Definitions

  • the present invention relates to a system for protecting beaches against marine erosion.
  • reefs are generally aligned parallel to the coast, so as to form an inward basin, and are mutually spaced by openings which connect the inward basin to the open sea and allow the passage of boats.
  • Barriers are known from the background art, which however have the function of controlling the flow of water in a canal or the inflow and outflow of water from basins in order to control their level, but without affecting the recirculation of the water and without affecting the formation of sand deposits on the beds of bodies of water. Barriers of this type are known, for example, from US patents no. 194,922, 3,756,032, and 4,103,497, and from German patent no. 859 129.
  • the aim of the present invention is to provide a system for protecting coasts which allows to obviate the shortcomings of known systems.
  • each barrier is composed of two fixed structures which are installed on the sea floor, a wall being arranged between said structures and being supported therein and comprising two portions which can move with respect to a horizontal axis which is immersed at an intermediate depth of the sea, and means for actuating said portions between a barrier position, in which they lie between the sea floor and the surface, and a position in which said portions are immersed in the sea and allow the circulation of water above and below them.
  • the reference numeral 1 generally designates a barrier according to the invention.
  • the barrier 1 is composed of two structures 2 and 3, which are installed and anchored at a preset distance on the sea floor A.
  • the height of the structures is lower than the depth H of the sea in the point where they are installed, so that they are immersed below the level B of the surface of the sea.
  • Each one of the two structures 2 and 3 is provided with vertical guides 4 and 5, in which the opposite ends of two portions 6 and 7 which form a barrier wall, generally designated by the reference numeral 8, can slide.
  • a horizontal shaft 9 which has an axis C which is supported, by means of its opposite ends, so that it can rotate within the structures 2 and 3.
  • the shaft 9 is actuated by motor elements, which are installed in chambers provided in the structures 2 and 3, and is provided with pinions 13, which mesh with vertical racks 10 and 11, which are rigidly coupled to the opposite faces of the portions 6 and 7. Therefore, by actuating the shaft 9 in one direction or the other it is possible to lower the portion 6 and at the same time lift the portion 7, and vice versa.
  • the shaft 9 is arranged at an intermediate level, which is half of the depth H, and the height of the portions 6 and 7 is chosen so that by lifting the portion 6 and lowering the portion 7 the upper edge of the portion 6 is arranged at the level of the surface B of the sea or slightly above it, while the lower edge of the portion 7 rests on the sea floor A.
  • the portions 6 and 7 integrate each other, forming a barrier which, during heavy seas, prevents the water of the sea from overflowing into the inward basin and causing the erosion of the coast.
  • the portion 6 When the sea is calm, instead, the portion 6 is lowered, while the portion 7 is raised, so as to reduce the overall height of the wall 8 and allow the recirculation of water above and below it.
  • Figures 4 and 5 illustrate a different embodiment in which the barrier wall 8 is constituted by two portions 6 and 7, which are rigidly coupled along a plane which is substantially diametrical with respect to the shaft 9, so that they can pass from a barrier position to the recirculation position by means of the rotation of the shaft 9.
  • the portion 7 comprises a chamber 12, which is connected to the atmosphere by means of a duct and is suitable to be flooded, by means of suitable valve systems, with seawater and emptied with the aid of a pump.
  • the wall 8 is kept in the barrier position by differentiating the weight of the portions 6 and 7 in order to create a moment which keeps the portion 7 rested on the sea floor.
  • the chamber 12 is sized so that expelling the water contained therein produces buoyancy adapted to create a moment sufficient to rotate the wall 8 from the barrier position to the horizontal recirculation position.
  • valve systems which are suitable to close hermetically the chamber 12 after filling and allow its emptying by pumping compressed air therein.
  • buoyancy shown for the embodiments of Figures 4 and 5
  • the same concept of buoyancy can be applied to the embodiment of Figures 1-3, by forming in the portions 6 and 7 chambers which are alternately flooded with water or emptied by introducing air therein, so that when the wall 8 must assume the barrier position, the portion 7 is flooded and the portion 6 is emptied, and vice versa when the wall must assume the recirculation position.
