ICE TEMPORARY BRIDGE STRUCTURE Russian patent published in 2006 - IPC E01D15/14 

FIELD: floating bridges, for instance temporary bridges for load transportation over ice.

SUBSTANCE: structure includes ice blanket in which vertical holes are drilled for the full bridge structure length so that the holes are located from both bridge sides. Reinforced concrete blocks connected to ropes are inserted through the holes so that the blocks are located under the ice blanket. Discs having diameters exceeding hole diameters are connected to upper block ends. Rope lengths are selected to prevent ice blanket movement in upward direction with respect to initial ice position if flexural-gravity waves are generated in ice blanket.

EFFECT: increased load-bearing capacity.
