Abstract
Description
Die Erfindung bezieht sich auf Abscheider für Leicht- und/oder Sinkstoffe mit einem Abscheidergehäuse, das eine obere Wartungs- und Kontrollöffnung und einen daran nach oben angeschlossenen Wartungs- und Kontrollschacht aufweist.The invention relates to separators for light and / or sediments with a separator housing which has an upper maintenance and control opening and a maintenance and control shaft connected to it at the top.
Die neue DIN 4034 (IX/90, Teil 1) mit der Bezeichnung "Schächte aus Beton- und Stahlbetonfertigteilen für erdverlegte Abwasserkanäle und -leitungen" schreibt für die Fugen zwischen den Schachtbauteilen eine neue Dichtungsart vor, die die alte Mörtelfuge ersetzen soll.The new DIN 4034 (IX / 90, Part 1) with the designation "Shafts made of prefabricated concrete and reinforced concrete parts for underground sewers and pipes" prescribes a new type of seal for the joints between the shaft components, which is to replace the old mortar joint.
Werkseitig vorgefertigte Schachtbauteile aus Beton und Stahlbeton werden schon seit Jahrzehnten im Kanalbau eingesetzt. Ihre Güteanforderungen an Wasserdichtheit, Korrosionsbeständigkeit und Abriebfestigkeit liegen weit über den in den gültigen Normen geforderten Werten. Durch die neue Muffenverbindung mit einer dauerelastischen Gleitringdichtung nach DIN 4034 neu wird nun auch eine dauerhaft flexible Dichtverbindung geboten, die einen großen Seitenversatz und enorme Schräglagen zuläßt. Diese Dichtungsart setzt sich vom Schachtboden über den Schaftkonus nach oben bis zur Schachtabdeckung fort und bietet somit ein geschlossenes System gegen Eindringen von schädlichen Flüssigkeiten in den Untergrund.Prefabricated manhole components made of concrete and reinforced concrete have been used in sewer construction for decades. Your Quality requirements for watertightness, corrosion resistance and abrasion resistance are far above the values required in the applicable standards. The new sleeve connection with a permanently elastic mechanical seal in accordance with DIN 4034 now also offers a permanently flexible sealing connection that allows a large lateral offset and enormous inclined positions. This type of seal continues from the shaft floor over the shaft cone up to the shaft cover and thus offers a closed system against the penetration of harmful liquids into the ground.
Ein Problem der Abdichtung ist in dieser Norm nicht behandelt. Werksseitig aus Gußeisen, Beton oder Stahlbeton vorgefertigte, unterirdisch einzubauende Abscheider erhalten immer einen oder mehrere Wartungsschächte (DE-PS 26 10 773). Um die Durchmesserunterschiede zwischen Abscheider und Wartungsschacht auszugleichen, sind bei Abscheidern mit großer Nennleistung Übergangsplatten auf den anderen Schachtdurchmesser vorgesehen (EP-A-O 046 277). Sowohl in die Fuge unter der Übergangsplatte als auch in die Fuge unter dem untersten Schachtring wird lediglich eine dünne Mörtelschicht eingebracht, die nur das satte Aufsitzen bewirkt.A problem of sealing is not dealt with in this standard. Separators that are prefabricated in the factory from cast iron, concrete or reinforced concrete and must be installed underground always have one or more maintenance shafts (DE-PS 26 10 773). In order to compensate for the difference in diameter between the separator and the maintenance shaft, transition plates to the other shaft diameter are provided for separators with a high nominal capacity (EP-A-O 046 277). Both a thin layer of mortar is placed in the joint under the transition plate and in the joint under the lowest shaft ring, which only results in a snug fit.
Es stellt sich nunmehr die Aufgabe, die Fugen zwischen Schacht und Übergangsplatte und Abscheider dicht auszuführen, damit bei einem eventuellen Aufstau im Abscheider insbesondere die aufgerahmten Leichtflüssigkeiten durch diese Fuge nicht in den Untergrund gelangen können.The task now is to make the joints between the shaft and the transition plate and the separator tight, so that in the event of a build-up in the separator in particular the light liquids that have been creamed up cannot get into the subsoil through this joint.
Insbesondere bei Abscheidern kleiner Nenngröße sind die oberen Wartungsöffnungen darüber hinaus meist so klein bemessen, daß die Schächte, die die gleichen Abmessungen wie die Kontrollöffnung haben nicht begangen und die Abscheider demzufolge nicht fachmännisch gewartet werden können. Die Aufgabe, auch diese Anschlußstellen dauerhaft und wirksam abzudichten und gleichzeitig die Begehbarkeit sicherzustellen, wird gemäß der Erfindung dadurch gelöst, daß die Übergangsplatte von der kleinen lichten Weite der Kontrollöffnung auf den größeren Durchmesser des begehbaren Schachts springend ausgebildet ist und sowohl gegen das Abscheidergehäuse als auch gegen den Schacht durch dauerelastische Dichtungen abgedichtet ist und sich mit äußeren Abschnitten ihrer Unterseite auf außerhalb der Kontrollöffnung liegenden Flächen-Abschnitten des Abscheidergehäuses abstützt. Vorzugsweise bekommen die Dichtungen und die Anschlußstellen die Form nach DIN 4034 neu. Das den Dichtring aufnehmende Spitzende der Muffenverbindung ist dabei vorzugsweise am Abscheider angeformt. Auf diese Weise kann der Dichtring gut sichtbar und gegen Schäden und Verschmutzungen geschützt auf das untere Bauteil aufgebracht werden. Außerdem bleiben Schmutzteile beim Einbau. nicht auf dem Dichtring liegen. Das obere Bauteil wird beim Aufsetzen ohne Seitenversatz einwandfrei geführt. Durch die Abstützung der Übergangsplatte auf äußeren Flächen-Teilen des Abscheidergehäuses werden Vekehrsbelastungen besser in den Untergrund übertragen.The upper ones are particularly useful for separators of small nominal size In addition, maintenance openings are usually dimensioned so small that the shafts, which have the same dimensions as the inspection opening, cannot be walked on and the separators cannot therefore be professionally serviced. The task of sealing these connection points permanently and effectively and at the same time ensuring that they can be walked on is achieved according to the invention in that the transition plate is designed to jump from the small clear width of the inspection opening to the larger diameter of the accessible shaft and both against the separator housing and is sealed against the shaft by permanently elastic seals and is supported with outer sections of its underside on surface sections of the separator housing lying outside the control opening. The seals and the connection points are preferably given a new shape in accordance with DIN 4034. The tip end of the sleeve connection receiving the sealing ring is preferably integrally formed on the separator. In this way, the sealing ring can be applied to the lower component in a clearly visible manner and protected against damage and soiling. In addition, dirt remains during installation. do not lie on the sealing ring. The upper component is guided correctly when it is put on without lateral offset. By supporting the transition plate on outer surface parts of the separator housing, traffic loads are better transmitted into the ground.
Eine andere Möglichkeit, an der Oberseite des Abscheidergehäuses eine Abstützung für die Übergangsplatte auszubilden, besteht nach einem Ausgestaltungsgedanken darin, ein die innere Schalung bildendes Abscheidergehäuse aus Stahl, Guß, Edelstahl oder Kunststoff mit einem Betonmantel zu umgeben, aus dem das Spitzteil der Dichtfuge oben hervorsteht. Auch hier bilden Abschnitte des Betonmantels die Abstützung für die äußeren Abschnitte der Übergangsplatte. Das Innengehäuse enthält an der Außenseite entsprechende Betonanker zur unlösbaren Verbindung mit dem Beton.Another possibility of forming a support for the transition plate on the top of the separator housing is, according to one design idea, to surround a separator housing made of steel, cast iron, stainless steel or plastic, which forms the inner formwork, from which the pointed part of the sealing joint protrudes at the top . Here too, sections of the Concrete jacket the support for the outer sections of the transition plate. The inner casing contains corresponding concrete anchors on the outside for permanent connection to the concrete.
Die runde Übergangsplatte ist vorzugsweise mit einer exzentrisch angeordneten runden Kontrollöffnung versehen. Durch Drehen der Übergangsplatte kann dadurch der Schacht allseits versetzt werden, um ihn einem Bordstein oder einer Pflasterung anzupassen.The round transition plate is preferably provided with an eccentrically arranged round control opening. By turning the transition plate, the shaft can be moved on all sides to adapt it to a curb or paving.

Der aus Gußeisen z.B. im Vollformverfahren hergestellte Abscheider 1 nach Fig. 1 besitzt oben ein die kreisrunde Wartungsöffnung umgebendes Spitzende 2, das von einer horizontalen Auflagefläche 3 umgeben ist. Das Spitzende 2 dient zum Auflegen eines Gleitdichtrings nach DIN 4034 neu. Die Gegenanlage für die Dichtung befindet sich an einer kreisrunden Übergangsplatte 4 mit exzentrischer Öffnung, die am Außenrand wiederum eine Einlegnut 5 für einen Dichtring nach DIN 4034 neu aufweist, so daß dort ein abgedichteter Schacht mit einem Durchmesser von z.B. 1000 mm aufgebaut werden kann. Durch Drehen der Übergangsplatte auf dem Spitzende des Abscheiders kann der Schacht maximal um die doppelte Exzentrizität seitlich versetzt werden.The
Der Abscheider nach Fig. 2 unterscheidet sich von dem nach Fig. 1 dadurch, daß das z.B. aus Gußeisen bestehende Abscheidergehäuse 1' von einem Betonmantel 6 umgeben ist, der ihm eine größere Auflagefläche im Erdreich verschafft.
