Icebreaker (hydraulic engineering)
As icebreakers also Eisbock or Eisabweiser , upper current side built shelters and wedge-shaped reinforced bridge piers are to treibeisgefährdeten bridges designated.
The beams or iron rails rammed into the river bed a few meters above the bridge are intended to protect the bridge yokes and pillars against the ice drift, specifically the rush of large, compact floating ice floes by dividing these ice floes into relatively harmless small floes by the icebreaker before they reach the bridge .
In Saxon Switzerland, bulwarks called “Habe” were built to protect against ice and flooding on the Elbe.
