METHOD OF CREATING ICE CROSSING Russian patent published in 2024 - IPC E01D15/14 

FIELD: ice engineering.

SUBSTANCE: method relates to creation of ice crossings for transportation of cargoes. Method consists in freezing on both sides and along the whole length of the ferry of steel cables. Steel washers rigidly connected to the cables are pre-installed on the cables. Washers are installed on cables with displacement of their attachment points vertically upwards relative to their center of gravity, which is determined depending on temperature gradient along ice thickness. Before freezing in, the ropes are stretched, and after their freezing in, the stretching forces are removed. To freeze ropes with washers into ice cover, they are heated to temperature above ice melting temperature by passing electric current through ropes. After their immersion into ice cover, supply of electric current is stopped. Ice crossing surface prepared in this way is exposed to low atmospheric temperatures (t<0 °C) until water is completely frozen in grooves formed during ice melting.

EFFECT: disclosed is a method of creating an ice crossing.
