Description
Abdeckung für Räumerlaufflächen an Klärbecken. * Die Erfindung bezieht sich auf Räumerlaufflächen an Klärbecken in 5 mm Edelstahl. Cover for scraper running surfaces on clarification tanks. * The invention relates to scraper running surfaces on clarification tanks made of 5 mm stainless steel.
Auf vielen Kläranlagen bestehen die Kärbecken aus bewehrtem Ortbeton, auf deren Außenwänden die Fahrwerke der Schlammräumer laufen, sie werden mit Drehstrommotoren angetrieben. j; Durch das Befahren der Lauf flächen, und Witterungseinflüsse,In many sewage treatment plants, the sludge tanks are made of reinforced in-situ concrete, on whose outer walls the sludge scrapers’ undercarriages run; they are driven by three-phase motors. j; Driving on the running surfaces and weather influences,

spachtelungen haben oft zu keinem Erfolg geführt,da sich der Beton von ihnen löste.Fillings often did not lead to success because the concrete came away from them.
Mit verschiedenen Abdeckungen aus Stahlblechelemente wurden von mir Versuche durchgeführt,wobei sich eine Abdeckung aus 5 mm Edelstahl Ü-Profil bewährt hat,was ein zweijähriger störungsfreier Betrieb bewies.I carried out tests with various covers made of sheet steel elements, whereby a cover made of 5 mm stainless steel U-profile proved to be effective, as demonstrated by two years of trouble-free operation.
Der Erfindung liegt die Aufgabe zugrunde,die Betonlaufflächen an Klärbecken,die der Witterung und Umweldbelastungen ausgesetzt sind zu schützen und damit einen störungsfreien Räurcsrbetrieb zu gewährleiste· The invention is based on the task of protecting the concrete running surfaces on sewage treatment tanks that are exposed to weather and environmental stress and thus ensuring trouble-free sewage treatment operations.
