Abstract
Die Erfindung betrifft eine Fischaufstiegshilfe bestehend aus durch Stützpfeiler abgestützte verbundene Rinnenabschnitte, die zu einer spiralförmigen Rinne angeordnet sind und die aus Beton bestehen, wobei der Beton mindestens der Rinnenabschnitte ein Verbundmaterial enthaltend alkaliresistente Glasfasern und/oder Carbonfasern ist.The invention relates to a fish pass consisting of connected channel sections supported by support pillars, which are arranged to form a spiral channel and which are made of concrete, the concrete of at least the channel sections being a composite material containing alkali-resistant glass fibers and / or carbon fibers.
Description
Die Erfindung betrifft eine raumsparende Fischaufstiegshilfe an Wehren, Stauanlagen und fließenden Gewässern.The invention relates to a space-saving fish pass at weirs, dams and flowing waters.
Aus der
Diese Fischaufstiegshilfe ist raumsparend und aus Betonfertigteilen zusammensetzbar. Die Fertigteile sind, wenn die Anzahl sich im ökonomischen Bereich bewegen soll, allerdings sehr schwer und wirken in der Landschaft klobig.This fish pass saves space and can be assembled from precast concrete parts. If the number is to be within the economic range, the prefabricated parts are very heavy and look clumsy in the landscape.
Aufgabe der Erfindung ist es, die Fertigteile leichter zu machen, um den Transport- und Montageaufwand zu senken.The object of the invention is to make the finished parts lighter in order to reduce the transport and assembly costs.
Gelöst wird diese Aufgabe mit den Merkmalen des Anspruches 1. Eine vorteilhafte Ausgestaltung ist Gegenstand des Unteranspruches.This object is achieved with the features of claim 1. An advantageous embodiment is the subject of the dependent claim.
Durch die Verwendung von alkaliresistenten Glasfasern und/oder von Carbonfasern als Bewehrung für die spiralförmig zusammengesetzte Rinne und/oder die Stützpfeiler werden bessere Trageigenschaften insbesondere Zugbelastungen erzielt, werden die Rinnenmodule bei gleicher Größe wie Stahlbeton leichter, was den Transport- und Montageaufwand senkt. Die Fertigbauelemente sind ferner korrosionsfrei.By using alkali-resistant glass fibers and / or carbon fibers as reinforcement for the spiral-shaped channel and / or the supporting pillars, better load-bearing properties, especially tensile loads, are achieved, and the channel modules are lighter than reinforced concrete with the same size, which reduces transport and assembly costs. The prefabricated components are also corrosion-free.
Von besonderer Bedeutung ist, dass sich die Zahl der Windungen bei gleichem Raumbedarf erhöhen lässt, so dass sich das Gefälle reduziert. Die passierenden Fische werden so geringerer Strömung ausgesetzt, was die Stressbelastung senkt.It is of particular importance that the number of turns can be increased with the same space requirement, so that the gradient is reduced. The passing fish are exposed to lower currents, which reduces stress levels.
Alternativ oder gleichzeitig lassen sich die Breite und Tiefer der Rinne vergrößern. Auch das senkt die Stressbelastung.Alternatively or at the same time, the width and depth of the channel can be increased. This also reduces stress levels.
Dass die Fertigbauelemente filigraner hergestellt werden können, führt auch zu einer verbesserten Optik.The fact that the prefabricated components can be produced in a more filigree manner also leads to an improved appearance.
