ROAD BRIDGE OVER THE DANUBE IN NOVI SAD – SERBIA "Varadinski most"

 

ROAD FLOATING BRIDGE OVER THE DANUBE IN NOVI SAD – SERBIA

A steel continuous beam across three plains spans the Danube using the piers of the destroyed steel trussed bridge. Sub-assembly of two segments, 111.7m long each and the intermediate one 81.4m long is performed on the river bank. Erection of the structure is performed by the cantilever method by means of a vessel with the portal hydraulic cranes. The overall length of the bridge is 304.8m. Fieldwork lasted 105 calendar days. Structure of the bridge consists of six vessels – barges intended for river barge and push tug assemblies. They are strenghtened and adjusted by an addtional structure to bear the two-way road and foot traffic. Four barges are placed perpendicular to the river flow and anchoraged to concrete piers of the old railway bridge with the ability to permit passage of ships and ice. The bridge had been used until the Bridge of Sloboda is completed. It was removed on October 11, 2005. The bridge length with approach ramps was 369.60m. All work was completed in 60 calendar days.
   

SCAFFOLD ROAD RAILWAY BRIDGE OVER THE DANUBE IN NOVI SAD – SERBIA

 ROAD BRIDGE OVER THE RIVER VELIKA MORAVA AT MIJATOVAC – SERBIA
The bridge consists of six steel trusses of the simple beam system with a span of 36.0+4x72.0+102.0m. They are composed of the erecting and dismantling elements MD 88. These elements serve for rapid bridging the obstacles with the span up to 102m without the intermediate piers. The river piers are founded to the bored piles of 1.50m in diameter, braced by prefabricated reinforced concrete rings and pile helmets. Road and rail traffic flows by turns. The overall length of the bridge is 423.50m. All work was completed in 100 calendar days. The bridge is a prestressed structure across five plains of the continuous beam system.  The intermediate piers are erected on the foundations of the destroyed bridge and the coastal piers are adjusted. The pavement structure consists of two main longitudinal girders with cross girders and bridge deck. They are made as the prefabricated elements, 5.22m long, and then joined into prefabricated pieces with the maximal length of 20.40m. They are erected by the launching truss. Such a thought-out technological procedure enabled fast and economical erecting of the bridge. The overall length of the bridge is 275.60m.
   
ROAD BRIDGE OVER THE DANUBE AT BOGOJEVO – CROATIA ROAD BRIDGE OVER THE BOLJETINSKA RIVER
The bridge consists of two independent steel structures:
  • a continuous girder of a box cross-section is of variable height and with a span of 100+150+100m.
  • a continuous girder of a box cross-section is of constant height and with a span of 60x3x75m.
The upper chords of these structures is an orthotropic deck (plate). The structure erection is performed by a floating crane. The cantilever procedure on principle of cantilever erection is applied to the great span, and temporary supports are used for other spans. Two piers on navigation route are founded to caissons, and the others to HW piles with 120mm diameter. The overall length of the bridge is 670m.
 At a height of 54m above the river bed, Boljetinska river canyon is spanned by two reinforced concrete arches with a span of 92m. They are built on the steel three-hinged arch falsework. The road surface is a continuous beam over seven plains with a span of 16 m each. The arch abutments and piers on the river banks are founded to a limestone rock.

SCAFFOLD ROAD RAILWAY BRIDGE OVER THE DANUBE IN NOVI SAD –SERBIA HIGHWAY   E – 75 STATE BORDER (HORGOS) - SUBOTICA - FEKETIC
Two reinforced concrete arches with spans of 211m and 165.75m, as per construction method, presented the unique solution in the world. A scaffolding made of prefabricated reinforced concrete elements was constructed by cantilever procedure for the first time in the world for the purpose of concreting the big arch. Until joining in the apex, cantilevers were held by cables which were anchored into the arch abutments through the temporary pylons. Very high percentage of prefabricated reinforced concrete parts of the bridge which were permanently incorporated in suspended carriageway on the bridge was used for the first time in our country. Those are: hangers, transversal girders, bracings and footpath elements. Arch abutments were constructed by caisson method of which the middle one has the surface of 838m2. The total length of the bridge amounts 466.45m. .  On the 71km State border - Feketic stretch of the International Highway E - 75, 30 (thirty) Bridges Overpasses, in total length of 2,000m, have been constructed.  All Project were founded on piles, foundations and abutment supporting beams casted in situ, and piers, piers supporting beams and prestressed girders executed as precast elements. All spans of Overpasses are 26m.
