Description
Die Erfindung betrifft eine Rohrleitung zum Fördern von Baggergut. Das in der Regel aus einer Mischung von Wasser und Sand bestehende Baggergut muß oft mittels einer Druckleitung vom Ausbaggerungsort zu einer weit entfernten Abladestelle gefördert werden. Dies erfordert einen beträchtlichen Aufwand an Förderleistung, der die Fördergeschwindigkeit in engen Grenzen hält. Abgesehen davon bewirkt das dauernde Scheuern des Baggersandes an der Innenwand der Rohrleitung, insbesondere in deren unterer Hälfte, eine starke Abnutzung der Rohrwand, die ein häufiges Erneuern von Rohrstücken bedingt.The invention relates to a pipeline for conveying dredged material. The dredged material, which usually consists of a mixture of water and sand, must often by means of a pressure line from the excavation site to a distant unloading point be promoted. This requires a considerable effort in terms of conveying capacity, which keeps the conveying speed within narrow limits. Apart from that, that does constant chafing of the dredging sand on the inner wall of the pipeline, in particular in the lower half of the pipe wall, heavy wear and tear, which requires frequent renewal conditional of pipe sections.
Erfindungsgemäß wird diesen Mängeln dadurch entgegengewirkt, daß für die Baggergut-Rohrleitung Rohre verwendet werden, die in ihrer gesamten Länge oder nur an besonders gefährdeten Stellen (wie z. B. bei Richtungsänderungen) einen Innenbelag von Email aufweisen. Dieser Belag ist entweder direkt auf der Rohrinnenwand aufgebrannt, was bei geschlossenen Rohren von kreisrundem Querschnitt die Regel sein wird, oder die Rohrwand ist mit auf der Innenseite emaillierten Schleißplatten belegt. Letztere Art wird bei horizontalen Rohrleitungsstrecken und bei Verwendung offener, mulden- oder rinnenartiger Leitungen in Betracht kommen können. Erstaunlicherweise verleiht eine Emaillierung normaler Art der Röhrinnenwand eine Abriebfestgkeit, die auf anderem Wege bisher kaum erreicht werden konnte.According to the invention, these deficiencies are counteracted in that for The dredged material pipeline can be used in its entire length or pipes only use an interior covering in particularly endangered areas (e.g. when changing direction) of email. This coating is either burned directly onto the inner wall of the pipe, what will be the rule for closed pipes with a circular cross-section, or the pipe wall is covered with wear plates enamelled on the inside. Latter Type is used for horizontal pipeline sections and when using open, troughed or channel-like lines can be considered. Amazingly it gives an enamelling of the normal type of the inner tube wall an abrasion resistance, which on other Paths could hardly be reached so far.
Es ist selbstverständlich, daß die Rohrstücke einer erfindungsgemäßen Baggergut-Rohrleitung auch auf ihrer Außenseite mit einem Emailbelag versehen sein können. Das kann gegebenenfalls erwünscht sein, wenn die Rohrleitung auf oder in feuchtem Gelände verlegt ist. .It goes without saying that the pipe sections of an inventive Dredged material pipeline can also be provided with an enamel coating on its outside can. This may be desirable if the pipeline is on or in has been laid in damp terrain. .
In den Fig. I und 2 der Zeichnung sind zwei Ausführungsformen von Rohren für eine erfindungsgemäße Rohrleitung dargestellt. Nach Fig. I hat ein. schmiedeeisernes Leitungsrohr I einen Innenemailbelag 2 und ist an den Enden mit einem aufgeschweißten Befestigungsflansch 3 versehen; Fig. 2 zeigt ein Rohr ähnlich Fig. I, aber mit einem zusätzlichen äußeren Emailbelag 4.In Figs. I and 2 of the drawings are two embodiments of Pipes for a pipeline according to the invention shown. According to Fig. I has a. wrought iron Line pipe I has an inner enamel covering 2 and is welded on at the ends Mounting flange 3 provided; Fig. 2 shows a tube similar to Fig. I, but with one additional outer enamel covering 4.
