Description

Die Erfindung betrifft eine Schachtanordnung gemäß dem Oberbegriff des unabhängigen Patentanspruchs. Insbesondere betrifft die Erfindung eine selbstnivellierende Schachtanordnung mit verlaufender Deck- bzw. Tragschichteinbindung. Schachtanordnungen sind in unterschiedlichen Ausführungsformen bekannt und publiziert. Herkömmliche Schachtanordnungen umfassen einen Schacht, der meist aus mehreren Schachtringen zusammengesetzt ist und einen vertikal verlaufenden Zugang zu einem unterirdischen Objektes ermöglicht. Als Beispiel kann ein in einer Straße vorgesehener Schacht zum Zugang zu einem Kanal genannt werden, wobei der Schacht durch eine Schachtabdeckung abgedeckt ist.The invention relates to a shaft arrangement according to the preamble of the independent patent claim. In particular, the invention relates to a self-levelling manhole arrangement with running cover or base course integration. Shaft arrangements are known and published in various embodiments. Conventional manhole arrangements include a manhole, which is usually composed of several manhole rings and allows access to an underground object running vertically. A manhole provided in a street for access to a sewer can be mentioned as an example, the manhole being covered by a manhole cover.

Die internationale Anmeldung WO 8204276 A1 offenbart eine Konstruktion, bei der ein schildförmiges Stützelement beweglich gegenüber einem rohrförmigen Abschnitt einer Schachtabdeckung angeordnet ist. EP 0278 325 A1 zeigt einen Rahmen für eine Schachtabdeckung, mit einem ringförmigen Fortsatz, der in die gebundene Deckschicht eingegossen ist. Die Druckschriften DE 29708650 U1 , NL 6502680 und GB 2007286 A2 zeigen weitere Konstruktionen zur Halterung einer Schachtabdeckung.The international registration WO 8204276 A1 discloses a construction in which a shield-shaped support member is movably mounted relative to a tubular portion of a manhole cover. EP 0278 325 A1 shows a frame for a manhole cover with an annular extension cast into the bonded facing. The pamphlets DE 29708650 U1 , NL 6502680 and GB2007286A2 show other constructions for holding a manhole cover.

In der Regel werden die Schachtabdeckungen bündig mit der umliegenden Oberfläche eingebaut. Jedoch tritt bei herkömmlichen Schachtanordnungen in der Praxis das Problem auf, dass es durch Relativbewegungen, beispielsweise hervorgerufen durch das Befahren der Straße oder durch thermische Spannungen, Setzungen, etc., zu einem Versatz der Schachtabdeckung gegenüber der umliegenden Oberfläche kommt. Gegebenenfalls tritt eine Schrägstellung der Schachtabdeckung oder ein Einsinken der Schachtabdeckung auf oder die Schachtabdeckung überragt die umliegende Oberfläche.As a rule, the manhole covers are installed flush with the surrounding surface. However, in practice, the problem arises with conventional shaft arrangements that relative movements, for example caused by driving on the road or by thermal stresses, settlements, etc offset of the manhole cover from the surrounding surface. Eventually, the manhole cover will tilt or subside, or the manhole cover will overhang the surrounding surface.

Eine übliche Konstruktion zur Verringerung dieses Effektes ist ein waagrecht verlaufender Ring, der vor der Montage der Schachtabdeckung auf die ungebundene Tragschicht aufgelegt wird. Dieser Ring ist meist aus Stahl gefertigt und dient als Auflager für die Schachtabdeckung. Der Ring wird in weiterer Folge von oben durch die gebundene Deckschicht abgedeckt, sodass er sich waagrecht zwischen der gebundenen Deckschicht und der ungebundenen Tragschicht eingebunden wird.A common construction to reduce this effect is a horizontal ring that is placed on the unbound base course before the manhole cover is installed. This ring is usually made of steel and serves as a support for the manhole cover. The ring is then covered from above by the bound top layer so that it is bound horizontally between the bound top layer and the unbound base layer.

Als gebundene Deckschicht wird insbesondere eine Schicht bzw. ein Schichtaufbau bezeichnet, die als gebundene Tragschicht, als bituminös gebundene Tragschicht und/oder Asphaltschicht ausgebildet ist oder wirkt. Die Deckschicht kann aber auch eine Pflasterschicht oder Betonschicht umfassen oder sein.In particular, a layer or a layer structure is referred to as a bonded top layer, which is designed or acts as a bonded base layer, as a bituminous bonded base layer and/or asphalt layer. However, the covering layer can also comprise or be a plaster layer or concrete layer.

In der Praxis hat sich jedoch herausgestellt, dass sich die gebundene Deckschicht bei dieser Konstruktion im Bereich der Außenkante des Rings verformt und gegebenenfalls bricht, womit das Problem der Relativbewegung im Grunde genommen nur von der Schachtabdeckung in einen weiter außen liegenden Bereich verlagert, aber nicht gelöst wird.In practice, however, it has been found that with this construction the bonded cover layer deforms and possibly breaks in the area of the outer edge of the ring, which basically only shifts the problem of relative movement from the manhole cover to an area further out, but does not solve it becomes.

Aufgabe der Erfindung ist es nun, die Probleme des Standes der Technik zu überwinden und insbesondere eine Schachtanordnung zu schaffen, bei der die Schachtabdeckung in einer vorbestimmten Lage und insbesondere flächenbündig zur Oberfläche der Deckschicht angeordnet ist und über lange Stehzeiten angeordnet bleibt.The object of the invention is now to overcome the problems of the prior art and in particular to create a manhole arrangement in which the manhole cover is arranged in a predetermined position and in particular flush with the surface of the cover layer and remains in place for long periods of time.

Die erfindungsgemäße Aufgabe wird insbesondere durch die Merkmale des unabhängigen Patentanspruchs gelöst.The object according to the invention is achieved in particular by the features of the independent patent claim.

Gegebenenfalls ist vorgesehen, dass die Schachtabdeckung einen entfernbar oder bewegbar angeordneten Schachtdeckel und gegebenenfalls einen als Auflager für den Schachtdeckel wirkenden Schachtrahmen umfasst.If necessary, it is provided that the manhole cover comprises a manhole cover which is arranged in a removable or movable manner and if necessary a manhole frame which acts as a support for the manhole cover.

Alternativ ist vorgesehen, dass die Schachtabdeckung einen fixen, nicht entfernbaren Schachtdeckel umfasst.Alternatively, it is provided that the manhole cover includes a fixed, non-removable manhole cover.

Gegebenenfalls ist vorgesehen, dass die gebundene Deckschicht mindestens eine bituminös gebundene Schicht und bevorzugt eine obenliegende Asphaltschicht, eine Pflasterschicht oder eine Betonschicht umfasst.Optionally, it is provided that the bonded surface layer comprises at least one layer bonded with bitumen and preferably an overlying layer of asphalt, a layer of plaster or a layer of concrete.

Gegebenenfalls ist vorgesehen, dass die ungebundene Tragschicht einen, bevorzugt verfestigten, Schotterunterbau umfasst.If necessary, it is provided that the unbound base layer comprises a preferably consolidated gravel substructure.

Insbesondere betrifft die Erfindung eine selbstnivellierende Schachtanordnung mit verlaufender Tragschichteinbindung.In particular, the invention relates to a self-levelling manhole arrangement with a running base layer integration.

Die Schachtanordnung umfasst eine Stützvorrichtung. An dieser Stützvorrichtung ist die Schachtabdeckung angebracht oder aufgelagert. Die Schachtabdeckung kann direkt an oder auf der Stützvorrichtung angebracht sein oder es können zwischen der Schachtabdeckung und der Stützvorrichtung weitere Elemente, wie beispielsweise eine Mörtelschicht, eine Dichtschicht oder ähnliches, angeordnet sein. In bevorzugter Weise liegt die Schachtabdeckung also direkt oder indirekt auf der Stützvorrichtung auf und stützt sich insbesondere an der Stützvorrichtung ab.The well assembly includes a support device. The manhole cover is attached or supported on this support device. The manhole cover can be attached directly to or on the support device, or other elements, such as a layer of mortar, a sealing layer or the like, can be arranged between the manhole cover and the support device. In a preferred manner, the manhole cover therefore rests directly or indirectly on the support device and is supported in particular on the support device.

Die Stützvorrichtung ist unterhalb der gebundenen Deckschicht angeordnet. Gemäß einer Ausführungsform liegt die gebundene Deckschicht zumindest abschnittsweise oder vollständig auf der obenliegenden Fläche des mindestens einen Stützfortsatzes der Stützvorrichtung auf. Gemäß einer weiteren Ausführungsform ragt der Stützfortsatz derart in die ungebundene Tragschicht, dass zumindest dessen Außenbereich oder der gesamte Stützfortsatz oben und unten mit dem Material der ungebundenen Tragschicht umgeben ist.The support device is positioned below the bonded facing. According to one embodiment, the bonded cover layer lies at least partially or completely on the top surface of the at least one support extension of the support device. According to a further embodiment, the support extension protrudes into the unbound base layer in such a way that at least its outer area or the entire support extension is surrounded at the top and bottom by the material of the unbound base layer.

Die Stützvorrichtung weist einen gewissen Abstand zum Schacht, insbesondere zur Oberkante des Schachtes auf, wodurch der Schacht und die Stützvorrichtung im Wesentlichen voneinander entkoppelt sind. So übertragen sich Relativbewegungen der Schachtabdeckung und der Stützvorrichtung bevorzugt nicht auf den Schacht und auch Bewegungen des Schachtes übertragen sich nicht auf die Stützvorrichtung und die Schachtabdeckung. Hierzu ist bevorzugt zwischen der Stützvorrichtung und dem Schacht eine Fuge angeordnet. Diese Fuge kann gegebenenfalls durch eine Schürze oder durch ein elastisches Element, wie beispielsweise eine Dichtung, abgedeckt bzw. abgedichtet sein. Dieses elastische Element bzw. diese Schürze ist jedoch derart ausgestaltet, dass die Entkoppelung des Schachtes von der Stützvorrichtung erhalten bleibt.The support device is at a certain distance from the shaft, in particular from the upper edge of the shaft, as a result of which the shaft and the support device are essentially decoupled from one another. Thus, relative movements of the manhole cover and the support device are preferably not transferred to the manhole and movements of the manhole are also not transferred to the support device and the manhole cover. For this purpose, a joint is preferably arranged between the support device and the shaft. This joint can optionally be covered or sealed by an apron or by an elastic element such as a seal. However, this elastic element or this apron is designed in such a way that the decoupling of the shaft from the support device is maintained.

Die Stützverrichtung weist mindestens einen Stützfortsatz auf, der sich beispielsweise in radialer Richtung nach außen erstreckt. Der Stützfortsatz überragt somit die Schachtabdeckung in seitlicher Richtung. Der Stützfortsatz verläuft unterhalb der Deckschicht, sodass er in seiner bestimmungsgemäßen Einbaulage von außen bzw. oben nicht sichtbar ist. Bevorzugt erstreckt sich nur die Schachtabdeckung bis an die Oberfläche, sodass von außen/oben auch ausschließlich die Schachtabdeckung sichtbar ist.The support device has at least one support extension, which extends outwards in the radial direction, for example. The support extension thus projects beyond the manhole cover in the lateral direction. The support extension runs below the cover layer so that it is not visible from the outside or from above in its intended installation position. Preferably, only the manhole cover extends to the surface, so that only the manhole cover is visible from the outside/above.

Der Stützfortsatz dient der Verankerung und Abstützung der Stützvorrichtung und damit auch der Schachtabdeckung im oder am Untergrund. Diese Verankerung ist jedoch derart ausgebildet, dass sich die Schachtabdeckung bei Hebungen oder Senkungen der gebundenen Deckschicht mitbewegen kann, ohne dabei eine starke lokale Verformung der Deckschicht zu bewirken. Dies wird insbesondere durch den speziellen Verlauf und die spezielle Ausgestaltung des Stützfortsatzes ermöglicht.The support extension serves to anchor and support the support device and thus also the manhole cover in or on the ground. However, this anchoring is designed in such a way that the manhole cover can move with the bonded cover layer when it is raised or lowered, without severe local deformation to effect the top layer. This is made possible in particular by the special course and the special design of the support extension.

Erfindungsgemäß ist vorgesehen, dass der Stützfortsatz im Außenbereich tieferliegend angeordnet ist als im Innenbereich. Insbesondere verläuft die obenliegende Fläche des mindestens einen Stützfortsatzes von innen nach außen schräg nach unten. Hierdurch erhöht sich der Abstand der obenliegenden Fläche des Stützfortsatzes von der Oberfläche der Deckschicht in radialer Richtung. Durch diesen schrägen Verlauf kann auch der Verlauf des Einflusses von Relativbewegungen auf die Deckschicht beeinflusst werden. Dieser Verlauf bewirkt somit eine verlaufende Änderung der Steifigkeit von innen nach außen. Auch eine verlaufende Veränderung der Elastizität jenes Materials, das zwischen der Stützvorrichtung und der Oberfläche der Deckschicht angeordnet ist, kann dadurch bewirkt werden. Insbesondere durch die Vermeidung abrupter Steifigkeitsänderungen entlang des Verlaufs der Stützvorrichtung kann die erfindungsgemäße Aufgabe gelöst werden.According to the invention it is provided that the support extension is arranged lower in the outer area than in the inner area. In particular, the upper surface of the at least one support extension runs obliquely downwards from the inside to the outside. This increases the distance between the upper surface of the support extension and the surface of the cover layer in the radial direction. The course of the influence of relative movements on the cover layer can also be influenced by this oblique course. This progression thus causes a progressive change in rigidity from the inside to the outside. A running change in the elasticity of that material which is arranged between the support device and the surface of the cover layer can also be brought about in this way. The object according to the invention can be achieved in particular by avoiding abrupt changes in rigidity along the course of the support device.

Gegebenenfalls ist vorgesehen, dass die oben liegende Fläche des Stützfortsatzes der Schachtabdeckung schräg von dem Innenbereich Richtung Außenbereich verläuft. Die oben liegende Fläche weist bevorzugt einen Winkel von 5° bis 20°, insbesondere zwischen 8° und 12°, auf.If necessary, it is provided that the upper surface of the support extension of the manhole cover runs obliquely from the inner area towards the outer area. The upper surface preferably has an angle of 5° to 20°, in particular between 8° and 12°.

In bevorzugter Weise ist mindestens ein Stützfortsatz vorgesehen. Dieser Stützfortsatz kann beispielsweise ringförmig mit einer kegeligen obenliegenden Fläche ausgebildet sein. Jedoch kann ein derartiger ringförmig ausgebildeter Stützfortsatz auch an mehreren Stellen unterbrochen oder durchbrochen sei. Insbesondere können sich dadurch mehrere Stützfortsätze ergeben, die seitlich auskragen und in die ungebundene Tragschicht ragen. Beispielsweise können zwei Stützfortsätze an gegenüberliegenden Seiten auskragen oder es können mehrere Stützfortsätze sternförmig angeordnet sein.At least one support extension is preferably provided. This support extension can, for example, be ring-shaped with a conical upper surface. However, such a ring-shaped supporting extension can also be interrupted or perforated at several points. In particular, this can result in several supporting extensions that protrude laterally and protrude into the unbound base layer. For example, two support extensions can protrude on opposite sides or several support extensions can be arranged in a star shape.

In vorteilhafter Weise verläuft die oben liegende Fläche des Stützfortsatzes im Wesentlichen stetig, beispielsweise als schräge oder gekrümmte Fläche. Stufen, Absätze oder Freistellungen können vorgesehen sein, solange diese Unstetigkeiten nicht auf die Oberfläche der Deckschicht wirken. So wird durch das zwischen der Oberfläche der Deckschicht und der umliegenden Fläche des Stützfortsatzes angeordnete Material eine Verteilung der Kräfte und somit eine Glättung des Steifigkeitsverlaufs bzw. des Elastizitätsverlaufs bewirkt.Advantageously, the upper surface of the support extension runs essentially continuously, for example as a sloping or curved surface. Steps, paragraphs or waivers can be provided as long as these discontinuities not act on the surface of the top layer. The material arranged between the surface of the cover layer and the surrounding surface of the supporting extension thus causes a distribution of the forces and thus a smoothing of the stiffness profile or the elasticity profile.

Gegebenenfalls ist vorgesehen, dass die Schürze einen Kragen aufweist, der im Wesentlichen ringförmig oder laschenförmig ausgebildet ist und zwischen der Schachtabdeckung und der Stützvorrichtung eingeklemmt ist. Durch diese Einklemmung des Kragens kann die Schürze in ihrer Position gehalten werden. Hierbei erstreckt sich die Schürze von der Stützvorrichtung nach unten und überragt dabei die Fuge, sodass diese abgedeckt ist. Die Schürze kann hierfür beispielsweise abschnittsweise zylinderförmig ausgebildet sein. Alternativ kann der Kragen der Schürze aber auch ohne Einklemmung an der Stützvorrichtung oder einer hierfür vorgesehen Schulter aufliegen.If necessary, it is provided that the apron has a collar which is essentially ring-shaped or strap-shaped and is clamped between the manhole cover and the support device. This pinching of the collar allows the apron to be held in place. In this case, the apron extends downwards from the support device and protrudes beyond the joint so that it is covered. For this purpose, the apron can be configured in sections, for example, in the shape of a cylinder. Alternatively, the collar of the apron can also rest on the support device or on a shoulder provided for this purpose without being pinched.

Fig. 1 zeigt eine schematische Schnittansicht, wobei die Schnittebene im Wesentlichen vertikal verläuft. Grundsätzlich kann gemäß einer nicht dargestellten Ausführungsform der Schacht auch schräg verlaufen. 1 shows a schematic sectional view, with the sectional plane running essentially vertically. In principle, according to an embodiment that is not shown, the shaft can also run at an angle.

Die Schachtanordnung ragt bzw. verläuft durch eine ungebundene Tragschicht 1 und durch eine gebundene Deckschicht 2. Die Tragschicht 1 kann in allen Ausführungsformen Erdreich und/oder Schotter sein, das bevorzugt durch herkömmliche Maßnahmen wie Rütteln verfestigt ist. Die Deckschicht 2 ist als gebundene Deckschicht 2, insbesondere als bituminös gebundene Deckschicht 2, ausgebildet. Im Falle eines Straßenaufbaus umfasst die gebundene Deckschicht 2 bevorzugt auch eine Asphaltschicht 21.The shaft arrangement protrudes or runs through an unbound base layer 1 and through a bound cover layer 2. In all embodiments, the base layer 1 can be soil and/or gravel, which is preferably consolidated by conventional measures such as shaking. The top layer 2 is designed as a bonded top layer 2, in particular as a bituminous bonded top layer 2. In the case of a road structure, the bound surface layer 2 preferably also comprises an asphalt layer 21.

Die Deckschicht 2 weist eine Oberfläche 7 auf, die außen liegend angeordnet ist und beispielsweise als Fahr- oder Gehweg dient. Die Schachtanordnung umfasst eine Schachtabdeckung 6. Diese Schachtabdeckung 6 ist im vorliegenden Fall derart angeordnet, dass der Schachtdeckel 19 der Schachtabdeckung 6 im Wesentlichen flächenbündig an die Oberfläche 7 der Deckschicht 2 anschließt, oder dass der Schachtdeckel 19 der Schachtabdeckung 6 im Wesentlichen flächenbündig mit der Oberfläche 7 der Deckschicht 2 angeordnet ist und insbesondere mit der Oberfläche 7 der Deckschicht 2 in einer Ebene liegt.The cover layer 2 has a surface 7 which is arranged on the outside and is used, for example, as a driveway or sidewalk. The manhole arrangement comprises a manhole cover 6. In the present case, this manhole cover 6 is arranged in such a way that the manhole cover 19 of the manhole cover 6 is essentially flush with the surface 7 of the cover layer 2, or that the manhole cover 19 of the manhole cover 6 is essentially flush with the surface 7 of the cover layer 2 is arranged and in particular lies in one plane with the surface 7 of the cover layer 2 .

Um diese gewünschte Positionierung der Schachtabdeckung 6 gegenüber der Deckschicht 2 auch über längere Zeit oder dauerhaft beizubehalten, ist die Schachtabdeckung 6 auf einer Stützvorrichtung 4 abgestützt. Die Stützvorrichtung 4 weist hierzu eine Stützfläche 8 auf, an der die Schachtabdeckung 6 abgestützt bzw. angebracht ist.In order to maintain this desired positioning of the manhole cover 6 relative to the cover layer 2 over a long period of time or permanently, the manhole cover 6 is supported on a support device 4 . For this purpose, the support device 4 has a support surface 8 on which the manhole cover 6 is supported or attached.

Zudem umfasst die Stützvorrichtung 4 zumindest einen Stützfortsatz 9. In der vorliegenden Ausführungsform ist der Stützfortsatz 9 ringförmig ausgebildet und erstreckt sich um den durch die Schachtanordnung gebildeten Hohlraum. Der Stützfortsatz 9 der Stützvorrichtung 4 umfasst eine oben liegende Fläche 10. Dies ist jene Fläche, die in der bestimmungsgemäßen Einbaulage nach oben weist. Diese oben liegende Fläche 10 ist in der vorliegenden Ausführungsform derart geneigt, dass sie im Außenbereich 11 des Stützfortsatzes 9 einen größeren Abstand zur Oberfläche 7 aufweist als im Innenbereich 13 des Stützfortsatzes 9.In addition, the support device 4 comprises at least one support extension 9. In the present embodiment, the support extension 9 is ring-shaped and extends around the cavity formed by the shaft arrangement. The support extension 9 of the support device 4 includes an overhead surface 10. This is the surface that faces upwards in the intended installation position. In the present embodiment, this upper surface 10 is inclined in such a way that it is at a greater distance from the surface 7 in the outer area 11 of the support extension 9 than in the inner area 13 of the support extension 9.

Insbesondere kann in allen Ausführungsformen der Stützfortsatz 9 keilförmig ausgebildet sein oder zumindest ausgehend vom Innenbereich 13 schräg nach unten Richtung Außenbereich 11 verlaufen. Durch der Ausgestaltung der Fig. 1 liegt die oben liegende Fläche 10 des Stützfortsatzes 9 im Außenbereich 11 und insbesondere im Bereich der Spitze 12 des Stützfortsatzes 9 tiefer als im Innenbereich 13. Bei der Ausgestaltung der Fig. 1 wird dadurch eine kegelige Fläche gebildet.In particular, in all embodiments, the support extension 9 can be wedge-shaped or at least run obliquely downwards, starting from the inner area 13 , in the direction of the outer area 11 . By designing the 1 is the overhead surface 10 of the support extension 9 in the outer area 11 and in particular in the area of the tip 12 of the support extension 9 lower than in the inner area 13. In the design of the 1 This creates a conical surface.

In der vorliegenden Ausführungsform ragt der Stützfortsatz 9 der Stützvorrichtung 4 in die ungebundene Tragschicht 1. Insbesondere ist in der bestimmungsgemäßen Einbaulage oberhalb und unterhalb des Stützfortsatzes 9 das Material der ungebundenen Tragschicht 1 angeordnet.In the present embodiment, the support extension 9 of the support device 4 protrudes into the unbound base layer 1. In particular, in the intended installation position, the material of the unbound base layer 1 is arranged above and below the support extension 9.

Zur Entkoppelung der Schachtabdeckung 6 vom Schacht 3 ist zwischen dem Schacht 3 und der Schachtabdeckung 6 eine Fuge 5 vorgesehen bzw. freigehalten. Diese Fuge 5 ermöglicht eine Relativbewegung der Schachtabdeckung 6 gegenüber dem Schacht 3, insbesondere eine Relativbewegung der Stützvorrichtung 4 gegenüber dem Schacht 3. Dadurch ist eine Relativbewegung in vertikaler Richtung ermöglicht. Zum Abdecken bzw. zur Abdichtung der Fuge 5 ist in der vorliegenden Ausführungsform eine Schürze 15 vorgesehen.To decouple the manhole cover 6 from the manhole 3 , a joint 5 is provided or kept free between the manhole 3 and the manhole cover 6 . This joint 5 enables a relative movement of the manhole cover 6 with respect to the manhole 3, in particular a relative movement of the support device 4 with respect to the manhole 3. This enables a relative movement in the vertical direction. In the present embodiment, an apron 15 is provided to cover or seal the joint 5 .

Die Fuge 5 ist insbesondere zwischen der Oberkante 14 des Schachtes 3 und der Stützvorrichtung 4 freigehalten. Der Schacht 3 kann herkömmlich aufgebaut sein und umfasst einen Schachtmantel 17, der beispielsweise durch mehrere Schachtringe gebildet ist. Überdies umfasst der Schacht 3 einen Schachthals 18, der sich Richtung Schachtabdeckung 6 nach oben hin verjüngt. Die Schachtabdeckung 6 umfasst in der vorliegenden Ausführungsform einen öffenbaren Schachtdeckel 19 und einen Schachtrahmen 20.The joint 5 is kept free in particular between the top edge 14 of the shaft 3 and the support device 4 . The shaft 3 can have a conventional design and includes a shaft casing 17 which is formed, for example, by a number of shaft rings. In addition, the shaft 3 includes a shaft neck 18 which tapers in the direction of the shaft cover 6 towards the top. In the present embodiment, the manhole cover 6 comprises an openable manhole cover 19 and a manhole frame 20.

Der Schachtdeckel 19 kann in herkömmlicher Weise als geschlossener Deckel oder als Deckel mit Öffnungen, beispielsweise als Gitterabdeckung, ausgebildet sein. Der Schachtrahmen 20 ist in der vorliegenden Ausführungsform an der Stützvorrichtung 4 und insbesondere an dessen Stützfläche 8 abgestützt. Grundsätzlich ist aber auch denkbar, dass sich der Schachtdeckel 19 direkt an einer Stützfläche 8 der Stützvorrichtung 4 abstützt.The manhole cover 19 can be designed in a conventional manner as a closed cover or as a cover with openings, for example as a grid cover. In the present embodiment, the manhole frame 20 is supported on the support device 4 and in particular on its support surface 8 . But it is also fundamental conceivable that the manhole cover 19 is supported directly on a support surface 8 of the support device 4.

Fig. 2 zeigt eine weitere Ausführungsform einer möglichen erfindungsgemäßen Schachtanordnung. Die mit Bezugszeichen versehenen Elemente entsprechen mit folgenden Ausnahmen den Elementen aus Fig. 1. 2 shows a further embodiment of a possible shaft arrangement according to the invention. The elements provided with reference symbols correspond to the elements in FIG 1 .

Im Unterschied zur Ausführungsform der Fig. 1 ist in Fig. 2 zur Abdeckung bzw. Abdichtung der Fuge 5 statt einer Schürze 15 ein elastisches Element 16 angeordnet. Dieses elastische Element 16 ist insbesondere derart elastisch ausgestaltet, dass eine Entkoppelung der Schachtabdeckung 6 und der Stützvorrichtung 4 gegenüber dem Schacht 3 erhalten bleibt. Alternativ oder zusätzlich kann aber auch in dieser Ausführungsform eine Schürze wie in Fig. 1 vorgesehen sein.In contrast to the embodiment of 1 is in 2 to cover or seal the joint 5 instead of an apron 15, an elastic element 16 is arranged. This elastic element 16 is in particular designed to be elastic in such a way that a decoupling of the manhole cover 6 and the support device 4 from the manhole 3 is maintained. Alternatively or additionally, an apron as in 1 be provided.

Zudem ist im Unterschied zur Ausführungsform der Fig. 1 der Stützfortsatz 9, insbesondere dessen oben liegende Fläche 10, zumindest teilweise direkt mit der gebundenen Deckschicht 2 in Kontakt. Dennoch ragt der Stützfortsatz 9, insbesondere in seinem Außenbereich 11 bzw. mit seiner Spitze 12 in die ungebundene Tragschicht 1, sodass oberhalb und unterhalb der Spitze 12 des Stützfortsatzes 9 das Material der ungebundenen Tragschicht 1 angeordnet ist. Im Innenbereich 13 des Stützfortsatzes 9 der Stützvorrichtung 4 liegt jedoch die gebundene Deckschicht 2 direkt an der oben liegende Fläche 10 des Stützfortsatzes 9 an.In addition, in contrast to the embodiment of 1 the support extension 9, in particular its upper surface 10, is at least partially in direct contact with the bonded cover layer 2. Nevertheless, the support extension 9 protrudes, in particular in its outer area 11 or with its tip 12 into the unbound base layer 1, so that the material of the unbound base layer 1 is arranged above and below the tip 12 of the support extension 9. In the inner region 13 of the support extension 9 of the support device 4, however, the bonded cover layer 2 lies directly on the upper surface 10 of the support extension 9.

Gemäß einer weiteren, nicht dargestellten Ausführungsform der Erfindung ist die gesamte oben liegende Fläche 10 des Stützfortsatzes 9 der Stützvorrichtung 4 direkt mit der gebundenen Deckschicht 2 in Kontakt, womit der Stützfortsatz 9 nur an seiner Unterseite bzw. gegebenenfalls an seiner Außenseite mit der ungebundenen Tragschicht 1 in Kontakt steht. Auch in dieser Ausführungsform ist die oben liegende Fläche 10 im Außenbereich 11 bzw. im Bereich der Spitze 12 tieferliegend angeordnet als im Innenbereich 13. Insbesondere kann auch bei dieser nicht dargestellten Ausführungsform die oben liegende Fläche 10 des Stützfortsatzes 9 von innen nach außen schräg nach unten verlaufen. Die restlichen Komponenten dieser Ausführungsform können den Komponenten der Fig. 1 oder 2 entsprechen.According to a further embodiment of the invention, not shown, the entire upper surface 10 of the support extension 9 of the support device 4 is in direct contact with the bound cover layer 2, so that the support extension 9 is only on its underside or possibly on its outside with the unbound base layer 1 is in contact. In this embodiment, too, the upper surface 10 in the outer area 11 or in the area of the tip 12 is arranged lower than in the inner area 13. In particular, in this embodiment, which is not shown, the upper surface 10 of the support extension 9 can be inclined downwards from the inside to the outside get lost. The remaining components of this embodiment can the components of 1 or 2 are equivalent to.
