Abstract
Description
Die Erfindung betrifft eine Hinterfüllmatte, insbesondere für den untertägigen Berg- und Tunnelbau, die im wesentlichen aus einer abdichtenden Mattenschicht, beispielsweise aus Geotextil, wie Vlies, Gewebe oder Verbundstoff und einem verzugartigen Stützgitter besteht.The invention relates to a backfill mat, in particular for underground mining and tunneling, which essentially consists of a sealing mat layer, for example of geotextile, such as fleece, fabric or composite and a warp-like support grid.
Im untertägigen Bergbau ist es bekannt, wie unter anderem in der Zeitschrift "Unser Betrieb", Werkzeitschrift für die Unternehmen der Deilmann-Haniel-Gruppe, Nr. 60, April 1992, Seite 5 beschrieben, in Verbindung mit herkömmlichen Drahtverzugmatten bei Ausbau- und Sanierungsarbeiten eine abdichtende Schicht aus Vlies einzusetzen.In underground mining, it is known, as described, among other things, in the magazine "Unser Betrieb", works magazine for the companies of the Deilmann-Haniel Group, No. 60, April 1992, page 5, in connection with conventional wire warping mats during expansion and renovation work use a sealing layer of fleece.
Diese sogenannte Geotextilschicht aus einem mechanisch oder thermisch verfestigten Textilverbundstoff soll eine Abdichtung bei der Hinterfüllung während der Abbindezeit bewirken bzw. ein Durchtreten der hinterfüllten Betonmassen durch den Verzug in die Strecke verhindern.This so-called geotextile layer made of a mechanically or thermally reinforced textile composite material is intended to seal the backfill during the setting time or to prevent the backfilled concrete mass from passing through the warping in the route.
Die Verwendung von Vlies für derartige Zwecke hat den Vorteil, daß bedingt durch die vorgegebene Struktur des Materials das Überschußwasser, beispielsweise einer Betonmischung durch die abdichtende Schicht austreten kann, jedoch der für die Festigkeit der Hinterfüllung wichtige Zementleim in der Hinterfüllmasse verbleibt. Da dem Geotextil die entsprechende Stützkraft fehlt, wird die notwendige Stützkraft durch den herkömmlichen Drahtverzug gebildet.The use of fleece for such purposes has the advantage that, due to the given structure of the material, the excess water, for example a concrete mixture, can escape through the sealing layer, but the cement paste that is important for the strength of the backfill remains in the backfill. Since the geotextile lacks the corresponding supporting force, the necessary supporting force is formed by the conventional wire warping.
In dieser Kombination von Geotextil und Drahtverzugmatte sind jedoch verschiedene Nachteile enthalten, die eine praktische Anwendung nicht in dem gewünschten Maße zum Tragen kommen lassen.In this combination of geotextile and wire warp mat, however, there are various disadvantages which do not allow practical application to the desired extent.
Drahtverzugmatten sind insbesondere im Untertagebergbau und den dort herrschenden aggressiven und feuchten Wetterverhältnissen empfindlich gegen Korrosion und benötigen daher eine zusätzliche Behandlung, wie Beschichtung oder Verzinkung, wodurch das Produkt äußerst kostenintensiv ist.Wire warping mats are particularly sensitive to corrosion in underground mining and the aggressive and humid weather conditions there, and therefore require additional treatment, such as coating or galvanizing, which makes the product extremely cost-intensive.
Desweiteren sind Drahtverzugmatten, deren Längs- und Querdrähte üblicherweise einen Durchmesser von 6-8 mm aufweisen, aufgrund der vorgegebenen Flächeneinheiten sehr schwer und schwierig zu transportieren. Darüber hinaus sind die Drahtverzugmatten in der Handhabung gefährlich und aufgrund von herstellungsbedingten Kanten, Spitzen und Oberflächenaufrauhungen können Beschädigungen des empfindlichen Geotextils nicht ausgeschlossen werden, wodurch die Dichtigkeit des Geotextils nicht in dem gewünschten Maße gewährleistet werden kann.Furthermore, wire warp mats, whose longitudinal and transverse wires usually have a diameter of 6-8 mm, are very difficult and difficult to transport due to the given surface units. In addition, the wire warp mats are dangerous to handle and, due to manufacturing-related edges, tips and surface roughening, damage to the sensitive geotextile cannot be excluded, which means that the tightness of the geotextile cannot be guaranteed to the desired extent.
Darüber hinaus stellt der Einbau des in sich nicht stabilen und wenig reißfesten Geotextils in Verbindung mit der abstützenden Drahtverzugmatte ein ständiges und nicht zu unterschätzendes Handhabungsproblem dar.In addition, the installation of the geotextile, which is inherently unstable and not very tearproof, in connection with the supporting wire warping mat represents a constant and not to be underestimated handling problem.
Nach der DE-OS 27 07 683 ist unter anderem eine als Kunststoffwasserseige bezeichnete Auskleidung für eine im Berg- und Tunnelbau üblicherweise in der Streckensohle angeordnete Wasserseige beschrieben. Das zur Abdichtung gegen Wasserdurchlässigkeit benötigte Material besteht aus einem Drahtnetz, dessen sich überkreuzende Längs- und Querdrähte miteinander verschweißt sind, wobei eine wasserundurchlässige Folie auf der einen Seite des Drahtgeflechts angeordnet ist, und auf der anderen Seite des Drahtgeflechts zur Befestigung der Folie in den Maschen des Drahtnetzes eine weitere Beschichtung vorgesehen ist.According to DE-OS 27 07 683, a liner called plastic water seige is described for a water seige usually arranged in the bottom of the route in mining and tunnel construction. The material required for sealing against water permeability consists of a wire mesh, the crossing longitudinal and transverse wires are welded to one another, with a water-impermeable foil being arranged on one side of the wire mesh and on the other side of the wire mesh for fastening the foil in the mesh a further coating of the wire mesh is provided.
Der Nachteil von derartig miteinander kombinierten Materialien, die für die Hinterfüllung des Streckenausbaus nicht zu verwenden sind, ist vornehmlich darin zu sehen, daß die Haltbarkeit und Tragfähigkeit des Materials durch Korrosion des Drahtnetzes stark gefährdet ist, und daß zur Befestigung der Folie mit dem Drahtnetz in aufwendiger Herstellung eine zusätzliche Schicht erforderlich ist.The disadvantage of such combined materials, which are not to be used for the backfill of the track extension, is primarily to be seen in the fact that the durability and load-bearing capacity of the material is severely endangered by corrosion of the wire mesh, and that for fastening the foil to the wire mesh in complex production requires an additional layer.
Des weiteren ist nach der DE-OS 41 38 506 eine Verzugmatte bekannt, deren gitterartig nach Art von Kett-und Schußfäden verlaufende Streifen aus Hochleistungstextilgewebe bestehen, wobei die Streifen an den Kreuzungsstellen verschiebefest miteinander verbunden, beispielsweise verwebt sind.Furthermore, according to DE-OS 41 38 506, a drafting mat is known, the strips of which are made of high-performance textile fabric and run in the manner of warp and weft threads, the strips being connected to one another in a manner fixed against displacement, for example woven, at the intersection points.
Eine Verzugmatte wird zur Vermeidung von Steinfall oder in Verbindung mit Beton als Bewehrung eingesetzt. Die Verbindung einer solchen Textilverzugmatte mit einer Folie löst nicht ohne weiteres die bei der Hinterfüllung anstehenden Probleme.A warping mat is used to prevent stone falling or in connection with concrete as reinforcement. The Connecting such a textile warp mat with a film does not easily solve the problems involved in backfilling.
Dem gegenüber liegt der Erfindung die Aufgabe zugrunde, eine Hinterfüllmatte, insbesondere für den Ausbau- und für Sanierungsarbeiten des Berg- und Tunnelbaus zu schaffen, welche die genannten Nachteile vermeidet, die zwischen den Ausbauprofilen eine ausreichende Stützlast gewährleistend ein geringes Gewicht aufweist und in Abhängigkeit des Gewichts in jeder zu verarbeitenden Größe so auch als Rollmatte herstellbar und einsetzbar ist, die eine einfache, sichere und verletzungsfreie Handhabung erlaubt und die kostengünstig und wirtschaftlich herstellbar ist.In contrast, the invention has for its object to provide a backfill mat, in particular for the expansion and renovation work of mining and tunneling, which avoids the disadvantages mentioned, which ensures a sufficient vertical load between the expansion profiles and has a low weight and depending on the Weight in every size to be processed can also be manufactured and used as a rolling mat, which allows simple, safe and injury-free handling and which is inexpensive and economical to manufacture.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Stützgitter als nach Art von Kett- und Schußfäden verlaufende, verschiebefest miteinander verbundene Streifen aufweisendes Hochleistungstextilgittergewebe und in Verbindung mit einer abdichtenden Mattenschicht als Verbundmatte ausgebildet ist.This object is achieved in that the support grid is designed as a high-performance textile grid fabric running in the manner of warp and weft threads, with strips connected to one another in a displaceable manner, and in connection with a sealing mat layer as a composite mat.
Eine derartige Verbundmatte kann in beliebiger Form gefaltet oder gerollt transportiert werden, wobei die Form der Verbundmatte auch vom Einbauverfahren abhängig zu machen ist.Such a composite mat can be folded or rolled in any shape, the shape of the composite mat is also dependent on the installation process.
Die Größe des Gitters oder der Maschenweite bzw. die Stärke der Ausbildung der Kett- und Schußfäden ist in Abhängigkeit von der speziellen Aufgabe variierbar.The size of the grid or the mesh size or the strength of the formation of the warp and weft threads can be varied depending on the specific task.
Der Verbund von Stützgitter und abdichtender Mattenschicht, der durch mindestens punktförmige Verbindungen über die Fläche beider Produkte gewährleistet ist, erlaubt den Vorteil, daß durch den Einbau eines einzigen Produktes erhebliche Arbeitszeit vor Ort eingespart werden kann.The combination of support grid and sealing mat layer, which is ensured by at least point connections over the surface of both products, allows the advantage that by installing a single Product can save considerable working hours on site.
Je nach Wunsch und Aufgabe kann die als Verbundmatte vorgesehene Hinterfüllmatte so ausgebildet sein, daß beispielsweise die abdichtende Mattenschicht gebirgs- und/oder streckenseitig des Stützgitters angeordnet ist. Bei gebirgsseitiger Anordnung des Stützgitters kann dieses zumindestens teilweise als Bewehrung in die Hinterfüllmasse integriert werden. Eine besondere Ausführung der Verbundmatte sieht dabei eine wellenförmige Ausbildung des Stützgitters vor, welches eine intensivere Integration innerhalb der Hinterfüllmasse erlaubt.Depending on the request and the task, the backfill mat provided as a composite mat can be designed such that, for example, the sealing mat layer is arranged on the mountain and / or track side of the support grid. If the support grid is arranged on the mountain side, it can be at least partially integrated into the backfill mass as reinforcement. A special design of the composite mat provides for a wavy design of the support grid, which allows more intensive integration within the backfill.
Bei Bedarf ist jedoch eine zweiseitige Verbindung des Stützgitters mit jeweils einer abdichtenden Mattenschicht vorstellbar, bei der das Stützgitter von beiden Seiten mit jeweils einer abdichtenden Mattenschicht vollständig umgeben ist.If necessary, however, a two-sided connection of the support grid with a sealing mat layer is conceivable, in which the support grid is completely surrounded on both sides with a sealing mat layer.
Bei einer streckenseitigen Anordnung des Stützgitters auf der abdichtenden Mattenschicht ergibt sich für das Stützgitter eine reine Stützfunktion, die aufgrund einer unverrottbaren Ausführung eine erhöhte Sicherheit bei Brüchen und Abbröckeln der Hinterfüllschicht gewährleistet.If the support grid is arranged on the track side on the sealing mat layer, the support grid has a purely support function which, because of the rot-free design, ensures increased safety in the event of breaks and crumbling of the backfill layer.
Herstellungstechnisch ist es möglich, das Stützgitter in die abdichtende Mattenschicht direkt, beispielsweise durch Einweben zu integrieren. Für eine solche Ausführung würde sich ein Vlies-Faden-Nähgewirke besonders eignen.In terms of production technology, it is possible to integrate the support grid directly into the sealing mat layer, for example by weaving in. A fleece thread knitted fabric would be particularly suitable for such an embodiment.
Bei der Verwendung der Hinterfüllmatte, vornehmlich im Berg- und Tunnelbau ist es als zweckmäßig anzusehen, das Stützgitter und die abdichtende Mattenschicht antistatisch, beispielsweise durch Integrieren von metallischen Kurzfasern in die Mattenschicht und gleichzeitig alkalibeständig, beispielsweise durch Imprägnieren auszubilden.When using the backfill mat, primarily in mining and tunneling, it is considered appropriate to use the support grille and the sealing mat layer antistatic, for example by integrating metallic short fibers into the mat layer and at the same time alkali-resistant, for example by impregnation.
Bei Ausführungen der Hinterfüllmatte als Rollmatte erweist es sich als vorteilhaft, die parallel zur Rollachse liegenden Streifen des Stützgitters verstärkt auszubilden, ohne daß der Effekt des Rollens darunter leidet.When the backfill mat is designed as a roll mat, it proves to be advantageous to make the strips of the support grid parallel to the roll axis stronger without the effect of the roll suffering.
Ebenso ist es möglich, im anderen Falle die Querstreifen zu verstärken, um eine Verbundmatte zu erhalten, die eine besondere, den Einbau erleichternde Steifigkeit aufweist.It is also possible, in the other case, to reinforce the transverse strips in order to obtain a composite mat which has a particular rigidity which facilitates installation.
Die Verstärkungen können als metallische Drähte oder vergleichbare Einlagen aus beispielsweise Textilglas, Glasseide oder Filamenten ausgebildet sein.The reinforcements can be designed as metallic wires or comparable inlays made of, for example, textile glass, glass silk or filaments.
Darüber hinaus können bei Bedarf die Verbundmatten streckenseitig durch in Längsrichtung miteinander verbindbare Verzugstäbe unterstützt werden.In addition, if required, the composite mats can be supported on the track side by means of tension rods that can be connected to one another in the longitudinal direction.
Weiterhin ist es im Rahmen der Erfindung vorstellbar, daß die mindestens einseitig mit dem Stützgitter verbundene, abdichtende Mattenschicht mehrschichtig als eine Kombination von miteinander durch beispielsweise Kaschieren, Laminieren oder Versteppen verbundene Schichten ausgebildet ist.Furthermore, it is conceivable within the scope of the invention that the sealing mat layer, which is connected at least on one side to the supporting grid, is constructed in multiple layers as a combination of layers connected to one another by, for example, lamination, laminating or quilting.
Ein Ausführungsbeispiel der erfindungsgemäßen Hinterfüllmatte ist in schematisierter Form in einer Zeichnung dargestellt und wird im nachfolgenden näher erläutert.An embodiment of the backfill mat according to the invention is shown in a schematic form in a drawing and is explained in more detail below.
