<p>PROBLEM TO BE SOLVED: To provide a block for an artificial submarine ridge, as a solution for conventional technical problems, that is, to provide a block that is easy to be grounded at a preliminarily planned position and, to be more concrete, to provide a block whose undersea falling posture is easily stabilized.SOLUTION: The block for an artificial submarine ridge of the present invention constitutes an artificial submarine ridge that is constructed in the bottom of the sea. The block includes: a body part; a hollow part for penetrating the inside of the body part; and a buoyancy body for generating a buoyant force. By having the buoyancy body, there is installed isolation between the center of gravity position and the center of buoyancy position of the block for an artificial submarine ridge in the undersea falling posture. Consequently, a restoring force against rotation can be demonstrated.</p> |
