ICE ROAD CROSSING Russian patent published in 2019 - IPC E01D15/14 

FIELD: transportation.

SUBSTANCE: invention can be used in creation of seasonal automobile crossings on natural ice during ice-freezing on rivers and lakes. To achieve technical result at the beginning of freeze-up, when thickness of ice cover h reaches value ≥0.1 m, using means of small-scale mechanization from coast to shore across the future passage at a short distance from each other narrow narrowed lanes and lowered in them transverse bearing elements made in the form of a float, which in cross section of the half-pipe by cutting the pipe horizontally, note here that rounded part is directed downwards while cut point is closed by horizontally located support plate that is reinforced by lengthwise diaphragm and tightly secured on pipe with its ends tightly plugged with semi-circular shape. Along the entire length of the crossing, one or more ropes are laid on top of the transverse bearing elements for each track, in the form of blind non-through cuts in ice with depth of 0.05 m, which are poured with water. After freezing of ropes and natural increase of ice from below to design value it is possible to pass by ferrying of cars with weight of up to 20 t depending on number of ropes under each track. In spring, when operation of crossing becomes dangerous, by means of same cables floats are pulled out to shore, disconnected from ropes and stored until next fall.

EFFECT: invention is aimed at increasing of ice capacity lifting capacity.
