Being commissioned in October last year by Implenia-Demathieu Bard Construction from Raisin station, TBM Marie-Th\u00e9r\u00e8se de Villeneuve-Arifat was to dig the 3.8km tunnel for Lot 3 and it has completed its mission on Lot 3 of the Toulouse metro Line C at the first section.<\/p>\n
The first drive to Bonnefoy station was 872m long and the TBM installed 526 rings.<\/p>\n
According to Implenia: “The tight space in the launch shaft meant a phased assembly was required for the seven trailers of the 142m-long machine. It was in January 2025 that this formidable machine was able to reach its cruising speed once all the equipment and services were installed and operational.”<\/p>\n
The next destination of this variable density TBM is due to be the future Matabiau Gare station where it is expected to arrive this summer.<\/p>\n
Linking Colomiers on the western side of Toulouse, to Lab\u00e8ge in the south, the 27km-long Line C will reduce journey times of 20 minutes.<\/p>\n
Excavation of a 3.8km-long tunnel in a dense urban environment as well as civil engineering works for the construction of four underground stations at a depth of 24-39m and three ventilation shafts, are the contents of Lot 3.<\/p>\n","protected":false},"excerpt":{"rendered":"
