WAVE CONTROLLING STRUCTURAL BODY

PURPOSE:To reduce the weight of a structural body and reduce the installation cost by opening a number of through holes on the bottom surface of the structural body and allowing said through holes to communicate to the space inside or outside the structural body. CONSTITUTION:A structure body 10 having a wave control wall 12 in semicircular form on a bottom plate 11 is installed on a thrown stone mound 14 built on the sea bottom 13, and a space 15 having a semicircular section is formed inside. A number of through holes 16, 16,... which lead to the inside space 15 are penetration-opened on the bottom plate 11 of the structural body 10. A pumping-up pressure due to the upward water pressure which acts onto the bottom surface, accompanied with the advance of waves, is dispersed and absorbed into the opened ports of the through holes 16 and reduced. Therefore, the weight for resisting the pumping-up pressure can be reduced.
