FIELD: production processes. ^ SUBSTANCE: proposed method can be used in constructing ice ferry by placing artificial structures thereon. The invention covers separate parts of artificial structure (board deck) that can be safely dismantled and repeatedly used. The method consists in laying the board deck onto the ice surface. First, the ice surface is covered with a polyethylene film, and then board decks are placed onto the said film, one across the other. The boards of every deck are laid end-to-end all across the fatty width and separated by polyethylene film. The surface of laid layers is also separated by the said film. ^ EFFECT: ice ferry strengthening. ^ 1 dwg |
