Abstract
PURPOSE: To prevent the destruction of bank body, the overriding of wave, the reflection of wave and the washing-away of the leg part of the bank by a method wherein the energy of waves is absorbed by blocks having vacant spaces which dissipate the energy of the wave force and change the same into the thermal energy.
CONSTITUTION: A pair of block boards 1 with convex parts 2 formed on the outer- lateral side are arranged back to back at intervals, while a block beam 3 is bridged on the upper parts of the block boards 1. The block beam 3 has a pair of projections on the upper surface thereof. In addition, the block boards 1 have concave parts 5 on the lower surfaces thereof. The blocks thus formed are arranged to the right and left so that the convex parts 2 face each other, and, moreover, they are piled in several stages in such a manner that the concave parts 5 of the block boards 1 are fitted to the projections 4 of the block beam 3. As a result, plural vacant spaces are formed among blocks, thereby the energy of waves is absorbed.
