The new bridge crossing in Zaporozhye
Now in our country are not so common global infrastructure construction (EURO objects do not count), and those that are, are often protracted and subject to various scandals. It happened in Kiev: the new bridge would be the pride of the national bridge construction, and has become protracted, which is now very vague prospects of the human realization of the initial project. But how can that be, you ask, because this year is the construction of a very rapid pace? Yes, it is, I will answer, but it does not mean that the construction goes as smoothly as it should be. In addition, a series of events, which I will discuss below, this construction gives a sad tone.
Dnieper River in Zaporizhia can be crossed only in two places: in the bridge Transfiguration and Dnieper. There is, however, another bridge with Khortitsa on the right bank, but it still depends on one of the bridges of the Transfiguration. Both transitions are some nuances: for example, bridges Transfiguration just one lane in each direction and a very sharp turns at arrivals / congresses, which severely limits the speed of transport and their capacity. The need for construction of new bridges has ripened for a long time, and the first progress in this direction began during the Soviet era. By the way, in addition to today's subject, the plans had two bridge crossings: southern and northern bypass, but in which the future they will be built (if you will), you know, is not known.

For greater clarity of today's post show photos, found in the vast web (author, alas, remains unknown). In the foreground is the bridge across the channel of the Transfiguration of the Old Dnieper, then the route passes through the island Khortytsya to bridge the Transfiguration through the mainstream. In the background DnieproGES.

Preparatory work on the track of a new transition began in 2003, and in 2004 finally began the construction itself. However, immediately after the start of construction work suddenly it became clear that the track transition passes Concha Zaspa so quickly became the object of long-term construction is almost the same age as Podolsky bridge. Moreover, if in Kiev, the main issues is the construction of Congresses / arrivals on the bridge, in Zaporozhye everything is exactly the opposite: congresses and races have a very high availability, but with the bridge across the Dnieper there are more questions than answers. The situation is further aggravated the recent redrawing of contractors and the ensuing major revision of project documentation. At the beginning of the construction cost of the bridge was estimated at 1, 9 billion. UAH. After six years (as of 2010) due to various setbacks inflation, exchange rate fluctuations and other perturbations estimates increased to 5, 2 billion.
The new transition will have a length of 9, 1 km, 2 bridge over the Dnieper and 6 traffic interchanges. Transition must duplicate the track bridges the Transfiguration, greatly enhance transport hubs on the approaches to the bridges and increase 2 times the capacity of the existing crossing the Dnieper. Neither the transition nor the bridges do not yet have a name. All objects conventionally referred to as "Construction of the twentieth."
Few torment you track scheme and the designation of sites to be easier to navigate further. In terms of red marked the bridges across the Dnieper sleeves, pink - viaducts and overpasses, sand - the road along the embankment. All objects with the 1st to the 17th Construction (except the Buildings 4 - bridge over the old channel of the Dnieper River) have some degree of readiness. Starting with the construction of 18 and more - a willingness to zero. This year, the money has been allocated more than usual, but because of changes in the bridge project, the funds mainly went into the intersection and overpass. Some of them now have virtually 100% availability, although not soon need: no bridges across the Dnieper the rest of the bridge do not solve the underlying problem.
All buildings on the transition section on the opposite direction of motion. The width of the passage in one direction (14, 25 m below the three stripes) allows you to temporarily skip the 4 lanes (2 in each direction) and start the transition operation, built entirely only half the facilities. In principle, the idea is to pass on the move often sounded more recently, so you may notice that some of the horse-track facilities is more readily compared to the grassroots.

4.
The route of the bridge on the right bank begins with the construction of 1, the main part of which - over the railway overpass and interchange with the existing highways (its edge is seen on the left in the photo).
5.
This portion of the bridge was under construction the last few months has been particularly active. Now it is almost 100% availability.
6.
The same with the opposite side of the junction. The congress with the new viaduct (right) and abutting the road from the bridge Transfiguration:
7.
Older areas are also combed and reconstructed. The road in the photo goes to the bridge through the channel of the Transfiguration of the Old Dnieper:
8.
Continued Facilities 1 - mound new road leading from the interchange to the future bridge over the Old Dnieper. It is not the first month of sound loud slogans to pass the 1st place of the Zaporozhye bridges until the end of this year. From the outset, the appearance of these slogans was clear (and now even more so), that actually bridges across the Dnipro put in this year will not be. It is very likely that this year (or early next year) will hand over construction of 1, which is largely meaningless without a bridge and leads nowhere. Nevertheless, there have caused even counting ...
9.
At the end of the embankment road ends before Constructions 3 - Pier leading out the future road to the bridge over the Old Dnieper. There is only willing to support.
10.
Between the main bearings arranged temporary supports for sliding span bridge across the Dnieper River (just below us more about this talk).
11.
Now it is completed before the last abutment structures 4 - bridge over the old channel of the Dnieper.
12.
In fact, the willingness of the bridge - 0%. And here's why.
13.
Initially, the project involved the construction of a bridge crossing the bridge frame-type (so-called "running doe"). This solution was chosen not only because it allowed a new bridge to link nicely with the old. The bottom of the Dnieper in the place extremely unfavorable for building it supports: on the bottom are two faults, and there are numerous boulders. Thus, the most viable option - to base a bridge on the granite slopes of the shores.
So I had to look at the old bridge project. The distance between the abutments - 340 m, the length of the span of the bridge between the legs "deer" - 264 m, height of passage over the water - 55 meters. The bridge could be the biggest bridge in the world RAMS model for bridge builders and other countries.
14.
For the construction of "running deer" in Sevastopol was built floating crane 1200 (the so-called Project 50370) - Installation of the elements of the bridge was carried out large blocks weighing up to 1,200 tons. The main advantage of large-block assembly - the bulk of the work is transferred to the bank, that is .e. almost at the factory. It goes without saying that the crane was conceived not only under the bridge, but also for other national transport projects, especially because the crane would state that would allow to save on rent of lifting equipment from other suppliers and the cost of its construction would have quickly paid off .
Everything went on as usual, until the recent reshuffle began with the change of contractor. To solve the problem of long-term construction of the bridge, a year ago, received the status of construction nationwide. This has changed the customer and the gene. contractor. Construction of a bridge across the Old Dnieper went to Planet-bridge, which, being the owner of the floating crane "Zachary", for natural reasons did not want to give someone else the opportunity to mount a bridge crane. However, to do "Zachary," which has a total capacity of 680 tons, it is necessary to carry out the installation in smaller blocks and make the riverbed temporary supports. However, using smaller units to achieve the same quality on the weight of initially mounting complicated and expensive. Plus scheme RAMS bridge there are a number of important points that do not allow the assembly of certain elements of the mark. Well, in the end, the cost of construction is increasing because of the increase in the number of temporary supports, which are also oh how difficult to put in there the track. Is there a real savings in this budget at the refusal of the floating crane 1200. - A moot point. However, for unknown reasons, the choice was made in favor of "Zechariah," which, by the way, for a year is no traffic at Darnytskyi bridge (although many media outlets still circulate information that "Zachary" is restored in Nikolaev) and accordingly, no he can not mount a very long time.
In the appendage to it at the beginning of the year the authorities had been issued to specify the complete construction in 2012. Restore to an emergency order "Zachary" Nobody ran to finish the floating crane 1200 no one would have had, and to be spent for its completion it is also the desire not increased, so easy the movement of the hands of the state this year from its completion finally abandoned, and the project "running deer" was sent into the furnace, and in return he is now going to fence the usual litany girder bridge. At the same time, we have gone nowhere a few years of design work, as well as a berth in Krivoy bay prepared for assembly of structures "running deer". As for the bridge beam, in the absence of the two floating cranes, it was decided to mount a sliding spans. This remains to be seen whether supply will be able to support in line with the constant (due to the already mentioned Geology) and what actually will result "savings" from the failure of the "running deer».
The one girder bridge on a new project:
15.
In the meantime, attempts spudded in the bottom and find stable bedrock or to no avail.
16.
Old bridge and new bridge overpass on Khortitsa:
17.
In the next part of the bridge - viaduct on Khortitsa (Structure 5) - all ready to support and started the assembly of metal structures overpass:
18.
Beams is mounted only on horseback (northern) part of the journey.
19.
Between this overpass and interchange to the main channel of the Dnieper new route runs along the island next to the old road. All this economy is in varying degrees of readiness, but look there is nothing special, so we'll move on. Decoupling before the main channel of the Dnieper and the race / Downhill on the cable-stayed bridge (Buildings 6, 7, 8, 9):
20.
Structurally, the isolation is almost ready. There will be unleashed streams with the new and the old bridge, as well as several adjacent roads.
21.
Horse Congress of the bridge is almost 100% availability, and, judging by the way it performed contiguity to the ring junction, it is temporarily imprisoned under movement in the wrong direction, based on the half start-up of the bridge.
22.
For interchange overpass road again interrupted:
23.
Next is the 10th construction of the bridge - cable-stayed bridge across the mainstream of the Dnieper.
24.
Cable-stayed bridge will be, perhaps, the dominant construction of the new road.
25.
The bridge has a length of 660 m (five spans of 80 m and a length of navigable span of 260 m, suspended by the rigging).
26.
How will the bridge in finished form:
27.
28.
On the part of Khortitsa fully prepared to support:
29.
It was assumed that the floating crane 1200 will be fully mounted beam cable-stayed bridge in sections of up to 82 m and weighing up to 950 tons.
30.
But what will happen now the installation of structures - is unknown. At present, the project documentation for this part of the bridge has not changed.
31.
Shipping bridge spans will be held by two pylons, and guys with a diameter of 95 mm. The height of the pylons - 151 m (166 above sea level), the size of one "leg" of the pylon at the base - 2, 6x4, 9 m.
32.
Pay attention to the small islands of granite pylon - "ooh" and "sigh" (oh, and the name). It was assumed that the pylons will be built on them, but then these islands have found some historical value and the road bridge slightly shifted.
33.
For concrete pylons using automatic climbing formwork. Ie to move its valve is not required.
34.
Decking has four levels.
35.
Let's go up to the top level of the formwork. Photo: issues of reinforcement cage of one of the legs of the pylon. Two weeks ago, work has already been conducted at the level of 122, 6 m. By the way, the upper area of formwork so good in the wind
36.
In the photo above in the concrete wall of the pylon visible slot - there is a node ankereniya guys:
37.
The newly installed tower. Legs pylons taper towards the edges, so the longer they are, the more they lean towards each other. Above will be installed stationary concrete bridge between the legs, but if you do not rasperet feet now, then it will have to put too much effort.
38.
As I said, the pylon with stunning views of the surrounding landscape and, in particular, to bridge the Transfiguration.
39.
View of the pylon top:
40.
Next on our way buildings - from 11 to 16 (interchange on the left bank):
41.
Before them there are only installed steel beam span cable-stayed bridge:
42.
The beams are raised above the rest of the interchange. The same situation will be installed and the remaining beams of the bridge - it is necessary to facilitate the process of fastening the shrouds. After the suspension guys beams will be omitted in the design position.
43.
Upstairs:
44.
45.
The very isolation almost entirely of composite with four arms radiating to the waterfront.
46.
Now there is an active concreted slabs of the carriageway.
47.
48.
49.
The only exception - Construction of 16. There were built to stand and then is not going to work.
50.
Stove directions for the construction of 15 is already completely ready.
51.
End of the 15th Congress of Buildings and Facilities intersection with an overpass 14:
52.
Check with the construction of the embankment 14. In the future, the left of the check will laid a new road.
53.
Formwork for concreting slabs directions for the construction of 13:
54.
The construction of 13 ends the temporary ramp to the promenade. In the future, to the left of the overpass will take the new route, and this building will be a stop:
55.
Congress goes under the bridge that leads from the bridge of the Transfiguration and was built for the passage of a new line under the puncture in the embankment of the railway:
56.
On the other side of the railway line, where will the main route of the bridge, there is nothing there. Only in some places it made retaining wall and strengthened the mound itself for the construction of a puncture.
57.
On this for today.
