CONTROL SYSTEM FOR TIDAL WAVES

PURPOSE:To obtain a breakwater without damaging landscape by a method in which a float tube vertically movable by a given distance on the inside or outside of a steel tube is provided on the upper part of the steel tube in such a way as to float or sink the float tube according to the levels of tidal current. CONSTITUTION:A steel tube 1 is driven into the seabed ground 2, and holes through which sea water passes are drilled in the peripheral side of the tube 1. A float tube 4 vertically movable by a given distance on the inside or outside of the tube 1, and a space 4A is provided in the tube 4 to make it a float. A weight 5 is then set in the tube 4 and adjusted in such a way as to equalize the tip of the tube 4 with the sea water level WL, permitting it to exhibit a waves-breaking effect when tidal current comes and also it (tube 4) to float and sink according to the ebb and flow of tide. Plural steel tubes are arranged into a proper form to form a breakwater structure not damaging the natural landscape.
