Abstract
Description
Die Erfindung betrifft ein neues Verfahren zur Herstellung von Lager- und Behandlungsbecken für Wässer oder Abwässer, die wasser- oder bodengefährdende und ggf. sogar aggressive Medien enthalten.The invention relates to a new method of manufacture storage and treatment tanks for water or waste water, the water or soil endangering and possibly even contain aggressive media.
Derartige Becken erhalten nach dem ausreichenden Abbinden des Zements eine vorzugsweise mehrlagige Innenbeschichtung, die u. a. nach DIN 4281 vorgeschrieben ist. Vor dem Aufbringen der Beschichtung muß die Innenfläche durch Sandstrahlen von lockeren Betonteilen befreit und die Fläche genügend aufgerauht werden. Im wesentlichen wird die an der Oberfläche eingebundene Zementschlempe entfernt, die keine ausreichende Bindung zum Zuschlag hat. Such pools get after the sufficient setting the cement is preferably a multilayer Interior coating that u. a. prescribed according to DIN 4281 is. Before applying the coating, the Inner surface by sandblasting loose concrete parts freed and the surface roughened sufficiently. in the what is essential is the one integrated on the surface Removed cement slurry that does not have sufficient binding has won.
Das Sandstrahlen ist ein aufwendiger Vorgang, bei dem auch noch die Bestimmungen der Arbeitssicherheit beachtet werden müssen. Die Aufgabe, diesen aufwendigen Arbeitsgang durch eine andere Methode zu ersetzen, wird erfindungsgemäß dadurch gelöst, daß vor Aufbringen der Beschichtung und kurz nach Beginn des Aushärtens des Betons die zu beschichtende Fläche mit unter Druck aufgebrachten Wasserstrahlen abgespült und dadurch aufgerauht wird. Man wartet also nicht bis zum vollständigen Aushärten des Betons, um dann die lockere Schlempe mit Sandkörnern abzuschlagen, sondern die Schlempe und lockere Feinstteile werden vor dem Erhärten fortgespült. Das Abspülen kann schon kurz nach dem Ausformen des Beckens in der Fertigungshalle vorgenommen und weitgehend automatisiert werden. Der Wasserverbrauch ist, wenn die Wasserstrahlen richtig dosiert sind, sehr gering. Nach dem Abspülen wird das Becken zum vollständigen Aushärten auf das Freigelände oder in einen Trockenraum verbracht.Sandblasting is a complex process, which also includes the provisions of occupational safety are still observed Need to become. The task of this complex process will be replaced by another method solved according to the invention in that before the application Coating and shortly after the curing of the Concrete the surface to be coated with under pressure applied water jets and rinsed off is roughened. So you don't wait until complete hardening of the concrete, then the loose To knock off stillage with grains of sand, but the Slurry and loose fines are removed before hardening washed away. Rinsing can start shortly after Forming the basin in the production hall and be largely automated. The water consumption is very good, if the water jets are dosed correctly low. After rinsing, the basin becomes complete curing on the outdoor area or in one Drying room spent.
Die Wasserstrahlen werden unter einem in Abflußrichtung angestellten spitzen Winkel aufgebracht, so daß die losgespülte Schlempe schnell abfließen kann. Als vorteilhaft haben sich pulsierende und bezüglich des Durchmessers und der Stärke einstellbare Strahlen erwiesen. Die Düsenreihe erstreckt sich vorzugsweise über die ganze Höhe der Innenfläche. Das Düsenrohr braucht dann nur noch um die Mittelachse des Beckens gedreht zu werden. Es kann aber auch zweckmäßig sein, nur wenige Düsen an einem kurzen Rohr zu verwenden und diese dann schraubenförmig absteigend durch das Becken zu bewegen. Die weiter oben abgespülte Schlempe behindert dann das Abspülen weiter unten nicht mehr.The water jets are under one in the drain direction applied acute angle so that the washed-off stillage can drain off quickly. As pulsating and with respect to the Beams adjustable in diameter and strength proven. The row of nozzles preferably extends over the whole height of the inner surface. The nozzle tube then needs only to be rotated around the central axis of the pelvis. But it can also be useful to only have a few nozzles use a short tube and then this to descend helically through the pelvis. The stillage washed off above then hinders this Do not rinse further down.
Imprägniermittel sind in der Betontechnologie zur Verbesserung der Oberflächeneigenschaften bekannt. Hier werden diese Imprägniermittel zur Verbesserung der Haftung der Beschichtung angewendet. Da die Imprägniermittel die Eigenschaft haben, in den Beton einzudringen und auch dort eine bessere Bindung der Zuschlagstoffe mit dem Zement zu bewirken, wird erfindungsgemäß vorgeschlagen, die Imprägniermittel während der Abbindephase - der sog. Hydratisierung - des Zements aufzubringen. Die Imprägniermittel gelangen dann zusammen mit dem eingesaugten Hydratisierungswasser tief in den Beton. Übliche Imprägniermittel sind deshalb wasserlösliche Epoxidharze.Impregnants are used in concrete technology Improvement in surface properties known. Here these impregnants are used to improve adhesion applied to the coating. Since the impregnating agent Have property to penetrate into the concrete and also there a better binding of the aggregates with the cement effect is proposed according to the invention, the Impregnation agent during the setting phase - the so-called Hydration - to apply the cement. The Impregnating agents then come together with the sucked hydration water deep into the concrete. Common impregnating agents are therefore water-soluble Epoxy resins.
