MODULARE KÜNSTLICHE RIFFANLAGE

The invention concerns a type of artificial reef both simple and aesthetic, and its method of installation. The reefs consist in a juxtaposition of generally hexagonal towers a few meters in diameter. Each tower can be assembled in situ based on two types of simple concrete modules: hexagonal plate modules (1) designed to be set horizontally and comprising one or more vertical through holes, and on the periphery at least a horizontal surface of recesses and protuberances enabling them to be nested; wall modules forming braces, shaped like rectangular parallelepipeds (2), designed to be placed vertically and comprising on one of their faces a recess and on the opposite face a male protuberance, capable of being nested into other protuberances and/or recesses of other wall and plate modules (1) which they separate. The modules are assembled to one another by one or more metal tie-rods, tubes or lock rings.
