Abstract[English]
The invention concerns to an innovative method for the construction of submerged tunnels, in which the tunnel is built out of the water and subsequently immersed and progressively placed in the trench prepared on the seabed without having to join segments of the external structure of the tunnel under the water level. This is in order to make their realization simpler and more efficient. The method allows the progressive laying of the tunnel, on a trench prepared for the purpose, exploiting the differential of the hydrostatic and gravitational forces that act in said laying phase on the tunnel itself and controlling it, also through the positioning of weights along it, to keep the stresses of the materials within the desired limits.[French]
L'invention concerne un procédé innovant pour la construction de tunnels immergés, selon lequel le tunnel est construit hors eau puis immergé et progressivement placé dans la tranchée préparée sur le fond marin sans avoir à joindre des segments de la structure externe du tunnel sous le niveau d'eau. Ceci rend leur réalisation plus simple et plus efficace. Le procédé permet la pose progressive du tunnel, sur une tranchée préparée à cet effet, par exploitation du différentiel des forces hydrostatiques et gravitationnelles qui agissent dans ladite phase de pose sur le tunnel lui-même et de le commander, également par positionnement du poids le long de celui-ci, pour maintenir les contraintes des matériaux dans les limites souhaitées.
