Abstract

A plant or lawn watering pipe of hosepipe, produced pref. from plastic material such as poly vinyl chloride, is constructed such that the wall of the pipe or tube has a series of slits cut into it which run in the longitudinal direction of the hose pipe and are arranged in groups around the pipe periphery. The slits remain closed under low water pressures but open to allow out flow of water for watering purposes as the water pressure within the hose rises.

Bewas serungsrohrIrrigation pipe

Die Erfindung betrifft ein Rohr bzw. eine Rohrleitung zur künstlichen Bewässerung des Erdbodens zwecks Versorgung von Pflanzen aller Art mit Wasser.The invention relates to a pipe or a pipeline for artificial irrigation of the ground for the purpose Supply of all kinds of plants with water.

Die künstliche Bewässerung eines Pflanzen tragenden Erdbodens erfolgt im allgemeinen durch Zuleitung von Wasser in offenen Gräben, oder durch Verspritzen von Wasser in die Luft, wobei die Erde von der Ackeroberfläche her benäßt wird. Bei warmem Wetter ist hierbei die Verdunstung von Wasser sehr erheblich,The artificial irrigation of a soil bearing plants is generally carried out by supply lines of water in open trenches, or by splashing water into the air, removing the earth from the field surface is wetted here. In warm weather, the evaporation of water is very significant,

V7odurch ein großer Verlust an Wasser entsteht. Dieses Bewässerungsverfahren kann daher bei heißem Klima oder bei Wassermangel meistens nicht angewendet werden. V7o results in a great loss of water. This Irrigation methods can therefore be used in hot climates or are usually not used in the event of a lack of water.

Wenn man das Wasser unter der Erdoberfläche etwa in der Wurzeltiefe der Pflanzen zuleiten würde, könnte der Wasserbedarf allerdings ganz erheblich herabgesetzt v/erden. Eine solche unterirdische Bewässerung hat man mit Hilfe von perforierten Rohren versucht. Die Ausströmung des Wassers aus solchen perforierten Rohren erfolgt aber in direktem Verhältnis zu der Länge der Rohrleitungen, wodurch die Anwendung dieses Bewässerungsverfahrens begrenzt wird. Außerdem können sich die offenen Perforationslöcher sehr leicht verstopfen.When you get the water below the surface of the earth If it were to be fed into the roots of the plants, the water requirement could, however, be quite considerable reduced to earth. Such underground irrigation is done with the help of perforated pipes tries. However, the outflow of water from such perforated pipes is in direct proportion to the length of the pipelines, thereby limiting the use of this irrigation method. In addition, the open perforation holes can become clogged very easily.

Der Erfindung liegt die Aufgabe zugrunde, die Bewässerungsrohre zur künstlichen Bewässerung von Erdreich so zu verbessern, daß sie ein gleichmäßigeres Ausströmen des Wassers ermöglichen.The invention is based on the object, the irrigation pipes for artificial irrigation of the ground to improve so that they allow a more even outflow of the water.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst s daß die Wandung des Rohres mit in gegenseitigen Abständen angeordneten, ira wesentlichen in LängsrichtungThis object is inventively achieved in s that the wall of the tube which is arranged in mutual distances, ira substantially longitudinally

des Rohres verlaufenden Einschnitten versehen ist, Vielehe bei niedrigem Innendruck geschlossen sind, bei steigendern Innendruck dagegen unter der Wirkung dieses höheren Druckes selbsttätig geöffnet werden und das Wasser in die Umgebung des Rohres ausströmen lassen. Die Einschnitte gehen natürlich durch die ganze Wandstärke des Rohres hindurch. Sie können sowohl in Längsabständen als auch in Umfangs-Abständen angeordnet sein.incisions running through the pipe, polygons are closed at low internal pressure, with increasing internal pressure, however, are automatically opened under the effect of this higher pressure and let the water flow out into the vicinity of the pipe. The cuts go through, of course through the entire wall thickness of the pipe. You can use both lengthways and circumferential distances be arranged.

Durch entsprechend der Rohrlänge gewählte Bemessung des Rohrquerschnittes arbeitet ein solches Bewässerungsrohr bei niedrigem Innendruck lediglich als Wasserleitung zur Förderung von Wasser, weil über die ganze Rohrlänge fast der gleiche Druck im Inneren des Rohres herrscht. Wenn dagegen der Wasserdruck in dem Rohr erhöht wird, öffnen sich die Einschnitte der Rohrwandung selbsttätig unter der Wirkung des erhöhten Innendruckes. Wenn weiterhin ein geeignetes Verhältnis zwischen dem Rohrquerschnitt und der Rohrlänge eingehalten wird, ist die Druckzunahme in dem gesamten Rohr beinahe die gleiche, d.h., es ist kein großer Unterschied zwischen dem Ausströmen des Wassers an den verschiedenen Stellen und an den verschiedenen Enden des Rohres vorhanden.Such an irrigation pipe works by dimensioning the pipe cross-section according to the pipe length at low internal pressure only as a water pipe for pumping water, because over the The pressure inside the pipe is almost the same for the entire length of the pipe. If, on the other hand, the water pressure in the Pipe is increased, the incisions in the pipe wall open automatically under the effect of the increased Internal pressure. If still a suitable ratio between the pipe cross-section and the pipe length is observed, the pressure increase is almost the same throughout the pipe, i.e. there is not much difference between the outflow of water at the different points and at the different ends of the pipe available.
