Description

Betonrohr mit eingebauter Sohlschale Bei der Herstellung von Betonrohren in Kreis- und Eiprofil war es bisher nicht möglich, der Forderung der Behörden nachzukommen, Säurebeständigkeit und Abriebfestigkeit durch Einbau von Sohischalen, wie dies beim Ortsbetonkanal üblich-ists in einwandfreier Weise zu gewährleisten0 Es wurden schon in fertige Rohre nachträglich Steinzeugsohischalen eingebaute Nun ist es bei zwei Meter langen Rohren schon arbeitstechnisch sehr schwierig, in ein Eiprofil von 50/75 den Einbau vorzunehmen, Die unregelmäßige Oberfläche mit den vielen Fugen stellt einen weiteren Grund dar, warum man von dieser Vergütung wieder Abstand nimmt0 Die vor Jahren propagierte Kunstharzbeschichtung ist nach Ansicht der Behörden auch keine Ideallösung, weil sie meist zu dünn aufgetragen wurde und auf frischem Beton keine Haftfähigkeit besitzt, was zu Blasenbildung führte D#ie Auskleidung mit PVG und ähnlichen Materialìen stößt auf Schwierigkeiten, da die Ausdehnungs- und Schrumpfungskoeffizienten zwischen Beton und Kunststoff zu groß sindo Gemäß der Erfindung wird ein Betonrohr mit eingebauter Sohlschale geschaffen, die gleiche Dehnungen wie der Beton aufweist, Erfindungsgemäß wird dies dadurch erreicht, daß das Betonrohr mit einem mitgefertigten, über die ganze Länge Sugenlosetl Gerinne versehen ist, Ein bevorzugter Verwendungszweck der erfindungsgemäßen Anordnung ist der Schutz von Betonrohrön im Wasserbau von aggressiven Wässern, insbesondere Säuren. Concrete pipe with built-in base shell In the manufacture of concrete pipes In the circle and egg profile it was not possible to comply with the request of the authorities, Acid resistance and abrasion resistance through the incorporation of soya shells, as in the In-situ concrete sewer is customary to guarantee it in an impeccable manner0 It has already been Stoneware shells subsequently built into finished pipes Now there are two Meter-long pipes are very difficult to work with, in an egg profile of 50/75 to carry out the installation, the irregular surface with the many joints represents Another reason why one refrains from this remuneration again0 The According to the authorities, the synthetic resin coating propagated years ago is also not an ideal solution because it was usually applied too thinly and on fresh concrete has no adhesiveness, resulting in blistering. The PVG lining and similar materials encountered difficulties, since the expansion and contraction coefficients between concrete and plastic are too large o According to the invention, a concrete pipe created with a built-in base shell, which has the same expansion as the concrete, According to the invention this is achieved in that the concrete pipe with a co-manufactured, Sugenlosetl channel is provided over the entire length, a preferred use the arrangement according to the invention is the protection of Betonrohrön in hydraulic engineering aggressive waters, especially acids.

In der Zeichnung ist eine beispielsweise Ausführungs form des Erfindungsgegenstandes dargestellt utzw. zeigen Fig. 1 eine Stirnansicht und Fig. 2 einen Längsschnitt durch das Rohr. In the drawing is an example of execution form of the subject matter of the invention shown demonstrate Fig. 1 is an end view and Fig. 2 is a Longitudinal section through the pipe.

Das aus Beton hergestellte Rohr r ist an einem Ende mit einer Erweiterung e versehen, um das nächste Rohr in diese einstecken zu können. \ Ein vorgefertigtes, als Sohlschale dienendes Gerinne g aus abriebfestem und chemikalien-beständigem Material wird fugenlos über die gesamte Rohrlänge in einem Arbeitsgang mit der Betonspeise spannungsfrei verbunden und anschließend mit dem ausgehärteten Beton haftfest vereinigt. The pipe r made of concrete has an extension at one end e provided so that the next pipe can be inserted into it. \ A prefabricated, A channel g made of abrasion-resistant and chemical-resistant material that serves as the base shell Material is made seamlessly over the entire length of the pipe in one operation with the concrete food Tension-free connected and then firmly bonded to the hardened concrete.

hls Material des Gerinnes g wird zur Erzielung der mit dem Beton übereinstimmenden Dehnung modifiziertes Polyesterharz mit Faserstoffen (Glas, Silan Sisal) und Füllstoffen wie zB. Talkum, Quarzmehl oder Quarzsand verwendet. hls material of the channel g is used to achieve the with the concrete Corresponding elongation modified polyester resin with fiber materials (glass, silane Sisal) and fillers such as. Talc, quartz powder or quartz sand are used.
