Description

Hochdruckrohr aus Eisenbeton mit Innenverschalung. Rohre aus Eisenbeton sind als Wasserleitungsrohre nur für Drücke unterhalb 3 Atmosphären verwendbar. Um solche Rohre für höheren Druck geeignet zu machen, hat man es bisher für unumgänglich notwendig erachtet, die Gesamtfestigkeit durch eine Innenverkleidung aus Eisenblech zu erhöhen. Hierdurch werden aber die Herstellungskosten derart erhöht, daß der Preisunterschied gegenüber Gußeisenrohren verschwindet; aus diesem Grunde haben mit einer Blechverkleidung versehene Eisenbetonrohre keine praktische Verwendung gefunden.High-pressure pipe made of reinforced concrete with internal cladding. Reinforced concrete pipes can only be used as water pipes for pressures below 3 atmospheres. In order to make such pipes suitable for higher pressures, it was previously unavoidable considered necessary, the overall strength by an inner lining made of iron sheet to increase. However, this increases the manufacturing costs so that the Price difference compared to cast iron pipes disappears; for this reason have Reinforced concrete pipes provided with sheet metal cladding have no practical use found.

Vorliegende Erfindung stellt sich die Aufgabe, die Verwendung einer Blechverkleidung für Hochdruckrohre aus Eisenbeton überflüssig zu machen. Sie fußt auf der Erkenntnis, daß es ohne weiteres möglich ist, einer erhöhten Beanspruchung durch entsprechende Verstärkung der Eisenarmierung allein Rechnung zu tragen und daß solche Rohre dem Druck Widerstand bieten müßten, sofern das Eindringen des unter Druck stehenden Wassers in die feinen Haarrisse des Betons, das die Brüche im Beton veranlaßt, verhindert wird. Es handelt sich finit anderen Worten nur darum, die Rohrinnenwand gegen das Wasser abzudichten. Diese Wirkung kann aber mit einer Holzverkleidung viel zuverlässiger erreicht werden als mit einer Eisenverkleidung, weil Holz durch Wasser zum Quellen gebracht und die Dichtung daher unter dem Wasserdruck verbessert wird. Während die Bleche bei Herstellung der bekannten Verkleidung durch entsprechende Hilfsmittel gegeneinander abgedichtet werden müssen, kann das Zusam= menfügen der Holzschalung ohne besondere Sorgfalt geschehen; vorhandene Fugen werden durch das Quellen des Holzes zuverlässiger abgedichtet, als dies durch Anwen= dung eines Dichtungsmittels möglich wäre.The present invention has the object of using a To make sheet metal cladding for high-pressure pipes made of reinforced concrete superfluous. She is based based on the knowledge that it is easily possible, an increased stress to take into account solely by reinforcing the iron reinforcement and that such pipes would have to offer resistance to the pressure, provided that the penetration of the under Pressure of standing water into the fine hairline cracks of the concrete, which causes the breaks in the concrete caused, prevented. In other words, it is only about the To seal the inner wall of the pipe against the water. However, this effect can be achieved with wood paneling can be achieved much more reliably than with iron cladding because wood is through Brought water to swell and the seal therefore improves under the water pressure will. While the sheets in the production of the known cladding by appropriate Aids must be sealed against each other, the joining of the Wooden formwork done without special care; existing joints are replaced by the Swelling of the wood is more reliably sealed than by using a sealant it is possible.

Die Herstellung der Hochdruckrohre kann in der Weise erfolgen, daß die Schalung als Außenverkleidung auf den für den Rohrguß erforderlichen verschiebbaren Kern gebracht wird, oder es wird ein die Verschalung bildendes Holzrohr unmittelbar als Kernmodell verwendet. In beiden Fällen bietet die Holzverschalung eine Stützung für das gegossene Eisenbetonrohr während des Erhärtens, so daß die Vorschiebung des Kernes noch vor beendeter Abbindung des Zementes erfolgen kann. Auf diese Weise ist auch die Möglichkeit geboten, langsam abbindende Zementsorten wie gewöhnlichen Portlandzement zu verwenden, während die Herstellung von Eisenbetonrohren mit der bekannten Blechverkleidung, clie erst nach Fertigstellung des Eisenbetonrohres eingesetzt wird, ebenso wie die Herstellung unverschalter'. Eisenbetonrohre rasch abbindende besondere Zemente erforderlich macht.The high pressure pipes can be manufactured in such a way that the formwork as external cladding on the slidable required for the pipe casting Core is brought, or there is a wooden pipe forming the cladding directly used as the core model. In both cases, the wooden cladding provides support for the cast reinforced concrete pipe during hardening, so that the advancement the core can take place before the cement has set. In this way there is also the option of slow-setting types of cement such as ordinary To use portland cement while making reinforced concrete pipes with the known sheet metal cladding, which is only used after the reinforced concrete pipe has been completed will, as well as the manufacture of uninterrupted '. Reinforced concrete pipes requires special cements that set quickly.

Die Verschalungsrohre werden vorteilhaft aus Brettern zusammengefügt, die durch stumpfen Stoß, durch Falz oder mittels Feder und Nut verbunden sind. In gleicher Weise kann auch die Verbindung der Bretter in der Längsrichtung erfolgen. Dabei ist es zweckmäßig, nebeneinanderiiegende Bretter in der Längsrichtung gegeneinander zu versetzen, um Undichtheiten an der Stoßstelle der einzelnen Schüsse des Verschalungsrohres zu vermeiden.The casing tubes are advantageously put together from boards, which are connected by a butt joint, by a fold or by means of a tongue and groove. In the boards can be connected in the same way in the longitudinal direction. It is useful to place boards lying next to one another in the longitudinal direction against one another to move to leakage at the joint of the individual sections of the casing pipe to avoid.
