LGV 58 Signal stations

Marne La Vallée - Valence Line

Contracting authority :          SNCF INFRAPOLE LGV SEE LYON

As part of the modernisation of the High Speed Line linking Marne-la-Vallée to Valence, the SNCF is planning to create new signalling stations.

Sol Solution was thus commissioned to carry out geotechnical missions for the preliminary design G2 AVP of 58 stations on the line. Each station has a ground area of 89 or 126 m² and will be installed on an equipped platform.

For 5 weeks, a drilling team travelled along the 485 kilometres of track to carry out the 58 soil surveys equipped with a GRIZZLY® and a light PANDA® penetrometer.

A total of 104 boreholes and 113 penetrometric tests were carried out at 5 metres or at refusal.
