<；P>；PROBLEM TO BE SOLVED: To provide a block throw-in method for the construction of an upwelling current generating structure with excellent working efficiency, reliability and versatility by restraining individual blocks from flowing by the resistance of seawater and the influence of an ocean current or the like when throwing the blocks for the construction of the upwelling current generating structure into the sea, thereby reducing the dispersed range of blocks so that the blocks accurately land in target positions to accurately construct the upwelling current generating structure of a desired shape. <；P>；SOLUTION: The block throw-in method comprises a block connecting process for connecting a plurality of blocks separated from one another by connecting members, and a block throw-in process for throwing the plurality of blocks connected by the connecting members simultaneously into the sea. <；P>；COPYRIGHT: (C)2007,JPO&INPIT
