Description
Zum Bohren von Löchern in Stein und Beton werden bisher vornehmlich durch Preßluft oder elektrischen Strom angetriebene Bohrer oder Meißel verwandt. Dieses Verfahren arbeitet in hartem Gestein verhältnismäßig langsam, der Werkzeugverbrauch ist groß, und beim Abbrechen des Werkzeuges kann häufig die Bohrung nicht weitergeführt werden. Auch ist die Federung des Werkzeuges bei größeren Bohrtiefen so groß, daß der Wirkungsgrad des Verfahrens schlecht wird; zudem führt der entstehende Staub leicht zu Gesundheitsschädigungen. Neuerdings hat sich auch, besonders zum Bohren von Sprenglöchern, die Sauerstofflanze eingeführt. Bei diesem Verfahren wird ein Stahlrohr, durch das Sauerstoff geleitet wird, am vorderen Ende auf Zündtemperatur gebracht, so daß es im Sauerstoffstrom verbrennt. Die Lanze wird sodann gegen das zu bohrende Material gepreßt, das durch die große Hitze schmilzt. Das Eisenoxyd und das geschmolzene Gestein werden durch den Sauerstoff aus dem Bohrloch herausgedrückt.For drilling holes in stone and concrete are so far primarily Drills or chisels driven by compressed air or electric current. This method works relatively slowly in hard rock, the tool consumption is large, and if the tool breaks, the drilling can often not be continued will. The resilience of the tool is so great at greater drilling depths that the efficiency of the process becomes poor; in addition, the resulting dust leads easy to damage health. Lately it has also been used, especially for drilling of blast holes, the oxygen lance introduced. In this procedure, a Steel pipe, through which oxygen is passed, at the front end at ignition temperature brought so that it burns in a stream of oxygen. The lance is then against the Pressed material to be drilled, which melts due to the high heat. The iron oxide and the molten rock is forced out of the borehole by the oxygen.
Der Hauptnachteil dieses Verfahrens besteht in dem hohen Stahlverbrauch. Außerdem erstarrt bei tiefen Bohrlöchern die Schmelze auf ihrem Weg aus dem Bohrloch und versperrt dadurch der nachfolgenden Schmelze den Weg.The main disadvantage of this process is the high consumption of steel. In addition, in deep boreholes, the melt solidifies on its way out of the borehole and thereby blocks the path of the subsequent melt.
Erfindungsgemäß wird der hohe Eisenverbrauch durch Zugabe von anderen Brennstoffen in festem, flüssigem oder gasförmigem Zustand herabgesetzt. Als Brennstoffe kommen z. B. Asphalt, Teer, Öl, Petroleum, Methan, Wasserstoff usw. in Frage. Feste Brennstoffe werden in zerkleinertem oder gemahlenem Zustand zugeführt. Zur Vermeidung von zähem Schmelzfluß in dem Bohrloch und Verstopfung durch Erstarren der Schmelze wird erfindungsgemäß ein an sich bekanntes Flußmittel oder ein Flußmittelgemisch zugeführt. Es können dafür die Mittel, die den Erstarrungspunkt herabsetzen, z. B. Natriumchlorid, Natriumcarbonat, Natriumtetraborat u. a., verwendet werden.According to the invention, the high iron consumption is reduced by adding other fuels in the solid, liquid or gaseous state. As fuels come z. B. asphalt, tar, oil, petroleum, methane, hydrogen, etc. in question. Solid fuels are supplied in a crushed or ground state. In order to avoid a tough melt flow in the borehole and blockage due to solidification of the melt, a flux known per se or a flux mixture is supplied according to the invention. It can be the means that lower the freezing point, z. B. sodium chloride, sodium carbonate, sodium tetraborate, etc. can be used.
Diese Flußmittel können in der Lanze getrennt oder gemischt mit dem Brennstoff untergebracht sein oder während des Bohrens zugeführt werden.These fluxes can be separated in the lance or mixed with the Be housed fuel or fed during drilling.
Zur Durchführung des geschilderten Verfahrens werden Stahlrohre verwendet, die ineinandergesteckt sind. Die Durchmesser sind dabei so zu wählen, daß immer geeignet große Zwischenräume bleiben. In der Regel wird durch das Mittelrohr der Sauerstoff zugeführt, und die Zwischenräume zwischen den einzelnen Rohren werden erfindungsgemäß zum Zuführen oder Durchleiten der zusätzlichen Stoffe verwendet. Der Schmelzfluß entweicht durch den Raum zwischen dem äußersten Rohr und der Wand des Bohrloches.Steel pipes are used to carry out the described process, that are nested. The diameters are to be chosen so that always suitable large spaces remain. As a rule, the Oxygen is supplied, and the spaces between the individual tubes are used according to the invention for supplying or passing through the additional substances. The melt flow escapes through the space between the outermost tube and the wall of the borehole.
Die Zeichnung zeigt ein Beispiel für die Vorrichtung zur Ausübung des Verfahrens. Die Abb. i gibt die Gesamtanordnung schematisch, die Abb. 2 einen Querschnitt durch die Sauerstofflanze wieder.The drawing shows an example of the device for exercising of the procedure. Fig. I shows the overall arrangement schematically, Fig. 2 a Cross-section through the oxygen lance again.
Ein Preßluftbehälter i liefert über ein Reduzierventil 2 Druckluft in den Raum 3 des Ölbehälters 4 und drückt das öl als zusätzlichen Brennstoff über die Leitung 5 in die Sauerstofflanze 6. Diese besteht aus drei ineinandergesteckten Stahlrohren Al, A2 und A3, welche den Raum B für das Flußmittel, den Raum C für das öl und den Raum D für den Sauerstoff bilden.A compressed air container i supplies compressed air via a reducing valve 2 in the space 3 of the oil container 4 and presses the oil as additional fuel the line 5 into the oxygen lance 6. This consists of three nested Steel pipes Al, A2 and A3, which the space B for the flux, the space C for form the oil and the space D for the oxygen.
