Die Erfindung beschreibt als Produkt einen Filterrohr mit kleinem Durchmesser für den Einsatz als Pegelfilter.The Invention describes as a product a filter tube with a small diameter for the Use as level filter.
Die Verwendung von Filterrohren als Pegelfilter im Bereich der Grundwasserkontrolle ist aus dem Stand der Technik bekannt. In allen Tagebauen in denen Wasserhaltung notwendig ist, da der Abbau der Rohstoffe sich unterhalb des Grundwasserspiegels abspielt, werden derartige Pegelfilter verwendet um den Grundwasserspiegel zu kontrollieren.The Use of filter tubes as level filters in the field of groundwater control is known from the prior art. In all opencast mines in those Dewatering is necessary as the degradation of the raw materials is below the groundwater level, such level filters are used to to control the groundwater level.
Zur Kontrolle des Grundwasserspiegels werden üblicherweise Bohrungen im Tagebau selber aber auch in dem umliegenden Gelände abgeteuft, und in diese Bohrungen die sogenannten Pegelfilter eingebracht.to Control of the groundwater level are usually wells in open pit but also sunk in the surrounding area, and in this Holes introduced the so-called level filter.
Dabei handelt es sich um gelochte Stahlrohre die zum Schutz vor Versandung mit einem mineralischem Filtermaterial umgeben sind. Dieses verhindert das Eindringen von Sand oder Gestein durch die Bohrungen in das Filterrohr, wodurch es zu einer Versandung bzw. Verstopfung desselben kommen würde.there These are perforated steel tubes that protect against silting surrounded by a mineral filter material. This prevents the penetration of sand or rock through the holes in the Filter tube, whereby it to a silting or blockage of the same would come.
Diese als Pegelfilter bezeichneten Filterrohre werden über eine Rohrstrecke miteinander verschraubter Rohrlängen mit der Erdoberfläche verbunden. Typischerweise besteht der Filterbelag aus einem Mineralgemisch, welches durch einen speziellen Kelbstoff dauerhaft miteinander verbunden ist. Diese typischerweise als Kiesklebefilter bezeichneten Filterrohre weisen Bauart bedingt einen größeren Durchmesser auf, als die an die Erdoberfläche führenden Rohre. In der Betrachtung der Gesamtrohrstrecke ergibt sich somit eine Verdickung bedingt durch diese Bauart der Pegelfilter. In G 86 20 201 U1 ist dieser Pegelfilter ausführlich beschrieben.These Filter tubes designated as level filters are interconnected via a pipe run screwed tube lengths with the earth's surface connected. Typically, the filter pad consists of a mineral mixture, which is permanently connected by a special Kelbstoff is. These typically referred to as Kiesklebefilter filter tubes wise design requires a larger diameter on, as the to the earth's surface leading Tube. In the consideration of the total pipe length thus results a thickening due to this type of level filter. In G 86 20 201 U1, this level filter is described in detail.
Da beim Abteufen der Bohrungen es geschehen kann, dass mehrmals Wasser undurchlässige Schichten durchbohrt werden, müssen nachträglich für jede der Wasser führenden Schichten Pegelfilter in das Bohrloch eingebracht werden. Diese werden von unten nach oben nacheinander in ein dasselbe Bohrloch eingebaut. Auf Höhe der Wasser undurchlässigen Schicht wird das Bohrloch verschlossen, und dann der nächste Pegelfilter für die darüber liegende Schicht eingebaut. So müssen bis zu 5 und mehr Pegelfilter in ein und dasselbe Bohrloch eingebracht werden.There When drilling the holes it can happen that several times water impermeable layers must be pierced retrospectively for each of the Water leading Layers of level filter are introduced into the borehole. These become successively from bottom to top in a same borehole built-in. At height the water impermeable Layer is closed the well, and then the next level filter for the about that installed layer. So have to up to 5 or more level filters placed in one and the same hole become.
Hierbei stellt sich das Problem, dass die Pegelfilter die mit einer Kiesklebeschicht versehen sind einen zu großen Durchmesser aufweisen um alle Pegelfilter in einem Bohrloch unterzubringen. Und schon bei nur 3 Pegelfiltern zeigt es sich oftmals, dass der gegenüber den Verbindungsrohren größere Durchmesser der Pegelfilter den Einbau behindern kann und hierdurch einen Zeitverzug und somit höhere Kosten verursacht.in this connection poses the problem that the level filters with a gravel layer provided are too big Have diameter to accommodate all level filters in a wellbore. And even with only 3 level filters, it often shows that the across from the connecting pipes larger diameter the level filter can hinder the installation and thereby a time delay and thus higher Costs caused.
Wesentlich nachteiliger, weil deutlich teurer ist jedoch die zusätzliche Bohrung die abgeteuft werden muß, um die restlichen Pegelfilter einbauen zu können.Essential disadvantageous, because significantly more expensive, however, is the additional Hole that needs to be sunk to install the remaining level filters.
Die Aufgabe besteht nunmehr darin einen Pegelfilter zu erfinden, dessen äußerer Durchmesser kleiner oder allenfalls gleich groß als der größte Durchmesser der Verbindungsrohre ist ohne das dabei das Ansprechverhalten des Filters aufgrund der kleineren Filteroberfläche verschlechtert wird. Dieser wird typischerweise durch den äußeren Durchmesser der Verbindungsmuffe definiert, welche die Verbindungsrohre miteinander verbindet.The Task is now to invent a level filter whose outer diameter smaller or at most the same size as the largest diameter the connecting tubes is without the response of the Filter is deteriorated due to the smaller filter surface. This one will typically by the outer diameter the connecting sleeve defines which the connecting tubes with each other combines.
Diese Aufgabe wird dadurch gelöst werden, dass die vergleichsweise dicke Kiesklebeschicht durch ein anderes Filtermedium substituiert wird. Als ein geeignetes Filtermedium hierfür kann zum Beispiel ein Drahtgewebe oder besser ein mehrlagiges Drahtgewebe genutzt werden. Eine Ausführungsvarainte dieses Drahtgewebelaminates ist in 103 57 693.2 offenbart.These Task is solved be that the comparatively thick gravel layer by a other filter medium is substituted. As a suitable filter medium therefor For example, a wire mesh or, more preferably, a multi-ply wire mesh be used. An execution variety this wire mesh laminate is disclosed in 103 57 693.2.
Mit dieser Erfindung wird erreicht, dass nun nicht mehr der Durchmesser des Pegelfilters das begrenzende Element beim Einbau in das Bohrloch darstellt. Somit ist es möglich mehr Pegelfilter als bisher in das Bohrloch einzubringen. Die Abteufung eines weiteren Bohrloches wird dadurch vermieden, was mit großen Kosteneinsparungen verbunden ist. Die im Vergleich zu dem Kiesklebefilter große freie Filterfläche gestattet es auch, den Durchmesser der Verbindungsrohre der typischerweise 60,3 mm beträgt, noch weiter zu verkleinern, was sowohl Materialkosten als auch Montagekosten einspart. Dies wird durch das sehr schnelle Ansprechverhalten des Pegelfilters unterstützt.With This invention is achieved that now no longer the diameter the level filter the limiting element when installing in the borehole represents. Thus it is possible to introduce more level filters than before into the borehole. The reduction Another borehole is thereby avoided, resulting in great cost savings connected is. The large compared to the gravel adhesive large filter area also allows the diameter of the connecting pipes of the typically 60.3 mm, still to further reduce what both material costs and assembly costs saves. This is due to the very fast response of the Level filters supported.

Auf diese Weise wird sichergestellt, dass der Außendurchmesser des Pegelfilterrohres kleiner als der Muffendurchmesser ist und trotzdem eins große frei Filterfläche zur Verfügung steht die ein schnelles Ansprechverhalten des Pegelfilters gewährleistet.On This way, it ensures that the outside diameter of the level filter tube smaller than the sleeve diameter and still one big free filter area to disposal stands the fast response of the level filter guaranteed.
