Abstract

The barrier for protecting the surface of water against wave motion, particularly in harbour protection, comprises a partly submerged permeable structure consisting of mutually spaced parallel grids, formed from elongated elements opposing the wave motion. At least part of the external surface of these elements is of helical form and advantageously is formed from a strip with its lateral edge wound helically onto a cylindrical core. Preferably each grid consists of parallel vertical elements (10, 11), of metal or plastics. Each element has an endless strip (14, 15) fixed edgewise on a solid or tubular cylindrical core (12, 13). Adjacent elements have the sense of the helic opposite to one another so that a current of water directed towards the grid perpendicularly to the plane will be broken up into stream directed axially up and down (16) and radially outwards (17, 18).
