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 with spikes. Drums are installed on bridge piers upstream bridge and located above water level. Drums are installed at a level enough for ice cutting by drum spikes. Arranged under drums are platforms having upper inclined surfaces pressing ice to drum spikes for ice shearing. Device also has ice separation wedges for moving ice pieces apart downstream drums.
EFFECT: increased ice-cutting efficiency.
