   Die Erfindung benutzt die Eigenschaft des Eises, an   der Wasseroberfläche zu schwimmen,   zur Abspaltung des Eises von dem Treibwasser und erreicht diese Abspaltung wassersparend durch Ein-

Aus dem Oberwasser scheidet sich infolge des geringen spezifischen Gewichtes das Eis ab und bleibt schwimmend vor dem Däker, der das reine Treibwasser nach unten weiter führt. 



   Um eine Anhäufung durch das durch das Oberwasser herangeführte Eis zu verhindern, ist das Oberwasserkanalende nach der Dükermündung abfallend, als schwach geneigte schiefe Ebene ausgebildet (Fläche   .

Das vom Eis gesonderte Treibwasser steigt durch den   Düker   in die Fortsetzung der Oberwasserführung.

 penetration of ice into the machines, the need to separate the ice from the drift water. At present, ice is excreted from ice locks with pills or ice is removed from Hard.



   The invention uses the property of the ice to swim on the surface of the water to split the ice from the driving water and achieve this separation in a water-saving manner by
 EMI1.2
 of Fig. 4), which directs the headwater to any hydroelectric machine.



   This channel is downstream of the cross section. AB by installing two floors, one horizontal and one inclined, subdivided (Fig. 4) in such a way that the headwater descends like a culvert below these two and above the lowest actual channel floor and then rises again to approximately the previous height. The difference in height of the water surface before and after the Dillzer is a result of the sum of the resistance to friction and resistance to change of direction and is practically very successful.

 which is dependent on the ratio of the water depth to the width of the small cross section of FIG. 1.

   The fold line of the inclined plane H2L1M1N1 and its delimitation against the underwater of the culvert, which is formed by a parallel transverse wall (C1D1M1N1 in FIG. 5) to the surface ElFilBl, shows

Due to its low specific weight, the ice separates from the upper water and remains floating in front of the roof, which carries the pure drift water further down.



   To prevent the ice from accumulating through the headwater, the end of the headwater channel sloping down after the culvert mouth is designed as a gently sloping inclined plane (surface in order to fall into the ice slide, which is arranged, for example, transversely to the water flow (surface H2LlMlNl of FIG. 5) and to be removed to the side. The drift water, separated from the ice, rises through the culvert into the continuation of the headwater.



   The height of the edges of the ice ramps k1 and k2 relative to the water level are determined by the thickness of the ice sheet and by the speed of the headwater and is particularly the
