Description

Filterrohr für Rohrbrunnen Die Erfindung betrifft ein Filterrohr für Rohrbrunnen, insbesondere aus Kunststoff, und geht von den bekannten Ausführungen aus, bei denen das Filterrohr in der Außenwand muldenförmige Vertiefungen aufweist, in deren Grund je ein Filterschlitz eingeschnitten ist. Derartige Filterrohre haben den Nachteil, daß sich die Filterschlitze, deren Wandungen parallel zueinander angeordnet sind, leicht durch das Festsetzen von Sand verstopfen.Filter pipe for pipe wells The invention relates to a filter pipe for Pipe wells, especially made of plastic, and goes from the known designs in which the filter tube has trough-shaped depressions in the outer wall, a filter slot is cut into the bottom of each. Have such filter tubes the disadvantage that the filter slots, the walls of which are arranged parallel to one another are easily clogged by the settling of sand.

Man hat deshalb schon Filterrohre mit sich nach innen erweiternden Filterschlitzen hergestellt. Bei diesen Filterrohren sind aber die Filterschlitze in konischer Form in die Rohrwandung eingearbeitet, was herstellungstechnisch erhebliche Schwierigkeiten bereitet.One therefore already has filter pipes with inwardly widening ones Filter slots made. In these filter tubes, however, are the filter slots incorporated into the pipe wall in a conical shape, which is considerable in terms of manufacturing technology Causes difficulties.

Der Erfmdung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen und ein Filterrohr der eingangs angegebenen Art so auszubilden, daß eine Verstopfung der Filterschlitze nicht eintreten kann. Dies wird dadurch erreicht, daß die Rohrwand an den Enden jedes Filterschlitzes mit Quereinschnitten versehen ist, so daß die die Filterschlitze begrenzenden zungenartigen Wandteile durch den Druck des das Filterrohr umgebenden Erdreichs unter elastischer Verformung nach innen gebogen werden und dadurch die Filterschlitze einen zum Rohrinneren sich erweiternden Querschnitt erhalten.The object of the invention is to eliminate these disadvantages and to form a filter tube of the type specified in the opening paragraph so that a blockage the filter slots cannot enter. This is achieved in that the pipe wall is provided with transverse cuts at the ends of each filter slot so that the the filter slots delimiting tongue-like wall parts by the pressure of the Filter pipe surrounding soil bent inwards with elastic deformation and thereby the filter slots have a cross-section that widens towards the inside of the pipe obtain.

Der Vorteil dieser Ausführung liegt darin, daß die Herstellung der Schlitze einfach und billig erfolgen kann, daß sich Sandkörner in den Schlitzen nicht festsetzen können und ein leichter Durchfluß des Wassers erfolgt.The advantage of this design is that the production of the Slots can be done easily and cheaply by placing grains of sand in the slots can not settle and there is a slight flow of water.

In der Zeichnung ist ein Ausführungsbeispiel eines Filterrohres nach der Erfindung dargestellt. Es zeigt Abb. 1 eine Ansicht des Filterrohres, Abb. 2 einen Querschnitt des Filterrohres, Abb.3 einen Ausschnitt des Querschnitts nach Abb. 2 in vergrößertem Maßstab und Abb.4 einen Querschnitt des Filterrohres in der Darstellung gemäß Abb. 3, nachdem es dem Druck des Erdreichs ausgesetzt ist.In the drawing, an embodiment of a filter tube is according to of the invention shown. Fig. 1 shows a view of the filter tube, Fig. 2 a cross section of the filter tube, Fig. 3 a section of the cross section according to Fig. 2 on an enlarged scale and Fig.4 a cross section of the filter tube in the Representation according to Fig. 3 after it has been exposed to the pressure of the earth.

In dem Filterrohr 1 sind die muldenförmigen Vertiefungen 2 angebracht, in deren tiefsten Stellen die Längsschlitze 3 eingeschnitten sind. Von den Längsschlitzen gehen die Quereinschnitte 4 aus.In the filter tube 1, the trough-shaped depressions 2 are made, in the deepest points of which the longitudinal slots 3 are cut. The transverse incisions 4 start from the longitudinal slots.

In der Abb. 4 stellt der mit 5 bezeichnete Winkel die Konizität des Schlitzes dar. Mit 6 ist das Maß angegeben, um welches die zungenartigen Wandteile der Schlitze durch den Erddruck nach innen gedrückt worden sind.In Fig. 4, the angle marked 5 represents the conicity of the Slit. With 6 the amount is indicated by which the tongue-like wall parts of the slots have been pushed inwards by the earth pressure.
