    摘要： The present invention relates to a thermally insulated pipe for the construction of underwater pipelines, characterized by being formed from prefabricated pipe portions welded together, each portion being constituted by two concentric tubes of different diameter which are connected together at their ends by means of special cylindrical pieces having a double T section which are welded to the two tubes in such a manner as to form between them an annular interspace which is filled with thermally insulating material.

    摘要： This invention provides a seismic joint for an underwater floating tunnel having: (a) a joint portion (i) having a transverse section essentially the same as that of the tunnel, (ii) being rigidly fastened to land at one end (A) thereof, and (iii) being elastically constrained to the tunnel at its other end (B) via a plurality of operably affixed means which performs an elastic function and a damping function; (b) a collar welded onto the external surface of the tunnel facing end (B) of the portion, said collar being capable of sliding on and along the external surface of the joint portion; and (c) a means for providing a water-tight seal between the internal surface of the collar and the external surface of the joint portion.
