Description

Die Erfindung betrifft einen Pumpschacht nach dem Oberbegriff des Anspruchs 1, wie er z. B. aus DE 33 11 980 A1 bekannt ist.The invention relates to a pump shaft according to the preamble of claim 1, as he z. B. off DE 33 11 980 A1 is known.

Schächte werden im befahrbaren Bereich in der Regel aus Beton gefertigt. Derartige Schächte, wie sie z. B. auch aus AU 634 778 B2 bekannt sind, haben den Nachteil, dass sie zum einen ab einer bestimmten Größe nicht mehr ohne weiteres oder jedenfalls nur sehr aufwendig zu transportieren und zum anderen den heutigen Abwasserzusammensetzungen nicht mehr gewachsen sind.Shafts are usually made of concrete in the passable area. Such shafts, as z. B. also off AU 634 778 B2 are known, have the disadvantage that on the one hand from a certain size is no longer readily or at least only very expensive to transport and on the other today's wastewater compositions are no longer adequate.

Aus diesem Grund wäre es wünschenswert, auch den Einsatz von anderen Materialien für diesen Anwendungsbereich zu ermöglichen. Kunststoffschächte, wie sie z. B. aus DE 296 01 223 U1 bekannt sind, sind z.B. bisher für die genannten Zwecke nicht oder nur sehr begrenzt einsetzbar, da vor allem Stabilitätsprobleme durch die von oben einwirkenden Lasten bestehen. Zudem besteht bei "leichten" Schächten das Problem der mangelnden Auftriebssicherheit beim Einsatz in Gebieten mit grundwassergefährdeten Bereichen, da das Eigengewicht der Schächte sehr klein ist und letztlich die Gefahr besteht, dass die entsprechenden Schächte aufgeschwemmt werden.For this reason, it would be desirable to allow the use of other materials for this application. Plastic shafts, as z. B. off DE 296 01 223 U1 are known, for example, are not or only very limited use for the purposes mentioned above, because above all stability problems consist of the loads acting from above. In addition, there is the problem of lack of buoyancy in use in areas with groundwater endangered areas in "light" shafts, since the weight of the shafts is very small and ultimately there is a risk that the corresponding shafts are washed up.

Aufgabe der vorliegenden Erfindung ist es daher, einen Pumpschacht der eingangs genannten Art anzugeben, bei dem die genannten Nachteile nicht auftreten oder jedenfalls weitestgehend vermieden werden.Object of the present invention is therefore to provide a pump shaft of the type mentioned, in which the disadvantages mentioned do not occur or at least largely avoided.

Gelöst wird diese Aufgabe mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausführungsformen finden sich in den Unteransprüchen.This problem is solved by the features of claim 1. Advantageous embodiments can be found in the subclaims.

Erfindungsgemäß weist der Pumpschacht eine gewölbte bzw. kugelförmige Oberfläche wenigstens in seinem oberen Bereich auf. Hierdurch wird zum einen die Statik im Hinblick auf höhere Belastbarkeit verbessert, zum anderen wird gleichzeitig die zur Beaufschlagung mit dem Erddruck zur Verfügung stehende Fläche des Pumpschachts erhöht, so dass das Erdreich beim Ansteigen des Grundwassers einen größeren Gegendruck auf den Schacht ausüben kann und somit die Auftriebssicherheit der Einrichtung gesteigert wird. Zur Verankerung im Erdreich ist beim erfindungsgemäßen Pumpschacht eine Verankerungs- oder Aufstelleinrichtung vorgesehen. Die Pumpe ist direkt mit der Verankerungs- oder Aufstellungseinrichtung koppelbar, wobei die Druckleitung wenigstens teilweise in die Verankerungs- oder Aufstelleinrichtung eingebettet und in einem unteren Bereich des Pumpschachtes über eine Rohrdurchführung in der Schachtwand in die Sammelkammer des Pumpschachtes eingeführt ist. Damit kann die Pumpe direkt an der Druckleitung befestigt werden.According to the invention, the pumping shaft has a curved or spherical surface at least in its upper region. On the one hand, the statics with regard to higher load capacity is improved, and on the other hand, the area of the pump shaft which is available for acting on the earth pressure is increased at the same time so that the ground can exert a greater counterpressure on the shaft as the groundwater rises and thus the Buoyancy of the device is increased. For anchoring in the ground an anchoring or setting-up device is provided in the pump shaft according to the invention. The pump can be coupled directly to the anchoring or installation device, wherein the pressure line is at least partially embedded in the anchoring or setting-up device and inserted in a lower region of the pump shaft via a pipe duct in the shaft wall in the collection chamber of the pump shaft. Thus, the pump can be attached directly to the pressure line.

So kann der erfindungsgemäße Pumpschacht aus leichtem Material, vorzugsweise aus Kunststoff durch Rotationssintern oder als Kunststoff-Blasteil, hergestellt werden und erfüllt trotz allem die Anforderungen hinsichtlich der Belastbarkeit auch bei Einbau unterhalb von befahrenem Terrain.Thus, the pump shaft according to the invention of lightweight material, preferably made of plastic by rotational sintering or as a plastic blow-molded, and meets despite all the requirements in terms of resilience even when installed below busy terrain.

Gemäß einer vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass die Verankerungs- oder Aufstelleinrichtung gleichzeitig mit einer im Schacht liegenden Halteeinrichtung für eine Pumpe gekoppelt ist, so dass eine Pumpe von der Verankerungs- oder Aufstelleinrichtung getragen wird. Dies ermöglicht, den Pumpensumpf im Schacht zu Reinigungszwecken zugänglich zu halten und erfordert keine weiteren Haltevorrichtungen im Schacht. Die Erfindung wird nachfolgend anhand der einzigen Zeichnungsfigur schematisch näher erläutert, wobei in der Figur zwei unterschiedliche Ausführungsformen des erfindungsgemäßen Pumpschachts angedeutet sind.According to an advantageous embodiment of the invention, it is provided that the anchoring or setting-up device is coupled simultaneously with a holding device for a pump lying in the shaft, so that a pump is carried by the anchoring or setting-up device. This makes it possible to keep the pump sump in the shaft accessible for cleaning purposes and requires no further holding devices in the shaft. The invention will be explained in more detail schematically with reference to the single drawing figure, wherein in the figure, two different embodiments of the pump shaft according to the invention are indicated.

Der erfindungsgemäße Pumpschacht 1 weist eine im wesentlichen gewölbte, bevorzugt kugelförmige Gestalt auf, in der sich eine Sammelkammer 4 zum Sammeln von Abwasser befindet. Das Abwasser kann mittels einer Pumpe 5, welche über eine Aufhängung oder Halterung 7 (bei der es sich um einen Leitungsanschlußstutzen handeln kann) in einer Sammelkammer hängend gelagert ist, über eine Druckleitung 3 bei Bedarf aus der Sammelkammer 4 herauspumpt werden. Im unteren Bereich weist der Schacht 1 an seiner Außenseite eine mit dem Schacht 1 verbundene oder gekoppelte Verankerungs- oder Aufstelleinrichtung auf, die zum einen dazu dienen kann, den Schacht aufzustellen, zum anderen dazu, den Schacht 1 auftriebssicher zu verankern. Durch die gewölbte bzw. kugelförmige Struktur steht dem Schacht gegenüber bekannten Lösungen eine vergleichsweise große Kontaktfläche mit dem umliegenden Erdreich 6 zur Verfügung, so daß die vom Erdreich auf den Schacht übertragenen Kräfte entsprechend höher ausfallen und einem möglichen Auftreiben des Schachts 1 aufgrund von hohem Grundwasser entgegenwirken können, so daß der Schacht 1 auch bei geringerem Gewicht aufgrund der Verwendung von einem vorzugsweise rotationsgesinterten Kunststoffmaterial auftriebssicher bleibt.The pumping shaft 1 according to the invention has a substantially curved, preferably spherical shape, in which a collection chamber 4 for collecting wastewater is located. The waste water can be pumped out of the collection chamber 4 by means of a pump 5, which is suspended in a collection chamber via a suspension or support 7 (which may be a pipe connection). In the lower region, the shaft 1 on its outer side connected to the shaft 1 or coupled anchoring or Aufstelleinrichtung, which can serve on the one hand to set up the shaft, on the other hand, to anchor the shaft 1 buoyant. Due to the curved or spherical structure, the shaft is opposite known solutions, a comparatively large contact area with the surrounding soil 6 available, so that the forces transmitted from the ground to the shaft correspondingly higher and counteract a possible flooding of the shaft 1 due to high groundwater can, so that the shaft 1 remains buoyant, even at lower weight due to the use of a preferably rotationally sintered plastic material.

Die erforderliche Einbautiefe eines entsprechenden Kugelschachts kann durch Aufsetzen handelsüblicher Schachtringe bzw. Rohre 9 aus Kunststoff oder ähnlichem leichten, korrosionsfestem Material realisiert werden.The required installation depth of a corresponding ball pit can be realized by placing commercially available manhole rings or pipes 9 made of plastic or similar lightweight, corrosion-resistant material.

Die Pumpe 5 kann zudem direkt mit der Verankerungs- oder Aufstelleinrichtung 2, die bevorzugt aus Beton oder Polyurethan (PU)-Schaum besteht, gekoppelt werden. Hierzu wird wenigstens ein Teil der Druckleitung 3 für die Pumpe in die Verankerungs- oder Aufstelleinrichtung 2 eingebettet und in einem unteren Bereich über eine Rohrdurchführung 8 in der Schachtwand in die Sammelkammer 4 an geeigneter Stelle eingeführt. Im Bereich der Durchführung 8 kann dann auf der Seite der Sammelkammer 4 die Pumpe 5 direkt über den Stutzen 7 an der in der Verankerungs- oder Aufstelleinrichtung 2 gelagerten Druckleitung 3 befestigt werden. Weitere Installationen zur Aufhängung der Pumpe 5 in der Sammelkammer 4 sind daher nicht erforderlich, so daß der Zugang zum Pumpensumpf und dessen Reinigung durch weitere Installationen nicht behindert wird. Bevorzugt weicht die Form des Schachts 1 im Bereich der Durchführung 8 von der Kugelform ab, bzw. der Pumpensumpf ist so gestaltet, daß eine freihängende Unterwasserkupplung für die Pumpe geschaffen wird.The pump 5 can also be coupled directly to the anchoring or positioning device 2, which preferably consists of concrete or polyurethane (PU) foam. For this purpose, at least part of the pressure line 3 for the pump is embedded in the anchoring or setting-up device 2 and introduced at a lower area via a pipe duct 8 in the shaft wall into the collecting chamber 4 at a suitable location. In the region of the bushing 8, the pump 5 can then be fastened directly on the side of the collecting chamber 4 directly via the connecting piece 7 to the pressure line 3 mounted in the anchoring or setting device 2. Further installations for suspending the pump 5 in the collection chamber 4 are therefore not required, so that the access to the pump sump and its cleaning is not hindered by further installations. Preferably, the shape of the shaft 1 deviates in the region of the passage 8 from the spherical shape, or the pump sump is designed so that a free-hanging underwater coupling is provided for the pump.

Alternativ kann vorgesehen sein, daß ein Teil der Druckleitung 3 durch den Schacht 1 geführt wird, um dort etwa Armaturen im Schacht vorzusehen. Der Verlauf ist als Druckleitung 3' entsprechend mit gestrichelten Linien gekennzeichnet. Hierzu weist der Schacht zwei weitere Durchführungen 8' und 8" für die Druckleitung 3' auf.Alternatively it can be provided that a part of the pressure line 3 is passed through the shaft 1 to provide there about fittings in the shaft. The course is as a pressure line 3 'according to dashed lines characterized. For this purpose, the shaft has two further passages 8 'and 8 "for the pressure line 3'.

Zur Transporterleichterung kann die Verankerungs- oder Aufstelleinrichtung Aussparungen für Transportgabeln von Flurförderfahrzeugen enthalten. So kann der erfindungsgemäße Schacht selbst mit kleineren Transportgeräten transportiert werden, schweres Räumgerät ist nicht erforderlich. To facilitate transport, the anchoring or setting-up device may contain recesses for transport forks of industrial trucks. Thus, the shaft according to the invention can be transported even with smaller transport equipment, heavy clearing equipment is not required.
