Definitions
- the invention relates to a hose weir with a substantially horizontal within a Flow cross-section of a body of water running from a rubber-elastic Membrane and a support structure forming a bottom of the water, on the the tube body is sealingly attached along its longitudinal extent, the Hose body extending from one side wall of the support structure along the sole an opposite side wall, and an inner sealed cavity has, which can be filled with a fluid, depending on the degree of filling To regulate backwater levels, with both side walls essentially in vertical Direction.
- hose weirs are generally known and are distinguished from weir constructions, for example made of steel plates, due to their simple construction and avoiding rotating parts.
- the cavity of the hose body can either be filled with air or water. Due to a certain flexibility of the Hose weirs are insensitive to bed load and sedimentation.
- Hose weirs are usually used up to a dam height of approx. 6 meters.
- Under essentially vertical side walls shall in the present If an angle to the vertical of 20 ° is understood.
- Such vertical Side walls are particularly made of space or weirs several fields arranged side by side are common. Especially when converting from existing weir systems, for example in steel construction, to the hose weir technology a change in the vertical sidewall course usually comes from economic Reasons not considered.
- the known hose weirs are used, for example, as weirs with fixed or in particular variable stowage target, because with the help of regulating systems also flexible stowage systems can be operated automatically and maintenance-free.
- Other use cases are, for example, so-called culture weirs, temporary barriers (e.g. oil weirs), the Flood protection, fresh / salt water barriers and the control of waste water flows.
- the attachment of the hose body to the support structure is done with the help of mounting rails.
- bolt-shaped steel anchors which are attached to a so-called bottom rail, are cast in. Threaded portions of the anchors protruding over the lower rail penetrate into Bores edge strips of the rubber membrane of the hose body and then holes in a top rail. With the help of nuts, the top rail and the bottom rail braced against each other, which is why there is a sealing compression of the two Membrane layers come between the rails.
- This amount of leakage water is undesirable because, on the one hand, the appearance of the filled tube body is adversely affected and in the winter the leakage water quantities on the back of the Hose weirs lead to ice formation.
- weirs are known in which vertically aligned side walls in a plan view of the hose weir not parallel to each other, but in the direction of flow considered to run towards each other. This also allows a certain improvement in Achieve wrinkling.
- the narrowing of the flow cross-section reduces the hydraulic performance of the weir.
- Side walls the direction of discharge into the underwater in an undesirable manner.
- the Overall width of the building increased again due to the inclination of the side walls.
- a property in known hose weirs is that when lowering form air-filled hose bodies, one or two kinks (V-corners).
- the spot, at which the air-filled hose weir bends is affected by the hydraulic conditions in the Inflow area and determined by the water load on the overflowed weir.
- a negative visual appearance (banana contour) also negative effects on the hydraulic stress of the banks below the Weir.
- Hose weirs provide recesses or depressions on the base of a weir body. This is to pull rubber material sideways away from the buckling point tighten the membrane material there and eliminate the kink. satisfactory
- the above-mentioned measures were successful with vertical side walls cannot be achieved.
- the invention has for its object to propose a hose weir in which the adverse effects of the side wall fold and the buckling point when lowering the weir are reducing.
- this task solved according to the invention in that the sole in at least near a side wall Direction towards this side wall increases, the increasing area in the flow direction considered at least over part of the width of a contact surface of the membrane extends.
- the tube body thus has on its top not an absolutely straight course, but with the beginning of the ascending towards the side wall Area also rises to the top of the tube body to the area of the side wall fold to sink again, but to a level above the upper edge in the middle Area.
- the hose weir according to the invention is thus complete even in the case of a full build-up tight.
- the rising area extends over the entire width which extends as a support surface for the membrane weir plate can only partially such extension when retrofitting existing hose weirs with a complete flat weir plate.
- wedge-shaped possibly also in the direction of flow bevelled support elements from the underwater side under the Membrane pushed and attached there.
- this plane is only in a direction perpendicular to the flow direction of the water, that is, be inclined in the longitudinal direction of the hose body.
- the inclined plane is in generally run with their contour lines parallel to the flow direction, as is the case with the middle horizontal section of the sole is also the case.
- the angle of inclination ⁇ is one Ramp, measured in relation to a horizontal plane, approx. 1 ° to 5 °, preferably 2 ° to 3 °, is.
- an ascending section be extends to a transition area from the sole into the side wall. It is preferred an embodiment in which a ramp-shaped area directly into a vertical side wall transforms. Especially in existing weir systems with former metal flaps as Such a procedure is particularly advantageous for stowage organs.
- the length of the increasing Section is about 1 meter to 6 meters, preferably about 2 meters to 4 meters.
- a hose weir 1 shown schematically in FIG. 1 has an elongated, transverse to Flow direction tubular body 2 and a bottom 3 of a body of water Support structure 4.
- the support structure 4 consists of reinforced concrete and includes two side walls 5 oriented perpendicular to the horizontally running sole 3, of which only one is shown for the sake of simplicity.
- the tubular body 2 consists of a rubber-elastic membrane, for example EPDM, and has a thickness of approximately 4 to 30 millimeters.
- the tube body 2 consists of a membrane 7 enclosing a cavity 6.
- the longitudinal edges of the membrane 7 overlap in the area of a lower fastening rail 9 and an upper fastening rail 10, with the help of embedded in the sole 3 anchors and nuts be clamped in a known manner and thus the cavity 6 inside the Seal the hose body 2 tightly.
- In the direction of flow (arrow 11) of the water in front of the Hose weir 1 forms an upper water level 12.
- Figure 4 there are also those on a vertical Sidewall portions of the top rail and a zig-zag end Z of the Hose body 2 shown.
- the side wall fold and the notch 16 result from the fact that the in FIG Mounting rails, not shown, on the one hand, along the entire length of the Sole 3 run between the side walls 5 and, on the other hand, starting from there, rising obliquely to the rear also along the surfaces 19 of the Extend side walls 5 to a point 20.
- These sloping on the side walls 5 Sections of the mounting rails provide a lateral seal of the Hose body 2 and are therefore indispensable.
- the disadvantage is due to the side wall connection however, "excess" rubber material is generated, which in the filled state of the Weir 1 leads to the known and undesirable wrinkling.
- FIG. 2 shows a hose weir 1 'which essentially has the same structure as that in FIG Figure 1 shown known hose weir matches.
- the technology shows the sole 3 in a section 21 in the form of a ramp 21 in the hose weir 1 ' at an angle ⁇ of approx. 3 ° to the horizontal.
- Section 21 goes from a central region 22 of the sole 3, and extends directly to the surface 19 of the vertically aligned side wall 5.
- a horizontally measured length of the Ascending section 21 of approximately 2 meters results in a height difference in the present case 23 between a point 24 at which the ramp begins and a point 25 at which the ramp merges into the side wall 5 of about 0.1 meters.
- an upper contour 26 of the hose body runs 2 above the central region 22 of the sole 3, initially horizontally, in order from one Point 27 at an angle ⁇ - measured with respect to a horizontal - in the direction of to climb the side wall 5.
- the angle ⁇ on the contour 26 is slightly smaller than the angle ⁇ in the area of the sole.
- FIG. 3 shows a top view of the hose weir 1 ', with arrow 11 again the flow direction is illustrated.
- the sole 3 of the holding structure has one middle region 22 and an adjoining ramp-like section 21, which extends to the side wall 5. In a direction parallel to that Viewed in the direction of flow (arrow 11), both the central region 22 and the ramp-shaped section 21 without an inclination to the horizontal. Alternatively, the central region 22 and / or the ramp-shaped section can also be such Show inclination in the direction of flow. Both the middle area 22 and the rising area Section 21 extend over a width 28. As can also be seen from FIG. 4, the sole 3 has a shallow depression in the area of the fastening rails 9 and 10.
- the surface 19 of the side wall 5 contains sections rising in the flow direction the fastening rails 9 and 10, which abut each other in the area of a corner 29. In the area of the transition from the middle area 22 into the ramp-shaped section 21 also encounter two sections of the fastening rails 9 and 10 at point 30 to each other, which can be mitered if necessary.
- FIG. 5 shows the holding structure 4 of the hose weir 1 'before the hose body 2 is fastened has been. Subsequent to the horizontal central region 22 of the sole 3 closes the ramp-shaped section 21, which extends up to the side wall 5. In front of the later attachment area of the hose body there is a continuous flat strip 31, if necessary by such an amount compared to the central area 22 is offset in height that the fastening rail on the side wall 5 highest point of the ramp is still covered by the raised strip 31.
- FIG. 6 shows an alternative variant of a hose weir 1 ′′, in which the sole starts out of a central region 22 initially has a lowered section 32 which from the point 33 it merges into a ramp-like region 21, which in turn changes extends to the surface 19 of the side wall 5.
- a height difference 34 between the level of the sole 3 in the middle region 22 and the lowest point the sole (at point 33) is approx. 0.05 meters smaller than the height difference 23 ", which is by the ramp-shaped rise, so that the sole at the point 25 '' immediately adjacent to the surface 19 of the side wall 5 above the level in the middle area 22 lies.
- the cavity 6 of the hose body 2 is filled as in the prior art known, with the help of suitable pressure media sources, such as pumps at a Water filling or compressors with an air filling.
- suitable pressure media sources such as pumps at a Water filling or compressors with an air filling.
- the filling / emptying and regulating devices for such hose weirs are generally known and in need no further explanation at this point.
