Abstract

The inner layer of filter material around the slotted land drainpipes is protected by an outersheath of organic textile material which rots away after a given length of burial in the ground. The filter layer proper is of an acrylic material and remains stable after rotting of the sheath.

Description

Filterschicht, insbesondere für ein Drainagerohr Die Zusatzanmeldung betrifft eine Filterschicht, mit mindestens zwei magen, insbesondere für ein Drainagerohr, bei der eine Lange aus einem filternden Material und die andere Lage aus einem organischen Textil besteht, das die Fahigkeit aufweist, sich nach einer ewissen Zeitspanne im Boden aufzulösen, nach Patent (Patentanmeldung F 2n O2 763.4).Filter layer, especially for a drainage pipe The additional application relates to a filter layer, with at least two stomachs, especially for a drainage pipe, one length of a filtering material and the other layer of an organic one Textile is made that has the ability to move in after a long period of time Dissolve soil, according to patent (patent application F 2n O2 763.4).

Der Zusatzerfindung liegt die Aufgabe zugrunde, eine Filterschicht mit mindestens zwei Lagen, insbesondere fiT ein Drainagerohr zu schaffen, mit dem die hydraulische Minderleistung aufgrund der Primäverschlemmung vermieden werden kann und bei der die wasserführende Filterschicht unverrottbar ist. The additional invention is based on the task of a filter layer to create a drainage pipe with at least two layers, in particular fiT, with which the hydraulic underperformance due to the primary obstruction can be avoided can and in which the water-bearing filter layer cannot rot.

In Lösung der gestellten Aufgabe ist eine Filterschicht der vorgenannten Gattung geschaffen worden, die dadurch gekennzeichnet ist, daß das filterende Material aus Acryl beslfi t, dns von einem organischen Textil ummantelt ist. A filter layer of the type mentioned above is the solution to the problem posed Genus has been created, which is characterized in that the filtering material Made of acrylic, which is encased in an organic textile.

Ein Vorteil dieser Ausbildung besteht darin, daß sich das organische Textil nach einer gewissen Zeit iln Boden rückstandsfrei auflöst und,nach dem sich ein stabiles Bodengefüge wieder gebildet hat, ein unverrottbares Filtermaterial um das wasserführende Schlitzrohr 0. An advantage of this training is that the organic Textile dissolves in the floor without residue after a certain period of time and, after that has re-established a stable soil structure, a rot-proof filter material around the water-bearing slotted pipe 0.

Ein Ausführungsbeispiel der Erfindung, aus dem sich weitere erfinderische Merkmale ergeben, ist in der Zeichnung dargestellt. An embodiment of the invention from which further inventive Characteristics result is shown in the drawing.

Die Abbildung zeipft ein Drainagerohr '1', das aus einem wasserführenden Schlitzrohr 4', einem um dieses Schlitzrohr angeordneten Acrylfilter 3' und einer Außenumhüllung aus einem organischen Textil 2' besteht. The figure shows a drainage pipe '1' that comes from a water-bearing Slotted tube 4 ', an acrylic filter 3' arranged around this slotted tube and one The outer covering consists of an organic textile 2 '.
