Abstract

Die Erfindung betrifft eine Vorrichtung zur Entwässerung abfallend gerichteter Bohrlöcher bei der Gasabsaugung. Ein an jeweils eine Druckluft- und eine Steigleitung anschließbarer Tauchkörper wird in ein Bohrloch abgesenkt. Der Tauchkörper weist eine über ein Kugelventil verschließbare Öffnung auf. Mittels Druckluft wird das im Tauchkörper angesammelte Wasser in die Steigleitung gedrückt, wobei das Ventil selbsttätig geschlossen bleibt. Anschließend wird die Druckluftzufuhr unterbrochen und das im Bohrloch stehende Wasser öffnet das Ventil und strömt in den Tauchkörper. Die Vorgänge wiederholen sich solange wie sich Wasser im Bohrloch ansammelt.
