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. The invention relates to a device for drainage sloping holes in the gas extraction. One each to a compressed air and a riser connectable immersion body is lowered into a borehole. The immersion body has a ball valve lockable opening. Using compressed air, this is Water immersed in the riser, the valve remains closed automatically. The compressed air supply is then interrupted and the water in the borehole opens the valve and flows into the immersion body. Repeat the operations as long as water accumulates in the borehole.
