Abstract

L'invention porte sur un bloc de récif pour poissons et d'absorption des vagues, lequel bloc est apte à la fois aux fonctions de récif pour poissons et d'absorption des vagues. Selon le bloc de récif pour poissons et d'absorption des vagues de la présente invention, qui est fermement relié sous l'eau par un ajustement et une accumulation de couches, un corps de bâti supérieur (12) et un corps de bâti inférieur (22) où des trous traversants (10, 11) sont formés presque dans un centre de ces deux derniers sont intégrés entre eux par l'utilisation d'un cylindre ou d'un corps en forme de plaque, et une pluralité de corps saillants (32, 33) font saillie à partir d'une partie de coin de chacun des corps de bâti (21, 22). Les corps saillants (33, 32) d'une pluralité d'autres blocs de récif pour poissons et d'absorption des vagues peuvent être insérés dans les trous traversants (10, 11) de chacun des corps de bâti (21, 22), et les corps saillants (32, 33) de chacun des corps de bâti (21, 22) peuvent être insérés dans les trous traversants (11, 10) d'un autre bloc de récif pour poissons et d'absorption des vagues.
