Launch of the first TBM for the Grand Paris Express


On the 03.02.2018 the first TBM for the Grand Paris Express line will be named and launched at Champigny-sur-Marne (Ile de France) at around 5.30 pm. A decisive step in the progress of the works of the new subway, whose first line, the 15 South, will connect Pont de Sevres to Noisy - Champs.

The largest crane in Europe will drop the TBM’s shield into the shaft, which will be 20 m deep and located in the departmental park of the Plateau. The TBM, manufactured by Herrenknecht, is 100 m long and 10 m wide. The TBM, once assembled, will begin to excavate the tunnel (2.2 km) connecting the Champigny operations centre, to the main tunnel of the South Line 15 at Villiers-sur-Marne. The expected average advance will be  12 m / day. The 170 km Grand Paris Express project involves the use of 30 TBMs: a record in Europe.

The launch event is open to everyone. Click here and fr/127for the tunnelbuilder archive. Connect to https://www.societedugrandparis.fr. 05/18.
