The works on the construction of the Lot T2B for the new Line 15 south of the Paris Metro continue.

The tunnels interchange shaft called “Salengro” (1001P), which will guarantee the interchange between the Line 15 south (red) and the Line 15 east (orange), is now in its third and final phase with reference to the realization of the retaining structures.

The diaphragm walls, made with grab and trench cutter by our teams, have a thickness of 1500 mm and depth of up to 65m from the ground floor, for unitary concrete castings up to almost 700 m3.

The works are carried out by I.CO.P. together with Eiffage Fondations for Eiffage Genie Civil and Razel-Bec, Project Manager Systra and Client Societé du Grand Paris.
