Description

Die Erfindung betrifft eine Vorrichtung zum Abdichten der Wandungen von Ingenieurbauwerken aus Beton, vorzugsweise von unterirdischen Tunnelbauwerken, wobei ein Verlegewagen mit einem schwenkbaren Andrückbalken zum Einsatz kommt.The invention relates to a device for sealing the walls of engineering structures made of concrete, preferably of underground tunnel structures, wherein a laying carriage with a pivotable pressure bar is used.

Derartige Isolierungen werden derzeit fast ausschließlich zwischen einem äußeren Gewölbe aus Spritzbeton, geschaltem Ortsbeton oder Betontübbingen und einem eigentlich tragenden Innengewölbe eingebaut. Für Folienisolierungen im Tunnel- und Stollenbau werden vornehmlich Folien in einer Stärke von 1,0 bis 3 mm verwendet. Eine große Schwierigkeit bereitet dabei das Befestigen der Folien an der sehr oft nassen Innenwand. Für die Befestigung der Folie an der äußeren Auskleidung aus Beton, Spritzbeton oder Naturstein wurden bereits mehrere Lösungen durch Anhängen mit Hilfe von Rondellen oder Schienen oder durch Aufspannen bzw. durch Einschießen von Nägeln gefunden. Die Folien werden oft geschädigt und sind nicht mehr dicht gegen Sicker- und/oder Druckwasser.Such insulations are currently installed almost exclusively between an outer vault of shotcrete, geschaltem local concrete or Betontübbingen and actually supporting inner vault. For film insulation in tunnels and galleries mainly foils with a thickness of 1.0 to 3 mm are used. A great difficulty prepares the fixing of the films on the very often wet interior wall. For the attachment of the film to the outer lining of concrete, shotcrete or natural stone several solutions have already been found by attaching by means of rondelles or rails or by clamping or by shooting nails. The films are often damaged and are no longer tight against seepage and / or pressurized water.

Bei einem weiteren Verfahren werden Stahlgitterbögen in einem bestimmten Abstand zur Betondecke abgespannt, an denen die Folie befestigt wird.In another method steel lattice arches are tensioned at a certain distance from the concrete floor, where the film is attached.

Alle diese Verfahren sind arbeitsaufwendig und qualitativ wenig zufriedenstellend.All of these methods are labor intensive and poor in quality.

Der derzeitige Stand der Technik wird darüber hinaus durch verschiedenste Verfahrensvarianten des bekannten "Hot-Melt-Verfahrens" gebildet. Dabei werden unterschiedliche Folien bzw. Folienbahnen auf der Betonwandung durch das Aufbringen von Heissleim befestigt ( CH 441 417 , CH 652 448 , CH 560 811 ).The current state of the art is also formed by a variety of process variants of the known "hot melt process". Different films or film webs are attached to the concrete wall by the application of hot glue ( CH 441 417 . CH 652 448 . CH 560 811 ).

In einer besonderen Ausführungsform dieses Hot-Melt-Verfahrens wird in EP 1 192 332 B1 eine Vorrichtung und ein dazugehöriges Verfahren beschrieben, wobei auf einem speziellen Transportgestell ein Arbeitsspeicher mit Heissleim und die Folienbahnen zum Einbauort transportiert werden. Die Folienbahnen werden nach dem Aufbringen von Heißleim an der Wandung über einen Leimbalken und eine Anpressrolle befestigt.In a particular embodiment of this hot-melt method is in EP 1 192 332 B1 describes a device and an associated method, wherein on a special transport frame a working memory with hot glue and the film webs are transported to the installation site. The film webs are attached after the application of hot glue to the wall via a glue bar and a pressure roller.

Auch diese Verfahren sind kostenaufwendig.These methods are also expensive.

Letztlich ist eine Dichtungsbahn für unterirdische Bauwerke und dergleichen mit einer wenigstens einschichtigen Kunststoffbahn bekannt, wobei die Dichtungsbahn auf einer Flachseite zumindest abschnittsweise mit einer Geotextilschicht verbunden ist ( EP 1 057 940 A1 und EP 1 493 899 A1 ). Die Dichtungsbahn kommt teilweise mehrschichtig, jedoch als mehrschichtige Variante vorgefertigt zum Einsatz und wird in einem Zuge durch Verklebung auf die Tunnelwandung oder eine Vorsatzschicht aufgebracht.Finally, a geomembrane for underground structures and the like with an at least single-layered plastic web is known, wherein the geomembrane is connected at least in sections to a geotextile layer on a flat side ( EP 1 057 940 A1 and EP 1 493 899 A1 ). The geomembrane is partly multilayer, but prefabricated as a multilayer variant used and is applied in one go by gluing on the tunnel wall or a facing layer.

Allen vorgenannten Dichtungsbahnen und Verfahren ist gemeinsam, dass Sie auf die Tunnelwandung vorzugsweise über Heißleimverklebung aufgebracht werden bzw. die Heißleimtechnik verwenden.All of the aforementioned geomembranes and methods have in common that they are preferably applied to the tunnel wall via hot glue bonding or use the hot glue technique.

Darüber hinaus ist eine Abdichtung von Wandungen gegen Druck- und Sickerwasser durch das Aufbringen einer mehrschichtigen Dichtungsbahn aus Schaumkunststoff und PVC bekannt, die das Befestigen dieser einen Verbundschicht auf der Betonwandung durch Aufschmelzen realisiert ( DE 28 37 333 ). Das Aufschmelzen erfolgt mittels Heißgas oder offener Flamme, wobei die Dichtungsbahn über das Erhitzen der PVC-Schicht an der Betonwandung direkt und in einem einstufigen Verfahren aufgeschmolzen wird. Dabei wird die PVC-Schicht und die Schaumstoffschicht relativ oft verletzt, so dass sich Schmelzlöcher bilden, durch die Wasser über die Schaumstoffschicht und die PVC-Schicht in den Beton eindringt und durch diesen langsam hindurchdringt.In addition, a sealing of walls against pressure and seepage by the application of a multilayer waterproofing membrane made of plastic foam and PVC is known, which realizes the attachment of this one composite layer on the concrete wall by melting ( DE 28 37 333 ). The melting takes place by means of hot gas or open flame, wherein the geomembrane is melted by heating the PVC layer on the concrete wall directly and in a one-step process. In this case, the PVC layer and the foam layer is relatively often injured, so that form melt holes through which water penetrates through the foam layer and the PVC layer in the concrete and penetrates through it slowly.

Aus der EP 1 600 603 A1 ist ein Verfahren und eine Vorrichtung zum Abdichten der Wandung von Ingenieurbauwerken bekannt, wobei mindestens ein Geotextil und eine Kunststoffbahn mittels Heißluft auf die Tunnelwandung aufgeschmolzen werden. Der dort erwähnte Verlegewagen wird jedoch konstruktiv nicht näher ausgeführt.From the EP 1 600 603 A1 a method and a device for sealing the wall of engineering structures is known, wherein at least one geotextile and a plastic web are melted by means of hot air to the tunnel wall. However, the laying carriage mentioned there is structurally not specified.

Die Hebelarme sind vorzugsweise als Parallelogramm-Hebelarme ausgeführt.The lever arms are preferably designed as a parallelogram lever arms.

Die Zylinder des Hauptauslegers des Verlegearmsystems sind nur gemeinsam ansteuerbar und mit den notwendigen Sicherheitsventilen ausgestattet.
Die gleichmäßige Bewegung der beiden Zylinder wird mit dem in den Zylindern integrierten Wegmesssystem überwacht. Die beiden Zylinder für die Parallelogramm-Hebelarme sind einzeln ansteuerbar, damit Ungleichheiten des Felsens angesteuert werden können.
The cylinders of the main boom of the laying arm system can only be controlled together and equipped with the necessary safety valves.
The smooth movement of the two cylinders is monitored by the position measuring system integrated in the cylinders. The two cylinders for the parallelogram lever arms are individually controllable, so that inequalities of the rock can be controlled.

Die Hebel mit den Anpressrollen werden mittels Luft-Balgzylindern an die Felswand gepresst. Die Balgzylinder sind parallel geschaltet, können jedoch zusätzlich mit einem Handhebelventil ein- und ausgeschaltet werden. Die Druckluftversorgung erfolgt über einen zentralen Kompressor.The levers with the pressure rollers are pressed against the rock wall by means of air bellows cylinders. The bellows cylinders are connected in parallel, but can additionally be switched on and off with a hand lever valve. The compressed air supply takes place via a central compressor.

Der Verlegewagen weist eine SPS-Steuerung auf. Die Steuerung ist so aufgebaut, dass im Handbetrieb jede Funktion einzeln angesteuert werden kann. Als weitere Möglichkeit ist ein Automatikbetrieb vorgesehen.

Das Zentralstahlrohr ist über Kardangelenke am Auslegerarmsystem befestigt. Die Kardangelenke schaffen im Zusammenhang mit dem Auslegerarmsystem die Möglichkeit, Ungenauigkeiten der abzudichtenden Felswand auszugleichen.The central steel tube is attached to the boom arm system via cardan joints. The cardan joints create in connection with the boom system the possibility to compensate for inaccuracies of the sealed rock wall.
