SHORE-PROTECTIVE STRUCTURE Russian patent published in 1997 - IPC

FIELD: hydraulic engineering. SUBSTANCE: shore-protective structure has blocks 1 with through-holes 2 of slot shape. Made in blocks 1 are three vertical parallel slits 3, 4, 5 with one of them located over block center, and two other slits are made on diagonally opposite sides of block at equal distances from edges of block. Each slit is of depth not less than half height of block 1 and of width not less than its thickness. Blocks 1 by means of slits 3, 4, 5 are cross-like interconnected into pairs. Installed in base of angles formed at their joining are wave suppressing screens of trapezoidal configuration. EFFECT: high efficiency. 7 dwg
