Definitions
- the invention relates to a system for producing one or more seepage tunnels with at least one vault module, which is formed from an arcuate wall, wherein the wall along their longitudinal edges each have a support edge for the flat support of the open vault module on a flat, in the direction of their longitudinal extension one behind the other arranged stiffening ribs and is pierced by a plurality of seepage openings and the support edges are supported by means of stiffening fingers against the wall.
- Such a vault module is from the US-A-2002/0044833 previously known. Moreover, from the WO 03/100180 A2 a vault module is known, which can be assembled by means of various connection modules in rows to a seepage tunnel, the tunnel can also run around curves and corners.
- such vault modules serve for drainage of land.
- the rainwater accumulating on roofs, balconies or even concrete or paved areas is usually supplied to the drain by means of the roof slope or a slope provided in the area to be drained, which in turn supplies the water to the sewer.
- the above-mentioned infiltration tunnels now provide a solution for creating both the space required for infiltration and the traffic areas such as roads and parking lots from the water.
- a planum ie a flat surface which is formed of gravel, is prepared first.
- the seepage tunnels made up of vault modules are placed and, if necessary, connected to the planum.
- the vaults created in this way are covered with soil and can then be entered, transplanted and even driven on.
- a supply line for filling the tunnel for example, by a connection to the gutter or a drain. Water collected in the tunnel will now be slowly and continuously released into the soil and will no longer be sent to the sewers and thus to the rivers. The prerequisite for this, however, is that the soil is also able to be infiltrated.
- the US 2003/0161685 A1 also describes such a vault module, in particular a method for their preparation.
- a wire frame is used according to this method, which works out the vault shape of a block of rigid, air-permeable material with a rotating movement.
- the present invention has the object to provide a percolation system, with a much greater efficiency in terms of space requirements for the infiltration of a certain amount of water and at the same time a high degree of stability is ensured.
- the system according to the invention for producing one or more seepage tunnels comprises at least one vault module which has a support edge along its longitudinal edges, on which the vault module can rest on the subgrade.
- the problem here is the pressure exerted from above through the soil on the open vault module, which would push the vault modules into the planum.
- the size of the support edges can not be arbitrarily increased for cost and practical reasons, since the edges tend to break in such a configuration.
- a corresponding contribution to the strength of the support edges make additional stiffening fingers, which support the support edges in their right-angled arrangement with respect to the wall against them.
- the support edges are connected by means of a tapping with a bottom surface, so that the flanks of the vault module are additionally held against the pressure of the soil. Due to the resulting smooth floor surface, it is possible to drive the seepage tunnel with a camera and, if necessary, find faulty spots, blockages or other things of interest in the seepage tunnel.
- the capacity of a seepage tunnel formed from the vault modules according to the invention can be increased by a pyramidal arrangement of the vault modules using the same Verzapfung.
- another vault module is placed above the two lower vault modules, for example in the middle, on the convex arched arches, and the upper one is connected to the two lower vault modules by means of the mentioned tapping. From the upper vault module, the water contained therein can infiltrate down into the two underlying vault modules. Thereby The storage capacity of the seepage tunnel formed by the vault modules increases considerably and the rainwater can be discharged continuously over a longer period of time.
- the maintenance aspect is further supported by the fact that in the middle of the bottom surface of a channel runs, in which any deposits flow. Such a gutter is easy to clean using appropriate cleaning equipment.
- the vault module As far as the vault module is placed directly on the subgrade, it is advantageous to additionally connect the relevant module to the ground by means of a ground anchor driven by one of the support edges. As a result, it is avoided that shifts occur when filling the seepage tunnel. After the seepage tunnels are mostly filled in with construction machinery, a large amount of material may press asymmetrically on one side of the modules and displace the pressure due to displacement. With the aid of the ground anchor, the modules fixed in this way are each held in at least one place.
- the vault module according to the invention is also designed so that it can be combined with a second vault module as needed to form a double volume seepage tunnel.
- an open vault module is first placed on the planum so that the Arch vault to planum points.
- a second open vault module is placed with its support edges so that a tube, thus a closed vault module is formed.
- the vault modules offset in the longitudinal direction in order to achieve a greater degree of rigidity. Then, however, the offset must be equalized at both ends of the seepage tunnel.
- the interconnected support edges additionally avoid pushing apart the Gewölbedeem.
- anti-tipper means are provided on the convex vault side. These are essentially formed of a strut, which forms a straight resting edge, so that the module rests on this edge and is no longer movable on the arc rounding.
- the lower arch module has no seepage openings.
- Such a module can be used as a cistern so that water can be stored for removal.
- no bottom surface is used in a two-shell arrangement. Rather, a bottom plate is inserted into the lower module, which as well as the bottom plate is camera-driven. In addition, this floor plate can if necessary by means of margins to a gutter be reformed, which in turn can be easily cleaned with cleaning equipment.
- a cistern or a seepage tunnel can also be constructed in such a way that alternating vault modules with individually arranged open vault modules are combined to form an overall arrangement.
- a plurality of analogously structured layers can be combined with each other in this arrangement, wherein for reasons of stability, a staggered position to position arrangement is selected.
- the strength against the soil pressing from above can be improved as an alternative or in addition to a bottom surface, that means for cross-bracing between two opposite support edges are introduced so that even with greater pressure, the support edges can not be pushed apart due to the tension of the means for cross-bracing ,
- the transverse reinforcement can be realized both as a material strip connected to the support edges, and also as a chain or band.
- this means for cross-bracing is connected by means of a tapping with the support edges.
- This type of connection is on the one hand very durable, as by the use of solid, possibly metal, pin a long life is achieved, on the other hand, it is easy to open, should take place once a conversion or about an extension of a seepage tunnel.
- the bumps distributed periodically over the vaulted ridges of the module, from which the stiffening ribs are formed, are also internally supported by means of stiffening means. Since these directly oppose the pressure by their highlighted position, so a yielding of the wall is avoided.
- an overhead module rests with its inner wall surface on the module below. Where this is not possible, it rests on the stiffeners of the periodic elevations, which are perpendicular stand on the lower surface and thus can absorb the greatest pressure.
- vault modules for example terminal modules, can be closed with an end wall, which is preferably also equipped with a tongue and groove connection.
- the front wall recesses for example, provided for cleaning or camera handling of the seepage tunnel, which are preferably initially closed.
- the required recesses can be opened only when installing the end wall.
- the recesses can be used as inlet or as overflow of the modules.
- the modules are usually fed by water infiltrating from the surface of the earth and by water introduced from gutters or traffic areas, for example. While the former penetrates by itself through the vault walls, the latter must be introduced into the seepage tunnel by means of pipes and hoses.
- the housing module engages over an area which corresponds approximately to the transport surface of a Euro pallet.
- two vault modules can be laid one above the other stacked. This can be on site in a structurally simplest way double-walled seepage tunnel with correspondingly increased load capacity can be created.
- FIG. 1 shows a vault module 1 to form a seepage tunnel, which is formed from an arcuate wall 2.
- the vault module 1 is reinforced by means of stiffening ribs 5, which better support the pressure of the surrounding soil.
- the wall 2 is penetrated by a plurality of seepage openings 6 through which the rainwater to be seeped through the wall 2 can pass.
- a seepage tunnel is created by juxtaposing vault modules 1, which are connected together in series by means of a tongue and groove system 10.
- the area to be dewatered is first dug out and a subsurface 17 is created. This is fixed with gravel and carries the seepage tunnel.
- the vault modules 1 are placed on the planum 17 and optionally with anchored to this.
- the vault wall along its longitudinal edges supporting edges 4, which are supported with the vault module 1 with its surface.
- the pressure of the soil from above is additionally supported by means of the support edges 4.
- the rainwater to be seeped passes either via the seepage openings 6 or through supply lines into the seepage tunnel. There it can be stored first and then gradually released to the surrounding soil.
- FIG. 2 shows how a vault module 1 can be greatly increased by assigning a second, along its longitudinal axis rotated by 180 °, vault module.
- the doubled capacity of the seepage tunnel is suitable for larger areas or larger amounts of water.
- the stability of the housing modules is ensured by means of anti-tilt device 7, which hold the modules 1,1 'in an upright position.

Description
Die Erfindung betrifft ein System zur Herstellung eines oder mehrer Sickertunnel mit wenigstens einem Gewölbemodul, welches aus einer bogenförmig ausgebildeten Wandung gebildet ist, wobei die Wandung entlang ihrer Längskanten jeweils einen Stützrand zur flachen Abstützung des offenen Gewölbemoduls auf einem Planum aufweist, in Richtung ihrer Längserstreckung hintereinander angeordnete Versteifungsrippen aufweist und von einer Vielzahl von Sickeröffnungen durchbrochen ist und die Stützränder mithilfe von Versteifungsfingern gegen die Wandung abgestützt sind.The invention relates to a system for producing one or more seepage tunnels with at least one vault module, which is formed from an arcuate wall, wherein the wall along their longitudinal edges each have a support edge for the flat support of the open vault module on a flat, in the direction of their longitudinal extension one behind the other arranged stiffening ribs and is pierced by a plurality of seepage openings and the support edges are supported by means of stiffening fingers against the wall.

Aus dem europäischen Patent
Bei der vorbekannten Ausführung scheint aber die der gewünschten Stabilität der Sickerkammer geschuldete sehr ausgeprägte Außenverrippung die Stapelbarkeit der Sickermodule zu beeinträchtigen oder zumindest den Platzbedarf der gestapelten Sickermodule beträchtlich zu erhöhen.In the prior art design, however, the very pronounced external ribbing due to the desired stability of the seepage chamber appears to affect the stackability of the seepage modules, or at least substantially increase the footprint of the stacked seepage modules.
Allgemein dienen solche Gewölbemodule, und insbesondere die daraus herstellbaren Sickertunnel, zur Entwässerung von Grundstücken. Das auf Dächern, Balkonen oder auch betonierten oder gepflasterten Flächen anfallende Regenwasser wird üblicherweise mithilfe der Dachneigung oder einem in der zu entwässernden Fläche vorgesehenen Gefälle einem Abfluss zugeführt, welche ihrerseits das Wasser der Kanalisation zuleitet.In general, such vault modules, and in particular the seepage tunnels that can be produced therefrom, serve for drainage of land. The rainwater accumulating on roofs, balconies or even concrete or paved areas is usually supplied to the drain by means of the roof slope or a slope provided in the area to be drained, which in turn supplies the water to the sewer.
In der Vergangenheit hat dies vermehrt dazu geführt, dass die Flüsse besonders viel Wasser führten, weil das Wasser, das normalerweise auf den Landflächen versickern würde, den Flüssen über Kanäle zugeführt wurde. Stromabwärts sammelt sich auf diese Weise wesentlich mehr Wasser, je mehr Flächen der Natur als Versickerungsflächen durch Versiegelung genommen werden.In the past, this has increasingly led to the rivers feeding a great deal of water, because the water that would normally seep into the land was fed to the rivers via canals. Downstream collects In this way, significantly more water, the more surfaces of nature are taken as infiltration surfaces by sealing.
Umgekehrt ist es unerlässlich, etwa Verkehrsflächen frei von Wasser zu halten, da die Führer von Fahrzeugen bei Aquaplaning die Kontrolle über ihr Fahrzeug verlieren und so einen Unfall verursachen können. Ebenso ist es nachteilig, das auf einem Dach niedergeschlagene Wasser als Schwall durch den Garten fließen zu lassen, da dies den Boden aufweichen und im schlimmsten Fall die Bepflanzung zerstören würde.Conversely, it is essential to keep traffic areas clear of water, as aquaplaning vehicles can cause vehicle drivers to lose control of their vehicle and cause an accident. It is also disadvantageous to let the water deposited on a roof flow as a surge through the garden, as this would soften the ground and in the worst case would destroy the planting.
Die genannten Versickerungstunnels stellen nunmehr eine Lösung dar, sowohl den benötigten Raum für Versickerung zu schaffen, als auch die Verkehrsflächen wie Straßen und Parkplätze vom Wasser freizuhalten. In einer ausgehobene Grube wird zunächst ein Planum, also eine ebene Fläche welche etwa aus Schotter gebildet ist, vorbereitet. Darauf werden die aus Gewölbemodulen zusammengesetzten Sickertunnel aufgesetzt und diese gegebenenfalls mit dem Planum verbunden. Die so geschaffenen Gewölbe werden mit Erdreich zugedeckt und können anschließend betreten, überpflanzt und sogar befahren werden.The above-mentioned infiltration tunnels now provide a solution for creating both the space required for infiltration and the traffic areas such as roads and parking lots from the water. In an excavated pit, a planum, ie a flat surface which is formed of gravel, is prepared first. On top of this, the seepage tunnels made up of vault modules are placed and, if necessary, connected to the planum. The vaults created in this way are covered with soil and can then be entered, transplanted and even driven on.
Eine Zuleitung zur Befüllung des Tunnels erfolgt beispielsweise durch einen Anschluss an die Dachrinne oder einen Abfluss. In dem Tunnel gesammeltes Wasser wird nun langsam und kontinuierlich in das Erdreich abgegeben und wird nicht mehr der Kanalisation und damit den Flüssen zugeleitet. Voraussetzung hierfür ist allerdings, dass das Erdreich auch versickerungsfähig ist.A supply line for filling the tunnel, for example, by a connection to the gutter or a drain. Water collected in the tunnel will now be slowly and continuously released into the soil and will no longer be sent to the sewers and thus to the rivers. The prerequisite for this, however, is that the soil is also able to be infiltrated.
Die
Ebenfalls bekannt ist es aus der
All diesen Gewölbemodulen ist jedoch der Nachteil gemein, dass lediglich eine sehr beschränkte Menge von Wasser über den aus solchen Modulen entstehenden Tunnel versickern kann. Für eine Vergrößerung der Kapazität der bekannten Sickertunnel ist es stets nötig, eine größere Fläche, also ein größeres Planum bereitzustellen. Zudem bringt es Probleme mit sich, beispielsweise höhere oder breitere Gewölbe herzustellen, da diese nicht mehr genügend Festigkeit aufbringen, um das darüber liegende Erdreich abzustützen.However, all these vault modules have the disadvantage in common that only a very limited amount of water can seep through the tunnel resulting from such modules. For an increase in the capacity of the known seepage tunnels, it is always necessary to provide a larger area, ie a larger planum. In addition, it brings problems with, for example, produce higher or wider vaults, as they no longer muster enough strength to support the overlying soil.
Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Versickerungssystem zu schaffen, mit dem eine wesentlich größere Effizienz in Bezug auf den Platzbedarf für die Versickerung einer bestimmten Wassermenge und gleichzeitig ein hohes Maß an Stabilität gewährleistet wird.Against this background, the present invention has the object to provide a percolation system, with a much greater efficiency in terms of space requirements for the infiltration of a certain amount of water and at the same time a high degree of stability is ensured.
Die Lösung dieser Aufgabe gelingt mithilfe eines SystemS gemäß den Merkmalen des Anspruchs 1 oder 3. Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The solution of this problem is achieved by means of a system according to the features of
Das erfindungsgemäße System zur Herstellung eines oder mehrer Sickertunnel umfasst wenigstens ein Gewölbemodul, das entlang seiner Längskanten jeweils einen Stützrand aufweist, auf dem das Gewölbemodul auf dem Planum aufliegen kann. Problematisch ist dabei der von oben durch das Erdreich auf das offene Gewölbemodul ausgeübte Druck, der die Gewölbemodule in das Planum hineindrücken würde. Je größer dabei die Stützränder ausgeprägt sind, desto mehr Druck kann dadurch aufgenommen werden. Die Größe der Stützränder kann aus Kosten- und praktischen Gründen nicht beliebig vergrößert werden, da die Ränder in einer solchen Konfiguration zum Brechen neigen. Einen entsprechenden Beitrag zur Festigkeit der Stützränder leisten zusätzliche Versteifungsfinger, welche die Stützränder in ihrer rechtwinkligen Anordnung bezüglich der Wandung gegen diese abstützen. Die Stützränder sind mittels einer Verzapfung mit einer Bodenfläche verbunden, so dass die Flanken des Gewölbemoduls zusätzlich gegen den Druck des Erdreichs gehalten sind. Durch die so entstehende glatte Bodenfläche ist es möglich, den Sickertunnel mit einer Kamera zu befahren und gegebenenfalls schadhafte Stellen, Verstopfungen oder andere Dinge von Interesse in dem Sickertunnel aufzufinden. Außerdem kann mithilfe derselben Verzapfung auch die Kapazität eines aus den erfindungsgemäßen Gewölbemodulen gebildeten Sickertunnels durch eine pyramidenförmige Anordnung der Gewölbemodule erhöht werden. Hierzu wird oberhalb von zwei unteren Gewölbemodulen, beispielsweise mittig, auf den konvexen Bogenwölbungen ein weiteres Gewölbemodul aufgelegt und das obere mit den beiden unteren Gewölbemodulen mittels der erwähnten Verzapfung verbunden. Aus dem oberen Gewölbemodul kann das darin enthaltene Wasser nach unten in die beiden darunter liegenden Gewölbemodule einsickern. Dadurch vergrößert sich die Speicherkapazität des aus den Gewölbemodulen gebildeten Sickertunnels erheblich und das Regenwasser kann über einen längeren Zeitraum hinweg kontinuierlich abgegeben werden.The system according to the invention for producing one or more seepage tunnels comprises at least one vault module which has a support edge along its longitudinal edges, on which the vault module can rest on the subgrade. The problem here is the pressure exerted from above through the soil on the open vault module, which would push the vault modules into the planum. The larger the support margins are pronounced, the more pressure can be absorbed thereby. The size of the support edges can not be arbitrarily increased for cost and practical reasons, since the edges tend to break in such a configuration. A corresponding contribution to the strength of the support edges make additional stiffening fingers, which support the support edges in their right-angled arrangement with respect to the wall against them. The support edges are connected by means of a tapping with a bottom surface, so that the flanks of the vault module are additionally held against the pressure of the soil. Due to the resulting smooth floor surface, it is possible to drive the seepage tunnel with a camera and, if necessary, find faulty spots, blockages or other things of interest in the seepage tunnel. In addition, the capacity of a seepage tunnel formed from the vault modules according to the invention can be increased by a pyramidal arrangement of the vault modules using the same Verzapfung. For this purpose, another vault module is placed above the two lower vault modules, for example in the middle, on the convex arched arches, and the upper one is connected to the two lower vault modules by means of the mentioned tapping. From the upper vault module, the water contained therein can infiltrate down into the two underlying vault modules. Thereby The storage capacity of the seepage tunnel formed by the vault modules increases considerably and the rainwater can be discharged continuously over a longer period of time.
Der Wartungsaspekt wird noch dadurch unterstützt, dass in der Mitte der Bodenfläche eine Rinne verläuft, in welche eventuelle Ablagerungen einfließen. Eine solche Rinne ist mithilfe entsprechender Reinigungsgeräte leicht zu reinigen.The maintenance aspect is further supported by the fact that in the middle of the bottom surface of a channel runs, in which any deposits flow. Such a gutter is easy to clean using appropriate cleaning equipment.
Soweit das Gewölbemodul direkt auf dem Planum aufgesetzt ist, ist es vorteilhaft, das betreffende Modul zusätzlich mittels eines durch einen der Stützränder getriebenen Erdankers mit dem Boden zu verbinden. Dadurch ist es vermieden, dass beim Zuschütten des Sickertunnels zu Verschiebungen kommt. Nachdem die Sickertunnel meist mithilfe von Baumaschinen zugeschüttet werden, kann es vorkommen, dass eine große Menge Material unsymmetrisch auf eine Seite der Module drückt und diese dem Druck durch Verschiebung ausweichen. Mithilfe des Erdankers sind die derart fixierten Module jeweils an wenigstens einer Stelle festgehalten.As far as the vault module is placed directly on the subgrade, it is advantageous to additionally connect the relevant module to the ground by means of a ground anchor driven by one of the support edges. As a result, it is avoided that shifts occur when filling the seepage tunnel. After the seepage tunnels are mostly filled in with construction machinery, a large amount of material may press asymmetrically on one side of the modules and displace the pressure due to displacement. With the aid of the ground anchor, the modules fixed in this way are each held in at least one place.
Das erfindungsgemäße Gewölbemodul ist darüber hinaus so beschaffen, dass es mit einem zweiten Gewölbemodul nach Bedarf zu einem Sickertunnel von doppeltem Volumen kombiniert werden kann. Für eine solche Vergrößerung der Kapazität des Sickertunnels wird zunächst ein offenes Gewölbemodul so auf dem Planum platziert, dass die Bogenwölbung zum Planum weist. Auf die nach oben ragenden Stützränder wird nun ein zweites offenes Gewölbemodul mit seinen Stützrändern so aufgesetzt, dass eine Röhre, mithin ein geschlossenes Gewölbemodul, entsteht. Es ist dabei auch möglich, die Gewölbemodule in der Längsrichtung versetzt anzuordnen, um ein größeres Maß an Steifheit zu erreichen. Dann muss der Versatz jedoch entsprechend an beiden Enden des Sickertunnels ausgeglichen werden. Die miteinander verbundenen Stützränder vermeiden zusätzlich ein Auseinanderdrücken der Gewölbewände.The vault module according to the invention is also designed so that it can be combined with a second vault module as needed to form a double volume seepage tunnel. For such an increase in the capacity of the seepage tunnel, an open vault module is first placed on the planum so that the Arch vault to planum points. On the upstanding supporting edges now a second open vault module is placed with its support edges so that a tube, thus a closed vault module is formed. It is also possible to arrange the vault modules offset in the longitudinal direction in order to achieve a greater degree of rigidity. Then, however, the offset must be equalized at both ends of the seepage tunnel. The interconnected support edges additionally avoid pushing apart the Gewölbewände.
Da das zuerst auf dem Planum in Position gebrachte Gewölbemodul durch die Rundheit ihrer wandung nicht notwendig gerade liegt, was zu Problemen beim Zusammenbau der Sickertunnel führen kann, sind auf der konvexen Gewölbeseite Mittel zur Kippsicherung vorgesehen. Diese sind im Wesentlichen aus einer Verstrebung gebildet, welche eine gerade Aufliegekante bildet, so dass das Modul auf dieser Kante ruht und nicht mehr auf der Bogenrundung beweglich ist.Since the vault module first brought into position on the subgrade is not necessarily straight due to the roundness of its wall, which can lead to problems in assembling the seepage tunnels, anti-tipper means are provided on the convex vault side. These are essentially formed of a strut, which forms a straight resting edge, so that the module rests on this edge and is no longer movable on the arc rounding.
Alternativ zur reinen Versickerung kann es in einer nicht beanspruchten Ausführungsform von Vorteil sein, wenn das untere Gewölbemodul keine Sickeröffnungen aufweist. Ein solches Modul kann als Zisterne verwendet werden so dass auch Wasser zur Entnahme gespeichert werden kann.As an alternative to pure infiltration, it may be advantageous in a non-claimed embodiment if the lower arch module has no seepage openings. Such a module can be used as a cistern so that water can be stored for removal.
Generell wird in einer zweischalig aufgebauten Anordnung keine Bodenfläche eingesetzt. Vielmehr wird eine Bodenplatte in das untere Modul eingelegt, welche ebenso wie die Bodenplatte kamerabefahrbar ist. Zusätzlich kann diese Bodenplatte bedarfsweise mithilfe von Randbegrenzungen zu einer Rinne umgebildet sein, welche dann wiederum mit Reinigungsgeräten leicht gesäubert werden kann.Generally, no bottom surface is used in a two-shell arrangement. Rather, a bottom plate is inserted into the lower module, which as well as the bottom plate is camera-driven. In addition, this floor plate can if necessary by means of margins to a gutter be reformed, which in turn can be easily cleaned with cleaning equipment.
In vorteilhafter Ausgestaltung kann eine Zisterne oder ein Sickertunnel auch derart aufgebaut sein, dass im Wechsel zu einander geschlossene Gewölbemodule mit einzeln angeordneten offenen Gewölbemodulen zu einer Gesamtanordnung kombiniert werden.In an advantageous embodiment, a cistern or a seepage tunnel can also be constructed in such a way that alternating vault modules with individually arranged open vault modules are combined to form an overall arrangement.
Dabei können in dieser Anordnung auch mehrere analog aufgebaute Lagen miteinander kombiniert werden, wobei aus Gründen der Stabilität eine von Lage zu Lage versetzte Anordnung gewählt wird.In this case, a plurality of analogously structured layers can be combined with each other in this arrangement, wherein for reasons of stability, a staggered position to position arrangement is selected.
Die Festigkeit gegenüber dem von oben drückenden Erdreich kann alternativ oder ergänzend zu einer Bodenfläche dadurch verbessert werden, dass Mittel zur Querversteifung zwischen zwei gegenüberliegenden Stützrändern so eingebracht werden, dass auch bei größerem Druck die Stützränder aufgrund der Spannung des Mittels zur Querversteifung nicht auseinander gedrückt werden können. Die Querversteifung kann sowohl als ein mit den Stützrändern verbundener Materialstreifen, als auch etwa als Kette oder Band realisiert werden.The strength against the soil pressing from above can be improved as an alternative or in addition to a bottom surface, that means for cross-bracing between two opposite support edges are introduced so that even with greater pressure, the support edges can not be pushed apart due to the tension of the means for cross-bracing , The transverse reinforcement can be realized both as a material strip connected to the support edges, and also as a chain or band.
Mit Vorteil ist dieses Mittel zur Querversteifung mithilfe einer Verzapfung mit den Stützrändern verbunden. Diese Art der Verbindung ist einerseits sehr haltbar, da durch die Anwendung massiver, gegebenenfalls metallener, Zapfen eine große Haltbarkeit erreicht wird, andererseits ist sie leicht zu öffnen, sollte einmal ein Umbau oder etwa eine Erweiterung eines Sickertunnels stattfinden.Advantageously, this means for cross-bracing is connected by means of a tapping with the support edges. This type of connection is on the one hand very durable, as by the use of solid, possibly metal, pin a long life is achieved, on the other hand, it is easy to open, should take place once a conversion or about an extension of a seepage tunnel.
Es hat sich als nützlich erwiesen, zur Verbindung starrer Komponenten eine Nut- und Federverbindung vorzusehen. Insbesondere ist dies auch bei dem erfindungsgemäßen Gewölbemodul von Vorteil, da es sich dabei um eine sehr einfache Verbindung handelt. Die Gewölbe, die im Zuge ihres Aufbaus fest im Erdreich eingeschlossen werden, benötigen keine besonders aufwändige, sondern eine einfache, belastbare Verbindung, da sich der Sickertunnel im Laufe der Zeit nicht mit Erdreich füllen soll.It has proven to be useful to provide a tongue and groove connection for connecting rigid components. In particular, this is also advantageous in the vault module according to the invention, since this is a very simple connection. The vaults, which are firmly embedded in the soil in the course of their construction, do not require a particularly complex, but a simple, strong connection, since the seepage tunnel should not fill with soil over time.
Es sich als vorteilhaft erwiesen, wenn die zur Verbindung mit anderen Modulen verwendeten Nut- und Federverbindungen mithilfe von Dichtungsmitteln wasserdicht verschließbar sind. Dies ist natürlich besonders im Zusammenhang mit solchen Modulen empfehlenswert, die als Zisterne aufgestellt sind.It has proven to be advantageous if the tongue and groove joints used for connection with other modules are sealed watertight using sealants. This is of course especially recommended in connection with such modules, which are set up as a cistern.
Die periodisch über den Gewölberücken des Moduls verteilten Erhebungen, aus denen die Versteifungsrippen gebildet sind, werden inwendig ebenfalls mithilfe von Versteifungsmitteln abgestützt. Da diese durch ihre hervorgehobene Position dem Druck direkt entgegenstehen, wird so ein Nachgeben der Wandung vermieden.The bumps distributed periodically over the vaulted ridges of the module, from which the stiffening ribs are formed, are also internally supported by means of stiffening means. Since these directly oppose the pressure by their highlighted position, so a yielding of the wall is avoided.
Für den Hersteller und den Käufer ist es von großem Interesse, für Lagerhaltung und Transport möglichst geringe Aufwendungen zu haben. Daher hat es sich als vorteilhaft erwiesen, wenn die Gewölbemodule stapelbar sind. Dabei liegt ein oben liegendes Modul soweit möglich mit seiner Wandungsinnenfläche auf dem unten liegenden Modul auf. Wo dies nicht möglich ist, liegt es auf den Versteifungsmitteln der periodischen Erhebungen auf, welche rechtwinklig auf der Unterfläche stehen und somit den größten Druck absorbieren können.For the manufacturer and the buyer, it is of great interest to have the lowest possible expenses for warehousing and transport. Therefore, it has proved to be advantageous if the vault modules are stackable. As far as possible, an overhead module rests with its inner wall surface on the module below. Where this is not possible, it rests on the stiffeners of the periodic elevations, which are perpendicular stand on the lower surface and thus can absorb the greatest pressure.
Mit Vorteil können Gewölbemodule, beispielsweise endständige Module, mit einer Stirnwand abgeschlossen werden, welche vorzugsweise ebenfalls mit einer Nut- und Federverbindung ausgestattet ist.Advantageously, vault modules, for example terminal modules, can be closed with an end wall, which is preferably also equipped with a tongue and groove connection.
In der Stirnwand sind Ausnehmungen, etwa für die Reinigung oder die Kamerabefahrung des Sickertunnels vorgesehen, welche vorzugsweise zunächst verschlossen sind. Je nach Bedarf und Einsatzzweck können die benötigten Ausnehmungen erst beim Einbau der Stirnwand eröffnet werden. Ebenfalls können die Ausnehmungen als Zulauf oder als Überlauf der Module verwendet werden. Die Module werden üblicherweise durch von der Erdoberfläche her einsickerndes Wasser und etwa von Dachrinnen oder Verkehrsflächen her eingeleitetes Wasser gespeist. Während ersteres von selbst durch die Gewölbewände eindringt muss letzteres mithilfe von Rohren und Schläuchen in den Sickertunnel eingeleitet werden.In the front wall recesses, for example, provided for cleaning or camera handling of the seepage tunnel, which are preferably initially closed. Depending on requirements and purpose, the required recesses can be opened only when installing the end wall. Likewise, the recesses can be used as inlet or as overflow of the modules. The modules are usually fed by water infiltrating from the surface of the earth and by water introduced from gutters or traffic areas, for example. While the former penetrates by itself through the vault walls, the latter must be introduced into the seepage tunnel by means of pipes and hoses.
Für einen vereinfachten Transport ist es sinnvoll, wenn das Gehäusemodul eine Fläche übergreift, welche näherungsweise der Transportfläche einer Europalette entspricht. Alternativ bietet es sich an, die Fläche so zu wählen, dass ein ganzzahliges vielfaches der Fläche der Fläche der Palette entspricht. So wird ein effizienter Transport der Gewölbemodule gewährleistet.For a simplified transport, it makes sense if the housing module engages over an area which corresponds approximately to the transport surface of a Euro pallet. Alternatively, it is advisable to choose the surface so that an integer multiple of the surface corresponds to the surface of the pallet. This ensures efficient transport of the vault modules.
In abermals alternativer Anordnung können auch je zwei Gewölbemodule übereinander gestapelt verlegt werden. Hierdurch kann auf konstruktiv einfachste Weise vor Ort ein doppelwandiger Sickertunnel mit entsprechend erhöhter Belastbarkeit geschaffen werden.In another alternative arrangement also two vault modules can be laid one above the other stacked. This can be on site in a structurally simplest way double-walled seepage tunnel with correspondingly increased load capacity can be created.
Die vorstehend beschriebene Erfindung wird im Folgenden in einem Ausfübrungsbeispiel anhand einer schematischen Zeichnung näher erläutert.The invention described above is explained in more detail below in an exemplary embodiment with reference to a schematic drawing.

Dieses wird mit Schotter befestigt und trägt den Sickertunnel. Die Gewölbemodule 1 werden auf das Planum 17 gestellt und gegebenenfalls mit diesem verankert. Zu diesem Zweck weist die Gewölbewand entlang ihrer Längskanten Stützränder 4 auf, welche mit das Gewölbemodul 1 mit ihrer Fläche abstützen. Anschließend wird das Erdreich auf den Sickertunnel aufgefüllt und verdichtet. Der Druck des Erdreichs von oben wird mithilfe der Stützränder 4 zusätzlich abgestützt.To build a seepage tunnel, the area to be dewatered is first dug out and a
