Abstract

During tunnel driving with driving shields, reaction forces develop which as a rule are diverted to the end face of the tunnel lining. In the case of cast-in-situ tunnel lining, the shield circumferential friction and the pressure of the newly placed concrete on the end formwork (4) are not adequate to absorb the reaction forces occurring, which are therefore passed via the inner formwork (7) into the already hardened concrete in the rear area of the formwork. In order to shift the formwork rings (8) in an unimpeded manner by means of the erector (18) above the travelling carrier (19) after completion of a formwork section, the space inside the inner formwork (7) must remain free. Therefore, while a formwork ring (10) is being shifted from the end to the start of the area cased by the inner formwork (7), the reaction forces of the shield (1) are passed into the formwork by means of longitudinally adjustable supports (16) in the shield tail (15) via the brackets (17) arranged close to the end face (11) on the outer surface of the frontmost formwork ring (9). <IMAGE>

Description

Die Erfindung betrifft eine Abstützung für einen Vortriebsschild, wie sie im Oberbegriff des Anspruchs 1 beschrieben ist.The invention relates to a support for a jacking shield, as described in the preamble of claim 1.

Beim Tunnelvortrieb mit Vortriebschilden entstehen als Reaktionen der Vortriebskräfte und, sofern zur Stützung der Ortsbrust in der Abbaukammer ein Druckmedium verwendet wird, aus dem Stützdruck auf die Rückwand der Abbaukammer nach rückwärts gerichtete Reaktionskräfte, die in der Regel über die rückwärtige fertiggestellte Tunnelwandung wieder in das den Tunnel umgebende Gebirge abgeleitet werden. Aus Gründen der Wirtschaftlichkeit werden die Reaktionskräfte, wo dies möglich ist - z. B. beim Tübbingausbau -, unmittelbar im Schildschwanz auf die Auskleidung abgegeben.When tunneling with tunneling shields, reactions of the tunneling forces and, if a pressure medium is used to support the working face in the excavation chamber, backward reaction forces arise from the support pressure on the rear wall of the excavation chamber, which as a rule via the completed tunnel wall back into the Mountains surrounding tunnels can be derived. For reasons of economy, the reaction forces where possible - e.g. B. in segment lining - directly in the shield tail on the lining.

Bei Auskleidungen in Ortbeton können die Reaktionskräfte nicht unmittelbar an die Auskleidung abgegeben werden. Die Pressung des frisch eingebrachten Betons auf die Stirnschalung im Ringraum ist in der Regel nicht ausreichend, um die beim Vortrieb entstehenden Reaktionskräfte aufzunehmen. Sie werden deshalb an der Stirnseite der Schalung eingeleitet und von der Schalung durch Mantelreibung an den bereits erhärteten Beton im rückwärtigen geschalten Bereich abgegeben.In the case of linings in in-situ concrete, the reaction forces cannot be transferred directly to the lining. The pressure of the freshly poured concrete on the forehead formwork in the annular space is generally not sufficient to absorb the reaction forces that arise during driving. They are therefore introduced at the front of the formwork and released from the formwork by skin friction to the already hardened concrete in the rear, switched area.

Beim Umsetzen der Schalung vom Ende des geschalten Bereichs an den Anfang im Zuge des Vortriebs nach einem Vortriebsabschnitt müssen mindestens in dem für den Einbau des umzusetzenden Schalungsteils freizumachenden Bereich die sich an die Schalung abstützenden Vortriebspressen zurückgefahren werden. Der Schild ist für die Zeitspanne der Umsetzung dieses Schalungsteils minde­stens in Abschnitten des Schildumfangs nicht durch Vortriebs­pressen abgestützt.When moving the formwork from the end of the switched area to the beginning in the course of tunneling after a tunneling section, the jacking presses supported on the formwork must be moved back at least in the area to be cleared for the installation of the formwork part to be moved. The shield is not supported by jacking presses for the period of implementation of this formwork part, at least in sections of the shield circumference.

Aus Wirtschaftlichkeitsgründen hat es sich beim Ortbetonausbau durchgesetzt, vollständige Schalungsringe umzusetzen. Dem Schild fehlt dann in der Zeitspanne des Umsetzens eines Ringes jede Ab­stützung durch die Vortriebspressen. Zur zeitweiligen Abstützung beim Umsetzen eines Schalungsringes ist es aus der DE OS 36 28 028 bekannt, als Hilfsabstützung den ohnehin vorhandenen Fahrträger zu verwenden, der vorn im Schild und rückwärtig im ausgeschalten erhärteten Ausbaubeton abgestützt ist. Dieser Fahrträger wird, um ein Rücklaufen des Schildes zu verhin­dern, mit Hilfe ausklappbarer Spreizpressen oder mit Hilfe von Seilzügen an der Schalung im rückwärtigen Bereich des bereits verfestigten Betons verankert.For reasons of economy, it has prevailed when installing in-situ concrete to implement complete formwork rings. The shield then lacks any support from the jacking presses in the period of moving a ring. For temporary support when moving a formwork ring, it is known from DE OS 36 28 028 to use as an auxiliary support the already existing driving beam, which is supported at the front in the shield and at the rear in the hardened expansion concrete when switched off. In order to prevent the shield from running back, this driving beam is anchored to the formwork in the rear area of the already solidified concrete with the aid of fold-out spreading presses or with the aid of cable pulls.

Als nachteilig bei dieser bisher verwendeten Hilfsstützung wird angesehen, daß die Anschlüsse zur Verankerung des Fahrträgers an der Schalung bei jedem Umsetzen eines Schalungsrings für die Durchfahrt des Erektors mit dem zusammengeklappten Schalungsring gelöst werden müssen. Weiterhin erzeugen diese in begrenzter Zahl auf der Schalung angeschlossenen unhandlichen Abspannungen der Hilfsabstützung Kräfte, die Ursache für eine sehr ungünstige Beanspruchung der Schalung sind, wobei der vordere Schalungsabschnitt während der Umsteifung völlig von Längskräften entlastet wird.A disadvantage of this previously used auxiliary support is that the connections for anchoring the carrier to the formwork have to be loosened each time a formwork ring is moved through the erector with the folded formwork ring. Furthermore, these limited number of unwieldy braces of the auxiliary support connected to the formwork generate forces which are the cause of a very unfavorable load on the formwork, the front formwork section being completely relieved of longitudinal forces during the reinforcement.

Die Erfindung will eine Abstützung für einen Vortriebsschild der gattungsgemäßen Art derart weiterbilden, daß beim Setzen eines neuen Schalungsringes für den Ortbetonausbau der Vortriebsschild sicher an den Schalungsringen abstützbar ist, der Kräfteverlauf in der Schalung und im Ortbetonausbau während der Hilfsabstützung gegenüber dem Zustand des Vortriebs nahezu unverändert bleibt.The invention intends to further develop a support for a jacking shield of the generic type such that when a new formwork ring for in-situ concrete expansion is set, the driving shield can be securely supported on the formwork rings, the course of forces in the formwork and in-situ concrete expansion during the auxiliary support is virtually unchanged from the state of the advance remains.

Die Aufgabe wird durch die im kennzeichnenden Teil des An­spruchs 1 beschriebene Abstützung gelöst. Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.The object is achieved by the support described in the characterizing part of claim 1. Embodiments of the invention are described in the subclaims.

Die Hilfsabstützung des Schildes während des Umsetzens der Scha­lungsringe wird durch konzentrisch auf der Innenseite des Mantels angeordnete längenverstellbare Stützeinheiten bewirkt. Beispiels­weise als hydraulische Pressen ausgebildet, sind diese Stütz­einheiten einfache im Tunnelbau übliche Elemente, die vollmecha­nisch betätigbar sind. Die an gesonderten Knaggen auf der Außenfläche der Schalung außerhalb der Stoßflächen der einzelnen Schalungsringe Stützeinheiten erfordern keine weiteren zusätzlichen Handgriffe an der Schalung oder am Fahrträger, wenn ein Schalungsring umgesetzt werden soll. Die Bewegungsfreiheit des Erektors auf dem Fahrträger wird durch keinerlei Hilfsvorrichtungen zur Abstützung des Schildes eingeschränkt. Die Einleitung der Kräfte der Hilfsabstützung nahe der Stirnseite der Schalung verändert die Einleitung der Reaktionskräfte des Schildes gegenüber dem Vortriebszustand nur unwesentlich. Der Einbau der erfindungs­gemäßen Stützeinheiten erfordert eine geringfügige Verlängerung des Schwanzteiles des Schildes sowie eine Schildschwanzdichtung mit vergrößertem Arbeitsbereich, der sich aus der für das Übergleiten der Knaggen notwendigen Verbreiterung des Ringspaltes ergibt.The auxiliary support of the shield during the relocation of the formwork rings is brought about by length-adjustable support units arranged concentrically on the inside of the jacket. For example, designed as hydraulic presses, these support units are simple elements that are common in tunnel construction and can be actuated fully mechanically. The support units on separate lugs on the outer surface of the formwork outside the abutting surfaces of the individual formwork rings do not require any additional handles on the formwork or on the traveling girder if a formwork ring is to be moved. The freedom of movement of the erector on the carriage is not restricted by any auxiliary devices for supporting the shield. The introduction of the forces of the auxiliary support near the face of the formwork changes the introduction of the reaction forces of the shield only insignificantly compared to the state of propulsion. The installation of the support units according to the invention requires a slight extension of the tail part of the shield and a shield tail seal with an enlarged working area, which results from the widening of the annular gap necessary for the sliding over of the lugs.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnungen näher erläutert. Es zeigen:

  • Fig. 1 einen vertikalen Schnitt in Längsachse des Schildes mit Stützeinheiten nach Anspruch 2
  • Fig. 2 einen Querschnitt durch den Schild im Bereich der Stützeinheiten nach Anspruch 2
  • Fig. 3 eine erfindungsgemäße Stützeinheit nach Anspruch 2.
The invention is explained in more detail below using an exemplary embodiment with reference to the drawings. Show it:
  • Fig. 1 is a vertical section in the longitudinal axis of the shield with support units according to claim 2
  • 2 shows a cross section through the shield in the area of the support units according to claim 2
  • 3 shows a support unit according to the invention as claimed in claim 2.

Bei einem Tunnelvortrieb wird mit einem Schild 1 eine Tunnelröhre 2 aufgefahren. Die Auskleidung 3 der Tunnelröhre 2 besteht aus Ortbeton, der durch Öffnungen der Stirnschalung 4 in den Ringspalt 5, den das Ausbruchprofil 6 und die Außenfläche der Innenschalung 7 miteinander bilden, eingepreßt wird. Die Innenschalung 7 baut sich aus Schalungsringen 8,9 auf. Beim Vortrieb stützen sich die Vortriebspressen 12 vorn gegen den Schild 1 und rückwärtig über einen Druckring 13 auf die Stirnfläche 11 des vordersten Schalungsrings 9 ab. Die Vortriebspressen 12 übertragen die Reaktionskräfte aus dem Vortrieb und einem eventuellen Überdruck in der Abbaukammer 14 auf die Innenschalung 7.During tunneling, a tunnel tube 2 is opened with a shield 1. The lining 3 of the tunnel tube 2 consists of in-situ concrete, which is pressed through openings in the front formwork 4 into the annular gap 5, which the breakout profile 6 and the outer surface of the inner formwork 7 form together. The inner formwork 7 is built up from formwork rings 8.9. When driving, the jacking presses 12 are supported at the front against the shield 1 and at the rear via a pressure ring 13 on the end face 11 of the foremost formwork ring 9. The jacking presses 12 transmit the reaction forces from the jacking and any excess pressure in the excavation chamber 14 to the inner formwork 7.

Nach Beendigung eines Vortriebsabschnitts, der etwa die Länge einer Schalungsringbreite besitzt, werden die Vortriebspressen 12 mit dem Druckring 13 eingezogen, um Platz zu machen zum Ein­setzen eines vom rückwärtigen Ende der Innenschalung 7 abge­bauten Schalungsrings 10 vor dem zuletzt eingebauten Schalungsring 9 der Innenschalung.After completion of a tunneling section, which has approximately the length of a formwork ring width, the jacking presses 12 are pulled in with the pressure ring 13 in order to make room for inserting a formwork ring 10 which has been removed from the rear end of the inner formwork 7 in front of the last installed formwork ring 9 of the inner formwork.

Damit der Schild 1 in der Zeit des Umsetzens des Schalungsrings 10 nicht ungestützt bleibt und beim Fehlen einer Stützung möglicher­weise zurückgedrückt werden kann, werden konzentrisch am Schild­schwanz 15 auf der Innenseite des Schildmantels angeschlagene - im Beispiel durch hydraulische Pressen - längenverstellbare Stützeinheiten 16 ausgefahren, die sich rückwärtig auf die Knaggen 17 des zuletzt eingebauten Schalungsrings 9 abstützen. Knaggen 17 sind auf der Außenfläche der Innenschalung 7 nahe der vorderen Stirnfläche jedes Schalungsrings angebracht. Durch die Anordnung der Knaggen 17 außerhalb des Außendurchmessers der Stirnfläche 11 der Schalungsringe kann der Schalungsring 10 unbehindert von den Stützeinheiten 16 von dem auf dem Fahrträger 19 bewegbaren Erektor 18 am hinteren Ende der Innenschalung 7 abgebaut, zum vorderen Ende der Innenschalung 7 transportiert und wieder eingebaut werden. Nach Beendigung des Umsetzvorgangs werden die Vortriebspressen 12 mit dem Druckring 13 gegen die Stirnfläche 11 des neu eingebauten Schalungsrings angepreßt und ein neuer Vortriebsabschnitt kann beginnen.So that the shield 1 does not remain unsupported during the implementation of the formwork ring 10 and can possibly be pushed back in the absence of a support, length-adjustable support units 16 which are struck concentrically on the shield tail 15 on the inside of the shield shell, in the example by hydraulic presses, are extended Support backwards on the lugs 17 of the last installed formwork ring 9. Knaggen 17 are attached to the outer surface of the inner formwork 7 near the front end face of each formwork ring. Due to the arrangement of the lugs 17 outside the outer diameter of the end face 11 of the formwork rings, the formwork ring 10 can be dismantled unhindered by the support units 16 from the erector 18 movable on the driving beam 19 at the rear end of the inner formwork 7, transported to the front end of the inner formwork 7 and reinstalled will. After completion of the transfer process, the jacking presses 12 are pressed with the pressure ring 13 against the end face 11 of the newly installed formwork ring and a new jacking section can begin.

Nachdem die Vortriebspressen 12 die Abstützung des Schildes wieder übernommen haben, können die Abstützungen 16 zurückge­zogen werden. Während die Abstützungen 16 in Funktion sind, drücken geeignete Vorrichtungen - im Beispiel ein hydraulischer Zylinder 21 - den Kopf 20 der Abstützung 16 gegen die Außen­fläche der Innenschalung 7.After the jacking presses 12 have taken over the support of the shield again, the supports 16 can be withdrawn. While the supports 16 are in operation, suitable devices - in the example a hydraulic cylinder 21 - press the head 20 of the support 16 against the outer surface of the inner formwork 7.

Beim weiteren Vortrieb müssen der Schildschwanz 15 mit der Stirn­schalung 4 und die Schildschwanzdichtung 22 über die Knaggen 17 hinweggleiten. Die Knaggen 17 werden daher zweckmäßig nach rückwärts gegen die Schalungsfläche hin mit geringer Steigung auslaufend und der Ringspalt 23 zwischen der Stirnschalung 4 und der Außenfläche der Innenschalung 7 entsprechend breiter ausge­bildet. Zum Verschließen des Ringspalts 23 muß eine Schild­schwanzdichtung 22 mit entsprechend vergrößertem Arbeitsbereich vorgesehen werden.During further driving, the tail 15 with the front formwork 4 and the tail seal 22 must slide over the lugs 17. The lugs 17 are therefore expediently tapering backwards against the formwork surface with a slight slope and the annular gap 23 between the end formwork 4 and the outer surface of the inner formwork 7 is correspondingly wider. To close the annular gap 23, a shield tail seal 22 with a correspondingly enlarged working area must be provided.
