Abstract

PURPOSE: To prevent the structure from freezing and erosion by a method wherein on external plate made from a copper-nickel alloy is arranged on the external surface of the structure located on frozen water area.
CONSTITUTION: On the surface 13 of an inclined external plate adjoining the ice 12 of the external surfaces of the structure located on the frozen water area is arranged an external plate made from a copper-nickel alloy. Since the copper-nickel alloy is of high strength and of high erosion-resistance and moreover the ice does not attach to the surface of the alloy, erosion can be prevented. Simultaneously, since the ice does not attach to the structure even when the structure is jammed in a drift-ice, the effect of the drift ice force can be prevented.
