Abstract
Description
Im Wasserbau ist es häufig notwendig Betonbauwerke, wie beispielsweise Wasserzubringerkanäle für Wasserkraftwerke, Stauseemauern oder Schleusenanlagen, mit einer Kunststoffdichtungsbahn abzudichten.In hydraulic engineering, it is often necessary concrete structures, such as Wasserzubringerkanäle for hydroelectric power plants, reservoir walls or lock systems, sealed with a plastic waterproofing membrane.
Aus der DDR-Patentschrift DD 148 797 A sind zu diesem Zweck mit Vliesstoff kaschierte Kunststoffbahnen beschrieben, die zunächst mit ihrer Vliesstoffseite an den abzudichtenden Oberflächen der Bauwerke mittels geeigneter Klebstoffe, z.B. Zweikomponenten-Kleber auf PUR-Basis, überlappend angeklebt werden, wonach dann die Überlappungsbereiche der Kunststoffdichtungsbahnen, die nicht mit Vliesstoff kaschiert sind, verschweißt werden. In der Regel sind hierbei sehr aufwendige Haltekonstruktionen erforderlich, um die Kunststoffbahnen mit der gewünschten Festigkeit am Bauwerk anzukleben. Außerdem ist es u.a. notwendig, die mit Geovliesstoff kaschierten Kunststoffdichtungsbahnen mit entsprechenden Hilfsmitteln an die abzudichtenden Oberflächen zu drücken, bis der Kleber ausgehärtet ist. Anderenfalls ergeben sich aufgrund unterschiedlicher Ausdehnungsfaktoren von Kleberschicht und Kunststoffdichtungsbahn Verwerfungen bzw. Wellungen der angeklebten Kunststoffdichtungsbahnen, die nach dem Erhärten des Klebers nicht mehr beseitigt werden können.German Patent Specification DD 148 797 A describes plastic webs laminated with nonwoven fabric for this purpose, which are first provided with their nonwoven side to the surfaces of the structures to be sealed by means of suitable adhesives, e.g. Two-component adhesive PUR-based, are glued overlapping, after which the overlapping areas of the plastic gaskets, which are not laminated with nonwoven, are welded. As a rule, very expensive retaining structures are required in this case in order to glue the plastic sheets with the desired strength to the building. It is also u.a. necessary to press the Geovliesstoff laminated with plastic sealing sheets with appropriate tools to the surfaces to be sealed until the adhesive has cured. Otherwise, owing to different expansion factors of the adhesive layer and the plastic sealing strip, warping or curling of the glued-on plastic sealing strips, which can no longer be removed after the adhesive has hardened, results.
Aufgabe der vorliegenden Erfindung war es daher, ein Verfahren zur relativ einfachen und trotzdem sicheren Befestigung der mit Geovliesstoffen kaschierten Kunststoffdichtungsbahnen an den abzudichtenden Oberflächen der Bauwerke zu entwickeln, bei dem auf die Andrückhilfsmittel verzichtet werden kann, ohne dass Verwerfungen bzw. Wellungen der angeklebten Dichtungsbahnen auftreten.Object of the present invention was therefore to develop a method for relatively simple yet secure attachment laminated with geo-nonwovens plastic sealing sheets on the surfaces to be sealed of the structures, can be dispensed with the Andrückhilfsmittel without distortions or corrugations of the glued membranes occur ,
Diese Aufgabe wurde gemäß der vorliegenden Erfindung dadurch gelöst, dass man zunächst auf die abzudichtenden Oberflächen des Bauwerks, die bei alten Bauwerken zunächst gereinigt werden, einen thermoplastischen Geovliesstoff mittels eines Klebstoffes, vorzugsweise mittels eines Fliesenklebers, anklebt und nach der vollständigen Aushärtung des Klebers die mit einem thermoplastischen Geovliesstoff kaschierten Kunststoffdichtungsbahnen mit der angeklebten Geovliesstoffbahn verschweißt, wobei die Verschweißung über die beiden Geovliesstoffe miteinander erfolgt. Gleichzeitig oder danach findet die Verschweißung der Überlappungsbereiche der mit Geovliesstoff kaschierten Kunststoffdichtungsbahnen statt.This object has been achieved according to the present invention in that first adheres to the sealed surfaces of the structure, which are initially cleaned in old buildings, a thermoplastic Geovliesstoff by means of an adhesive, preferably by means of a tile adhesive, and after complete curing of the adhesive with a thermoplastic geo-nonwoven fabric laminated plastic sealing sheets with the bonded geotextile web welded, wherein the welding of the two geotextiles takes place together. At the same time or thereafter, the welding of the overlapping areas of the laminated Geovliesstoff plastic sealing sheets takes place.
In speziellen Fällen kann es dabei erwünscht sein, die Dichtwirkung der Kunststoffdichtungsbahn zusätzlich mittels einer mineralischen Dichtungsmatte abzusichern, beispielsweise mit einer Bentonit-Dichtungsmatte, wie sie in verschiedenen Ausführungsformen unter der geschützten Marke Bentofix® im Handel erhältlich und wie sie in der DE 37 04 503 C2 beschrieben sind. In solchen Fällen verschweißt man dann zunächst die Bentofix-Bahnen mit der an der abzudichtenden Oberfläche angeklebten Geovliesstoffschicht und verschweißt dann anschließend die Kunststoffdichtungsbahn mit der aufkaschierten Geovliesstoffseite mit der Bentonit-Dichtungsbahn.In special cases, it may be desirable to additionally secure the sealing effect of the plastic sealing strip by means of a mineral sealing mat, for example with a bentonite sealing mat, as commercially available in various embodiments under the protected brand Bentofix® and as described in DE 37 04 503 C2 are described. In such cases, one then first welds the Bentofix webs to the geo-nonwoven fabric layer adhered to the surface to be sealed, and then subsequently welds the plastic sealing web to the laminated geo-woven fabric side with the bentonite waterproofing web.
Die erfindungsgemäß verwendete Kunststoffdichtungsbahn besteht vorzugsweise aus einem thermoplastischen Kunststoff, insbesondere aus Polyvinylchlorid-P weich (PVC-P), Polyethylen hoher Dichte (PE-HD), Polyethylen niedriger Dichte (PE-LD), PE-C, ECB oder ENA.The plastic sealing strip used in the invention is preferably made of a thermoplastic material, in particular polyvinyl chloride P soft (PVC-P), high density polyethylene (PE-HD), low density polyethylene (PE-LD), PE-C, ECB or ENA.
Die erfindungsgemäß verwendete Kunststoffdichtungsbahn kann aber auch aus einem Elastomeren bestehen, beispielsweise aus IIR, EPDM, CR, NBR oder CSM.However, the plastic sealing strip used according to the invention can also consist of an elastomer, for example IIR, EPDM, CR, NBR or CSM.
Die erfindungsgemäß eingesetzte Kunststoffdichtungsbahn ist auf der später der angeklebten thermoplastischen Geovliesstoffbahn zugewandten Seite mit einer thermoplastischen Geovliesstoffschicht kaschiert, über die die Bindung mit der angeklebten Geovliesstoffbahn erfolgt, wobei sich die Kaschierung vorzugsweise nur bis zu dem Überlappungsbereich der Kunststoffdichtungsbahnen erstreckt, um eine direkte Verschweißung der Kunststoffdichtungsbahnen untereinander zu ermöglichen.The plastic sealing strip used according to the invention is laminated on the later side of the bonded thermoplastic Geovliesstoffbahn side facing a thermoplastic Geovliesstoffschicht over which the bond with the glued Geovliesstoffbahn takes place, wherein the lamination preferably extends only to the overlap region of the plastic sealing sheets to a direct welding of the plastic sealing sheets to allow each other.
Die Bentonit-Dichtungsbahn besteht vorzugsweise aus zwei Geotextilschichten und einer dazwischen befindlichen Bentonitschicht, wobei die Geotextilschichten, von denen mindestens eine ein Geovliesstoff ist, miteinander unter Einschluss der Bentonitschicht vernadelt oder vernäht sind.The bentonite liner is preferably comprised of two geotextile layers and a bentonite layer therebetween, wherein the geotextile layers, at least one of which is a geotextile, are needled or sewn together to include the bentonite layer.
Die Bentonit-Dichtungsbahn kann aber auch aus drei Geotextilschichten mit einer zusätzlichen Schwerstoffschicht bestehen, wobei alle Schichten miteinander vernadelt sind. Die zusätzliche Schwerstoffschicht besteht aus Quarzsand und/oder Quarzmehl. Derartige Matten werden natürlich nicht an senkrechten Wänden angebracht, sondern z.B. an Kanalsohlen und/oder Kanalböschungen.The bentonite geomembrane can also consist of three geotextile layers with an additional layer of heavy material, all layers are needled together. The additional layer of heavy material consists of quartz sand and / or quartz flour. Of course, such mats are not attached to vertical walls, but e.g. at channel bottoms and / or channel embankments.
Mit der der Kunststoffdichtungsbahn zugewandten Bentonitschicht erreicht man einen Selbstheilungseffekt für den Fall, dass die Kunststoffdichtungsbahn beschädigt wird. Das durch die "Verletzungsstelle" durch die Kunststoffdichtungsbahn eindringende Wasser bildet mit dem Bentonit eine aufgequollene, die Verletzungsstelle versiegelnde, praktisch wasserundurchlässige Bentonitschicht.With the bentonite layer facing the plastic sealing sheet, a self-healing effect is achieved in the event that the plastic sealing sheet is damaged. The penetrating through the "injury point" through the plastic waterproofing membrane water forms with the bentonite a swollen, the injury site sealing, virtually impermeable bentonite.
Die Verschweißung der mit Geovliesstoff kaschierten Kunststoffdichtungsbahn mit der vorher auf der abzudichtenden Oberfläche angeklebten Geovliesstoffbahn erfolgt vorzugsweise mittels Verfahren, bei denen man die zu verschweißenden Oberflächen mit offener Flamme oder mit Warmgas anschmilzt und dann diese angeschmolzenen Oberflächen zusammendrückt.The welding of the Geovliesstoff laminated plastic sealing sheet with the previously glued to the surface to be sealed Geovliesstoffbahn is preferably carried out by methods in which one melts the surfaces to be welded with an open flame or hot gas and then compresses these surfaces melted.
Gleichzeitig oder im Anschluß daran erfolgt die Verschweißung der Kunststoffdichtungsbahnen untereinander mit üblichen Verfahren, z.B. Heizkeilschweißen, die dem Fachmann bekannt sind. Vorzugsweise geht man dabei gemäß der vorliegenden Erfindung so vor, dass man entweder den gesamten Überlappungsbereich verschweißt oder dass man im Überlappungsbereich zwei parallel zueinander verlaufende Schweißnähte (Doppelnaht) unter Bildung eines Luft-Prüfkanals erzeugt, wobei die Schweißnähte vorzugsweise breite Schweißstreifen darstellen.At the same time or thereafter, the welding of the plastic sealing sheets with each other by conventional methods, e.g. Hot wedge welding, which are known in the art. Preferably, according to the present invention, the procedure is either to weld the entire overlap region or to produce two parallel welds (double seams) in the overlap region to form an air test channel, the welds preferably forming wide weld strips.
Die Verlegung sowohl der Geovliesstoffbahn als auch der Kunststoffdichtungsbahn erfolgt nach den dem Fachmann bekannten Verfahrensweisen, wobei sowohl in der Ebene als auch an Böschungen die Verlegung beispielsweise mittels Traverse mit Bagger oder Seilwinde oder mittels selbst-fahrender Rahmenkonstruktion erfolgt, in die die Kombi-Kunststoffdichtungsbahn eingelegt und dann über Ketten-, Seil- oder Zahnradantrieb abgerollt wird.The laying of both the geotextile web and the plastic waterproofing membrane is carried out according to the procedures known in the art, both in the plane and on embankments laying, for example by means of traverse with excavator or winch or by means of self-propelled frame construction, in which the combination plastic sealing sheet inserted and then unrolled via chain, rope or gear drive.
