Abstract

In the two-layer filter coating partic. for a land drainage pipe, as disclosed in parent patent, in which one layer consists of a filtering material and the othe ris an organic textile, having the capability to dissolve in the soil after a certain time, the improvement whereby the filtering material consists of coconut fibre and is enclosed in a layer of organic material, e.g. straw.

Description

Filterschicht, insbesondere für ein Drainagerohr Die Zusatzanmeldung betrifft eine Filterschicht mit mindestens zwei Lagen, insbesondere für ein Drainage rohr, bei der eine Lage aus einem filternden Material und die andere Lage aus einem organischen Textil besteht, das die Fähigkeit aufweist, sich nach einer gewissen Zeitspanne im Boden aufzulösen, nach Patent (Patentanmeldung P 21 02 763.4).Filter layer, especially for a drainage pipe The additional application relates to a filter layer with at least two layers, in particular for drainage tube, one layer of a filtering material and the other layer of a organic textile is made, which has the ability to look after a certain Dissolve time span in the ground, according to patent (patent application P 21 02 763.4).

Der Zusatzerfindung liegt die Aufgabe zugrunde, eine Filterschicht mit mindestens zwei Lagen, insbesondere für ein Drainagerohr zu schaffen, mit dem hydraulische Minderleistung aufgrund der Primärverschlemmung vermieden werden kann und bei der die wasserführende Filterschicht verhältnismäßig resistent gegen die Bodeneinflüsse ist. The additional invention is based on the task of a filter layer to create with at least two layers, especially for a drainage pipe, with the hydraulic underperformance due to the primary silting can be avoided and in which the water-bearing filter layer is relatively resistant to the Soil influences is.

In Lösung der gestellten Aufgabe ist eine Filterschicht der vorgenannten Gattung geschaffen worden, die dadurch gekennzeichnet ist, daß das filternde Material aus Kokosfasern besteht, das von einem organischen Material, z. B. Stroh, 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 consists of coconut fiber, which is made of an organic material, z. B. straw, is coated.

Ein Vorteil dieser Ausbildung besteht darin, daß sich das organische Material der Ummantelung nach einer gewissen Zeit im Boden rückstandsfrei auflöst und, nach dem sich ein stabiles Bodengefüge wieder gebildet hat, ein nahezu unverrottbares Filtermaterial um das wasserführende Schlitzrohr o. dgl. verbleibt. An advantage of this training is that the organic The material of the casing dissolves in the soil without leaving any residue after a certain period of time and, after a stable soil structure has formed again, an almost rot-proof one Filter material around the water-bearing slotted pipe or the like. Remains.

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 zeigt ein Drainagerohr la, das aus einem wasserführenden Schlitzrohr 4a, einem um dieses Schlitzrohr angeordneten Kokosfilter 3a und einer Außenumhüllung aus einem organischen Material 2a, z. B. The figure shows a drainage pipe la, which consists of a water-bearing Slotted tube 4a, a coconut filter 3a arranged around this slotted tube and one Outer envelope made of an organic material 2a, e.g. B.

Stroh, besteht.Straw, consists.
