Abstract

The flexible irrigation-pipe can be laid underground at a depth of, for example, one metre, and can be covered in straw, coconut matting and/or plastic fabric. The underneath side of the pipe is preferably continuous, without holes, but the top side of the pipe has slits or holes in. The openings in the top side of the pipe have sealing-rings in, with the result that the water-flow inside the pipe produces a static, pre-set pressure. When this pre-set pressure is exceeded, the water is released up to the soul surface and thereby to the plants, through teh sealing-strips which can also be made of porous material. The water is thereby uniformly distributed along the entire irrigation system, and released in equal quantities from the pipe. The static water pressure guaranteed can be 0.1 atmospheres.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

"Flexible Bewässerungsrohre" Es ist bekannt, trockene Äcker zu bewässern."Flexible irrigation pipes" It is known to irrigate dry fields.

Man benutzt hierzu vielfach Berieselungsanlagen. Jedoch ist die Verdunstunqsrate beim Berieseln von Äckern sehr hoch. Teilweise verdunstet das zugeführte Wasser bis zu 90 %.Sprinkling systems are often used for this purpose. However, the evaporation rate is very high when sprinkling fields. Some of the water supplied evaporates up to 90%.

Hinzu kommt, daß an der Oberfläche eine harte Kruste entsteht, die das Wachstum hindert.In addition, a hard crust arises on the surface, which hinders growth.

Es ist weiterhin bekannt, Entwässerungsrohre unterflur teilweise bis zu 1 m Tiefe zu verlegen, wobei diese Entwässerungsrohre Lochungen aufweisen, die vielfach mit Stroh, Kokos-Flies und/oder Kunststoff-Flies umlagert sind, um ein Zusanden der Zulauf löcher zu vermeiden.It is also known to partially up underfloor drainage pipes to be laid to a depth of 1 m, these drainage pipes have holes that often with straw, coconut fleece and / or plastic fleece are surrounded to a Avoid filling the inlet holes.

Zur Bewässerung wird erfindungsgemäß vorgeschlagen, ähnlich wie bei der Entwässerung flexible Rohre mit Lochungen zu verwenden, wobei jedoch erfindungsgemäß, die Unterseite des Rohres vorzugsweise bis zur Hälfte geschlossen bleibt, d.h. nicht mit Lochungen versehen ist, sondern nur die Oberseite in Richtung Erdoberfläche Bohrungen bzw. Lochungen oder schlitzförmige Öffnungen aufweist.For irrigation is proposed according to the invention, similar to to use flexible pipes with perforations for drainage, but according to the invention the bottom of the tube preferably remains half closed, i.e. not is provided with holes, but only the top towards the surface of the earth Has bores or holes or slot-shaped openings.

Weiterhin wird erfindungsgemäß vorgeschlagen, die Öffnungen mit Dichtringen zu versehen, die eine Garantie geben, daß die Wasserzufuhr im Rohr einen statischen vorgegebenen berechneten Druck erzeugt und erst bei Überhöhung des Druckes durch die Dichtstreifen, die auch porös ausgebildet sein können, das Wasser in Richtung Erdoberfläche freigibt.Furthermore, it is proposed according to the invention, the openings with sealing rings which give a guarantee that the water supply in the pipe is static predetermined calculated pressure generated and only when the pressure is increased by the sealing strips, which can also be made porous, the water in the direction Releases earth's surface.

Durch diese erfindungsgemäße Ausführung ist gewährleistet, daß im gesamten angeschlossenen Bewässerungssystem das Wasser gleichmäßig verteilt und in gleichen Mengen aus dem rohrförmigen Körper austritt.This embodiment of the invention ensures that in throughout the connected irrigation system, the water is evenly distributed and emerges from the tubular body in equal amounts.

In der beiliegenden Zeichnung ist die erfindungsgemäße Bewässerungsrohrausführung dargestellt: Mit 1: die Wasserzufuhr mit 2: Vertiefungen mit Dichtstreifen mit 3: eine andere Art der Vertiefung mit Dichtringen mit 4: Lochungen oder schlitzförmige Öffnungen mit 5: Dichtringe mit 6: der zu bewässernde Boden mit 7: eine Baum- oder Bepflanzungsanordnung mit 8: die dichte, untere Halbschale des BewäLseru?gsrohr-s Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, zur Bewässerung von Bepflanzungsgebieten oder Äckern flexible unterflur-angeordnete Bewässerungsrohre zu verwenden, die erfindungsgemäß Öffnungen in Form von Bohrungen oder Schlitzungen aufweisen, wobei diese Öffnungen mit Dichtringen versehen sind, die erst bei einem bestimmten vorgegebenen und gewünschten Druck sich öffnen und somit erfindungsgemäß mindestens einen statischen Wasserdruck von 0,1 atü garantieren, wobei bei höheren Drücken die Dichtringe sich nur vorzugsweise durch den Innendruck anheben und somit das Wasser frei lassen und bei leichter zu bewässernden Böden, bereits schon im Bereich bei 0,1 atü, die Dichtringe, die porös ausgebildet sind, eine Wasserdiffusion zur Erdoberfläche gerichtet durchlassen und vorzugsweise die untere Halbschale des Bewässerungsrohres geschlossen ist.In the accompanying drawing is the irrigation pipe design according to the invention shown: with 1: the water supply with 2: indentations with sealing strips with 3: Another type of recess with sealing rings with 4: perforations or slot-shaped Openings with 5: sealing rings with 6: the soil to be irrigated with 7: a tree or Planting arrangement with 8: the dense, lower half-shell of the irrigation pipe Of course the invention is not limited to those illustrated and described in detail above Forms of training limited, but numerous changes are possible without however, to deviate from the basic idea of irrigating planted areas or fields to use flexible underfloor arranged irrigation pipes according to the invention Have openings in the form of bores or slots, these openings are provided with sealing rings, which are only given and desired when a certain Pressure open and thus according to the invention at least a static water pressure of 0.1 atm, whereby at higher pressures the sealing rings only preferentially raise by the internal pressure and thus let the water free and with easier to irrigating soils, already in the range at 0.1 atmospheric pressure, the sealing rings, which are porous are designed to let through a water diffusion directed towards the earth's surface and preferably the lower half-shell of the irrigation pipe is closed.
