Construction of а cable-stayed bridge to the Russky Island across the Eastern Bosphorus Strait in Vladivostok http://rusbridge.net Fri, 03 Feb 2012 06:33:57 +0000 en hourly 1 http://wordpress.org/?v=3.0 Over 260 Thousand Cubic Meters of Concrete Mix Poured in the Structures of the Bridge to the Russky Island http://rusbridge.net/2012/02/over-260-thousand-cubic-meters-of-concrete-mix-poured-in-the-structures-of-the-bridge-to-the-russky-island/ http://rusbridge.net/2012/02/over-260-thousand-cubic-meters-of-concrete-mix-poured-in-the-structures-of-the-bridge-to-the-russky-island/#comments Fri, 03 Feb 2012 06:31:52 +0000 DenisK http://rusbridge.net/?p=1622 Over 260,000 cubic meters of high-grade concrete have been poured in the cast-in-place structures of the bridge to the Russky Island in Vladivostok. A total of 95% of the entire concreting work has been completed on both sides of the Eastern Bosphorus Strait.

Meanwhile the bridge stay cable and girder system is being installed strictly on schedule. A total of 130 stay cables that are 483-meters long have been already installed on both sides of the strait. They are currently tensioning the 34th pair of stay cables on the Nazimov Peninsula, and the builders have proceeded with installation of the 31st pair of stay cables on the Russky Island.

The total length of the opposed cantilever sections of the main span is now 852 meters which is more than 75% of its total 1,104-meter length. Over 18000 metric tons of steel structures of the bridge main steel stiffening girder have been installed, and the work is in full swing to lift paired panels No. 43-44 and No. 41-42 from the water to the design elevation on the Nazimov Peninsula side and on the Russky Island side, respectively.

Each stay cable is 359.5-meters long. The pair of stay cable that has been installed is the first on the Russky Island side that is colored white.

About two thirds of the total bridge stay cables have been already installed. A total of 14 pairs of red, blue, and white colored stay cables will be installed on each side of the strait.” The stay cable system of the bridge to the Russky Island will symbolize the national flag of Russia.

The white-jacketed stay cables are being installed on both sides of the strait: the bridge builders have installed the 29th pair of stay cables on the Russky Island and the tensioning of the 32nd pair of stay cables is about to be completed on the Nazimov Peninsula. The total length of the stay cables that have been already installed on the bridge is about 33 kilometers.

A total of 21,000 cubic meters of high-grade concrete mix have been supplied to the elevation of 70 meters to complete the anchor spans.

The movement joint between the viaduct section and the reinforced concrete stiffening girder is being installed on the Russky Island. The joint is 2.7-meters wide, and the total weight of the structures is 100 metric tons. The size is based on the total bridge length of 1,885.53 meters, with the world-record length of the span deck structure that is 1,104-meters long. The movement joints over the anchor pillars, M1 on the Nazimov Peninsula side and M12 on the Russky Island side, are also record breakers as they are the largest joints in the bridge building.

As a result of this operation, the cantilevered part of the steel stiffening girder on the Russky Island side extends now over a distance of 390 meters from the M7 Pylon centerline toward the mainland. A total of 414 meters of the span deck have been installed on the Nazimov Peninsula side where paired panel number 39-40 has been lifted to the elevation of 70 meters. The total length of the opposed cantilever sections of the main steel stiffening girder is now 804 meters or 72.8% of the total length of the 1104-meter long channel span of the bridge to the Russky Island.

According to the approved color pattern for the bridge to the Russky Island, the stay cable pair that has been installed is the first one of the stay cables which will be colored white.

“The Russky Bridge stay cable system will symbolize the national flag of Russia flying over the Eastern Bosphorus Strait,” explains Aleksey Baranov, Director of the OJSC USK MOST Branch in Vladivostok. “A total of 14 pairs of red, blue, and white colored stay cables will be installed on each side of the strait.” They are currently tensioning the 29th pair of stay cables on the Nazimov Peninsula, and the builders have proceeded with installation of the 26th pair of stay cables on the Russky Island. The total length of the stay cables of the bridge over the Eastern Bosphorus Straight is now over 27 kilometers.

The supercompact stay cables of the bridge to the Russky Island are second to none in the world in terms of both the length and design. The stay cables that are currently being installed are longer than 410 meters. The closing stay cables in the channel span will be 580-meters long, a new world record in bridge building. The expected service life of the supercompact stay cables of the bridge to the Russky Island is of 100 to 120 years.

The system is designed to lift water to the 350-meter elevation.


This system will fight fires using two methods: simply with water and with temperature-treated water. The latter method consumes a minimum quantity of water that is supplied at the temperature of +200°C under the pressure of 100 atmospheres. When water flows through a special spray nozzle at the end of the firefighting monitor a steam cloud with droplets of 10-50 µm in diameter is formed. Water in this state has many of its physical properties changed, and the man-made fog forms a film on the surface that was set on fire to lower the surface temperature to a significant extent.

When conventional firefighting technologies are used, as little as 10% of water is used directly for fire suppression, and the remaining 90% are just wasted. Everything goes the other way around when the temperature-activated water is used for fire suppression: As much as 90% of water is used purposefully and the water is not lost but rather stays in place as a cloud for almost 40 minutes. Therefore the new method consumes 10 times less water when fire is suppressed outdoors and 50-100 times less when fighting fire indoors.

The active fire suppression system has been installed on the right hand leg of M6 Pylon on the Nazimov Peninsula. The bridge builders, jointly with the designers with the Akva-Piro-Alyans Company, installed the special equipment and firefighting monitors on the self-lift shutter structures. With this arrangement, fire could be prevented simultaneously on both pylon legs. The innovative fire suppression system will be installed on M7 Pylon on the Russky Island shortly.

The unique heavy-lift high-rise cranes were ordered specifically for construction of the bridge over the east Bosphorus Strait. They have been telescoped by inserting additional tower sections with the help of hydraulic equipment. The giant cranes have been grown higher to catch up with the pylons to rise above the pylon legs.

The lifting cranes have now grown over 300 meters high for the first time in the Russian bridge building history. Sections No. 65 of M6 Pylon, which is now 292.9-meter high, have been concreted on the Nazimov Peninsula side. Sections No. 63 of M7 Pylon whose legs are now at the elevation of 283.9 meters above the sea level have been completed on the Russky Island side. The lifting crane cabs will finally rise above the Eiffel Tower to become 340-meters high by the time the construction work has been completed.
