shower of the remains of huge pipes.

12. The farther into the sea, the more massive the concrete pillars. To climb up and down, use temporary closed stairs. Going down on them, of course, is not very convenient, judging by the way the worker does it.

13. Preparing to fill the last support before the shipping arch. The shields of red are the formwork into which the concrete is poured.

14. A look at the technological bridge from the main construction platform.

15. And this look in the opposite direction - just on the shipping spans. On the left - the automobile part, on the right - the railway. Both arches weigh more than 6 thousand tons each, they were collected on the shore from the Kerch side, and then they were floated by sea to the installation site, where with the help of special cranes 35 meters were raised to the height of the supports. Bottom arches, by the way, are different.


17. At the time of installation of arches navigation on the Kerch Strait was stopped. At the same time, ships are already passing under the bridge in the usual manner. On the right in the foreground are temporary piles for the construction platform. It is self-shifting and transfers itself as necessary to the piles that were previously driven into the bottom of the strait.

18. Extreme support for the arch from the Taman side. People are absolutely tiny against its background ... In the background you can see the construction platform from the Taman side. From Kerch (from where the picture was taken) is the same.

19. The armature, which is used to fill the supports, is almost the thickness of an adult’s hand.

20. The worker returns with a cast of support.

21. View of the construction platform almost from sea level.

22. The view from the sea level on the support of the arched part. Its height is 35 meters and, in order to go upstairs, it is necessary to overcome the metal staircase blown by all winds. Just the other day, an elevator was mounted here, but sometimes you still have to climb stairs.

23. A look down from the top point of the arch support.

24. Construction platform on top. There are two huge Liebher cranes installed on it, which lift and move all the necessary materials both to the upper part of the platform and to the lower part where the concrete pouring works are underway.

25. The surface of the railway arch. Still without sleepers and rails.

26. The first car on the car arch.

27. Below is the fill of the connecting part of the support of the arched part.

28. Reinforcement mesh. How much metal is there?

29. This is how temporary scaffolding for high-rise works on supports look like.

30. Attachment points of the various elements of the arch. The inscription "30.09.2017" and the signature - a mark of technical supervision of the adoption of the bolted joint. Each bolted joint is checked for the tension of the bolts, if everything is normal - the representative of the technical supervision puts his signature and the date of acceptance (and also marks this joint in his existing assembly card and puts his signature in the act).

31. All compounds are coated with a special anti-corrosion layer, because the aggressive environment will constantly affect the bridge - the Kerch Strait is famous for its storms and hurricane winds.

32. It is with such bolts that most of the arch elements are pulled together, which, in fact, is a huge designer.

33. Folk instrument)

34. Rebar base of one of the supports.

35. Matrix.

36. A look at the part under construction from the side of Taman. It remains to lay the 4 road span and the Taman part to connect with the arch.

37. I imagine what it is like to work there. In the wind, above the water, at a height ...

38. View of the bridge through the doorway in the railway arch.

39. The inscriptions left by workers.


41. It is also fined ...

42. Under the bridge rush, are vessels.

43. Technological bridge.

44. Formwork elements for pouring concrete piers of the bridge.

45. They, by the way, are thoroughly washed after being removed from the filled elements. And then install on new places for the subsequent filling.

46. Here is the construction of the Crimean bridge at the beginning of November 2017. In a year, in December, the bridge promises to launch 2018 ...

    This is certainly the greatest construction site in modern Russian history.

    We like everywhere to push rusty pipes and fittings. Does type corrosion magically disappear then?
    And the height of the passage under the arch is not small?

      . Rust is oxidation, in the case of alloy steels it goes, and structural reinforcement is even more so.
      the height of the bridge is only for the passage Boreev.

        Yes, what are you?! ... and I thought it was dirt ... figs enlightened themselves .. thanks ...
        about the destruction of concrete from rust (as well as other processes) have not heard?

      Cement will gobble up. Have you tried cement / concrete with your bare hands? And do not try - you will remain without skin.
      And so it becomes with rust.

          This is not rust, this is plaque. GOST 7566-94; GOST 10922-2012 and SP 70.13330.2012 to help you.

            That's how I look at the water in the pipes we have is so interesting ... it turns out this is a guest ...

              I don’t know how YOU have it, but I have normal water in my household water supply. Of course, there are places where the quality of water leaves much to be desired (Obninsk is very hard, Teykovo is an excess of iron), but this is a question for the local authorities. Water treatment is their question. And the problem is not in the pipeline, but in the primary source of water and further water treatment.
              As for the topic originally raised, I repeat - this is not rust, but plaque (which is not surprising in a salty environment - evaporation of sea water, you know, they will give a film of oxides on the metal in a few days). In everyday life, rust is when a detachment of a porous oxidized layer occurs.
              If you already raised this issue, then you need to look at the welded joints of MK. If they do not remove slag, then in this place corrosion is accelerated by 20 times regardless of the anti-corrosion treatment (applied to the seam with slag not removed).
