Description
Mundstück zum Abschliessen der Bohrlöcher beim Ausgiessen von Felspartien. Gegenstand vorliegender Erfindung ist ein Mundstück zum Abschliessen der Bohr löcher beim Ausgiessen von Felspartien.
Die Zeichnung veranschaulicht ein Aus führungsbeispiel des Erfindungsgegenstandes. Das Mundstück besteht aus einem Gummi schlauch von zum Beispiel 20 ein Länge, dessen Wandung an einem Ende dicker ist als am andern und im Abstand von etwa a cm von der breiteren Endstirnfläche eine dünne Partie b aufweist, die unter dem Ein fluss von im Innern des Mundstückes herr- sehenden Druck sieh leicht nach aussen aus biegt.
Beim Gebrauch wird das Mundstück mit seinem Ende a an ein Zuleitungsrohr für Ausgiessmaterial, z. B. Zementbrei, ange schlossen und sodann mit diesem Rohr in ein Bohrloch in der auszugiessenden Felspartie so weit eingeführt, dass sich das Mundstück zum Beispiel einige Meter weit vom Ende der Bohrung befindet. Wird nun durch das Rohr Zementbrei -unter Druck eingeleitet, so bläht sich die dünne Schlauchpartie b auf (ver- gleiche punktierte Lage e) und legt sich dicht schliessend an die Wandung der Bohrung an, so dass der vor dieser Stelle liegende Teil des Bohrloches nach aussen abgeschlossen ist und der eingespritzte Zementbrei nicht nach rückwärts entweichen kann.
Es wird dadurch das Nachbohren .der bis her stufenweise vorgetriebenen und nach Vollendung jeder Stufe ausgegossenen Bohr löcher erspart.
Mouthpiece for closing the drill holes when pouring rock areas. The subject of the present invention is a mouthpiece for closing the drill holes when pouring rock sections.
The drawing illustrates an exemplary embodiment of the subject matter of the invention. The mouthpiece consists of a rubber hose of, for example, 20 a length, the wall of which is thicker at one end than at the other and at a distance of about a cm from the wider end face has a thin section b, which under the influence of the inside of the The pressure from the mouthpiece looks slightly outward.
In use, the mouthpiece is connected with its end a to a supply pipe for pouring material, for. B. cement paste, is closed and then introduced so far with this pipe into a borehole in the rock to be poured that the mouthpiece is, for example, a few meters from the end of the hole. If cement paste is now introduced through the pipe under pressure, the thin hose section b expands (compare dotted position e) and lies tightly against the wall of the bore, so that the part of the borehole in front of this point follows is closed on the outside and the injected cement paste cannot escape backwards.
This saves the need to re-drill the drill holes that have been driven forward in stages and poured out after each stage has been completed.
