Description

Die Erfindung betrifft eine Muldenanordnung nach dem Oberbegriff des Anspruchs 1.The invention relates to a trough arrangement according to the preamble of claim 1.

Aus der US 5 735 637 A ist eine gattungsgemäße Muldenanordnung bekannt, bei der die einzelnen Muldenabschnitte aus mineralischen, organischen oder metallischen Werkstoffen bzw. Werkstoffgemischen bestehen können. Weiterhin ist aus der DE 20 2014 105 739 U1 ein Versickerungsrinnenelement bekannt, welches einen U-förmigen Rinnenkörper aus Beton aufweistFrom the US 5 735 637 A a generic trough arrangement is known in which the individual trough sections can consist of mineral, organic or metallic materials or material mixtures. Furthermore, from the DE 20 2014 105 739 U1 a percolation channel element is known which has a U-shaped channel body made of concrete

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Muldenanordnung dahingehend zu verbessern, dass diese eine hohe Tragfähigkeit bietet und eine zeitsparende, erleichterte Fertigstellung der Muldenanordnung ermöglicht.The invention has for its object to improve a generic trough arrangement in such a way that it offers a high load-bearing capacity and enables time-saving, easier completion of the trough arrangement.

Die Erfindung wird durch eine Muldenanordnung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The invention is achieved by a trough arrangement with the features of claim 1. Advantageous configurations are described in the subclaims.

Die Erfindung schlägt mit anderen Worten vor, unterhalb der Versickerungsmulde keine Rigole aus Kies oder einen ähnlich versickerungsfähigen Untergrund zu verwenden, sondern vielmehr ein Betonfundament. Auf diese Weise kann die Mulde erheblich höher als bislang üblich belastet werden, beispielsweise kann statt der Belastungsklasse D auch die Muldenanordnung entsprechend der Belastungsklassen E oder F ausgestaltet werden und beispielsweise das Überfahren mit LKWs gestatten.In other words, the invention proposes not to use a trench made of gravel or a similarly infiltrating subsoil below the infiltration trough, but rather a concrete foundation. In this way the trough can be considerable higher than usual, for example, instead of the load class D, the trough arrangement can be designed according to the load classes E or F and, for example, allow trucks to drive over it.

Da die Muldenanordnung üblicherweise in einem zuvor gezogenen Graben angeordnet wird und der Beton dann in den Graben eingeschüttet wird, besteht die Gefahr, dass die einzelnen Muldenabschnitte im Beton aufschwimmen und beispielsweise nicht seitlich vom Beton umschlossen werden können. Insbesondere wenn die Muldenabschnitte aus Kunststoff oder einem ähnlich leichtgewichtigen Material bestehen, muss sichergestellt werden, dass die Muldenabschnitte nicht im flüssigen, in den Graben eingefüllten Beton aufschwimmen. Vorschlagsgemäß ist daher eine Verlegehilfe vorgesehen, die einerseits in dem Betonfundament verankert ist und andererseits als Auftriebssicherung die Mulde übergreift.Since the trough arrangement is usually arranged in a previously drawn trench and the concrete is then poured into the trench, there is a risk that the individual trough sections float in the concrete and, for example, cannot be enclosed laterally by the concrete. In particular if the trough sections are made of plastic or a similar lightweight material, it must be ensured that the trough sections do not float in the liquid concrete filled in the trench. According to the proposal, a laying aid is therefore provided, which is anchored in the concrete foundation on the one hand and on the other hand overlaps the trough as a buoyancy protection.

Die Herstellung der vorschlagsgemäßen Muldenanordnung kann beispielsweise in zwei Abschnitten erfolgen, wobei im ersten Abschnitt zunächst ein Betonfundament geschaffen wird, in welchem die Verlegehilfen verankert werden. Das Betonfundament kann auf unterschiedliche, an sich bekannte Weise geschaffen werden: beispielsweise kann ein Sockel aus fließfähigem Beton gegossen werden, in den anschließend die Verlegehilfen eingesteckt werden, bevor der Beton abbindet, oder die Verlegehilfen können zunächst in den Boden eingesteckt werden, und anschließend wird der flüssige Beton zur Schaffung des Sockels auf den Untergrund gegossen und bewirkt dabei einen Formschluss mit den Verlegehilfen. Alternativ zur Verwendung von fließfähigem Beton kann eine sogenannte trockene Mischung bzw. erdfeuchte Mischung Verwendung finden, welche an die zunächst provisorisch aufgestellten Verlegehilfen angehäufelt wird und diese dann beim Abbinden festlegt.The trough arrangement according to the proposal can be produced, for example, in two sections, a concrete foundation first being created in the first section, in which the laying aids are anchored. The concrete foundation can be created in various ways known per se: for example, a base made of flowable concrete can be poured, into which the laying aids are then inserted before the concrete sets, or the laying aids can first be inserted into the ground and then The liquid concrete is poured onto the subsoil to create the base and thereby forms a positive connection with the laying aids. As an alternative to the use of flowable concrete, a so-called dry mix or earth-moist mix can be used, which is piled up on the provisional installation aids and then fixed when setting.

Wenn dieser erste Abschnitt den Verankerungshilfen einen ausreichenden Halt gibt, wird in einem zweiten Arbeitsgang das Betonfundament vervollständigt und beispielsweise fließfähiger Beton seitlich neben die Muldenabschnitte geschüttet, so dass eine stabile Stützschulter geschaffen wird, welche die hohe Belastbarkeit der Muldenabschnitte auch dann ermöglicht, wenn die Muldenabschnitte selbst beispielsweise aus Kunststoff bestehen.If this first section provides sufficient support for the anchoring aids, the concrete foundation is completed in a second work step and, for example, pourable concrete is poured to the side of the trough sections, so that a stable support shoulder is created which enables the trough sections to withstand high loads even when the trough sections even made of plastic, for example.

Die Verlegehilfe, die als Auftriebssicherung die Mulde hält, ist vorschlagsgemäß als Blechzuschnitt ausgestaltet. Auf diese Weise ist sehr wirtschaftlich die Herstellung der Verlegehilfe möglich. Zudem wird dadurch, dass ein flächiges Element verwendet wird, die Möglichkeit geschaffen, eine Soll-Bruchstelle innerhalb des Betonfundaments zu schaffen. Würde ansonsten der erwähnte Graben vollständig, d. h. über seine gesamte Länge, mit Beton befüllt, so würde ein sehr langes, monolithisches Betonbauwerk geschaffen, welches angesichts von Setzbewegungen oder ähnlichen Bodenbewegungen mit großer Wahrscheinlichkeit irgendwo reißen würde, und zwar in nicht kontrollierter Weise an unkontrollierten Stellen. Die als Blechplatten ausgestalteten Verlegehilfen bewirken automatisch eine Schwächung des Betonbauwerks, wenn sie sich über einen großen Anteil des Querschnitts erstrecken, der ansonsten von dem Beton ausgefüllt würde. Auf diese Weise wird bei auftretenden Erdbewegungen oder ähnlichen auf das Betonbauwerk einwirkenden Belastungen der Beton an diesen Schwächungslinien reißen, also an definierten, eigens dafür vorgesehenen Stellen.The laying aid, which holds the trough as a buoyancy protection, is designed as a sheet metal blank. In this way, the laying aid can be produced very economically. In addition, the fact that a flat element is used creates the possibility of creating a predetermined breaking point within the concrete foundation. Otherwise the mentioned trench would be complete, i. H. Along its entire length, filled with concrete, a very long, monolithic concrete structure would be created, which would most likely crack somewhere in view of setting movements or similar ground movements, in an uncontrolled manner at uncontrolled points. The laying aids designed as sheet metal plates automatically weaken the concrete structure if they extend over a large proportion of the cross section that would otherwise be filled by the concrete. In this way, the concrete will tear at these weakening lines in the event of earth movements or similar loads acting on the concrete structure, i.e. at defined, specially provided locations.

Vorschlagsgemäß ist weiterhin vorgesehen, dass die Verlegehilfen auch jeweils eine Dehnfuge in diesem monolithischen Betonbauwerk schaffen. Zu diesem Zweck weist die als Blechzuschnitt ausgestaltete Verlegehilfe auf einer oder auf beiden ihrer Oberflächen eine Schicht aus einem Schaumwerkstoff auf, insbesondere vorteilhaft aus einem expandierten Polystyrol. Der Schaumwerkstoff ist also so fest, dass er beim Einfüllen des Betons nicht in unerwünschtem Maße bereits verdichtet wird, aber er ist auf der anderen Seite auch so nachgiebig, dass er bei Expansionsbewegungen bzw. überhaupt bei Relativbewegungen zwischen den zwei aneinander angrenzenden Abschnitten des Betonbauwerks nachgeben und komprimiert werden kann.According to the proposal, it is also provided that the installation aids also each create an expansion joint in this monolithic concrete structure. For this purpose, the laying aid designed as a sheet metal blank has a layer made of a foam material on one or both of its surfaces, particularly advantageously made of expanded polystyrene. The foam material is so strong that it is not already compressed to an undesirable extent when the concrete is poured in, however on the other hand, it is also so flexible that it can yield and compress during expansion movements or at all relative movements between the two adjacent sections of the concrete structure.

In an sich bekannter Weise kann die Abdeckung oberhalb der Mulde aus Gusseisen bestehen, so dass die Abdeckung selbst eine ausreichende Stabilität aufweist, um die entsprechend hohen Belastungsklassen der gesamten Muldenanordnung zu ermöglichen. Die Kräfte von der Abdeckung können beispielsweise auf die beiden seitlichen Beton-Stützschultern abgetragen werden, so dass die aus Kunststoff bestehenden Muldenabschnitte selbst entweder vollständig von den Druckkräften, die von oben durch Fahrzeuge auf die Abdeckung einwirken, freigehalten werden können oder zumindest in einem lediglich geringen Maß belastet werden.In a manner known per se, the cover above the trough can consist of cast iron, so that the cover itself has sufficient stability to enable the correspondingly high load classes of the entire trough arrangement. The forces from the cover can be transferred, for example, to the two lateral concrete support shoulders, so that the trough sections made of plastic themselves can either be kept completely free of the pressure forces that act on the cover from above from vehicles, or at least in only a small amount Measure.

Unterhalb der Mulde kann in einer ersten Ausführungsform der Muldenanordnung eine Rinne verlaufen. Die Rinne kann in an sich üblicher Weise nach oben offen ausgestaltet sein, so dass sie oben eine Einlassöffnung für Wasser aufweist. Innerhalb der vorschlagsgemäßen Muldenanordnung kann eine solche Rinne unterhalb der Mulde derart angeordnet sein, dass diese Einlassöffnung der Rinne an die Ablauföffnung der Mulde anschließt, so dass das Wasser, welches aus der Versickerungsmulde nach unten gelangt, in die Rinne gelangt. Da die Rinne unten geschlossen ausgestaltet ist, ist mit dieser Ausgestaltung der Muldenanordnung die Möglichkeit gegeben, das Wasser mittels der Rinne an einen entfernten Ort zu leiten. Dies kann beispielsweise vorteilhaft sein, wenn die Muldenanordnung ohnehin in einem Boden vorgesehen ist, der nicht versickerungsfähig ist, beispielsweise in einem stark lehmhaltigen Boden. Oder es kann aus anderen Gründen gewünscht sein, kein Wasser von der Mulde in den umgebenden Boden versickern zu lassen, wie dies beispielsweise im Straßenbau der Fall sein kann, wenn das Einleiten von Wasser in den Unterbau der Straße nicht gewünscht ist, um die Tragfähigkeit dieses Unterbaus nicht zu gefährden.In a first embodiment of the trough arrangement, a trough can run beneath the trough. The channel can be designed in a manner which is conventional per se, so that it has an inlet opening for water at the top. Within the proposed trough arrangement, such a trough can be arranged below the trough in such a way that this inlet opening of the trough connects to the outlet opening of the trough, so that the water which comes down from the infiltration trough reaches the trough. Since the channel is designed to be closed at the bottom, this configuration of the trough arrangement enables the water to be conducted to a remote location by means of the channel. This can be advantageous, for example, if the trough arrangement is provided in any case in a soil that cannot be infiltrated, for example in a soil that contains a lot of clay. Or, for other reasons, it may be desirable not to allow water to seep away from the trough into the surrounding soil, as can be the case, for example, in road construction when discharge of water in the substructure of the road is not desired in order not to endanger the load-bearing capacity of this substructure.

In einer zweiten Ausgestaltung der Muldenanordnung kann vorgesehen sein, dass die Versickerungswirkung der Mulde beibehalten wird, obwohl unterhalb der Mulde das an sich für Wasser undurchlässige Betonfundament vorgesehen ist. Um dennoch eine Versickerung der Mulde zu ermöglichen, kann in diesem Fall vorteilhaft unterhalb der Ablauföffnung der Mulde ein Rohrstutzen angeordnet sein. Bei der Erstellung der Muldenanordnung kann in dem erwähnten Graben beispielsweise zunächst die Anordnung eines solchen Rohrstutzens vorgesehen sein, auf dem dann der Muldenabschnitt der Mulde so aufgelegt wird, dass die Ablauföffnung der Mulde über dem Rohrstutzen zu liegen kommt, wenn anschließend Beton in den Graben um den Rohrstutzen und die Mulde herum eingefüllt wird. So verhindert der Rohrstutzen, dass Beton unter die Ablauföffnung der Mulde fließt. Auf diese Weise ist sowohl eine Muldenanordnung mit einer hohen Tragfähigkeit geschaffen, wie sie das Betonfundament ermöglicht, als auch eine Mulde mit der an sich bei Mulden typischen Versickerungsfunktion, da der Rohrstutzen mit seinem nicht vom Beton ausgefüllten Freiraum eine Versickerungsöffnung unterhalb der Ablauföffnung der Mulde schafft, durch welche das aus der Mulde austretende Wasser in den darunter befindlichen Boden versickern kann.In a second embodiment of the trough arrangement it can be provided that the infiltration effect of the trough is maintained, although the concrete foundation, which is inherently impermeable to water, is provided below the trough. In order to nevertheless allow the trough to seep away, a pipe socket can advantageously be arranged in this case below the trough drain opening. When creating the trough arrangement, the arrangement of such a pipe socket, for example, can initially be provided in the mentioned trench, on which the trough section of the trough is then placed in such a way that the drain opening of the trough comes to lie above the pipe socket when concrete subsequently flows into the trench the pipe socket and the trough is filled around. In this way, the pipe socket prevents concrete from flowing under the drain opening of the trough. In this way, a trough arrangement with a high load-bearing capacity, as made possible by the concrete foundation, is created, as well as a trough with the infiltration function typical of troughs, since the pipe socket with its free space not filled with concrete creates an infiltration opening below the drain opening of the trough , through which the water emerging from the trough can seep into the ground below.

Die als Blechzuschnitt ausgestaltete Verlegehilfe weist unten einen spitz zulaufenden Erdspieß auf, so dass sie in den Boden des erwähnten Grabens eingestochen werden kann. Eine Höhenbegrenzung bzw. Tiefenbegrenzung, also ein Anschlag dafür, wie weit die Verlegehilfe in den Boden des Grabens eingesteckt werden kann, wird durch eine Bodenlasche gebildet, die als etwa U-förmige Stanzlinie innerhalb des Blechzuschnitts ausgestaltet ist, so dass die Bodenlasche einfach durch Umbiegen in eine um 90° gegenüber dem übrigen Blechzuschnitt abgewinkelte Position gebracht werden kann und somit bei Erreichen der gewünschten Eindringtiefe, mit welcher die Verlegehilfe in den Boden des Grabens eingesteckt wird, auf dem Boden zu liegen kommt.The laying aid, which is designed as a sheet metal blank, has a pointed earth spike at the bottom, so that it can be pierced into the bottom of the mentioned trench. A height limitation or depth limitation, i.e. a stop for how far the laying aid can be inserted into the bottom of the trench, is formed by a bottom flap which is designed as an approximately U-shaped punching line within the sheet metal blank, so that the bottom flap is simply bent over can be brought into a position angled by 90 ° with respect to the rest of the sheet metal blank and thus when it is reached the desired depth of penetration, with which the laying aid is inserted into the bottom of the trench, comes to lie on the floor.

Oberhalb der Bodenlasche, nämlich in der Weise, dass die Mulde von der Verlegehilfe übergriffen werden kann, bildet die Verlegehilfe eine Auftriebslasche, welche als Auftriebssicherung dient und einen seitlichen Vorsprung der Mulde übergreift. Beispielsweise kann im Fußbereich der Mulde eine Art Fußplatte vorgesehen sein, oder im Bereich der Seitenwände der Mulde können außen verlaufende Versteifungsrippen vorgesehen sein, die dementsprechend von den Auftriebslaschen der Verlegehilfen übergriffen werden können, so dass die gewünschte Auftriebssicherung mittels der Verlegehilfe bewirkt wird.Above the bottom flap, namely in such a way that the laying aid can overlap it, the laying aid forms a buoyancy flap which serves as a buoyancy protection and engages over a lateral projection of the trough. For example, a type of footplate can be provided in the foot area of the trough, or stiffening ribs running outside can be provided in the area of the side walls of the trough, which ribs can accordingly be overlapped by the buoyancy straps of the laying aids, so that the desired buoyancy protection is brought about by the laying aid.

Weiterhin können vorteilhaft die als Blechzuschnitte ausgestalteten Verlegehilfen so genannte Zentrierlaschen aufweisen, die der Mulde auf deren beiden Seiten anliegen, so dass die Mulde innerhalb der Verlegehilfe zentriert und geführt ist. Auf diese Weise ist sichergestellt, dass die Muldenabschnitte auch bei Einfüllen des Betons in den Graben zuverlässig ihre Position beibehalten und in der gewünschten Weise einzelne Muldenabschnitte aneinander anschließen, welche insgesamt die Mulde über ihre gesamte Länge bilden.Furthermore, the laying aids designed as sheet metal blanks can advantageously have so-called centering tabs which lie against the trough on both sides thereof, so that the trough is centered and guided within the laying aid. This ensures that the trough sections reliably maintain their position even when the concrete is poured into the trench and connect individual trough sections to one another in the desired manner, which overall form the trough over its entire length.

Ein Ausführungsbeispiel der Erfindung wird anhand der rein schematischen Darstellungen nachfolgend näher erläutert. Dabei zeigt

An exemplary embodiment of the invention is explained in more detail below on the basis of the purely schematic representations. It shows

a cross section through a trough arrangement, and
Fig. 2
a perspective view of two interconnected installation aids.

In den Zeichnungen ist mit 1 insgesamt eine Muldenanordnung bezeichnet, wobei eine Mulde 2 mit einem Substrat 3 gefüllt ist, welches eine mechanische bzw. physikalische und auch eine biologische Behandlung der in die Mulde 2 gelangenden Wässer ermöglicht. Die Mulde 2 weist oben eine über die gesamte Breite reichende Einlassöffnung 4 auf, die mit einer aus Gusseisen bestehenden Abdeckung 5 abgedeckt ist. Das in die Mulde 2 gelangende Wasser wird, nachdem es durch das Substrat 3 gelaufen ist, unten aus Auslassöffnungen 6 der Mulde 2 austreten, wobei diese Auslassöffnungen 6 jeweils von einem Ringkragen 7 umgeben sind, der einen gewissen Mindestwasserstand innerhalb der Mulde 2 sicherstellt, um auch über längere Trockenperioden die Mikrolebewesen im Substrat 3 lebensfähig zu halten.In the drawings, 1 generally designates a trough arrangement, a trough 2 being filled with a substrate 3, which has a mechanical or physical and also a biological one Treatment of the water entering the trough 2 is made possible. The trough 2 has an inlet opening 4 which extends over the entire width and is covered with a cover 5 made of cast iron. The water entering the trough 2, after it has passed through the substrate 3, will exit from the outlet openings 6 of the trough 2 below, these outlet openings 6 each being surrounded by an annular collar 7, which ensures a certain minimum water level within the trough 2 to keep the microorganisms in the substrate 3 viable even over longer dry periods.

Um die Mulde 2 herum verläuft Beton, der seitlich neben der Mulde 2 zwei Stützschultern 8 bildet, auf denen die Abdeckung 5 abgestützt ist. Unterhalb der Mulde 2 verläuft eine halbrunde, nach oben offene Rinne 9 unterhalb der Auslassöffnungen 6, so dass bei dieser Ausgestaltung der Muldenanordnung 1 eine nach unten flüssigkeitsdichte Ausgestaltung bewirkt wird und das aus der Mulde 2 austretende Wasser durch die Rinne 9 an eine gewünschte Stelle abgeleitet werden kann.Concrete runs around the trough 2, which forms two support shoulders 8 on the side next to the trough 2, on which the cover 5 is supported. Below the trough 2 there is a semicircular, upwardly open channel 9 below the outlet openings 6, so that in this embodiment of the trough arrangement 1 a downwardly liquid-tight configuration is achieved and the water emerging from the trough 2 is drained through the channel 9 to a desired location can be.

Abweichend von dem dargestellten Ausführungsbeispiel kann unterhalb der Auslassöffnungen 6 ein Rohrabschnitt angeordnet sein, der eine nach unten führende Versickerungsöffnung schafft. Unterhalb der Mulde 2 ist ebenfalls Beton vorgesehen, wobei der Beton hier als Betonfundament 11 bezeichnet ist, welches auf einen Boden 10 gegossen ist. Die erwähnten Rohrabschnitte, die sich an Stelle der Rinne 9 unterhalb der Auslassöffnungen 6 befinden könnten, würden auf den Boden 10 aufstehen und sich bis an die Unterseite der Mulde 2 erstrecken.In a departure from the exemplary embodiment shown, a pipe section can be arranged below the outlet openings 6, which creates an infiltration opening leading downwards. Concrete is also provided below the trough 2, the concrete here being referred to as the concrete foundation 11, which is poured onto a floor 10. The pipe sections mentioned, which could be in place of the channel 9 below the outlet openings 6, would stand on the floor 10 and extend to the underside of the trough 2.

In Fig. 1 ist weiterhin eine Verlegehilfe 14 ersichtlich, die als flacher Blechzuschnitt ausgestaltet ist, welcher beispielsweise mittels eines Lasers oder durch einen Stanzvorgang aus einer größeren Blechtafel herausgetrennt ist. Die Verlegehilfe 14 weist unten zwei Erdspieße 15 auf und etwa auf Höhe des oberen Endes der Erdspieße 15, bei dem dargestellten Ausführungsbeispiel geringfügig darüber, sind bogenförmige Aussparungen ersichtlich, die als U-förmige Stanzlinien ausgestaltet sind und Bodenlaschen 16 umgeben. Die Bodenlaschen 16 sind aus dem Blechzuschnitt der Verlegehilfe 14 herausgebogen worden in eine liegende Ausrichtung, so dass sie als Anschlag dienen, bis zu welchem die Verlegehilfe 14 in den Boden 10 eingesteckt werden kann.In Fig. 1 a laying aid 14 can also be seen, which is designed as a flat sheet metal blank, which is cut out of a larger sheet metal sheet, for example by means of a laser or by a punching process. The laying aid 14 has two ground spikes 15 at the bottom and approximately at the level of the upper end of the ground spikes 15, in the illustrated embodiment slightly above, arcuate recesses can be seen, which are designed as U-shaped punching lines and surround bottom flaps 16. The bottom flaps 16 have been bent out of the sheet metal blank of the laying aid 14 into a lying orientation, so that they serve as a stop, up to which the laying aid 14 can be inserted into the floor 10.

Oberhalb der Bodenlaschen 16 weist die Verlegehilfe 14 Aussparungen zur Aufnahme der - im Querschnitt beispielsweise rechteckigen oder halbrunden - Rinne 9 sowie der Mulde 2 auf. Oberhalb von seitlichen Aussteifungsrippen, welche die Mulde 2 aufweist, sind Auftriebslaschen 17 der Verlegehilfe 14 vorgesehen, die die Aussteifungsrippen übergreifen und somit die Mulde 2 gegen Auftrieb sichern.Above the bottom flaps 16, the laying aid 14 has cutouts for receiving the channel 9, which is rectangular or semicircular in cross section, and the trough 2. Above lateral stiffening ribs, which the trough 2 has, lifting tabs 17 of the laying aid 14 are provided, which overlap the stiffening ribs and thus secure the trough 2 against buoyancy.

Oberhalb der Auftriebslaschen 17 bildet die Verlegehilfe 14 schließlich noch Zentrierlaschen 18 aus, welche seitlich bis an die Mulde 2 heranreichen, und zwar bei dem dargestellten Ausführungsbeispiel bis an aufrecht verlaufende Vorsprünge, welche ebenfalls zur Aussteifung der Wände der Mulde 2 dienen.Above the buoyancy straps 17, the laying aid 14 finally forms centering straps 18, which reach laterally up to the trough 2, in the exemplary embodiment shown up to upright projections, which also serve to stiffen the walls of the trough 2.

In Fig. 2 sind zwei Verlegehilfen 14 in einer perspektivischen Anordnung dargestellt. Dabei ist ersichtlich, dass zwei benachbarte Bodenlaschen 16 in unterschiedlichen Richtungen aus dem Blechzuschnitt abgewinkelt sind.In Fig. 2 two laying aids 14 are shown in a perspective arrangement. It can be seen that two adjacent base plates 16 are angled in different directions from the sheet metal blank.

Weiterhin ist aus Fig. 2 ersichtlich, dass die beiden benachbarten Verlegehilfen 14 durch Distanzstreben 19 in einem vorgegebenen Abstand zueinander gehalten sind.Furthermore is off Fig. 2 it can be seen that the two adjacent laying aids 14 are held at a predetermined distance from one another by spacer struts 19.
