Reconstruction of Bridge in km 2.089 on Děčín – Jedlová Line Festively Completed
Děčín, 29 May 2014 – The Railway Infrastructure Administration, state organisation festively completed the project “Reconstruction of Bridge in km 2.089 on Děčín – Jedlová Line“. This important construction which replaced the original provisional steel railway bridge construction over the Elbe River in Děčín is co-financed by the European Union under the Cohesion Fund through the Operational Programme Transport.
The construction is situated on the Děčín – Rumburk railway line in the section Děčín Main Station – Jedlová between railway stations Děčín Main Station and Děčín East. The bridge is located within the city of Děčín and leads the railway line over the Elbe River and its flood grounds at its confluence with Ploučnice River. The objective of the reconstruction was ensuring rail operation safety and reaching required technical and operational parameters by removing the current unsatisfactory temporary construction, installed in 1976 over an original stone substructure dating from 1868. The unsatisfactory construction being out of date now has been replaced by a new steel framed structure with a lower orthotropic bridge deck with continuous ballast.
The main part of construction works took place during rail operation closure from 18 September to 29 November 2013. During reconstruction, the bridge subsoil was saved; the original bridge pier caps were removed and replaced by new concrete ones. Bridge piers were strengthened by micropiles; exterior dry masonry on stone arches on bridge approach stone arches was removed and replaced by new transition slabs. During reconstruction, the line route was optimised including installing a continuous welded rail, at the same time the overhead contact line was adapted. The bridge reconstruction also necessitated dismantling a high-pressure gas duct as well as relocating navigation markings, signalling, safety and optical cables.
Construction works, especially on bridge arches embedded in the riverbed were considerably complicated by floods in June 2013. The first of them even damaged considerably provisional constructions already built up to that day. After water fell off and the building site was cleaned from alluvium, the construction was dismantled based on the construction manager’s and designer’s decision. Due to these unfavourable conditions it was necessary to accelerate the speed of construction. Assembling works on the bridge steel construction thus continued on all three newly built constructions simultaneously. Before putting the bridge into operation, a load testing was successfully carried out by two EDK 750 cranes with a total weight of 126 tonnes. The reconstructed section was put into testing operation on 29 November 2013.
Reconstruction of Bridge in km 2.089 on Děčín – Jedlová Line has been proposed to be co-funded by the European Union through the Cohesion Fund by a sum of 68.648,693 CZK. National resources were provided by the State Fund for Transport Infrastructure. Total investment costs of the construction amounted to 85.100,100 CZK (VAT excluded).
