Abstract

The invention relates to a waterproof seal for surfaces in hydraulic and civil engineering, especially for traffic routes, tunnels, embankments, bottoms, channels, dykes, dams, tubs, basins, basements, and underground parking garages. Said waterproof seal comprises a surface seal (3) which is particularly made of swelling fleece and lies on the surface (1) that is to be sealed. A cell structure (5) whose cell walls are provided with strips (5a) that have a sealing effect and are made especially of swelling fleece is arranged on top of the surface seal (3). The cell walls, above all the fleece strips, stand upright and/or at an angle on the surface seal (3) and are fixed to each other in a contacting, particularly an intersecting manner, while the cells (7) are filled with concrete or mortar.

Description

Die Erfindung betrifft eine wasserdichte Abdichtung von Flächen im Wasser- und Ingenieurbau insbesondere für Verkehrswege, Tunneln, Böschungen, Sohlen, Kanäle, Deiche, Dämme, Wannen, Becken, Kellern und Tiefgaragen mit einer Flächendichtung, die auf der abzudichtenden Fläche liegt.The invention relates to a watertight sealing of surfaces in water and engineering in particular for traffic routes, tunnels, embankments, soles, channels, dykes, dams, tubs, basins, cellars and underground garages with a surface seal, which is located on the surface to be sealed.

Bewässerungs- oder Kraftwerkskanäle, Deiche oder Dämme benötigen oftmals eine Abdichtung gegen Wasserverlust. Auch Abdichtungen von Tiefgaragen, Tunneln oder anderen unterirdischen Bauwerken benötigen zum Schutz der tragenden Betonkonstruktion vor Nässe und damit Beschädigung der tragenden Bewehrung durch Rost eine Abdichtung. Zur Anwendung kommen bitumhaltige Bahnen, auf Kautschukbasis oder solche aus Kunststoff wie Polyvinylchlorid (PVC), Polyethylen (PE), Polypropylen (PP) oder aus Gemischen dieser Produkte. Diese Abdichtungen benötigen wiederum einen Schutz vor Beschädigung durch darüber eingebauten Boden und/oder gegen den Untergrund.Irrigation or power plant canals, dykes or dams often require waterproofing against water loss. Also seals of underground garages, tunnels or other underground structures need to protect the load-bearing concrete structure from moisture and thus damage to the supporting reinforcement by rust sealing. Bituminous sheets, based on rubber, or plastics such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP) or mixtures of these products are used. These seals in turn require protection against damage by built-in soil and / or against the ground.

Die bekannten geotextilen Schutzvliese sind gegen mechanische Beschädigung bei späteren Baumaßnahmen, wie Aufgrabungen, nur bedingt geeignet. Für einen langfristigen Schutz werden sie deshalb durch eine Schicht aus Pflaster, Asphalt oder Beton ergänzt. Pflasterschichten sind unempfindlich und beanspruchen die Dichtung nicht durch Ausdehnung oder Kontraktion. Eine zusätzliche Abdichtungsfunktion erfordert aber eine teure und wartungsintensive Abdichtung der Fugen. Wegen der einfachen Beschaffung und einer wenig aufwendigen Einbautechnik haben sich Schutzschichten aus Beton durchgesetzt. Im Wasserbau übernimmt eine auf der Abdichtung verlegte Schutzschicht gegen Abrieb durch Geschiebe oder Eisgang gleichzeitig die Funktion einer Ballastschicht, die außerdem noch die schädliche UV-Strahlung abhält.The known geotextile protective fleeces are only partially suitable against mechanical damage during later construction measures, such as excavations. For long-term protection, they are therefore supplemented by a layer of paving, asphalt or concrete. Paving layers are insensitive and do not stress the seal by expansion or contraction. However, an additional sealing function requires an expensive and maintenance-intensive sealing of the joints. Because of the easy procurement and a little bit Expensive installation technology, protective layers of concrete have prevailed. In hydraulic engineering, a protective layer laid on the waterproofing seal at the same time takes on the function of a ballast layer against abrasion caused by debris or ice drift, which also prevents damaging UV radiation.

Beim direkten Einbau der Betonschicht auf einer Abdichtung wirken die temperaturbedingten Dehn- und Schrumpfbewegungen der Betonschicht negativ auf die Dichtung. Auf Böschungsflächen bereitet eine glatte Oberfläche der Dichtung Probleme, weil die Betonschicht abrutschen kann. Die Verwendung von Abdichtungen mit strukturierter Oberfläche verringert das Problem, ist aber technisch falsch, weil damit ein Formverbund mit der Betonschicht entsteht und die im Fugenbereich der Betonschicht auftretenden Längenänderungen die Ermüdung des Dichtungsmaterials verursacht.When directly installing the concrete layer on a seal, the temperature-induced expansion and shrinkage movements of the concrete layer have a negative effect on the seal. On embankment surfaces, a smooth surface of the seal causes problems because the concrete layer can slip off. The use of structured surface seals reduces the problem but is technically incorrect because it creates a mold bond with the concrete layer and the length changes occurring in the joint area of the concrete layer cause fatigue of the seal material.

Da der Einbau von Fugen in die Betonschicht teuer und zeitraubend ist, versucht man die Platten möglichst groß herzustellen. Damit steigt im Beton die Gefahr von Spannungsrissen oder Rissen durch Setzungen im Untergrund. Außerdem muss die Abdichtung der Fugen in der Betonschicht immer wieder erneuert werden, um die Dichtungsfunktion dauerhaft zu gewährleisten. Diese Wartung wird aber aus Kostengründen oftmals unterlassen. Damit kann die geringe Wasserdurchlässigkeit der Betonschicht als weitere Dichtungsschicht nicht angesetzt werden.Since the installation of joints in the concrete layer is expensive and time-consuming, trying to make the plates as large as possible. This increases the risk of stress cracks or cracks in subsurface concrete in concrete. In addition, the sealing of the joints in the concrete layer must be renewed again and again to ensure the sealing function permanently. However, this maintenance is often omitted for cost reasons. Thus, the low water permeability of the concrete layer can not be recognized as a further sealing layer.

Aus der US 4 572 705 A ist eine Abdichtung bekannt, bei der die Zellen mit Sand oder Schotter ausgefüllt werden, wobei hydraulische Bindemittel zum Einsatz kommen. Ferner ist es aus der EP 0 378 309 bekannt, mit einer Zellenstruktur aus Plastikstreifen die Oberfläche von Beton oder Erdreich zu begrenzen. Aus EP 0 005 238A ist ein sportflächenbelag bekannt, der die technischen Merkmale in Oberbegriff des Anspruchs 1 offenbart.From the US 4,572,705A a seal is known in which the cells are filled with sand or gravel, using hydraulic binders are used. Furthermore, it is from the EP 0 378 309 Known to limit the surface of concrete or soil with a plastic strip cell structure. Out EP 0 005 238A is a sports surface covering known, which discloses the technical features in the preamble of claim 1.

Aufgabe der Erfindung ist es, eine flexible, vollflächig verlegbare Abdichtung zu schaffen, die nicht verschweißt werden muss und deshalb auch unter ungünstigeren klimatischen Verhältnissen einfach verlegt werden kann Auch sollen auf dieser Dichtung in Böschungen Schutzschichten aus Beton ohne Schwierigkeiten verlegt werden können.The object of the invention is to provide a flexible, fully installable seal that does not need to be welded and therefore can be easily installed even under adverse climatic conditions also protective layers of concrete can be laid without difficulty on this seal in slopes.

Diese Betonschichten sollen kostengünstig in kleinere Flächen unterteilt werden, damit die temperaturbedingten Dehn- und Schrumpfbewegungen verringert und dadurch Spannungsrisse vermieden werden. Die Fugen sollen dauerhaft dicht hergestellt werden, wodurch ein doppellagiges Abdichtungssystem mit erhöhter Sicherheit entsteht.These concrete layers are to be divided into smaller areas at low cost, so that the temperature-induced expansion and shrinkage movements are reduced and thus stress cracks are avoided. The joints are to be permanently sealed, creating a double-layered sealing system with increased safety.

Diese Aufgaben werden erfindungsgemäß dadurch gelöst, dass über der Flächendichtung eine Zellenkonstruktion angeordnet ist, deren Zellenwände Streifen mit Dichtwirkung aus Quellvlies aufweisen, wobei die Zellenwände senkrecht und/oder schräg auf der Flächendichtung stehen und sich berührend insbesondere kreuzend aneinander befestigt sind, und dass die Zellen von Beton oder Mörtel ausgefüllt sind.These objects are achieved according to the invention in that a cell construction is arranged above the surface seal whose cell walls have strips with a sealing effect of swelling fleece, the cell walls standing vertically and / or obliquely on the surface seal and touching one another, in particular intersecting, and the cells filled with concrete or mortar.

Die erfindungsgemäße Abdichtung von Flächen im Wasser- und Ingenieurbau erfolgt somit mittels eines Dichtvlieses mit aufquellendem Material in einer Zellenkonstruktion. Eine solche Abdichtung lässt sich auch bei ungünstigen klimatischen Verhältnissen leicht verlegen ohne verschweißt werden zu müssen. Auf diese Abdichtung lassen sich sogar auf Böschungen Schutzschichten aus Beton leicht verlegen.The sealing of surfaces according to the invention in water and civil engineering is thus carried out by means of a sealing fleece with swelling material in a cell construction. Such a seal can be easily installed even in unfavorable climatic conditions without having to be welded. Protective concrete layers can easily be laid on this embankment, even on embankments.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen aufgeführt.Advantageous embodiments of the invention are listed in the subclaims.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung perspektivisch in einem Ausschnitt dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is shown in perspective in the drawing in a section and will be described in more detail below.

Zuerst werden auf einer bestehenden Abdichtung 2, die auf dem Untergrund 1 liegt und aus Beton, Asphalt, Bitumen oder einer Kunststoffbahn besteht, Bahnen aus einem bekannten Quellvlies verlegt und durch Vernähen zu einer vollflächigen Abdichtung der zu dichtenden Fläche verbunden.First, on an existing seal 2, which lies on the substrate 1 and consists of concrete, asphalt, bitumen or a plastic sheet, webs laid from a known swellable nonwoven and connected by sewing to a full-surface seal the surface to be sealed.

Das bevorzugte Flächengewicht des trockenen Quellvlieses beträgt 400 bis 1000 g/m2. Das Vlies aus synthetischen Fasern, bevorzugt aus Polypropylen oder Polyamid wird bei der Herstellung mit einem bei Wasserzutritt aufquellenden Polymer getränkt und anschließend getrocknet, wodurch eine Umhüllung aller Fasern entsteht. Mit dem gleichen Polymer ist auch der zum Vernähen der Einzelbahnen verwendete Faden ausgerüstet.The preferred basis weight of the dry swellable nonwoven is 400 to 1000 g / m 2 . The nonwoven fabric of synthetic fibers, preferably of polypropylene or polyamide is used in the production with a water ingress soaked up swelling polymer and then dried, creating a cladding of all fibers. With the same polymer and the thread used for sewing the single sheets is also equipped.

Die der künftigen Betonschicht zugewandte Seite des bahnenförmigen Quellvlieses 3 ist mit einer Filmschicht aus einem anderen Polymer überzogen, welches sich unter dem Einfluss der hohen Alkalität von frischem Beton nach wenigen Tagen auflöst. Mit dieser Beschichtung des Quellvlieses wird einmal die Aktivierung des Quellmittels durch den feuchten Beton vermieden. Zum anderen entsteht auch kein intensiver Verbund zwischen Beton und Vlies.The future concrete layer facing side of the sheet-like swellable nonwoven fabric 3 is coated with a film layer of another polymer, which dissolves under the influence of the high alkalinity of fresh concrete after a few days. With this coating of the swellable nonwoven, the activation of the swelling agent by the wet concrete is avoided. On the other hand, there is no intensive bond between concrete and fleece.

Aus einer gegen Verformung stabilisierten Variante des Quellvlieses werden Streifen 5a von 10 cm bis 50 cm Breite geschnitten. Die Streifen werden untereinander in regelmäßigen Abständen punkt- oder linienförmig so verbunden, dass mit einer senkrecht zu den Streifen aufgebrachten Zugkraft eine rauten- oder wabenförmige Struktur 5 mit einer zwischen den Vliesstreifen offenen Fläche von 0,2 bis 0,5 Quadratmetern entsteht, so dass eine mattenförmige Zellenkonstruktion 5 entsteht.From a stabilized against deformation variant of the swellable nonwoven strip 5a are cut from 10 cm to 50 cm in width. The strips are punctiform or linearly connected with one another at regular intervals so that a diamond-shaped or honeycomb-shaped structure 5 with a surface area of 0.2 to 0.5 square meters open between the nonwoven strips arises with a tensile force applied perpendicular to the strips a mat-shaped cell construction 5 is formed.

Die aus den Quellvliesstreifen 5a hergestellte Wabenmatte 5 wird entfaltet und auf der vollflächigen Abdichtung ausgelegt. Die offenen Flächen bzw. Zellen 7 oder Zwischenräume werden mit Beton 4 verfüllt, mit Rüttelbohlen verdichtet und die Betonoberfläche geglättet. Der Beton selbst ist weitgehend dicht. In die Fugen eindringendes Wasser aktiviert das Quellmittel in den Streifen 5a der Wabenmatte und führt zu einer Abdichtung der Fuge.The honeycomb mat 5 produced from the swellable nonwoven strip 5a is unfolded and laid out on the full-surface seal. The open areas or cells 7 or spaces are filled with concrete 4, compacted with Rüttelbohlen and smoothed the concrete surface. The concrete itself is largely dense. Penetrating water activates the swelling agent in the strip 5a of the honeycomb mat and leads to a sealing of the joint.

Das vollflächig unter der Betonschicht verlegte Quellvlies 3 wird durch Kondenswasserbildung aus der Feuchtigkeit des Bodens teilweise aktiviert und wirkt schon jetzt als zweite Dichtungsschicht. Entsteht aus irgendeinem Grund eine Beschädigung in der Betonschutzschicht, wird die Flächendichtung in diesern Bereich vollständig aktiviert und die Schadensstelle durch den Quelldruck des Vlieses vollständig geschlossen.The full-surface laid under the concrete layer swellable nonwoven fabric 3 is partially activated by condensation from the moisture of the soil and already acts as a second sealing layer. If, for any reason, damage occurs in the concrete protection layer, the surface seal in this area is fully activated and the damaged area is completely closed by the swelling pressure of the fleece.

Eine Unterläufigkeit der Betonschicht wird durch das örtlich aufgequollene Vlies ebenfalls vermieden.An inferiority of the concrete layer is also avoided by the locally swollen fleece.

Über der Betonfüllung 4 der Struktur 5 wird eine den Beton versiegelnde Schicht 6 aus Wachs insbesondere ein Wachsfilm oder eine chemische Versiegelung gelegt wird.Over the concrete filling 4 of the structure 5, a concrete sealing layer 6 of wax, in particular a wax film or a chemical seal, is laid.
