Description

Die Erfindung betrifft eine Versickerungseinrichtung Versickerung von Wasser, insbesondere RegenwasserThe invention relates to a percolation device infiltration of water, especially rainwater

Es sind Versickerungseinrichtungen bekannt, die in der Regel dazu eingesetzt werden, Regenwasser in den Erdboden einzuleiten, ohne dass es dabei an der Oberfläche zu einem Rückstau kommt, d.h. ohne dass überschwemmungsartige Zuständige auftreten. Auch ohne Kanalisation soll es ermöglicht werden, Regenwasser in den Erdboden einzuleiten. Ferner soll das Regenwasser nicht in eine Kanalisation eingeleitet werden, da auch die Einleitung von Regenwasser, beispielsweise von großflächigen Parkplätzen, großflächigen Dächern oder dgl. mit Gebühren seitens der Städte und Kommunen belegt wird. Um Kosten einzusparen, werden dementsprechend Versickerungseinrichtungen verwendet, um Regenwasser in den Boden einzuleiten.There are known infiltration devices, which are usually used to initiate rainwater into the ground, without it comes to the surface to a backwater, ie without flooding-like responsible occur. Even without drains, it should be possible to initiate rainwater into the ground. Furthermore, the rainwater should not be discharged into a sewage system, as well as the introduction of rainwater, for example, large parking lots, large roofs or the like. With fees from the cities and municipalities is occupied. In order to save costs, infiltration devices are accordingly used to introduce rainwater into the soil.

Dabei wird das Regenwasser über eine Zulauföffnung in den Schachtabschnitt einer Versickerungseinrichtung bzw. eines Versickerungsschachtes eingeleitet und dann über eine Ablauföffnung in ein Sickerrohr befördert werden kann. Das Sickerrohr ist an seinem Außenumfang mit einer Vielzahl von Löchern bzw. Perforationen versehen, über die das Wasser in den Boden eingeleitet werden kann. Die Sickerrohre sind dabei häufig in ein Kiesbett eingelegt, so dass ausgehend von den Öffnungen in dem Sickerrohr das Wasser in das Kiesbett und anschließend in den umgebenden Erdboden eingeleitet werden kann, ohne dass es selbst bei größeren Wassermengen, die bei sintflutartigen Regenfällen anfallen können, zu Rückstaus kommen kann.The rainwater is introduced via an inlet opening in the shaft section of a percolation device or a percolation shaft and then can be transported via a drain opening in a seepage pipe. The seepage pipe is provided at its outer periphery with a plurality of holes or perforations through which the water can be introduced into the soil. The seepage pipes are often placed in a gravel bed, so that starting from the openings in the seepage pipe, the water can be introduced into the gravel bed and then into the surrounding soil, without it even with larger amounts of water, which may be incurred in torrential rains Backlog can come.

Bei derartigen Versickerungseinrichtungen hat es sich nun gezeigt, dass durch Staubpartikel, Schmutzablagereungen oder dgl., die auf Dachflächen, Parkplatzflächen oder dgl. anfallen können, auch zu Schmutzablagerungen in den Schächten und Versickerungsrohren kommen kann. Die Versickerungsrohre, d.h. deren Perforationen oder Öffnungen sowie das diesen zugeordnete Kiesbett kann nun durch derartige Schmutzanteile im Regenwasser im Laufe der Zeit zugesetzt werden, bzw. lässt die Ableitungskapazität eines verschlammten Sickerrohres bzw. eines verschlammten Kiesbettes nach und selbst bei schwachen Regenfällen kann das in die Versickerungseinrichtung eingeleitete Regenwasser nicht mehr sachgerecht in den Untergrund eingeleitet werden.With such infiltration devices, it has now been found that dust particles, dirt deposits or the like, which may be incurred on roof surfaces, parking areas or the like, can also lead to dirt deposits in the shafts and infiltration pipes. The infiltration pipes, i. their perforations or openings and the associated gravel bed can now be added by such amounts of dirt in the rainwater over time, or can the discharge capacity of a silted drainage pipe or a muddy gravel bed and even in weak rainfall, the rainwater introduced into the infiltration device not more properly be launched into the underground.

Eine derartige, durchaus als problematisch anzusehende Versickerungseinrichtung ist beispielsweise aus dem DE 296 16 503.4 U1 bekanntSuch, to be regarded as problematic infiltration device is for example from the DE 296 16 503.4 U1 known

Die DE 197 01 522 C1 offenbart eine Versickerungseinrichtung , bei welcher eine Filtereinrichtung an einem radialen Innenflansch eines oberen Schachtunterabschnitts eingehängt ist und der obere Schachtunterabschnitt mit seinem Innenflansch auf einer Adapterplatte aufsitzt, die ihrerseits in einer an einem oberen Randabschnitt eines unteren Schachtunterabschnitts ausgebildeten Ringschulter aufliegt. DE 197 01 522C1 wird als nächstliegender stand der Technik augesehen.The DE 197 01 522 C1 discloses a percolation device in which a filter device is suspended from a radial inner flange of an upper manhole subsection and the upper manhole subsection is seated with its inner flange on an adapter plate, which in turn rests in an annular shoulder formed on an upper edge section of a lower manhole subsection. DE 197 01 522C1 will be the closest thing to the technology.

Zur weiteren Illustration des technischen Hintergrunds kann auf die Druckschriften US 5,810,510 A , US 5,511,904 A sowie DE 196 33 987 A verwiesen werden, welche jeweils eine Versickerungseinrichtung zur Versickerung von Wasser mit einem Schachtabschnitt offenbaren, wobei wenigstens eine Zulauföffnung am Schachtabschnitt und wenigstens eine Ablauföffnung am Schachtabschnitt vorgesehenen sind.For further illustration of the technical background may refer to the publications US 5,810,510 A . US 5,511,904 A such as DE 196 33 987 A are each refer to a percolation device for infiltration of water with a manhole section, wherein at least one inlet opening at the manhole section and at least one drain opening are provided at the manhole section.

Dabei sind folgende Merkmale des Anspruchs 1 in Dokument US5511904 offenbart: eine Versickerungseinrichtung zur Versickerung von Wasser, insbesondere Regenwasser, mit einem Schachtabschnitt, mit wenigstens einer Zulauföffnung am Schachtabschnitt und mit wenigstens einer Ablauföffnung am Schachtabschnitt, wobei im Schachtabschnitt zwischen der Zulauföffnung und der Ablauföffnung eine Filtereinrichtung reversibel angeordnet ist (Fig.1, Bezugszeichen 20), wobei im Schachtabschnitt zwischen der Zulauföffnung und der Ablauföffnung eine Halteeinrichtung angeordnet ist (Fig.1, Bezugszeichen 40, 42), die die Filtereinrichtung hält (Fig.1, Bezugszeichen 20, 42), und wobei der Schachtabschnitt in zwei Schachtunterabschnitte unterteilt ist (Fig.1, Bezugszeichen 2, 46), wobei der eine Schachtunterabschnitt die wenigstens eine oder mehrere Zulauföffnungen aufweist, wobei die beiden Schachtunterabschnitte zueinander um die gemeinsame Längsachse drehbar sind (siehe Fig.1; Spalte 3, Zeilen 9-15, 27-32).The following features of claim 1 in document US5511904 discloses a percolation device for infiltration of water, in particular rainwater, with a shaft section, with at least one inlet opening at the shaft section and with at least one outlet opening at the shaft section, wherein a filter device is arranged reversibly in the shaft section between the inlet opening and the outlet opening ( Fig.1 , Reference numeral 20), wherein a holding device is arranged in the shaft section between the inlet opening and the outlet opening ( Fig.1 , Reference numeral 40, 42) holding the filter device ( Fig.1 , Reference numerals 20, 42), and wherein the manhole section is divided into two manhole sub-sections ( Fig.1 Reference numeral 2, 46), wherein the one shaft sub-section has the at least one or more inlet openings, wherein the two shaft subsections are mutually rotatable about the common longitudinal axis (see Fig.1 ; Column 3, lines 9-15, 27-32).

Ferner offenbart das Dokument US5511904 , dass die Halteeinrichtung an der inneren Seite der Wandung der oberen Schachtunterabschnitte angeordnet wird (und nicht, wie im Anspruch 1 beansprucht, auf dem Ansatzabschnitt; siehe Fig.1, Bezugszeichen 40; Spalte 3, Zeilen 9-12); und dass die unterste Seite dieser Schachtunterabschnitte einen Ansatzabschnitt aufweist, der sich in den anderen Schachtunterabschnitt erstreckt (Spalte 3, Zeilen 12-15), und wobei der andere Schachtunterabschnitt um den Ansatzabschnitt drehbar ist, bevor die beide Schachtunterabschnitt durch Schrauben befestigt werden, damit ihre relative Drehung verhindert wird (siehe Figuren 1 und 2, die Schrauben (Bezugszeichen 38 und 64; siehe Spalte 3, Zeilen 8-15; 27-31).Further, the document discloses US5511904 in that the holding device is arranged on the inner side of the wall of the upper manhole subsections (and not on the neck section as claimed in claim 1; Fig.1 , Reference numeral 40; Column 3, lines 9-12); and that the lowermost side of said tray subsections has a lug portion extending into the other tray subsection (col. 3, lines 12-15), and wherein the other tray subsection is rotatable about the lug portion before the two tray subsections are fastened by screws so that their relative rotation is prevented (see FIGS. 1 and 2 , the screws (reference numerals 38 and 64, see column 3, lines 8-15, 27-31).

Aufgabe der Erfindung ist es, die aus dem Stand der Technik bekannten Versickerungseinrichtungen derart weiterzubilden, dass sie leichter und flexibler zu montieren sind und kostengünstig herstellbar sind.The object of the invention is to develop the known from the prior art infiltration devices such that they are easier and more flexible to assemble and are inexpensive to produce.

Gemäß der Erfindung wird diese Aufgabe durch Versickerungseinrichtung nach Anspruch 1 gelöst.According to the invention, this object is achieved by infiltration device according to claim 1.

Zweckmäßige Ausführungsformen der erfindungsgemäßen Einrichtung werden durch die Unteransprüche definiert.Advantageous embodiments of the device according to the invention are defined by the subclaims.

Die gemäß der Erfindung zu erzielenden Vorteile beruhen darauf, dass im Schachtabschnitt zwischen der Zulauföffnung und der Ablauföffnung eine Filtereinrichtung reversibel anordenbar ist. D.h., die Filtereinrichtung kann, je nach Bedarf, aus dem Versickerungsschacht bzw. aus der Versickerungseinrichtung herausgezogen werden, um Schmutz, der von der Filtereinrichtung aufgefangen worden ist, zu entfernen. Dieser Schmutz kann auf diese Weise nicht mehr in das perforierte bzw. gelochte oder geschlitzte Sickerrohr, das in der Regel in einem Kiesbett horizontal im Erdboden verläuft, gelangen und dieses blockieren.The advantages to be achieved according to the invention are based on the fact that a filter device can be reversibly arranged in the shaft section between the inlet opening and the outlet opening. That is, the filter device may be withdrawn from the infiltration well or percolation device as needed to remove debris collected by the filter device. This dirt can not get in this way in the perforated or perforated or slotted seepage pipe, which usually runs horizontally in a gravel bed in the ground, and block this.

In vorteilhafter Weise ist in dem Schachtabschnitt zwischen der Zulauföffnung und der Ablauföffnung eine Halteeinrichtung angeordnet, die die Filtereinrichtung hält, und insbesondere reversibel hält. Dabei kann die Halteeinrichtung über den Schachtumfang an der Innenseite des Schachtes angeordnet sein, beispielsweise in der Gestalt von Schrauben oder Bolzen, die in das Schachtinnere radial hineinragen. Natürlich kann die Halteeinrichtung auch ansonsten in irgendeiner Weise realisiert sein, beispielsweise als Schulterabschnitt, der über Abschnitte am Innenumfang durchgehend vorgesehen ist oder sich insgesamt über den gesamten Innenumfang bevorzugt in einer Ebene senkrecht zu der vertikalen Mittelachse des Schachtabschnittes erstrecken kann.Advantageously, a holding device is arranged in the shaft section between the inlet opening and the outlet opening, which holds the filter device, and in particular reversibly holds. In this case, the holding device can be arranged over the shaft circumference on the inside of the shaft, for example in the form of screws or bolts which project radially into the shaft interior. Of course, the holding device may otherwise be realized in any other way, for example as a shoulder portion, which is continuously provided over portions on the inner circumference or may extend over the entire inner circumference preferably in a plane perpendicular to the vertical center axis of the manhole section.

Als Halteeinrichtung kann auch eine Wellung am Innenumfang des Schachtabschnittes eingesetzt werden, beispielsweise wenn der Schachtabschnitt als Wellrohr ausgebildet ist. In dem Falle, dass der Schachtabschnitt als Wellrohr mit glatter Innenhaut ausgebildet ist, kann beispielsweise das glatte Innenrohr an einer Stelle weggelassen werden, so dass die . Filtereinrichtung bzw. die Halteeinrichtung in eine Wellung am Innenumfang des Schachtabschnittes einzugreifen vermag.As a holding device, a corrugation can be used on the inner circumference of the shaft section, for example, when the shaft section is formed as a corrugated pipe. In the event that the shaft section is formed as a corrugated tube with a smooth inner skin, for example, the smooth inner tube can be omitted at one point, so that the. Filter device or the holding device is able to engage in a corrugation on the inner circumference of the shaft section.

Die Halteeinrichtung kann auch beispielsweise als ein Innenrohr ausgebildet sein, das in den Schachtabschnitt eingesetzt wird und beispielsweise auf dem Schachtboden aufsteht. Dieses Innenrohr kann dann entsprechende Durchlassöffnungen bzw. Durchlassschlitze haben, um das Wasser ausgehend von der Filtereinrichtung zu der Ablauföffnung des Schachtabschnittes durchzulassen. Natürlich kann die Halteeinrichtung auch in der Form eines Haltekörpers oder dgl. ausgebildet sein, beispielsweise stativartig oder dgl., wobei die Stativbeine z.B. ebenfalls unten auf dem Schachtboden des Schachtabschnitts der Versickerungseinrichtung gemäß der Erfindung aufstehen können. Die Filtereinrichtung würde hier in das obere Ende des Innenrohres bzw. den Stativring eingehängt werden.The holding device can also be designed, for example, as an inner tube, which is inserted into the shaft section and, for example, stands up on the shaft bottom. This inner tube may then have respective passage openings or passage slots in order to pass the water from the filter device to the drain opening of the shaft section. Of course, the holding device may also be in the form of a holding body or the like., For example, like a tripod or the like., Wherein Tripod legs, for example, also down on the shaft bottom of the shaft portion of the infiltration device according to the invention can get up. The filter device would be suspended here in the upper end of the inner tube or the tripod ring.

Eine vorteilhafte Ausführungsform gemäß der Erfindung ergibt sich, wenn der Schachtabschnitt in zwei Unterabschnitte unterteilt ist. Dabei weist der eine Schachtunterabschnitt die Zulauföffnung auf, während dem anderen der Schachtunterabschnitte die Ablauföffnung zugeordnet ist. Die beiden Schachtabschnitte sind dabei zueinander um die gemeinsame Längsachse drehbar, so dass der Anschluss eine Zulaufrohres und eines Ablaufrohres einfacher gestaltet werden kann, indem die Anschlussstutzen an der Zulauföffnung und der Ablauföffnung der erfindungsgemäßen Versickerungseinrichtung praktisch zu den anzuschließenden Rohren durch Drehen der Schachtunterabschnitte um deren gemeinsame Längsachse ausgerichtet werden können.An advantageous embodiment according to the invention results when the manhole section is divided into two subsections. In this case, one of the shaft subsection has the inlet opening, while the other of the shaft subsections is assigned to the outlet opening. The two shaft sections are rotatable relative to each other about the common longitudinal axis, so that the connection of an inlet pipe and a drain pipe can be made simpler by the connecting pieces at the inlet opening and the drain opening of the infiltration device according to the invention practically to the pipes to be connected by rotating the shaft subsections to their common Longitudinal axis can be aligned.

Einer der Schachtunterabschnitte weist einen Ansatzabschnitt auf , der insbesondere in etwa wie ein Ring ausgestaltet ist. Dieser Ringabschnitt kann in den anderen Schachtunterabschnitt erstreckt werden, wobei der andere Schachtunterabschnitt um den Ansatzabschnitt drehbar ist. Durch den Ansatzabschnitt, beispielsweise einen ringartigen Abschnitt, werden die beiden Schachtunterabschnitte um die gemeinsame Längsachse drehbar miteinander verbunden bzw. zusammengesteckt. Durch die Fügestelle kann anschließend keine Erdreich mehr im eingebauten Zustand eindringen. Um eine Fixierung der beiden Schachtunterabschnitte zueinander vorzunehmen, kann beispielsweise eine Manschette, ein Spannring oder ein vergleichbarer Gegenstand zum Einsatz gelangen.One of the shaft subsections has a neck portion, which is designed in particular approximately like a ring. This ring portion may be extended into the other tray sub-portion, the other tray sub-portion being rotatable about the nose portion. By the neck portion, for example, a ring-like portion, the two shaft sub-sections are rotatably connected or plugged together about the common longitudinal axis. The joint can then no more soil in the installed state penetrate. In order to make a fixation of the two shaft subsections to each other, for example, a sleeve, a clamping ring or a comparable object can be used.

In diesem Falle, wenn die Halteeinrichtung als Schulterabschnitt in den Schachtabschnitt hineinragt, kann die Filtereinrichtung mit einem entsprechend geringeren äußeren Durchmesser ausgebildet sein und an ihrem Außenumfang mit einem Auflageabschnitt ausgebildet sein, um auf dem Schulterabschnitt aufzuliegen. Da die Filtereinrichtung dann einen dementsprechend geringeren Außendurchmesser aufweist als die lichte Weite des Schachtabschnittes, ist es einfach, die reversible Filtereinrichtung von einem oberen Endabschnitt der Versickerungseinrichtung aus zu Leerungs- und Reinigungszwecken herauszuziehen und wieder nach deren Regeneration in die Versickerungseinrichtung einzusetzen.The holding device may preferably be formed as a shoulder portion which extends over one or more parts of the inner circumference of the shaft section or the holding device. In this case, when the holding device as a shoulder portion in the Slot section protrudes, the filter device may be formed with a correspondingly smaller outer diameter and be formed on its outer periphery with a support portion to rest on the shoulder portion. Since the filter device then has a correspondingly smaller outer diameter than the inside diameter of the shaft section, it is easy to extract the reversible filter device from an upper end section of the infiltration device for emptying and cleaning purposes and to insert it into the infiltration device again after its regeneration.

Die Filtereinrichtung weist bevorzugt einen Stabilisierungs- bzw. Grobfilterabschnitt auf, der grobe Festbestandteile im Wasser zurückhalten kann. Der Stabilisierungsabschnitt kann dabei eimerförmig ausgebildet sein und Löcher aufweisen, so dass nur Steine, Lehmbrocken, Blätter und dgl. zurückgehalten werden, während das Wasser mit feineren Schwebteilen, Sand, Schlamm und dgl. durch die großen Öffnungen des Stabilisierungsabschnittes hindurch kann.The filter device preferably has a stabilizing or coarse filter section, which can retain coarse solid constituents in the water. The stabilizing portion may be formed bucket-shaped and have holes, so that only stones, loams, leaves and the like. Retained, while the water with finer suspended parts, sand, mud and the like. Through the large openings of the stabilization section can pass.

In den Fig. sind gleiche oder wenigstens funktionsgleiche Bestandteile durch die gleichen Bezugszeichen gekennzeichnet, so dass sich Wiederholungen erübrigen.In the figures, identical or at least functionally identical components are identified by the same reference numerals, so that repetitions are unnecessary.

Die Ausführungsform gemäß Fig. 1 lässt eine Versickerungseinrichtung bzw. einen Versickerungsschacht 10 mit Merkmalen gemäß der Erfindung erkennen.The embodiment according to Fig. 1 discloses a percolation device or infiltration well 10 having features according to the invention.

Der Versickerungsschacht 10 weist einen oberen Schachtunterabschnitt 12 und einen unteren Schachtunterabschnitt 14 auf. Am oberen Ende des Schachtunterabschnittes 12 ist eine Wartungsöffnung 22 vorgesehen. Am unteren Ende des unteren Schachtunterabschnittes 14 ist ein Schachtboden 20 angeordnet.The infiltration well 10 has an upper well subsection 12 and a lower well subsection 14. At the upper end of the shaft subsection 12, a maintenance opening 22 is provided. At the lower end of the lower shaft subsection 14, a shaft bottom 20 is arranged.

Der obere Schachtunterabschnitt 12 weist eine Zulauföffnung 16 bzw. einen entsprechenden Anschlussstutzen 16 auf, an den ein Zulaufrohr 50 angeschlossen ist. Das Zulaufrohr 50 kann beispielsweise Wasser von dem Fallrohr einer Dachrinne zuführen bzw. beispielsweise Wasser von einer Ablaufrinne eines Autoparkplatzes oder dgl.The upper shaft sub-section 12 has an inlet opening 16 or a corresponding connecting piece 16, to which an inlet pipe 50 is connected. The inlet pipe 50 may for example supply water from the downpipe of a gutter or, for example, water from a gutter of a car park or the like.

Der untere Schachtunterabschnitt 14 weist eine Ablauföffnung bzw. einen Stutzen zum Anschluss eines Rohres 18 auf. An diesen Stutzen 18 wird ein Rohr 52 angeschlossen, das als Versickerungsrohr in den Untergrund, d.h. ins Erdreich eingebettet wird. Das Versickerungsrohr 52 ist mit Perforationen bzw. Schlitzen oder Löchern versehen und wird in der Regel in ein Kiesbett eingebettet, damit das Wasser, das in die Versickerungseinrichtung 10 eingeleitet wird über die Öffnungen und das Kiesbett in den Untergrund eingeleitet werden kann.The lower shaft subsection 14 has a drain opening or a connection for connecting a pipe 18. At this port 18, a pipe 52 is connected, the as infiltration pipe into the ground, ie embedded in the soil. The infiltration tube 52 is provided with perforations or holes and is usually embedded in a gravel bed so that the water introduced into the infiltration device 10 can be introduced into the underground via the openings and the gravel bed.

Das Rohr des Schachtabschnittes 12, 14 kann ein Wellrohr, ein Glattrohr, oder wie hier ein Wellrohr mit Wellungen 12a und einem glatten Innenrohr 12b sein. Wellrohre halten natürlich einen größeren Erddruck aus und sind generell stabiler als glattwandige Rohre. Die Kombination aus einer gewellten Wandung und einer inneren glatten Wandung ist ideal, da in vertikaler Richtung keine Abmessungsvariationen zu befürchten sind und gleichzeitig der Erddruck über die Wellungen besser abgefangen werden kann.The tube of the shaft section 12, 14 may be a corrugated tube, a smooth tube, or as here a corrugated tube with corrugations 12a and a smooth inner tube 12b. Of course corrugated pipes keep a larger earth pressure and are generally more stable than smooth-walled pipes. The combination of a corrugated wall and an inner smooth wall is ideal, as in the vertical direction no dimensional variations are to be feared and at the same time the earth pressure can be better absorbed via the corrugations.

An dem unteren Ende des oberen Schachtunterabschnitts 12 ist eine Halteeinrichtung 30 in der Form eines radial nach innen erstreckten Ringes zu erkennen. Dieser weist einen Ansatzabschnitt 32 auf, der in den oberen Endabschnitt des unteren Schachtunterabschnittes 14 eingesteckt werden kann. Am oberen Ende ist die Halteeinrichtung 30 an dem oberen Schachtunterabschnitt 12 festgelegt, beispielsweise festgeklebt, mit diesem durch Kunststoffschweißung verbunden oder dgl.At the lower end of the upper manhole sub-section 12, a holding device 30 in the form of a radially inwardly extending ring can be seen. This has a neck portion 32 which can be inserted into the upper end portion of the lower manhole subsection 14. At the upper end of the holding device 30 is fixed to the upper shaft sub-section 12, for example, glued, connected to this by plastic welding or the like.

Eine Filtereinrichtung 34 bis 42 ist an dem unteren Abschnitt des oberen Schachtunterabschnittes 12 in die Halteeinrichtung 30 eingehängt. Wenn der obere Schachtunterabschnitt abgesenkt wird (siehe die Pfeile) verschwindet die Filtereinrichtung vollends in dem unteren Schachtunterabschnitt 14.A filter device 34 to 42 is suspended on the lower portion of the upper shaft subsection 12 in the holding device 30. When the upper manhole subsection is lowered (see the arrows), the filter device completely disappears in the lower manhole subsection 14.

Die Filtereinrichtung umfasst einen Stützkörper bzw. einen Grobfilter 36 und einen Feinfilter 40. Der Grobfilter bzw. Stützkörper 36 weist Durchlassöffnungen auf, durch die das in die Einrichtung 10 eingeleitete Wasser in den Feinfilter 40 einströmen kann.The filter device comprises a support body or a coarse filter 36 and a fine filter 40.

Ein trichterartiger Bereich 34 kann an dem Grobfilter vorgesehen werden, um für den Feinfilter den nötigen Freiraum zu schaffen, um, ohne mit der Halteeinrichtung 30 zu verhaken, aus seiner Halterung nach oben durch die Öffnung 22 des oberen Schachtunterabschnittes 12 entfernt und durch diese wieder nach einer Entleerung bzw. Reinigung in die erfindungsgemäße Versickerungseinrichtung 10 eingesetzt werden zu können.The support body or coarse filter has a shoulder portion 38 which comes to rest on the shoulder region of the holding device 30. A funnel-like region 34 may be provided on the coarse filter to provide the necessary clearance for the fine filter, to, without catching with the holding device 30, to be removed from its holder upwards through the opening 22 of the upper shaft subsection 12 and to be able to be inserted through this again after emptying or cleaning in the infiltration device 10 according to the invention.

Der Stützkörper bzw. Grobfilter 36 kann beispielsweise als Kunststoffeimer mit Löchern oder als geschlitzter Metalleimer ausgebildet sein. Er kann auch käfigartig ausgebildet sein. Jedenfalls sollte der Grobfilter bzw. Stützkörper 36 dazu in der Lage sein, für den Feinfilter als Halterung zu dienen und grobe Bestandteile zurückzuhalten.The support body or coarse filter 36 may be formed, for example, as a plastic bucket with holes or slotted metal buckets. He may also be formed like a cage. In any case, the coarse filter or supporting body 36 should be able to serve as a holder for the fine filter and to retain coarse constituents.

Natürlich ist es prinzipiell auch möglich, lediglich einen Feinfilter 40 mit einem Flanschabschnitt in die Halterung 30 einzusetzen.Of course, it is also possible in principle to use only a fine filter 40 with a flange portion in the holder 30.

Bei der vorliegenden Ausführungsform weist der Feinfilter 40 einen Bund 42 auf, der den oberen Auflageabschntt 38 des Grobfilters bzw. Stützkörpers 36 sich radial einwärts verjüngend umgibt. Dieser Bund kann mittels einer Schnur oder dgl. geweitet oder verengt werden, um zu Reinigungszwecken entfernt zu werden bzw. zu Filterzwecken wieder angeordnet zu werden.In the present embodiment, the fine filter 40 has a collar 42, which surrounds the upper Auflageabschntt 38 of the coarse filter or supporting body 36 radially inwardly tapered. This collar can be expanded or narrowed by means of a string or the like, to be removed for cleaning purposes or to be arranged for filtering purposes again.

In Fig. 2 ist eine Halterung 30 mit einem angedeuteten Grobfilter bzw. Stützkörper 36 dargestellt. Die Halteeinrichtung 30 weist einen Schulterabschnitt auf, der ebenfalls durch das Bezugszeichen 30 gekennzeichnet ist. Der Schulterabschnitt ist dabei in einzelne Segmente unterteilt, kann natürlich aber auch durchgehend ausgebildet sein. Der Ansatzabschnitt 32 ist außen an dem Schulterabschnitt 30 zu erkennen. Befestigungsabschnitte 33 können herangezogen werden, um die Halteeinrichtung bzw. den Drehring 30, 32 an einem der Schachtunterabschnitte 12, 14 festzulegen.In Fig. 2 a holder 30 is shown with an indicated coarse filter or support body 36. The holding device 30 has a shoulder portion, which is also identified by the reference numeral 30. The shoulder portion is divided into individual segments, but of course can also be formed continuously. The neck portion 32 can be seen on the outside of the shoulder portion 30. Attachment sections 33 can be used to fix the holding device or the rotary ring 30, 32 at one of the shaft subsections 12, 14.

Gemäß Fig. 2a ist ein oberer Bereich 32 a, der ebenfalls ringartig ausgebildet ist, zu erkennen. Dieser kann in die untere Öffnung des oberen Schachtunterabschnittes 12 eingesetzt werden, um mit dem oberen Schachtunterabschnitt 12 verbunden zu werden. Dies kann, wie oben angedeutet, durch Verkleben, Reibschweißen, usw., durchgeführt werden. Zur Stabilisierung des Schulterabschnittes 30 können Stabilisierungsstege 31 vorgesehen sein, die den Schulterabschnitt 30 belastbarer machen, was notwendig werden kann, wenn über längere Zeit die Filtereinrichtung nicht gereinigt wird und neben der Last der gefilterten Stoffe noch der Wasserdruck aufzufangen ist. Der Fig. 2b ist die Platzierung der Stabilisierungsabschnitte 31 relativ zu dem Ansatzabschnitt bzw. Ansatzring 32 und der Auflageschulter 30 noch deutlicher zu erkennen.According to Fig. 2a is an upper portion 32 a, which is also formed like a ring, to recognize.
