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 have blades and installed on bridge piers upstream bridge so that river water stream energy and moving ice energy are used for drums rotation. Curvature of drum blade provides initial blade edges contact with ice.
EFFECT: increased ice-cutting efficiency.
