METHOD TO DEVELOP ICE CROSSING Russian patent published in 2012 - IPC E01D15/14 

FIELD: construction.

SUBSTANCE: result is achieved by freezing-in steel ropes at both sides of a crossing along its entire length. At the same time elements are previously installed onto ropes as rigidly connected to them, prior to their freezing-in the ropes are stretched, and after their freezing-in the stretching forces are removed. To freeze-in ropes with elements into an ice cover, they are heated to the temperature above the ice melting temperature by sending electric current through ropes, electric current supply is interrupted after their submersion into the ice cover for the depth below half of the ice thickness, the ice crossing surface prepared in this manner is exposed to low atmospheric temperatures (t<0°C) until full freezing of water in grooves that occurred during ice melting, at the same time the freezing-in process is repeated many times.

EFFECT: preservation of higher weight-lifting capacity by development of compressing forces.
