Description

Die Erfindung bezieht sich auf ein Verfahren zum Tunnelvortrieb unter Verwendung einer Schildvortriebsmaschine, bei welcher der Abbauraum gegenüber der Schildkonstruktion mittels einer Druckglocke abgedichtet und unter gegenüber dem Raum innerhalb der Schildkonstruktion höheren Druck gesetzt wird, sowie auf eine Vorrichtung zur Durchführung dieses Verfahrens, mit einem Abbauwerkzeug, insbesondere Schneidrad, und einer das Abbauwerkzeug dichtend umgebenden Druckglocke.The invention relates to a method for tunneling using a shield tunneling machine, in which the excavation space is sealed off from the shield construction by means of a pressure bell and under higher pressure than the space inside the shield construction, and to a device for carrying out this method, with a dismantling tool , in particular the cutting wheel, and a pressure bell that surrounds the removal tool in a sealing manner.

Aus der DE-A-35 14 563 ist eine Tunnelvortriebsmaschine bekanntgeworden, welche ein Schneidrad mit sich drehender Schürfscheibe und eine Fördereinrichtung aufweist, die das abgebaute Material zur Spülkammer einer hydraulischen Abfördereinrichtung transportiert. Die Schürfscheibe weist gleichmäßig verteilte Schneidbalken auf, welchen benachbart verschließbare Öffnungen vorgesehen sind, welche in Sektorkammern für das abgebaute Material münden. Durch ein gezieltes Verschließen der Öffnungen in der Schürfscheibe wird über den gesteuerten Austrag des Materials durch das Schneidrad ein Stützdruck auf die Ortsbrust erzeugt.A tunnel boring machine has become known from DE-A-35 14 563, which has a cutting wheel with a rotating scraper disc and a conveying device which transports the mined material to the rinsing chamber of a hydraulic conveying device. The scraper disc has evenly distributed cutting bars, which are provided with closable openings which open into sector chambers for the mined material. Through a targeted closing of the openings in the scraper disc, a support pressure on the face is generated by the controlled discharge of the material through the cutting wheel.

Aus der DE-OS 2 327 816 ist eine Vorrichtung und ein Verfahren zum Bodenabtransport aus der Druckkammer eines Tunnelvortriebsschildes bekanntgeworden. Bei der zu diesem Zweck bekannten Einrichtung ist hinter den Abbauwerkzeugen eine druckfeste dichtende Wand im Inneren der Schildkonstruktion errichtet und es wird eine Druckkammer ausgebildet, welche räumlich von dem Raum getrennt ist, in welchem sich Bedienungspersonal aufhält. Die Druckkammer wird in der Regel mit Druckluft gefüllt, um das je nach geologischer Formation auftretende Wasser zurückzuhalten.From DE-OS 2 327 816 a device and a method for the removal of soil from the pressure chamber of a tunnel driving shield have become known. In the device known for this purpose, a pressure-resistant sealing wall is built inside the shield construction behind the dismantling tools and a pressure chamber is formed which is spatially separated from the room in which operating personnel are located. The pressure chamber is usually filled with compressed air in order to retain the water that occurs depending on the geological formation.

Aus der DE-PS 35 33 425 ist eine Stützflüssigkeitsdruckregelung für eine Schildvortriebsmaschine bekanntgeworden, wobei die mit Stützflüssigkeit gefüllte Abbaukammer von einer den Maschinenquerschnitt durchsetzenden Trennwand vom nicht unter Überdruck stehenden Tunnel abgedichtet ist. Zur Beherrschung der aus der Inkompressibilität der Stützflüssigkeit resultierenden Probleme ist für die Abstützung eine Federanordnung vorgesehen, wodurch auf einen Stützflüssigkeitsdruckbehälter verzichtet werden kann. Bei der bekannten Ausbildung ist dabei lediglich eine Verschiebung in Maschinenlängsrichtung vorgesehen.From DE-PS 35 33 425 a support fluid pressure control for a shield tunneling machine has become known, the extraction chamber filled with support fluid from one the partition through the machine cross-section is sealed by the tunnel, which is not under pressure. To control the problems resulting from the incompressibility of the support fluid, a spring arrangement is provided for the support, as a result of which a support fluid pressure container can be dispensed with. In the known design, only a shift in the machine longitudinal direction is provided.

Es sind auch bereits Erddruck-Ausgleichsschilde bekannt, bei denen der Erddruck jeweils durch gesonderte Meßgeräte erfaßt wird. Durch den Zutritt von frischgelöstem Boden ist allerdings ein Wechsel in der Materialdichte unvermeidbar. Der Einsatz der bekannten Erddruck-Ausgleichsschilde ist aus diesem Grund zumeist auf weiche, breiige Böden im Grundwasser begrenzt. Bei einer bekannten Einrichtung dieser Art wird das abgebaute Erdreich in einer Fördertrommel bzw. Schnecke soweit verdichtet, daß das Material eine undurchlässige Barriere bildet, die die Ortsbrust stützen und Grundwasser zurückhalten kann. In derartigen Einrichtungen werden Druckmeßdosen angeordnet, die sowohl im Druckraum als auch im Bereich der Transportschnecke angeordnet sein können, wodurch die Möglichkeit geschaffen werden soll, den Bodenabzug aus der Schnecke den Druckverhältnissen entsprechend zu steuern. Derartige Druckmeßdosen können aber nur eine kleine, örtlich begrenzte Fläche erfassen, so daß mit Rücksicht auf die über die Ortsbrust unterschiedliche Materialdichte mit relativ großer Unsicherheit im Bezug auf die tatsächlichen Druckverhältnisse an der Abbaufläche gerechnet werden muß.Earth pressure compensation shields are also known, in which the earth pressure is measured by separate measuring devices. However, a change in material density is unavoidable due to the access of freshly dissolved soil. For this reason, the use of the known earth pressure compensation shields is mostly limited to soft, mushy soils in the groundwater. In a known device of this type, the mined soil is compacted in a conveyor drum or screw to such an extent that the material forms an impermeable barrier which can support the working face and retain groundwater. In such devices pressure transducers are arranged, which can be arranged both in the pressure chamber and in the area of the screw conveyor, whereby the possibility is to be created to control the extraction of soil from the screw according to the pressure conditions. However, such pressure transducers can only cover a small, locally limited area, so that in view of the different material densities across the working face, relatively large uncertainties with regard to the actual pressure conditions on the mining area must be expected.

Die Erfindung zielt nun darauf ab, ein Verfahren der eingangs genannten Art zu schaffen, welches es ermöglicht, die tatsächlichen Druckverhältnisse an der Ortsbrust exakter zu erfassen und insbesondere dann noch eine sinnvolle Steuerung ermöglicht, wenn über die Ortsbrust größere Schwankungen in der Materialdichte und in den Druckverhältnissen auftreten. Auf die Weise sollen Setzungen und andere plötzlich auftretende Probleme beim Vortrieb rechtzeitig erkennbar werden und die Möglichkeit geschaffen werden, rechtzeitig Gegenmaßnahmen einzuleiten.The invention now aims to provide a method of the type mentioned, which makes it possible to detect the actual pressure conditions on the working face more precisely and, in particular, enables a sensible control if there are greater fluctuations in the material density and in the working face Pressure conditions occur. In this way, settlements and other sudden occurrences are said Problems in tunneling become recognizable in good time and the opportunity is created to take countermeasures in good time.

Zur Lösung dieser Aufgabe besteht das erfindungsgemäße Verfahren im wesentlichen darin, daS der Druck im Abbauraum über eine in Längsrichtung der Schildkonstruktion dichtend verschiebliche und gegenüber der Längsrichtung der Schildkonstruktion schwenkbare dichtende Druckglocke unmittelbar auf das Material im Abbauraum übertragen wird, und daß die Druckglocke mittels eines einstellbaren und/oder regelbaren Antriebes gegen das Material im Abbauraum gepreßt wird. Dadurch, daß der Druck im Abbauraum über eine verschiebliche und schwenkbare dichtende Druckglocke unmittelbar auf das Material im Abbauraum übertragen werden kann, wird die Möglichkeit geschaffen, gezielt den Unterschieden in der Konsistenz des abgebauten Materials in unterschiedlichen Höhenlagen Rechnung zu tragen. Durch die verschiebliche und gleichzeitig schwenkbare, dichtende Druckglocke wird es möglich, über die gesamte Höhe der Vortriebsmaschine einen konstanten Druck aufrechtzuerhalten. Da der Druck im Abbauraum über die Druckglocke unmittelbar auf das Material eingebracht wird, werden Verzerrungen vermieden, welche bei der Verwendung von Stützflüssigkeiten im Abbauraum auftreten, da bei der Verwendung von Stützflüssigkeiten naturgemäß der hydrostatische Druck im Bereich der Sohle größer als im Bereich der Firste des Tunnels ist.To achieve this object, the method according to the invention essentially consists in that the pressure in the excavation space is transferred directly to the material in the excavation space via a sealing pressure bell that can be moved in the longitudinal direction of the shield construction and swivels with respect to the longitudinal direction of the shield construction, and that the pressure bell is adjustable by means of an adjustable one and / or controllable drive is pressed against the material in the excavation space. The fact that the pressure in the excavation space can be transferred directly to the material in the excavation space via a displaceable and pivotable sealing pressure bell, the possibility is created to specifically take into account the differences in the consistency of the degraded material at different altitudes. The movable and swiveling, sealing pressure bell makes it possible to maintain a constant pressure over the entire height of the tunneling machine. Since the pressure in the excavation space is introduced directly onto the material via the pressure bell, distortions are avoided which occur when using support fluids in the excavation space, since when using support fluids the hydrostatic pressure in the area of the sole is naturally greater than in the area of the ridges of the Is tunnels.

Gemäß einer bevorzugten Ausführungsform wird der Antrieb der Abbauwerkzeuge in der Druckglocke gelagert und die Rotationsachse dieses Antriebes gemeinsam mit der Druckglocke verschwenkt, wodurch in jeder Schwenklage der Druckglocke entsprechend dem erforderlichen Stützdruck eine gleichmäßige Auslastung und damit eine hohe, angepaßte, gleichbleibende Abbauleistung ermöglicht wird.According to a preferred embodiment, the drive of the dismantling tools is stored in the pressure bell and the axis of rotation of this drive is pivoted together with the pressure bell, whereby a uniform utilization and thus a high, adapted, constant removal performance is made possible in each pivot position of the pressure bell according to the required supporting pressure.

In besonders vorteilhafter Weise wird das erfindungsgemäße Verfahren mit einer entsprechend sicheren Meßmethodik ergänzt und mit Vorteil so ausgeführt, daß die Druckbelastung der Druckglocke gemessen und daß die Druckglocke in Abhängigkeit von den gemessenen Werten von einer Mehrzahl von gesonderten Verschiebe- oder Schwenkantrieben verstellt wird. Durch die Messung der Druckbelastung der Druckglocke wird eine Mehrzahl von repräsentativen Meßwerten gewonnen, welche es ermöglichen, die Verschiebe- oder Schwenkbewegung dieser Druckglocke entsprechend den gemessenen Druckwerten vorzunehmen.In a particularly advantageous manner, the method according to the invention is supplemented with a correspondingly reliable measuring method and is advantageously carried out in such a way that the pressure load on the pressure bell is measured and that the pressure bell is adjusted as a function of the measured values by a plurality of separate displacement or swivel drives. By measuring the pressure load on the pressure bell, a plurality of representative measured values are obtained, which make it possible to carry out the displacement or pivoting movement of this pressure bell in accordance with the measured pressure values.

Die erfindungsgemäße Vorrichtung zur Durchführung dieses Verfahrens ist ausgehend von der eingangs erwähnten Vorrichtung im wesentlichen dadurch gekennzeichnet, daß die einen Antrieb für das Abbauwerkzeug abdichtende Druckglocke in Längsrichtung der Schildkonstruktionen dichtend verschieblich und gegenüber der Längsrichtung der Schildkonstruktion schwenkbar angeordnet ist, und daß die Druckglocke mit Druck- und/oder Wegaufnehmern sowie Verschiebe- und/oder Schwenkantrieben verbunden ist. Durch die Maßnahme, daß die Druckglocke in Längsrichtung der Schildkonstruktion dichtend verschieblich und gegenüber der Längsrichtung der Schildkonstruktion schwenkbar angeordnet ist, wird die Möglichkeit geschaffen, diese Druckglocke entsprechend den jeweiligen Erfordernissen an die Ortsbrust anzustellen, um auf diese Weise eine regionale Kompensation des Erddruckes entsprechend den geologischen Verhältnissen sicherzustellen. Die Anpressung der Druckglocke erfolgt über jeweils gesonderte, zweckmäßig angeordnete Verschiebe- und/oder Schwenkantriebe, die zur besseren Steuerung der Verschiebe- und/oder Schwenkbewegung mit Druck- und/oder Wegaufnehmern verbunden sind.The device according to the invention for carrying out this method is essentially characterized, starting from the device mentioned at the outset, in that the pressure bell sealing a drive for the removal tool is sealingly displaceable in the longitudinal direction of the shield constructions and is pivotable with respect to the longitudinal direction of the shield construction, and in that the pressure bell is pressurized - And / or displacement transducers and displacement and / or swivel drives is connected. The measure that the pressure bell is arranged sealingly displaceable in the longitudinal direction of the shield construction and pivotable relative to the longitudinal direction of the shield construction, the possibility is created to set this pressure bell according to the respective requirements of the working face, in order in this way a regional compensation of the earth pressure according to the ensure geological conditions. The pressure bell is pressed by separate, appropriately arranged displacement and / or swivel drives which are connected to pressure and / or displacement transducers for better control of the displacement and / or swivel movement.

Eine besonders einfache Kombination von Druck- bzw. Wegaufnehmern mit Verschiebe- und/oder Schwenkantrieben kann bei Verwendung von hydraulischen Zylinder-Kolbenaggregaten erzielt werden, wodurch eine gezielte Verschwenkung der Druckglocke entsprechend den Druckverhältnissen ermöglicht wird.A particularly simple combination of pressure transducers or displacement transducers with displacement and / or swivel drives can be achieved when using hydraulic cylinder-piston units, which enables the pressure bell to be pivoted in a targeted manner according to the pressure conditions.

In besonders einfacher Weise können die Verschiebe- und/oder Schwenkantriebe der Druckglocke von Fluidikzylinder-Kolbenaggregaten gebildet sein und die Druckaufnehmer als an den Arbeitsraum der Fluidikzylinder angeschlossene Druckmesser ausgebildet sein. Derartige Fluidikzylinder-Kolbenaggregate bieten den Vorteil, daß sie neben ihrer Funktion als Antrieb für die Verschiebe- oder Schwenkbewegung der Druckglocke gleichzeitig auch als Meßaufnehmer dienen können, wobei es in solchen Fällen genügt, anstelle aufwendiger Wegaufnehmer einfache Druckmesser mit dem Arbeitsraum der jeweiligen Fluidikzylinder zu verbinden.In a particularly simple manner, the displacement and / or swivel drives of the pressure bell can be formed by fluidic cylinder piston units and the pressure transducers can be designed as pressure gauges connected to the working space of the fluidic cylinders. Fluidic cylinder piston units of this type offer the advantage that, in addition to their function as a drive for the displacement or pivoting movement of the pressure bell, they can also serve as measuring sensors, in which case it is sufficient to connect simple pressure gauges to the working space of the respective fluidic cylinders instead of complex displacement sensors .

Mit Vorteil können die Verschiebe- und/oder Schwenkantriebe und im besonderen die Fluidikzylinder-Kolbenaggregate an einer innerhalb der Schildkonstruktion abgestützten Trägerkonstruktion abgestützt sein. Auf diese Weise wird ein relativ zur Schildkonstruktion ortsfestes Widerlager für die Antriebe geschaffen und es wird die Möglichkeit geschaffen, die Druckglocke nicht nur zur Aufnahme des Erddruckes, sondern auch zur Richtungssteuerung zu benutzen. Die Stütz- und Steuerzylinder für die Druckglocke bzw. für die einzelnen beweglichen Wandteile der Druckglocke können hiebei einzeln oder in Gruppen zur Gewinnung der Druckmeßwerte des Enddruckes und zur aktiven Steuerung eingesetzt werden.The displacement and / or swivel drives, and in particular the fluidic cylinder piston units, can advantageously be supported on a support structure supported within the shield construction. In this way, an abutment which is stationary relative to the shield construction is created for the drives and the possibility is created to use the pressure bell not only for receiving the earth pressure, but also for directional control. The support and control cylinders for the pressure bell or for the individual movable wall parts of the pressure bell can be used individually or in groups for obtaining the pressure measurements of the final pressure and for active control.

Die Verwendung einer derartigen Trägerkonstruktion für die Abstützung von Fluidikzylinder-Kolbenaggregate, welche als Stütz- und Steuerzylinder eingesetzt werden können, bietet darüberhinaus mit Vorteil die Möglichkeit eine Lagerung, insbesondere eine die axiale Verschiebung zulassende Gleitlagerung und eine die Verschwenkung der Achslage zulassende Schwenklagerung des Antriebes der Abbauwerkzeuge zu tragen. Eine derartige Ausbildung ermöglicht die weitgehend uneingeschränkte Beweglichkeit der Abbauwerkzeuge, so daß auch ein Vorschneiden vor der Ortsbrust im Betrieb im Bedarfsfall genutzt werden kann.The use of such a support structure for the support of fluidic cylinder piston assemblies, which can be used as support and control cylinders, also advantageously offers the possibility of a bearing, in particular a slide bearing that allows axial displacement and a pivot bearing of the drive that allows pivoting of the axial position Carry dismantling tools. Such training enables the largely unrestricted mobility of the mining tools, so that pre-cutting in front of the working face can also be used in operation if necessary.

Mit Vorteil ist die Trägerkonstruktion als weitere dichtende Wand in der Schildkonstruktion ausgebildet, so daß ein zusätzlicher Sicherheitsraum ausgebildet wird. Im Falle des Auftretens von Undichtheiten im Bereich der Druckglocke kann dieser zusätzliche Sicherheitsraum durch Einleiten von Druckluft gefüllt werden, so daß eine erhöhte Sicherheit des Betriebspersonals gegeben ist. Die verschiebliche Druckglocke selbst kann zum Schild parallele Ränder aufweisen, wodurch die Randabdichtung wesentlich vereinfacht wird. Um eine Verschwenkung der Druckglocke bei gleichzeitiger Aufrechterhaltung der Dichtung sicherzustellen, kann die Druckglocke in Gleitlagern, insbesondere balligen Gleitlagern, an der Antriebswelle oder dem die Antriebswelle umgebenden Gehäuse abgestützt sein.The support structure is advantageously designed as a further sealing wall in the shield construction, so that an additional security room is formed. In the event of leaks in the area of the pressure bell, this additional safety space can be filled by introducing compressed air, so that the operating personnel are provided with increased safety. The movable pressure bell itself can have edges parallel to the shield, which considerably simplifies the edge sealing. In order to ensure that the pressure bell pivots while maintaining the seal, the pressure bell can be supported in slide bearings, in particular spherical slide bearings, on the drive shaft or on the housing surrounding the drive shaft.

Die Antriebswelle des Schneidrades muß die Druckglocke durchsetzen und kann mit Vorteil hohl ausgebildet sein, wodurch die Möglichkeit geschaffen wird, eine Abfördereinrichtung innerhalb der hohl ausgebildeten Antriebswelle anzuordnen. Alternativ oder zusätzlich kann die Druckglocke eine Durchbrechung für den Anschluß einer Abfördereinrichtung aufweisen, wodurch der sichere und rasche Abtransport des geschnittenen Materials bei gleichzeitiger Aufrechterhaltung des geforderten Druckes möglich ist.The drive shaft of the cutting wheel must pass through the pressure bell and can advantageously be hollow, which creates the possibility of arranging a discharge device within the hollow drive shaft. As an alternative or in addition, the pressure bell can have an opening for the connection of a discharge device, as a result of which the cut material can be transported away safely and quickly while at the same time maintaining the required pressure.

Für Wartungsarbeiten kann es erforderlich sein, den Druckraum zugänglich zu machen, und zu diesem Zweck ist mit Vorteil die Ausbildung so getroffen, daß die Druckglocke und gegebenenfalls zusätzlich die Trägerkonstruktion eine Schleuse aufweist.For maintenance work it may be necessary to make the pressure chamber accessible, and for this purpose the design is advantageously made such that the pressure bell and optionally also the support structure have a lock.

Die Fluidikzylinder-Kolbenaggregate, welche in besonders einfacher Weise als Hydraulikzylinder-Kolbenaggregate ausgebildet sein können, sind über den gesamten Umfang der Druckglocke verteilt angeordnet, wodurch zum einen die Erfassung und Registrierung des Erddruckes über die gesamte Abbaufläche bzw. Ortsbrust möglich ist und zum anderen die unterschiedlichen Erddrücke in Abhängigkeit von Vortriebsmaschinen-Durchmesser in allen Höhenlagen vor der Schildmaschine, insbesondere in der Firste, Ulme und Sohle eindeutig gemessen und erfaßt werden können. Die Anordnung der hydraulischen Zylinder-Kolbenaggregate am Umfang ermöglicht zum anderen die sichere Abstützung gegen die eigentliche Schildkonstruktion, so daß auch große Kräfte sicher aufgenommen bzw. ausgeübt werden können.The fluidic cylinder piston assemblies, which can be designed in a particularly simple manner as hydraulic cylinder piston assemblies, are arranged distributed over the entire circumference of the pressure bell, whereby on the one hand the detection and registration of the earth pressure over the entire mining area or Face is possible and on the other hand the different earth pressures depending on the diameter of the tunneling machine can be clearly measured and recorded in all heights in front of the shield machine, especially in the roof, elm and sole. The arrangement of the hydraulic cylinder-piston units on the circumference also enables secure support against the actual shield construction, so that even large forces can be safely absorbed or exerted.

Auf Grund der genauen Erfassung des Erddruckes über die gesamte Baufläche läßt sich auf in wesentlich exakterer Weise der Austrag des abgebauten Bodenmateriales aus der Abbaukammer einer Regelung unterwerfen. Für den Bodenabtransport sind hiebei in erster Linie Schneckenförderer oder ähnliche Systeme geeignet, wobei zusätzlich Zellenräder, Stauklappen od.dgl. angeordnet werden, um den Abfluß des abgebauten Erdreiches exakt steuern zu können.Due to the precise recording of the earth pressure over the entire construction area, the discharge of the mined soil material from the mining chamber can be subjected to a control in a much more precise manner. Screw conveyors or similar systems are primarily suitable for the removal of soil, with additional cellular wheels, storage flaps or the like. be arranged in order to be able to control the runoff of the mined soil exactly.

Die Steuerung der Stütz- und Steuerzylinder bzw. der Verschiebe- und Schwenkantriebe der Druckglocke kann in einfacher Weise mittels eines frei programmierbaren Schaltwerkes erfolgen, wobei mit Vorzug die Ausbildung so getroffen ist, daß die Signalleitungen der Druckmeßeinrichtungen und/oder Wegaufnehmer mit einem frei programmierbaren Schaltwerk verbunden sind und daß Steuerleitungen des frei programmierbaren Schaltwerkes mit den Antrieben, insbesondere Ventilen der Fluidikantriebe, der verschieblichen und schwenkbaren Druckglocke verbunden sind.The control of the support and control cylinders or the displacement and swivel drives of the pressure bell can be carried out in a simple manner by means of a freely programmable switching mechanism, the design preferably being such that the signal lines of the pressure measuring devices and / or displacement transducers have a freely programmable switching mechanism are connected and that control lines of the freely programmable switching mechanism are connected to the drives, in particular valves of the fluidic drives, of the displaceable and pivotable pressure bell.
