- Fig. 1 shows a tunnel tube 10, in which by a circular formwork device 12 a full formwork is to be formed.
- the circular formwork device 12 includes a support structure 14 carried by a tunneling machine, for example, on which a plurality of shuttering elements 16a, 16b, 16c, 16d are circumferentially abutted against each other, so that four formwork elements 16a to 16d form a closed circuit for completely shuttering the tube 10 in one Make operation.
- Each formwork element 16a to 16d has a certain length in the axial direction of the tunnel, for example 1 to 3 m, so that a plurality of formwork elements 16a to 16d can be arranged in the axial direction one behind the other according to the length of the tunnel tube to be boarded.

In this way, a very high quality tunnel formwork is created with relatively little effort, any remaining inclusions or bubbles in the concrete in the lower area below the formwork part does not affect the visual appearance and performance characteristics of the tunnel wall in the bottom area.
- the Fig. 3 to 5 show once again the sequence of a manufacturing process of a tunnel tube of a circular formwork device according to the Fig. 1 and 2 ,
- each of the formwork elements 16a to 16d consists of a central fixed portion 22, at the outer ends of which in each case a movable portion 24, 26 is articulated via joints 25, 27 pivotally.
- Each of the sector form elements 16a to 16d is constructed in this way.
- the middle fixed portions 22 are connected via support receptacles 17 with the support structure 14, which includes hydraulic support cylinder 28 through which the sector shuttering elements 16a to 16d can be moved towards each other or away from each other by means of the support receptacles 17 of their fixed portions 22, ie in the direction on the wall of the tunnel tube 10 or away from it.
- Fig. 3 shows the circular formwork device 12 after the central positioning in the tunnel tube, for example on a tunneling machine.

In this way, a coherent formwork full circle is formed. Between the movable portions 24, 26 facing sector formwork elements 16a to 16d, an inclined abutment surface 29 is formed, which is inclined relative to the corresponding adjacent shuttering surface at an angle of 25 to 60 °, in particular at an angle of 45 °, resulting in a better tightness between brings the movable portions 24, 26 of the adjacent sector shuttering elements 16a - 16d with it.
- Fig. 4 shows the situation already after the filling of the concrete, wherein the formwork part 18 firmly abuts against the formwork surface 30 of the lower formwork element 16d, so that the surface of the formwork part 18 after removal of the formwork elements 16a to 16d, as shown in FIG Fig. 5 is shown aligned with the surface 34 of the formwork part 18.
- the formwork part 18 thus remains after removal of the circular formwork device 12 as an integral part of the concrete formwork 20 in the tunnel tube 10.
- a very high-quality and non-porous floor area is formed by the formwork part 18, especially in the much used floor area of the tunnel.
- Fig. 6 to 8 show an alternative embodiment of the invention, in which the formwork member 18 itself forms a lower formwork element and thus covers the bottom sector of the tunnel in a sector of about 20 to 40 °.
- the circular formwork device 40 off Fig. 6 includes a support structure 42 with a vacuum lifting device 44, which has a vacuum suction surface 46 in order to suck the formwork part 18 over a large area.
- the circular formwork device 40 further includes in the circumferential direction of the tunnel tube 10 three adjacent formwork elements 48a to c (the non-imaged region is mirror-inverted), namely two lateral formwork elements 48a, 48c and an upper formwork element 48b, which are preferably pivotally connected to each other via hinges 49.
- the hinges 49 may also be formed by bolts which are inserted into aligned holes of their connecting portions after the positioning of the formwork elements 48a, 48b.
- the joint can be released by pulling the bolts, so that the formwork elements 48a, b can be handled separately before and after the production of the formwork.
- the two lateral formwork elements 48a, 48c each have at their lower edge a movable portion 50, which, as it is in Fig. 7 can be seen, with a pressure member 51 rests against the upper side of the formwork part 18 and thus the formwork part 18 is supported towards the inside of the tunnel.
- the formwork part 18 is supported on the supporting structure 42 preferably at two points by vertical support elements 52, 54 that can be extended in length relative to one another.
- Fig. 8 shows the cross section after the casting of the gap between the shuttering surfaces 30, the formwork elements 48a to 48c and the formwork part 18 and the wall of the tunnel tube 10, wherein the thus formed tunnel wall 20 is formed in its bottom region to the tunnel center through the formwork part 18.

Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Ausschalung einer insbesondere kreisrunden Tunnelröhre. Die Tunnelröhre kann auch andere Querschnittsflächen haben wie ellipsoid oder rechteckig. Derzeit werden für die Ausschalung von Tunneln Schalungsvorrichtungen verwendet, die Schalungselemente mit einer zylindersegmentartigen Schalungsfläche aufweisen. Die Schalungsflächen der Schalungselemente werden einer Tunnelwand zugewandt angeordnet und anschließend wird der Zwischenraum zwischen der Schalungsfläche der Schalungselemente und der Tunnelwand mit Beton vergossen. Auf diese Weise wird im Stand der Technik eine Tunnelröhre mit einer Schalung versehen. Ein Problem bei dem Vergießen des Betons besteht darin, dass an bestimmten Stellen, insbesondere im Bodenbereich der Tunnelröhre eingeschlossene Blasen im Beton nach oben steigen und dann an der Oberfläche der Schalung sichtbar sind. Derartige Blasen können nur mit hohem Aufwand eliminiert werden können, so dass entweder Blasen im Beton verbleiben, die dann an die Oberfläche steigen oder zur Entgasung des Betons in dem Bereich ein extrem hoher Aufwand betrieben werden muss.The present invention relates to a method and a device for shuttering a particular circular tunnel tube. The tunnel tube may also have other cross-sectional areas, such as ellipsoidal or rectangular. Currently shuttering devices are used for the shuttering of tunnels, which have shuttering elements with a cylinder-segment-like formwork surface. The shuttering surfaces of the shuttering elements are arranged facing a tunnel wall and then the space between the shuttering surface of the shuttering elements and the tunnel wall is cast with concrete. In this way, a tunnel tube is provided with a formwork in the prior art. One problem with potting the concrete is that bubbles trapped in certain locations, particularly in the floor area of the tunnel tube, rise in the concrete and are then visible on the surface of the formwork. Such bubbles can be eliminated only with great effort, so that either bubbles remain in the concrete, which then rise to the surface or for degassing of the concrete in the area an extremely high cost must be operated.
Es ist Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zur Ausschalung einer Tunnelröhre zu schaffen, die mit vergleichsweise geringem Aufwand über die gesamte Tunnelschalung eine gute Schalungsqualität liefern.It is an object of the present invention to provide a method and a device for Ausschalung a tunnel tube, which provide a good formwork quality with relatively little effort over the entire tunnel formwork.
Die Aufgabe wird durch ein Verfahren gemäß Anspruch 1 und eine Vorrichtung gemäß Anspruch 6 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der nebengeordneten Ansprüche. Vorteilhafte Ausführungen der Erfindung sind weiterhin in der Beschreibung und in den Zeichnungen beschrieben.The object is achieved by a method according to claim 1 and a device according to claim 6. Advantageous developments of the invention are the subject of the independent claims. Advantageous embodiments of the invention are further described in the description and in the drawings.
Erfindungsgemäß wird insbesondere im unteren Bereich der Schalungsvorrichtung wenigstens ein Schalungsteil als verlorene Schalung der Tunnelwand zugewandt angeordnet. Beim Vergießen des Zwischenraums zwischen den Schalungselementen bzw. dem Schalungsteil und der Tunnelwand wird das Schalungsteil als verlorene Schalung mit dem Beton integriert verbunden und bildet somit die Oberfläche der Schalung insbesondere im unteren Bereich der Tunnelröhre. Das Schalungsteil kann somit unter günstigsten Bedingungen in einer Fabrik vorfabriziert werden und ist damit frei von irgendwelchen Einschlüssen oder Luftblasen. Das Schalungsteil kann zum Beispiel aus einem UHPC-Beton (Ultrahochleistungsbeton) bestehen. In der fertiggestellten Tunnelschalung bildet somit dieses Schalungsteil in einem Bereich, insbesondere dem Bodenbereich, die Oberfläche der Tunnelschalung. Da dieses Schalungsteil in der Herstellung sehr hochwertig ist, wird somit auch in schwierig handzuhabenden Bereichen, wie z.B. den Bodenbereich eine Schalung mit einer blasenfreien Oberfläche erreicht, und das Problem von Blasen oder Einschlüssen insbesondere im unteren Bereich der Tunnelröhre spielt keine Rolle mehr, da die Oberfläche der Schalung durch das Schalungsteil gebildet wird.According to the invention, at least one formwork part, in particular in the lower region of the formwork device, is arranged as a permanent formwork facing the tunnel wall. When casting the gap between the formwork elements or the formwork part and the tunnel wall, the formwork part is integrated as a permanent formwork with the concrete connected and thus forms the surface of the formwork in particular in the lower part of the tunnel tube. The formwork part can thus be prefabricated under favorable conditions in a factory and is thus free from any inclusions or air bubbles. The formwork part may for example consist of a UHPC concrete (ultra-high performance concrete). In the finished tunnel formwork thus forms this Formwork part in an area, in particular the floor area, the surface of the tunnel formwork. Since this formwork part is very high-quality in production, thus, even in difficult-to-handle areas, such as the bottom area a formwork with a bubble-free surface is achieved, and the problem of bubbles or inclusions especially in the lower part of the tunnel tube does not matter because the Surface of the formwork is formed by the formwork part.
Das Schalungsteil ist demgemäß vorzugsweise entsprechend der Form der Tunnelröhre als kreissegmentförmiges Teil ausgebildet, welches einen gewissen Winkelabschnitt im Bodenbereich der Tunnelröhre abdeckt, zum Beispiel 5 bis 90°, insbesondere 8 bis 45°, insbesondere um die 10° bis 25°. Es gibt prinzipiell zwei unterschiedliche Möglichkeiten, das Schalungsteil im unteren Bereich der Tunnelröhre anzuordnen. Die erste Möglichkeit besteht darin, das Schalungsteil an dem z.B. dem Tunnelboden zugewandten Schalungselement anzulegen, so dass sich beim Vergießen des Bereichs zwischen Tunnelwand bzw. Tunnelboden und Schalungselement das Schalungsteil mit dem eingegossenen Beton verbindet und nach dem Entfernen der Schalungselemente das Schalungsteil die Schalung des Tunnels im Bodenbereich bildet.Accordingly, the formwork part is preferably formed according to the shape of the tunnel tube as a circular segment-shaped part which covers a certain angle section in the bottom region of the tunnel tube, for example 5 to 90 °, in particular 8 to 45 °, in particular around 10 ° to 25 °. There are basically two different ways to arrange the formwork part in the lower part of the tunnel tube. The first possibility is to connect the formwork part to the e.g. the formwork element facing the tunnel floor, so that when casting the area between the tunnel wall or tunnel floor and formwork element, the formwork part connects with the cast concrete and after removal of the formwork elements, the formwork part forms the formwork of the tunnel in the bottom area.
Eine andere Möglichkeit besteht darin, das Schalungsteil selbst als Schalungselement zu verwenden, so dass z.B. im Bodenbereich der Tunnelröhre das Schalungsteil selbst ein Schalungselement bildet, was in Verbindung mit den anderen Schalungselementen im Umfang der Tunnelröhre eine vollumfängliche Schalungsvorrichtung bildet, so dass die Tunnelröhre im Vollkreis verschalt werden kann. Wie bereits gesagt, ist eine Kreisform optional, es können auch elliptische Tunnelformen oder gar rechteckige Tunnelquerschnitte durch die Erfindung hergestellt werden.Another possibility is to use the formwork part itself as formwork element, so that e.g. in the bottom region of the tunnel tube, the formwork part itself forms a formwork element, which forms in connection with the other formwork elements in the scope of the tunnel tube a vollumfängliche formwork device, so that the tunnel tube can be boarded in the full circle. As already stated, a circular shape is optional; elliptical tunnel shapes or even rectangular tunnel cross sections can also be produced by the invention.
In einer vorteilhaften Weiterbildung des erfindungsgemäßen Verfahrens wird das Schalungsteil mit einer Vakuumhebevorrichtung auf seine Endposition herabgelassen, woraufhin das Schalungsteil durch die Schalungsvorrichtung relativ zu den Schalungselementen in Position gehalten wird. Anschließend wird der Zwischenraum zwischen den Schalungselementen bzw. dem Schalungsteil und der Tunnelwand mit Beton vergossen, wobei eine innige Verbindung zwischen dem Schalungsteil und dem Beton entsteht. Danach werden die Schalungselemente entfernt und das Schalungsteil bildet dann insbesondere im Bodenbereich einen die Oberfläche aufweisenden Bestandteil der Tunnelschalung. Mit einer derartigen Vakuumhebevorrichtung lässt sich das Schalungsteil insbesondere aus UHPC-Beton trotz eines Gewichts von mehreren 100 kg bis Tonnen sehr gut handhaben als auch durch Wegnahme des Vakuums lösen. Die Vakuumhebevorrichtung hat vorzugsweise eine großflächige Vakuumanlagefläche, so dass bereits vergleichsweise geringe Unterdrücke zur Erzielung der erforderlichen Ansaugkraft ausreichen. Bei einer Vakuumkontaktfläche von 1 m2 reicht zum Beispiel ein Druck von 0,1 bar aus, um ein Schalungsteil mit einem Gewicht von 1 t zu heben.In an advantageous development of the method according to the invention, the formwork part is lowered to its end position with a vacuum lifting device, whereupon the formwork part is held in position by the formwork device relative to the formwork elements. Subsequently, the gap between the formwork elements or the formwork part and the tunnel wall is potted with concrete, wherein an intimate connection between the formwork part and the concrete is formed. Thereafter, the formwork elements are removed and the formwork part forms then in particular in the bottom area a surface having the component of the tunnel formwork. With such a vacuum lifting device, the formwork part, in particular made of UHPC concrete can handle very well despite a weight of several 100 kg to tons and solve by removing the vacuum. The vacuum lifting device preferably has a large-area vacuum contact surface, so that already comparatively low Sufficient vacuum to achieve the required suction force. With a vacuum contact surface of 1 m 2, for example, a pressure of 0.1 bar is sufficient to lift a formwork part weighing 1 ton.
Die Erfindung betrifft ebenfalls eine Schalungsvorrichtung zur Ausschalung einer Tunnelröhre, die eine Tragstruktur zum Abstützen mehrerer Schalungselemente der Schalungsvorrichtung umfasst, Die Schalungsvorrichtung ist insbesondere als Rundschalungsvorrichtung mit rundem, insbesondere kreisrundem Querschnitt ausgebildet. Die Schalungselemente, insbesondere Sektorschalungselemente, decken aneinandergesetzt zumindest einen Teil des Umfangs des Tunnels, ab und sind zeitweise, das heißt während des Bildens der Tunnelschalung, an der Tragstruktur abgestützt sind. Die Schalungsvorrichtung enthält ein unteres Schalungsteil als verlorene Schalung, welches von der Tragstruktur und/oder von wenigstens einem angrenzenden Schalungselement während des Bildens der Schalung in Position gehalten wird, so dass vorzugsweise die dem Tunnelinnenraum zugewandte Oberfläche des Schalungsteils mit der der Tunnelwand zugewandten Schalungsfläche der Schalungselemente fluchtet. Das Schalungsteil ist dazu konzipiert, sich beim Vergießen der Tunnelröhre mit dem Schalungsbeton innig zu verbinden und dabei einen Teil der Tunnelschalung zu bilden. Das Schalungsteil bildet somit während der Verschalung der Tunnelröhre einen Teil der Schalungsvorrichtung, während es nach Fertigstellung der Schalung einen Teil der Schalung bildet.The invention also relates to a shuttering device for shuttering a tunnel tube, which comprises a support structure for supporting a plurality of shuttering elements of the shuttering device. The shuttering device is designed in particular as a circular shuttering device with a round, in particular circular cross-section. The formwork elements, in particular sector formwork elements, cover at least part of the circumference of the tunnel, placed against one another, and are supported on the support structure temporarily, that is to say during the formation of the tunnel formwork. The formwork device contains a lower formwork part as permanent formwork, which is held in position by the support structure and / or at least one adjoining formwork element during the formation of the formwork, so that preferably the surface of the formwork part facing the tunnel interior is in contact with the formwork surface of the formwork elements facing the tunnel wall flees. The formwork part is designed to intimately connect with the concrete during casting of the tunnel tube, thereby forming part of the tunnel formwork. The formwork part thus forms a part of the formwork device during the casing of the tunnel tube, while it forms part of the formwork after completion of the formwork.
Vorzugsweise umfasst mindestens eines der Schalungselemente, vorzugsweise alle Schalungselemente einen festen Abschnitt und wenigstens einen bewegbaren Abschnitt, der relativ zu dem festen Abschnitt zwischen einer geschlossenen Schalungsstellung und einer offenen Montagestellung bewegbar, insbesondere schwenkbar ist, wobei in der Schalungsstellung die Schalungsflächen des festen und bewegbaren Abschnitts fluchten. Eine aus derartigen Schalungselementen gebildete Schalungsvorrichtung kann durch die Bewegung der entsprechenden beweglichen Abschnitte leicht zur Bildung einer geschlossenen Schalung montiert und aus der Schalungsstellung wieder durch Bewegung der beweglichen Abschnitte in eine Montagestellung bewegt werden, aus welcher die Schalungselemente von der gebildeten Tunnelschalung abgelöst werden können.Preferably, at least one of the formwork elements, preferably all formwork elements comprises a fixed portion and at least one movable portion which is movable relative to the fixed portion between a closed mold position and an open mounting position, in particular pivotable, wherein in the formwork position, the shuttering surfaces of the fixed and movable portion aligned. A shuttering device formed from such formwork elements can be easily mounted by the movement of the corresponding movable portions to form a closed formwork and moved from the formwork position again by moving the movable sections in a mounting position, from which the formwork elements can be detached from the formed tunnel formwork.
Vorzugsweise weist jedes Schalungselement in Umfangsrichtung einen festen Abschnitt und an seinen beiden einander abgewandten Enden jeweils mindestens einen bewegbaren Abschnitt auf. Auf diese Weise liegen sich bei aneinandergesetzten Schalungselementen immer die beiden entgegengesetzten bewegbaren Abschnitte zweier benachbarter Schalungselemente einander zugewandt und können durch gegensätzliche Bewegung leicht voneinander gelöst werden.Preferably, each formwork element in the circumferential direction on a fixed portion and at its two opposite ends in each case at least one movable portion. In this way, the two are always in juxtaposed formwork elements opposite movable sections of two adjacent formwork elements facing each other and can be easily solved by opposing movement of each other.
In einer vorteilhaften Weiterbildung der Erfindung ist der bewegbare Abschnitt wenigstens eines Schalungselements, insbesondere Sektorschalungselements, konzipiert, das Schalungsteil in seiner Schalungsstellung zur Tunnelmitte hin abzustützen, wodurch vermieden wird, dass nach dem Einfüllen von Beton in den Zwischenraum zwischen dem Schalungsteil und der Tunnelwand das Schalungsteil durch den Beton nach innen gedrückt wird. Alternativ oder zusätzlich kann das Schalungsteil auch durch die Tragstruktur der Schalungsvorrichtung in seiner Schalungsstellung gehalten werden.In an advantageous development of the invention, the movable section of at least one formwork element, in particular sector formwork element, designed to support the formwork part in its formwork position towards the tunnel center, thereby avoiding that after the filling of concrete in the space between the formwork part and the tunnel wall, the formwork part pushed inward by the concrete. Alternatively or additionally, the formwork part can also be held in its formwork position by the supporting structure of the formwork device.
Die Tragstruktur weist aus diesem Grund vorzugsweise hydraulische Teleskopstreben auf, mittels derer die Schalungselemente und/oder die Schalungselemente und das Schalungsteil gegeneinander in Richtung der Tunnelwand und von dieser weg bewegt werden können. Die Teleskopstreben sind dabei vorzugsweise zum Zentrum der Tunnelröhre hin durch einen Support, z.B. die Tunnelmaschine abgestützt.For this reason, the support structure preferably has hydraulic telescopic struts, by means of which the formwork elements and / or the formwork elements and the formwork part can be moved in the direction of the tunnel wall and away from it. The telescopic struts are preferably towards the center of the tunnel tube through a support, e.g. supported the tunnel machine.
Vorzugsweise weist die Tragstruktur eine Hebevorrichtung auf, um das Schalungsteil in seine Schalungsposition zu bewegen. Eine derartige Hebevorrichtung kann insbesondere als Vakuumhebevorrichtung ausgebildet sein, die mit vergleichsweise geringem Aufwand ein lösbares Transportieren der teilweise schweren Schalungsteile auf einfache Weise ermöglicht.Preferably, the support structure has a lifting device to move the formwork part to its formwork position. Such a lifting device can be designed in particular as a vacuum lifting device, which allows a relatively easy way a releasable transporting the partially heavy formwork parts in a simple manner.
Vorzugsweise ist das Schalungsteil als ein vorgefertigtes UHPC-Betonteil ausgebildet, welches mit hoher Qualität und porenfrei in einer Fabrik vor der Montage in der Tunnelröhre hergestellt werden kann. Dieses Schalungsteil bildet nach Fertigstellung der Schalung ein sehr hochwertiges Oberflächenteil des Tunnel, vorzugsweise den Tunnelboden nach dem Beenden des Schalungsvorgangs.Preferably, the formwork part is designed as a prefabricated UHPC concrete part, which can be produced with high quality and non-porous in a factory before mounting in the tunnel tube. This formwork part forms after completion of the formwork a very high quality surface part of the tunnel, preferably the tunnel floor after the completion of the shuttering process.
Das Schalungsteil überdeckt vorzugsweise zum Tunnelboden hin einen Sektor von 5 bis 90°, insbesondere 7 bis 45°, insbesondere 10 bis 25°, vorzugsweise um die 10°. Auf diese Weise wird ein sehr hochwertiger porenfreier Tunnelboden gebildet, was für die weiteren Arbeiten im Tunnel als auch für die Endverwendung des Tunnels wichtig ist.The formwork part preferably covers the tunnel floor towards a sector of 5 to 90 °, in particular 7 to 45 °, in particular 10 to 25 °, preferably by 10 °. In this way, a very high quality pore-free tunnel floor is formed, which is important for the further work in the tunnel as well as for the end use of the tunnel.
Vorzugsweise sind in der Schalungsvorrichtung die Sektorschalungselemente oder das Sektorschalungselement im Bodenbereich durch das Schalungsteil ersetzt, so dass das Schalungsteil im Bodenbereich selbst ein Schalungselement bildet.In the formwork device, the sector formwork elements or the sector formwork element in the floor area are preferably replaced by the formwork part, so that the formwork part in the floor area itself forms a formwork element.
Vorzugsweise sind die Schalungselemente an ihren einander zugewandten Kanten über Gelenke verbunden oder verbindbar, um so eine zusammenhängende Schalung zu errichten, die leicht zusammengesetzt aber auch wieder abgebaut werden kann. Die Gelenke können auch durch Bolzen gebildet sein, die z.B. nach dem Positionieren der Schalungselemente in ihrer Schalungsstellung in fluchtende Löcher ihrer Verbindungsabschnitte gesteckt werden, womit die Schalungselemente zum Bilden einer zusammenhängenden Schalung miteinander verbunden sind. Das so gebildete Gelenk kann durch Ziehen der Bolzen gelöst werden, so dass die Schalungselemente vor und nach dem Herstellen der Schalung separat gehandhabt werden können.Preferably, the formwork elements are connected at their edges facing each other via joints or connectable so as to build a coherent formwork, which can be easily assembled but also degraded again. The joints may also be formed by bolts, e.g. after positioning the shuttering elements in their shuttering position are inserted into aligned holes of their connecting sections, whereby the shuttering elements are interconnected to form a coherent formwork. The joint thus formed can be released by pulling the bolts, so that the formwork elements can be handled separately before and after the production of the formwork.
Um eine Gesamtschalung einer Tunnelröhre zu bilden, bilden die Schalungselemente oder die Schalungselemente und das Schalungsteil zusammen einen Vollkreis. Dieser Vollkreis zwischen den der Schalungsfläche der Schalungselemente bzw. der Schalungsfläche der Schalungselemente bzw. des Schalungsteils und der Tunnelwand wird dann mit Beton verfüllt, wodurch sich eine geschlossene Tunnelschalung bildet.To form an overall formwork of a tunnel tube, form the formwork elements or the formwork elements and the formwork part together a full circle. This full circle between the shuttering surface of the formwork elements or the formwork surface of the formwork elements or the formwork part and the tunnel wall is then filled with concrete, which forms a closed tunnel formwork.
Die Schalungsvorrichtung ist vorzugsweise an der Rückseite einer Tunnelmaschine mit einer Vortriebseinrichtung und einem an der Vortriebseinrichtung gehaltenen Tunnelfräskopf angeordnet, so dass die Schalung direkt nach der Tunnelfräsung durchgeführt werden kann, selbstverständlich in definierten Vortriebsabständen von z.B. 2 bis 10 m. Nach der Ausschalung ist der Tunnel sicher betretbar und für weiter Arbeiten zugänglich.The formwork device is preferably arranged on the rear side of a tunneling machine with a propulsion device and a tunneling milling head held on the propulsion device, so that the formwork can be carried out directly after tunneling, of course at defined propulsion distances of e.g. 2 to 10 m. After the shuttering, the tunnel is safely accessible and accessible for further work.
Vorzugsweise ist die Tragstruktur der Schalungsvorrichtung von der Tunnelmaschine , insbesondere der Vortriebseinrichtung gehalten ist, so dass sie zentriert in der gerade gefrästen Tunnelröhre abgestützt werden kann. Daher benötigt man neben der ohnehin notwendigen Tunnelmaschine keine zusätzliche Abstützung für die Tragstruktur in der Tunnelröhre, um die Schalung zentriert im Tunnel anzuordnen, ohne an der Tunnelwand abgestützt zu sein.Preferably, the supporting structure of the formwork device is held by the tunneling machine, in particular the propulsion device, so that it can be supported centered in the straight milled tunnel tube. Therefore, in addition to the already necessary tunneling machine no additional support for the support structure in the tunnel tube needed to center the formwork arranged in the tunnel, without being supported on the tunnel wall.
Vorzugsweise bilden die Schalungselemente oder die Schalungselemente und das Schalungsteil einen Vollkreis, so dass erfindungsgemäß eine komplette Tunnelröhre gefertigt werden kann.Preferably, the formwork elements or the formwork elements and the formwork part form a full circle, so that according to the invention a complete tunnel tube can be manufactured.
Vorzugsweise ist das Schalungsteil im unteren Sektor des Schalungsvorrichtung angeordnet, wo die höchste Beanspruchung vorliegt und/oder wo die höchsten Anforderungen an die Oberflächenbeschaffenheit der Tunnelwandung vorliegen.Preferably, the formwork part is arranged in the lower sector of the formwork device, where the highest stress is present and / or where the highest demands are made on the surface condition of the tunnel wall.
Vorzugsweise hat das Schalungsteil eine geringere Stärke hat als die zur erstellende Tunnelschalung. Auf diese Weise kann das Schalungsteil während der Herstellung der Tunnelröhre an seiner der Röhre abgewandten Außenseite von Beton hinterfüllt werden und somit einen integrativen Bestandteil der Tunnelschalung bilden.Preferably, the formwork part has a lower thickness than the tunnel formwork to be created. In this way, during the manufacture of the tunnel tube, the formwork part can be backfilled with concrete on its outside facing away from the tube and thus form an integral part of the tunnel formwork.
Vorzugsweise sind wenigstens zwei Schalungselemente gelenkig miteinander verbunden und können daher einfacher an der Baustelle montiert werden.Preferably, at least two formwork elements are hinged together and therefore can be easily mounted on the site.
Selbstverständlich können über den Umfang verteilt mehrere Schalungsteile als verlorene Schalung verwendet werden. Die Schalungselemente können ein- oder mehrteilig sein.Of course, distributed over the circumference several formwork parts can be used as a lost formwork. The formwork elements can be one or more parts.
