<P>PROBLEM TO BE SOLVED: To increase attenuation effects on tsunami energy by developing an energy absorption type breakwater wall structure which is constructed as a breakwater or tide wall in a shallow sea area and raised from the foundation constructed on the bottom of sea, and comprises a thick beltlike wall made of reinforced concrete. <P>SOLUTION: There is provided a breakwater wall structure X such that a beltlike wall 1 has a reinforcement structure as a skeleton element by arranging bars and forming the beltlike water 1 in a concrete form for concrete installation, and also has a plurality of through hole parts 11 bored in parts of the concrete wall body (1) after the installation at regular or irregular intervals. At least ocean-side concrete wall surfaces 12 form inclined surfaces toward the through hole parts 11 with a negative gradient so that waves, tides, or tsunamis received by the wall part (1) are guided to the through hole parts 11 to diversify pressure reception directions and turbulent flows are generated at the through hole parts 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
