Die Erfindung betrifft eine Vorrichtung zur Herstellung eines mehrere Tunnelabschnitte aufweisenden Tunnels, insbesondere Absenktunnels, mit einer Betonierstation zum taktweisen Betonieren von Tunnelabschnitten, wobei die Betonierstation eine Schalungsanordnung mit einer Bodenschalung aufweist, wobei eine Schubeinrichtung zum Verschieben der Tunnelabschnitte in Längsrichtung aus der Betonierstation in eine Parkstation vorgesehen ist, wobei eine Trageinrichtung, bevorzugt ein Gitterträger, zur Abstützung einer Innenschalung der Schalungsanordnung vorgesehen ist.The invention relates to a device for producing a tunnel having several tunnel sections, in particular immersed tunnel, with a concreting station for cyclic concreting of tunnel sections, wherein the concreting station has a formwork arrangement with a bottom formwork, wherein a pushing device for moving the tunnel sections in the longitudinal direction of the concreting in a parking station is provided, wherein a support means, preferably a lattice girder, is provided for supporting an inner formwork of the formwork arrangement.
Weiters betrifft die Erfindung ein Verfahren zur Herstellung eines mehrere Tunnelabschnitte aufweisenden Tunnels, insbesondere Absenktunnels, wobei in einer Betonierstation eine Schalungsanordnung mit einer Bodenschalung vorgesehen wird, mit welcher taktweise die Tunnelabschnitte betoniert werden, welche im ausbetonierten Zustand in Längsrichtung von der Betonierstation in eine Parkstation geschoben werden, wobei eine Trageinrichtung, bevorzugt ein Gitterträger, zur Abstützung einer Innenschalung der Schalungsanordnung vorgesehen wird.Furthermore, the invention relates to a method for producing a tunnel sections having several tunnel sections, in particular immersed tunnel, wherein in a concreting a formwork arrangement is provided with a bottom formwork with which cyclically the tunnel sections are concreted, which pushed in the concreted state in the longitudinal direction of the concreting in a parking station be, with a support means, preferably a lattice girder, is provided for supporting an inner formwork of the formwork arrangement.
Ein Verfahren zur Herstellung eines Unterwassertunnels ist beispielsweise aus der
Zur Abstützung einer Innenschalung der Schalungsanordnung ist üblicherweise eine Trageinrichtung vorgesehen, welche beim Stand der Technik einen Gitterträger sowie einen Käfig zur Auflagerung und Führung des Gitterträgers aufweist. Bisher wurden der Gitterträger mit dem Käfig und die Innenschalung zusammen mit dem fertigen Tunnelabschnitt aus der Betonierstation geschoben. Nach dem Verschieben des Tunnelabschnitts in die Parkstation wurden der Gitterträger und die Schalung in die Betonierstation zurückgeführt, bevor eine Reinigung der Schalung durchgeführt wurde. Nachteiligerweise konnte daher mit der Reinigung der Schalung erst begonnen werden, nachdem der Vorschub des Tunnelabschnitts abgeschlossen war und die Schalung zurück in die Betonierstation geschoben wurde. Dieser Ablauf war daher nachteiligerweise zeitaufwendig. Für den Verschub des Gitterträgers bzw. der Schalung waren darüber hinaus Rollenführungen und eine damit zusammenhängende hydraulische Verschubeinrichtung erforderlich, um den Gitterträger bzw. den Käfig zusammen mit der Schalung verschieben zu können. Demnach war nachteiligerweise ein beträchtlicher konstruktiver Aufwand zur Längsführung des Gitterträgers bzw. des Käfigs erforderlich.To support an inner formwork of the formwork arrangement, a carrying device is usually provided, which in the prior art has a lattice girder and a cage for bearing and guiding the lattice girder. So far, the lattice girder with the cage and the inner formwork were pushed out of the concreting station together with the finished tunnel section. After moving the tunnel section into the parking station, the lattice girder and the formwork were returned to the concreting station before a cleaning of the formwork was carried out. Disadvantageously, therefore, could be started with the cleaning of the formwork only after the advance of the tunnel section was completed and the formwork was pushed back into the concreting. This process was therefore disadvantageously time consuming. For the shifting of the lattice girder or the shuttering were also roller guides and a related Hydraulic Verschubeinrichtung required to move the lattice girder or the cage together with the formwork can. Accordingly, a considerable design effort for longitudinal guidance of the lattice girder or the cage was disadvantageously required.
Ähnliche Vorrichtungen, bei welchen ein verschieblicher Träger zum Tragen der Innenschalung vorgesehen ist, sind beispielsweise auch aus der
Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, die Nachteile des Standes der Technik zu eliminieren bzw. zu lindern. Die Erfindung setzt sich daher insbesondere zum Ziel, den Ablauf bei der Herstellung der Tunnelsegmente zu vereinfachen und zu beschleunigen.In contrast, the object of the present invention is to eliminate or alleviate the disadvantages of the prior art. The invention is therefore particularly aimed at simplifying and accelerating the sequence in the production of the tunnel segments.
Diese Aufgabe wird durch eine Vorrichtung gemäß Anspruch 1 und ein Verfahren gemäß Anspruch 8 gelöst. Bevorzugte Ausführungen der Erfindung sind in den hiervon abhängigen Ansprüchen angegeben.This object is achieved by a device according to
Erfindungsgemäß sind die Trageinrichtung und die Innenschalung im Wesentlichen stationär angeordnet.According to the invention, the carrying device and the inner formwork are arranged substantially stationary.
Beim Verschieben des fertig betonierten Tunnelabschnitts aus der Betonierstation ist die Trageinrichtung sowie die Innenschalung stationär, d.h. in Längsrichtung unverschieblich, in der Betonierstation angeordnet. Demnach ist der Tunnelabschnitt relativ zu der stationären Trageinrichtung bzw. zu der stationären Schalungsanordnung verschieblich gelagert. Da die Trageinrichtung samt Innenschalung beim Verschubvorgang in der Betonierstation verbleibt und daher anders als beim Stand der Technik nicht mehr bewegt werden muss, kann einerseits auf die Anordnung eines Käfigs und andererseits auf die Verschubeinrichtung für die Trageinrichtung verzichtet werden, wodurch erhebliche Material- bzw. Kosteneinsparungen erzielt werden können. Vorteilhafterweise kann zudem mit der Reinigung der Innenschalung begonnen werden, noch während der Tunnelabschnitt aus der Betonierstation geschoben wird. Die Trageinrichtung ist bevorzugt als Gitterträger ausgeführt; es kann jedoch alternativ auch ein Vollwandträger vorgesehen sein.When moving the finished concreted tunnel section from the concreting the support device and the inner formwork is stationary, ie non-displaceable in the longitudinal direction, arranged in the concreting station. Accordingly, the tunnel section is displaceably mounted relative to the stationary support device or to the stationary formwork arrangement. Since the carrying device together with inner formwork remains during Verschubvorgang in the concreting and therefore unlike the prior art does not need to be moved, on the one hand to dispense with the arrangement of a cage and on the other hand on the Verschubeinrichtung for the support means, resulting in significant material or cost savings can be achieved. Advantageously, in addition, the cleaning of the inner formwork can be started even while the tunnel section is being pushed out of the concreting station. The carrying device is preferably as a lattice girder performed; However, it can alternatively be provided a solid wall support.
Die Schalungsanordnung kann, wie üblich, eine zwischen einer geschlossenen Betonierposition und einer geöffneten Position überführbare Stirnschalung aufweisen. Um bei einer stationären Ausführung der Trageinrichtung und der Innenschalung auf besonders einfache Weise eine Bewehrung in der Schalungsanordnung vorsehen zu können, ist bevorzugt vorgesehen, dass die Trageinrichtung für die Innenschalung auf der Seite der Stirnschalung ein zwischen einer an einem Boden der Betonierstation abgestützten Stützstellung und einer vom Boden abgehobenen Stellung überführbares Stützelement aufweist. In der vom Boden abgehobenen Stellung des Stützelements der Trageinrichtung, in der geöffneten Position der Stirnschalung ist eine Einführöffnung zum Einführen einer Bewehrung in die Schalungsanordnung ausgebildet. Um die Bewehrung in der Schalungsanordnung vorzusehen, wird daher einerseits die Stirnschalung geöffnet. Andererseits wird das Stützelement vom Boden abgehoben. Dadurch wird an der Stirnseite der Schalungsanordnung eine Einführöffnung ausgebildet, durch welche die Bewehrung zwischen die Schalungselemente der Schalungsanordnung geschoben werden kann. Die Schalungsanordnung einschließlich der Innenschalung und die Trageinrichtung sind während dieses Vorgangs in Längsrichtung stationär in der Betonierstation angeordnet. Bei einer bevorzugten Ausführung ist zum Zeitpunkt des Bewehrungseinschubes eine Innenschalung in einer Ausschalstellung angeordnet, wobei der Gitterträger und eine Deckenschalung abgesenkt und eine Wandschalung sowie Bodenklappen eingezogen sind. Zum Betonieren des Tunnelabschnitts wird einerseits die Stirnschalung in die geschlossene Betonierstellung gebracht und andererseits das Stützelement auf dem Boden abgestützt. Als Stützelement ist bevorzugt ein in der Höhe verstellbares Steherelement vorgesehen.The formwork arrangement can, as usual, have an end formwork that can be transferred between a closed concreting position and an open position. In order to provide a reinforcement in the formwork arrangement in a stationary embodiment of the support means and the inner formwork in a particularly simple manner, it is preferably provided that the support means for the inner formwork on the side of the front formwork between a supported at a bottom of the concreting support position and a From the ground off position has convertible support member. In the raised position of the support element of the support device, in the open position of the front formwork, an insertion opening for introducing a reinforcement in the formwork arrangement is formed. In order to provide the reinforcement in the formwork arrangement, therefore, on the one hand, the front formwork is opened. On the other hand, the support element is lifted off the ground. As a result, an insertion opening is formed on the front side of the formwork arrangement, through which the reinforcement can be pushed between the formwork elements of the formwork arrangement. The formwork arrangement including the inner formwork and the support means are arranged in the longitudinal direction stationary in the concreting station during this process. In a preferred embodiment, an inner formwork is arranged in a Ausschalstellung at the time of reinforcement insert, wherein the lattice girder and a slab formwork lowered and a wall formwork and bottom flaps are retracted. For concreting the tunnel section, on the one hand the front formwork is brought into the closed concreting position and, on the other hand, the supporting element is supported on the floor. As a support element, a height-adjustable upright element is preferably provided.
Die Trageinrichtung weist üblicherweise einen in der Betonierstation verlaufenden Längsabschnitt und einen in der Parkstation verlaufenden Längsabschnitt auf. Um eine stationäre Anordnung der Trageinrichtung beim Verschieben des fertigen Tunnelabschnitts zwischen der Betonierstation und der Parkstation zu ermöglichen, ist es günstig, wenn der in der Betonierstation verlaufende Längsabschnitt in der die Einführöffnung für die Bewehrung ausbildenden Stellung der Trageinrichtung und der Stirnschalung frei auskragend angeordnet ist, wobei der in der Parkstation verlaufende Längsabschnitt der Trageinrichtung mittels zumindest zweier Abstützelemente an dem zuvor betonierten Tunnelabschnitt abgestützt ist.The carrying device usually has a longitudinal section running in the concreting station and a longitudinal section running in the parking station. In order to enable a stationary arrangement of the support device when moving the finished tunnel section between the concreting station and the parking station, it is advantageous if the running in the concreting station Longitudinal portion in which the insertion opening for the reinforcement forming position of the support means and the front formwork is cantilevered, wherein extending in the parking station longitudinal portion of the support means is supported by at least two support members on the previously concreted tunnel section.
In der die Einführöffnung für die Bewehrung ausbildenden Stellung ist vorzugsweise je ein Abstützelement zur Abstützung an einem Deckenbereich des zuvor betonierten Tunnelabschnitts und ein Abstützelement zur Abstützung an einem Bodenbereich des zuvor betonierten Tunnelabschnitts vorgesehen. Zum Einführen der Bewehrung in die Schalungsanordnung wird, wie zuvor beschrieben, einerseits die Stirnschalung in die geöffnete Position gebracht und andererseits das Stützelement der Trageinrichtung im Bereich der Stirnschalung vom Boden angehoben. Dadurch wird die Trageinrichtung für die Innenschalung entlang der Betonierstation in einer frei auskragenden Stellung, d.h. ohne Abstützung an der Umgebung, angeordnet. Als Trageinrichtung ist bevorzugt ein in dieser Stellung selbsttragender Gitterträger vorgesehen. Zu diesem Zweck weist der in der Parkstation verlaufende Abschnitt der Trageinrichtung zumindest zwei Abstützelemente auf, mit welchen die Trageinrichtung am zuvor betonierten Tunnelabschnitt abstützbar ist. Gemäß einer besonders bevorzugten Ausführung ist die Trageinrichtung in der frei auskragenden Stellung zum Einführen der Bewehrung einerseits an einem von der Betonierstation abgewandten Endbereich der Trageinrichtung mit einem oberseitigen Abstützelement am Deckenbereich des zuvor betonierten, in der Parkstation angeordneten Tunnelabschnitts und andererseits mit einem unterseitigen Abstützelement am Bodenbereich des zuvor betonierten Tunnelabschnitts abgestützt. Das unterseitige Abstützelement wird in dieser Stellung bevorzugt benachbart der Betonierstation zwischen der Trageinrichtung und dem zuvor betonierten Tunnelabschnitt angeordnet.In the position forming the insertion opening for the reinforcement, a support element is preferably provided for support on a ceiling area of the previously concreted tunnel section and a support element for support on a floor area of the previously concreted tunnel section. For introducing the reinforcement into the formwork arrangement, as described above, on the one hand, the front formwork is brought into the open position and on the other hand the support element of the support device in the region of the front formwork raised from the ground. Thereby, the support means for the inner formwork along the concreting station in a cantilevered position, i. without support to the environment, arranged. As a support means in this position a self-supporting lattice girder is preferably provided. For this purpose, the section of the carrying device running in the parking station has at least two supporting elements with which the carrying device can be supported on the previously concreted tunnel section. According to a particularly preferred embodiment, the carrying device is in the cantilevered position for introducing the reinforcement on the one hand at an end facing away from the concreting end of the support device with an upper side support on the ceiling area of the previously concreted, arranged in the park station tunnel section and on the other hand with a lower-side support element on the bottom area supported the previously concreted tunnel section. The lower-side support element is preferably arranged in this position adjacent to the concreting station between the support device and the previously concreted tunnel section.
Gemäß einer bevorzugten Ausführungsvariante ist zumindest ein Abstützelement ein in Längsrichtung relativ zur Trageinrichtung verschiebliches Auflagerelement, insbesondere ein Rollenbock. Alternativ oder zusätzlich kann als Abstützelement ein in Längsrichtung unverschieblich mit der Trageinrichtung verbundenes, in der Höhe verstellbares Steherelement und/oder ein am Deckenbereich des zuvor betonierten Tunnelabschnitts abstützbares lineares Antriebselement vorgesehen sein.According to a preferred embodiment variant, at least one support element is a support element displaceable in the longitudinal direction relative to the support device, in particular a roller block. Alternatively or additionally, as a supporting element in the longitudinal direction immovably connected to the support means, in the height-adjustable upright element and / or a linear drive element which can be supported on the ceiling area of the previously concreted tunnel section can be provided.
Die Verwendung zumindest eines Rollenbocks als Abstützelement hat den Vorteil, dass der Rollenbock in Längsrichtung versetzt werden kann, um während des Herstellungsprozesses verschiedene Funktionen zu erfüllen.The use of at least one roller block as a supporting element has the advantage that the roller block can be displaced in the longitudinal direction in order to fulfill different functions during the production process.
Demnach ist der Rollenbock gemäß einer ersten bevorzugten Ausführung in einer ersten Stellung zwischen dem in der Betonierstation befindlichen Tunnelabschnitt im ausbetonierten Zustand und der Trageinrichtung anordenbar, um das Verschieben dieses Tunnelabschnitts von der Betonierstation in die Parkstation zu unterstützen. Bevorzugt ist der Rollenbock in der ersten Stellung benachbart der Stirnschalung angeordnet. Durch das Verschieben des Tunnelabschnitts in die Parkstation wird der Rollenbock in einer zweiten Stellung, vorzugsweise im Wesentlichen in einem mittleren Längsabschnitt der Trageinrichtung, angeordnet, um eine Abstützung der Trageinrichtung beim Einführen der Bewehrung im angehobenen Zustand des Stützelements zu bewirken. Darüber hinaus kann bei dieser Ausführung ein weiteres versetzbares Auflagerelement, insbesondere ein weiterer Rollenbock, vorgesehen sein, mit welchem die Trageinrichtung beim Verschieben des Tunnelabschnitts im ausbetonierten Zustand unterstützt wird. Um die Trageinrichtung, insbesondere an dem von der Betonierstation abgewandten Ende, an der Decke des zuvor betonierten Tunnelabschnitts abzustützen, wird bevorzugt ein lineares Antriebselement, insbesondere ein hydraulischer Zylinder-Kolben-Antrieb oder ein mechanisches Spindelelement, verwendet.Thus, according to a first preferred embodiment, the roller block is locatable in a first position between the tunnel section in the concreting station in the concreted state and the supporting device in order to assist in moving this tunnel section from the concreting station to the parking station. Preferably, the roller block is arranged in the first position adjacent to the front formwork. By moving the tunnel section into the parking station, the roller block is arranged in a second position, preferably substantially in a central longitudinal section of the carrying device, in order to bring about a support of the carrying device when inserting the reinforcement in the raised state of the support element. In addition, in this embodiment, a further displaceable support element, in particular a further roller block, be provided, with which the support device is supported when moving the tunnel section in the concreted state. In order to support the carrying device, in particular at the end facing away from the concreting station, on the ceiling of the previously concreted tunnel section, a linear drive element, in particular a hydraulic cylinder-piston drive or a mechanical spindle element, is preferably used.
Wie oben beschrieben, weist die Trageinrichtung gemäß einer weiteren bevorzugten Ausführung ein zwischen einer angehobenen und einer abgesenkten Stellung verschiebliches Steherelement auf, welches in Längsrichtung unverschieblich an der Trageinrichtung vorgesehen ist. Bei dieser Ausführung ist das Steherelement bevorzugt in einem mittleren Bereich der Trageinrichtung, bezogen auf deren Längsrichtung, zwischen dem einen Ende der Trageinrichtung auf der Seite der Betonierstation und dem anderen Ende der Trageinrichtung auf der Seite der Parkstation angeordnet. Zudem ist es bei dieser Ausführung bevorzugt, wenn die Trageinrichtung, insbesondere an dem von der Betonierstation abgewandten Ende, ein lineares Antriebselement, insbesondere ein hydraulischer Zylinder-Kolben-Antrieb oder ein mechanisches Spindelelement, aufweist. Bei dieser Ausführung wird bevorzugt nur ein einzelner Rollenbock verwendet, welcher im ausbetonierten Zustand des Tunnelabschnitts, vor dem Verschubvorgang in eine Position benachbart des Steherelements gesetzt wird, so dass der Rollenbock nach dem Verschieben des Tunnelabschnitts in einer Position an dem von der Betonierstation abgewandten Ende der Trageinrichtung angeordnet wird.As described above, according to a further preferred embodiment, the carrying device has a post element which is displaceable between a raised and a lowered position and which is provided on the carrying device in the longitudinal direction so as to be immovable. In this embodiment, the upright element is preferably arranged in a central region of the carrying device, with respect to its longitudinal direction, between the one end of the carrying device on the side of the concreting station and the other end of the carrying device on the side of the parking station. In addition, in this embodiment, it is preferred if the carrying device, in particular at the end remote from the concreting station, has a linear drive element, in particular a hydraulic cylinder-piston drive or a mechanical spindle element. In this embodiment, preferably only a single roller block is used, which is set in the concreted state of the tunnel section, before the Verschubvorgang in a position adjacent the upright element, so that the roller block after moving the tunnel section in a position at the end remote from the concreting end of Carrying device is arranged.
Gemäß einer bevorzugten Ausführung weist die Schubeinrichtung mehrere in Querrichtung voneinander beabstandete und in Längsrichtung verschieblich gelagerte Gleitelemente zur Auflagerung des Tunnelabschnitts in der Betonierstation auf, wobei die Bodenschalung zumindest ein zwischen einer angehobenen Betonierstellung und einer abgesenkten Ausschalstellung höhenverstellbares Bodenschalungselement aufweist, so dass der Tunnelabschnitt im ausbetonierten Zustand in der abgesenkten Ausschalstellung der Bodenschalungselemente gemeinsam mit den Gleitelementen aus der Betonierstation in die Parkstation verschieblich ist.According to a preferred embodiment, the pusher has a plurality of transversely spaced apart and slidably mounted in the longitudinal direction sliding elements for Auflagerung the tunnel section in the concreting, wherein the bottom formwork has at least one height adjustable between a raised concreting and a lowered Ausschalstellung bottom formwork element, so that the tunnel section in the concreted State in the lowered Ausschalstellung the bottom formwork elements is displaceable together with the sliding elements from the concreting in the parking station.
Bei dieser Ausführungsform wird daher im Wesentlichen das gesamte Gewicht des ausgehärteten Tunnelabschnitts in der Betonierstation von den Gleitelementen getragen. Die Gleitelemente sind über Gleit- oder Rolllager auf entsprechenden Verschubbahnen verschieblich geführt. Wesentlich ist hierbei, dass die Gleitelemente direkt, d.h. ohne Linearantriebe wie Hubpressen, auf den Verschubbahnen gelagert sind. Demnach wird der Tunnelabschnitt beim Verschubvorgang zwischen der Betonierstation und der Parkstation im Wesentlichen höhenunveränderlich auf den Gleitelementen gelagert, welche bevorzugt im Wesentlichen starr ausgeführt sind. Zum Verschieben des fertigen Tunnelabschnitts in die Parkstation werden die Bodenschalungselemente in vertikaler Richtung nach unten verschoben bis die Bodenschalungselemente in der abgesenkten Ausschalstellung vorliegen. Daraufhin kann der fertige Tunnelabschnitt mit Hilfe eines geeigneten Linearantriebs zusammen mit den darunterliegenden Gleitelementen in horizontaler Ebene, in Längsrichtung aus der Betonierstation geschoben werden. Vorteilhafterweise ist ein Umlagern des fertigen Tunnelabschnitts nicht mehr erforderlich, da der Tunnelabschnitt sowohl in der Betonierstellung der Bodenschalung als auch in der Ausschalstellung der Bodenschalung durch die Gleitelemente getragen wird. Weiters ist von Vorteil, dass die beim Stand der Technik notwendigen Linearantriebe wie Hubpressen zum Umlagern des fertigen Tunnelabschnittes entfallen können. Darüber hinaus kann der Linearantrieb zum Verschieben des Tunnelabschnitts in horizontaler Ebene mittels der Gleitelemente besonders einfach ausgeführt werden. Schließlich ist es vorteilhaft, dass ein Abklappen der Bodenschalungselemente im Bereich der Verschubbahnen zum Zugriff auf die Hubpressen nicht mehr erforderlich ist. Demnach sind die Bodenschalungselemente in Höhenrichtung zwischen der angehobenen Betonierstellung und angehobenen Ausschalstellung verschieblich.In this embodiment, therefore, substantially the entire weight of the hardened tunnel section in the concreting station is carried by the sliding elements. The sliding elements are guided via sliding or rolling bearings on corresponding Verschubbahnen slidably. It is essential here that the sliding elements are mounted directly, ie without linear drives such as lifting presses, on the Verschubbahnen. Accordingly, the tunnel section during the Verschubvorgang between the concreting station and the parking station is mounted substantially höhenunveränderlich on the sliding elements, which are preferably carried out substantially rigid. To move the finished tunnel section in the parking station, the bottom formwork elements are moved vertically downwards until the bottom formwork elements are present in the lowered Ausschalstellung. Then, the finished tunnel section with the aid of a suitable linear drive together with the underlying sliding elements in the horizontal plane, pushed in the longitudinal direction of the concreting become. Advantageously, a repositioning of the finished tunnel section is no longer necessary, since the tunnel section is supported both in the concreting position of the bottom formwork and in the Ausschalstellung the bottom formwork by the sliding elements. Furthermore, it is advantageous that the necessary in the prior art linear actuators such as lifting presses for repositioning the finished tunnel section can be omitted. In addition, the linear drive for moving the tunnel section in a horizontal plane by means of the sliding elements can be carried out particularly easily. Finally, it is advantageous that a folding down of the bottom formwork elements in the area of the displacement paths for access to the lifting presses is no longer necessary. Accordingly, the bottom formwork elements are displaceable in the height direction between the raised concreting position and raised Ausschalstellung.
Um den Tunnelabschnitt im ausbetonierten Zustand mit konstruktiv einfachen Mitteln und ohne vorheriges Umlagern des Tunnelabschnitts in die Parkstation verschieben zu können, ist es vorteilhaft, wenn als Gleitelemente in Längsrichtung der Betonierstation erstreckte Trägerelemente vorgesehen sind, welche auf der Oberseite Auflageflächen zur Auflage des Tunnelabschnitts und auf der Unterseite Lagerflächen zur Verschiebung auf in Längsrichtung der Betonierstation erstreckten Verschubbahnen aufweisen. Demnach erstrecken sich zwischen der Betonierstation und der Parkstation mehrere Verschubbahnen, auf welchen die Gleitelemente verschieblich gelagert sind. Die Gleitelemente weisen bevorzugt im Wesentlichen dieselbe Längserstreckung wie der Tunnelabschnitt auf. Zum taktweisen Herstellen der Tunnelabschnitte sind bevorzugt mehrere in Längsrichtung der Betonier- bzw. Parkstation aufeinanderfolgende Gleitelemente vorgesehen, so dass der gerade betonierte Tunnelabschnitt gemeinsam mit zumindest einem zuvor betonierten Tunnelabschnitt verschieblich ist. Bevorzugt sind die Lagerflächen zwischen den Gleitelementen und den Verschubbahnen als Gleitlager ausgebildet, wobei alternativ auch Rolllager vorgesehen sein können. Dadurch kann der fertig betonierte Tunnelabschnitt auf den Gleitelementen aus der Betonierstation geschoben werden. Die Gleitelemente sind beim Verschieben des Tunnelabschnitts zwischen der Betonier- und der Parkstation im Wesentlichen höhenunveränderlich angeordnet. Vorteilhafterweise können die beim Stand der Technik üblichen Hubpressen in Form von Hydraulikzylindern zum Umlagern der Tunnelabschnitte entfallen. Nach dem Verschieben des Tunnelabschnitts können in der Betonierstation andere Gleitelemente angeordnet werden, wobei es selbstverständlich auch möglich ist, zuvor verwendeten Gleitelemente rückzugewinnen.In order to move the tunnel section in the concreted state with structurally simple means and without repositioning the tunnel section in the parking station, it is advantageous if extending as sliding elements in the longitudinal direction of the concreting support elements are provided, which on the top bearing surfaces for supporting the tunnel section and on The underside bearing surfaces to move on in the longitudinal direction of the concreting extended Verschubbahnen. Accordingly, extending between the concreting station and the parking station several Verschubbahnen on which the sliding elements are slidably mounted. The sliding elements preferably have substantially the same longitudinal extension as the tunnel section. For cyclically producing the tunnel sections, a plurality of sliding elements following each other in the longitudinal direction of the concreting or parking station are preferably provided, so that the tunnel section just concreted is displaceable together with at least one previously concreted tunnel section. Preferably, the bearing surfaces between the sliding elements and the Verschubbahnen are designed as sliding bearings, wherein alternatively roller bearings can be provided. As a result, the finished concreted tunnel section can be pushed out of the concreting station on the sliding elements. The sliding elements are arranged substantially höhenunveränderlich when moving the tunnel section between the concreting and the parking station. advantageously, The usual in the prior art lifting presses in the form of hydraulic cylinders can be omitted for relocating the tunnel sections. After moving the tunnel section other sliding elements can be arranged in the concreting station, whereby it is of course also possible to recover previously used sliding elements.
Um Veränderungen im Untergrund der Fertigungseinrichtung im Bereich der Verschubbahnen ausgleichen zu können, ist bevorzugt vorgesehen, dass Verstellelemente zur Höhenjustierung der Lagerflächen der Gleitelemente vorgesehen sind. Demnach können die Lagerflächen in der Höhe eingestellt werden, um einen im Wesentlichen ebenen Verlauf der Gleitlager zwischen den Gleitelementen und den Verschubbahnen sicherzustellen. Bei einem Verschubvorgang zwischen der Betonierstation und der Parkstation sind die Gleitelemente jedoch im Wesentlichen in derselben Höhenposition auf den Verschubbahnen verschieblich. Demnach sind insbesondere keine Hubpressen zum Umlagern des Tunnelabschnitts vor dem Verschieben aus der Betonierstation erforderlich. Ein Umlagern der Tunnelelemente auf Absenkkeile nach Erreichen der Endposition zum Ausbau von Hubpressen ist vorteilhafterweise ebenfalls nicht notwendig.In order to be able to compensate for changes in the subsurface of the production device in the region of the displacement paths, it is preferably provided that adjusting elements are provided for height adjustment of the bearing surfaces of the sliding elements. Accordingly, the bearing surfaces can be adjusted in height to ensure a substantially flat course of the sliding bearing between the sliding elements and the Verschubbahnen. In a Verschubvorgang between the concreting station and the parking station, however, the sliding elements are displaceable substantially in the same height position on the Verschubbahnen. Accordingly, in particular no lifting presses for relocating the tunnel section before moving from the concreting station are required. Relocating the tunnel elements on lowering wedges after reaching the final position for the expansion of lifting presses is also advantageously not necessary.
Um die Tunnelabschnitte einzeln aus der Betonierstation zu entfernen, ist es vorteilhaft, wenn die Schubeinrichtung einen Linearantrieb zum Verschieben des im ausbetonierten Zustand vorliegenden Tunnelabschnitts von der Betonierstation in die Parkstation aufweist, wobei der Linearantrieb ein in Längsrichtung verschiebliches Krafteinleitungselement aufweist, das zwischen einer in eine Ausnehmung des Gleitelements eingreifenden Wirkstellung und einer außerhalb der Ausnehmung des Gleitelements angeordneten Einziehstellung verschwenkbar ist. Demnach ist das Krafteinleitungselements in der Wirkstellung innerhalb der Ausnehmung des Gleitelements anordenbar, so dass das Gleitelement durch Betätigung des Linearantriebs in Längsrichtung vorgeschoben wird. Der Linearantrieb weist bevorzugt einen hydraulischen Zylinder-Kolben-Antrieb auf, welcher an dem einen Ende mit dem Krafteinleitungselement und an dem anderen Ende mit einer ortsfesten Lagerstelle verbunden ist. Um den Linearantrieb einzufahren, wird das Krafteinleitungselement aus der Wirkstellung, in welcher das Krafteinleitungselement bevorzugt im Wesentlichen stehend angeordnet ist, in die Einziehstellung, in welcher das Krafteinleitungselement bevorzugt im Wesentlichen liegend angeordnet ist, verschwenkt.In order to remove the tunnel sections individually from the concreting station, it is advantageous if the pushing device has a linear drive for displacing the tunnel section present in the concreted state from the concreting station to the parking station, wherein the linear drive has a longitudinally displaceable force introduction element, which between one in one Recess of the sliding element engaging operative position and a arranged outside the recess of the sliding element retraction position is pivotable. Accordingly, the force introduction element can be arranged in the operative position within the recess of the sliding element, so that the sliding element is advanced by actuation of the linear drive in the longitudinal direction. The linear drive preferably has a hydraulic cylinder-piston drive, which is connected at one end to the force introduction element and at the other end to a stationary bearing point. To retract the linear drive, the force introduction element from the operative position, in which the force introduction element is preferably arranged substantially stationary, in the retraction position, in which the force introduction element is preferably arranged substantially lying, pivots.
Um den Tunnelabschnitt schrittweise zu verschieben, ist es günstig, wenn die Gleitelemente an der Unterseite mehrere in Längsrichtung beabstandete Ausnehmungen für das Krafteinleitungselement des Linearantriebs aufweist. Demnach kann das Gleitelement dadurch verschoben werden, dass das Krafteinleitungselement des Linearantriebs in einem ersten Schritt in der Wirkstellung angeordnet wird, in einem zweiten Schritt im Wesentlichen um den Abstand zwischen den benachbarten Ausnehmungen des Gleitelements ausgefahren wird, in einem dritten Schritt in die Einziehstellung verschwenkt wird, in einem vierten Schritt so weit eingefahren wird, dass das Krafteinleitungselement unter der in Längsrichtung folgenden Ausnehmung des Gleitelements angeordnet wird und in einem fünften Schritt wieder in die Wirkstellung verschwenkt wird. Diese Abfolge wird so lange wiederholt bis der Tunnelabschnitt aus der Betonierstation vollständig in die Parkstation verfahren wurde.Dabei wird auf einfache Weise der Tunnelabschnitt in der Betonierstation auf mehreren in Querrichtung voneinander beabstandeten Gleitelementen aufgelagert, wobei die Bodenschalung im ausbetonierten Zustand des Tunnelabschnitts aus einer angehobenen Betonierstellung in eine abgesenkte Ausschalstellung überführt wird, wobei der Tunnelabschnitt im ausbetonierten Zustand in der abgesenkten Ausschalstellung der Bodenschalung gemeinsam mit den Gleitelementen von der Betonierstation in die Parkstation verschoben wird.In order to move the tunnel section stepwise, it is advantageous if the sliding elements on the underside has a plurality of longitudinally spaced recesses for the force introduction element of the linear drive. Accordingly, the sliding element can be displaced by the fact that the force introduction element of the linear drive is arranged in the operative position in a first step, is extended in a second step substantially by the distance between the adjacent recesses of the sliding element, is pivoted in a third step in the retraction position is retracted so far in a fourth step that the force introduction element is arranged below the longitudinal direction of the recess of the sliding element and is pivoted in a fifth step back into the operative position. This sequence is repeated until the tunnel section from the concreting station has been completely moved into the parking station. The tunnel section in the concreting station is superimposed in a simple manner on a plurality of transversely spaced sliding elements, wherein the bottom form in the concreted state of the tunnel section from a raised concreting position is transferred in a lowered Ausschalstellung, the tunnel section is moved in the concreted state in the lowered Ausschalstellung the bottom formwork together with the sliding elements of the concreting in the parking station.
Durch die Verschiebung des Tunnelabschnitts auf den Gleitelementen wird vorteilhafterweise ermöglicht, dass der Tunnelabschnitt im ausbetonierten Zustand im Wesentlichen höhenunveränderlich auf den Gleitelementen von der Betonierstation in die Parkstation verschoben wird. In diesem Zusammenhang bedeutet "höhenunveränderlich", dass der Tunnelabschnitt vor Einleitung des Verschubvorgangs nicht auf Hubpressen umgelagert werden muss und im Wesentlichen in derselben Höhenposition wie in der Betonierstation in die Parkstation verschoben wird. Vorteilhafterweise können dadurch die beim Stand der Technik üblichen Hydraulikzylinder zum Umlagern des ausbetonierten Tunnelabschnitts eingespart werden. Andererseits können die Gleitelemente höhenjustierbar gelagert sein, um Veränderungen im Untergrund auszugleichen. Nach der Einstellung der Höhenposition der Lagerflächen können die Tunnelabschnitte jedoch ohne Anheben mittels Hubpressen aus der Betonierstation in die Parkstation verfahren werden.Due to the displacement of the tunnel section on the sliding elements, it is advantageously made possible for the tunnel section in the concreted state to be displaced substantially vertically on the sliding elements from the concreting station to the parking station. In this context, "height-invariant" means that the tunnel section does not have to be relocated to lifting presses prior to initiation of the transfer operation and is shifted into the parking station essentially at the same height position as in the concreting station. Advantageously, thereby the usual hydraulic cylinder in the prior art be saved for relocating the concreted tunnel section. On the other hand, the sliding elements can be mounted adjustable in height to compensate for changes in the ground. After setting the height position of the bearing surfaces, however, the tunnel sections can be moved without lifting by means of lifting presses from the concreting in the parking station.
Die stationäre Anordnung der Trageinrichtung ist vorzugsweise in Verbindung mit der zuvor beschriebenen Ausführung der Schubeinrichtung mit Gleitelementen vorgesehen, kann jedoch auch mit andersartigen Schubeinrichtungen, ohne Gleitelemente verwendet werden.The stationary arrangement of the carrying device is preferably provided in connection with the previously described embodiment of the sliding device with sliding elements, but can also be used with different pushing devices, without sliding elements.
Zu diesem Zweck kann beispielsweise ein im Stand der Technik bekanntes Verfahren eingesetzt werden, bei welchem das fertig betonierte Tunnelsegment auf hydraulischen Hubpressen verschoben wird. Bei diesem Herstellungsverfahren lagert der zu betonierende Tunnelabschnitt zunächst auf der Bodenschalung, bis der Tunnelabschnitt ausreichend ausgehärtet ist, um den Tunnelabschnitt ausschalen zu können. Um den Ausschalvorgang einzuleiten, wird der Tunnelabschnitt auf Hubpressen umgelagert, damit anschließend die Bodenschalung abgesenkt werden kann. Um auch die Bodenschalungselemente, die zwischen den Hubpressen eingebaut sind, ausschalen zu können, kann die Bodenschalung im Bereich der Verschubbahnen abgeklappt werden. Danach wird das fertig betonierte Tunnelsegment zusammen mit allen Hubpressen in die Endposition verschoben. Darüber hinaus können die Tunnelsegmente nach Erreichen der Endposition auf Absenkkeile umgelagert werden, um die Hydraulikzylinder vor dem Fluten der Tunnelabschnitte ausbauen zu können.For this purpose, for example, a known in the prior art method can be used, in which the finished concrete tunnel segment is moved to hydraulic lifting presses. In this manufacturing process, the tunnel section to be concreted initially rests on the bottom formwork until the tunnel section has hardened sufficiently to be able to shell out the tunnel section. To initiate the Ausschalvorgang, the tunnel section is relocated to lifting presses, so then the bottom formwork can be lowered. In order to be able to shell out the floor formwork elements that are installed between the lifting presses, the floor formwork can be folded down in the area of the displacement paths. Thereafter, the finished concrete tunnel segment is moved together with all lifting presses in the final position. In addition, the tunnel segments can be relocated after reaching the end position on lowering wedges to remove the hydraulic cylinder before flooding the tunnel sections can.
Gemäß einer bevorzugten Ausführungsform der Erfindung weist die Schalungsanordnung ein zwischen einer im Wesentlichen vertikal angeordneten Position und einer im Wesentlichen horizontal angeordneten geöffneten Position verschwenkbares Stirnschalungselement auf. Zum Einführen der Bewehrung zwischen die Innen- und Außenschalung kann daher das Stirnschalungselement hochgeschwenkt werden, wobei die Einführöffnung für die Bewehrung freigegeben wird. Zum Betonieren des Tunnelabschnitts wird das Stirnschalungssegment nach unten geschwenkt. Dadurch kann die Stirnschalung vorteilhafterweise besonders einfach und zeitsparend zwischen der geöffneten und der geschlossenen Position überführt werden. Zur Fertigung der Tunnelabschnitte ist es günstig, wenn das Stirnschalungselement im Wesentlichen U-förmig ausgebildet ist. Bei einem Tunnel mit mehreren Röhren können mehrere verschwenkbare Stirnschalungselemente vorgesehen sein.According to a preferred embodiment of the invention, the formwork arrangement has an end formwork element which can be pivoted between a substantially vertically arranged position and a substantially horizontally arranged open position. For introducing the reinforcement between the inner and outer formwork, therefore, the front formwork element can be swung up, wherein the insertion opening is released for the reinforcement. For concreting the tunnel section, the front formwork segment is pivoted downwards. This allows the Front formwork advantageously be transferred particularly simple and time-saving between the open and the closed position. To fabricate the tunnel sections, it is favorable if the end formwork element is substantially U-shaped. In a tunnel with several tubes, several pivotable front formwork elements can be provided.
Hinsichtlich einer konstruktiv einfachen, platzsparenden Ausführung ist es günstig, wenn die Betonierstation ein Stirnschalungsportal mit einem oberhalb einer Deckenschalung in Querrichtung angeordneten Portalelement aufweist, an welchem das Stirnschalungselement verschwenkbar angeordnet ist.With regard to a structurally simple, space-saving design, it is favorable if the concreting station has an end formwork portal with a portal element arranged transversely above a slab formwork, on which element the formwork element is pivotably arranged.
Gemäß einer alternativen Ausführung kann das Stirnschalungselement in Höhenrichtung verschieblich gelagert sein.
Gemäß einer weiteren alternativen Ausführung kann die Stirnschalung aus mehreren Schalungselementen aufgebaut werden, welche einzeln an der Schalungsanordnung montiert wurden.According to an alternative embodiment, the front formwork element can be mounted displaceably in the vertical direction.
According to a further alternative embodiment, the front formwork can be constructed from a plurality of formwork elements, which were individually mounted on the formwork arrangement.
Bei dem erfindungsgemäßen Herstellungsverfahren wird eine Trageinrichtung, bevorzugt ein Gitterträger, zur Abstützung einer Innenschalung der Schalungsanordnung vorgesehen, wobei die Trageinrichtung und die Innenschalung beim Verschieben des Tunnelabschnitts von der Betonierstation in die Parkstation im Wesentlichen stationär angeordnet werden. Demnach bleibt die Innenschalung, insbesondere auch die übrigen Schalungselemente der Schalungsanordnung, in der Betonierstation, während der Tunnelabschnitt im ausbetonierten Zustand in die Parkstation gefahren wird. Dadurch kann vorteilhafterweise eine Reinigung der Innenschalung früher durchgeführt werden.In the production method according to the invention, a carrying device, preferably a lattice girder, is provided for supporting an inner formwork of the formwork arrangement, wherein the carrying device and the inner formwork are arranged substantially stationary when moving the tunnel section from the concreting station into the parking station. Accordingly, the inner formwork, in particular the other formwork elements of the formwork arrangement, remains in the concreting station, while the tunnel section is driven in the concreted state into the parking station. As a result, a cleaning of the inner formwork can advantageously be carried out earlier.
Um einerseits die Zyklusdauer des erfindungsgemäßen Verfahrens zu verkürzen und andererseits den konstruktiven Aufwand zu verringern, ist es vorteilhaft, wenn zum Betonieren des Tunnelabschnitts eine Stirnschalung der Schalungsanordnung geschlossen wird, wobei die Trageinrichtung für die Innenschalung auf der Seite der Stirnschalung mittels eines Stützelements an einem Boden der Betonierstation abgestützt wird, wobei das Stützelement nach dem Verschieben des Tunnelabschnitts im ausbetonierten Zustand in die Parkstation und dem Öffnen der Stirnschalung in eine vom Boden der Betonierstation abgehobene Stellung gebracht wird, woraufhin eine Bewehrung durch eine an der Stirnseite der Betonierstation freigegebene Einführöffnung in die Schalungsanordnung eingeführt wird.On the one hand to shorten the cycle time of the method according to the invention and on the other hand to reduce the design effort, it is advantageous if an end shuttering of the formwork arrangement is concluded for concreting the tunnel section, wherein the support means for the inner formwork on the side of the front formwork by means of a support member on a floor the concreting station is supported, wherein the support element after moving the tunnel section in the concreted state in the parking station and the opening of the front formwork in a raised position is brought from the bottom of the concreting station, whereupon a reinforcement is introduced through a released on the front side of the concreting insertion opening in the formwork arrangement.
Nach dem Betonieren des Tunnelabschnitts und vor dem Verschieben des Tunnelabschnitts in die Parkstation wird bevorzugt ein in Längsrichtung versetzbares Auflagerelement, insbesondere ein Rollenbock, zwischen der Trageinrichtung und dem fertigen Tunnelabschnitt angeordnet. Das Auflagerelement wird bevorzugt an einem der Stirnschalung zugewandten Endbereich der Trageinrichtung platziert. Dadurch wird eine Auflagerung für die Trageinrichtung beim Verschieben des Tunnelabschnitts im fertig betonierten Zustand von der Betonierstation in die Parkstation vorgesehen. Die Trageinrichtung kann zudem mit einem weiteren versetzbaren Auflagerelement, insbesondere einem weiteren Rollenbock, an dem zuvor betonierten Tunnelabschnitt in der Parkstation abgestützt werden, bevor die Verschiebung des gerade ausbetonierten Tunnelabschnitts in die Parkstation eingeleitet wird.After concreting the tunnel section and before moving the tunnel section into the parking station, a longitudinally displaceable support element, in particular a roller block, is preferably arranged between the support device and the finished tunnel section. The support element is preferably placed on an end region of the support device facing the front formwork. As a result, a Auflagerung for the support device when moving the tunnel section is provided in the finished concrete state of the concreting in the parking station. The carrying device can also be supported with another displaceable support element, in particular a further roller block, on the previously concreted tunnel section in the parking station before the displacement of the tunnel section just concreted into the parking station is initiated.
