Ligne 500 000 de Chartres à Bordeaux- Déblai du tunnel de la Ramade

 - Ligne 500 000 de Chartres à Bordeaux- Déblai du tunnel de la Ramade 2024

The TECCO system combined with hydro mulching perfectly stabilizes the railway embankment and prevents further traffic disruption

A coco revegetation mat is laid under the TECCO to keep the fine soil particles until the surface vegetation recovers

Situation

The railroad line 500 000 arrives in the Bordeaux urban area at Lormont and enters underground at the northern end of the Ramade tunnel. Before this tunnel’s entrance, the profile is excavated, with up to 15 meters high embankments. These embankments are made up of silt and sandy clay, generating landslides and repeatedly cutting the tracks.

Description

TECCO was chosen as the optimum solution for this stabilization work. Dimensioning during the execution phase made optimizing the facing with a TECCO G45/2 possible, which greatly facilitated installation rates with a maximum cost/quality ratio for this project. The hydro mulching operation allowed the stabilization solution to be ideally finalized.
