Description

Die Erfindung betrifft ein Bohrgerät zum Erstellen einer Bohrsäule im Boden gemäß dem Oberbegriff des Anspruchs 1, mit einem Mast, einem Bohrantrieb, welcher an einem Schlitten angeordnet ist, der entlang dem Mast verschiebbar gelagert ist, einem Bohrrohr, welches zum Erstellen eines Bohrlochs durch den Bohrantrieb drehend antreibbar und entlang dem Mast verschiebbar ist, einem am Bohrrohr angeschlossenen Rohrbunker mit einem Speicherraum für Füllmaterial zum Verfüllen des Bohrlochs beim Ziehen des Bohrrohrs, und einer Verschlusseinrichtung, durch welche ein Durchgang für Füllmaterial vom Rohrbunker zum Bohrrohr verschließbar ist.The invention relates to a drill for creating a drill column in the ground according to the preamble of claim 1, comprising a mast, a drill drive, which is arranged on a carriage which is displaceably mounted along the mast, a drill pipe, which for creating a borehole through the Drill drive is rotatably driven and slidable along the mast, a tubular bunker connected to the drill pipe with a storage space for filling material for filling the borehole when pulling the drill pipe, and a closure device, through which a passage for filling material from the pipe bunker to the drill pipe is closable.

Die Erfindung betrifft ferner ein Verfahren gemäß dem Oberbegriff des Anspruchs 7 zum Erstellen einer Bohrsäule im Boden, bei dem ein Bohrrohr in den Boden mittels eines Bohrantriebes drehend eingebracht wird, welcher an einem Schlitten angeordnet ist, der entlang eines Mastes in einer Bohrrichtung verschiebbar ist, und nach Erreichen einer gewünschten Tiefe das Bohrrohr zurückgezogen und das Bohrloch mit Füllmaterial aus einem Rohrbunker über das Bohrrohr verfüllt wird.The invention further relates to a method according to the preamble of claim 7 for creating a drill column in the ground in which a drill pipe is rotationally inserted into the ground by means of a drill drive which is arranged on a carriage which is displaceable along a mast in a drilling direction, and after reaching a desired depth the drill pipe is withdrawn and the wellbore is filled with fill material from a pipe bunker via the drill pipe.

Eine gattungsgemäße Vorrichtung und ein gattungsgemäßes Verfahren sind aus der EP 1 580 325 A1 bekannt. Diese Druckschrift offenbart ein Bauarbeitsgerät mit einem Mast, an dem ein Drehantrieb längs verfahrbar ist. Bodenseitig an dem Drehantrieb ist ein mehrteiliges Bohrrohrgestänge angeordnet. In einem oberen Bereich des Bohrrohgestänges ist ein Rohrbunker vorgesehen, der zur Aufnahme von Füllmaterial dient, welches beim Ziehen des Bohrrohrgestänges über das Gestänge in den entstehenden Hohlraum eingeleitet werden kann.A generic device and a generic method are from the EP 1 580 325 A1 known. This document discloses a construction implement with a mast on which a rotary drive is moved longitudinally. Bodenseitig on the rotary drive a multi-part drill pipe is arranged. In an upper region of the Bohrrohgestänges a tubular bunker is provided, which serves to receive filling material, which can be introduced when pulling the Bohrrohrgestänges over the linkage in the resulting cavity.

Nach der EP 1 580 325 A1 ist vorgesehen, das mehrteilige Bohrrohrgestänge in mehreren Schritten zu ziehen. Hierbei wird durch Hochfahren des Schlittens am Mast ein Gestängeabschnitt aus dem Boden herausgezogen, dieser sodann entfernt, der Schlitten wieder heruntergefahren und mit dem darunter liegenden Rohrabschnitt verbunden. Die Länge des bei jedem Schritt herausgezogenen Rohrabschnittes und folglich die Arbeitsgeschwindigkeit ist daher durch den Schlittenhub und somit die Mastlänge beschränkt.After EP 1 580 325 A1 is planned to pull the multi-part drill pipe in several steps. Here, a boom section is pulled out of the ground by raising the carriage on the mast, this then removed, the carriage is shut down again and connected to the underlying pipe section. The length of the pipe section withdrawn at each step, and consequently the working speed, is therefore limited by the carriage stroke and thus the length of the mast.

Weitere Bohrgeräte mit einem Rohrbunker gehen aus der US 5,647,690 , der US 3,303,656 und der US 2003/0123937 A1 hervor.Further drills with a tube bunker go out of the US 5,647,690 , of the US 3,303,656 and the US 2003/0123937 A1 out.

Die US 3,604,214 und die EP 0 831 180 A1 offenbaren jeweils Bodenbearbeitungsgeräte mit einem Bohrgestänge, das mittels eines Drehantriebes drehbar ist. Oberhalb des Drehantriebes ist dabei jeweils ein Einfülltrichter angeordnet, über den Material in das Innere des Bohrgestänges einleitbar ist.The US 3,604,214 and the EP 0 831 180 A1 each disclose tillage equipment with a drill pipe which is rotatable by means of a rotary drive. Above the rotary drive in each case a hopper is arranged, via the material in the interior of the drill string can be introduced.

Aufgabe der Erfindung ist es, ein gattungsgemäßes Bohrgerät und ein gattungsgemäßes Verfahren anzugeben, die bei hoher Vielseitigkeit und Wirtschaftlichkeit eine besonders hohe Arbeitsgeschwindigkeit erlauben. The object of the invention is to provide a generic drill and a generic method that allow high versatility and cost-effectiveness, a particularly high operating speed.

Die Aufgabe wird erfindungsgemäß durch ein Bohrgerät mit den Merkmalen des Anspruchs 1 und ein Verfahren mit den Merkmalen des Anspruchs 7 gelöst. Bevorzugte Ausführungsbeispiele sind in den abhängigen Ansprüchen angegeben.The object is achieved by a drill with the features of claim 1 and a method having the features of claim 7. Preferred embodiments are given in the dependent claims.

Das erfindungsgemäße Bohrgerät ist unter anderem dadurch gekennzeichnet, dass der Rohrbunker in Bohrrichtung oberhalb des Bohrantriebes angeordnet und am Bohrrohr angeschlossen ist.Among other things, the drilling rig according to the invention is characterized in that the tubular bunker is arranged above the drilling drive in the drilling direction and connected to the drill pipe.

Ein Grundgedanke der Erfindung liegt darin, den Rohrbunker auf der dem Bohrrohr und insbesondere dessen Spitze abgewandten, oberen Seite des Bohrantriebes anzuordnen, wodurch es möglich ist, das Bohrrohr unmittelbar an den Bohrantrieb heranzuführen, ohne dass dazwischenliegende Elemente zum Speichern von Füllmaterial erforderlich sind. Verglichen mit dem Stand der Technik, gemäß dem der Rohrbunker unterhalb des Drehantriebes vorgesehen ist, kann nach der Erfindung der Bohrantrieb mit dem Schlitten somit näher an den Bohrlochrand herangefahren werden, ohne dass diese Bewegung durch den Rohrbunker behindert wird. Somit wird bei gleicher Mastlänge der mögliche Schlittenhub vergrößert, so dass längere Bohrrohrabschnitte verwendet werden können. Folglich wird auch die Zahl der erforderlichen Ein- und Ausbauvorgänge von Bohrrohrabschnitten reduziert und die Arbeitsgeschwindigkeit erhöht.A basic idea of the invention is to arrange the tubular bunker on the upper side of the drill drive facing away from the drill pipe and in particular its tip, whereby it is possible to bring the drill pipe directly to the drill drive, without intervening elements for storing filler material are required. Compared with the prior art, according to which the tube bunker is provided below the rotary drive, the drill drive with the slide can thus be moved closer to the edge of the drill hole according to the invention, without this movement being hindered by the tube bunker. Thus, with the same mast length, the possible carriage stroke is increased, so that longer drill pipe sections can be used. Consequently, the number of required installation and removal operations of drill pipe sections is reduced and the working speed is increased.

Grundsätzlich ist es möglich, den Rohrbunker drehfest am Bohrrohr anzuordnen, wodurch ein konstruktiv besonders einfaches Bohrgerät geschaffen wird. Eine besonders bevorzugte Ausführungsform besteht jedoch darin, dass der Rohrbunker mit dem Schlitten drehfest verbunden ist und relativ zum Bohrrohr drehend gelagert ist. Dies ermöglicht ein besonders einfaches Befüllen des Rohrbunkers, da sich dessen Position beim Bohrbetrieb nicht ändert. Geeigneterweise ist der Rohrbunker unmittelbar mit dem Schlitten verbunden.In principle, it is possible to rotate the pipe bunker to be arranged on the drill pipe, whereby a structurally particularly simple drill is created. A particularly preferred embodiment, however, is that the tube bunker is rotatably connected to the carriage and is mounted rotatably relative to the drill pipe. This allows a particularly simple filling of the tube bunker, since its position does not change during drilling operation. Suitably, the tubular bunker is directly connected to the carriage.

Für einen besonders vielseitigen Betrieb ist das Bohrrohr geeigneterweise mehrteilig ausgebildet, wobei die einzelnen Rohrabschnitte durch lösbare Kupplungen miteinander verbunden sind. Dies ermöglicht es beispielsweise, einen Bewehrungskorb in das Bohrrohr einzubauen, der dann mitsamt dem Füllmaterial durch das untere Ende des Bohrrohres in den Boden eingebracht wird.For a particularly versatile operation, the drill pipe is suitably designed in several parts, wherein the individual pipe sections are connected to each other by releasable couplings. This makes it possible, for example, to install a reinforcement cage in the drill pipe, which is then introduced together with the filling material through the lower end of the drill pipe in the ground.

Erfindungsgemäß ist eine Verschlusseinrichtung vorgesehen, durch welche ein Durchgang für Füllmaterial vom Rohrbunker zum Bohrrohr verschließbar ist. Dies ist insbesondere bei der Verwendung mehrteiliger Bohrrohre vorteilhaft. Die Verschlusseinrichtung kann beispielsweise oberhalb des Bohrantriebes, insbesondere zwischen Rohrbunker und Bohrantrieb, vorgesehen sein. Sie weist insbesondere eine Sperrklappe auf. Alternativ oder zusätzlich kann eine Verschlusseinrichtung auch unterhalb des Bohrantriebes angeordnet werden.According to the invention, a closure device is provided, by means of which a passage for filler material from the tube bunker to the drill pipe can be closed. This is particularly advantageous when using multi-part drill pipes. The closure device can for example, be provided above the drill drive, in particular between pipe bunker and drill drive. In particular, it has a blocking flap. Alternatively or additionally, a closure device can also be arranged below the drill drive.

Der Arbeitshub des Bohrgerätes kann vorteilhafterweise weiter dadurch erhöht werden, dass der Rohrbunker, insbesondere zusammen mit dem Bohrrohr, gegenüber dem Schlitten axial verschiebbar und feststellbar ist. So kann beispielsweise am Schlitten ein Linearantrieb zum Verfahren des Rohrbunkers vorgesehen sein.The working stroke of the drill can advantageously be further increased by the fact that the tubular bunker, in particular together with the drill pipe, relative to the carriage is axially displaceable and lockable. Thus, for example, be provided on the carriage, a linear drive for moving the pipe bunker.

Erfindungsgemäß ist es ferner, dass das Bohrrohr unterhalb des Drehantriebes drehfest und lösbar mit einer Abtriebswelle des Drehantriebes verbunden ist, wodurch die Vielseitigkeit des erfindungsgemäßen Bohrgerätes erhöht sein kann. Hierzu kann eine lösbare Bohrgestängekupplung vorgesehen sein.According to the invention it is further that the drill pipe below the rotary drive rotatably and releasably connected to an output shaft of the rotary drive, whereby the versatility of the drilling device according to the invention can be increased. For this purpose, a detachable drill pipe coupling can be provided.

Ein besonders zuverlässiger Betrieb des Bohrgerätes wird dadurch ermöglicht, dass im Rohrbunker ein Füllstandssensor vorgesehen ist. Insbesondere kann der Füllstandssensor eine vom Rohrbunker beabstandete Anzeigeeinrichtung aufweisen. Der Füllstandssensor kann beispielsweise einen Ultraschallsensor aufweisen.A particularly reliable operation of the drill is made possible by the fact that a level sensor is provided in the tube bunker. In particular, the fill level sensor may have a display device spaced from the tube bunker. The fill level sensor may, for example, comprise an ultrasonic sensor.

Ein konstruktiv besonders einfaches Bohrgerät ist dadurch gegeben, dass die Abtriebswelle des Bohrantriebes als Hohlwelle ausgebildet ist, an deren einen Seite das Bohrrohr zumindest abschnittsweise verläuft und auf deren anderen Seite der Rohrbunker angeordnet ist. In diesem Fall kann der Füllmaterialtransport zwischen Rohrbunker und dem Bohrrohr in besonders einfacher Weise durch die Hohlwelle erfolgen. Zur Drehmomenteinleitung kann die Abtriebswelle beispielsweise eine Verzahnung, insbesondere eine Keilverzahnung aufweisen.A structurally particularly simple drill is given by the fact that the output shaft of the drill drive is designed as a hollow shaft, on one side of the drill pipe extends at least partially and on the other side of the tube bunker is arranged. In this case, the Füllmaterialtransport between pipe bunker and the drill pipe can be done in a particularly simple manner by the hollow shaft. For torque introduction For example, the output shaft may have a toothing, in particular a spline.

Ferner ist es erfindungsgemäß, dass der Rohrbunker einen im Wesentlichen zylindrischen Speicherbereich aufweist, an dem sich unten ein im Wesentlichen konischer Auslassbereich anschließt. An diesem konischen Auslassbereich kann das Bohrrohr, insbesondere über die Abtriebswelle, angeschlossen sein. Der Rohrbunker ist trichterförmig aufgebaut und oben offen. Er kann auch einen Deckel aufweisen.Furthermore, it is according to the invention that the tube bunker has a substantially cylindrical storage area, which is followed by a substantially conical outlet area at the bottom. The drill pipe, in particular via the output shaft, can be connected to this conical outlet region. The tube bunker is funnel-shaped and open at the top. He may also have a lid.

Das erfindungsgemäße Verfahren ist unter anderem dadurch gekennzeichnet, dass der Rohrbunker auf dem Schlitten drehfest zu diesem angeordnet und mit diesem verschoben wird. Das Verfahren wird mit einem erfindungsgemäßen Bohrgerät durchgeführt, wodurch sich die in diesem Zusammenhang erläuterten Vorteile erzielen lassen.The method according to the invention is characterized, inter alia, by the fact that the tube bunker is arranged rotatably on the carriage and displaced therewith. The method is carried out with a drill according to the invention, whereby the advantages explained in this connection can be achieved.

Unter einem Rohrbunker kann insbesondere ein Füllgutspeicher verstanden werden, der in Verlängerung eines Bohrrohres, bevorzugt koaxial, an dem Bohrrohr anbringbar ist.Under a bunker can be understood in particular a product storage, which is in extension of a drill pipe, preferably coaxially attached to the drill pipe.

Durch Betätigen des Bohrantriebes 11 kann das Bohrrohr 6 in Rotation versetzt werden. Durch Verfahren des Schlittens 22 kann das Bohrrohr 6 über den Bohrantrieb 11 axial in Bohrrichtung verschoben werden. Das Bohrrohr 6 ist mit der Abtriebswelle 19 über eine unten an der Abtriebswelle 19 angeordnete, lösbare Rohrkupplung 18 gekoppelt.On the carriage 22 designed as a rotary drive drill drive 11 is provided at the output shaft 19, a drill pipe 6 rotatably and, for example, axially fixed. By operating the drill drive 11, the drill pipe 6 can be set in rotation. By moving the carriage 22, the drill pipe 6 can be moved axially over the drill drive 11 in the drilling direction. The drill pipe 6 is coupled to the output shaft 19 via a detachable pipe coupling 18 arranged at the bottom on the output shaft 19.

Das Bohrrohr 6 ist mehrteilig mit mehreren Rohrelementen ausgebildet, die über lösbare Rohrkupplungen miteinander verbunden sind. Unten am Bohrrohr 6 ist ein Verdrängungsbohrkopf 80 vorgesehen.The drill pipe 6 is formed in several parts with a plurality of tubular elements which are connected to each other via detachable pipe couplings. At the bottom of the drill pipe 6, a displacement drill head 80 is provided.

Der Bohrantrieb 11 weist ein Antriebsteil 12 auf, in dem ein Hydraulikdrehmotor angeordnet ist, sowie ein bodenseitig hieran angeordnetes, ringartiges Getriebeteil 13, das zur Drehmomentübertragung vom Hydraulikmotor zum Bohrrohr 6 dient.The drill drive 11 has a drive part 12, in which a hydraulic rotary motor is arranged, as well as a bottom-side arranged thereon, ring-like transmission part 13, which serves for torque transmission from the hydraulic motor to the drill pipe 6.

Zum Speichern von Füllgut ist oberhalb des Bohrrohres 6 in Verlängerung seiner Längsachse ein Rohrbunker 30 vorgesehen. Dieser Rohrbunker 30 weist einen zylindrischen Speicherbereich 33 zur Aufnahme von Füllgut auf, an den sich bodenseitig ein konischer Auslassbereich 34 anschließt. Der Rohrbunker 30 ist oberhalb des Bohrantriebes 11 und des Schlittens 22, das heißt auf der dem Bohrrohr 6 und insbesondere der Spitze des Bohrrohres 6 abgewandten Seite angeordnet. Somit kann der Bohrantrieb 11 bis an die Rohrkupplung 18 an den Erdboden herangefahren werden.For storing filling material, a tube bunker 30 is provided above the drill pipe 6 in extension of its longitudinal axis. This tube bunker 30 has a cylindrical storage area 33 for receiving filling material, to which a conical outlet area 34 adjoins on the bottom side. The tube bunker 30 is above the drill drive 11 and the carriage 22, that is arranged on the drill pipe 6 and in particular the tip of the drill pipe 6 side facing away. Thus, the drill drive 11 can be moved up to the pipe coupling 18 to the ground.

Zum Einleiten von Füllgut aus dem Rohrbunker 30 in das Bohrrohr 6 ist unten am Auslassbereich 34 des Rohrbunkers 30 ein Verlängerungsrohr 40 angeordnet. Dieses Verlängerungsrohr 40 durchläuft das Antriebsteil 12, das Getriebeteil 13 und die als Hohlwelle ausgebildete Abtriebswelle 19 des Bohrantriebs 11 mittig und mündet in das Bohrrohr 6 ein. Das Füllgut kann somit aus dem Rohrbunker 30 durch das Verlängerungsrohr 40 und die Abtriebswelle 19 in das Bohrrohr 6 eingeleitet werden.For introducing contents from the tube bunker 30 into the drill pipe 6, an extension pipe 40 is arranged at the bottom of the outlet region 34 of the pipe bunker 30. This extension tube 40 passes through the drive part 12, the transmission part 13 and the output shaft 19 of the drill drive 11 designed as a hollow shaft in the center and opens into the drill pipe 6. The filling material can thus be introduced from the tube bunker 30 through the extension tube 40 and the output shaft 19 in the drill pipe 6.

Um eine Drehentkopplung des Rohrbunkers 30 vom Bohrrohr 6 zu ermöglichen, kann, beispielsweise am Verlängerungsrohr 40, eine Drehkupplung vorgesehen sein, die auch als Spülkopf bezeichnet werden kann.In order to enable a rotational decoupling of the tubular bunker 30 from the drill pipe 6, a rotary coupling can be provided, for example on the extension pipe 40, which can also be referred to as a rinsing head.

Der in Figur 1 dargestellte Rohrbunker 30 kann gegenüber dem Schlitten 22 und dem Bohrantrieb 11 höhenverstellbar, d.h. in der Bohrrichtung axial verstellbar am Schlitten 22 gelagert sein. Zum aktiven Verstellen kann beispielsweise das Verbindungsrohr 40 als eine Kellystange ausgebildet sein, welche Längsstege zur Drehmomentübertragung und Verriegeltaschen zum Aufbringen von Axialkräften aufweist.The in FIG. 1 Pipe bunker 30 shown can be height-adjustable relative to the carriage 22 and the drill drive 11, that is, axially displaceable on the carriage 22 in the drilling direction. For active adjustment, for example, the connecting tube 40 may be formed as a Kelly bar, which has longitudinal webs for transmitting torque and locking pockets for applying axial forces.

Ein weiteres Ausführungsbeispiel des erfindungsgemäßen Bohrgerätes ist in den Figuren 2 und 3 dargestellt. Das Ausführungsbeispiel der Figuren 2 und 3 unterscheidet sich vom Ausführungsbeispiel der Figur 1 im Wesentlichen dadurch, dass zum drehfesten Stützen und bevorzugt auch zum aktiven Höhenverstellen des Rohrbunkers 30 zwischen dem Schlitten 22 und insbesondere dem Bohrantrieb 11 einerseits und dem Rohrbunker 30 andererseits eine Stütze 50 vorgesehen ist, die in Bohrrichtung verläuft.Another embodiment of the drilling device according to the invention is in the Figures 2 and 3 shown. The embodiment of Figures 2 and 3 differs from the embodiment of FIG. 1 essentially by the fact that for support against rotation and preferably also for active height adjustment of the tubular bunker 30 between the carriage 22 and in particular the drill drive 11 on the one hand and the tubular bunker 30 on the other hand, a support 50 is provided which extends in the drilling direction.

Gemäß dem Ausführungsbeispiel der Figuren 2 und 3 ist zwischen dem Bohrrohr 6 und dem Rohrbunker 30 am Verbindungsrohr 40 eine Drehkupplung 60 angeordnet. Diese wird von einem Seitenarm der Stütze 50 gehalten. Sie sorgt für eine Drehentkopplung des Bohrrohres 6 vom Rohrbunker 30. Der Rohrbunker 30 ist dabei über die Stütze 50 drehfest bezüglich dem Bohrantrieb 11 und dem Schlitten 22 festgelegt.According to the embodiment of the Figures 2 and 3 is disposed between the drill pipe 6 and the pipe bunker 30 on the connecting pipe 40, a rotary joint 60. This is held by a side arm of the support 50. It ensures a rotational decoupling of the drill pipe 6 from the pipe bunker 30. The pipe bunker 30 is fixed in terms of rotation relative to the drill drive 11 and the carriage 22 via the support 50.

Ein weiteres Ausführungsbeispiel eines Rohrbunkers 30 zur Verwendung in einem erfindungsgemäßen Bohrgerät ist in Figur 4 dargestellt. Der Rohrbunker 30 der Figur 4 ist am oberen Ende des Speicherbereichs 33 durch einen konischen Deckel 36 verschlossen. In dem Deckel 36 sind Einfüllöffnungen 37 zum Einfüllen von Füllgut in den Speicherbereich 33 vorgesehen. Am Deckel 36 sind ferner verschiedenartige Ösen 38, 38' zum Anheben des Deckels 36 und/oder des Rohrbunkers 30 mittels eines Hilfskrans vorgesehen.Another embodiment of a tubular bunker 30 for use in a drilling rig according to the invention is shown in FIG FIG. 4 shown.
