Abstract
A tunnel is built in successive sections by a machine suitable for operating at the surface and in immersion that is displaced in the water on the sub-sea soil. This machine includes a fluid-tight working space (6) for accommodating the personnel and equipment required for construction. Further, this space has a rearward-facing opening for building and erecting a section at the rear of the machine. The forward section of the machine includes a ballastable chamber (7) which prepares and grades the soil for erection of a section.
