Engineering News STALFORMWas completed incremental launching of spans on the even side of the Schelkovskoye highway’s overpass (destination towards the region). It should be noted that the six-lane 547m overpass on the main course of the Schelkovskoe highway at the intersection of Uralskaya and and the 9th Parkovaya streets, was constructed by cyclic incremental launching method, without stopping traffic.
The prestressed, reinforced concrete spans were preliminary concreted on the stocks, following which the finished portions were pushed over to supports. During construction process the length of pours has been increased from 20 to 40 m, and the all-metal formwork was replaced by a universal formwork system FORMEC, which was furnished with a feature for convenient adjustment at the place.
According to General Contractor, Corporation «Transstroi», the doubling of length of pours, made it possible to reduce the concreting cycle and incremental launching of the span by 20 days. It is expected that after the reconstruction, the roads capacity of the road at this segment of the Shchelkovoe highway will increase by 30%.
