Description

Auskleidungsmaterial für Kanal- und/oder Rohrleitungen, Kanal- und/oder Rohrauskleidung und Herstellverfahren  Lining material for sewer and / or piping, sewer and / or pipe liners and manufacturing processes
Die vorliegende Erfindung betrifft ein neues schlauchförmiges Auskleidungsmaterial, insbesondere ein schlauchförmiges Auskleidungsmaterial für sanierungsbedürftige Kanal- und/oder Rohrleitungen als Grundmaterial sowie eine aus dem Auskleidungsmaterial hergestellte Rohrauskleidung. The present invention relates to a novel tubular lining material, in particular a tubular lining material for rehabilitation-requiring ductwork and / or pipelines as a base material, as well as a pipe liner made of the lining material.
Kanäle oder Rohrleitungen, insbesondere unterirdische Rohre, wie sanitäre Entwässerungsrohre, Regenwasserrohre, Wasserleitungen und Gasleitungen, die zur Leitung von Flüssigkeiten und Gasen verwendet werden, benötigen Reparaturen aufgrund von Undichtigkeiten und des nachfolgenden Durchsickems von Medien oder sie benötigen Reparaturen aufgrund von Verschleiß. Es ist bekannt, dass im Bundesland Bayern zum heutigen Stichtag ca. 12.500 km Kanalleitungen kurzfristig saniert werden müssen, wobei Hausanschlüsse noch nicht berücksichtigt sind. Ducts or pipelines, particularly underground pipes such as sanitary drainage pipes, rainwater pipes, water pipes and gas pipes used to convey liquids and gases, require repairs due to leaks and subsequent leakage of media, or require repair due to wear. It is known that in the federal state of Bavaria about 12,500 km of sewer pipes must be rehabilitated at the current deadline at short notice, with house connections not yet taken into account.
Eine erste Möglichkeit der Sanierung stellt der Austausch von defekten Rohrabschnitten dar. Wenn jedoch die Rohrleitungen im Erdreich oder im Mauerwerk verdeckt verlegt sind, stellt das zum Austausch erforderliche Freilegen der Rohrleitungen, zum Beispiel durch Erdaushebung etc., eine zeit- und kostenintensive Maßnahme dar. Ein anderer Ansatz besteht daher darin, die Rohrleitungen zu sanieren, ohne dass diese freigelegt oder ausgetauscht werden müssen, indem die Rohrleitungen nachträglich mit einer Auskleidung versehen werden. A first possibility of remediation is the replacement of defective pipe sections. However, if the pipes in the ground or in the masonry are laid hidden, the need for replacement exposing the pipes, for example by Erdaushebung etc., represents a time and cost-intensive measure. Another approach is therefore to rehabilitate the pipelines without having to uncover or replace them by retrofitting the piping with a liner.
In DE 197 18 655 C2 wird die Verwendung von Strickschläuchen, insbesondere von PolyesteiTundgestricken, für die grabenlose Kanalsanierung im sogenannten „Schlauch- Liner- Verfahren'' beschrieben. Bei diesem sogenannten „Schlauch-Liner- Verfahren" wird das zu sanierende Rohr mit einem Schlauch ausgekleidet, der aus einem Kunststoffschlauch wird das Schlauchsystem mittels eines druckbetriebenen Inversionsverfahrens in den zu sanierenden Kanal eingedrückt. Unter Beibehaltung des Drucks, der das Andrücken der imprägnierten Auskleidung an die Rohrwandung gewährleistet, wird das Harz ausgehärtet, wobei kalt- und warmaushärtende Systeme zum Einsatz kommen. Nachteilig ist bei diesem Verfahren unter Verwendung von Strickschläuchen, insbesondere von Polyesterrundgestricken, die geringe Statik, der hohe Kriechmodul und die nicht ausreichende Medien-Beständigkeit. DE 197 18 655 C2 describes the use of knit hoses, in particular of polyester knits, for trenchless sewer rehabilitation in the so-called "hose liner method". In this so-called "hose liner process", the pipe to be rehabilitated is lined with a hose made of a plastic hose the tube system is pressed by means of a pressure-driven inversion process in the channel to be rehabilitated. Maintaining the pressure that will allow the impregnated liner to press against the pipe wall, the resin is cured using cold and thermosetting systems. A disadvantage of this method using knitted hoses, in particular of polyester core knitted fabrics, the low static, the high creep modulus and the insufficient media resistance.
Zur Auskleidung längerer Rohrabschnitte sind auch Systeme bekannt, welche aus einem Polyesternadelfilzschlauch, einem Zwei-Komponenten-Epoxidharz, mit dem der Filzschlauch getränkt wird, und einem Silikon-Kalibrierschlauch bestehen. Der Kalibrierschlauch wird in vorbestimmter Länge in den Nadelfilzschlauch eingezogen und am Ende verschlossen. Nach dem Tränken des Nadelfilzschlauches mit Epoxidharz wird das System in die Rohrleitung mittels einer Seilwinde eingezogen. Anschließend wird der Kalibrierschlauch mit Druckluft beaufschlagt, wodurch der getränkte Filzschlauch eng an die Rohrleitung angedrückt wird. Nach dem Aushärten des Harzes wird der Druck abgelassen und der Kalibrierschlauch entfernt. Es bleibt ein Filz/Harz-Verbundstoffrohr in der Rohrleitung zurück. Nachteilig bei der Verwendung von Nadelfilzen, insbesondere Polyesternadelfilzen, ist die sehr geringe Statik und ein hoher Kriechmodul sowie die zu geringe Medienbeständigkeit. For lining longer pipe sections, systems are also known which consist of a polyester needle felt hose, a two-component epoxy resin with which the felt hose is impregnated, and a silicone calibration hose. The calibration tube is drawn in a predetermined length in the needle felt hose and closed at the end. After impregnating the needle felt hose with epoxy resin, the system is drawn into the pipe by means of a winch. Then the calibration hose is pressurized with compressed air, whereby the impregnated felt hose is pressed close to the pipe. After curing of the resin, the pressure is released and the calibration tube is removed. A felt / resin composite tube remains in the pipeline. A disadvantage of the use of needle felts, in particular polyester needle felts, is the very low static and a high creep and the too low media resistance.
Ein schlauchförmiges Auskleidungsmaterial für Rohrleitungen, die Krümmungen und gebogene Abschnitte enthalten können, ist auch in DE 35 05 107 offenbart. Dieses Auskleidungsmaterial besteht aus einem schlauchförmigen gestrickten oder gewebten Textilmantel, der mit einer luftundurchlässigen Beschichtung aus einem flexiblen Kunstharz beschichtet ist. Zur Auskleidung eines Rohres wird dieses Auskleidungsmaterial im Umstülpverfahren unter Druckbeaufschlagung in das Rohr eingeführt, so dass die beschichtete Seite auf der Rohrinnenwand zum liegen kommt und die Kunstharzbeschichtung die innerste Schicht des ausgekleideten Rohres bildet. A tubular lining material for pipelines, which may contain bends and bent sections, is also disclosed in DE 35 05 107. This lining material consists of a tubular knitted or woven textile sheath which is coated with an air-impermeable coating of a flexible synthetic resin. In order to line a pipe, this lining material is inserted in the pipe in the everting process under pressure, so that the coated side comes to lie on the pipe inner wall and the synthetic resin coating forms the innermost layer of the lined pipe.
Der Textilmantel ist ein kompaktes, nicht komprimierbares Gewebe oder Gestrick aus gekräuselten Polybutylenterephthalatfasern (Kettfasern) und anderen Synthesefasern (Schußfasern). Sowohl der Textilmantel als auch das zu dessen Beschichtung verwendete Kunstharz sind biaxial dehnbar, wodurch bei der Druckbeaufschlagung des in das Rohr eingebrachten Auskleidungsmaterials eine Anpassung des Auskleidungsmaterials an die Form der Rohrleitung erfolgt, insbesondere in Krümmungen und gebogenen Abschnitten. Dadurch soll eine Faltenbildung vermieden werden. The textile cover is a compact, non-compressible fabric or knitted fabric crimped polybutylene terephthalate fibers (warp fibers) and other synthetic fibers (weft fibers). Both the textile sheath and the resin used for its coating are biaxially stretchable, whereby when lining the lining material introduced into the tube, an adaptation of the lining material to the shape of the pipeline takes place, in particular in curvatures and curved sections. This is to avoid wrinkling.
Die bisherigen Studien der Erfinder der vorliegenden Anmeldung haben ergeben, dass auch ein Auskleidungsmaterial, das aus einem biaxial dehnbaren Textilmantel besteht, welches mit einem flexiblen Kunstharz beschichtet ist, eine Auskleidung von komplizierten Rohrabschnitten, wie beispielsweise Krümmungen von 90°, nicht in befriedigender Weise faltenfrei erzielt. Vielmehr führt ein derartiger Verbundwerkstoff im Bereich von starken Krümmungen wie beispielsweise 90° zu Faltenbildung im Innenbogen bzw. zur Ablösung des Auskleidungsmaterials von der Innenwand des Rohres im Außenbogen. Previous studies by the inventors of the present application have shown that even a lining material consisting of a biaxially stretchable textile sheath coated with a flexible synthetic resin does not satisfactorily wrinkle a lining of complicated tubulars, such as curves of 90 ° achieved. Rather, such a composite in the region of strong bends such as 90 ° leads to wrinkles in the inner bow or for detachment of the lining material from the inner wall of the tube in the outer bow.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Auskleidungsmaterial zu entwickeln und herzustellen, das sich zur faltenfreien Auskleidung von sanierungsbedürftigen Rohrleitungen eignet, die eine komplizierte Struktur aufweisen, insbesondere Krümmungen von 90°, Änderungen des Rohrleitungsinnendurchmessers entlang der auszukleidenden Rohrleitung (Dimensionssprung) oder verwinkelte Teilstücke mit komplizierter Geometrie im Bereich von Verzweigungsanschlüssen. The invention is therefore based on the object to develop and produce a lining material that is suitable for wrinkle-free lining of rehabilitation-requiring piping, which have a complicated structure, in particular curvatures of 90 °, changes in the pipe inner diameter along the pipeline to be lined (dimensional jump) or twisted sections with complicated geometry around branch connections.
Weiterhin soll das Auskleidungsmaterial einen ausreichenden Verbund von Harz- und Trägermaterial gewährleisten. Die Rückstände der Harze sollen keine Abflusshindernisse mehr bilden und Materialablösungen sollen nicht mehr auftreten. Furthermore, the lining material should ensure a sufficient combination of resin and support material. The residues of the resins should no longer form any flow obstacles and material detachment should no longer occur.
Die obigen Aufgaben konnten erfindungsgemäß gelöst werden durch Bereitstellen eines Auskleidungsmaterials für die Innenseite einer Rohrwand, insbesondere eines Kanal- oder Abwasserrohres, umfassend The above objects could be achieved according to the invention by providing a lining material for the inside of a pipe wall, in particular a sewer or sewer pipe comprising

- mindestens eine Beschichtung, die aus einem Kunstharz besteht, ausgewählt aus der Gruppe, die aus Polyurethan, Polyvinylchlorid, Polyacrylat, Polyolefm, besteht und die auf mindestens einer Seite der Textilschicht vorgesehen ist gegebenenfalls einen um den beschichteten und gegebenenfalls kaschierten Schlauch aus textilem Trägermaterial koaxial und frei beweglich angeordneten Kalibrierschlauch.  - At least one coating consisting of a synthetic resin selected from the group consisting of polyurethane, polyvinyl chloride, polyacrylate, Polyolefm, and which is provided on at least one side of the textile layer optionally coaxially around the coated and optionally laminated tube of textile substrate and freely movable arranged calibration tube.
Im Gegensatz zu dem nahtlosen Strickschlauchmaterial des Standes der Technik enthält das erfindungsgemäße Auskleidungsmaterial am Zusammenstoßen der beiden Enden der Textilschicht Nähte, so dass ein Schlauch resultiert, wobei die Nähte insbesondere auch lasergeschweißt sein können und auch eine geeignete Nahtabdeckung aufweisen. In contrast to the seamless knit tube material of the prior art, the lining material according to the invention contains seams at the collision of the two ends of the textile layer, resulting in a tube, wherein the seams may in particular also be laser-welded and also have a suitable seam covering.
Bei den ECR-Glasfasern handelt es ich bevorzugt um Fasern mit einer erhöhten KoriOsionsbeständigkeit (ECR: E-Glass Corrosion Resistant). Alternativ können auch andere Glasfasern oder sonstige Fasern verwendet werden. The ECR glass fibers are preferably fibers with increased corrosion resistance (ECR: E-Glass Corrosion Resistant). Alternatively, other glass fibers or other fibers may be used.
Die obigen Aufgaben konnten weiterhin erfindungsgemäß gelöst werden durch das Bereitstellen eines beschichteten Auskleidungsmaterials, wobei die Beschichtung aus dem Kunstharz eine Beschichtungsdicke zwischen etwa 100 μηι und etwa 400 μηι, insbesondere zwischen etwa 100 μιη und etwa 250 μηι, aufweist und insbesondere mittels einer Düse oder in Form einer Kunstharzfolie, aufgebracht ist. Bei einer bevorzugten Ausführungsform ist mindestens eine Kaschierung oder Beschichtung aus einem Schaumstoff auf mindestens einer Seite der Textilschicht vorgesehen. The above objects could also be achieved according to the invention by providing a coated lining material, wherein the coating of the resin has a coating thickness between about 100 μηι and about 400 μηι, in particular between about 100 μιη and about 250 μηι, and in particular by means of a nozzle or in Form of a synthetic resin film is applied. In a preferred embodiment, at least one lamination or coating of a foam is provided on at least one side of the textile layer.
Bei einer weiteren bevorzugten Ausführungsform ist der Schaumstoff auf der der Textiisschicht abgewandten Seite einer Schaumstoffschicht angeordnet, wobei die Schaumstoffschicht auch eine Beschichtung aufweisen kann, die aus einem Kunstharz besteht, das insbesondere ausgewählt ist aus der Gruppe, die aus Polyurethan, Polyvinylchlorid, Polyacrylat, Polyolefm besteht Die Kaschierung oder Beschichtung aus dem Schaumstoff weist bevorzugt eine Kaschierungsdicke bzw. Beschichtungsdicke von zwischen 2 mm und 5 mm auf. In a further preferred embodiment, the foam is disposed on the side of a foam layer facing away from the textile layer, wherein the foam layer may also have a coating consisting of a synthetic resin, which is in particular selected from the group consisting of polyurethane, polyvinyl chloride, polyacrylate, Polyolefm The lamination or coating of the foam preferably has a lining thickness or coating thickness of between 2 mm and 5 mm.
Bei dem Schaumstoff handelt es sich bevorzugt um einen offenzelligen bzw. offenporigen Schaumstoff, welcher beispielsweise durch nachträgliche Sprengung erhalten werden kann. Da die Zellwände eines solchen Schaumstoffes nicht geschlossen sind, kann dieser definiert, gleichmäßig Flüssigkeiten aufnehmen. Dies ermöglicht das homogene Imprägnieren des beschichteten Auskleidungsmaterials mit einer härtbaren Harzzusammensetzung. The foam is preferably an open-cell or open-cell foam, which can be obtained, for example, by subsequent blasting. Since the cell walls of such a foam are not closed, this can be defined, absorb liquids evenly. This enables the homogeneous impregnation of the coated lining material with a curable resin composition.
Der Schaumstoff umfasst bevorzugt ein Polyolefm, insbesondere Polypropylen. Ein solcher Schaumstoff kann beispielsweise hergestellt werden, indem aufgeschmolzenes Polyolefm in einem Extruder mit einem Treibmittel, beispielsweise einem Treibgas, versetzt wird. Die Schmelze expandiert dann beim Austritt aus einer Düse. The foam preferably comprises a polyolefin, in particular polypropylene. Such a foam can be prepared, for example, by adding molten polyolefin in an extruder with a blowing agent, for example a propellant gas. The melt then expands upon exiting a nozzle.
Weiterhin ist es beispielsweise möglich, eine Schaumstoffbeschichtung in situ auf die Textilschicht aufzubringen, indem eine Schaumbeschichtung mit einer geeigneten Polymerdispersion durchgeführt wird. Diese Dispersion wird bevorzugt mit einem Schaummixer mit Luft beladen. Durch geeignete Wahl der Verfahrensparameter können Beschichtungen aus kleinzelligen offenporigen Schäumen erzeugt werden. Die obigen Aufgaben konnten weiterhin erfindungsgemäß gelöst werden durch die Bereitstellung eines Auskleidungsmaterials, wobei das textile Trägermaterial ein Vliesstoff ist, der aus einer Materialmischung besteht, enthaltend ECR-Glasfasern und Polyolefmfasern im Bereich von 70:30 Gew.-% bis 30:70 Gew.-%, insbesondere im Bereich von 85 Gew.-% ECR-Glasfasern und 15 Gew.-% Polypropylenfasem. Die obigen Aufgaben konnten weiterhin erfmdungsgemäß gelöst werden durch die Bereitstellung eines Auskleidungsmaterials, wobei die Textilschicht eine Vliesstoffschicht ist, die mit Endlosfäden aus ECR-Glasfasern verstärkt ist. Furthermore, it is possible, for example, to apply a foam coating in situ to the textile layer by carrying out a foam coating with a suitable polymer dispersion. This dispersion is preferably loaded with air with a foam mixer. By suitable choice of the process parameters, coatings can be produced from small-cell open-cell foams. The above objects could also be achieved according to the invention by providing a lining material, wherein the textile carrier material is a nonwoven fabric is composed of a material mixture containing ECR glass fibers and polyolefin fibers in the range of 70:30 wt .-% to 30:70 wt .-%, in particular in the range of 85 wt .-% ECR glass fibers and 15 wt. % Polypropylene fibers.

Die Nahtabdeckung kann innen oder außen unterschiedlich ausgeführt sein (Verstärkung, Überlappung, zusätzliches Band, etc.). Die obigen Aufgaben konnten weiterhin erfindungsgemäß gelöst werden durch die Bereitstellung einer Kanal- und/oder Rohrauskleidung, die ein inversiertes Auskleidungsmaterial enthält, umfassend einen Schlauch aus einem gegebenenfalls verstärkten textilen Trägermaterial als Träger, gegebenenfalls eine einseitige Folienbeschichtung, die gut am Träger haftet und gegebenenfalls einen Kalibrierschlauch. Vorzugsweise ist der Schlauch aus einem gegebenenfalls verstärkten textilen Trägermaterial mit einer Beschichtung oder Kaschierung aus Schaumstoff versehen. The above objects could furthermore be achieved according to the invention by providing a lining material, wherein the tube of textile carrier material has seams, in particular laser-welded seams or ultrasonically welded or glued seams, and optionally a seam covering. The seam cover may be different inside or outside (reinforcement, overlap, additional tape, etc.). The above objects could also be achieved according to the invention by providing a channel and / or tubular lining containing an inversed lining material, comprising a tube of an optionally reinforced textile support material as a carrier, optionally a one-sided film coating, which adheres well to the carrier and optionally one calibration hose.

H. without causing a narrowing or widening of the pipe diameter which is outside this tolerance.
Der Schaumstoff dient als Abdichtung und erhöht somit die Dichtigkeit des gesamten Systems. Dies wird durch die feine Verteilung der Poren in einem Schaumstoff erreicht. Im Zusammenwirken der Poren mit der härtbaren Harzzusammensetzung wird verhindert, dass eingeschlossene Luft durch diese Barriere dringen kann. Ohne Verwendung des Schaumstoffes würden durch die aufgrund des Imprägniervorganges immer vorhandene Luft Mikxokanäle erzeugt, welche zu einer Undichtigkeit des Gesamtsystems führen würden. Die Schaumstoffschicht verhindert die Bildung dieser Mikrokanäle bzw. sorgt dafür, dass sie sich sofort wieder schließen. The foam serves as a seal and thus increases the tightness of the entire system. This is achieved by the fine distribution of the pores in a foam. The interaction of the pores with the curable resin composition prevents trapped air from passing through this barrier. Without the use of the foam, the air which is always present due to the impregnation process would produce microchannels which would lead to a leakage of the entire system. The foam layer prevents the formation of these microchannels or ensures that they close again immediately.
