The destruction of the bridge to the Russian island. Bridge to Russky Island, the longest cable-stayed bridge in the world

The cable-stayed bridge to Russky Island across the Eastern Bosporus Strait is being built as part of Vladivostok's preparation program for the 2012 APEC summit. It will connect the mainland and island parts of Vladivostok.

The cable-stayed bridge will become world record for the length of the central span- 1,104 meters and the length of the cables - 580 meters. The height above the water surface is 70 meters. The height of the pylons is 324 meters.

The bridge will open for traffic in July 2012, and in September Russky Island will host the delegates of the Asia-Pacific Economic Cooperation Organization summit:

The total length of the bridge is 1885.5 meters, of which 1104 meters are the central span:

The width of the carriageway is 24 m. They will accommodate 4 traffic lanes (2 in each direction):

For the construction of the M6 pylon on the Nazimov Peninsula, an artificial peninsula was filled, from which wells were drilled for the supports. The total volume of rocky and loose soil moved during the construction of technological sites is 1.5 million cubic meters. (Note pylons are large-section pillars supporting the main (bearing) cables in suspension bridges):

At the base of each pylon there are 120 bored piles with a diameter of 2 meters. Piles with a metal shell under the M7 pylon go deep to the mark of 46 meters. On the Nazimov Peninsula maximum depth occurrence of reinforced concrete piles - 77 meters:

Approximately 20,000 cubic meters of concrete and about 3,000 tons of steel structures were required to build each pylon foundation. Tensor sensors are built into the foundation to monitor the state of this colossal structure.

The height of the pylon is 324 meters, which is commensurate with the height of a 90-story building (pay attention to the heights of the cranes on the right):

Delivery of builders to the pylon is carried out by passenger-and-freight lifts. The photo shows a German GEDA lift with a lifting capacity of 2 tons, which allows you to simultaneously transport up to 24 people. Lifting speed is 65 m/min:

The builders worked in extreme weather conditions . Wind speed reaches 36 meters per second, storm wind raises waves up to six meters, ice thickness reaches 70 centimeters. The temperature in winter drops below minus 36 degrees, and in summer it rises to plus 37.

View from a Potain MD 1100 tower crane 348 meters from the ground to this mark. As I was told, this moment, This the highest tower crane in Russia. The solution to such a height was supplied by special concrete pumps.

Lifting height - 335 m, boom length - 60 meters:

Crane Potain MDT 368 (France). Maximum lifting capacity - 16 tons, lifting height - 328.7 m, boom length - 40 meters:

Sections for the installation of the central span were delivered by barges to the assembly site and lifted by cranes to a 76-meter mark, where the cables were docked and fastened.

On the night of April 12, 2012, the builders completed the installation of the final locking panel of the span, which connected the shores of the Eastern Bosphorus Strait.

More than 300 people worked on docking the last panel.

On the bridge across the Eastern Bosphorus Strait, an improved system of cables with a denser arrangement of strands in the shell is used. The weight of the cable system is 3720 tons, the total length of the cables is more than 54 kilometers:

The shrouds consist of parallel, individually corrosion-protected strands, the number of which varies from 13 to 85:

Each such strand consists of seven wires covered with a high-density polyethylene sheath:

The shroud is made of two layers: the inner one is black, made of high-density polyethylene, the outer one is thinner, painted in the colors of the Russian flag:

The estimated service life of the shrouds is at least 100 years:

"Heart of the Bridge":

View from Cape Pospelov:

The Russian Bridge in Vladivostok is cable-stayed and connects the Nazimov Peninsula and Cape Novosilsky on the Russian Island, separated by the East Bosporus Strait. The bridge appeared as part of the APEC summit in 2012. The Russian bridge is complex and unique object throughout the practice of bridge building in Russia and the world.

Construction

The construction of the Russian bridge in Vladivostok began in September 2008, although the question of its construction arose at the beginning of the twentieth century. In 1939, the first draft was drawn up, in the 1960s, the second. But both remained unfulfilled. And only in 2008 the final design of the cable-stayed bridge was approved.

During the construction of the bridge, different positions were expressed regarding the expediency of its appearance. Some said that the work was not economically justified, since only five thousand people live on Russky Island. Others insisted that the construction of a bridge to Russky Island would be an impetus for the development of the island, the creation of large economic and cultural centers.

Description

The Russian bridge is one of the most grandiose in the world. One of the reasons for this is that the length of the bridge in Vladivostok on Russky Island – over three kilometers. The roadbed of the structure is supported by diagonal cables. They, in turn, are attached to two pylons, each reaching a height of 324 meters.

The entire structure weighs 23,000 tons. Its spans reach a kilometer. From the top of the bridge, you can see stretched cables painted in the color of the Russian flag. Lanterns are installed along the railings. At the descent from the bridge, one can observe cannons - the remains of the Novosiltsevskaya battery.

Hidden inside each pylon are ladders that lead to viewing platforms, but they are only available to staff watching the bridge, and only occasionally to photographers. From a height of 300 meters, a breathtaking view opens up: endless Pacific Ocean and below Vladivostok in barely noticeable outlines

Technical features

The cable-stayed system of the bridge across the Eastern Bosporus was designed by the best engineers in Russia and abroad. The shrouds consist of 13 to 85 parallel strands, each individually protected against corrosion. The shell is made of two layers: the inner one is made of dense polyethylene, the outer one is thinner.

The decorative shell has a spiral collar - it provides protection against vibrations generated during the simultaneous action of rain and wind.

The Russian bridge was built under conditions strong winds, humid climate and sudden changes in temperature. As a result, the cables, thanks to special steel, are able to withstand the temperature range from -40 to +40 degrees, and their service life is up to one hundred years. The aerodynamic section of the structure makes it resistant even to squally winds, which often happen in Vladivostok.

Movement

The bridge to Russky Island allows residents to travel there for the weekend. The building is designed for passenger transport and small trucks.

There are four traffic lanes on the roadway - two in both directions. Drivers who find themselves at a height of 70 meters are breathtaking from the water surface extending below and the shrouds hanging from above. Pedestrians are prohibited from entering the bridge.

Lighting

Lighting equipment for the bridge to Russky Island was completed in early 2013. The main task of the lighting is to create the illusion of a bridge floating in the air and at the same time emphasize its main elements - giant pillars and shrouds painted in the colors of the Russian flag.

Lighting equipment is fixed in such a way as not to create difficulties during operation. Lighting not only highlights the bridge, but also noticeably transforms appearance during the dark hours of the day.

Bridge for tourists

Today, tourists often come to Russky Island to look at the remains of the Novosiltseva Battery and the Vladivostok Fortress. The bridge itself is a landmark of the city. Everyone should drive along it at least once to Russky Island in order to get an unforgettable experience. It is very interesting to go to the island when it is foggy there - there is a feeling that you are entering a fairy tale. At night, the bridge is especially beautiful - lights and lights are on.

For the construction of one of the pylons on the Nazimov Peninsula, an artificial peninsula was arranged, from which wells were drilled for supports.
The construction of the bridge cost the federal budget almost 34 billion rubles.
In the list of the most high bridges The Russian Bridge is the second largest bridge in the world, second only to the Millau Viaduct in France.
Two years before the opening of the bridge, its official website began its work, which is still being updated.
The Russian Bridge, as one of the most beautiful cable-stayed bridges, has become a symbol of the Russian Student Spring 2015 festival.

As folk wisdom says, good man gets used quickly. Today it is hard to imagine that a year ago it was only possible to get to Russky Island by ferry. The trip took from 40 minutes to an hour and a half, depending on the destination. Today, the journey has been reduced to 5-10 minutes, and all thanks to the implementation of a unique project - the construction of a cable-stayed bridge connecting Russky Island with the mainland.

How it all began

Although the idea of creating a bridge to Russky Island (or rather, then still cable car) through the East Bosphorus was born in 1939, construction began only in 2008, and then by chance. Popular rumor says that the Minister of Economy German Gref and the former governor of Primorye Sergey Darkin were returning somehow from the next summit in Kuala Lumpur. And, flying over Russky Island, Gref dropped the phrase, they say, let the APEC-2012 Summit be held here! But how will the heads of state get there? Then they remembered the project of the last century.

True or not, but the bridge was built, and what a bridge! Describing it, one has to use the word “most” more than once - this is one of the largest cable-stayed bridges in the world with the longest central span and cables, as well as the highest pylon. According to the World Real Estate Portal, the bridge was recognized as the most significant architectural project in Russia in 2012.

Technical features

Bridge length - 1885.53 m
The length of the central span (from one pylon to another) - 1104 m
Bridge clearance (free space under the bridge) - 70 m
The height of the pylons - 324 m
The longest cable - 579.83 m

Building around the world

The cable-stayed system was designed as part of the joint work of many of the best engineers in Russia and abroad. For example, the French company Freyssinet developed a system of shrouds, similar, as it accurately noted " Russian newspaper”, to the strings of a giant harp - harps for ocean winds.

For the first time in the world, a cable-stayed bridge was built in conditions of such temperature fluctuations, strong winds and a humid climate. As a result, thanks to special steel, the cables can withstand the temperature range from -40 to +40, and their service life is up to 100 years! The aerodynamic section of the span makes the bridge resistant even to squally winds, which Vladivostok is so famous for.

First steps

The bridge was built simultaneously from two parts of the land - from the Russian Island and the mainland. April 12, 2012 happened historical event- docking of panels in the center of the bridge. On July 2, construction equipment passed over the bridge for the first time, then it was tested by cyclists, and on August 1, 2012, vehicular traffic was officially opened.

A month later, the bridge officially received a name: according to the results of the popular vote, it was dubbed the Russian Bridge.

For the past year, the bridge has been connecting Russkiy with the mainland. The brook of curious car enthusiasts who come to look at the changed landscapes of Russky Island has gradually turned into a powerful stream. Among those traveling to Russian and back, there are now students and employees of the Far Eastern Federal University, residents of the Russian Island and vacationers. And although the latter often leave behind mountains of garbage, the former, until recently, had problems with public transport, the population of Vladivostok and its environs agrees on one thing: the bridge is a blessing, and now no one understands how we used to live without it.

August 1, 2012 there was a significant event in the history of the Far East region of our country. On this day, the Russian Bridge (Vladivostok) was put into operation, the photo of which immediately graced the pages of leading domestic and foreign publications. And this did not surprise anyone, since long before the opening ceremony, many world media called the construction of this structure one of the most grandiose projects 21st century.

Story

It was decided to open the Russian bridge for traffic by the time the APEC Summit began, which was supposed to be held on the island of the same name. The construction of the facility began in the second half of 2008 and took four years to complete. However, the idea of building an object arose many decades before, and more than once. During the 20th century, two projects were developed with an interval of almost 25 years, but neither of the presented developments proved to be viable.

In 2007, new options were proposed. Among the 10 architectural and engineering works presented by the leading design bureaus our country, experts have identified original design cable-stayed bridge, although the possibility of erecting a suspension bridge was previously considered.

Foreign specialists and the best Russian engineering organizations actively participated in the work on the project.

USK Most became the general contractor for the construction, and the total amount of the contract amounted to 32.2 billion rubles. As for the supervision of the project, it was entrusted to V. Kurepin.

The new bridge was built at an accelerated pace simultaneously from the mainland side and from the coast of the island. Two teams of builders were moving towards each other, which met on April 12, 2012.

A month after the opening, the object received official name- Russian bridge. Vladivostok has acquired a new attraction, which today is considered the main architectural symbol of the city.

architectural features

Thanks to a span of 1104 m, the Russian Bridge is the pride and the largest object among similar ones in the world. The whole structure rests on the guys, which are strong cables. They are fixed on poles - pylons with the help of fasteners. The height of the Russian bridge in Vladivostok is 321 m, the distance between the vaults and the water surface is 70 m. This circumstance allows heavy ships to freely ply under it.

The load on the pylons of the Russian Bridge is evenly distributed. For the construction of each of the pillars, 9,000 cubic meters of high-quality concrete were used. One pylon could accommodate a residential microdistrict, and there are two such supports near the bridge.

The Russian Bridge is 1,885.5 meters long and weighs 23,000 tons. equals 24 meters (four lanes).

Bridge maintenance

The state of the structure is constantly monitored by a team of technicians and meteorologists. The specialists serving the bridge climb to a height of 300 meters along the stairs arranged inside each pylon. Occasionally, these premises are allowed to visit journalists and professional photographers. Bridge weather, wind direction, visibility, waves sea waves monitored for timely action.

An observation deck is equipped at the congress. It offers an amazing view of the endless Pacific expanse.

Construction features

Many experts call the Russian Bridge unique, and not only because of its length. The very construction of such a structure in the climate of Primorye can be considered unusual. High humidity, frequent squally winds, significant temperature differences created big problems and forced architects and engineers to look for extraordinary solutions. for the Russian Bridge was developed by French scientists who proposed the use of a special steel composition with a long service life (up to 100 years), at temperatures from -40 ºС in winter to +40 ºС in summer. In addition, the design was created taking into account the requirement of increased aerodynamic stability.

The value of the structure

The Russian Bridge plays an important role in the life of Vladivostok. It is of great economic and political importance, and also provides road links between the mainland and insular parts cities. At the same time, those traveling to Russky Island should remember that military bases have been located there for more than a century, and you can accidentally get into the territory, the entrance to which is prohibited for the inhabitants.

The administration of the region plans in the near future to place modern manufacturing enterprises, hotels, sports facilities, museums and attractions, residential neighborhoods and educational centers on Russky Island. Thus, with the commissioning of the bridge, broad prospects for investment in new housing construction and the creation of infrastructure facilities have opened up. It has also become the main highway for FEFU students to get to their new campus on Russky Island. At the moment, hostels are already operating there, in which up to 11,000 students can simultaneously live. In addition, there are several academic buildings, a high-rise Student Center building, and many sports facilities on the campus.

Directions

Unfortunately, you won't be able to walk across the bridge. It is intended only for the movement of public and private vehicles, and today it is considered the fastest and most convenient road from the main part of the city of Vladivostok to the historical one. However, even for drivers and passengers of cars, the passage on the bridge causes delight and admiration, as they find themselves at a height of 70 meters above the water surface.

Excursions

The Russian Bridge is often used today as a highway, along which the residents of Vladivostok go to the island of the same name on weekends. There is the historical part of the city, and the ruins of an old fortress have been preserved. In addition, there are cannons at the descent from the Russian Bridge. They once belonged to the Novosiltsevskaya Battery, built in 1901.

Some Vladivostok residents go to Russky Island in the summer to organize picnics and to sunbathe and swim. In addition, some travel agencies organize sightseeing tours, including inspection of the famous bridges of the city. Their program necessarily includes a visit to the islands in Peter the Great Bay.

If you have a chance to visit Vladivostok, be sure to check out the Russian Bridge. It will surely impress you with its size and power. This building is especially beautiful in the evening, in the lights of decorative lighting, so many travelers prefer to climb the observation decks after sunset.

The cable-stayed bridge across the Bosphorus-East Strait in Vladivostok took tenth place in the ranking of the most interesting tourist spots Russia according to the international Internet service TripAdvisor, reports Lenta.ru.

The Russian Bridge was competed with the sights of Moscow and St. Petersburg, as well as their suburbs. In addition, the Kazan Kremlin took the seventh place. Vladivostok Bridge took the tenth place in the rating.

The winners were determined using an algorithm that takes into account the quality and quantity of reviews of attractions in different countries left on TripAdvisor in the previous 12 months.

Russian bridge- a cable-stayed bridge in Vladivostok across the East Bosporus, connects the Nazimov Peninsula with Cape Novosilsky on Russky Island. Construction began on September 3, 2008 as part of the city's preparations for the 2012 APEC summit. The second highest bridge in the world, the height is 324 meters. At the time of its creation, it had the largest span in the world among cable-stayed bridges, 1104 meters long.

Minister of Transport of the Russian Federation Igor Levitin described the bridge to Russky Island as the most unique and complex facility not only in preparation for the APEC summit, but also in the entire practice of bridge building in Russia and in the world.

The issue of building a bridge to Russky Island was raised in the first half of the 20th century. The first project was completed in 1939, the second - in the 1960s. Neither project was ever carried out. At the beginning of October 2007, NPO Mostovik won a tender for the design of a bridge crossing to Russky Island. The main partner of the association in the implementation design work became the largest Russian design organization CJSC "Institute Giprostroymost St. Petersburg", a number of Russian and foreign scientific companies were also involved in the work. Among them are Cowi A/S (Denmark), Primorgrazhdanproekt, Primortisiz, JSC DNIIMF, NPO Hydrotex and others. The development cost 643 million rubles and was completed in less than six months in March 2008. In the course of the work, more than 10 different options for a bridge crossing were considered, among which were projects of both cable-stayed and suspension bridges.

In May 2008, the proposed design of the cable-stayed bridge was approved by the Federal State Institution "Glavgosexpertiza of Russia" and recommended for approval by the customer - the Primorsky Territory Administration. The general contractor for the construction - JSC "USK Most" - bypassing the tender procedure, was determined on August 31, 2008 by Decree of the President of the Russian Federation No. 1277. The total amount of the contract amounted to 32.2 billion rubles. The main subcontractors were OAO SK MOST and OOO NPO Mostovik. The object was handed over on July 2, 2012. Ch. project engineer - V. M. Kurepin.
