Abstract

For use as a structural unit in a variety of coastal and other civil engineering works, a formed block or pile of concrete or other material is provided which comprises a conical body and a cylindrical leg extending coaxially from the vertex of the body. Offshore breakwaters can be built by laying a multiplicity of such funnel-shaped blocks into one or, usually, two or more superposed horizontal layers, with each block having its leg oriented downwardly. At least the lowermost layer of blocks are buried directly into the seabed, and the upper layer or layers of blocks are installed with or without use of a support structure serving to prop up each block.
