Material und Vorrichtung zum Verfüllen von Tanks
10Material and equipment for filling tanks
10
Stillgelegte, unterirdische Tanks werden häufig in der Erde belassen, da das Ausgraben und Entfernen sehr aufwendig und 'teuer ist. Da stillgelegte Tanks, beispielsweise durch Korrosion ihre Standfestigkeit verlieren und einstürzen können, müssen sie mit einem tragfähigen Material verfüllt werden. Es ist bekannt, als Material zum Verfüllen von stillgelegten, unterirdischen Tanks Sand zu verwenden. Das gleichmäßige Verfüllen eines Tankhohlraums mit Sand erfordert noch in erheblichem Umfang Einsatz von Handarbeit und ist daher zeitaufwendig.Disused underground tanks are often left in the ground because digging them out and removing them is very time-consuming and expensive. Since disused tanks can lose their stability and collapse, for example due to corrosion, they must be filled with a load-bearing material. Sand is a known material for filling disused underground tanks. Filling a tank cavity evenly with sand still requires a considerable amount of manual labor and is therefore time-consuming.
Der Erfindung liegt die Aufgabe zugrunde, ein tragfähiges Material bereit zu stellen, das ein besonders wirtschaftliches und rasches Verfüllen stillgelegter, unterirdischer Tanks ermöglicht.The invention is based on the object of providing a load-bearing material that enables particularly economical and rapid filling of disused underground tanks.
Die Aufgabe wird erfindungsgemäß durch ein Granulat und/oder eine Staubfraktion aus Porenbeton gelöst, wobei der Porenbeton durch Mischen von feinstgemahlenem Quarzsand, Kalk, Zement, Naturgips und Aluminiumpulver, Anteigen dieser Mischung mit Wasser, Formen und anschließender Dampfhärtung hergestellt ist und wobei Quarzsand, Kalk und Wasser jeweils in einer Menge von über 10%, Zement und Naturgips in einer Menge von 1-10%, sowie Aluminiumpulver in einer Menge von unter 1% eingesetzt werden. Das MaterialThe object is achieved according to the invention by a granulate and/or a dust fraction of aerated concrete, whereby the aerated concrete is produced by mixing finely ground quartz sand, lime, cement, natural gypsum and aluminum powder, making this mixture into a paste with water, molding and then steam hardening, and whereby quartz sand, lime and water are each used in an amount of over 10%, cement and natural gypsum in an amount of 1-10%, and aluminum powder in an amount of less than 1%. The material
- 2 - " " W04G001- 2 - " " W04G001
hat vorzugsweise ein spezifisches Gewicht von 350-800g/dm3. Eine vorteilhafte Korngröße des Granulats liegt in einem Bereich von 2-20 nun. Ohne Nachteil kann dem Granulat auch einen Anteil der Staubfraktion aus Porenbeton zugemischt sein.preferably has a specific weight of 350-800g/dm 3 . An advantageous grain size of the granulate is in a range of 2-20 mm. A proportion of the dust fraction from aerated concrete can also be mixed into the granulate without any disadvantage.
Das erfindungsgemäße Material ist vergleichsweise leicht, trocken und porös. Es läßt sich mit geringem Aufwand transportieren und kann mit Hilfe einer Druckluftfördereinrichtung, beispielsweise von einem Silofahrzeug aus, unmittelbar in den zu verfüllenden Tankraum eingebracht werden. Hierbei hat sich gezeigt, daß das Granulat bei der Blasförderung gut verteilt werden kann und eine überraschend hohe Lagerdichte und Tragfähigkeit erreicht, so daß eine anschließende Nachverdichtung entbehrlich ist. Trotz der erreichten Lagerstabilität kann das erfindungsgemäße Material auch nach Jahren wieder aus dem Tank entfernt werden, wenn dieser beispielsweise ausgegraben und entsorgt werden soll. Ein weiterer Vorteil des erfindungsgemäßen Materials ist darin zu sehen, daß es aufgrund seiner Porosität in der Lage ist, Restfeuchtigkeit aus dem Tankreinigungsprozeß aufzusaugen und zu binden. Vorteilhaft ist weiterhin, daß das Granulat aus einem Porenbetonmaterial hergestellt sein kann, das bei der Herstellung von Porenbetonblöcken oder Porenbetonplatten abfällt. Das Material ist daher einfach und kostengünstig zu gewinnen.The material according to the invention is comparatively light, dry and porous. It can be transported with little effort and can be introduced directly into the tank space to be filled with the aid of a compressed air conveyor, for example from a silo vehicle. It has been shown that the granulate can be distributed well during the blowing process and achieves a surprisingly high storage density and load-bearing capacity, so that subsequent recompaction is unnecessary. Despite the storage stability achieved, the material according to the invention can be removed from the tank even after years, for example if it is to be dug up and disposed of. A further advantage of the material according to the invention is that, due to its porosity, it is able to absorb and bind residual moisture from the tank cleaning process. Another advantage is that the granulate can be made from an aerated concrete material that is left over during the production of aerated concrete blocks or aerated concrete slabs. The material is therefore easy and inexpensive to obtain.
Mit der Erfindung wird weiterhin eine Vorrichtung geschaffen, mit der das Verfüllen von stillgelegten, unterirdisehen Tanks mit einem Granulat oder einer Staubfraktion aus Porenbeton besonders einfach und wirtschaftlich durchführbar ist. Die Vorrichtung weist ein nach Abnahme des Tankdeckels in die Tanköffnung einsetzbares, abgewinkeltes Blasrohr auf, das von einer an dem Deckelflansch des Tanks befestigbaren Halterung getragen wird und an den Förderschlauch einer Druckluftfördereinrichtung anschließbar ist.The invention further provides a device with which the filling of disused, underground tanks with a granulate or a dust fraction made of aerated concrete can be carried out particularly easily and economically. The device has an angled blowpipe that can be inserted into the tank opening after the tank lid has been removed, which is carried by a bracket that can be attached to the lid flange of the tank and can be connected to the conveyor hose of a compressed air conveyor device.
- 3 - W04G001- 3 - W04G001
Die Vorrichtung umfaßt weiterhin einen den Tankschacht verschließenden Deckel, der eine mit einem Filter verschlossene Luftaustrittsöffnung hat. Der lose auf den Schacht auflegbare Deckel wird erfindungsgemäß an seinen Rändern mittels Sandsäcken beschwert. Zur Abdichtung des Deckels gegenüber dem Tankschacht können zwischen dem Deckel und dem Tankschacht Streifen aus Glas- oder Steinwolle angeordnet sein.The device also includes a lid that closes the tank shaft and has an air outlet opening that is closed with a filter. According to the invention, the lid, which can be placed loosely on the shaft, is weighted down at its edges using sandbags. To seal the lid from the tank shaft, strips of glass or rock wool can be arranged between the lid and the tank shaft.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below using an embodiment shown in the drawing.
Die Zeichnung zeigt einen Querschnitt durch einen unterirdischen Tank 1 mit einer in einem Schacht 2 liegenden Tanköffnung 3, die einen Flansch 4 zur Befestigung eines bereits abgenommenen Deckels aufweist. Zum Verfüllen des Tanks 1 mit Porenbetongranulat ist ein rechtwinklig abgebogenes Blasrohr 5 mit Hilfe einer Halterung 6 an dem Flansch 4 festgeschraubt. Innerhalb des Tanks 1 ist das Blasrohr 5 mit einem geraden Verlängerungsstück 7 verlängert. An das obere, in dem Schacht 2 befindliche Ende des Blasrohrs 5 ist ein Förderschlauch 8 angeschlossen, der zu einem nicht dargestellten Silofahrzeug mit einer Druckluftfördereinrichtung führt. Der Schacht 2 ist mit einem Deckel 9 verschlossen, der allseits auf dem Rand des Schachts 2 aufliegt. Zwischen dem Deckel 9 und dem Schacht 2 sind zur Abdichtung Streifen 10 aus Glaswolle angeordnet. Der Rand des Deckels 9 ist ringsum mit Sandsäcken 11 beschwert, damit der auf dem Deckel 9 lastende Druck während der Blasförderung den Deckel 9 nicht anheben kann. Der Deckel 9 weist eine Luftaustrittsöffnung 12 auf, die auf der Deckeloberseite mit einem luftdurchlässigen Filtersack 13 verschlossen ist. Bei Bedarf können auch mehrere Luftaustrittsöffnung 12 mit einem Filtersack 13 vorgesehen sein.The drawing shows a cross section through an underground tank 1 with a tank opening 3 in a shaft 2, which has a flange 4 for fastening a cover that has already been removed. To fill the tank 1 with aerated concrete granulate, a blowpipe 5 bent at a right angle is screwed to the flange 4 using a bracket 6. Inside the tank 1, the blowpipe 5 is extended with a straight extension piece 7. A conveyor hose 8 is connected to the upper end of the blowpipe 5 in the shaft 2, which leads to a silo vehicle (not shown) with a compressed air conveyor device. The shaft 2 is closed with a cover 9, which rests on the edge of the shaft 2 on all sides. Strips 10 made of glass wool are arranged between the cover 9 and the shaft 2 for sealing. The edge of the lid 9 is weighted down all around with sandbags 11 so that the pressure on the lid 9 during blowing cannot lift the lid 9. The lid 9 has an air outlet opening 12 which is closed on the top of the lid with an air-permeable filter bag 13. If required, several air outlet openings 12 with a filter bag 13 can also be provided.

Bei dem dargestellten Beispiel ist der von der Tanköffnung 3 entferntere, hintere Abschnitt des Tanks 1 unter Verwendung des Verlängerungsstücks 7 bereits mit Porenbetongranulat 14 verfüllt worden. Zum Verfüllen des vorderen Abschnitts des Tanks 1 wird das Verlängerungsstücks 7 abgenommen und der Tank 1 bis zur Tanköffnung verfüllt, wobei das Blasrohr 5 bei Bedarf in seiner Halterung 6 auch gedreht werden kann.In the example shown, the rear section of the tank 1, further away from the tank opening 3, has already been filled with aerated concrete granulate 14 using the extension piece 7. To fill the front section of the tank 1, the extension piece 7 is removed and the tank 1 is filled up to the tank opening, whereby the blowpipe 5 can also be rotated in its holder 6 if necessary.
