Emptiness forming tubes “HELCOR Standard D1300“: total length of line without cones – 1913.5 m;
Pre-stressed cables: 262t;
31 strand fiber anchors: 44 pcs.;
31 strands of fibers fixed connections: 66 pcs.;
27 strand fiber anchors: 132 pcs.
Overlay was concreted and tensioned in 7 phases. Considering that 2 separate overlays were installed, installation phases rises to 14. 31 strand fiber tension force reaches 6.7 MN (670 tons).
Work was supervised by the staff of JSC “ViaCon Baltic” technical department. Lightening pipe and cable installation took about a year to finish.
Lightening pipes and pre-stressed ropes installed in bridge overlay construction was the most rational and cost-effective solution. In this way, the viaduct was built quickly, without causing any additional problems for users. Additionally, after starting traffic road user safety was ensured.
