Abstract

PURPOSE:To simplify the combination of blcoks as well as make the installation of them better by forming four legs of a block to be used in footing work or water-breaking work into a trapezoidal form. CONSTITUTION:A block 1 has a trapezoidal form of legs 3A, 3B, 3C, and 3D projecting from each face of its square pillar body 2. The thickness A of each of the leg 3 is made shorter than the width A' of one side of the square pillar body 2. In the placement of the block 1, the blocks 1 are stacked up while coupling the leg 3 and dented part of the square pillar bodies side by side with one another and alternately, whereupon the blocks are coupled with one another while keeping them in blocked form. Thus, the whole of the blocks settles as such even at the time of frontal scouring work to exhibit water-breaking and footing effects. Also, the force of wave can be reduced and diffused by the tips of the leg 3.
