Description

"Drainage-Tank mit Spülrohr""Drainage tank with flushing pipe"

Die Erfindung betrifft einen Drainage-Tank nach dem Oberbeg- riff des Anspruchs 1.The invention relates to a drainage tank according to the preamble of claim 1.

Aus der EP 1 260 640 A1 sind derartige Drainage-Tanks bekannt. Schmutzpartikel, die mit dem Wasser in die Rigole eingetragen werden, können ggf. über einen Zeitraum von mehreren Jahren zu einer „Versandung" des unteren Bereichs der Rigole führen. Bei einer lediglich in der Tankwand vorgesehenen Einlassöffnung trägt das in den Tank einströmende Wasser Sedimente mit sich, die Undefiniert im Tank verteilt werden und sich an schlecht zugänglichen Stellen absetzen können. Im Vergleich dazu wird durch das sich in den Tank erstreckende Rohr ein definierter Bereich geschaffen, in dem sich die Sedimente absetzen können.Such drainage tanks are known from EP 1 260 640 A1. Dirt particles, which are introduced into the trench with the water, can possibly lead to a "sanding" of the lower area of the trench over a period of several years. With an inlet opening provided only in the tank wall, the water flowing into the tank carries sediments with it that are distributed undefined in the tank and can settle in hard-to-reach places. In comparison, the pipe extending into the tank creates a defined area in which the sediments can settle.

Der Erfindung liegt die Aufgabe zugrunde, einen Drainage-Tank zu schaffen, der auch über einen großen Zeitraum problemlos, mit möglichst geringem Wartungsaufwand, sedimentfrei gehalten werden kann.The invention has for its object to provide a drainage tank that can be kept sediment-free over a long period of time, with as little maintenance as possible.

Diese Aufgabe wird durch einen Drainage-Tank mit den Merk- malen des Anspruchs 1 gelöst. Die Erfindung schlägt mit anderen Worten vor, den Drainage- Tank mit einem Rohr zu versehen, durch welches das Wasser in den Tank eingeleitet wird. Das Wasser verlässt das Rohr dabei über entsprechende Durchtrittsöffnungen, die in einem oberen Abschnitt der Rohrwandung vorgesehen sind, während ggf. imThis object is achieved by a drainage tank with the features of claim 1. In other words, the invention proposes to provide the drainage tank with a pipe through which the water is introduced into the tank. The water leaves the pipe through corresponding through openings, which are provided in an upper section of the pipe wall, while possibly in

Wasser vorhandene Verunreinigungen sedimentieren und im unteren, wannenartig geschlossenen Abschnitt des Rohrquerschnittes zurückgehalten werden. Die Sedimente gelangen also nicht oder lediglich zu einem erheblich reduzierten Anteil in den Bereich des Tanks, der außerhalb des Rohrs liegt. Das Rohr kann in regelmäßigen Abständen durchspült werden. Es wirkt dabei mit seinem unteren, geschlossenwandigen Abschnitt als Rinne, so dass zusammen mit der Spülflüssigkeit die Sedimente aus dem Rohr und damit aus dem Drainage-Tank ausgetragen werden.Water sediments contaminate and be retained in the lower, tub-like section of the pipe cross-section. The sediments therefore do not reach the tank area, or only to a considerably reduced extent, which is outside the pipe. The pipe can be flushed through at regular intervals. It acts with its lower, closed-walled section as a gutter, so that the sediments are discharged from the pipe and thus from the drainage tank together with the flushing liquid.

Vorteilhaft kann das Rohr den Tank durchsetzen und ein Muffen- und ein Spitzende aufweisen, wobei wenigstens eines dieser beiden Enden über die übrigen Abmessungen des eigentli- chen Drainage-Tanks vorsteht. Auf diese Weise kann eine Koppelung zweier gleichartiger Drainage-Tanks dadurch erfolgen, dass die beiden Rohre dieser beiden Tanks in an sich bekannter Weise mit Muffen- und Spitzende miteinander verbunden werden, so dass insgesamt die beiden Rohre ein längeres Gesamt- röhr bilden. Der aus mehreren Einzeltanks gebildete gesamteThe tube can advantageously pass through the tank and have a sleeve end and a pointed end, at least one of these two ends projecting beyond the remaining dimensions of the actual drainage tank. In this way, two identical drainage tanks can be coupled in that the two pipes of these two tanks are connected to one another in a manner known per se with socket ends and spigot ends, so that overall the two pipes form a longer overall pipe. The whole made up of several individual tanks

Tank bzw. eine daraus gebildete Rigole wird demzufolge vollständig von dem Rohr durchsetzt, so dass Sedimente, wenn sie stirnseitig aus dem Rohr eines Tanks gelangen, nicht in den restlichen Tank gelangen können, sondern vielmehr in das an- schließende Rohr des benachbarten Tanks.The tank or a trench formed from it is therefore completely penetrated by the pipe, so that sediments, when they come out of the front of the pipe of a tank, cannot get into the rest of the tank, but rather into the connecting pipe of the neighboring tank.

Innerhalb einer Rigole, die aus einer Vielzahl von Drainage- Tanks besteht, müssen lediglich wenige Drainage-Tanks mit dem beschriebenen Sedimentrohr ausgestaltet sein, nämlich nur die Drainage-Tanks, die sich an den Wassereinlass anschließen, so dass das Sedimentrohr von diesem Wassereinlass aus- gehend die Länge bzw. Breite der Rigole durchsetzt und am anderen Ende beispielsweise an einen Spülschacht anschließt.Within a trench, which consists of a large number of drainage tanks, only a few drainage tanks need to be equipped with the sediment pipe described, namely only the drainage tanks that connect to the water inlet, so that the sediment pipe extends from this water inlet. going through the length or width of the trench and at the other end, for example, connected to a flushing shaft.

Da bei den erfindungsgemäßen Drainage-Tanks beide Enden des Tanks durchbrochen sind, da sich das Sedimentrohr durch den Tank hindurch erstreckt, kann eine ausreichende Druckstabilität, beispielsweise um eine Überfahrbarkeit des Drainage- Tanks zu gewährleisten, durch zusätzlich im Tankinneren vorgesehene Stützwände sichergestellt werden, wobei wenigstens ei- ne derartige Stützwand vorgesehen ist. Die Druckstabilität sichert die mechanische Beständigkeit des Tanks, dass Beschä- gigungen seiner Wände, die zu einem unerwünschten Eindringen von Erdreich und somit von unkontrolliert eindringenden Sedimenten führen könnten, verhindert werden.Since both ends of the tank are broken through in the drainage tanks according to the invention, since the sediment pipe extends through the tank, sufficient pressure stability, for example to ensure that the drainage tank can be driven over, can be ensured by additional walls provided in the interior of the tank, whereby at least one such support wall is provided. The pressure stability ensures the mechanical stability of the tank, preventing the walls from being damaged, which could lead to undesired penetration of soil and thus uncontrolled penetration of sediments.

Vorteilhaft kann vorgesehen sein, dass eine derartige Stützwand innerhalb des Drainage-Tanks dort vorgesehen ist, wo sich der Außendurchmesser des Drainagerohrs ändert, nämlich im Übergang vom Muffenbereich zum übrigen Rohrdurchmesser. Die erwähnte Stützwand im Inneren des Drainage-Tanks kann daher einen Anschlag für das Muffenende des Rohres schaffen. Dadurch ist erstens die Montage des Rohrs einfach und zweitens ergibt sich eine stets korrekte und gleichartige Ausrichtung der Rohre. Diese gleichartige Ausrichtung der Rohre stellt bei der Verbindung von mehreren Drainage-Tanks eine zuverlässigeIt can advantageously be provided that such a support wall is provided within the drainage tank where the outside diameter of the drainage pipe changes, namely in the transition from the socket area to the remaining pipe diameter. The mentioned support wall inside the drainage tank can therefore create a stop for the socket end of the pipe. Firstly, this makes assembly of the tube simple, and secondly, the tubes are always correctly and uniformly aligned. This similar orientation of the pipes is a reliable one when connecting several drainage tanks

Dichtheit des aus einzelnen Rohren gebildeten Gesamtrohres sicher und gewährleistet somit, dass Sedimente nicht ungewollt an den Verbindungsstellen der einzelnen Rohre austreten und in die das Rohr umgebenden Bereiche des Tanks gelangen kön- nen.Tightness of the entire pipe formed from individual pipes is guaranteed and thus ensures that sediments do not escape unintentionally at the connection points of the individual pipes and can reach the areas of the tank surrounding the pipe.

Ein Ausführungsbeispiel der Erfindung wird anhand der schematischen Zeichnungen nachfolgend näher erläutert. Dabei zeigtAn embodiment of the invention is explained in more detail below with reference to the schematic drawings. It shows

In Fig. 1 ist mit 1 insgesamt ein Drainage-Tank bezeichnet. Dieser weist zwei Stirnwandungen 2 und 3 sowie Seitenwandungen 4, eine Bodenwandung sowie eine Deckelwandung 5 auf. Die Deckelwandung 5 ist in Fig. 1 abgenommen und es ist ersichtlich, dass der Drainage-Tank 1 von einem Rohr 6 durchsetzt ist. Das Rohr 6 weist ein über den Drainage-Tank 1 hinausragendesIn Fig. 1, 1 designates a drainage tank. This has two end walls 2 and 3 and side walls 4, a bottom wall and a cover wall 5. The cover wall 5 is removed in FIG. 1 and it can be seen that the drainage tank 1 is penetrated by a tube 6. The tube 6 has a protruding beyond the drainage tank 1

Spitzende 7 auf sowie ein gegenüberliegendes Muffenende 8. Im oberen Abschnitt der Rohrwandung ist eine Vielzahl von Durchtrittsöffnungen 9 vorgesehen, während ein unterer Abschnitt 10 der Rohrwandung wannenartig geschlossen ist.Pointed end 7 on and an opposite sleeve end 8. In the upper section of the pipe wall, a plurality of through openings 9 is provided, while a lower section 10 of the pipe wall is closed like a trough.

Weiterhin ist aus Fig. 1 ersichtlich, dass innerhalb des Drainage- Tanks 1 eine Vielzahl von Stützwänden 11 vorgesehen ist.Furthermore, it can be seen from FIG. 1 that a multiplicity of supporting walls 11 are provided within the drainage tank 1.

Fig. 2 zeigt einen Blick auf die Stirnwandung 2 des Drainage- Tanks 1 , welche das Muffenende 8 des Rohres 6 aufnimmt. DieFig. 2 shows a view of the end wall 2 of the drainage tank 1, which receives the sleeve end 8 of the pipe 6. The

Öffnung in dieser Stirnwandung 2 ist größer als die in der gegenüberliegenden Stirnwandung 3, da das Rohr 6 im Bereich seines Muffenendes 8 einen größeren Durchmesser aufweist als in seinem übrigen Verlauf.Opening in this end wall 2 is larger than that in the opposite end wall 3, since the tube 6 has a larger diameter in the area of its sleeve end 8 than in its rest.

Fig. 3 zeigt, dass die der Stirnwandung 2 benachbarte Stützwand 11 einen Anschlag für das Muffenende 8 des Rohres 6 bildet, so dass es produktionstechnisch einfach ist, zunächst den Drainage-Tank 1 aus seinen verschiedenen Wandungen zu erstellen, anschließend die Wandungen zu durchbohren und dasFig. 3 shows that the end wall 2 adjacent support wall 11 forms a stop for the sleeve end 8 of the tube 6, so that it is technically simple to first create the drainage tank 1 from its various walls, then to drill through the walls and the

Rohr 6 einzusetzen, wobei es automatisch mit seinem Muffe- nende bis an die in Fig. 2 dargestellte Stützwand 11 geführt wird, so dass sich dementsprechend ein definierter Überstand des Rohr-Spitzendes über die Stirnwandung 3 ergibt.Insert pipe 6, whereby it automatically with its sleeve 2 to the support wall 11 shown in FIG. 2, so that there is accordingly a defined projection of the pipe tip end over the end wall 3.

Fig. 4 zeigt zwei gleichartige Drainage-Tanks 1 , wobei das Spitzende 7 des linken Drainage-Tanks 1 übersteht und in das Muffenende des Rohres des rechts dargestellten Drainage-Tanks 1 eingeführt werden kann.FIG. 4 shows two similar drainage tanks 1, the tip end 7 of the left drainage tank 1 protruding and can be inserted into the socket end of the pipe of the drainage tank 1 shown on the right.

Fig. 5 zeigt die beiden Drainage-Tanks 1 von Fig. 4 in montiertem Zustand, wobei hier das über die Stirnwandung 3 des rechten Tanks 1 ragende Stirnende 7 des zugehörigen Rohres 6 ersichtlich ist.FIG. 5 shows the two drainage tanks 1 of FIG. 4 in the assembled state, the front end 7 of the associated pipe 6 projecting over the end wall 3 of the right tank 1 being shown here.

Die dargestellten Drainage-Tanks 1 können Teil einer insgesamt erheblich größeren Rigole sein, wobei in einem derartigen Fall eine Vielzahl ähnlicher, jedoch rohrfreier Drainage-Tanks Verwendung findet, die insgesamt mit einer wasserpermeabelen Umhüllung versehen werden, um Wasser zunächst aufzuneh- men und anschließend an das umgebende Erdreich wieder abzugeben.The drainage tanks 1 shown can be part of a substantially larger drainage system, in which case a large number of similar, but pipe-free drainage tanks are used, which are all provided with a water-permeable coating in order to absorb water first and then on to give up the surrounding soil again.

Wenn Sedimente, die sich in den Rohren 6 abgelagert haben, ausgespült werden sollen, so kann entweder mittels einer Spül- düse oder durch einfache Einleitung von Spülflüssigkeit eineIf sediments that have been deposited in the tubes 6 are to be rinsed out, either by means of a rinsing nozzle or by simply introducing rinsing liquid

Durchströmung der Rohre 6 bewirkt werden. Zu diesem Zweck können die Rohre an ihrem Ende an einen Spülschacht anschließen, in welchem das Sediment gesammelt wird und aus dem es auf eine an sich bekannte Weise abgezogen, beispiels- weise abgesaugt werden kann.Flow through the tubes 6 are effected. For this purpose, the pipes can be connected at their end to a rinsing shaft, in which the sediment is collected and from which it can be drawn off, for example sucked off, in a manner known per se.

Vor der Rigole ist vorzugsweise ein Filter vorgesehen, so dass die Sedimentablagerung innerhalb der Rigole möglichst begrenzt wird und lediglich in entsprechend großen Zeiträumen eine Durchspülung der Rigole und insbesondere der Rohre 6 erforderlich ist. A filter is preferably provided in front of the trench, so that sediment deposition within the trench is limited as much as possible and flushing of the trench and in particular the pipes 6 is only necessary in correspondingly long periods of time.
