Abstract

The new railway bridge over the Nosická dam is a part of the complex modernization of the railway corridor from Púchov to Žilina. Our company participated on the project using a wide variety of special foundation techniques on artificial islands for piers P6, P5, P4 and P3 and the pillar foundations. We applied the many years of experience gained by our company through working on projects involving water. Bored piles, as well as vibrated sheet piles, welding and assemblage work have all been carried out from a floating pontoon platform and also there was jet grouting applied to stabilize embankments. At the same time we provided active assistance with temporary floating bridges and platforms for the kind of transfer on water required by our client.

Highlights

  • As part of the first phase of the modernization of the Púchov - Žilina railway line for speeds of up to 160 km/h on the interstation section Púchov - Považská Bystrica, our company has been carrying out special foundation work on structure SO 44.33.21.1 on a new railway bridge over the Nosická dam going back to autumn 2016 - see Fig. 1

  • It connects to SO 44.33.21.2 - the bridge under the double-track railway line, which transfers to the road III / 5171 from Milochov to Považská Bystrica

  • The result was that this geological layer was generally higher than had been assumed, which led to an acceptable reduction in the length of the sheet piles
