Visit to the construction site of the Line 16 station in Chelles
with students from the École Nationale des Ponts et Chaussées
For Terrasol, passing on knowledge is essential to preparing future generations for the challenges of geotechnical engineering! Yesterday, students from the École nationale des ponts et chaussées had the opportunity to experience the reality of the field by visiting the construction site of the Line 16 station in Chelles.
Accompanied by Fabien Binet, a geological expert, they learnt about terrasol’s role as project management consultant on this major project.
The geometry of Chelles station is a double-lobe structure with diaphragm walls capable of withstanding high water pressure. To optimise the schedule, the tunnel boring machine passed through the station before its excavation.
On the agenda for this morning:
– Introduction of the speakers and site supervisors,
– A guided tour of the ongoing construction site, focusing on:
🔹 Diaphragm walls anchored at a depth of 60 metres,
🔹 The struts installed beneath the foundation slab to counteract water
pressure, 🔹 The various construction methods employed,
🔹 The importance of collaboration between project stakeholders.
Thank you to Egis and the Société des grands projets for organising this visit, as well as to the École nationale des ponts et chaussées for their trust, to the students for their enthusiasm, and to Fabien Binet, Benjamin Grenault and Yoanna GENOUEL for their commitment to sharing their knowledge!
