Abstract

Es wird ein Schlauchwehr mit einem an einer Wehrsohle (1) befestigten, mit Wasser befüllbaren Schlauch (2) als Staukörper und mit einer am Schlauch (2) aufliegenden flexiblen Membranbahn (7) beschrieben, die mit ihrem oberwasserseitigen Ende zugfest gegenüber dem Schlauch (2) gehalten und mit ihrem unterwasserseitigen Ende (10) mit Abstand vom Schlauch (2) an der Wehrsohle (1) verankert ist. Um vorteilhafte Strömungsbedingungen zu erhalten, wird vorgeschlagen, dass die Membranbahn (7) zwischen einer oberwasserseitigen Anlage am Schlauch (2) und der unterwasserseitigen Verankerung (8) frei geführt ist und eine flexible Leitrampe für den Überfallstrahl bildet und dass das unterwasserseitige Ende (10) der Membranbahn (7) mit einer Spanneinrichtung (11) verbunden ist.

Figure imgaf001
A hose weir is described with a hose (2) that is attached to a weir base (1) and can be filled with water as a bluff body and with a flexible membrane web (7) that rests on the hose (2) and has a tensile strength with its upstream end relative to the hose (2 ) and is anchored with its underwater end (10) at a distance from the hose (2) on the weir base (1). In order to obtain favorable flow conditions, it is proposed that the membrane web (7) be guided freely between a surface-side bearing on the hose (2) and the underwater-side anchorage (8) and form a flexible guide ramp for the overflow jet and that the underwater-side end (10) the membrane web (7) is connected to a tensioning device (11).
