Description

Verfahren zur Feststellung von Undichtheiten an unterirdisch verlegten Wasserleitungen Die Erfindung l)etrifft ein Verfahren zur Feststellung von Undichtbeiten an unterirdisch verlegten Wasserleitungen.Procedure for the detection of leaks in underground ones Water pipes The invention l) relates to a method for determining leaks on underground water pipes.

Bisher war es üblich, Wasserleitungen mittels Horchtlosen oder Geophonen, also durch Geräuschfeststellungen auf Ctndiclltheiten zu prüfen. Diese Maßnahme ist aller in vielen Fällen deshalb unvollkommen, weil auf Grund bestimmter Gegebenheiten es nicht zu solchen Geräuschentwicklungen und -ülertragungen kommt, die sich mit diesen Horchdosen oder Geophonen feststellen lassen. Das ist z. B. insbesondere dann der Fall, wenn schwache Druckverhältnisse in der Wasserleitung vorliegen, oder diese Leitung sehr tief liegt, oder die über der Wasserleitung liegende Erdschicht die Geräuschweiterleitung dämpft, so daß das Geräusch bereits abgeklungen oder so weit verringert ist, daß es mit diesenHorchgeräten nicht mehr festgestellt werden kann. So far it has been customary to construct water pipes by means of unheard or geophones, So to check for abnormalities through noise detection. This measure is all imperfect in many cases because of certain circumstances there are no such noise developments and noise transmissions that deal with have these listening boxes or geophones detected. This is e.g. B. in particular this is the case when there are weak pressure conditions in the water pipe, or this pipe is very deep, or the layer of earth above the water pipe the sound transmission attenuates so that the sound has already subsided or something is much reduced that it can no longer be detected with these listening devices can.

Um vorzugsweise diesen Mängeln zu begegnen, wird erfindungsgemäß vorgeschlagen, die abzuprüfende Leitung nach ihrer Entleerung mit einem spezifisch leichteren Gas als Luft vorzugsweise \N'asserstoff zu füllen und alsdann diese Leitung mit an sich bekannten Gasspürgeräten auf Gasundichtheit zu überprüfen. In order to preferably address these deficiencies, the invention suggested that the line to be checked after it was emptied with a specific lighter gas than air, preferably hydrogen, and then this line to check for gas leaks with gas detection devices known per se.

I)urch diesen Vorschlag lassen sich schnell und mit Sicherheit und unter allen gegebenen Verhältnissen Undichtheiten an unterirdisch verlegten Wasserleitungen feststellen, auch schon solche von geringfügigen Ausmaßen, und zwar ohne eventuell sich schädlich auswirkende Druckaufwendungen. I) With this suggestion you can quickly and with certainty and Under all given conditions there are leaks in underground water pipes notice, even those of minor dimensions, namely without potentially harmful printing expenses.
