All the works were executed in the river bed filled with water - to avoid future barrier under flow, the net was extra ballasted and the bottom with precast concrete blocks

Situación inicial

The road connecting Topoloveni with the A1 Highway became compromised when the bridge foundations, supporting the highway, over the Arges River, began to erode.  Initally a check dam was planned to prevent further damage to the bridge.

Descripción

To protect the bridge foundations, Geobrugg proposed and designed an alternative solution to a massive and heavy concrete check dam.  With our special design, using Geobrugg debris flow barriers and Geobrugg DEBFLOW dimensioning software, two flexible check dams were designed and installed. Thanks to this unique technology, a new diversion channel was not required.

The installed barriers were filled with rock blocks. By changing the river's hydraulic gradient and slowing down the flow of the river, further erosion of the bridge foundations was prevented.
