Русский мост

The bridge crossing over the Eastern Bosphorus Strait on the Russky Island has joined the mainland and island parts of Vladivostok. Despite of the unique design and adverse climatic conditions, the bridge was built in just 43 months, instead of 63 in accordance with the scheduled plan.

The approaches to the bridge are represented by overpasses with total length of 900 meters with maximum height of pylons 40m, and roadway width of 21 m. The curve in terms of the trajectory of sloping ramps and super elevated corners in the plane were complicating the choice of formwork system for construction of monolithic slabs of the carriageway. STALFORM Int’s specialists had developed the most suitable technologies and equipment for safe concreting and maintenance of composite reinforced concrete spans of overpasses and formwork systems for construction of complex anchor support M12 with a vaulted collar - beam.

Requirements to the formwork

• economical technology — for accelerated construction of concrete steel-reinforced concrete spans with a variable geometry
• minimum load on the spans
• reliable operation under extreme weather conditions
• safety of work at height, including during gale force winds and low temperatures

Solutions

• STALFORM’s rolling formwork units with adaptable geometry - for concreting the roadway of the overpasses
• formwork of aluminum alloy — in order to reduce the load on spans and for unfailing operation at low temperatures
• arched forming unit and large-panel forming system MEGAFORM ALanchor pylon M12
• STALFORM’s suspension system – for technological servicing of construction operation on the channel span
• on-site engineering support during the entire period of operation of the equipment
• cost-effective transportation and warehousing of dismountable systems and units made of light aluminum alloys
