Description
Verfahren zum abschnittsweisen Auskleiden von Tunnels, Druckstollen und Schächten mit Beton Die Erfindung betrifft ein Verfahren zum abschnitts weisen Auskleiden von Tunnels, Druckstollen und Schächten mit Beton. Die Auskleidung dient bei einem Verkehrstunnel dem Schutz des durch den Tunnel flies- senden Verkehrs vor herabstürzenden Gesteinsmassen und bei Druckstollen sowie Schächten auch dem Schutz des Bauwerkes selbst, um z.B. Ausspülungen des Gesteins durch Druckwasser zu vermeiden. Ein Hauptproblem stellt häufig die Erzielung einer ausreichenden Wasser undurchlässigkeit der Auskleidung dar.
Um dieses Pro blem zu lösen, wurden bisher relativ aufwendige Betonier und Dichtverfahren verwendet, die einen entsprechend hohen Einsatz von Fachkräften und Geräten verlangen.
Beim erfindungsgemässen Verfahren wird dieser Auf wand dadurch verringert, dass in dem auszukleidenden Abschnitt der Baustelle eine diesem in Grösse und Form entsprechende Folie ausgespannt wird, dass unter der Folie die Schalung eingebracht und die Folie auf diese gelegt wird, und dass anschliessend der Raum zwischen dem umgebenden Gestein und der Folie durch Beton ausgefüllt wird.
Zur beispielsweisen Erläuterung des Verfahrens wird auf die Zeichnung Bezug genommen, in der Fig. 1 einen Querschnitt durch eine Tunnelbaustelle und Fig. 2 einen Schnitt durch die verwendete Folie zeigt. In Fig. 1 schliesst sich an das Gestein 1 eine Kopf schalung 2 für den zu betonierenden Tunnelabschnitt an. Eine Schalungsmaschine 3 trägt mittels einstellbarer Arme 4 einzelne Schalungselemente 5.
Die Schalungs- maschine 3 ist auf Schienen 7 auf der Sohle 8 des Tunnels verfahrbar. Zwischen Kopfschalung 2 und Schalungsele- menten 5 liegt eine Folie 6.
Fig. 2 zeigt einen Schnitt durch Folie 6, die mit der rauhen Seite 9 dem Beton zugewandt ist, und mit der glatten Seite 10 auf den Schalungselementen 5 aufliegt.
Zum Auskleiden eines Bauabschnittes wird zunächst die Folie 6 mit Hilfe eines Gerüsthimmels in einer Form und Grösse ausgespannt, die der inneren Gestalt des Tunnels entspricht. Nach dem Verbinden dieser Folie mit der Folie des vorhergehenden und bereits ausbetonierten Bauabschnittes wird die Schalungsmaschine 3 einge fahren. Der Gerüsthimmel für die Folie 6 wird entfernt, so dass sich die Folie auf die Schalungselemente 5 auf legt, die anschliessend mittels der einstellbaren Arme 4 in ihre genaue Stellung gebracht werden. Nach dem Auf setzen der Kopfschalung wird in den Zwischenraum zwischen Gestein 1 und Folie 6 Beton eingefüllt und ver dichtet.
Der Beton dringt in die ihm zugewandte rauhe Seite 9 der Folie 6 ein, wodurch die Folie nach dem Aushärten des Betons mit diesem unlösbar verbunden ist. Die Folie 6 kann aus verschiedenen Schichten hergestellt sein, die eine optimale Lösung der an die Folie gestellten Auf gaben gewährleisten. Die dem Beton zugewandte rauhe Seite 9 kann mit Vorsprüngen und Vertiefungen versehen sein, um die Verbindung mit dem Beton noch zu ver bessern. Die Dichtheit gegen den Durchtritt von Wasser braucht von dieser Schicht nicht aufgebracht zu werden, es kann im Gegenteil erwünscht sein, wenn in dieser Schicht sich ineinanderschliessende Hohlräume vorhan den sind, die z.B. einen Abfluss des aus dem Beton drin genden Wassers zur Tunnelsohle gestatten.
Zur Abdich tung gegen einen Wasserdurchtritt ins Tunnelinnere kann dann die nächste Schicht der Folie dienen. Diese oder eine weitere, nach dem Entfernen der Schalung 5 im Tun nel sichtbare Schicht lässt sich den besonderen Bedin gungen im Tunnelinneren anpassen, was z.B. ihr Aus sehen, ihre Widerstandsfähigkeit gegen aggressive Gase, usw. anbetrifft. Zudem wird durch die verschiedenen Schichten eine beim Einbringen der Schalung erwünschte grössere Steifigkeit der Folie erzielt, wodurch auf ein fache Weise während dieses Verfahrensabschnittes die Bildung von Falten in der Folie vermieden wird.
Die mit der Folie überzogene Innenverkleidung des Tunnels, Druckstollens oder Schachtes macht gegebenen falls einen Feinverputz oder besonderen Schutzanstrich überflüssig.
Zum Auskleiden von Druckstollen mit rundem oder elliptischem Querschnitt, z.B. zur Wasserführung in Kraftwerken, oder zum Auskleiden von senkrechten oder schrägen Schächten wird das Verfahren sinngemäss an gewendet.
Die Schalungsmaschine stützt sich hierbei in dem be reits ausgekleideten oder den übernächsten Bauabschnitt ab. Die Folie ist in diesem Fall für jeden Bauabschnitt ein Schlauchstück, das je nach den Bauverhältnissen schon vor dem Einbringen aus einem Stück Folie zu einem Schlauch verschweisst werden kann oder aber erst nach dem Einbringen in den Bauabschnitt, zusammen mit der Herstellung der Verbindung zur Folie des bereits fertig gestellten Abschnittes.
Method for lining tunnels, pressure tunnels and manholes in sections with concrete The invention relates to a method for lining tunnels, pressure tunnels and manholes in sections with concrete. In a traffic tunnel, the lining serves to protect the traffic flowing through the tunnel from falling rock masses, and in the case of pressure tunnels and shafts it also protects the structure itself, e.g. Avoid flushing the rock with pressurized water. A main problem is often the achievement of sufficient water impermeability of the lining.
To solve this problem, relatively complex concreting and sealing methods have been used, which require a correspondingly high level of use of skilled workers and equipment.
In the method according to the invention, this effort is reduced in that a film corresponding to this in size and shape is stretched out in the section of the construction site to be lined, that the formwork is introduced under the film and the film is placed on it, and that the space between the surrounding rock and the foil is filled with concrete.
To explain the method by way of example, reference is made to the drawing, in which FIG. 1 shows a cross section through a tunnel construction site and FIG. 2 shows a section through the film used. In Fig. 1, the rock 1 is followed by a head formwork 2 for the tunnel section to be concreted. A formwork machine 3 carries individual formwork elements 5 by means of adjustable arms 4.
The formwork machine 3 can be moved on rails 7 on the bottom 8 of the tunnel. A film 6 lies between the top formwork 2 and the formwork elements 5.
2 shows a section through foil 6, the rough side 9 of which faces the concrete and the smooth side 10 rests on the formwork elements 5.
To line a construction section, the film 6 is first stretched out with the aid of a framework in a shape and size that corresponds to the inner shape of the tunnel. After connecting this film with the film of the previous and already concreted construction section, the formwork machine 3 is driven. The framework for the film 6 is removed so that the film lies on the formwork elements 5, which are then brought into their exact position by means of the adjustable arms 4. After putting on the head formwork 6 concrete is poured into the space between rock 1 and foil and sealed ver.
The concrete penetrates into the rough side 9 of the foil 6 facing it, whereby the foil is permanently connected to the concrete after it has hardened. The film 6 can be made of different layers that ensure an optimal solution of the tasks placed on the film. The rough side facing the concrete 9 can be provided with projections and depressions in order to improve the connection with the concrete still ver. The tightness against the passage of water need not be applied by this layer; on the contrary, it may be desirable if there are interlocking cavities in this layer, e.g. Allow the water drin ing out of the concrete to drain to the tunnel floor.
The next layer of film can then serve to seal against water penetration into the tunnel interior. This or a further layer visible in the tunnel after the formwork 5 has been removed can be adapted to the special conditions inside the tunnel, which is e.g. their appearance, their resistance to aggressive gases, etc. In addition, the various layers achieve a greater rigidity of the film, which is desired when the formwork is being introduced, as a result of which the formation of folds in the film is avoided in a number of ways during this process section.
The inner lining of the tunnel, pressure tunnel or shaft covered with the foil makes fine plastering or special protective coating superfluous.
For lining pressure tunnels with a round or elliptical cross-section, e.g. The procedure is used analogously for water supply in power plants or for lining vertical or sloping shafts.
The formwork machine is supported here in the construction section that has already been lined or the next but one. In this case, the film is a piece of tubing for each construction section, which, depending on the construction conditions, can be welded to a tube from a piece of film before it is introduced or only after it has been introduced into the construction section, together with the connection to the film already completed section.
