- the construction element 5 is prefabricated, that is to say that it is produced before the tunnel 1 is made. In other words, the construction element 5 is previously produced, then several construction elements 5 are assembled together so as to form a section 4 of the tunnel 1. Thus, it is avoided to achieve a damping coating by injection of material between a voussoir and the ground 3.
- the building element 5 incorporates before a compressible layer 7, and therefore has an integrated mechanical damping property.

- the initial distance Gi corresponds to the sum between the initial thickness E of the second layer 7, the thickness of the third protective layer 12, and the thickness of the free space F.
- the thickness E also depends on the compressibility of the devices 8.
- the devices 8 are coated with an adhesive film 11 for joining them to the first layer 6.
