Description

Vorrichtung zum Anzeigen und Feststellen schadhafter Stellen an den in der Erde verlegten Gasleitungen Es ist bekannt, über den in der Erde verlegten Gasleitungen Sammelleitungen für etwa ausströmende Gasmengen zu verlegen und diese Sammelleitungen an über dein Erdboden angeordneten Anzeigevorrichtungen anzuschließen. Die Erfindung betrifft eine Verbesserung dieser Sicherheitsvorrichtungen, welche die Feststellung der Lage der schadhaften Stelle erleichtert. Nach der Erfindung sind die Gasleitungen und die Sammelleitungen von einer gasdurchlässigen Schicht umgeben, die in an sich bekannter Weise an einzelnen Stellen durch eine undurchlässige Sperrschicht unterteilt ist, und es sind an den gleichen Stellen in dem Sammelrohr von der Erdoberfläche aus bedienbare Absperrvorrichtungen angebracht. Durch probeweises Schließen der Absperrvorrichtungen kann beim Ausströmen von Gasen schnell festgestellt werden, in welchem Streckenabschnitt sich der Fehler befindet.Device for displaying and identifying damaged areas on the Gas pipes laid in the ground It is known about those laid in the ground Gas lines to lay collecting lines for approximately escaping gas quantities and these Connect bus lines to display devices located above the ground. The invention relates to an improvement in these safety devices, which makes it easier to determine the location of the damaged area. According to the invention the gas pipes and the manifolds are of a gas-permeable layer surrounded in a manner known per se at individual points by an impermeable Barrier layer is divided, and there are in the same places in the manifold Shut-off devices that can be operated from the surface are attached. By trial Closing the shut-off devices can quickly be determined when gases escape the route section in which the error is located.

In der Zeichnung ist eine Ausführungsform der Einrichtung dargestellt. Es zeigen: Abb. x einen Längsschnitt, Abb. a einen Querschnitt in größerem Maßstabe.In the drawing, an embodiment of the device is shown. They show: Fig. X a longitudinal section, Fig. A a cross section on a larger scale.

Oberhalb der in der Erde gelegten Gasleitung a ist das am Mantel mit Löchern c versehene Auffangrohr b angeordnet. Die Gasleitung und das Auffangrohr sind von einer gasdurchlässigen Schicht d umgeben. Damit sich die COffnung des Sammelrohres h nicht verstopft, befindet sich über diese eine Abdeckung aus Formsteinen. An das Sammelrohr ist die Leitung k angeschlossen, die zu einer in bekannter Weise mit Zündflamme versehenen Straßenlater ne g führt. Tritt an einer Stelle des Leitungsrohres-a eine undichte Stelle auf und strömt Gas in das Sammelrohr c ein, so wird dieses in der Laterne g entzündet, und dadurch wird auf die schadhafte Stelle hingewiesen. Zur Erleichterung des Auffindens der Fehlerstellen sind an einzelnen Stellen vom Erdboden aus bedienbare Schieber h in der Sammelleitung angeordnet, und die durchlässige Schicht d ist an diesen Stellen durch eine undurchlässige Stampfungi aus Lehm o. dgl. unterbrochen. Zeigt die Lampe g eine Gasausströmung an, so werden die Schieber h nacheinander geschlossen, und zwar wird zunächst der Schieber geschlossen, der am weitesten von der Lampe entfernt ist. Auf diese Weise ergibt sich, zwischen welchen Schiebern die Fehlerstelle liegt.Above the gas pipe a laid in the ground is the one on the jacket Holes c provided collecting tube b arranged. The gas line and the collecting tube are surrounded by a gas-permeable layer d. So that the opening of the manifold h not clogged, there is a cover made of shaped stones over this. To the The manifold is connected to the line k, which is connected to a known manner Street lamp provided with a pilot light Occurs at one point on the line pipe-a a leak and gas flows into the manifold c, so this ignited in the lantern g, and this indicates the damaged spot. To make it easier to find the faults, the Ground from operable slide h arranged in the manifold, and the permeable Layer d is covered at these points by an impermeable ramming made of clay or the like. like interrupted. If the lamp g indicates an outflow of gas, the slides are h closed one after the other, namely first the slide is closed, the farthest from the lamp. In this way it emerges between which Slide the fault location.
