System for protecting beaches against marine erosion

摘要

A system for protecting a coast against marine erosion by means of barriers arranged at a distance from the coast, wherein each barrier (1) is composed of two fixed structures (2, 3) which are installed on the sea floor, a wall (8) being arranged between the structures and being supported therein and comprising two portions (6, 7) which can move with respect to a horizontal axis (C) which is immersed at an intermediate depth of the sea, and means (9, 12) for actuating such portions (6, 7) between a barrier position, in which they lie between the sea floor (A) and the surface (B), and a position in which such portions (6, 7) are immersed in the sea and allow the circulation of water above and below them.
