FIELD: construction. ^ SUBSTANCE: artificial substrate includes wave-cutting elements fixed on the bottom. At the same time substrate is arranged in the form of meshy bag, in which 1/3-1/4 part is filled with stones, and remaining part is charged with wave-cutting elements by 1/3-1/4, which have negative floatability. Bag is bound with yoke at the border between parts. For additional cancelling of waves, there are tapes of fine-mesh surface fixed on side surface of bag. Porous ceramic granules are used as wave-cutting elements, and haydite granules are also used. Meshy bad for strength may be arranged as double. ^ EFFECT: substrate makes it possible to increase wave-cutting effect and to reduce wave load at coastal zone, provides for environmental safety with simultaneous increase of stability and reliability. ^ 5 cl, 2 dwg |
