Improved underwater tsunami mitigation facilities

摘要

PROBLEM TO BE SOLVED: To provide an improved underwater tsunami disaster-proof facility, which can operate with high reliability due to a design to reduce a large amount of material cost and construction cost required for a fixed breakwater, avoid complicated device and action required for other movable breakwater and make use of natural force.SOLUTION: Wires 2 of a structure 1, which is assembled into a raft shape by connecting light natural materials such as round bamboos by the wire 2, are passed through ring-shaped anchor fittings 3, which are embedded in the sea bottom, and linked together and extended into a wall state under the sea by buoyant force of the light natural materials in an improved underwater tsunami disaster-proof facility.SELECTED DRAWING: Figure 1
