FIELD: ice-breaking equipment for ice jam prevention in front of bridge during river freeze-up and in ice-drift periods.
SUBSTANCE: device is made as rotary drums cutting ice cover due to creating bending deformations in ice cover during drums rotation. Drums are installed on bridge piers upstream bridge and located under river water level. Drums have structures providing rotation thereof by water stream energy and creating low-pressure area under ice.
EFFECT: increased ice-cutting efficiency.
