Abstract

The fluid shield for forward tunnel working comprises a shield cover (1), at front end of which is cutting wheel and chamber formed with pressure wall partly filled with support fluid. The chamber is divided by a wall into a front disintegration chamber with the cutting wheel and a rear work chamber, which via a recess aperture formed by the wall in the shield sole area (14) is connected to the disintegration chamber. In the work chamber, the support fluid can be set at a predetermined pressure with the aid of a compressed air cushion and a corresponding control device. The floor material cut away by the cutting wheel, together with support fluid, is fed away via a stone breaker (11) and through a rake (25) by means of a conveyor conduit (12) issuing into the work chamber.

Description

Die vorliegende Erfindung betrifft einen Flüssigkeitsschild für einen Tunnelvortrieb, bestehend aus einem Schildmantel und einem im Bereich des in Vortriebsrichtung gesehen vorderen Endes des Schildmantels angeordneten Schneidrad, wobei im vorderen Bereich des Schildmantels mit Hilfe einer Druckwand eine teilweise mit Stützflüssigkeit gefüllte Kammer gebildet ist, die durch eine Tauchwand in eine das Schneidrad aufweisende vordere Abbaukammer und eine dahinterliegende Arbeitskammer geteilt ist, welche durch eine von der Tauchwand im Schildsohlbereich gebildete Ausnehmungsöffnung mit der Abbaukammer in Verbindung steht und in welcher die Stützflüssigkeit mit Hilfe eines Druckluftpolsters und einer zugeordneten Steuereinrichtung unter einen vorgegebenen Druck setzbar ist, wobei das vom Schneidrad hereingewonnene Bodenmaterial zusammen mit Stützflüssigkeit durch die Ausnehmungsöffnung über einen Steinbrecher und durch einen Rechen über eine im Bereich der Druckwand in der Arbeitskammer mündende Förderleitung abtransportierbar und die Stützflüssigkeit nach Entfernung des Bodenmaterials über eine Rückführleitung in die Abbaukammer zurückführbar ist.The present invention relates to a liquid shield for tunneling, consisting of a shield jacket and one in the area of the front seen in the direction of advance End of the shield shell arranged cutting wheel, being in the front area of the shield jacket with the help of a Pressure wall of a chamber partially filled with support fluid is formed by a baffle in the Cutting chamber with front cutting chamber and a rear one Chamber of Labor is divided by one recess opening formed by the baffle in the shield sole area communicates with the mining chamber and in which the support fluid using a compressed air cushion and an associated control device under a predetermined pressure can be set, the dated Cutting wheel extracted soil material together with Support fluid through the recess opening through a Stone crusher and through a rake over one in the area the delivery line leading to the pressure wall in the working chamber removable and the support fluid after removal of the soil material via a return line to the excavation chamber is traceable.

Bei aus der Praxis bekannten, im Einsatz befindlichen Flüssigkeitsschilden der genannten Art erfolgt die Stützdrucksteuerung regelmäßig derart, dass die Abbaukammer vollständig mit der Stützflüssigkeit gefüllt ist, die zumeist aus einer Bentonitsuspension besteht. Die hinter der Abbaukammer liegende Arbeitskammer ist nur teilweise mit dieser Bentonitsuspension gefüllt. Darüber angeordnet befindet sich das Druckluftpolster. Durch eine im Sohlbereich befindliche Ausnehmungsöffnung der die Abbaukammer von der Arbeitskammer trennenden Tauchwand entsteht so ein Druckregelungsprinzip nach Art der kommunizierenden Röhren. Wird also das Druckluftpolster unter Druck gesetzt, wird damit auch die Flüssigkeit in der Arbeitskammer unter Druck gesetzt. Durch die im Sohlbereich befindliche Ausnehmungsöffnung wird dieser Druck nach dem Prinzip der kommunizierenden Röhren in die Abbaukammer geführt, so dass die Stützflüssigkeit im Bereich der Abbaukammer zur Stützung der Ortsbrust unter Druck gesetzt werden kann. Gleichzeitig dient die Ausnehmungsöffnung auch der Materialförderung des durch das Schneidrad abgebauten Bodens. Der durch das Schneidrad hereingewonnene Boden sinkt in der Stützflüssigkeit in Richtung Schildsohle und wird durch die Ausnehmungsöffnung zu einem Absaugstutzen der Förderleitung geführt. Über diese Förderleitung wird ein definierter Volumenstrom der Stützflüssigkeit abgezogen und einer Separieranlage zugeführt. In dieser Separieranlage wird das Bodenmaterial von der Stützflüssigkeit getrennt. Die Suspension wird anschließend wieder der Abbaukammer zugeführt. Insbesondere wenn nichtbindige oder bindige Böden mit Steinblöcken aufgefahren werden sollen, wird unmittelbar hinter der Ausnehmungsöffnung ein Steinbrecher, üblicherweise ein Zangenbrecher oder ein Backenbrecher, benutzt, der die Steine und Findlinge auf ein förderfähiges Maß herunterbricht. Dieses förderfähige Maß wird definiert durch den vor dem Ansaugstutzen der Förderleitung befindlichen Rechen mit definierter Durchgangsöffnungsweite. In liquid shields known from practice and in use the support pressure control takes place of the type mentioned regularly such that the mining chamber is complete is filled with the support liquid, which mostly consists of a bentonite suspension. The one behind the mining chamber lying working chamber is only partially with this Bentonite suspension filled. Located above it the compressed air cushion. By a located in the sole area Recess opening of the removal chamber from the Working chamber separating baffle is thus a pressure control principle according to the type of communicating tubes. Becomes So the compressed air cushion is pressurized also the liquid in the working chamber under pressure set. Through the recess opening in the bottom area this pressure is based on the principle of communicating Tubes into the mining chamber so that the Support fluid in the area of the extraction chamber for support the face can be pressurized. simultaneously the opening also serves to promote the material soil removed by the cutting wheel. The one through that Cutting wheel soil sinks in the supporting fluid towards the sole of the shield and is through the recess opening led to a suction port of the delivery line. A defined volume flow is generated via this delivery line the supporting fluid is withdrawn and a separating system fed. In this separation system, Soil material separated from the support liquid. The suspension is then returned to the mining chamber. Especially when using non-cohesive or cohesive soils Stone blocks are to be excavated immediately a stone crusher behind the opening, usually a crusher or a jaw crusher, used, that breaks the stones and boulders down to an eligible level. This eligible measure is defined by the one in front of the intake pipe of the delivery line Rake with a defined opening width.

Bei diesen bekannten Flüssigkeitsschilden kommt es insbesondere bei der Durchfahrung von bindigen Bodenformationen zu Bodenablagerungen im Sohlbereich sowohl der Arbeitskammer als auch der Abbaukammer. Diese Bodenablagerungen führen zu Beschädigungen und Verschleiß der Schildvortriebsmaschine im Bereich dieser Bodenablagerungen. Weiterhin müssen diese Bodenablagerungen bei erforderlichen Reparaturen im Sohlbereich des Schildes zeitintensiv und gegebenenfalls unter Druckluftbedingungen geräumt werden.In these known liquid shields, this is particularly the case when driving through cohesive ground formations for soil deposits in the sole area of both the working chamber as well as the mining chamber. These soil deposits result damage and wear to the shield tunneling machine in the area of these soil deposits. Farther need these floor deposits for any necessary repairs time-consuming and possibly in the sole area of the shield be cleared under compressed air conditions.

Aufgabe der vorliegenden Erfindung ist es nunmehr, diese Materialaufstauungen im Sohlbereich des Schildes in der Arbeitskammer sowie in der Abbaukammer zu verhindern.The object of the present invention is now this Material build-up in the sole area of the shield in the Prevent working chamber and in the mining chamber.

Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, dass der um die Ausnehmungsöffnung herum liegende Schildsohlbereich der Arbeitskammer durch eine zwischen der Tauchwand und der Druckwand verlaufende Trennwandanordnung gegenüber der restlichen Arbeitskammer gekapselt ist und die restliche Arbeitskammer durch mindestens zwei Stützflüssigkeitsleitungen mit der Abbaukammer verbunden ist.The solution to this problem according to the invention consists in that the shield sole area lying around the recess opening the Chamber of Labor through a between the Baffle and the partition wall arrangement extending is encapsulated in relation to the rest of the working chamber and the remaining working chamber through at least two supporting fluid lines is connected to the mining chamber.

Beim erfindungsgemäßen Flüssigkeitsschild ist der Schildsohlbereich der Arbeitskammer abgekapselt, um eine zielgerichtete Zwangsförderung des Bodenmaterials zum Saugstutzen der Förderleitung hin zu erreichen. Steinbrecher, Rechen und Saugstutzen der Förderleitung liegen demzufolge im abgekapselten Bereich, in dem sich nunmehr keine Bodenablagerungen mehr bilden können. Durch die Abkapselung ist aber die Kommunikation zwischen Arbeitskammer und Abbaukammer zur Steuerung des Stützdruckes unterbunden. Diese Kommunikation wird nun wieder hergestellt durch die beiden zusätzlichen Stützflüssigkeitsleitungen. Im Ergebnis ist so die Funktion der Bodenmaterialförderung von der Funktion der Stützdrucksteuerung entkoppelt.In the liquid shield according to the invention, the shield sole area is the work chamber encapsulated to a targeted Forced conveyance of the floor material to the suction nozzle to reach the delivery line. Stone crusher, rake and suction port of the delivery line are therefore encapsulated Area in which there are now no soil deposits can make more. Because of the encapsulation but the communication between the working chamber and the mining chamber to control the support pressure prevented. This Communication is now restored by the two additional support fluid lines. The result is so the function of soil material promotion from the function decoupled from the support pressure control.

Für die weitere Ausgestaltung bestehen im Rahmen der Erfindung mehrere Möglichkeiten. So ist nach einer bevorzugten Ausführungsform die Trennwandanordnung von zwei etwa radial von der Schildsohle bis zu einem zentralen Hauptlagergehäuse des Schneidrades verlaufenden Trennwänden gebildet. Darüber hinaus empfiehlt es sich, die Anordnung so zu treffen, dass der gekapselte Schildsohlbereich der Arbeitskammer durch begehbare Klappen in der Trennwandanordnung und/oder Druckwand zugänglich ist, um beispielsweise Reparaturen am Steinbrecher zu ermöglichen. Ferner ist es zur Vermeidung von Bodenmaterialablagerungen in der restlichen Arbeitskammer empfehlenswert, die Stützflüssigkeitsleitungen im Bereich des Tiefsten der restlichen Arbeitskammer und oberhalb der halben Schildhöhe in der Tauchwand münden zu lassen und/oder in wenigstens einer der beiden Stützflüssigkeitsleitungen einen Zwangsförderer insbesondere in Form einer Förderschnecke anzuordnen. Selbstverständlich kann die Ausnehmungsöffnung wie bekannt durch einen Tauchwandschieber verschließbar sein, um z.B. eine 1/3-Absenkung der Stützflüssigkeit in der Abbaukammer durchführen zu können. Die selbe Möglichkeit eröffnet sich aber auch, wenn alternativ oder in Kombination dazu in der Förderleitung ein Absperrschieber vorgesehen ist. Schließlich und endlich empfiehlt es sich, die Trennwandanordnung mit einem Rohrdurchbruch zu versehen, der den gekapselten Schildsohlbereich der Arbeitskammer durchsetzt und die unteren Bereiche der restlichen Arbeitskammer miteinander verbindet.For the further embodiment there are within the scope of the invention more options. So is after a preferred one Embodiment the partition arrangement of about two radially from the shield sole to a central main bearing housing of the cutting wheel extending partition walls. In addition, it is advisable to arrange it this way to meet that encapsulated shield sole area of the work chamber through accessible flaps in the partition arrangement and / or pressure wall is accessible, for example To enable repairs to the stone crusher. Further it is to avoid soil material deposits in the the rest of the working chamber, the supporting fluid lines are recommended in the range of the lowest of the rest Working chamber and above half the plate height in the Let the baffle open and / or in at least one of the two support fluid lines in particular a positive conveyor to be arranged in the form of a screw conveyor. Of course can the opening as known through a sliding gate can be closed, e.g. a 1/3 lowering of the support fluid in the extraction chamber to be able to perform. The same possibility opens up but also if, alternatively or in combination, in the Delivery line a gate valve is provided. Finally and finally it is advisable to arrange the partition to be provided with a pipe breakthrough that the encapsulated The sole of the working chamber is interspersed and the lower areas of the rest of the working chamber combines.
