METHOD FOR INCREASING CARRYING CAPACITY OF ICE COVER Russian patent published in 2017 - IPC E01D15/14 

FIELD: construction.

SUBSTANCE: carrying capacity of the ice cover is increased by means of steel pipes lowered vertically to the basin bottom through the through openings formed in the ice cover along both sides of the crossing along its entire length, the bottom end of the pipe being made welded and its upper end projecting over the ice surface. The pipes are made in the form of telescopic supports. The section of the movable element of the telescopic support at the point of its connection with the immovable one is made with inhomogeneities in the form, for example, of the variability of the wall thickness of the pipes. The section length must exceed the maximum possible level of water fluctuations in the basin. At the upper end of the pipe projecting from under the ice, a generator is installed, exciting longitudinal oscillations in the supports, which will be transformed into transverse ones in the places of inhomogeneities in the waveguides, i.e. on pipe portions with variable thickness. In the upper parts of the pipes, heat-insulating plugs are installed.

EFFECT: increasing the carrying capacity.
