Description
In dem Patent 303841 ist ein Verfahren zum Festlegen von Richtmitteln beschrieben, die zur Führung des Bohrmeißels in Bohrlöchern in festem Gebirge dienen. Das Verfahren besteht darin, daß das als Richtmittel dienende Keilstück in eine von ihm selbst mitgeführte, zu gegebener Zeit freigegebene Erhärtungsmasse .eingebettet wird. Wie bereits angedeutet, ist bei Durchführung dieses Verfahrens das Vorhandensein von festem Gebirge Bedingung, und ferner ist natürlich vorausgesetzt, daß die Erhärtungsmasse eine Bindung mit ihrer Umgebung eingeht. Diese Vorbedingungen treffen nun nicht immer zu.In the patent 303841 a method for setting directional means is described, which are used to guide the drill bit in boreholes in solid rock. The procedure consists in the fact that the wedge serving as a guide is inserted into a The hardening compound released at the appropriate time is embedded. As already indicated, the presence of solid rock is when this method is carried out Condition, and furthermore, of course, is assumed that the hardening compound forms a bond with its surroundings. These Preconditions do not always apply.
Beispielsweise wird sich das angegebene Verfahren in Tonschichten nicht durchführen lassen. Diesem Mangel soll durch die vorliegende Erfindung· abgeholfen werden, bei der somit zum an sich gleichem Zwecke, wie im Hauptpatent angegeben, das Richtmittel in solchen Schichten festgelegt werden soll, die eine Bindung mit einer Erhärtungsmasse nicht eingehen.For example, the specified method cannot be carried out in layers of clay. This deficiency is to be remedied by the present invention, in which thus for the same purpose as in Main patent stated that the directional means should be specified in those layers that do not form a bond with a hardening compound.
Gemäß der Erfindung findet in diesem Falle ein Richtmittel Anwendung, bei dem in Verlängerung des Keilrohres ein Flügel vorgesehen ist, der in den Bohrlochgrund: eingelassen, im allgemeinen also eingetrieben wird, und welcher die Verdrehung des Richtmittels verhindert. Mittels dieses Flügels wird somit das Keilstück in dem Bohrlochgrund verankert. Der Flügel kann beispielsweise aus einem schwertartigen Gebilde von vorzugsweise kreuzförmigem Querschnitt bestehen, das am unteren Ende des Keilrohres befestigt wird.According to the invention, a directional means is used in this case in which in extension of the wedge tube a wing is provided, which is embedded in the bottom of the borehole, In general, therefore, is driven, and which the rotation of the straightening means prevented. The wedge is anchored in the bottom of the borehole by means of this wing. The wing can, for example, preferably consist of a sword-like structure consist of a cross-shaped cross-section attached to the lower end of the wedge tube will.
Auf der Zeichnung ist ein im Sinne der Erfindung ausgebildetes Richtmittel in seinen wesentlichen, für das Verständnis der Erfindung ausreichenden Teilen dargestellt. Es zeigenIn the drawing, a directed means designed in accordance with the invention is in its essential, sufficient for an understanding of the invention parts shown. It demonstrate
Fig. ι und 2 zwei gegeneinander um 900 verdrehte Seitenansichten mit teilweisem Schnitt,Fig. Ι and 2 two mutually rotated 90 0 side views with partial section,
Fig. 3 einen Querschnitt nach Linie A-B der Fig. ι und 2.3 shows a cross section along line AB of FIGS.
Am unteren Ende des Keilrohres α ist ein Schwert h befestigt, das aus einem nach unten sich verjüngenden Flachstüek c mit aufgenieteten T-Eisen d besteht. Am oberen Ende sind die Ränder des Flachstückes umgebogen und so Lappen e gebildet, mittels deren das Flachstück an dem Rohr α befestigt wird. Die Stege der T-Eisen sind ebenso wie die untere Kante des Flachstückes zugeschärft, um .eitt Hineindrücken in den Bohrlochgrund zu erleichtern. At the lower end of the wedge tube α a sword h is attached, which consists of a downwardly tapering flat piece c with riveted T-iron d . At the upper end, the edges of the flat piece are bent over to form flaps e , by means of which the flat piece is attached to the tube α. The webs of the T-irons, like the lower edge of the flat piece, are sharpened to make it easier to push them into the bottom of the borehole.
An der für die Ablenkung des Bohrmeißels in Betracht kommenden Stelle des Bohrloches wird das mit Zement oder einer anderen geeigneten Beschwerungsmasse gefüllte Keilrohr α durch festes Aufsetzen des Schwertes verankert.At the point of the borehole that is considered for the deflection of the drill bit, the wedge tube α filled with cement or another suitable weighting compound is anchored by firmly placing the sword.
Zur Erhöhung der Wirkung ist, wie aus denTo increase the effect is how out of the
Fig. ι und 3 ersichtlich, die Längsachse des Schwertes gegenüber derjenigen des Keilrohres geneigt. Das Rohr wird somit beim Eintreiben des Schwertes einseitig gegen die Bohrlochwandung gepreßt.Fig. Ι and 3 can be seen, the longitudinal axis of the sword compared to that of the wedge tube inclined. The pipe is thus pressed on one side against the borehole wall when the sword is driven in.
