Description

Die Erfindung betrifft ein Verfahren zum Vortreiben einer Tunnelstrecke mit über Stützrahmen abgestützen Vortriebs­messern sowie eine Messerschild-Vortriebsvorrichtung mit auf Stützrahmen abgestützen, über eine Druckeinrichtung vortreib­baren Vortriebsmessern, insbesondere zur Durchführung des Verfahrens.The invention relates to a method for driving a tunnel section with jacking knives supported by support frames, and to a blade shield driving device with jacking knives supported on support frames, which can be driven by a pressure device, in particular for carrying out the method.

Es ist bekannt, Vortriebsmesser über einen hydraulischen Zylinder vorzutreiben, welcher gegen einen Montagebogen ab­gestützt ist, der den zuletzt betonierten Ausgangsabschnitt eines Tunnels begrenzt, wobei die Kolbenstange des hydrau­lischen Zylinders lösbar in krallenartige Kupplungsteile an der Innenfläche des Vortriebsmessers angreift. Zum einen ist bei dieser aus der DE-OS 19 66 078 bekannten Vorrichtung von Nachteil, daß die großen Druckkräfte in die Betonaus­kleidung eingeleitet werden, und zum anderen ist die Hand­habung der sehr schweren hydraulischen Kolben-Zylinder-Einheit kraftaufwendig und gefährlich.It is known to propel jacking knives via a hydraulic cylinder which is supported against a mounting arch which delimits the last concreted exit section of a tunnel, the piston rod of the hydraulic cylinder releasably engaging in claw-like coupling parts on the inner surface of the jacking knife. On the one hand, it is disadvantageous in this device known from DE-OS 19 66 078 that the large compressive forces are introduced into the concrete lining, and on the other hand the handling of the very heavy hydraulic piston-cylinder unit is energy-intensive and dangerous.

Ferner ist eine Vorrichtung bekannt, bei welcher jeweils zwei Abstützrahmen untereinander verbunden sind, welche ähnlich eines selbstschreitenden Ausbaus, wie er im Bergbau bekannt ist, vorgesetzt werden können. Diese Vorrichtung ist technisch aufwendig gestaltet und nur begrenzt einsatzfähig.Furthermore, a device is known in which two supporting frames are connected to one another, which can be placed in a manner similar to a self-advancing expansion, as is known in mining. This device is technically complex and can only be used to a limited extent.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Vortreiben einer Tunnelstrecke sowie eine Vorrichtung zur Durchführung insbesondere dieses Verfahrens zu schaffen, welche schnell und einfach und mit weniger Kraftaufwand für die Be­dienungsmannschaft durchführbar bzw. handhabbar sind.The invention has for its object to provide a method for driving a tunnel route and an apparatus for performing this method in particular, which can be carried out or handled quickly and easily and with less effort by the operating team.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein Stützrahmen mit den Vortriebsmessern verbunden wird, und daß dieser Stützrahmen die beim Vortreiben eines Vortriebsmessers aufzubringende Druckkraft in die anderen Vortriebsmesser einleitet.This object is achieved in that a support frame is connected to the jacking knives and that this support frame introduces the pressure force to be applied when advancing a jacking knife into the other jacking knives.

Gemäß einer bevorzugten Ausgestaltung der Erfindung wird der hinterste Stützrahmen mit den Vortriebsmessern verbunden, nach dem Vortreiben der Messer wird die Verbindung mit dem hintersten Stützrahmen gelöst, danach wird der Stützrahmen entfernt, um als erster Stützrahmen im vorderen Bereich der Vortriebsmesser erneut angeordnet zu werden, und die Vor­triebsmesser werden mit dem dann hintersten Stützrahmen ver­bunden.According to a preferred embodiment of the invention, the rearmost support frame is connected to the jacking knives, After the knives have been driven forward, the connection to the rearmost support frame is released, then the support frame is removed in order to be arranged again as the first support frame in the front region of the jacking knives, and the jacking knives are connected to the rearmost support frame.

Bei dem erfindungsgemäßen Verfahren bilden alle Vortriebs­messer bis auf das vorzutreibende Vortriebsmesser mit einem der Stützrahmen, insbesondere mit dem in Vortriebsrichtung letzten Stützrahmen eine Einheit, so daß die Messer letztlich das Widerlager für das vorzutreibende Messer bilden. Dadurch wird verhindert, daß große Kräfte in die frische Betonaus­kleidung eingeleitet werden, oder daß zusätzliche Maßnahmen getroffen werden müssen, um ein ausreichend festes Widerlager zu bilden.In the method according to the invention, all jacking knives form a unit with one of the supporting frames, in particular with the last supporting frame in the forwarding direction, with the exception of the jacking knife to be driven, so that the knives ultimately form the abutment for the knife to be driven. This prevents large forces from being introduced into the fresh concrete lining or that additional measures have to be taken to form a sufficiently strong abutment.

Bei einer erfindungsgemäßen Vorrichtung insbesondere zur Durchführung des Verfahrens ist an jedem Vortriebsmesser eine Kolben-Zylinder-Einheit mit einem Ende angelenkt, an dem anderen Ende der Kolben-Zylinder-Einheit ist ein Abstütz­glied zum Eingriff an einem Stützrahmen angelenkt und es ist eine Einrichtung zum Verriegeln des Abstützgliedes an dem Stützrahmen vorgesehen.In a device according to the invention, in particular for carrying out the method, a piston-cylinder unit is articulated on one end of each tunneling knife, a support member for engagement on a support frame is articulated on the other end of the piston-cylinder unit, and it is a device for locking of the support member provided on the support frame.

Da an jedem Vortriebsmesser eine Kolben-Zylinder-Einheit vor­gesehen ist, kann die kräftezehrende und gefährliche Um­setzung der Kolben-Zylinder-Einheit von einem Vortriebsmesser an ein anderes Vortriebsmesser entfallen. Zum einen können längere Messer verwendet werden, und zum anderen arbeitet die erfindungsgemäße Vorrichtung schneller, so daß die Vor­triebsleistung erhöht werden kann.Since a piston-cylinder unit is provided on each jacking knife, the power-consuming and dangerous implementation of the piston-cylinder unit from one jacking knife to another jacking knife can be dispensed with. On the one hand, longer knives can be used, and on the other hand, the device according to the invention works faster, so that the driving power can be increased.

Gemäß einer bevorzugten Ausführungsform weist das Abstütz­glied einen hakenartigen Ansatz zum Untergreifen der Vorder­kante eines Stützrahmens auf, und am hinteren Ende des Ab­stützgliedes ist ein befestigbarer, die Hinterkante des Stützrahmens untergreifender Haken vorgesehen. Nach Anlegen des Abstützgliedes an dem Stützrahmen und Sichern des Hakens am hinterem Ende des Abstützgliedes ist eine druck- und zug­feste Verbindung der Kolben-Zylinder-Einheit an dem Stütz­rahmen geschaffen. Die Einleitung der Druckkräfte muß erfolgen, wenn die Kolben-Zylinder-Einheit ausgefahren wird, um das Vortriebsmesser vorzutreiben. Zugkräfte treten dabei bei den übrigen Messern auf, da diese den Stützrahmen an einer Ausweichbewegung nach hinten hindern.According to a preferred embodiment, the support member has a hook-like extension for reaching under the front edge of a support frame, and at the rear end of the support member there is a fastenable hook which engages under the rear edge of the support frame. After creation the support member on the support frame and securing the hook at the rear end of the support member a pressure and tensile connection of the piston-cylinder unit is created on the support frame. The pressure forces must be applied when the piston-cylinder unit is extended to advance the jacking knife. Tensile forces occur with the other knives, since these prevent the support frame from moving backwards.

Gemäß einer bevorzugten Ausführungsform ist das Abstützglied doppelwandig ausgebildet, das Ende des Kolbens der Kolben-­Zylinder-Einheit ist zwischen den Wänden angelenkt und es sind zwei über Keile festlegbare Haken vorgesehen. Dabei ist vorzugsweise zwischen den Wänden ein nach hinten heraus­stehendes T-förmiges Element zur Aufnahme der Haken und Keile befestigt, so daß eine Schnellverriegelung des Abstützgliedes an dem Stützrahmen möglich ist.According to a preferred embodiment, the support member is double-walled, the end of the piston of the piston-cylinder unit is articulated between the walls and two hooks which can be fixed by means of wedges are provided. In this case, a T-shaped element protruding towards the rear for receiving the hooks and wedges is preferably fastened between the walls, so that a quick locking of the support member on the support frame is possible.

Zur Erhöhung der Festigkeit sind zwischen den Wänden des Abstützelementes Aussteifungen angeordnet.To increase the strength, stiffeners are arranged between the walls of the support element.

Fig. 1 zeigt ein Vortriebsmesser 10, das Teil einer aus einer Vielzahl von Vortriebsmessern bestehenden Messerschild-Vor­triebsvorrichtung ist. Das Vortriebsmesser 10 besteht aus einer oberen Wand 12, einer unteren Wand 14 und Seitenwänden 16, 18. Am vorderen Ende ist das Messer 10 mit einer Messer­spitze 20 versehen. Das Vortriebsmesser ruht auf Stützrahmen 22, 24, 26 auf. Der hintere Abschnitt 28 des Messers 10, der mit dem vorderen, stärkeren Abschnitt 30 über ein Gelenk 32 verbunden ist, dient während der Einbringung einer Beton­auskleidung 34 als Schalung.1 shows a jacking knife 10 which is part of a knife shield jacking device consisting of a plurality of jacking knives. The jacking knife 10 consists of an upper wall 12, a lower wall 14 and side walls 16, 18. At the front end, the knife 10 is provided with a knife tip 20. The jacking knife rests on support frames 22, 24, 26. The rear section 28 of the knife 10, the connected to the front, thicker section 30 via a joint 32 serves as formwork during the installation of a concrete lining 34.

Hinter der Spitze 20 ist ein Lagerbock 36 angeordnet, an welchem über ein Schwenklager 38 ein Zylinder 40 einer Kolben-Zylinder-Einheit angelenkt ist. Die Kolben-Zylinder-Einheit weist einen nach hinten gerichteten Kolben 42 auf, welcher an dem nach hinten vorstehenden freien Ende mit einem Gelenk­zapfen 44 versehen ist, an welchem ein Abstützglied 46 ange­lenkt ist. Das Abstützglied 46 dient der Verriegelung des Kolbens 42 in Druck- und Zugrichtung an dem hintersten Stützrahmen 26.Arranged behind the tip 20 is a bearing block 36, to which a cylinder 40 of a piston-cylinder unit is articulated via a pivot bearing 38. The piston-cylinder unit has a piston 42 directed towards the rear, which is provided at the free end projecting towards the rear with a pivot pin 44 to which a support member 46 is articulated. The support member 46 serves to lock the piston 42 in the pushing and pulling direction on the rearmost support frame 26.

Die genaue Ausbildung und die Wirkungsweise des Abstütz­gliedes 46 wird insbesondere anhand der Fig. 3 bis 5 näher erläutert.The exact design and the mode of operation of the support member 46 will be explained in more detail in particular with reference to FIGS. 3 to 5.

Das Abstützglied 46 besteht aus zwei Seitenwänden 48, 50 die über Distanz- und Versteifungselemente 52 und 54 miteinander verbunden sind. Die Wände 48 und 50 nehmen den Lagerzapfen 44 auf. Die Wände 48 und 50 sind an der Unterseite mit haken­förmigen Ansätzen 56, 58 versehen, welche die Vorderkante 60 des Stützrahmens 26 untergreifen. Damit ist das Abstütz­glied 46 in Druckrichtung der Kolben-Zylinder-Einheit 40, 42 an dem Stützrahmen 26 verriegelt.The support member 46 consists of two side walls 48, 50 which are connected to one another via spacing and stiffening elements 52 and 54. The walls 48 and 50 receive the journal 44. The walls 48 and 50 are provided on the underside with hook-shaped projections 56, 58 which engage under the front edge 60 of the support frame 26. The support member 46 is thus locked in the pressure direction of the piston-cylinder unit 40, 42 on the support frame 26.

Die Verriegelung des Abstützgliedes 46 in Zugrichtung an dem Stützrahmen 26 erfolgt über Haken 62, 64, welche die Hinterkante des Stützrahmens 26 untergreifen. Die Haken 62 und 64 werden an dem Abstützglied 46 gesichert über Keile 66, 68, welche gegen den Querschenkel 70 eines T-förmigen Elementes 72 anliegen, das mit seinem Längsschenkel 74 zwischen den Wänden 48, 50 des Abstützgliedes 46 befestigt ist. Nachdem das Abstützglied mit seinen Haken 56 die Vorder­kante des Stützrahmens 26 untergriffen haben, können die Haken 62, 64 seitlich eingebracht werden, wonach sie über die Keile 66, 68 fixiert werden.The support member 46 is locked in the pulling direction on the support frame 26 via hooks 62, 64 which engage under the rear edge of the support frame 26. The hooks 62 and 64 are secured to the support member 46 by means of wedges 66, 68 which bear against the cross leg 70 of a T-shaped element 72 which is fastened with its longitudinal leg 74 between the walls 48, 50 of the support member 46. After the support member with its hooks 56 has reached under the front edge of the support frame 26, the hooks 62, 64 can be inserted laterally, after which they are fixed in place via the wedges 66, 68.

Die Durchführung des Verfahrens und die Wirkungsweise der Vorrichtung ist folgendermaßen: Alle mit ihrer Messerspitze 20 in einer Ebene liegenden und auf den Stützrahmen 22, 24, 26 aufliegenden Messer 10 werden mit ihrem Abstützglied 46 an dem hintersten Stützrahmen 26 verriegelt. Die Verschiebung des Abstützgliedes 46, an welchem die hinteren Haken 62, 64 und die Keile 66, 68 entfernt sind, erfolgt über die Kolben-­Zylinder-Einheit 40, 42, die über eine Leitung 76 mit Druck beaufschlagt oder entlastet wird. Sobald die Haken 56, 58 die Vorderkante des Stützrahmens 26 untergreifen, werden die Haken 62, 64 mit den Keilen 66, 68 an dem Abstützglied 46 be­festigt. Damit liegt eine feste Verbindung zwischen dem Ab­stützglied 46 und dem Stützrahmen 26 vor.The implementation of the method and the mode of operation of the device are as follows: All the knives 10 lying with their knife tip 20 in one plane and resting on the support frame 22, 24, 26 are locked with their support member 46 on the rearmost support frame 26. The displacement of the support member 46, on which the rear hooks 62, 64 and the wedges 66, 68 are removed, takes place via the piston-cylinder unit 40, 42, which is pressurized or relieved via a line 76. As soon as the hooks 56, 58 engage under the front edge of the support frame 26, the hooks 62, 64 are fastened to the support member 46 with the wedges 66, 68. There is thus a fixed connection between the support member 46 and the support frame 26.

Wenn alle Abstützglieder auf diese Weise mit dem Stütz­rahmen 26 verriegelt sind, werden nacheinander alle Messer 10 um die gewünschte Strecke vorgetrieben. Die von dem je­weils vorzutreibenden Messer ausgeübte Druckkraft, die durch Beaufschlagung des Kolbens 42 in dem Zylinder 40 in das Ab­stützglied 46 übertragen wird, wird über den Stützrahmen 26 in die benachbarten Messer eingeleitet, welche damit in­direkt als Widerlager für das vorzutreibende Messer dienen.When all the support members are locked in this way with the support frame 26, all the knives 10 are driven one after the other by the desired distance. The pressure force exerted by the knife to be driven in each case, which is transmitted into the support member 46 by acting on the piston 42 in the cylinder 40, is introduced via the support frame 26 into the neighboring knives, which thus serve indirectly as an abutment for the knife to be driven.

Sobald alle Messer vorgetrieben sind und sich die Messer­spitzen 20 wieder in einer Ebene befinden, werden von allen Abstützgliedern 46 die Haken 62, 64 abgenommen. Jetzt können durch Einfahren des Kolbens 42 die Abstützglieder von dem hinteren Stützrahmen 26 entfernt werden. Nachdem dies bei sämtlichen Messern erfolgt ist, wird der Stützrahmen 26 abgenommen und als erster Stützrahmen vor dem Stütz­rahmen 22 angeordnet. Die Abstützglieder 46 werden jetzt soweit in Richtung der Messerspitze durch Einfahren des Kolbens 42 gezogen, bis die Anstützglieder 46 an dem Stützrahmen 24 verriegelt werden können. Wenn sämtliche Abstützglieder 46 die Vorderkante des Stützrahmens 24 untergreifen und die die Hinterkante untergreifenden Haken angeordnet sind, kann ein erneuter Vortrieb der Vortriebs­messer nacheinander vorgenommen werden.As soon as all the knives have been advanced and the knife tips 20 are again in one plane, the hooks 62, 64 are removed from all the support members 46. The support members can now be removed from the rear support frame 26 by retracting the piston 42. After this has been done with all knives, the support frame 26 is removed and arranged as the first support frame in front of the support frame 22. The support members 46 are now pulled in the direction of the knife tip by retracting the piston 42 until the support members 46 can be locked on the support frame 24. When all the support members 46 reach under the front edge of the support frame 24 and the hooks under the rear edge are arranged, the jacking knives can be driven again one after the other.
