Description
Die Erfindung betrifft einen Rohrabschnitt aus bewehrtem
Stahlbeton nach dem Oberbegriff des Anspruchs 1. Ein derartiges
Gerät ist bereits aus der AT-A-382 224 bekannt.The invention relates to a pipe section made of reinforced
Reinforced concrete according to the preamble of
Derartige Rohrabschnitte werden mittels Druckpressen in das Erdreich vorgeschoben, wobei nach Einschieben eines ersten Rohrabschnittes die Pressen zurückgefahren, ein zweiter Rohrabschnitt im Pressenschacht an den ersten Rohrabschnitt angesetzt und dann mittels der Presse nachgeschoben wird.Such pipe sections are by means of pressure presses in the Soil advanced, after inserting a first Pipe section the presses retracted, a second Pipe section in the press shaft to the first pipe section is set up and then pushed by means of the press.
Zum flüssigkeitsdichten Aneinanderfügen der aufeinanderfolgenden Rohrabschnitte ist bekannt, an dem - bezogen auf die Vorschubrichtung - hinteren Ende eines Rohrabschnittes eine Stahlmanschette anzuordnen, die das axiale Ende des Rohrabschnittes übergreift. Die Stahlmanschette ist im Außendurchmesser geringfügig kleiner als der Außendurchmesser des Rohrabschnittes ausgeführt und wird in dem übergreifenden Bereich mittels Ankern in der Rohrwandung festgelegt. Über den Umfang verteilt, sind - bevorzugt mit äquidistanten Abständen zueinander - mehrere radial einragende Anker vorgesehen.For liquid-tight joining of the successive Pipe sections is known on the - based on the Feed direction - rear end of a pipe section a To arrange steel sleeve, which is the axial end of the pipe section spreads. The steel sleeve is in the outer diameter slightly smaller than the outside diameter of the Pipe section executed and is in the overarching Area defined by anchoring in the pipe wall. over the circumference is distributed - preferably with equidistant Distances to each other - several radially protruding anchors intended.
Ein anzusetzender Rohrabschnitt greift mit seinem im Durchmesser verringerten Anschlußende in die Stahlmanschette ein, wobei in einer Umfangsnut oder auf einem Stufenfalz des Anschlußendes ein elastischer Dichtring, ein Fugenband oder dgl. angeordnet ist, um einen flüssigkeitsdichten Anschluß zu gewährleisten.A pipe section to be attached engages with its diameter reduced connection end into the steel sleeve, being in a circumferential groove or on a step fold of the An elastic sealing ring, a joint tape or The like. is arranged to a liquid-tight connection to ensure.
Diese Rohrverbindung weist im allgemeinen eine ausreichende Dichtigkeit bis zu Drücken von 0,5 bar auf. Bei höheren Drücken treten zwischen dem Rohrabschnitt und der an ihm verankerten Stahlmanschette Undichtigkeiten auf. Daher wird zwischen der Stahlmanschette und dem mit ihr verankerten Rohr eine elastische Dichtung angeordnet oder an der Stoßfuge aufeinanderfolgender Rohrabschnitte ein Fugenband vorgesehen. Dennoch mußte festgestellt werden, daß bei höheren Drücken Undichtigkeiten nicht mit Sicherheit ausgeschlossen werden konnten. Bei im Vorpreßverfahren hergestellten, druckführenden Leitungen ist daher oft ein zulässiger Maximaldruck von 1,5 bar angegeben. Wird eine Leitung im Vorpreßverfahren in Natur- oder Wasserschutzgebieten unter Gewässern oder sonstigen erhöhten Anforderungen verlegt, müssen höhere Druckdichtigkeiten gewährleistet sein; das gleiche gilt für im Vortriebverfahren herzustellende Druckleitungen.This pipe connection generally has a sufficient Tightness up to pressures of 0.5 bar. At higher Pressures occur between the pipe section and that on it anchored steel sleeve leaks. Therefore between the steel cuff and the one anchored to it An elastic seal is arranged or attached to the pipe Butt joint of successive pipe sections a joint tape intended. Nevertheless, it had to be found that at higher pressures leaks are not certain could be excluded. In the pre-pressing process manufactured, pressurized lines is therefore often a permissible maximum pressure of 1.5 bar specified. Will one Prepress process management in nature or water protection areas under water or other increased requirements installed, higher pressure tightness must be guaranteed be; the same applies to tunneling pressure lines to be manufactured.
