Situation The road connecting Topoloveni with the A1 Highway became compromisedwhen the bridge foundations, supporting the highway, over the Arges River,began to erode. Initally a check dam was planned to prevent further damage tothe bridge.
Description To protect the bridge foundations, Geobrugg proposed and designed analternative solution to a massive and heavy concrete check dam. With our specialdesign, using Geobrugg debris flow barriers and Geobrugg DEBFLOWdimensioning 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'shydraulic gradient and slowing down the flow of the river, further erosion of thebridge foundations was prevented.

Two debris flow barriers, VX-140 and VX160, servingtogether as check dam at the Arges River - visible riverflow influence
Site situation prior to installation - visible heavy erosionand bridge piles exposure
Original protection using gabions unfortunately did notwork out

All the works were executed in the river bed filled withwater - to avoid future barrier under flow, the net wasextra ballasted and the bottom with precast concreteblocks
Second barrier ready to be filled out - visible river bedballasting using precast concrete blocks

Closer look at the final installation - both debris flowbarriers, VX-140 and VX160, filled and covered with rocks
Unique solution after installation - visible water flowslowing effect
One year after installation - Geobrugg's debris flowbarriers are designed as permanent solutions
