Description

Die Erfindung betrifft einen Rohrabschnitt aus bewehrtem Stahlbeton nach dem Oberbegriff des Anspruchs 1.The invention relates to a pipe section made of reinforced steel concrete according to the preamble of claim 1.

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 pushed into the ground by means of pressure presses, the presses being retracted after insertion of a first pipe section, a second pipe section being placed in the press shaft on the first pipe section and then being pushed in 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 the liquid-tight joining of the successive pipe sections, it is known to arrange a steel sleeve on the rear end of a pipe section, based on the feed direction, which overlaps the axial end of the pipe section. The outer diameter of the steel sleeve is slightly smaller than the outer diameter of the pipe section and is fixed in the overlapping area by means of anchors in the pipe wall. Distributed over the circumference, a plurality of radially projecting anchors are provided, preferably with equidistant distances from one another.

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 reduced diameter end in the steel sleeve, wherein an elastic sealing ring, a joint tape or the like is arranged in a circumferential groove or on a step fold of the connection end in order to ensure a liquid-tight connection.

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 sufficient tightness up to pressures of 0.5 bar. At higher pressures, leaks occur between the pipe section and the steel sleeve anchored to it. An elastic seal is therefore arranged between the steel sleeve and the pipe anchored to it, or a joint tape is provided on the butt joint of successive pipe sections. Nevertheless, it had to be determined that leaks at higher pressures could not be ruled out with certainty. A permissible maximum pressure of 1.5 bar is therefore often given for pressurized lines manufactured using the pre-compression process. If a line is laid in the pre-compression process in nature or water protection areas under water or other increased requirements, higher pressure tightness must be guaranteed; the same applies to pressure lines to be manufactured using the jacking method.

Der Erfindung liegt die Aufgabe zugrunde, Vorpreßrohrabschnitte der gattungsgemäßen Art derart weiterzubilden, daß ein hochdruckfester Anschluß der Stahlmanschette an der Rohrwandung gewährleistet ist.The invention has for its object to develop prepress tube sections of the generic type such that a high pressure resistant connection of the steel sleeve to the tube wall is guaranteed.

Die Aufgabe wird erfindungsgemäß nach den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The object is achieved according to the characterizing features of claim 1.

Die im Bereich des dem Rohrabschnitt zugewandten Endes der Manschette radial innen angeordnete, umlaufende Profil stellt eine hochwirksame Umläufigkeitsdichtung nach dem Prinzip einer Labyrinthdichtung dar, wobei zugleich eine mechanisch innige Verbindung mit der Rohrwandung erzielt ist. Dieser Verbund aus Rohrabschnitt und Stahlmanschette kann eine Wasserdruckfestigkeit von 5 bar und mehr aufweisen.The circumferential profile arranged radially on the inside in the region of the end of the sleeve facing the pipe section represents a highly effective circumferential seal based on the principle of a labyrinth seal, whereby at the same time a mechanically intimate connection with the pipe wall is achieved. This combination of pipe section and steel sleeve can have a water pressure resistance of 5 bar and more.

Die Anordnung des umlaufenden Profils, welches bevorzugt aus Stahl besteht und an der Innenwand der Stahlmanschette angeschweißt ist, ermöglicht hochdruckfeste Verbindungen, die auch Drücken, insbesondere Wechseldruckbelastungen von bis zu 5 bar und mehr standhalten. Bevorzugt endet das innere Profil axial an der durch die Stirnseite des inneren Endes der Manschette bestimmten Ebene, wodurch gewährleistet ist, daß die vorgefertigten Manschetten leicht handhabbar sind, da keine über die axiale Stirnseite des Manschettenmantels vorstehenden Teile auftreten.The arrangement of the circumferential profile, which is preferably made of steel and is welded to the inner wall of the steel sleeve, enables high-pressure-resistant connections which can also withstand pressures, in particular alternating pressure loads of up to 5 bar and more. The inner profile preferably ends axially at the plane determined by the end face of the inner end of the sleeve, which ensures that the prefabricated sleeves are easy to handle, since no parts projecting beyond the axial end face of the sleeve sleeve occur.

Wie Fig. 1 zeigt, wird ein erster Rohrabschnitt 1 durch Ansetzen eines zweiten Rohrabschnittes 2 verlängert und durch Aufbringen einer axialen Kraft in Vorschubrichtung 3 vorgepreßt. Jeder Rohrabschnitt 1, 2 besteht aus bewehrtem Stahlbeton, wobei die Enden 1a, 1b, bzw. 2a, 2b der Rohrabschnitte als Anschlußenden ausgebildet sind. Die - bezogen auf die Vorschubrichtung 3 - hinteren Anschlußenden 1b, 2b weisen eine in der Rohrwandung 4 verankerte Stahlmanschette 5 auf, die das Anschlußende 2a eines anzusetzenden Rohrabschnittes 2 übergreift.As shown in FIG. 1, a first pipe section 1 is extended by attaching a second pipe section 2 and pressed in the feed direction 3 by applying an axial force. Each pipe section 1, 2 consists of reinforced reinforced concrete, the ends 1a, 1b and 2a, 2b of the pipe sections being designed as connecting ends. The - in relation to the feed direction 3 - rear connection ends 1b, 2b have a steel sleeve 5 anchored in the pipe wall 4, which overlaps the connection end 2a of a pipe section 2 to be attached.

Wie Fig. 2 zeigt, ist die Stahlmanschette 5 in ihrem Außendurchmesser d geringfügig kleiner ausgeführt als der Außendurchmesser D des Rohrabschnittes 1 bzw. 2. Die Stahlmanschette 5 liegt somit innerhalb der durch die Rohraußenfläche bestimmten Hüllkurve.As shown in FIG. 2, the outer diameter d of the steel sleeve 5 is slightly smaller than the outer diameter D of the pipe section 1 or 2. The steel sleeve 5 is thus within the envelope curve determined by the outer pipe surface.

Die Stahlmanschette 5 übergreift den mit verringertem Durchmesser ausgeführten Endabschnitt 4a des Rohres 1, wobei die Manschette 5 über etwa 40 bis 50% ihrer Länge den Rohrabschnitt 1 übergreift. Im übergreifenden Bereich ist die Stahlmanschette 5 mittels Ankern 6, insbesondere Kopfankern in der Rohrwandung 4 festgelegt. Wie die Fig. 3 und 4 zeigen, sind über den Umfang der Stahlmanschette 5 eine Vielzahl von Ankern 6 vorgesehen, die bevorzugt äquidistante Abstände voneinander aufweisen. Aus Fig. 2 ist ersichtlich, daß die Anker 6 einen ersten etwa radial einragenden Abschnitt 6a aufweisen, an den ein radial nach innen und axial zum inneren Ende 5a der Manschette 5 ragender Abschnitt 6b anschließt, dessen freies Ende einen Verankerungskopf 6c aufweist. Die Abschnitte sind aus Rundmaterial vorgesehen. Es kann zweckmäßig sein, die Anker 6 unter Neigung anzuordnen oder Flachstahlbetonanker zu verwenden.The steel sleeve 5 overlaps the end section 4a of the pipe 1 with a reduced diameter, the sleeve 5 overlapping the pipe section 1 over approximately 40 to 50% of its length. In the overlapping area, the steel sleeve 5 is fixed in the tube wall 4 by means of anchors 6, in particular head anchors. 3 and 4 show, a plurality of anchors 6 are provided over the circumference of the steel sleeve 5, which preferably have equidistant distances from one another. From Fig. 2 it can be seen that the armatures 6 have a first approximately radially projecting section 6a, to which a section 6b projecting radially inward and axially to the inner end 5a of the sleeve 5 connects, the free end of which has an anchoring head 6c. The sections are made of round material. It may be appropriate to arrange the anchors 6 at an incline or to use flat steel concrete anchors.

Der im Durchmesser verringerte Anschlußabschnitt 2a des anzusetzenden Rohrabschnittes 2 liegt mit radialem Spiel innerhalb der Manschette 5, wobei zur Abdichtung des Anschlußendes 2a innerhalb der Manschette 5 eine Dichtung 7 angeordnet ist. Die Dichtung 7 liegt in einer äußeren Umfangsnut 7a (Fig. 2) des Anschlußendes 2a und kann auch durch ein elastisches Fugenband oder dgl. gebildet sein. Anstelle einer Umfangsnut 7a ist auch ein Stufenfalz zweckmäßig, wie in Fig. 1 angedeutet.The reduced diameter connecting section 2a of the pipe section 2 to be attached lies with radial play within the sleeve 5, a seal 7 being arranged inside the sleeve 5 to seal the connecting end 2a. The seal 7 lies in an outer circumferential groove 7a (FIG. 2) of the connection end 2a and can also be formed by an elastic joint tape or the like. Instead of a circumferential groove 7a, a step fold is also expedient, as indicated in FIG. 1.

Zur Erzielung eines hochdruckfesten Anschlusses der Manschette 5 an dem ihm tragenden Rohr 1 ist die Manschette 5 im Bereich ihres dem Rohrabschnitt 1 zugewandten inneren Endes 5a mit einem radial inneren, umlaufenden Profil 10 versehen, welches aus Stahl besteht und auf der Innenseite der Manschette 5 angeschweißt ist. Die Schweißverbindung 11 ist bevorzugt flüssigkeitsdicht ausgeführt. Das umlaufende Profil 10 ist im Stahlbeton der Rohrwand 4 eingegossen, wodurch eine Art Labyrinthdichtung gebildet ist, welche eine dichte wasserdruckfeste Verbindung der Stahlmanschette 5 mit dem sie tragenden Rohr 1 gewährleistet. Auch bei starken Temperaturschwankungen, die ja aufgrund der unterschiedlichen Wärmeausdehnungskoeffizienten der Stahlmanschette 5 und der Rohrabschnitte 1 nicht unproblematisch sind, ist die Dichtigkeit nicht beeinträchtigt. Sowohl ein Wasserinnendruck als auch ein Wasseraußendruck von 5 bar und mehr ist möglich.To achieve a high-pressure-resistant connection of the sleeve 5 to the tube 1 carrying it, the sleeve 5 is provided in the region of its inner end 5a facing the tube section 1 with a radially inner circumferential profile 10, which is made of steel and welded to the inside of the sleeve 5 is. The welded connection 11 is preferably made liquid-tight. The circumferential profile 10 is cast in the reinforced concrete of the tube wall 4, whereby a type of labyrinth seal is formed, which ensures a watertight connection between the steel sleeve 5 and the tube 1 carrying it. Even with strong temperature fluctuations, which are not unproblematic due to the different thermal expansion coefficients of the steel sleeve 5 and the pipe sections 1, the tightness is not impaired. Both an internal water pressure and an external water pressure of 5 bar and more are possible.

Das umlaufende Profil 10 definiert eine radiale Ebene 9, auf der die Rohrachse 19 lotrecht steht. Das Profil 10 hat ferner eine radiale Höhe, die bevorzugt etwa 25% der Stärke der Rohrwandung 4 entspricht. Insbesondere erstreckt sich das Profil über eine radiale Tiefe von etwa 60mm.The circumferential profile 10 defines a radial plane 9 on which the tube axis 19 is perpendicular. The profile 10 also has a radial height, which preferably corresponds to approximately 25% of the thickness of the tube wall 4. In particular, the profile extends over a radial depth of approximately 60 mm.

Um die mit den Ankern 6 und dem umlaufenden Profil 10 vorgefertigten Stahlmanschetten 5 einfach handhaben zu können, ist vorgesehen, daß sowohl das innere Profil 10 als auch die Kopfanker 6 axial an der durch Stirnseite des inneren Endes 5a der Manschette bestimmten Ebene 8 enden. So stehen keine Teile über die stirnseitige Ebene 8 der Manschette vor, die beim Transport oder der Handhabung der vorgefertigten Manschette 8 stören könnten.In order to be able to handle the steel sleeves 5 prefabricated with the anchors 6 and the circumferential profile 10, it is provided that both the inner profile 10 and the head anchors 6 end axially at the plane 8 determined by the end face of the inner end 5a of the sleeve. So there are no parts above the frontal plane 8 of the cuff which could interfere with the transportation or handling of the prefabricated cuff 8.

Das umlaufende Profil 10 liegt bevorzugt nahe dem inneren Ende 5a der Manschette 5, während die Kopfanker 6 benachbart zum axialen Ende der Rohrwandung 4 innerhalb der Manschette 5 liegen.The circumferential profile 10 is preferably close to the inner end 5a of the sleeve 5, while the head anchors 6 lie adjacent to the axial end of the tube wall 4 within the sleeve 5.

In einer einfachen Ausführungsform kann das Profil ein radialer, umlaufender Steg oder auch ein I-Profil sein. Bevorzugt ist das Profil ein Winkelprofil, insbesondere ein L-Profil, so wie im Ausführungsbeispiel dargestellt. Der längere Schenkel 10a des L-Profils ragt radial in die Rohrwand 4, wobei der Schenkel 10a lotrecht auf der Innenfläche der Manschette 5 festgelegt ist. Der kurze Profilschenkel 10b ist am freien Ende des lotrechten Schenkels 10a angeordnet und ragt in Richtung auf das innere Ende 5a der Manschette; der kürzere Schenkel verläuft vorzugsweise parallel zur Rohrachse 19 und endet an der durch die Stirnseite des inneren Endes 5a bestimmten Ebene 8. Soll eine noch druckfestere Umläufigkeitsdichtung gewährleistet sein, kann das Profil 10 radial verlängert oder zweckmäßig in Form eines T-förmigen Profils ausgebildet sein.In a simple embodiment, the profile can be a radial, circumferential web or an I-profile. The profile is preferably an angle profile, in particular an L profile, as shown in the exemplary embodiment. The longer leg 10a of the L-profile projects radially into the tube wall 4, the leg 10a being fixed vertically on the inner surface of the sleeve 5. The short profile leg 10b is arranged at the free end of the vertical leg 10a and projects in the direction of the inner end 5a of the cuff; the shorter leg preferably runs parallel to the tube axis 19 and ends at the plane 8 defined by the end face of the inner end 5a. If an even more pressure-resistant circumferential seal is to be ensured, this can be done Profile 10 radially extended or expediently in the form of a T-shaped profile.

Die Rohrabschnitte können sowohl im offenen Graben als auch im Vortriebverfahren oder Vorpreßverfahren verlegt werden. Zur gleichmäßigen Druckverteilung der Vorschubkraft ist zwischen aufeinanderfolgenden Rohrabschnitten 1, 2 eine Ausgleichsscheibe, insbesondere eine Weichholzscheibe 15 zweckmäßig.The pipe sections can be laid in the open trench as well as in the jacking or pre-pressing process. For a uniform pressure distribution of the feed force, a compensating disk, in particular a softwood disk 15, is expedient between successive pipe sections 1, 2.
