II/104 Bridge over the Vltava river in Davle, reg. No. 104-001

The bridge in Davle municipality is situated at the confluence of the Vltava and Sázava rivers.

Construction period: 2017/09 - 2018/10
Total value of the contract: 66 151 092 CZK excluding VAT

The bridge leads the II/104 road via II/102 road, twice the local roads (Jílovská Street), the Vltava river and a railway line connecting the village of Jílové near Prague and the town of Davle. The supporting structure of the bridge is made up of a continuous beam of five fields, the first four of which are made of a chamber beam and the last, fifth one, is designed as a two-ramp structure.
Based on an extraordinary inspection in 2014, the under construction of the bridge was rated grade IV and the supporting frame grade VI (very poor). The aim of the reconstruction was therefore to improve the technical condition; construction of new supports, replacement of bridge seals and bearings as well as execution of a new joining plate, followed by replacement of the entire upper part of the bridge and accessories, rehabilitation of the supporting structure and modification of the internal parts of the chamber beam.
The extent of the work of the tender documents was determined on the basis of an extraordinary inspection and diagnosis of only one support, so implementation of a number of additional diagnostics was requested. They revealed a strong occurrence of alkaline-silica reaction in all concrete structures and very low resistance of concrete to chemical de-icing agents and watertightness. For this reason, the abutments had to be replaced almost completely, including replacement of several non-functional bearings, and the remediation had to be solved as waterproof and vapor-permeable to prevent the ingress of moisture into the structure.
