Description

Durch äußere Kräfte, z. B. Erddruck, beanspruchter Rohrleitungsabschnitt aus mehreren Kunststoff-Muffenrohren Die Erfindung betrifft einen durch äußere Kräfte, z. B. Erddruck, beanspruchten Rohrleitungsabschnitt aus mehreren Kunststoff-Muffenrohren, bei dem das Spitzende jedes Rohres bis zum Grunde in den Muffenteil des benachbarten Rohres eingeschoben ist. Bei Verwendung von Rohren mit normalen Muffen sind für derartige Leitungsabschnitte besondere Rohre mit größerer Wandstärke erforderlich.By external forces, e.g. B. earth pressure, stressed pipe section from several plastic socket pipes The invention relates to a by external forces, z. B. earth pressure, stressed pipe section made of several plastic socket pipes, in which the spigot end of each pipe goes down to the bottom in the socket part of the neighboring one Tube is inserted. When using pipes with normal sleeves are for such pipe sections require special pipes with greater wall thickness.

Aufgabe der Erfindung ist es, einen solchen durch äußere Kräfte beanspruchten Rohrleitungsabschnitt aus Kunststoff-Muffenrohren derart auszubilden, daß in diesem Abschnitt keine Muffenrohre mit größerer Wandstärke verwendet werden müssen. Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die innere Tiefe des Muffenteiles aller Rohre des Rohrleitungsabschnittes 40 bis 50 % der Rohrlänge beträgt. Der günstigste Fall ist der, daß die innere Muffentiefe gleich der halben Rohrlänge ist.The object of the invention is to design such a pipe section made of plastic socket pipes, which is stressed by external forces, in such a way that socket pipes with a greater wall thickness do not have to be used in this section. According to the invention, this object is achieved in that the inner depth of the socket part of all pipes of the pipe section is 40 to 50 % of the pipe length. The most favorable case is that the inner socket depth is equal to half the pipe length.

Zur Erleichterung des Einbaus und zur Ermöglichung des nachträglichen Einsetzens von Anschlußstücken sowie des Austausches von Rohrstücken ist es bekannt, Langmuffen zu verwenden, deren Länge etwa gleich der Hälfte der Rohrlänge ist. Bei dieser bekannten Verwendung von Langmuffenrohren ist aber eine Erhöhung der Außendruckfestigkeit weder beabsichtigt noch erforderlich. Dagegen wird beim Anmeldungsgegenstand durch die beim Einstecken des Innenrohres verdoppelte Wandstärke eine sehr stark erhöhte Steifigkeit erreicht ohne daß hierfür Rohre mit dickerer Wand erforderlich wären.To facilitate installation and to enable subsequent Insertion of connecting pieces and the exchange of pipe pieces, it is known Use long sleeves, the length of which is approximately equal to half the pipe length. at However, this known use of long socket pipes is an increase in the external pressure resistance neither intended nor required. On the other hand, the subject of the application is through the wall thickness doubled when the inner tube was inserted, a very large increase Rigidity achieved without the need for pipes with thicker walls.

In der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemäßen Rohrleitungsabschnittes dargestellt.In the drawing is an embodiment of an inventive Pipe section shown.

Der dargestellte Rohrleitungsabschnitt besteht aus Kunststoff-Langmuffenrohren, die einen Muffenteil 2, einen übergangsteil 3 und ein Spitzende 4 aufweisen. Im Muffenteil 2 ist eine rechteckige Nut 1 zur Aufnahme eines Dichtungsringes vorgesehen. Der Innendurchmesser der Muffe ist nahezu gleich dem Außendurchmesser des Spitzendes 4, um bei Außenbelastung eine gute Kraftübertragung zu erhalten. Die Spitzenden 4 der Muffenrohre sind bis zum Grunde in die Muffenteile der jeweils benachbarten Rohre eingeschoben. Die innere Tiefe t des Muffenteiles 2 beträgt etwa 50 1/o der Rohrlänge L.The pipeline section shown consists of plastic long socket pipes which have a socket part 2, a transition part 3 and a spigot end 4. In the socket part 2, a rectangular groove 1 is provided for receiving a sealing ring. The inside diameter of the sleeve is almost the same as the outside diameter of the spigot end 4, in order to obtain good power transmission in the case of external loads. The spigot ends 4 of the socket pipes are pushed right down to the bottom into the socket parts of the respective adjacent pipes. The inner depth t of the socket part 2 is about 50 1 / o of the pipe length L.
