Abstract (en)

An immersed tunnel of the type comprising a formwork structure (6), an underwater concrete casting (5) which externally surrounds said structure (6) and internal finishes (8), in which the mentioned formwork structure (6) consists of a plurality of open-ended segments (9, 12) allowing the entrance of water present at the laying site of said tunnel. In relation to the above-described known art, the tunnel of the invention offers the advantage of being able to be laid in an immersed state, i.e. directly in its place of installation. In this manner, all the traditional problems related to the dredging of the tunnel laying site are overcome.
