Method for installing a device for protection against the swell, and device resulting from the implementation of this method

摘要

The device comprises at least one support (2; 2'; 2''; 2''', 2'''') fixed to a predetermined site on a seabed, and a caisson (1; 1', 1'') comprising means allowing it to be floated so that it can be transported as far as the predetermined site, and means (12, 13; 7; 7') for raising the caisson onto the support so that the caisson is then at least partially submerged in a predetermined position with respect to the surface of the water. The caisson (1) is centred on the support (2'') by guides (13) interacting with spindles (12) secured to the support. It is made to bear on the support in a gravity fashion by the addition of ballast. Application to the protection of a coastal site or construction. <IMAGE>
