UP WELLING CURRENT-GENERATING SUBMARINE ARTIFICIAL LEVEE AND ITS CONSTRUCTION METHOD

PROBLEM TO BE SOLVED: To provide a up welling current-generating submarine artificial levee which enables a structure necessary for the generation of up welling current to be constructed as a lightweight structure of a minimum necessary size and which can be easily installed in a proper installation place on the bottom of the sea from on the ocean, and a construction method for the up welling current-generating submarine artificial levee. SOLUTION: This up welling current-generating submarine artificial levee comprises: a steel-pipe truss structure 100 which is composed of three main steel pipes 110 each arranged in such a manner as to correspond to three axial edges of a virtual trigonal prism, and a plurality of connecting materials 120 for connecting the main steel pipes to one another; and at least two shielding plates 130 which are elongated in the axial direction of the main steel pipe on the outer peripheral surface or inside of the steel-pipe truss structure, and which have surface angles different from each other. A hollow space inside the main steel pipe is sealed, and water can be injected into the sealed hollow space. COPYRIGHT: (C)2007,JPO&INPIT
