METHOD OF INCREASING CARRYING CAPACITY OF ICE COVER Russian patent published in 2018 - 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 via through openings formed in the ice cover along both edges of the crossing along its entire length. The bottom end of the pipe is made welded, and its upper end projects above 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 pipes wall thickness. The section length should exceed the maximum possible level of water fluctuations in the basin. At the upper end projecting from under the ice, a generator is installed, exciting longitudinal oscillations in the supports, and it is supplied with feedback sensor, which enables it to be configured on its own frequency transverse vibrations occurring as a result of a transformation brought by longitudinal waves in transverse field inhomogeneities in waveguides, i.e. on pipe portions with variable thickness. In the upper parts of the pipes, heat-insulating plugs are installed.

EFFECT: increased carrying capacity.
