专利说明:
Description: The invention relates to a device arranged on a body of water separated by a barrier into an underwater and an upper water for the migration of aquatic animals between the underwater and the upper water according to the preamble of claim 1. In particular, the invention relates to further developments of the known Denil fish pass. The Denil fish pass is a technical fish migration aid with a long tradition. The original form of the Denil fish pass was built at the beginning of the 20th century and achieved good results with regard to salmon migration. The functional principle of the Denil fish pass is based on the fact that lamellae, which are usually placed in a steeply inclined body, create turbulence, which subsequently has a backwater effect on the running water, which slows down the flow speeds in the walking corridor, especially in the middle of the stream. This effect makes it possible for fish to migrate with a significantly higher gradient and significantly less space. This aspect provides a blatant advantage in terms of area and cost compared to other common fish pass systems, such as slot pass, pool pass and bypass channel. Document US 1 621 170 discloses a pool pass, also called "fish ladder", which is used to drain fish, for example via a transverse structure in a river. In this device, however, large-scale structural measures are necessary, for example, the basin cascades have to be digged and / or concreted into the ground next to the river, which entail both ecological and economic disadvantages. So while in a slot pass, a pool pass or a bypass channel, the overall height is bridged in sections by the stringing together of individual pools, the height reduction takes place continuously in the Denil fish pass. The known designs of the Denil fish pass usually show poor passability for small fish species and juvenile stages. On the one hand, this is due to the relatively high flow velocity, which these aquatic animals lack the strength to overcome. On the other hand, small fish species, juvenile stages and several species of other aquatic animals, including numerous large cyprinids, have a strong sole cover, which leads to a potential reduction in the efficiency of conventional Denil fish passports. [0006] Document EP 3 214 225 A1 discloses a further development of the Denil fish pass, in which the lamellae are introduced into the system as a U-shape. This arrangement significantly reduces the flow speed on the ground by means of the cross connections of the slats near the bottom. However, this arrangement creates turbulence, which results in a strong, upward flow impulse. When sampling such denil fish passes, it became clear that small fish species and bottom-oriented hikers are underrepresented. According to the inventors, this is primarily due to the high, upward flow velocities. In the previously known versions of Denil fish passes, the flow velocities in the z direction, i.e. upwards in the direction of a normal to the longitudinal axis of the channel body, exceed those in the x direction, that is, along the longitudinal axis of the channel body. As a result, the small fish lose their orientation during the passage of the system or drift away in the turbulence, which inhibits the migration. It is the object of the present invention to improve a device for the migration of aquatic animals between the underwater and the upper water of a body of water in such a way that it can also be overcome for small fish species, juvenile stages and generally for aquatic animals with a strong sole cover. The invention solves this problem by an inventive development of the aforementioned devices according to the characterizing features of claim 1. Advantageous embodiments of the invention are defined in the subclaims. The device according to the invention, arranged on a body of water separated by a barrier into an underwater and an upper water for the migration of aquatic animals between the underwater and the upper water, has at least one channel body with an upstream end that communicates with the upper water and an underwater end , which communicates with the underwater, causing water to flow from the headwater through the channel body to the underwater, the channel body having a longitudinal axis running between the upstream end and the underwater end, the bottom of the channel body at least in sections along the longitudinal axis of the channel body with a Cover layer made of natural sole substrate and / or broken material is provided and plate-shaped lamellae are arranged in the channel body transversely to the longitudinal axis of the channel body, and is characterized in that the cover layer essentially runs along it g of the longitudinal axis extending web, wherein a second height of the cover layer in the region of the web along the longitudinal axis is substantially constant, and that the slats are formed in two parts from a right part lamella and a left part lamella, the right part lamella and the left part lamella each lie on the side of the web. The inventive device for the migration of aquatic animals advantageously enables a walking corridor of constant height to be provided along the web between the right and left partial slats. The flow velocities in the z direction are reduced compared to the flow velocities in the z direction that occur in the previously known versions of Denil fish passes. This creates a continuous CH 714 606 A2 concentrated current line, which also makes it possible for small-size fish and sole-oriented aquatic animals to migrate. The bottom of the channel body is expediently provided with the cover layer over its entire length, the web running over the entire length of the channel body, a first height of the cover layer below the web and the second height of the cover layer over the entire length of the channel body are essentially constant. In preferred embodiments of the invention, the cover layer in the region of the web is provided exclusively with broken material, as a result of which the web forms the shape of a “stone tongue” made of broken material. At its bottom, the web, or the stone tongue, adjoins the wide-area remaining body of the cover layer made of sole and / or broken material. The small animals can migrate along the holes between the angular broken material and are protected from predators. In this document, “in the area of the web” refers to the spatial volume that the web occupies, that is to say essentially the cross-sectional area of the web multiplied by the length of the web. In order to secure the cover layer, in particular the breakage material of the web, against discharge and rearrangement, it is preferably arranged in gabions or grids, the gabions or the grids defining the outer spatial shape of the cover layer. Gabions are basket-like or cage-like structures, preferably made of metal or plastic. In preferred embodiments of the invention, the right partial lamella and / or the left partial lamella is inclined, preferably at an angle of 45 degrees, towards the upper water-side end of the channel body. To achieve a higher rigidity of the lamellae, it is expedient if the lamellae have transverse elements in their upper region which connect the right part lamella and the left part lamella to one another. In preferred embodiments of the invention, the right partial lamella and / or the left partial lamella have a wing, preferably made of metal, the wing being attached to the left or right partial lamella along a first side edge and laterally along a second side edge abuts the web. A metal wing increases the lifespan of the slat. In preferred embodiments of the invention, the lamellae can be inserted into, preferably made of metal, guide rails and can be pulled out of them. The maintenance and, if necessary, the replacement of the slats is considerably simplified in this way. In preferred embodiments of the invention, the lamellae are designed to be releasably attachable in the guide rails by means of bolts and spring plugs. An advantageous and non-limiting embodiment of the invention is explained in more detail below with reference to the drawings. 1 shows an oblique view from above of a first exemplary embodiment of a device according to the invention for the migration of aquatic animals. FIG. 2 shows the device according to the invention from FIG. 1 in a longitudinal section along a longitudinal axis. FIG. 3 shows the device according to the invention from FIG. 2 in a section B-B. FIG. 4 shows a top view of the device according to the invention from FIG. 1. 1 to 4 each show a schematic representation of an inventive device 1 for migrating aquatic animals according to a first embodiment. By means of the device 1, aquatic animals can overcome a barrier in a body of water and migrate from an underwater 4 into an upper water 5, or vice versa. If the body of water is a flowing body of water, for example a river, the device 1 is arranged essentially along a flow direction FR. The device 1 comprises a channel body 6 with an upstream end 3, which communicates with the upper water 3, and with an underwater end 2, which communicates with the underwater 4. The channel body 6 extends along a longitudinal axis 8. Consequently, the water flows from the upper water 5 essentially along the flow direction FR or along the longitudinal axis 8 into the underwater 4. The device 1 can have 3 end walls 24 in the region of the upper water-side end. In the channel body 6 8 plate-shaped slats 7 are arranged at substantially constant intervals transversely to the longitudinal axis. These fins 7 cause a backflow effect of the running water, which slows down the flow rate accordingly. The slats 7 are formed in two parts from a right part slat 7A and a left part slat 7B. The lamellae 7, that is to say the right-hand partial lamella 7A and the left-hand partial lamella 7B, are introduced obliquely in the direction of the end 3 of the channel body 6 on the upper water side. The angle WL, which defines the inclination of the slats 7, is preferably 45 degrees. The sole of the channel body 6 is in sections along the longitudinal axis 8, but preferably over the entire length of the channel body 6, with a cover layer 9 made of natural sole substrate, broken material, and / or one CH 714 606 A2 defined mixture of base substrate and broken material. Kantkorn can also be added. Kantkorn is a wear-resistant, broken gravel and can further reduce the water's near-river flow rate. By introducing broken material and / or kernel grain into the device 1, in particular into the channel body 6, the aquatic animals are provided with a continuous gravel gap space, which increases the likelihood of a successful migration and opens up the migration of macrozoobenthos (gapless insect larvae) and sole-bound fish can be. For aquatic life with a strong sole cover, the barrier can only be overcome in this way. A body 14 of the cover layer 9 with a first height 11 can be introduced over the entire width of the bottom of the channel body 6, the width extending orthogonally transverse to the longitudinal axis 8 of the channel body 6. The cover layer 9 has, preferably centrally in relation to its width, a web 10 with a second height 12 which runs essentially along the longitudinal axis 8. At its bottom, the web 10 connects to the rest of the body 14 of the cover layer 9, which body 14 is located below and laterally below the web 10 when the cover layer 9 is introduced over the entire width of the bottom of the channel body 6. The right partial lamella 7A and the left partial lamella 7B then each lie laterally on the web 10 and lie on the body 14 of the cover layer 9, as shown in FIG. 3. The right part lamella 7A and the left part lamella 7B can alternatively be embedded up to an embedment depth in the body 14 of the cover layer 9. The depth of embedding can vary and can be a maximum of the first height 11 of the cover layer 9, that is to say extend to the bottom of the channel body 6. Alternatively, the body 14 of the covering layer 9 can only extend partially along the width of the sole, for example only below the web 10, the right partial lamella 7A and the left partial lamella 7B then each reaching as far as the bottom of the channel body 6. The first height 11 and the second height 12 of the cover layer 9 are preferably essentially constant over the entire length of the channel body 6. The cover layer 9 in the region of the web is preferably provided exclusively with broken material. “In the area of the web” in this document refers to the spatial volume that the web 10 occupies, that is to say essentially the cross-sectional area of the web 10 multiplied by the length of the web 10, in the present example of the first embodiment, this length corresponds approximately to that Length of the bottom of the channel body 6. The cross-sectional area of the web 10 is calculated, for example in the case of a rectangular or square cross-sectional area of the web 10, from the second height 12 of the cover layer 9 multiplied by the distance along which the web 10 at its bottom to the remaining body 14 of the cover layer 9 is adjacent. In the present first embodiment of the invention, however, the web 10 has a trapezoidal cross section and is to be calculated accordingly. The web 10, as shown in FIG. 3, for example, in this case has the shape of a “stone tongue”. The sole substrate, the broken material and / or the square grain can / can be secured against discharge and rearrangement by means of gabions 13, which are basket-like or cage-like structures, usually made of metal, or grids. The gabions 13 or the grids then define the outer spatial shape of the cover layer 9. The slats 7 can be fastened to the gabions 13. If the slats 7 lie directly on the bottom of the channel body 6, they can be fastened there. The slats 7 can in any case be attached to side walls 20 of the channel body 6. The right partial lamella 7A and / or the left partial lamella 7B can have a wing 15, which is preferably made of metal, the wing 15 being attached along a first side edge to the right partial lamella 7A or to the left partial lamella 7B and along one second side edge bears laterally on the web 10. In the present first embodiment of the invention, the second side edges of the wings 15 each have a shape that is complementary to the side edges of the web 10. As a result, the wings 15 lie flush against the web 10 along their second side edges. The lamellae 7 can have transverse elements 16 in their upper region which connect the right part lamella 7A and the left part lamella 7B to one another. As a result, the rigidity and handling can be improved. Furthermore, the device 1 upstream of the end 3 on the upper water side can have a rubber apron 17 in the region of the sole in order to counteract an underwashing. The rubber apron 17 can be covered with a sole substrate and / or broken material. The lamellae 7, that is the right part lamella 7A and the left part lamella 7B, can be inserted into and can be pulled out of guide rails 21, preferably made of metal, the right part lamella 7A and the left part lamella 7B each by means of bolts 22 and spring pins 23 (in FIG. 3, for reasons of clarity, only either bolts 22 or spring pins 23 are shown for each right partial lamella 7A or left partial lamella 7B) are designed to be releasably attachable in the guide rails 21. The device 1 can furthermore have a light shaft 18, the light shaft 18 being arranged on the side of the channel body 6 and a viewing window 19 being able to be introduced into a side wall 20 of the channel body 6 within the light shaft 18. By means of a corresponding structure of the cover layer 9, in particular in the area of the web 10, a guiding flow through the web 10 can be generated. This can increase the probability of a successful hike for sohl4 CH 714 606 A2 near hikers. Furthermore, the gap system of the sole substrate or the breakage material can be opened up for the migration of macrozoobenthos (insect larvae that live in the gap) as well as for sole-oriented fish species. The body of water, the topographical conditions or the barrier can require that the end 3 on the upper water side is connected to a relaxation pool or a cascade of upstream water with rising pool water levels, and / or that the end 2 on the underwater side is connected to a relaxation pool or an underwater Pool cascade with falling pool water levels is connected. Furthermore, the channel body 6 can be formed from two parts with an intermediate resting pool. It can be mentioned that in a device 1 according to the invention the channel body 6 can also be designed differently. For example, the channel body 6 can have a circular or elliptical cross section in order to take into account special types of aquatic animals, constructive ideas or topographical conditions of the water or the water landscape. Likewise, the geometric shape of the web 10, the lamellae 7, 7A and 7B, and the wing 15 can each be complex and / or polygonal, and likewise the arrangement of the lamellae 7, 7A and 7B, on or in the cover layer 9 can vary accordingly become. The structural structure of the cover layer 9 can be composed of all types of natural and artificial materials, such as, for example, sole substrate, broken material, square grain, gravel, rock, wood, ceramic, metal, textile, concrete, sand, plastic or the like, and have all possible mixing ratios of such materials mentioned above. Various materials and material mixtures can be introduced in layers, that is to say in a predetermined layer sequence, and / or mixed within the cover layer 9. The cover layer 9 can be secured against discharge and rearrangement by means of gabions 13, grids, or other types of basket or cage-like structures made of metal, wood, fiber mesh, textile, plastic or the like. Alternatively, the material of the cover layer 9 can be introduced into a depression in the bottom of the channel body 6, for example a concrete basin-like depression, and can be secured against discharge and rearrangement by means of a grid or net. It should also be mentioned that the device 1 according to the invention can also be used on non-flowing waters both for migrating and for migrating aquatic animals.
