Abstract

The upper and lower edges (18,20) are so formed in relation to each other, that in the superimposed state in the peripheral direction location surfaces (28) displaced relatively to one another are formed. One of the edges (18) has several stages equally spaced, in a peripheral direction, between which raised location surfaces are formed. Whilst the other edge (20), at all points of the periphery, has identical radial cross-sections. The lower edge has an inner throat (22), and the upper edge has a complementary radial cross-section, whereby in the superimposed state a hollow space is formed between both edges to accommodate a seal (26).

Description

Die Erfindung betrifft ein Schachtbauteil mit den weiteren Merkmalen des Oberbegriffs des Anspruchs 1 sowie ein Verfahren zu seiner Herstellung.The invention relates to a shaft component with the further features of the preamble of claim 1 and a method for its production.

Kanalisationsschächte und ähnliche Tiefbauwerke werden üblicherweise hergestellt, indem zunächst eine Grube ausgehoben wird, in der Grube im wesentlichen ringförmige vorgefertigte Schachtbauteile aus Beton oder Stahlbeton aufeinander gesetzt werden und die Grube sodann so weit wieder aufgefüllt wird, daß das Erdreich an der Außenwandung der aufeinander gesetzten Schachtbauteile anliegt.Sewer shafts and similar civil engineering structures are usually made by first excavating a pit, placing essentially ring-shaped prefabricated shaft components made of concrete or reinforced concrete on top of one another and then refilling the pit to such an extent that the soil on the outer wall of the stacked shaft components is present.

Die einzelnen Schachtbauteile sind dabei mit oberen und unteren Rändern versehen, die komplementär zueinander ausgebildet sind, so daß eine konzentrische Ausrichtung der Schachtringe erzwungen wird. Die Kraftübertragung des Eigengewichts der aus Schachtbauteilen bestehenden Säule an den Fugen zwischen den einzelnen, aufeinander gesetzten Schachtringen erfolgt gemäß dem Stand der Technik über eine zwischengeschaltete Mörtelschicht zum Ausgleich von Maßtoleranzen. Die Einbringung des Mörtels in die kreisringförmige Fuge zwischen zwei aufeinander gesetzten Schachtringen bereitet auf der Baustelle nicht nur vom Arbeitsablauf her Schwierigkeiten, sondern durch einen ungleichmäßigen Mörtelauftrag können sich auch ungünstige Auswirkungen auf die Wasserdichtheit und Standsicherheit des fertigen Schachts ergeben. Insbesondere das notwendige Dichtelement in Form eines zwischen den Rändern zweier aufeinander liegender Schachtringe eingelegten Gummirings wird bei herkömmlichen in der beschriebenen Fertigbauweise hergestellten Schächten oft undicht, da es bei der Montage mit Mörtel verschmutzt wird o.ä. Insgesamt führen die undefinierten statischen Verhältnisse dazu, daß in den aus Beton oder Stahlbeton bestehenden Schachtringen Spannungen auftreten, für die diese nicht ausgelegt sind. Aus Kostengründen sind auch in Stahlbetonbauweise hergestellte Schachtringe lediglich mit einer sogenannten Transportsicherung versehen, nicht jedoch mit einer Bewehrung, die den durch die geschilderte undefinierte statische Belastung auftretenden Beanspruchungen gerecht wird.The individual shaft components are provided with upper and lower edges which are complementary to one another, so that a concentric alignment of the shaft rings is forced. The force transmission of the dead weight of the column consisting of shaft components at the joints between the individual, stacked shaft rings takes place according to the prior art via an interposed mortar layer to compensate for dimensional tolerances. The introduction of the mortar into the circular Joints between two stacked manhole rings not only cause difficulties on the construction site due to the workflow, but an uneven application of mortar can also have unfavorable effects on the watertightness and stability of the finished manhole. In particular, the necessary sealing element in the form of a rubber ring inserted between the edges of two stacked manhole rings often leaks in conventional manholes manufactured in the prefabricated construction described, since it is contaminated with mortar or the like during assembly. Overall, the undefined static conditions mean that stresses occur in the manhole rings made of concrete or reinforced concrete for which they are not designed. For cost reasons, manhole rings made of reinforced concrete are only provided with a so-called transport lock, but not with reinforcement that meets the stresses caused by the undefined static load described.

Bei aus herkömmlichen Schachtbauteilen bzw. Schachtringen gefertigten Schächten kommt es daher immer wieder zu Rissen und anderen Undichtigkeiten, die aus naheliegenden Gründen unbedingt zu vermeiden sind.In the case of manholes made from conventional manhole components or manhole rings, there are always cracks and other leaks which must be avoided for obvious reasons.

Der Erfindung liegt daher die Aufgabe zugrunde, bekannte Schachtbauteile kostengünstig so zu modifizieren, daß beim Aufeinandersetzen von Schachtbauteilen oder Schachtringen zu einem Schacht die oben erwähnten statischen Probleme entfallen.The invention is therefore based on the object of inexpensively modifying known shaft components so that when stacking shaft components or shaft rings to form a shaft, the above-mentioned static problems are eliminated.

Die Lösung der Aufgabe ist erfindungsgemäß dadurch gekennzeichnet, daß bei einem gattungsgemäßen Schachtbauteil oberer und unterer Rand in bezug aufeinander so geformt sind, daß im aufeinandergesetzten Zustand in Umfangsrichtung voneinander abgesetzte Auflagerflächen entstehen.The solution to the problem is characterized in that in a generic shaft component, the upper and lower edges are shaped with respect to one another in such a way that support surfaces are formed which are set apart from one another in the circumferential direction.

Insbesondere ist vorgesehen, daß drei Auflagerflächen in Umfangsrichtung gleichmäßig voneinander beabstandet ausgebildet werden, wobei diese vorzugsweise als Vorsprünge im jeweils unteren Rand eines Schachtbauteils ausgebildet sind. Mit anderen Worten ist zumindest einer der Ränder, vorzugsweise der untere, in Umfangsrichtung so ausgebildet, daß er mehrere gleichmäßig voneinander beabstandete Stufen aufweist, zwischen denen erhabene Auflagerflächen gebildet werden, während der jeweils andere Rand an allen Stellen des Umfangs denselben radialen Querschnitt aufweist, in dem insbesondere eine ringförmige Auflagerfläche integriert ist, auf der die vorzugsweise drei Vorsprünge des jeweils oberen Schachtbauteils aufstehen.In particular, it is provided that three support surfaces are formed evenly spaced apart from one another in the circumferential direction, these preferably being projections in the respective lower edge a shaft component are formed. In other words, at least one of the edges, preferably the lower, is formed in the circumferential direction in such a way that it has a plurality of steps which are evenly spaced from one another, between which raised bearing surfaces are formed, while the respective other edge has the same radial cross section at all points on the circumference which, in particular, integrates an annular bearing surface on which the preferably three projections of the respective upper shaft component stand.

Die erfindungsgemäßen Schachtbauteile lassen sich so übereinander stapeln bzw. so aufeinander setzen, daß die Lastübertragung des jeweils auf einem Schachtbauteil lastenden Gewichts sowie der Verkehrs- und Erdlasten der über ihm angeordneten Schachtbauteile in definierten Zonen erfolgt. Insbesondere bei drei Auflagerflächen kann es nicht zu einem Verkanten oder einem schiefen Aufsetzen der Schachtbauteile kommen, wodurch die einzubringende Mörtelschicht einfacher und wesentlich gleichmäßiger aufzubringen ist.The shaft components according to the invention can be stacked one above the other or placed on top of one another in such a way that the load transfer of the weight on each shaft component and the traffic and earth loads of the shaft components arranged above it takes place in defined zones. In particular with three bearing surfaces, the shaft components cannot be tilted or placed obliquely, as a result of which the mortar layer to be introduced is easier and considerably more uniform to apply.

Insbesondere bei schweren Schachtbauteilen ist insbesondere vorgesehen, daß die umfangsmäßig voneinander beabstandeten Auflagerflächen, vorzugsweise jeweils des unteren Randes, aus eingelegten Streifen aus einem elastischen Material, vorzugsweise einem Hartelastomer, bestehen, das während des Betonierens des Schachtbauteils in die entsprechende Form eingelegt worden ist.In the case of heavy manhole components in particular, it is provided in particular that the circumferentially spaced support surfaces, preferably each of the lower edge, consist of inserted strips of an elastic material, preferably a hard elastomer, which was inserted into the corresponding shape during concreting of the manhole component.

Vorzugsweise weisen die Schachtbauteile eine äußere Markierung auf, die es den schachtausführenden Bauarbeitern leichter macht, die Schachtbauteile in Umfangsrichtung so jeweils aufeinander auszurichten, daß die kraftübertragenden Auflagerflächen einer jeden Trennfuge jeweils senkrecht übereinander angeordnet sind.The shaft components preferably have an external marking which makes it easier for the shaft-executing construction workers to align the shaft components with one another in the circumferential direction in such a way that the force-transmitting bearing surfaces of each parting line are arranged vertically one above the other.

Das erfindungsgemäße Schachtbauteil ermöglicht die Herstellung von Schächten mit definierten statischen Verhältnissen, bei denen Risse der Wandung unter dem Wasserinnendruck oder dem Eigengewicht der Schachtbauteile oder der Verkehrs- und Erdlasten nicht mehr zu befürchten sind.The manhole component according to the invention makes it possible to manufacture manholes with defined static conditions in which cracks in the wall are no longer to be feared under the internal water pressure or the weight of the manhole components or the traffic and earth loads.

Ein Abwasserschacht 10 besteht aus mehreren Schachtringen 12A, 12B (und nicht mehr dargestellt) 12C usw., die oben durch ein sich verjüngendes Abschlußschachtteil 14 mit einem Kanaldeckel 16 abgeschlossen werden. Der Kanaldeckel 16 befindet sich beispielsweise auf Fahrbahnniveau einer Straße, während die dargestellten Schachtbauteile 14, 12A, 12B usw. im eingebauten Zustand im nicht dargestellten Erdreich liegen.A sewage shaft 10 consists of a plurality of manhole rings 12A, 12B (and no longer shown) 12C etc., which are closed at the top by a tapering manhole part 14 with a manhole cover 16. The manhole cover 16 is located, for example, at the level of a road, while the shaft components 14, 12A, 12B, etc. shown are in the installed state in the soil, not shown.

Jedes Schachtbauteil weist einen oberen Rand 18 und einen unteren Rand 20 auf. Oberer Rand 18 und unterer Rand 20 sind im wesentlichen rotationssymmetrisch ausgebildet und weisen solche radialen Querschnitte auf, daß jeweils ein Schachtbauteil 12A auf ein Schachtbauteil 12B aufgesetzt werden kann. Der jeweils untere Rand 20 weist eine innere umlaufende Kehle 22 auf, entsprechend jeder oberer Rand 18 eine äußere umlaufende Kehle 24, so daß die Querschnitte vom oberen Rand 18 und unterem Rand 20 eines jeden Schachtbauteils komplementär zueinander ausgestaltet sind und im zusammengesetzten Zustand zentrierend ineinander eingreifen. Zwischen den beiden Rändern wird ein Hohlraum gebildet, in dem eine Dichtung 26 angeordnet ist. Erfindungsgemäß ist vorgesehen, daß im unteren Rand 20 eines jeden Schachtbauteils drei Streifen 28 aus einem elastischen Material eingelegt sind, die - wie Figur 1 zeigt - rotationssymmetrisch gleichmäßig beabstandet angeordnet sind. Die drei eingelegten Streifen 28 bilden definierte Auflagerflächen 28, die auf der ringförmigen Auflagerfläche 30 des jeweils oberen Randes 18 in definierter Weise aufstehen.Each shaft component has an upper edge 18 and a lower edge 20. The upper edge 18 and lower edge 20 are essentially rotationally symmetrical and have radial cross sections such that a shaft component 12A can be placed onto a shaft component 12B. The respective lower edge 20 has an inner circumferential groove 22, corresponding to each upper edge 18 an outer circumferential groove 24, so that the cross sections of the upper edge 18 and lower edge 20 of each shaft component are complementary to one another and, when assembled, engage in a centering manner . A cavity is formed between the two edges, in which a seal 26 is arranged. According to the invention, three strips 28 made of an elastic material are inserted in the lower edge 20 of each shaft component, which - as in FIG. 1 shows - are arranged rotationally symmetrically evenly spaced. The three inserted strips 28 form defined support surfaces 28, which stand up in a defined manner on the annular support surface 30 of the respective upper edge 18.

Die Nachgiebigkeit der aus einem Elastomer bestehenden Auflagerflächen 28 zusammen mit den definierten statischen Verhältnissen sorgt für einen definierten Kraftfluß, der sicherstellt, daß die einzelnen Schachtbauteile trotz des Wasserinnendruckes und des Eigengewichtes oder eventueller Verkehrs- oder Erdlasten unbeschädigt bleiben.The resilience of the bearing surfaces 28 consisting of an elastomer together with the defined static conditions ensures a defined flow of force which ensures that the individual shaft components remain undamaged despite the internal water pressure and the dead weight or possible traffic or earth loads.
