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.
