Definitions
- the invention relates to drainage articles of all kinds, e.g. Sludge traps, heavy and light liquid separators, maintenance or sampling shafts, rainwater, yard or street drains and the like.
- Such drainage objects increasingly remove or absorb groundwater-endangering liquids.
- Manhole components that are used to adapt to the Surface level or to achieve a frost-free depth as an inspection shaft on the drainage objects must therefore be tightly connected with each other in the future, with the drainage object and the upper shaft end part.
- the US-PS 3,980,311 shows such a sealed shaft, which consists of a shaft bottom part, two shaft rings, a compensating ring and the upper shaft end part.
- the seal has the shape of a round profile or semicircular profile ring, which is inserted into a groove located on the upper component and bears against the mating surface on the lower shaft component.
- the surfaces delimiting the cavity for the sealing ring are inclined, so that the sealing ring is strongly deformed when the shaft component is placed on it and is subjected to shearing. The sealing rings are damaged and then no longer seal properly.
- Housing or chess floor parts often have rectangular cross sections, e.g. cast iron gasoline separators or yard drains.
- shaft components usually have circular cross sections.
- the housing (1) or shaft bottom part is pulled together on top of an opening with a circular cross-section, the Diameter of the opening exceeds the width of the housing (1) or shaft bottom part, that all contact surfaces (5) for the sealing rings are at least approximately vertical and flat, and that the outer surface (5) of the collar (2) surrounding the circular opening is the inner one Represents the bearing surface for the sealing ring (6).
- the sections of the underside of the next shaft component that exceed the width of the housing are provided to intercept and introduce the traffic load into the surrounding subsoil. These sections can be supported on foundations.
- the outer surface of the collar 2 is designed as a contact surface 5 for a sealing ring 6 which rolls into the position shown when the shaft component 7 is placed on it.
- the next shaft component 7 with the inner ring surface is supported on the top 8 of the collar 2.
- the spring 10 engages over the collar 2 and is supported there on a support structure (indicated by dash-dotted lines), for example a foundation 11, made of in-situ concrete.
- Fig. 3 shows the upper shaft end.
- the shaft end part consists of a frame 14 produced in a composite construction and a cover 16 inserted into the support 15.
- the frame has at the bottom an externally projecting spring 17, the inner surface of which forms the contact surface for the sealing ring 18.
- the counter surface is provided on the corresponding projection of the shaft construction part 19.

Description
Die Erfindung betrifft Entwässerungsgegenstände aller Art, wie z.B. Schlammfänge, Schwer- und Leichtflüssigkeitsabscheider, Wartungs- oder Probenahmeschächte, Regenwasser-, Hof- oder Straßenabläufe und dgl.. Derartige Entwässerungsgegenstände führen zunehmend grundwassergefährdende Flüssigkeiten ab oder nehmen sie auf. Es wird daher seit einiger Zeit die Forderung erhoben, diese Entwässerungsgegenstände bis an die Oberfläche absolut dicht auszubilden.The invention relates to drainage articles of all kinds, e.g. Sludge traps, heavy and light liquid separators, maintenance or sampling shafts, rainwater, yard or street drains and the like. Such drainage objects increasingly remove or absorb groundwater-endangering liquids. For some time now, there has been a demand to make these drainage objects absolutely tight to the surface.
Schachtaufbauteile, die zur Angleichung an das Oberflächenniveau oder zur Erreichung einer frostfreien Tiefe als Revisionsschacht auf die Entwässerungsgegenstände aufgesetzt werden, müssen deshalb in Zukunft untereinander, mit dem Entwässerungsgegenstand und dem oberen Schachtabschlußteil dicht verbunden sein.Manhole components that are used to adapt to the Surface level or to achieve a frost-free depth as an inspection shaft on the drainage objects must therefore be tightly connected with each other in the future, with the drainage object and the upper shaft end part.
Die US-PS 3,980,311 zeigt einen solchen abgedichteten Schacht, der aus einem Schachtbodenteil, zwei Schachtringen, einem Ausgleichring und dem oberen Schachtabschlußteil besteht. Die Dichtung hat die Form eines Rundprofil- oder Halbrundprofilringes, der jeweils in eine am oberen Bauteil befindliche Nut eingelegt ist und gegen die am unteren Schachtbauteil vorhandene Gegenfläche anliegt. Die den Hohlraum für den Dichtring begrenzenden Flächen verlaufen geneigt, so daß der Dichtring beim Aufsetzen des Schachtbauteils stark verformt und auf Abscheren beansprucht wird. Die Dichtringe werden beschädigt und dichten dann nicht mehr einwandfrei ab.The US-PS 3,980,311 shows such a sealed shaft, which consists of a shaft bottom part, two shaft rings, a compensating ring and the upper shaft end part. The seal has the shape of a round profile or semicircular profile ring, which is inserted into a groove located on the upper component and bears against the mating surface on the lower shaft component. The surfaces delimiting the cavity for the sealing ring are inclined, so that the sealing ring is strongly deformed when the shaft component is placed on it and is subjected to shearing. The sealing rings are damaged and then no longer seal properly.
Gehäuse oder Schachbodenteile haben häufig rechteckige Querschnitte, wie z.B. gußeiserne Benzinabscheider oder Hofabläufe. Schachtaufbauteile haben jedoch üblicherweise kreisrunde Querschnitte. Es bestand der Wunsch, für den dichten Anschluß des Schachtbauteils an das Gehäuse bzw. Schachtbodenteil eine leicht handhabbare und einfache Lösung zu finden.Housing or chess floor parts often have rectangular cross sections, e.g. cast iron gasoline separators or yard drains. However, shaft components usually have circular cross sections. There was a desire to find an easily manageable and simple solution for the tight connection of the manhole component to the housing or manhole base part.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Gehäuse (1) bzw. Schachtbodenteil oben auf eine Öffnung mit kreisförmigen Querschnitt zusammengezogen ist, wobei der Durchmesser der Öffnung die Breite des Gehäuses (1) bzw. Schachtbodenteils übertrifft, daß alle Anlagenflächen (5) für die Dichtringe mindestens annähernd vertikal verlaufen und eben sind, und daS die Außenfläche (5) des die kreisförmige Öffnung umgebenden Kragens (2) die innere Auflagefläche für den Dichtring (6) darstellt. Zum Abfangen und Einleiten der Verkehrslast in den umgebenden Untergrund sind die die Breite des Gehäuses übertreffenden Abschnitte der Unterseite des nächsten Schachtbauteils vorgesehen. Diese Abschnitte können auf Fundamenten abgestützt werden.This object is achieved in that the housing (1) or shaft bottom part is pulled together on top of an opening with a circular cross-section, the Diameter of the opening exceeds the width of the housing (1) or shaft bottom part, that all contact surfaces (5) for the sealing rings are at least approximately vertical and flat, and that the outer surface (5) of the collar (2) surrounding the circular opening is the inner one Represents the bearing surface for the sealing ring (6). The sections of the underside of the next shaft component that exceed the width of the housing are provided to intercept and introduce the traffic load into the surrounding subsoil. These sections can be supported on foundations.
Zusätzliche Bauteile, wie Adapter oder Übergangsplatten und -ringe erübrigen sich bei der erfindungsgemäßen Ausbildung der Verbindung. Der Zugang zu dem Entwässerungsgegenstand wird durch keinen Vorsprung oder Absatz behindert.Additional components, such as adapters or transition plates and rings, are unnecessary in the design of the connection according to the invention. Access to the drainage item is not hindered by any ledge or heel.

Die Außenfläche des Kragens 2 ist als Anlagefläche 5 für einen Dichtring 6 ausgebildet, der beim Aufsetzen des Schachtbauteils 7 in die dargestellte Lage rollt. Auf der Oberseite 8 des Kragens 2 stützt sich das nächste Schachtbauteil 7 mit der inneren Ringfläche ab. Die Feder 10 übergreift den Kragen 2 und stützt sich dort auf einer (strichpunktiert angedeuteten) Stützkonstruktion z.B. einem Fundament 11, aus Ortbeton ab.The separator housing 1 according to FIG. 1, which is rectangular in cross section and made of cast iron, is pulled up at the top to form a
Aus der Draufsicht nach Fig. 2 ist zu ersehen, daß sich durch die Kreisform des Kragens 2, dessen Durchmesser die Breite des Abscheidegehäuses übertrifft, ein freier Kreissektor ergibt, der das Einschieben eines Koaleszenzeinsatzes 12 in vertikale Führungen 13 ermöglicht.From the top view of FIG. 2 it can be seen that the circular shape of the
