Description

Die vorliegende Erfindung betrifft ein Rinnenelement umfassend einen U-förmigen Rinnenkörper aus Beton oder Polymerbeton, wobei die beiden vertikalen Schenkel des Rinnenkörpers die Seitenwände bilden, die über einen Rinnenboden verbunden sind, der den horizontalen Abschnitt des Rinnenkörpers bildet. Der Rinnenkörper schließt einen Wasserlauf ein, und am oberen Ende der Seitenwände ist eine Rinnenabdeckung gehalten.The present invention relates to a channel element comprising a U-shaped channel body made of concrete or polymer concrete, the two vertical legs of the channel body forming the side walls which are connected via a channel bottom which forms the horizontal section of the channel body. The gutter body includes a watercourse and a gutter cover is supported at the top of the side walls.

Es ist Aufgabe der Erfindung, ein Rinnenelement zu schaffen, das eine effektive Reinigung des in das Rinnenelement einfließenden Wassers realisiert.The object of the invention is to create a channel element which realizes an effective cleaning of the water flowing into the channel element.

Diese Aufgabe wird durch ein Rinnenelement mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved by a channel element with the features of claim 1. Advantageous further developments of the invention are the subject matter of the dependent claims.

Gemäß der Erfindung ist in dem oben beschriebenen Rinnenelement zwischen den Seitenwänden eine wasserdurchlässige, z.B. poröse Platte angeordnet, die sich zumindest in etwa horizontal erstreckt. Die wasserdurchlässige Platte ist vorzugsweise an der Innenseite der Seitenwände gehalten. Sie kann auch durch zusätzliche Aufstandsflächen auf dem Rinnenboden gehalten werden. Auf der wasserdurchlässige Platte ist ein Filtersubstrat zum Beispiel einer offenen Schüttung angeordnet. Durch diese erfindungsgemäße Ausbildung des Rinnenelements wird das Rinnenelement in einen oberen Einlaufbereich unterteilt, in einen mittleren Filterbereich, der durch die Kombination des Filtersubstrats und der poröse Platte gebildet ist, und in einen unteren Abflussbereich unterhalb der poröse Platte, der zum Abführen des Wassers ausgebildet ist. Durch die Tatsache, dass auf der wasserdurchlässigen Platte das Filtersubstrat angeordnet ist, werden zum einen Schwimm- und Schwebstoffe und auch Schadstoffe abgefiltert, was dazu beiträgt, dass das Wasser zumindest teilgereinigt wird und andererseits die wasserdurchlässige Platte ihre Porosität beibehält und nicht durch die einfließenden Schwebstoffe verstopft. Durch die Tatsache, dass die wasserdurchlässige Platte im Wesentlichen aus dem gleichen Grundmaterial wie der Rinnenkörper besteht, nämlich aus Beton, gibt es keine Korrosionsprobleme, selbst wenn sich der Innenraum des Rinnenelements ständig unter Feuchtigkeit befindet und auch keine Temperaturbedingten Spannungen im Material. Das erfindungsgemäße Rinnenelement erzielt eine gute Reinigungswirkung mit einem geringen herstellungstechnischen Aufwand.According to the invention, in the above-described channel element between the side walls a water-permeable, e.g. arranged porous plate which extends at least approximately horizontally. The water-permeable plate is preferably held on the inside of the side walls. It can also be held on the channel floor by additional contact areas. A filter substrate, for example an open bed, is arranged on the water-permeable plate. This inventive design of the channel element divides the channel element into an upper inlet area, a central filter area, which is formed by the combination of the filter substrate and the porous plate, and a lower drainage area below the porous plate, which is designed to discharge the water . Due to the fact that the filter substrate is arranged on the water-permeable plate, on the one hand floating and suspended matter as well as pollutants are filtered off, which contributes to the fact that the water is at least partially cleaned and, on the other hand, the water-permeable plate maintains its porosity and not due to the flowing in suspended matter clogged. Due to the fact that the water-permeable plate consists essentially of the same basic material as the channel body, namely concrete, there are no corrosion problems, even if the interior of the channel element is constantly under moisture and there are also no temperature-related stresses in the material. The channel element according to the invention achieves a good cleaning effect with little manufacturing effort.

Unter "wasserdurchlässige Platte" wird in dieser Anmeldung eine Platte mit einem kf- oder Durchgangswert - auch Durchlässigkeitsbeiwert genannt - höher als 0,0001 m/s verstanden. Vorzugsweise liegt der kf-Wert zwischen 0,0001 m/s, insbesondere 0,0005 m/s und 0,01 m/s. Der Durchgangswert selbst ist unter DIN 18130-1 definiert.In this application, “water-permeable plate” is understood to mean a plate with a kf or passage value - also called the permeability coefficient - higher than 0.0001 m / s. The kf value is preferably between 0.0001 m / s, in particular 0.0005 m / s and 0.01 m / s. The passage value itself is defined under DIN 18130-1.

Die wasserdurchlässige Platte ist vorzugsweise eine Drainbetonplatte. Als Drainbeton wird ein Beton mit einer offenen Porosität die zu dem bezeichneten Durchgangswert führt. Die wasserdurchlässige Platte kann auch aus Blähton, poröser Keramik und anderen nicht korrodierenden, porösen Materialien bestehen. Es können so zum Beispiel auch poröse Materialien aus (Edel)metall oder Kunststoff oder Hybridmaterialien verwendet werden, die den oben spezifizierten Durchgangswert aufweisen.The water-permeable plate is preferably a drain concrete plate. A concrete with an open porosity that leads to the specified passage value is called drain concrete. The water-permeable plate can also not be made of expanded clay, porous ceramic and others corrosive, porous materials. For example, porous materials made of (precious) metal or plastic or hybrid materials can also be used, which have the passage value specified above.

Unter dem Begriff "Platte" wird ein flächiges planes oder dreidimensional geformtes Element verstanden, dessen Steifheit oder Tragfähigkeit groß genug ist, die mit Wasser gesättigte Filtersubstratschüttung, eventuell mit Einsatz zu tragen, wobei hinsichtlich der Tragfähigkeit nach Anforderungen ein Sicherheitsfaktor berücksichtigt werden kann.The term "plate" is understood to mean a flat, planar or three-dimensional element, the rigidity or load-bearing capacity of which is large enough to carry the water-saturated filter substrate fill, possibly with use, whereby a safety factor can be taken into account with regard to the load-bearing capacity according to requirements.

Vorzugsweise ist zur Erhöhung des Schadstoffrückhaltes und Schutz der wasserdurchlässigen Platte vor Kolmation durch eindringendes Filtersubstrat zusätzlich ein Filtervlies zwischen der Filtersubstratschüttung und der wasserdurchlässigen Platte angeordnet. Das Rinnenelement behält somit eine lange Funktionsfähigkeit, bevor ein Austausch des Substrats oder der wasserdurchlässigen Platte notwendig wird.In order to increase the retention of pollutants and to protect the water-permeable plate from colmation by penetrating filter substrate, a filter fleece is additionally arranged between the filter substrate bed and the water-permeable plate. The channel element thus retains a long functionality before an exchange of the substrate or the water-permeable plate becomes necessary.

In einer vorteilhaften Weiterbildung der Erfindung haben die beiden Seitenwände nach unten zum Wasserlauf hin einen geringeren Abstand als an der oberen Hälfte des Rinnenelements und die wasserdurchlässige Platte liegt mit ihren seitlichen einander abgewandten Endflächen gegen die Seitenwände an und wird dadurch gehalten. Auf diese Weise ist keine zusätzliche Halterung für die wasserdurchlässige Platte in dem Rinnenkörper notwendig, da diese allein durch den sich nach unten verengenden Querschnitt des Innenraums des Rinnenkörpers gehalten wird. Diese Ausführungsform ist herstellungstechnisch leicht realisierbar und mechanisch unanfällig.In an advantageous development of the invention, the two side walls have a smaller distance down to the watercourse than on the upper half of the channel element and the water-permeable plate rests against the side walls with its lateral end faces facing away from each other and is thereby held. In this way, no additional holder is necessary for the water-permeable plate in the channel body, since it is held solely by the downwardly narrowing cross section of the interior of the channel body. This embodiment can be easily implemented in terms of production technology and is mechanically insusceptible.

Vorzugsweise beträgt im Anlagebereich der wasserdurchlässigen Platte an den Seitenwänden die Stärke der Seitenwände wenigstens ein Viertel, vorzugsweise wenigstens 30% der Gesamtbreite der Rinne, wobei hier die aufsummierte Stärke der beiden Seitenwände gemeint ist. Dieses Merkmal stellt sicher, dass der Rinnenkörper stark genug ist, um die Aufspreizkräfte, die durch die endseitige Anlage der wasserdurchlässigen Platte gegen die Seitenwände auftritt, auffangen zu können.In the contact area of the water-permeable plate on the side walls, the thickness of the side walls is preferably at least a quarter, preferably at least 30% of the total width of the channel, which means here the total thickness of the two side walls. This feature ensures that the channel body is strong enough to be able to absorb the expansion forces that occur due to the end-side contact of the water-permeable plate against the side walls.

Vorzugsweise ist der Rinnenkörper stahlbewehrt, in welchem Fall der Rinnenkörper stark genug ist, den durch ein Einklemmen der wasserdurchlässigen Platte zwischen den Seitenwänden eingeleiteten Druck problemlos aufnehmen zu können. Zudem wird hierdurch zusammen mit der massiven Ausbildung, d.h. dem Verhältnis der Stärke der Seitenwände zur Rinnenbreite, das Rinnenelement auch für hohe Lasten geeignet.The channel body is preferably steel-reinforced, in which case the channel body is strong enough to be able to absorb the pressure introduced by clamping the water-permeable plate between the side walls without any problems. In addition, this, together with the massive training, i.e. the ratio of the thickness of the side walls to the channel width, the channel element is also suitable for high loads.

In einer vorteilhaften Weiterbildung der Erfindung weist das Rinnenelement eine Aufschwemmsicherung auf, die unterhalb des Anlagebereichs der wasserdurchlässigen Platte an den Seitenwänden angeordnet ist. Auf diese Weise ist die Aufschwemmsicherung, die eine Verstärkung des Rinnenkörpers bildet, gleichzeitig dazu konzipiert, die Stabilität des Rinnenkörpers gegen ein Aufspreizen aufgrund der durch die wasserdurchlässige Platte eingebrachten Kräfte zu unterbinden.In an advantageous development of the invention, the channel element has a float protection which is arranged below the contact area of the water-permeable plate on the side walls. In this way, the float protection, which forms a reinforcement of the channel body, is designed at the same time to prevent the stability of the channel body from spreading due to the forces introduced by the water-permeable plate.

Vorzugsweise ist an den oberen Enden der Seitenwände jeweils eine Metallzarge zur Aufnahme einer Rinnenabdeckung angeordnet, die mit Metallankern im Beton verankert ist. Auf diese Weise kann eine Rinnenabdeckung sicher auf den Seitenwänden aus Beton oder Polymerbeton gehalten werden. Statt der Metallzarge, die insbesondere aus verzinktem Stahl, Edelstahl oder Guss besteht, kann auch eine Kunststoffzarge oder Betonzarge zur Aufnahme der Rinnenabdeckung verwendet werden.A metal frame for receiving a channel cover is preferably arranged at the upper ends of the side walls, and is anchored in the concrete with metal anchors. In this way, a gutter cover can be securely held on the concrete or polymer concrete side walls. Instead of the metal frame, which in particular consists of galvanized steel, stainless steel or cast iron, a plastic frame or concrete frame can also be used to hold the channel cover.

In einer vorteilhaften Ausführungsform der Erfindung hat die wasserdurchlässige Platte eine Stärke zwischen 2 und 8 cm, insbesondere zwischen 3 und 5 cm. Diese Stärke ist gut geeignet, um die auf der wasserdurchlässigen Platte angeordnete Filtersubstratschüttung wirkungsvoll zu halten und ist andererseits gering genug, um nicht das Gewicht der Gesamtrinne übermäßig anzuheben und eine unnötige vertikale Erstreckung des Rinnenraums zu vermeiden. Zum anderen erlaubt diese Stärke der wasserdurchlässigen Platte einen ungehinderten Wasserdurchtritt von der Unterseite des Filtersubstrats zum unter der wasserdurchlässigen Platte befindlichen Wasserlauf, was oben in Bezug auf die Porosität bzw. den kf-Wert bereits ausgeführt wurde.In an advantageous embodiment of the invention, the water-permeable plate has a thickness between 2 and 8 cm, in particular between 3 and 5 cm. This thickness is well suited to effectively holding the filter substrate bed arranged on the water-permeable plate and, on the other hand, is small enough not to excessively increase the weight of the entire channel and to avoid unnecessary vertical extension of the channel space. On the other hand, this thickness of the water-permeable plate allows an unimpeded passage of water from the underside of the filter substrate to the watercourse located under the water-permeable plate, which has already been explained above with regard to the porosity or the kf value.

Vorzugsweise ist die wasserdurchlässige Platte plan, was herstellungstechnisch einfach zu realisieren ist und wenig Platz in dem Rinnenelement benötigt. In einer anderen bevorzugten Ausführungsform ist die wasserdurchlässige Platte teilkreiszylindrisch ausgebildet, wobei sich das Zentrum des Kreises mittig parallel zur Längsachse des Rinnenelements und unterhalb der wasserdurchlässigen Platte erstreckt. Die wasserdurchlässige Platte ist damit nach oben hin ausgebaucht und kann somit die Tragkräfte des Filtersubstrats besser aufnehmen.The water-permeable plate is preferably flat, which is easy to implement in terms of production technology and requires little space in the channel element. In another preferred embodiment, the water-permeable plate has a partially circular cylindrical design, the center of the circle extending centrally parallel to the longitudinal axis of the channel element and below the water-permeable plate. The water-permeable plate is thus bulged towards the top and can thus better absorb the load-bearing forces of the filter substrate.

Vorzugsweise beträgt in diesem Fall der Radius des Kreises zwischen 30 und 100 cm, insbesondere zwischen 35 und 70 cm, was zum einen die Tragkraft der Platte verbessert und zum einen die Höhenzunahme aufgrund der Zylinderform der wasserdurchlässigen Platte in Grenzen hält.In this case, the radius of the circle is preferably between 30 and 100 cm, in particular between 35 and 70 cm, which on the one hand improves the load-bearing capacity of the plate and on the one hand keeps the increase in height due to the cylindrical shape of the water-permeable plate within limits.

Vorzugsweise ist das Filtersubstrat eine Filtersubstratschüttung, die entweder lose oder vorzugsweise in einem Einsatz, z.B. einem permeablen Behälter oder einem Gewebesack auf der wasserdurchlässigen Platte angeordnet sein kann. Die Verwendung eines Einsatzes hat den Vorteil, dass für einen Austausch das gesamte Filtersubstrat durch Anheben des Einsatzes ausgewechselt werden kann.Preferably the filter substrate is a bed of filter substrate which is either loose or preferably in an insert, e.g. a permeable container or a fabric bag can be arranged on the water-permeable plate. The use of an insert has the advantage that the entire filter substrate can be exchanged for an exchange by lifting the insert.

Vorzugsweise hat das Filtersubstrat eine Höhe zwischen 5 und 35 cm, insbesondere zwischen 10 und 20 cm. Auf diese Weise wird zum einen eine gute Filterwirkung erzielt und zum anderen wird die Höhe des Rinnenelements nicht ungebührlich vergrößert.The filter substrate preferably has a height between 5 and 35 cm, in particular between 10 and 20 cm. In this way, on the one hand, a good filter effect is achieved and, on the other hand, the height of the channel element is not increased unduly.

Die Erfindung betrifft in gleicher Weise eine Rinne gebildet aus einer Mehrzahl stirnseitig aneinander gesetzter Rinnenelemente, wie sie oben beschrieben sind. Zwischen den Stirnseiten der Rinnenelemente, die vorzugsweise komplementär zueinander ausgebildet sind, können noch Dichtungen angeordnet sein, die die U-profilförmigen Rinnenkörper stirnseitig gegeneinander abdichten.The invention relates in the same way to a channel formed from a plurality of channel elements placed one on top of the other, as described above. Seals can also be arranged between the end faces of the channel elements, which are preferably designed to be complementary to one another, which seal the U-profile-shaped channel bodies against one another at the front.

Folgende Ausdrücke werden synonym verwendet: Abstand der Seitenwände - lichte Innenweite des Rinnenelements; Rinnenabdeckung - Einlaufrost; wasserdurchlässige Platte - poröse Platte - Drainbetonplatte; Durchgangswert - kf-Wert - Durchlässigkeitsbeiwert;The following expressions are used synonymously: distance between the side walls - clear inside width of the channel element; Gutter cover - inlet grate; water-permeable slab - porous slab - drain concrete slab; Passage value - kf-value - permeability coefficient;

Fig. 1 zeigt ein Rinnenelement 10 umfassend einen Rinnenkörper 12 in Form eines U-Profils mit zwei vertikalen Seitenwänden 14, 16 und einem diese verbindenden horizontalen Rinnenboden 18, auf welchem sich der Wasserlauf 20 des Rinnenelements 10 befindet. Auf den Oberseiten der beiden Seitenschenkel 14, 16 ist jeweils eine Zarge 22 vorzugsweise mit Stahlankern befestigt, die eine Rinnenabdeckung 24 insbesondere aus Gusseisen aufnehmen. Der lichte Abstand d zwischen den beiden Seitenschenkeln 14, 16 verringert sich von oben nach unten, was dazu führt, dass eine vorzugsweise plane wasserdurchlässige Platte 26, die hier vorzugsweise als Drainbetonplatte ausgebildet ist, durch den sich verengenden Innenquerschnitt (lichte Weite d) mit seinen seitlichen Endflächen 28 gegen die Innenseiten 31 der Seitenwände 14, 16 anliegt. Auf diese Weise wird die plane Drainbetonplatte 26 wirkungsvoll in einer horizontalen Position gehalten. Auf der wasserdurchlässigen Platte 26, welche vorzugsweise eine Stärke zwischen 2 und 8 cm, insbesondere zwischen 3 und 5 cm, hat, ist eine Filtersubstratschüttung 30 angeordnet, die entweder als lose Schüttung ausgebildet sein kann oder in einem Einsatz angeordnet sein kann, der dazu konzipiert ist, die Filtersubstratschüttung als Ganzes aus dem Rinnenelement von der Drainbetonplatte 26 abzuheben, zum Beispiel um diese zu reinigen oder auszuwechseln. Das dargestellte Konzept des Rinnenelements erlaubt eine günstige Herstellung einer Filterrinne mit guten Filtereigenschaften und einer guten Stabilität. Im Bereich der Anlage der Drainbetonplatte 26 an den Seitenwänden 14, 16 ist die aufsummierte Stärke 2 • x der beiden Seitenwände wenigstens 20%, insbesondere wenigstens 25% und vorzugsweise in wenigstens 30% und maximal 50%, vorzugsweise maximal 40% der Gesamtbreite B des Rinnenelements 10. Die beiden Seitenwände 14, 16 weisen am unteren Ende des Rinnenelements 10 Aufschwemmsicherungen 32 auf, welche neben ihrer Funktion als Aufschwemmsicherung durch die damit verbundene Zunahme der Stärke der Seitenwände 14, 16 an deren Außenseiten zusätzlich die durch die Drainbetonplatte 26, 34 eingebrachten Aufspreizkräfte abfangen. Fig. 1 shows a channel element 10 comprising a channel body 12 in the form of a U-profile with two vertical side walls 14, 16 and a horizontal channel bottom 18 connecting these, on which the watercourse 20 of the channel element 10 is located. On the upper sides of the two side legs 14, 16 a frame 22 is fastened, preferably with steel anchors, which receive a channel cover 24, in particular made of cast iron. The clear distance d between the two side legs 14, 16 decreases from top to bottom, which means that a preferably flat, water-permeable plate 26, which is preferably designed as a drain concrete plate here, through the narrowing inner cross-section (clear width d) with its lateral end faces 28 against the inner sides 31 of the side walls 14, 16. In this way, the flat drain concrete slab 26 is effectively held in a horizontal position. On the water-permeable plate 26, which preferably has a thickness between 2 and 8 cm, in particular between 3 and 5 cm, a filter substrate fill 30 is arranged, which can either be designed as a loose fill or can be arranged in an insert designed for this purpose is to lift the filter substrate bed as a whole from the channel element from the drain concrete slab 26, for example in order to clean or replace it. The concept of the channel element shown allows a cheap production of a filter channel with good filter properties and good stability. In the area where the drain concrete slab 26 rests on the side walls 14, 16, the total thickness 2 x of the two side walls is at least 20%, in particular at least 25% and preferably at least 30% and at most 50%, preferably at most 40% of the total width B des Channel element 10. The two side walls 14, 16 have anti-flooding devices 32 at the lower end of the channel element 10, which in addition to their function as anti-flooding devices, due to the associated increase in the thickness of the side walls 14, 16 on their outer sides, additionally those introduced by the drain concrete slab 26, 34 Intercept the expansion forces.

Fig. 2 zeigt eine zu Fig. 1 nahezu identische Ausführungsform mit dem Unterschied, dass die Drainbetonplatte 34 dort teilkreiszylindrisch ausgebildet ist, wodurch eine bessere Tragfähigkeit hinsichtlich der Filtersubstratschüttung 30 besteht. Die Filtersubstratschüttung 30 hat auch in Fig. 1 vorzugsweise eine Höhe h zwischen 10 und 30 cm, vorzugsweise zwischen 15 und 25 cm. Der Radius r der Drainbetonplatte 34 beträgt vorzugsweise zwischen 30 cm und 100 cm, vorzugsweise zwischen 40 und 70 cm. Auf diese Weise wird die Tragkraft der Drainbetonplatte verbessert und andererseits die mit der Ausbauchung verbundene Höhenzunahme der Platte begrenzt. Fig. 2 shows one to Fig. 1 Almost identical embodiment with the difference that the drain concrete slab 34 is formed there in a partially circular cylindrical shape, as a result of which there is better load-bearing capacity with regard to the filter substrate fill 30. The filter substrate fill 30 also has in Fig. 1 preferably a height h between 10 and 30 cm, preferably between 15 and 25 cm. The radius r of the drain concrete slab 34 is preferably between 30 cm and 100 cm, preferably between 40 and 70 cm. In this way, the load-bearing capacity of the drain concrete slab is improved and, on the other hand, the increase in height of the slab associated with the bulge is limited.

Es ist für den Fachmann offensichtlich, dass die Erfindung nicht auf die dargestellten Ausführungsbeispiele begrenzt ist, sondern innerhalb des Schutzbereichs der beiliegenden Ansprüche variiert werden können.It is obvious to a person skilled in the art that the invention is not limited to the exemplary embodiments shown, but that it can be varied within the scope of the appended claims.
