Abstract
PURPOSE:To obtain a concrete covering block having excellent preventing effects on floating and suction of rubble-mound by using a block having through holes in a part of its body. CONSTITUTION:A spoiler 2 formed of projections 2a of a trapezoidal cross section is provided symmetrically to both ends of the inside 1a of a block 1. A downwardly projected skirt 3 is also formed along the peripheral edge of the downside 1b of the block 1, and a pair of tapered through holes 4 in an upwardly decreasing cross sectional area are formed between the top and bottom 1a and 1b of the block 1. The floating and toppling-over of the block due to a jet stream phenomenon from the rubble mound can thus be prevented.
