Description

Entwässerunαs- und/oder Drainaαevorrichtunq Drainage and / or drainage device
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 Ul und in DE 299 24 050 Ul.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 Ul and in DE 299 24 050 Ul.
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 herge- stellt, 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 Ul 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 lattice structures are produced by injection molding, this means complicated sliding technology and complex injection molds because of the criss-cross lattice openings. For this reason, described in the already mentioned above DE 299 23 050 Ul 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.
Aufgabe der Erfindung ist es, eine Entwässerungs- und/oder Drainagevorrichtung zu schaffen, die sich kostengünstig und ohne großen Aufwand in Spritzgusstechnik hersteilen lässt.The object of the invention is to provide a drainage and / or drainage device that can be produced inexpensively and without much effort in injection molding.
Zur Lösung dieser Aufgabe wird mit der Erfindung eine Entwässerungs- und/oder Drainagevorrichtung vorgeschlagen, die versehen ist mit einer Gitterstruktur, durch die sich hindurch ein Durchlass zum Einlassen von zu versickernder Fiüssigkeit erstreckt, wobei die Gitterstruktur aus mindestens drei und vorzugsweise vier insbesondere gleichen Teilen besteht, durch die sich jeweils parallel zuein- ander verlaufende Gitteröffnungen erstrecken, die von der Innenseite desTo solve this problem, a drainage and / or drainage device is proposed with the invention, which is provided with a lattice structure through which a passage for the admission of infiltrated liquid to extend, wherein the lattice structure of at least three and preferably four in particular equal parts through which each extending parallel to each other extending grid openings extending from the inside of
Durchlasses bis zur Außenseite der Gitterstruktur verlaufen.Passage extend to the outside of the grid structure.
Erfindungsgemäß ist die Entwässerungsvorrichtung aus mindestens drei Teilen aufgebaut, wobei jedes Teii im wesentlichen in eine Richtung verlaufende GIt- teröffnungen aufweist. Ein solches Gittereiement 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 Gätterelemente 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 Umfangswinke! 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 gate openings extending substantially in one direction. Such a Gittereiement can be produced in a very simple way in injection molding, since no slides are required for demolding, but the demolding is done automatically by moving apart of the injection molds. These Gätterelemente are placed together, which takes place for example by snap-in connections, gluing or welding or separate fasteners. At least three of these elements together constitute the dewatering device according to the invention, wherein the lattice openings of each element in a circumferential swing corresponding to the pitch! offset from one another (120 ° for three-part and 90 ° for four-part lattice structure).
Erfindungsgemäß wird also die kästen- oder rohrförmige Entwässerungsvorrichtung aus mehreren insbesondere 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. Zur Erhöhung der Stabilität der erfindungsgernäßen kästen- 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 Stutzwand kann also (in der Einbaulage der Entwässerungsvorrichtung) vertikal, aber auch horizontal ausgerichtet sein. Im letztgenannten FaIi stabilisiert die Stützwand die Gitterstruktur der erfindungsgemäßen Entwässerungsvorrichtung gegen seitlich an- stehende Erddrücke. Die Stutzwand 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 Verbin- düng erfolgen.According to the invention, therefore, the box or tubular dewatering device is made of several, in particular 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 °. When the grid structure has an outer box shape, each side of the grid structure has two equal parts which abut each other in the center and are mitered 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. To increase the stability of the box or tubular dewatering device according to the invention, it is advantageously provided to provide a support wall in the passage, which wall supports itself in diametrically opposite regions of two parts of the lattice structure. As a result, pressure forces can be absorbed depending on the height of the soil above the dewatering device embedded in the soil. The stucco wall can thus be oriented vertically (but also horizontally in the installation position of the drainage device). In the latter case, the supporting wall stabilizes the lattice structure of the dewatering device according to the invention against laterally applied earth pressures. The stucco wall may be open, for example, as a grid structure, or be formed closed. In other words, the support wall can thus have through holes. The attachment of the support wall at their contact surfaces with the relevant parts of the lattice structure can be made by snapping or by another frictional connection düng.

Fig. 5 eine perspektivische Ansicht einer achtteiligen Gitterstruktur-Entwäs- serungsvorrichtung.5 shows a perspective view of an eight-part lattice structure dewatering device.
Die Fign. 1 und 2 zeigen ein erstes Ausfuhrungsbeispie! einer kastenförmigen Entwässerungsvorrichtung 10, die eine Gitterstruktur aufweist, welche aus vier gieichen Gitterstrukturteilen 12 aufgebaut ist. Jedes Gitterstrukturteil 12 weist eine Vielzahl von sich kreuzenden längs- und querveriaufenden Gitterstreben 14,16 auff zwischen denen sich Gitteröffnungen 18 bilden. Die vier Gitterstrukturteile 12 bilden zwischen sich und miteinander einen Durchlass 20f der sich längs durch die kastenförmige Entwässerungsvorrichtung 10 erstreckt. Mit den Gitteröffnungen 18 fiuchten an der Innenseite 22 des Durchlasses 20 Öff- nungen 24. Im eingebauten Zustand wird um die Entwässerungsvorrichtung 10 ein Vlies (insbesondere GeotextM) gelegt, um die Gitteröffnungen 18 nach außen zu überdecken. Hierdurch wird verhindert, dass Erdreich in die Gitterstruktur eindringt.The Fign. 1 and 2 show a first Ausfuhrungsbeispie! a box-shaped dewatering apparatus 10 having a grid structure composed of four natural grid structure parts 12. Each lattice structure part 12 has a plurality of intersecting longitudinally and transversally running lattice struts 14, 16 on f between which lattice openings 18 are formed. The four lattice structure parts 12 form between them and each other a passage 20 f which extends longitudinally through the box-shaped dewatering device 10. Openings 24 are located on the inner side 22 of the passage 20 with the grid openings 18. In the installed state, a nonwoven (in particular Geotext ™) is placed around the dewatering 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 Durchbruche eindringt und schließlich sich über die gesamte Entwässerungsvorrichtung 10 verteilt. Mehrere Entwässerungsvorrichtungen gemäß Fign. 1 und 2 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 infiltrated is led via discharge pipes (not shown) into the passage 20, where it penetrates via the openings 24 into the lattice 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 against unintentional relative displacements by pin-hole connections, separate connection elements or in another manner.
Der Vorteil bei der Herstellung der Entwässerungsvorrichtung 10 nach Fign. 1 und 2 ist darin zu sehen, dass die Entwässerungsvorrichtung 10 aus vier gieichen Teilen zusammengesetzt ist, wobei jedes Gitterstrukturteil 12 auf einfache Art und Weise in Spritzgusstechnik herstellbar ist Da sämtliche Gitteröff- nungen 18 eines jeden Gitterstrukturteüs 12 paralle! zueinander verlaufen, kann die Entformung des Spritzguss-Gitterstrukturteifs 12 durch einfaches Auseinaπderfahren der Spritzgussforrnhäiften erfolgen. Eine Schiebertechnik o. dgi. aufwändige Entformungstechnik ist nicht erforderlich.The advantage in the production of the dewatering device 10 according to FIGS. 1 and 2 can be seen in that the dewatering device 10 is composed of four parts, wherein each lattice structure part 12 can be produced in a simple manner by injection molding. ments 18 of each lattice structure 12 paralle! extend to each other, the demolding of the injection-lattice Strukturteifs 12 can be done by simply Auseinaπderfahren the Spritzgussforrnhäiften. A slider technique o. Dgi. Complex demolding technique 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 Entwäs- serungsvorrichtung 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 Ausfüh- rungsbeispäel gemäß den Fign. 1 und 2 längs der Kanten der kastenförmigen Entwässerungsvorrichtungen 10 erstrecken und damit relativ flach sind, ver- laufen 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 Ausführungsbeispieis nach den Fign, 1 und 2 erforderlich ist,In Fig. 3 is also a box-shaped dewatering device 10 'is shown, in which the individual components of the dewatering device 10 according to FIGS. 1 and 2 corresponding elements with the same reference numerals as in FIGS. 1 and 2 are designated. The difference between the dewatering device 10 'and the dewatering device 10 of FIGS. 1 and 2 is the subdivision of the dewatering device into the individual lattice structure parts 12. While these parts 12 are shown in the embodiment of FIGS. 1 and 2 extend along the edges of the box-shaped dewatering devices 10 and are thus relatively flat, the lattice structure parts 12 in the dewatering device 10 'of FIG. 3 run at a corner, so that for producing a lattice structure part 12 of the dewatering device 10' a slightly higher Injection mold is required as in the case of Ausführungsbeispieis according to FIGS. 1 and 2,
Fig. 4 zeigt ein Ausführungsbeispiel einer runden bzw. röhrenförmigen Entwässerungsvorrichtung 10", Auch hier gilt, dass diejenigen Elemente, die identisch bzw. gleich den Elementen der Ausführungsbeispiele der Fign. 1 bis 3 sind, mit den gleichen Bezugszeichen gekennzeichnet sind, Jedes Gitterstrukturteil 12 erstreckt sich bei dem Ausführungsbeispiel gemäß Fig. 4 über eine Winkeibe- reich von 90°,4 shows an exemplary embodiment of a round or tubular dewatering device 10 ". Here too, those elements that are identical or identical to the elements of the exemplary embodiments of FIGS. 1 to 3 are identified by the same reference symbols, each grid structure part 12 extends in the embodiment of FIG. 4 over a Winkeibe- range of 90 °,
In Fig. 5 ist ein weiteres Ausführungsbeispiel einer kastenförmigen Entwässerungsvorrichtung 10'" gezeigt. Die Gitterstruktur dieser Entwässerungsvor¬ richtung 10"' weist ebenfalls vier gleiche Gitterstrukturteile 12 auf, die jeweils wiederum aus sich kreuzenden Gitterstreben 14,16 aufgebaut sind. In diesem5 shows a further exemplary embodiment of a box-shaped dewatering device 10 '"The grid structure of this dewatering device 10"' likewise has four identical lattice structure parts 12, which are in turn constructed of intersecting lattice struts 14, 16. In this
Ausführungsbeispiel sind die Gitteröffnungen 18 wiederum über Öffnungen 24 zum Durchlass 20 hin offen. Die Verbindung der Gitterstrukturteile 12 der zuvor beschriebenen Ausfuhrungsbeispiele der Entwässerungsvorrichtung erfolgt vorzugsweise durch Verschweißen, Verkleben oder durch Verriegeln benachbarter Gitterstrukturteile mittels Rast- oder Verbindungselernente, Die Verbindungsstruktur muss so beschaffen sein, dass sie den statischen Lasten, die über das Erdreich auf die Entwässerungsvorrichtung einwirken, standhält.Embodiment, the grid openings 18 are in turn open to the passage 20 through openings 24. The connection of the lattice structure parts 12 of the previously described exemplary embodiments of the dewatering device is preferably carried out by welding, gluing or by locking adjacent lattice structure parts by means of latching or Verbindungselernente, The connection structure must be such that they act on the static loads that affect the dewatering device via the soil, withstand.
In den zuvor beschriebenen Figuren weisen die einzelnen Gitterstrukturteile 12 jeweils eine symmetrische Gitterstruktur auf. Es sei and 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 5 bei 25 angedeutet gezeigt ist. Damit würden z. B. die Entwäs- serungsvorrichtungen der Fign. 1 und 5 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 advantageously also be asymmetrical (with respect to a longitudinal axis extending or transverse thereto symmetry axis), It is also possible at lower expected in the installed state loads the lattice structure parts 12 of the figures in turn each of two to assemble the same components as shown in FIGS. 1 and 5 is indicated at 25 indicated. This would z. For example, the drainage devices of FIGS. 1 and 5 consist of eight equal lattice structural parts (symmetrical division of the parts assumed in the longitudinal extension of the passages).
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 Ent- Wässerungsvorrichtung 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 Ent- washing apparatus 10 '"is increased.
