Description

Die Erfindung betrifft eine Entwässerungs- und/oder Drainagevorrichtung (nachfolgend Entwässerungsvorrichtung genannt), wie sie beispielsweise zur Versickerung von Oberflächenwasser Verwendung findet.The invention relates to a drainage and / or drainage device (hereinafter called dewatering device), as used for example for the infiltration of surface water.

Es ist bekannt, Oberflächenwasser in unterirdische Hohlräume einzuleiten, die durch Gitterstrukturelemente ausgefüllt sind. Ein Beispiel für eine derartige Entwässerungsvorrichtung findet sich in DE 20 2004 018 319 U1 und in DE 299 24 050 U1 .It is known to introduce surface water into underground cavities which are filled by lattice structural elements. An example of such a dewatering device can be found in DE 20 2004 018 319 U1 and in DE 299 24 050 U1 ,

Die bekannten Entwässerungsvorrichtungen weisen eine kastenförmige Struktur auf und bestehen im Regelfall aus Kunststoff. Sie sind in Spritzgusstechnik gefertigt. Da die bekannten Entwässerungsvorrichtungen dreidimensional durchströmbar sind, weisen sie in mehreren Richtungen verlaufende Durchbrechungen auf. Werden derartige Gitterstrukturen im Spritzgussverfahren hergestellt, bedeutet dies wegen der kreuz und quer verlaufenden Gitteröffnungen eine komplizierte Schiebertechnik und aufwändige Spritzgussformen. Aus diesem Grunde ist in der bereits oben erwähnten DE 299 23 050 U1 beschrieben, einen Drainagekasten aus zwei gleichen Halbkästen herzustellen. Allerdings erfordert die Herstellung eines Halbkastens bereits eine aufwändige Schieber- und Spritzgussformtechnik.The known dewatering devices have a box-shaped structure and are usually made of plastic. They are manufactured in injection molding technology. Since the known dewatering devices are flowed through three-dimensionally, they have in several directions extending openings. If such grating structures produced by injection molding, this means because of the criss-cross grid openings a complicated slide technology and complex injection molds. For this reason, in the already mentioned above DE 299 23 050 U1 described to produce a drainage box from two equal half-boxes. However, the production of a half-box already requires a complex slide and injection molding technique.

Aus EP-A-1 607 535 ist eine Drainagebox bekannt, die aus mehreren gleichen, im Wesentlichen W-förmigen Kunststoff-Gitterelementen zusammengesetzt ist. Jedes einteilige Gitterelement weist eine Gitterbasisplatte mit an zwei gegenüberliegenden Enden aufragenden Seitengitterrändern auf. Zwischen diesen beiden Seitengitterrändern erstreckt sich, ebenfalls von der Gitterbasisplatte aufragend eine Mittengittererhebung, die das Gitterelement in zwei gleiche Teilabschnitte mit jeweils einem Halbdurchlass unterteilt. Durch die Gitterbasisplatte erstreckt sich eine erste Gruppe von zueinander parallelen Gitteröffnungen, während die Seitengitterränder eine zweite Gruppe von Gitteröffnungen aufweisen, die parallel zueinander, jedoch quer zu den Gitteröffnungen der Gitterbasisplatte verlaufen. Zur Bildung einer Gitterbox werden nun zwei Gitterelemente zusammengesetzt, indem ihre Seitengitterränder und Mittengittererhebungen aneinander liegen, wobei diese Gitterbox zwei parallel verlaufende Durchlässe aufweist. Mehrere derartige Gitterboxen können neben- und/oder übereinander angeordnet werden.Out EP-A-1 607 535 a drainage box is known, which is composed of a plurality of identical, substantially W-shaped plastic grid elements. Each one-piece grid element has a grid base plate with upstanding at two opposite ends of the side grid edges. Between these two side rail edges extends, also from the grid base plate towering a Mittengittererhebung, which divides the grid element into two equal sections, each with a half-passage. Through the grid base plate, a first group of grid openings parallel to each other extends, while the side grid edges have a second group of grid openings that are parallel to each other but transverse to the grid openings of the grid base plate. To form a lattice box, two lattice elements are now assembled by their side lattice edges and center lattice elevations are adjacent to each other, this lattice box two parallel Having passages. Several such grid boxes can be arranged side by side and / or one above the other.

Aus EP-A-1 437 305 ist eine Drainagevorrichtung bekannt, die aus einzelnen unterschiedlich großen ebenen Gitterplatten zusammengesetzt ist.Out EP-A-1 437 305 a drainage device is known, which is composed of individual differently sized flat grid plates.

EP-A-1 437 305 offenbart die Merkmale des einleitenden Teils des Anspruchs 1. EP-A-1 437 305 discloses the features of the introductory part of claim 1.

Aufgabe der Erfindung ist es, eine Entwässerungs- und/oder Drainagevorrichtung zu schaffen, die sich kostengünstig und ohne großen Aufwand in Spritzgusstechnik herstellen lässt.The object of the invention is to provide a drainage and / or drainage device that can be produced inexpensively and without great effort in injection molding.

Zur Lösung dieser Aufgabe wird mit der Erfindung eine Entwässerungs- und/oder Drainagevorrichtung vorgeschlagen, die versehen ist mit den Merkmalen des Anspruchs 1. Verschiedene Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.To solve this problem, a drainage and / or drainage device is proposed with the invention, which is provided with the features of claim 1. Various embodiments of the invention are the subject of the dependent claims.

Erfindungsgemäß ist die Entwässerungsvorrichtung aus mindestens drei Teilen aufgebaut, wobei jedes Teil Gitteröffnungen aufweist, die sämtlich pro Teil parallel zueinander verlaufen. Ein solches Gitterelement lässt sich auf denkbar einfache Art und Weise in Spritzgusstechnik herstellen, da für die Entformung keine Schieber erforderlich sind, sondern die Entformung automatisch durch das Auseinanderfahren der Spritzgussformen erfolgt. Diese Gitterelemente werden aneinander gesetzt, was beispielsweise durch Rastverbindungen, Kleben oder Schweißen oder separate Verbindungselemente erfolgt. Mindestens drei dieser Elemente ergeben zusammen die erfindungsgemäße Entwässerungsvorrichtung, wobei die Gitteröffnungen jedes Elements in einem der Teilung entsprechenden Umfangswinkel versetzt zueinander verlaufen (120° bei dreiteiliger und 90° bei vierteiliger Gitterstruktur).According to the invention, the dewatering device is made up of at least three parts, each part having lattice openings, all of which run parallel to each other per part. Such a grid element can be produced in a very simple manner in injection molding technology, since no slides are required for demolding, but the demolding is done automatically by moving apart of the injection molds. These grid elements are placed against each other, which is done for example by snap-in connections, gluing or welding or separate fasteners. At least three of these elements together form the dewatering device according to the invention, the grid openings of each element being offset relative to one another at a circumferential angle corresponding to the division (120 ° for three-part and 90 ° for four-part grid structure).

Erfindungsgemäß wird also die kasten- oder rohrförmige Entwässerungsvorrichtung aus mehreren, d. h. mindestens drei gleichen Teilen hergestellt, durch die sich Gitteröffnungen erstrecken, die sämtlich pro Teil parallel zueinander verlaufen. Vorzugsweise lässt sich mit diesen Teilen auch beispielsweise eine achtteilige Gitterstruktur aufbauen. Die Teilung erfolgt dabei alle jeweils 45°. Wenn die Gitterstruktur eine äußere Kastenform aufweist, so weist jede Seite der Gitterstruktur zwei gleiche Teile auf, die in der Mitte auf Stoss aneinander liegen und an den Ecken auf Gehrung an ein jeweils benachbartes Teil der Gitterstruktur angeordnet sind. Die Anordnung auf Gehrung ist zweckmäßigerweise auch bei einer vierteiligen Ausgestaltung der Gitterstruktur gegeben.According to the invention, therefore, the box or tubular dewatering device is made of several, ie at least three equal parts, through which grid openings extend, all of which run parallel to each other per part. Preferably, for example, an eight-part lattice structure can also be constructed with these parts. The division is done every 45 °. If the grid structure has an outer box shape, then each side faces the lattice structure on two equal parts, in the middle on impact to each other lie and are mitred at the corners to a respective adjacent part of the grid structure. The miter arrangement is expediently also given a four-part design of the grid structure.

Zur Erhöhung der Stabilität der erfindungsgemäßen kasten- oder rohrförmigen Entwässerungsvorrichtung ist mit Vorteil vorgesehen, in dem Durchlass eine Stützwand vorzusehen, die sich in diametral gegenüberliegenden Bereichen zweier Teile der Gitterstruktur an diesen abstützt. Hierdurch können je nach Höhe des Erdreichs über der in den Boden eingelassenen Entwässerungsvorrichtung Druckkräfte aufgenommen werden. Die Stützwand kann also (in der Einbaulage der Entwässerungsvorrichtung) vertikal, aber auch horizontal ausgerichtet sein. Im letztgenannten Fall stabilisiert die Stützwand die Gitterstruktur der erfindungsgemäßen Entwässerungsvorrichtung gegen seitlich anstehende Erddrücke. Die Stützwand kann offen, beispielsweise als Gitterstruktur, oder geschlossen ausgebildet sein. Mit anderen Worten kann die Stützwand also Durchgangsaussparungen aufweisen. Die Befestigung der Stützwand an deren Kontaktflächen mit den betreffenden Teilen der Gitterstruktur kann durch Einrasten oder durch eine andere kraftschlüssige Verbindung erfolgen.To increase the stability of the box or tubular dewatering device according to the invention is provided with advantage in the passage to provide a support wall which is supported in diametrically opposite areas of two parts of the grid structure of these. As a result, pressure forces can be absorbed depending on the height of the soil above the dewatering device embedded in the soil. The support wall can thus (in the installation position of the dewatering device) be vertically aligned, but also horizontally. In the latter case, the supporting wall stabilizes the lattice structure of the dewatering device according to the invention against laterally prevailing earth pressures. The support wall can be open, for example as a lattice structure, or closed. In other words, the support wall can thus have through holes. The attachment of the support wall at the contact surfaces with the relevant parts of the grid structure can be done by snapping or by another non-positive connection.

Die Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung anhand mehrerer unterschiedlicher Ausführungsbeispiele näher beschrieben. Im einzelnen zeigen dabei:

Die Fign. 1 und 2 zeigen ein erstes Ausführungsbeispiel einer kastenförmigen Entwässerungsvorrichtung 10, die eine Gitterstruktur aufweist, welche aus vier gleichen Gitterstrukturteilen 12 aufgebaut ist. Jedes Gitterstrukturteil 12 weist eine Vielzahl von sich kreuzenden längs- und querverlaufenden Gitterstreben 14,16 auf, zwischen denen sich Gitteröffnungen 18 bilden. Die vier Gitterstrukturteile 12 bilden zwischen sich und miteinander einen Durchlass 20, der sich längs durch die kastenförmige Entwässerungsvorrichtung 10 erstreckt. Mit den Gitteröffnungen 18 fluchten an der Innenseite 22 des Durchlasses 20 Öffnungen 24. Im eingebauten Zustand wird um die Entwässerungsvorrichtung 10 ein Vlies (insbesondere Geotextil) gelegt, um die Gitteröffnungen 18 nach außen zu überdecken. Hierdurch wird verhindert, dass Erdreich in die Gitterstruktur eindringt.The FIGS. 1 and 2 show a first embodiment of a box-shaped dewatering device 10 having a grid structure, which is composed of four identical lattice structure parts 12. Each lattice structure part 12 has a plurality of intersecting longitudinal and transverse lattice struts 14, 16, between which lattice openings 18 are formed. The four lattice structure parts 12 form between them and each other a passage 20 which extends longitudinally through the box-shaped dewatering device 10. Openings 24 are aligned with the grid openings 18 on the inside 22 of the passage 20. In the installed state, a nonwoven (in particular geotextile) is placed around the drainage device 10 in order to cover the grid openings 18 to the outside. This prevents soil from entering the lattice structure.

Das zu versickernde Wasser wird über (nicht dargestellte) Abflussrohre in den Durchlass 20 geleitet, wo es über die Öffnungen 24 in die Gitteröffnungen 18 und deren Durchbrüche eindringt und schließlich sich über die gesamte Entwässerungsvorrichtung 10 verteilt. Mehrere Entwässerungsvorrichtungen gemäß Fign. 1 und 2 können neben-, über- und hintereinander angeordnet sein, wobei benachbarte Entwässerungsvorrichtungen durch Loch-Zapfenverbindungen, separate Verbindungselemente oder auf andere Art und Weise gegen unbeabsichtigte Relativverschiebungen gesichert sein können.The water to be seeped is led via discharge pipes (not shown) into the passage 20, where it penetrates through the openings 24 into the grid openings 18 and their openings and finally spreads over the entire dewatering device 10. Several dewatering devices according to FIGS. 1 and 2 may be arranged side by side, above and behind each other, wherein adjacent dewatering devices may be secured by pin-and-mortise joints, separate connection elements or in some other way against unintentional relative displacements.

Der Vorteil der Herstellung der Entwässerungsvorrichtung 10 nach Fign. 1 und 2 ist darin zu sehen, dass die Entwässerungsvorrichtung 10 aus vier gleichen Teilen zusammengesetzt ist, wobei jedes Gitterstrukturteil 12 auf einfache Art und Weise in Spritzgusstechnik herstellbar ist. Da sämtliche Gitteröffnungen 18 eines jeden Gitterstrukturteils 12 parallel zueinander verlaufen, kann die Entformung des Spritzguss-Gitterstrukturteils 12 durch einfaches Auseinanderfahren der Spritzgussformhälften erfolgen. Eine Schiebertechnik o. dgl. aufwändige Entformungstechnik ist nicht erforderlich.The advantage of producing the dewatering device 10 after FIGS. 1 and 2 is to be seen in that the dewatering device 10 is composed of four equal parts, wherein each lattice structure part 12 can be produced in a simple manner by injection molding. Since all lattice openings 18 of each lattice structure part 12 extend parallel to one another, the demolding of the injection-molded lattice structure part 12 can be achieved by simply moving apart the injection mold halves done. A slide technology o. The like. Elaborate Entformungstechnik is not required.

In Fig. 3 ist eine ebenfalls kastenförmige Entwässerungsvorrichtung 10' gezeigt, in der die den Einzelkomponenten der Entwässerungsvorrichtung 10 gemäß der Fign. 1 und 2 entsprechenden Elemente mit den gleichen Bezugszeichen wie in den Fign. 1 und 2 bezeichnet sind. Der Unterschied der Entwässerungsvorrichtung 10' gegenüber der Entwässerungsvorrichtung 10 der Fign. 1 und 2 besteht in der Unterteilung der Entwässerungsvorrichtung in die einzelnen Gitterstrukturteile 12. Während sich diese Teile 12 bei dem Ausführungsbeispiel gemäß den Fign. 1 und 2 längs der Kanten der kastenförmigen Entwässerungsvorrichtungen 10 erstrecken und damit relativ flach sind, verlaufen die Gitterstrukturteile 12 bei der Entwässerungsvorrichtung 10' der Fig. 3 über Eck, so dass zur Herstellung eines Gitterstrukturteils 12 der Entwässerungsvorrichtung 10' eine etwas höher bauende Spritzgussform als im Falle des Ausführungsbeispiels nach den Fign. 1 und 2 erforderlich ist.In Fig. 3 a likewise box-shaped dewatering device 10 'is shown, in which the individual components of the dewatering device 10 according to the FIGS. 1 and 2 corresponding elements with the same reference numerals as in the FIGS. 1 and 2 are designated. The difference of the dewatering device 10 'with respect to the dewatering device 10 of FIGS. 1 and 2 consists in the subdivision of the dewatering device in the individual lattice structural parts 12. While these parts 12 in the embodiment according to the FIGS. 1 and 2 extend along the edges of the box-shaped dewatering devices 10 and thus are relatively flat, extend the lattice structural parts 12 in the dewatering device 10 'of Fig. 3 corner, so that for producing a lattice structural part 12 of the dewatering device 10 'is a slightly higher-build injection mold than in the case of the embodiment of the FIGS. 1 and 2 is required.

In Fig. 4 ist ein weiteres Ausführungsbeispiel einer kastenförmigen Entwässerungsvorrichtung 10'" gezeigt. Die Gitterstruktur dieser Entwässerungsvorrichtung 10'" weist ebenfalls vier gleiche Gitterstrukturteile 12 auf, die jeweils wiederum aus sich kreuzenden Gitterstreben 14,16 aufgebaut sind. In diesem Ausführungsbeispiel sind die Gitteröffnungen 18 wiederum über Öffnungen 24 zum Durchlass 20 hin offen.In Fig. 4 A further exemplary embodiment of a box-shaped dewatering device 10 '"is shown, The lattice structure of this dewatering device 10'" also has four identical lattice structure parts 12, which are in turn constructed of intersecting lattice struts 14, 16. In this exemplary embodiment, the grid openings 18 are in turn open via openings 24 to the passage 20.

Die Verbindung der Gitterstrukturteile 12 der zuvor beschriebenen Ausführungsbeispiele der Entwässerungsvorrichtung erfolgt vorzugsweise durch Verschweißen, Verkleben oder durch Verriegeln benachbarter Gitterstrukturteile mittels Rast- oder Verbindungselemente. Die Verbindungsstruktur muss so beschaffen sein, dass sie den statischen Lasten, die über das Erdreich auf die Entwässerungsvorrichtung einwirken, standhält.The connection of the lattice structure parts 12 of the above-described embodiments of the dewatering device is preferably carried out by welding, gluing or by locking adjacent lattice structure parts by means of latching or connecting elements. The connection structure shall be such as to withstand the static loads acting on the drainage device via the soil.

In den zuvor beschriebenen Figuren weisen die einzelnen Gitterstrukturteile 12 jeweils eine symmetrische Gitterstruktur auf. Es sei an dieser Stelle erwähnt, dass die Gitterstruktur zweckmäßigerweise auch asymmetrisch sein kann (bezogen auf eine in Längserstreckung verlaufende oder quer dazu verlaufende Symmetrieachse). Auch ist es möglich, bei geringeren im Einbauzustand zu erwartenden Belastungen die Gitterstrukturteile 12 der Figuren ihrerseits jeweils aus zwei gleichen Einzelteilen zusammenzusetzen, wie es in den Fign. 1 und 4 bei 25 angedeutet gezeigt ist. Damit würden z. B. die Entwässerungsvorrichtungen der Fign. 1 und 4 aus acht gleichen Gitterstrukturteilen bestehen (symmetrische Teilung der Teile in Längserstreckung der Durchlässe angenommen).In the figures described above, the individual lattice structure parts 12 each have a symmetrical lattice structure. It should be mentioned at this point that the grid structure can expediently also be asymmetrical (with respect to a longitudinal axis extending or transverse thereto symmetry axis). It is also possible, in the case of lower loads to be expected in the installed state, to compose the lattice structure parts 12 of the figures in turn from two identical individual parts, as shown in FIGS FIGS. 1 and 4 indicated at 25 is shown. This would z. B. the dewatering devices of FIGS. 1 and 4 consist of eight equal lattice structural parts (symmetrical division of the parts in the longitudinal extension of the passages assumed).

Zusätzlich kann eine Stützwand 26 in dem Durchlass 20 angeordnet sein, wie gezeigt ist. Die Stützwand 26 ist in diesem Ausführungsbeispiel mit Durchgangsaussparungen versehen, die sich als Öffnungen zwischen benachbarten Gitterstreben der Stützwand 26 bilden. Die Stützwand 26 stützt zwei gegenüberliegende Gitterstrukturteile 12 ab, wodurch die Stabilität der Entwässerungsvorrichtung 10 "' erhöht ist.In addition, a support wall 26 may be disposed in the passage 20, as shown. The support wall 26 is provided in this embodiment with through holes, which form as openings between adjacent lattice struts of the support wall 26. The support wall 26 supports two opposing lattice structure parts 12, whereby the stability of the dewatering device 10 "'is increased.
