FIELD: construction.
SUBSTANCE: carrying capacity of the ice cover of the ferry is increased by means of steel pipes that are lowered vertically to the bottom of the pool through holes formed in the ice cover along both edges of the ferry along its entire length. The bottom end of the pipe is made brewed, and its upper end protrudes above the ice surface. The upper parts of the pipes are equipped with a free-wheeling piece around the vertical axis of symmetry in the form of a coaxial cylinder, the length of which must be not less than the maximum difference in the water level in the pond, and a helical screw-shaped arrangement is installed on its surface.
EFFECT: increasing the carrying capacity.
