Abstract

The fish passage has inclined channel structure (4) that falls directly from above the weir (1) of river. The channel structure is provided with top-side water inlet (2) and lower-side water outlet (3). Large independent support structures (6) are freely suspended on specific side of channel structure for supporting the channel structure. Several water obstacles (5) are arranged in between the water inlet and water outlet for reducing kinetic energy of water so as to provide passability for fish and other aquatic organisms.

Description

[0001] Die Erfindung betrifft eine Vorrichtung, welche die Fischpassierbarkeit an Stufen in Fliessgewässern verschiedener Grösse gewährleistet. The invention relates to a device which ensures fish passability at stages in rivers of different sizes.

[0002] Der Abfluss in Fliessgewässern wie Flüssen und Bächen wird oft durch Stufen, Wehre und andere Hindernisse kontrolliert. Diese Stufen behindern oft aber die Wanderung von Fischen und anderen Wasserorganismen. Um dieses Problem zu lösen sind verschiedene Arten von Fischpässen bekannt. Ihre Bauweise macht sie aber besonders teuer, da sie entweder in der Form eines Umgehungsgewässers eine grosse Bodenfläche beanspruchen oder wie bei aufgelösten Blockrampen massive bauliche Änderungen an der Stufe selbst nötig machen. In gewissen Fällen wie z.B. in einem Dorfkern sind Umgehungsgewässer aufgrund von Sachzwängen nicht möglich. In anderen Fällen wie zum Beispiel temporären Hindernissen sind teure bauliche Massnahmen wegen der hohen Kosten nicht angemessen. The drainage in rivers such as rivers and streams is often controlled by steps, weirs and other obstacles. However, these steps often hinder the migration of fish and other aquatic organisms. To solve this problem, various types of fish passes are known. However, their construction makes them particularly expensive because they claim either in the form of a bypass water a large floor area or make as in dissolved block ramps massive structural changes to the stage itself. In certain cases, such as e.g. In a village center, bypass waters are not possible due to constraints. In other cases, such as temporary obstacles, expensive construction measures are not appropriate because of the high costs.

[0003] Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zu entwickeln, die an oben erwähnten Hindernissen angebracht werden kann und das natürliche Kontinuum des Fliessgewässers wiederherstellt, sodass Fische und andere Organismen entlang der Fliessrichtung wieder wandern können. Object of the present invention is to develop a device that can be attached to the above-mentioned obstacles and restores the natural continuum of the watercourse, so that fish and other organisms along the direction of flow can walk again.

[0004] Die Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Patentansprüchen. Der Vorteil der Erfindung besteht darin, dass die Vorrichtung deutlich kostengünstiger und ohne Trockenlegung des betroffenen Hindernisses angebracht werden kann. Die Vorrichtung kann nachträglich angebracht und leicht auch wieder entfernt werden, was sie auch für temporäre Lösungen geeignet macht. Die Vorrichtung ist ausserdem äusserst platzsparend und lässt sich darum auch da anbringen, wo der Boden um das Hindernis herum nicht für bauliche Massnahmen verfügbar ist. The object is solved by the features of patent claim 1. Advantageous developments emerge from the dependent claims. The advantage of the invention is that the device can be mounted much cheaper and without draining the affected obstacle. The device can be retrofitted and easily removed, which makes it suitable for temporary solutions. The device is also extremely space-saving and can therefore also be attached where the ground around the obstacle is not available for structural measures.

Es zeigt <tb>Fig. 1 :<SEP>Freihängender Fischpass seitlich an einer Wehrstruktur angebracht <tb>Fig. 2 :<SEP>Freihängender Fischpass seitlich an einer Stützstruktur angebrachtThe invention will be explained in more detail with reference to an embodiment which is illustrated in the drawings. It shows <Tb> FIG. 1: <SEP> Free-hanging fish pass attached to the side of a weir structure <Tb> FIG. 2: <SEP> Free hanging fish pass attached to the side of a support structure

[0006] Fig. 1 zeigt die Vorrichtung in einer Ausführung, bei der die Kanalelemente 4 eine vorhandene Mauer 7 einer Staustufe die parallel zur Fliessrichtung des Wassers verläuft, als strukturelle Basis verwendet. Die Kanalelemente 4 sind dabei nur in wenigen Lagerpunkten 6 mit der Mauer verbunden und stellen sonst eine von der Mauer 7 unabhängige Struktur dar. Die Vorrichtung fällt direkt über die Staustufe 1 ab. An der oberen Kante der Staustufe befindet sich der Wasserzulauf 2. Nachdem die kinetische Energie des Wassers im Kanal durch Elemente 5 wie geschlitzte Platten oder Bürsten reduziert wurde, fliesst es durch den Wasser-Ablauf 3 ins Unterwasser. Fig. 1 shows the device in an embodiment in which the channel elements 4 an existing wall 7 of a barrage which runs parallel to the direction of water flow, used as a structural basis. The channel elements 4 are connected only in a few storage points 6 with the wall and otherwise represent an independent of the wall 7 structure. The device drops directly over the barrage 1 from. At the upper edge of the barrage is the water inlet 2. After the kinetic energy of the water in the channel has been reduced by elements 5 such as slotted plates or brushes, it flows through the water drain 3 into the underwater.

[0007] Auf Fig. 2 ist eine ähnliche Ausführung der Vorrichtung zu sehen, bei der aber die vorhandenen Strukturen 7 der Staustufe nicht als strukturelle Abstützung geeignet oder nicht vorhanden sind. Die Kanalelemente 4 sind da an Stützstrukturen 8 angebracht, die im Untergrund 9 festgehalten werden. Wiederum bilden die Kanalelemente eine vom Boden grösstenteils unabhängige Struktur. 2, a similar embodiment of the device can be seen, but in which the existing structures 7 of the barrage are not suitable as a structural support or not available. The channel elements 4 are attached to support structures 8, which are held in the ground 9. Again, the channel elements form a largely independent structure from the ground.
