Schachtbauwerke, insbesondere Pumpenschächte werden typischerweise als Betonbauwerke ausgeführt, wobei ein meist runder Schacht eine oder mehrere Tauchpumpen enthält.Manhole structures, in particular pump shafts, are typically designed as concrete structures, with a mostly round shaft containing one or more submersible pumps.

Die EP 0 611 269 A1 zeigt einen Pumpenschacht, der aus Beton geformt ist. Dieser Pumpenschacht weist abgeschrägte Wände auf, die einen Sumpf bilden in dessen Zentrum eine oder zwei Tauchpumpen zur Entleerung des Pumpenschachtes angeordnet ist.The EP 0 611 269 A1 shows a pump shaft, which is formed of concrete. This pump shaft has beveled walls which form a sump in the center of which one or two submersible pumps for emptying the pump shaft is arranged.

Die DE 297 12 099 U1 zeigt eine Auskleidung für Kanalschächte mit einem Boden- und Seitenwandteil, wobei diese aus mehreren vorgefertigten Segmenten aus glasfaserverstärktem Kunststoff besteht, die zusammengefügt und dicht miteinander verbunden werden.The DE 297 12 099 U1 shows a liner for manholes with a bottom and side wall portion, which consists of several prefabricated segments of fiberglass reinforced plastic, which are joined together and sealed together.

Das Betonbauwerk sowie die maschinentechnischen Ausrüstungen für den Abwassertransport, unterliegen mehr oder weniger dem korrosiven Verschleiß durch die aggressive Atmosphäre innerhalb des Abwassertransportsystems. Deshalb müssen in der Regel auf Grund des korrosiven Verschleißes nach ca. 10 bis 15 Jahren das Betonbauwerk, sowie die darin befindlichen maschinentechnischen Ausrüstungen, erneuert werden. Für die Betonsanierung haben sich unterschiedliche Verfahren am Markt etabliert. Ein sehr verbreitetes Verfahren ist der Einbau von sogenannten Inlinern, also Auskleidungselementen für die Wandbereiche, welche jedoch nur im zylindrischen Teil des Schachtes Anwendung finden. Das speziell ausgeformte Schachtunterteil, in dem sich die Pumpen befinden, benötigt ein dafür konstruiertes und gefertigtes Einbauteil, welches ohne weitere Anpassungen in den in der Regel mit Bermen oder Vouten versehenen Betonunterteil eines Schachtbauwerks eingebaut werden kann.The concrete structure as well as the mechanical equipment for the transport of waste water are more or less subject to corrosive wear due to the aggressive atmosphere within the waste water transport system. Therefore, due to the corrosive wear and tear, after approx. 10 to 15 years the concrete structure as well as the technical equipment in it have to be renewed. For concrete remediation, different processes have become established on the market. A very common method is the installation of so-called inliners, so lining elements for the wall areas, which, however, find only in the cylindrical part of the shaft application. The specially shaped manhole base, in which the pumps are located, requires a built-in and manufactured built-in part, which can be installed without further adjustments in the usually provided with berms or coves concrete base of a shaft structure.

Ein Beispiel für ein solches Schachtunterteil zeigt die EP 0 767 279 B1 . Die Schrift lehrt einen Schachtboden mit einer geneigten Wand oder einer geneigten Auflage an der die Pumpe angebracht ist. So lässt sich ein möglichst kleiner Pumpensumpf ausbilden. Die Befestigung der Pumpen an der geneigten Wand erfordert jedoch eine aufwändige Verstärkung des Schachtbodenbereichs an dieser Stelle.An example of such a manhole base shows the EP 0 767 279 B1 , The document teaches a shaft bottom with a sloping wall or inclined support to which the pump is attached. This makes it possible to form a pump sump that is as small as possible. However, the attachment of the pumps on the inclined wall requires a complex reinforcement of the shaft bottom area at this point.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde einen Bodeneinsatz für Schachtbauwerke zu schaffen, der einfach und kostengünstig herstellbar und montierbar ist.The present invention is based on the object to provide a bottom insert for manhole structures, which is simple and inexpensive to manufacture and assemble.

Zur Lösung dieser Aufgabe ist vorgesehen, den Bodeneinsatz zu schaffen, der aus einer verlorenen, nahezu halbkugelförmigen Schalung mit einem ebenen, runden Bodenteil besteht, wobei in dem Pumpensumpf eine vertikale Befestigungswand ausgeführt ist, wobei das Bodenteil und die vertikale Befestigungswand einen stabilen, ausgesteiften Winkel darstellt, der die Befestigungsvorrichtung ausbildet. Dadurch wird erreicht, dass der Pumpensumpf sehr klein gehalten werden kann, die Anlagerung von Feststoffen stark unterbunden wird und gleichzeitig eine stabile Befestigungsmöglichkeit für die mindestens eine Pumpe bereitgestellt wird. Des Weiteren wird ein Verfahren zur Sanierung eines Schachtbauwerks infolge von Korrosionsbeschädigung vorgeschlagen, bei dem der beschädigte Schacht geleert wird, ein erfindungsgemäßer Bodeneinsatz maßgenau hergestellt wird, der Bodeneinsatz auf dem Schachtboden befestigt wird, der Bereich zwischen Schachtboden und Bodeneinsatz mit aushärtendem Füllmaterial gefüllt wird und nach dem Aushärten die Maschinenteile insbesondere Rohre und Pumpen montiert werdenTo solve this problem is provided to provide the ground insert, which consists of a lost, almost hemispherical formwork with a flat, round bottom part, wherein in the sump a vertical mounting wall is executed, wherein the bottom part and the vertical mounting wall a stable, stiffened angle represents, which forms the fastening device. This ensures that the pump sump can be kept very small, the addition of solids is strongly prevented and at the same time a stable mounting option for the at least one pump is provided. Furthermore, a method for the rehabilitation of a shaft structure as a result of corrosion damage is proposed, in which the damaged shaft is emptied, a floor insert according to the invention is made dimensionally accurate, the bottom insert is mounted on the shaft bottom, the Area between shaft bottom and bottom insert is filled with hardening filling material and after curing, the machine parts are mounted in particular pipes and pumps

In einer Ausführungsform der Erfindung ist der Bodeneinsatz aus glasfaserverstärktem Kunststoff hergestellt ist, insbesondere durch laminieren auf einer Negativform. Die korrosive Atmosphäre im Schacht erfordert ein Material, das den Bedingungen standhalten kann. Es besteht die Möglichkeit alternative Werkstoffe zu verwenden, die ebenfalls leicht formbar und chemisch stabil sind.In one embodiment of the invention, the bottom insert is made of glass fiber reinforced plastic, in particular by laminating on a negative mold.

In einer weiteren Ausgestaltung ist auf einer Grundplatte ein Winkelprofil vorgesehen, insbesondere auf der Außenseite des Bodeneinsatzes. Dieses Winkelprofil stabilisiert den Bodenbereich, wodurch die Befestigung der Maschinenteile im Schacht ermöglicht ist. Zur Befestigung werden Haltemittel durch die Wand geführt und im Winkelprofil verankert. Die Durchgänge werden vollständig durch Dichtmittel abgedichtet. Die Stabilität wird zusätzlich verbessert, indem eine Konsole zur Befestigung von Maschinenteilen auf der Innenseite des Bodeneinsatzes vorgesehen ist, wobei die Konsole mit dem Winkelprofil verbunden ist. Sind an dem Winkelprofil Anschlussbleche vorgesehen, so lassen sich diese mit der Schachtwand verbinden.In a further embodiment, an angle profile is provided on a base plate, in particular on the outside of the bottom insert. This angle profile stabilizes the floor area, which allows the attachment of the machine parts in the shaft. For fixing holding means are guided through the wall and anchored in the angle profile. The passages are completely sealed by sealant. Stability is further improved by providing a console for mounting machine parts on the inside of the bottom insert, the console being connected to the angle section. If connecting plates are provided on the angle profile, they can be connected to the shaft wall.

Die Grundplatte und / oder das Winkelprofil sind bevorzugt aus Grauguss, Stahl oder Edelstahl hergestellt. Je nach Anforderung ist ein Material zu wählen, das den vorliegenden Bedingungen standhält, insbesondere im Bezug auf Korrosion.The base plate and / or the angle profile are preferably made of gray cast iron, steel or stainless steel. Depending on the requirements, a material must be chosen that can withstand the conditions prevailing, in particular with regard to corrosion.

In einer weiteren Ausgestaltung wird der Bodeneinsatz am Schachtboden mittels Befestigungsmitteln gehalten. Durch Schrauben oder Nagelanker mit Dübeln lässt sich ein Verrücken des Bodeneinsatzes im Schacht verhindern, insbesondere in der Bauphase, in der ein Schacht saniert wird.In a further embodiment, the bottom insert is held at the bottom of the shaft by means of fastening means. By screwing or nail anchors with dowels can be a dislocation of the bottom insert in the shaft prevent, especially in the construction phase in which a shaft is rehabilitated.

In einer weiteren Ausgestaltung weist der Bodeneinsatz mindestens eine verschließbare Öffnung auf. Diese dient beim Einführen des Bodeneinsatzes in den Schacht dazu die Luft unter dem Bodeneinsatz entweichen zu lassen.In a further embodiment, the bottom insert has at least one closable opening. This serves to allow the air to escape under the ground when inserting the bottom insert into the shaft.

Des weiteren betrifft die Erfindung ein Verfahren zur Sanierung eines Schachtbauwerks infolge von Korrosionsbeschädigung, wobei der beschädigte Schacht geleert wird, ein oben beschriebener Bodeneinsatz maßgenau hergestellt wird, der Bodeneinsatz auf dem Schachtboden befestigt wird, der Bereich zwischen Schachtboden und Bodeneinsatz mit aushärtendem Füllmaterial gefüllt wird und nach dem Aushärten die Maschinenteile insbesondere Rohre und Pumpen montiert werden. Auf diese weise lassen sich Schachtbauwerke sanieren. Selbstverständlich lassen sich auch neue Schachtbauwerke mit einem erfindungsgemäßen Bodeneinsatz ausstatten.Furthermore, the invention relates to a method for rehabilitation of a shaft structure due to corrosion damage, the damaged shaft is emptied, a soil insert described above is made dimensionally accurate, the bottom insert is fixed to the shaft bottom, the area between the shaft bottom and bottom insert is filled with hardening filler and After curing, the machine parts are mounted in particular pipes and pumps. In this way, manhole structures can be rehabilitated. Of course, new shaft structures can be equipped with a ground insert according to the invention.

In manchen Fällen ist es nötig, den gesamten Schacht zu sanieren, also auch die Schachtwand. Hierfür wird der gesamte Schacht mit einer neuen Innenwand versehen, wobei eine Verbindung zwischen der neuen Innenwand und dem Bodeneinsatz hergestellt wird. Die Verbindung kann bei einem Bodenteil aus glasfaserverstärktem Kunststoff als Anschlussteil in das Bodenteil einlaminiert sein. So kann beispielsweise ein Anschlussteil aus Polypropylen oder Polyäthylen einlaminiert sein, das mit einer Innenwand, die ebenfalls aus Polypropylen oder Polyäthylen hergestellt ist, verschweißt wird. Es ist auch möglich, das zylindrische Anschlussteil aus GFK herzustellen, wobei dieses dann direkt am Bodeneinsatz anlaminiert ist und daher kein Anschlussteil erforderlich ist.In some cases, it is necessary to rehabilitate the entire shaft, including the shaft wall. For this purpose, the entire shaft is provided with a new inner wall, wherein a connection between the new inner wall and the bottom insert is made. The compound can be laminated at a bottom part of glass fiber reinforced plastic as a connection part in the bottom part. Thus, for example, a connection part made of polypropylene or polyethylene laminated with an inner wall, which is also made of polypropylene or polyethylene, is welded. It is also possible to produce the cylindrical connection part of fiberglass, which is then laminated directly to the bottom insert and therefore no connection part is required.
