“ELEMENTO PROTETOR PARA UM QUEBRA-MAR OU CONSTRUÇÃO DE RETENÇÃO DE ONDA E MÉTODO E CONTRAVENTO PARA A SUA PRODUÇÃO”

摘要

A protective element for a breakwater or wave-retarding construction comprises a body that has at least two opposing projections. The projections are on either side of a flat base and extend transversely thereto. The periphery of the base is non-circular, so that rolling of the protective element under the influence of the beating of the waves is resisted.
