Zusatz zum Patent 933Addendum to patent 933

In dem Patent 933 328 ist ein Verfahren zum Verbinden von Gesteinsschichten mittels Gebirgsanker im Bergbau beschrieben, um die geschaffenen Hohlräume offen zu halten. Hierbei ist vorgeschlagen worden, das Bohren eines Ankerloches und das Setzen des Gesteinsankers in einem Arbeitsgang derart erfolgen zu lassen, daß der Bohrer selbst nach dem Bohrvorgang im Gestein verankert wird. Dieses Verfahren bringt eine wesentliche Vereinfachung des Ankeranbäues, bei dem eine besondere Ausbildung des Bohrers notwendig ist. Es ist z. B. vorgeschlagen, den Bohrerkopf oder andere Bohrerteile, beispielsweise eine Hülse, die über die Bohrstange verschiebbar und drehbar ist, im Bereich des Bohrkopfes nach dem Bohrvorgang zu spreizen. Auch kann nach dem Bohrvorgang der Bohrkopf durch Eintreiben eines Keiles od. dgl. gespreizt werden.In the patent 933 328 there is a method for connecting rock strata by means of rock bolts described in mining in order to keep the created cavities open. It is suggested here drilling an anchor hole and setting the rock anchor in one operation to be done in such a way that the drill is anchored in the rock even after the drilling process. This method brings a significant simplification of the anchor cultivation, in which a special Training of the drill is necessary. It is Z. B. suggested the drill head or other drill parts, for example, a sleeve that is slidable and rotatable over the drill rod, in the area to spread the drill head after the drilling process. The drill head can also after the drilling process by driving in a wedge or the like. Be spread.

In dem Hauptpatent ist auch schon vorgeschlagen worden, das Bohrloch mit Zementmilch auszufüllen, wobei diese Zementmilch durch die Längsbohrung der Bohrstange und/oder der Hülse und durch Querbohrungen in das Bohrloch eingepreßt wird.In the main patent it has also been suggested to fill the borehole with cement milk, this cement milk through the longitudinal bore of the drill rod and / or the sleeve and is pressed into the borehole through transverse bores.

Um dieses Verfahren zu vereinfachen, wird gemaß der Erfindung vorgeschlagen, einen BohrerIn order to simplify this method, it is proposed according to the invention, a drill

nach dem Bohrvorgang im Bohrloch mit Zementmilch od. dgl. zu vergießen, ohne daß der Bohrkopf oder Teile dieses Bohrers im Bereich des Bohrkopfes gespreizt werden. Es hat sich gezeigt, daß auch 'diese Art des Ankersetzens in vielen Fällen genügt, um die übereinanderliegenden Gesteinsschichten miteinander fest zu verbinden.after the drilling process in the borehole with cement milk or the like. To be poured without the drill head or parts of this drill are spread in the area of the drill head. It has shown, that this type of anchoring is also sufficient in many cases to remove the strata of rock lying on top of one another to be firmly connected to each other.

Der Bohrkopf, dessen Durchmesser wie bei allen bisher bekannten Gesteinsbohren! größer ist alsThe drill head, the diameter of which is the same as in all rock drilling known to date! is greater than

ίο der Durchmesser des Schaftes, wird durch die Zementfüllung, die den Raum zwischen Bohrschaft und Bohrlochwandung ausfüllt, mit dem Gestein verbunden, etwa wie ein Dübel in einem Bohrloch. Man erreicht hierdurch eine Verankerung in den tragenden Gesteinsschichten. Bai der praktischen Ausführung kann der Bohrer, wie in dem- Hauptpatent vorgeschlagen wurde, mit einer konzentrischen Bohrung und mehreren in verschiedenen Höhen angebrachten Querbohrungen versehen sein.ίο the diameter of the shaft, is determined by the cement filling, which fills the space between the drill shaft and the borehole wall, connected to the rock, like a dowel in a borehole. This achieves an anchoring in the load-bearing rock layers. Bai the practical Execution can be the drill, as was proposed in the main patent, with a concentric Borehole and several transverse bores made at different heights.

Hierdurch wird ein Absaugen des Gesteinsstaubes beim Bohren ermöglicht, andererseits kann durch diese Bohrung die Zementmilch od. dgl. durch diese Bohrungen in das Bohrloch eingepreßt werden.This enables the rock dust to be extracted while drilling, on the other hand, through this hole the cement milk od. Like. Be pressed through these holes in the borehole.

Zur Durchführung des Verfahrens gemäß der Erfindung kann auch ein ungespreizter Bohrer verwendet werden, bei dem die mit den Bohrungen versehene Bohrstange mit einem oder mehreren Drähten schraubenförmig umgeben ist, die durch Schweißen, Löten od. dgl. angebracht sein können.An unspread drill can also be used to carry out the method according to the invention be, in which the drill rod provided with the holes with one or more Wires is surrounded helically, which od by welding, soldering. The like. Can be attached.

Selbstverständlich könnten die durch die Drahte entstehenden Wülste auch beim Schmieden oder Walzen der Bohrstange angebracht werden. Hierdurch erreicht man, daß nicht nur der Bohrkopf - und die übliche Ankerplatte, sondern auch der Schaft des Bohrers unmittelbar zum Verbinden der einzelnen Gesteinsschichten herangezogen wird. Selbstverständlich könnten auch scheibenförmige Erhöhungen oder sonstige Wülste auf dem Bohrerschaft angebracht sein, um die Verankerung zu erhöhen. Of course, the beads created by the wires could also be used during forging or Rolls of the boring bar are attached. This achieves that not only the drill head - And the usual anchor plate, but also the shaft of the drill directly to connect the individual rock layers is used. Of course, disc-shaped Elevations or other beads may be attached to the drill shaft in order to increase the anchorage.

Auch bei einem solchen ungespreizten Bohrer wird, wie bei dem Hauptpatent, eine Bohrkrone vorgesehen, deiren Standzeit nicht größer ist, als zum Bohren eines Ankerloches von bestimmter Tiefe in einem Gestein bestimmter Härte notwendig ist. Die Bohrschneiden, die Bohrköpfe und die Bohrstangen können aus dem gleichen Werkstoff gefertigt werden.Even with such an unspread drill, as in the main patent, a drill bit is used provided, deiren service life is not greater than for drilling an anchor hole of certain Depth in a rock of a certain hardness is necessary. The cutting edges, the drilling heads and the Boring bars can be made from the same material.

In der Zeichnung ist ein Ausführungsbeispiel eines Bohrers zur Ausübung des Verfahrens im Schnitt durch ein Bohrloch dargestellt.The drawing shows an embodiment of a drill for performing the method in Section through a borehole shown.

Der Bohrer besteht aus der Bohrstange 1 und dem Bohrkopf 2, mit denen ein Bohrloch 19 hergestellt wird. Die einzelnen Gesteinsformationen 14, 15, 16, 17 und 18 werden durchbohrt, wovon die Schicht 14 das unmittelbar Hangende bzw. Liegende darstellt, das an der festen Gesteinsschicht 18 befestigt werden soll. Der beim Bohren anfallende Gesteinsstaub wird durch die Querbohrungen 13 des Schaftes 1 und durch die konzentrische Bohrung 9 abgesaugt. Hat der Bohrer die erforderliche Tiefe erreicht, so dienen die Bohrungen 9'und 13 zum Einpressen von Zementmilch od. dgl. in den verbleibenden Ringraum des Bohrloches 19 zwischen Bohrlochwandung und Bohrstange 1. Nach dem' Hartwerden der Zementfüllung wird auf das mit Gewinde versehene Ende des Bohrers die Ankerplatte ii aufgesetzt und mittels der Mutter 20 angezogen.The drill consists of the drill rod 1 and the drill head 2, with which a borehole 19 is made will. The individual rock formations 14, 15, 16, 17 and 18 are drilled through, of which the Layer 14 represents that directly hanging or lying on the solid rock layer 18 is to be attached. The rock dust that accumulates during drilling is passed through the transverse bores 13 of the shaft 1 and through the concentric bore 9 sucked off. When the drill has reached the required depth, the bores 9 'and 13 are used for pressing cement milk or the like into the remaining annular space of the borehole 19 between Borehole wall and drill rod 1. After the cement filling has hardened, the threaded end of the drill, the anchor plate ii is placed and by means of the nut 20 attracted.

Zweckmäßig wird der Übergang zwischen dem Bohrkopf 2 und der Bohrstange 1 kegelig gestaltet, damit die Zementfüllung im Bereich des Bohrkopfes 2 nicht nur in axialer, sondern auch in radialer Richtung belastet wird.The transition between the drill head 2 and the drill rod 1 is expediently designed to be conical, so that the cement filling in the area of the drill head 2 not only in the axial, but also in the radial Direction is loaded.

Um die einzelnen Gesteinsformationen miteinander noch besser zu verbinden, werden Drähte 21 schraubenförmig um die Bohrstange 1 gelegt und durch Schweißen, Löten od. dgl. an dieser befestigt. Die Drähte können jeden beliebigen Querschnitt aufweisen; die Wülste können auch mit dem Schaft ι beim Schmieden öder Walzen aus einem Stück hergestellt werden. Es ist auch nicht notwendig, daß die Drähte eine ununterbrochene Schraubenlinie darstellen, die Drähte könnten absatzweise aufgeschweißt werden, oder es könnten ringförmige Teile mit dem Schaft verbunden werden. -To the individual rock formations with each other To connect even better, wires 21 are laid helically around the boring bar 1 and by welding, soldering or the like. Attached to this. The wires can have any cross-section exhibit; the beads can also with the shaft ι when forging or rolling from one Piece to be produced. It is also not necessary that the wires be uninterrupted Represent helical lines, the wires could or could be intermittently welded annular parts are connected to the shaft. -

Durch das vorliegende Verfahren sowie den dargestellten ungespreizten Bohrer wird der Ankerausbau gegenüber den Vorschlägen des Haupt- g0 patentes noch weiter vereinfacht.By the present method, as well as unexpanded drill shown of the expansion anchor is compared to the proposals of the main g 0 patentes further simplified.
