Abstract

After a rock anchor (1), in particular an expandable friction tube anchor (1), comprising an anchor bolt (2) has been inserted into a pre-sunk borehole with an end sleeve (4) first, an adapter (6) having a liquid inflow and outflow is arranged on a sleeve (3). On the one hand, a holding pressure which secures the adapter (6) to the sleeve (3) is produced via a holding-pressure line (8). On the other hand, fluid flows into the anchor bolt (2) via an expansion line (7) and starts to fill said bolt. In the process, the increase in pressure (inflation pressure) causes the anchor bolt (2) to expand in the borehole, with the result that its outer surface presses against the borehole wall and thus secures the rock anchor (1) in the borehole. A gas supply connected to the adapter (6) makes it possible for a gas under pressure, in particular compressed air, to be introduced into the anchor bolt (2) before and/or after the expansion thereof. The compressed gas is relieved following the removal of the adapter (6) (pressure equalization) and conveys the fluid contained in the anchor bolt (2) virtually completely from the anchor (1).

Description

Fluidrückgewinnung Fluid recovery
Die Erfindung betrifft eine Vorrichtung zum Aufweiten und/oder Entleeren von Teilen von Ankern, insbesondere von Gebirgs- ankern der Gattung Reibrohranker oder aufweitbarer Reibrohranker, mit den Merkmalen des Oberbegriffes von Anspruch 1.The invention relates to a device for expanding and / or emptying parts of anchors, in particular of mountain anchors of the type Reibrohranker or expandable Reibrohranker, with the features of the preamble of claim 1.
Des Weiteren betrifft die Erfindung ein Verfahren zum Entleeren von Teilen von Ankern, insbesondere von Gebirgsankern der Gattung Reibrohranker oder aufweitbarer Reibrohranker, mit den Merkma- len des Oberbegriffes von Anspruch 8.Furthermore, the invention relates to a method for emptying parts of anchors, in particular of rock anchors of the type Reibrohranker or expandable Reibrohranker, with the features of the preamble of claim 8.
Darüber hinaus betrifft die Erfindung ein Verfahren zum Setzen von Ankern, insbesondere von Gebirgsankern der Gattung Reibrohranker oder aufweitbarer Reibrohranker, mit den Merkmalen des Oberbegriffes von Anspruch 16. Es ist bekannt Anker mit aufweitbaren Teilen zum Festigen bzw. Sichern von Gestein und Boden, beispielsweise beim Tunnelbau oder zur HangSicherung, in ein Bohrloch einzusetzen. Solche Anker, insbesondere Reibrohranker bzw. aufweitbare Reibrohranker, sind unter der Bezeichnung "Swellex" (Hersteller Atlas Copco MAI GmbH) bekannt.. Als aufweitbare Teile weisen diese Anker insbesondere aufweitbare Ankerbolzen auf, deren Außenfläche im aufgeweiteten Zustand an die Bohrlochwand anliegt und den Anker so im Bohrloch festlegt. Das Aufweiten der Bolzen kann mit Wasser erfolgen, das mittels einer Pumpe über einen abnehmbaren Adapter mit Druck in den Ankerbolzen eingebracht wird.Moreover, the invention relates to a method for setting anchors, in particular rock anchors of the type Reibrohranker or expandable Reibrohranker, with the features of the preamble of claim 16. It is known anchor with expandable parts for strengthening or securing of rock and soil, for example Tunneling or to HangSicherung to use in a borehole. Such anchors, in particular friction tube anchors or expandable friction tube anchors, are known under the name "Swellex" (manufacturer Atlas Copco MAI GmbH). As expandable parts, these anchors have, in particular, expandable anchor bolts, the outer surface of which rests against the borehole wall in the widened state and the armature so sets down in the hole. The expansion of the bolt can be done with water, which is introduced by means of a pump via a removable adapter with pressure in the anchor bolt.
Die im Ankerbolzen nach dem Einpressen des aufzuweitenden Mediums, insbesondere von Wasser, komprimierte Luft bewirkt, dass das Wasser nach dem Abnehmen des Adapters wieder aus dem Ankerbolzen hinausgedrückt wird. Es hat sich jedoch als nachteilig herausge- stellt, dass Wasser unkontrolliert und nur teilweise wieder aus dem Ankerbolzen austritt. Ein gewisser Restanteil an Wasser verbleibt im Ankerbolzen und begünstigt zusammen mit der im Ankerbolzen enthaltenen Luft Korrosionsvorgänge, welche sich nachteilig auf die Lebensdauer des Ankers, insbesondere Reibrohrankers, auswirken. Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung sowie Verfahren der eingangs genannten Gattung zur Verfügung zu stellen, mit welchen die angesprochene Nachteile so weit wie möglich vermieden werden. Gelöst wird diese Aufgabe mit einer Vorrichtung zum Aufweiten und/oder Entleeren von Teilen von Ankern, insbesondere von Gebirgs- ankern, welche die Merkmale des Anspruches 1 aufweist.The compressed in the anchor bolt after pressing the medium to be expanded, in particular water, causing the water after removal of the adapter is pushed out of the anchor bolt again. However, it has turned out to be disadvantageous that water escapes uncontrollably and only partially back out of the anchor bolt. A certain residual amount of water remains in the anchor bolt and favors together with the air contained in the anchor bolt corrosion processes, which adversely affect the life of the armature, in particular Reibrohrankers. The invention has for its object to provide a device and method of the type mentioned are available with which the disadvantages mentioned are avoided as much as possible. This object is achieved with a device for expanding and / or emptying parts of anchors, in particular of mountain anchors, which has the features of claim 1.
Des Weiteren wird diese Aufgabe gelöst mit einem Verfahren zum Entleeren von Teilen von Ankern, insbesondere von Gebirgsankern, welches die Merkmale des Anspruches 8 aufweist.Furthermore, this object is achieved with a method for emptying parts of anchors, in particular of rock anchors, which has the features of claim 8.
Darüber hinaus wird diese Aufgabe gelöst mit einem Verfahren zum Setzen eines Ankers, insbesondere Gebirgsankers , welches die Merkmale des Anspruches 16 aufweist. Bevorzugte und vorteilhafte Ausgestaltungen/Ausführungsformen der erfindungsgemäßen Vorrichtung einerseits sowie der erfindungsgemäßen Verfahren andererseits sind Gegenstand der Unteransprüche.In addition, this object is achieved with a method for setting an anchor, in particular rock anchor, which has the features of claim 16. Preferred and advantageous embodiments / embodiments of the device according to the invention on the one hand and the method according to the invention on the other hand are the subject of the dependent claims.
Bei Ankern, insbesondere bei als aufweitbare Reibrohranker ausgeführten Gebirgsankern, mit aufweitbaren Teilen (Anker des Typs "Swellex") und einem abnehmbar am Anker angeordneten Adapter, der sowohl über wenigstens eine Fluidleitung mit einer Pumpe als auch mit den aufweitbaren Teilen verbunden ist, ist der Adapter erfindungsgemäß mittelbar oder unmittelbar mit einer Gaszufuhr verbunden. Somit können den aufweitbaren Teilen, nachdem sie aufgeweitet (ex- pandiert) worden sind und die wenigstens zum Teil mit Fluid befüllt sind, zum Entleeren Gas unter Druck zugeführt werden. Das Gas expandiert in den aufgeweiteten Teilen und drückt das Fluid zwangsweise aus dem Anker hinaus. Dieser Vorgang kann gegebenenfalls so oft wiederholt werden, bis das Fluid vollständig entfernt ist. Die durch ein Zusammenwirken von Luft und Wasser stattfindenden Korrosionsvorgänge im Ankerbolzen können somit nahezu vollständig unterbunden werden, womit die Lebensdauer des Ankers signifikant erhöht wird.In anchors, in particular designed as expandable Reibrohranker rock anchors, with expandable parts (anchor of the type "Swellex") and a detachably mounted on the anchor adapter, which is connected via at least one fluid line with a pump as well as with the expandable parts, is the Adapter according to the invention indirectly or directly connected to a gas supply. Thus, after being expanded (expanded) and at least partially filled with fluid, the expandable portions may be supplied with gas under pressure to discharge. The gas expands in the flared portions forcing the fluid forcibly out of the anchor. If necessary, this process can be repeated until the fluid is completely removed. The corrosion processes taking place in the anchor bolt due to the interaction of air and water can thus be almost completely prevented, thus significantly increasing the life of the armature.
Erfindungsgemäß kann das Einbringen von unter Druck stehendem Gas, insbesondere von Druckluft, sowohl vor als auch nach dem Beauf- schlagen des Ankers mit dem aufweitenden Fluid erfolgen. Als Effekt bleibt bei dem künstlich erzeugten Überdruck vor der Beaufschlagung mit Fluid im Gegensatz zu bekannten Methoden, bei denen nur das unter normalen Luftdruck im Anker befindliche Luftvolumen komprimiert wird, nach dem Druckausgleich wesentlich weniger Restwasser im Anker zurück. Das in die aufweitbaren Teile eingebrachte Fluid kann nach dem Aufweiten nahezu vollständig und kontrolliert abgezogen und gegebenenfalls wieder zum Aufweiten von Teilen anderer Anker verwendet werden.According to the invention, the introduction of pressurized gas, in particular of compressed air, can take place both before and after the impact of the armature with the expanding fluid. As an effect remains in the artificially generated pressure before the application of fluid in contrast to known methods in which only the air under normal pressure in the anchor air volume is compressed, after the pressure equalization significantly less residual water in the anchor back. The introduced into the expandable parts fluid can be withdrawn almost completely and controlled after expansion and optionally used again for widening parts of other anchors.
Weitere Einzelheiten, Merkmale und Vorteile der erfindungs- gemäßen Vorrichtung einerseits sowie der erfindungsgemäßen Verfahren andererseits ergeben sich aus der nachstehenden Beschreibung unter Bezugnahme auf die angeschlossenen Zeichnungen, in welchen eine bevorzugte Ausführungsform dargestellt ist.Further details, features and advantages of the inventive device on the one hand and the inventive method On the other hand, it will become apparent from the following description with reference to the accompanying drawings in which a preferred embodiment is shown.
Es zeigt: Fig. 1 eine schematische Längsansicht einer Aus- führungsform eines Gebirgsankers, Fig. 2 eine Querschnittsansicht des Gebirgsankers aus Fig. 1, Fig. 3 den Gebirgsanker aus Fig. 1 mit einem aufgesetzten Adapter und Fig. 4 eine Ausführungsfom der erfindungsgemäßen Vorrichtung zum Aufweiten und/oder Entleeren von Teilen des Gebirgsankers in schematischer Darstellung. In Fig. 1 ist ein Gebirgsanker 1 dargestellt, bei dem die erfindungsgemäße Vorrichtung sowie das erfindungsgemäße Verfahren angewendet werden kann. Die gezeigte Ausführungsform entspricht einem aufweitbaren Reibrohranker, wie er beispielsweise aus der US 4,459,067 A bekannt ist und auch als "Swellex" bezeichnet wird. Der Gebirgsanker 1 ist dazu vorgesehen, zum Festigen bzw. Sichern von Gestein und Boden in ein Bohrloch eingesetzt und darin festgelegt zu werden.1 shows a schematic longitudinal view of an embodiment of a rock bolt, FIG. 2 shows a cross-sectional view of the rock bolt of FIG. 1, FIG. 3 shows the rock bolt of FIG. 1 with an attached adapter and FIG. 4 shows an embodiment of the device according to the invention for expanding and / or emptying parts of the rock anchor in a schematic representation. In Fig. 1, a rock anchor 1 is shown, in which the device according to the invention and the inventive method can be applied. The embodiment shown corresponds to an expandable Reibrohranker, as it is known for example from US 4,459,067 A and is also referred to as "Swellex". The rock anchor 1 is intended to be used for securing and securing rock and soil in a borehole and to be fixed therein.
Im Wesentlichen umfasst der Gebirgsanker 1 einen aufweitbaren Teil, der an einem Ende, das dem äußeren Ende des Bohrlochs benach- bart ist (in Fig 1 rechts) , eine Hülse 3 aufweist und am anderen Ende durch eine Ξndhülse 4 geschlossen ist. Der aufweitbare Teil kann insbesondere ein Ankerbolzen 2 sein, der, wie in Fig. 2 ersichtlich, durch ein in Längsrichtung nach innen gefaltetes Rohr mit einem im Wesentlichen omega-förmigen Profil gebildet ist. Der Anker- bolzen 2 kann durch Erhöhen des Druckes im Inneren des gefalteten Rohres aufgeweitet werden, sodass sich die Außenfläche des Rohres an die Bohrlochwandung anlegt und den Gebirgsanker 1 so im Bohrloch festlegt.Essentially, the rock anchor 1 comprises an expandable part which has a sleeve 3 at one end adjacent to the outer end of the borehole (right in FIG. 1) and is closed at the other end by an end sleeve 4. The expandable part may in particular be an anchor bolt 2, which, as can be seen in FIG. 2, is formed by a pipe folded in the longitudinal direction with a substantially omega-shaped profile. The anchor bolt 2 can be widened by increasing the pressure inside the folded tube, so that the outer surface of the tube rests against the borehole wall and thus fixes the rock bolt 1 in the borehole.
In der Hülse 3 ist eine Öffnung, z.B. eine Bohrung 5, angeord- net, deren Funktion im Weiteren noch beschrieben wird.In the sleeve 3 is an opening, e.g. a hole 5, arranged whose function will be described below.
Im Rahmen der Erfindung ist es selbstverständlich auch möglich, dass statt dem beschriebenen Reibrohranker andere Arten und Ausführungsformen von Ankern, vornehmlich die der eingangs genannten Gattung, herangezogen werden können. Als Beispiel soll eine Aus- führungsform genannt werden, die als "Swellex Hybrid" (HerstellerIn the context of the invention, it is of course also possible that instead of the described Reibrohranker other types and embodiments of anchors, especially those of the aforementioned type, can be used. As an example, an embodiment should be mentioned which is called "Swellex Hybrid" (manufacturer
Atlas Copco MAI GmbH) bekannt ist. Dieser Gebirgsanker zeichnet sich dadurch aus, dass mehrere Abschnitte von starren Ankerstangen/- rohren über Kuppelglieder miteinder verbunden sind, und dass an demAtlas Copco MAI GmbH) is known. This rock anchor is characterized by the fact that several sections of rigid anchor rods / - pipes are connected via coupling elements miteinder, and that on the
(vorderen) Ende der so gebildeten Ankerstange, das ins Bohrloch eingesetzt wird, lediglich ein kurzer Abschnitt eines aufweitbaren Teils, wie ein oben beschriebener Ankerbolzen 2, angeordnet ist.(front) end of the anchor rod so formed, which is inserted into the well, only a short section of an expandable Part, as an anchor bolt 2 described above, is arranged.
Der Gebirgsanker 1 kann an seinem an der Öffnung des Bohrlochs liegenden Ende eine Ankerplatte tragen, die sich Boden- oder Gestein-seitig an der Hülse 3 abstutzt. Nachdem der Gebirgsanker 1 mit angebrachter Ankerplatte in das Bohrloch eingesetzt wurde, wird an der Hülse 3, wie in Fig. 3 ersichtlich, ein Adapter 6 angeordnet. In einer bevorzugten Ausfuhrungsform wird der Adapter 6 als Inflationsadapter auf die Hülse 3 aufgesteckt bzw. aufgeschraubt. Der Adapter 6 ist über eine Fluid- leitung, insbesondere eine Expansionsleitung 7, und über eine Fluid- leitung, insbesondere eine Haltedruckleitung 8, mit einer Pumpe 9 verbunden. Zum Erhohen des Druckes im Inneren des Ankerbolzens 2 stellt die Pumpe einen Fluidarbeitsdruck (Inflationsdruck) von vorzugsweise 100 bis 500 bar, insbesondere von 240 bis 300 bar, zur Verfugung.The rock anchor 1 may carry at its lying at the opening of the borehole end an anchor plate which is supported on the ground or rock side of the sleeve 3. After the rock anchor 1 with attached anchor plate has been inserted into the borehole, an adapter 6 is arranged on the sleeve 3, as can be seen in FIG. In a preferred embodiment, the adapter 6 is plugged or screwed onto the sleeve 3 as an inflation adapter. The adapter 6 is connected to a pump 9 via a fluid line, in particular an expansion line 7, and via a fluid line, in particular a holding pressure line 8. To increase the pressure inside the anchor bolt 2, the pump provides a fluid working pressure (inflation pressure) of preferably 100 to 500 bar, in particular 240 to 300 bar, at your disposal.
Das Fluid aus der Haltedruckleitung 8 presst im Inneren des Adapters 6 zwei Dichtringe 10 so zusammen (Haltedruck) , das die entstehenden Ausbauchungen der Dichtringe 10 gegen die Hülse 3 drucken und diesen fest und gegen den Inflationsdruck dicht um- schließen. Anschließend strömt Fluid aus der Expansionsleitung 7 über eine Zulaufbohrung 11 zur Bohrung 5, die sich im abgedichteten Raum zwischen den biden Dichtringen 10 befindet, tritt in den Ankerbolzen 2 ein und beginnt diesen zu füllen. Dabei wird das Omega- Profil des Ankerbolzens 2 entfaltet, sodass sich die Außenfläche des Ankerbolzens 2 an die Bohrlochwand anlegt und den Gebirgsanker 1 so im Bohrloch festlegt. Das Ankerbolzenprofil erreicht bei fertiger Entfaltung, bei dem Fluidarbeitsdruck von ca. 240 bis 300 bar, einen annähernd runden Querschnitt.The fluid from the holding pressure line 8 presses together inside the adapter 6 two sealing rings 10 together (holding pressure), which print the resulting bulges of the sealing rings 10 against the sleeve 3 and tightly close it and against the inflation pressure. Subsequently, fluid flows from the expansion line 7 via an inlet bore 11 to the bore 5, which is located in the sealed space between the two sealing rings 10, enters the anchor bolt 2 and begins to fill it. In this case, the omega profile of the anchor bolt 2 is unfolded, so that the outer surface of the anchor bolt 2 rests against the borehole wall and the rock anchor 1 so determined in the hole. The anchor bolt profile reaches a nearly round cross-section at final deployment, at the fluid working pressure of about 240 to 300 bar.
Da das Bohrloch in der Praxis einen kleineren Durchmesser aufweist als ein vollständig aufgeweiteter Ankerbolzen 2, kann sich dieser nicht vollständig entfalten, so dass er sich unter Beibehaltung einer Längsfalte gegen die Bohrlochwandung presst. Der Vorteil der ausgebildeten Längsfalte ist, dass sie durch die entstehende Versteifung stabilitatssteigernd wirkt. Durch Beibehaltung des Arbeitsdruckes über einen Zeitraum von wenigstens sechs Sekunden presst sich der Ankerbolzen 2 auch in Unregelmäßigkeiten der Bohrlochwandung und bildet eine reib- und formschlussige Verbindung im Bohrloch.Since the borehole in practice has a smaller diameter than a fully expanded anchor bolt 2, this can not fully unfold, so that it presses while maintaining a longitudinal fold against the borehole wall. The advantage of the formed longitudinal fold is that it has a stabilizing effect due to the resulting stiffening. By maintaining the working pressure for a period of at least six seconds, the anchor bolt 2 also presses in irregularities of the borehole wall and forms a friction and formschlussige connection in the borehole.
Fig. 4 zeigt, wie der Adapter 6 über die Expansionsleitung 7 und die Haltedruckleitung 8 mit der Pumpe 9 verbunden ist. Die Pumpe 9 ist wiederum mit einer Fluidversorgungsleitung 12 verbunden. In der Expansionsleitung 7 ist ein Ventil 13 angeordnet, über welches der Zu- bzw. Abfluss von Fluid in den bzw. aus dem Adapter 6 geregelt wird. Darüber hinaus ist erfindungsgemäß vorgesehen, dass der Adapter 6 mit einer Gaszufuhr verbunden ist, die im gezeigten Ausführungsbeispiel durch eine weitere Fluidleitung, insbesondere eine Gasleitung 14, und einem Kompressor 15 gebildet ist. Der Kompressor 15 kann ein Luftkompressor sein oder mit einem Behälter mit komprimier- ter Luft verbunden sein. In der gezeigten Ausführungsform mündet die Gasleitung 14 ausgehend vom Kompressor 15 nicht direkt in den Adapter 6, sondern endet in der Expansionleitung 7 im Bereich zwischen dem Adapter 6 und dem Ventil 13. In der Gasleitung 14 ist ein Ventil 16 angeordnet, über welches der Gasdurchlass geregelt wird. Die Ventile 13, 16, sowie die Pumpe 9 und der Kompressor 15 werden über eine Steuereinheit 17 gesteuert.Fig. 4 shows how the adapter 6 is connected via the expansion line 7 and the holding pressure line 8 to the pump 9. The pump 9 is in turn connected to a fluid supply line 12. In the expansion line 7, a valve 13 is arranged, via which the inflow and outflow of fluid in and out of the adapter 6 is regulated. In addition, the invention provides that the adapter 6 is connected to a gas supply, which is formed in the embodiment shown by a further fluid line, in particular a gas line 14, and a compressor 15. The compressor 15 may be an air compressor or connected to a container of compressed air. In the embodiment shown, the gas line 14, starting from the compressor 15 does not open directly into the adapter 6, but ends in the expansion line 7 in the region between the adapter 6 and the valve 13. In the gas line 14, a valve 16 is arranged, via which the gas passage is regulated. The valves 13, 16, and the pump 9 and the compressor 15 are controlled by a control unit 17.
Erfindungsgemäß wirkt die beschriebene Vorrichtung als System zum Rückgewinnen des den Ankerbolzen 2 aufweitenden Mediums, insbesondere als Wasserrückgewinnungssystem. Mittels des Kompressors 15 kann über den Adapter 6 komprimierte Luft in den Ankerbolzen 2 gepresst werden, welche beim Expandieren restlichen und unerwünschten Fluidanteil aus dem Ankerbolzen 2 in die Expansionsleitung 7 leitet. Das Einbringen von unter Druck stehendem Gas, insbesondere von Druckluft, kann im Rahmen der Erfindung vor und/oder nach dem Beaufschlagen des Ankers 1 mit Fluid erfolgen.According to the invention, the device described acts as a system for recovering the anchor bolt 2 expanding medium, in particular as a water recovery system. By means of the compressor 15, compressed air can be pressed into the anchor bolt 2 via the adapter 6, which air guides the remaining and unwanted fluid portion from the anchor bolt 2 into the expansion line 7 during expansion. The introduction of pressurized gas, in particular compressed air, can take place in the context of the invention before and / or after the application of the armature 1 with fluid.
Zum Einbringen insbesondere von Druckluft nach dem Aufweiten des Ankerbolzens 2 wird im einzelnen nach dem Aufweiten des Ankerbolzens 2 der Haltedruck, d.h. der Fluiddruck über die Haltedruckleitung 8 zum Zusammenpressen der Dichtungsringe 10, gehalten und der Inflationsdruck, d.h. der Fluidarbeitsdruck von vorzugsweise 240 bis 300 bar, abgesenkt. Zu diesem Verfahrenszeitpunkt ist das Ventil 13 in der Expansionsleitung 7 geöffnet und das Ventil 16 in der Gasleitung 14 geschlossen.For introducing in particular compressed air after the expansion of the anchor bolt 2 in detail after the expansion of the anchor bolt 2, the holding pressure, i. the fluid pressure is maintained via the holding pressure line 8 for compressing the seal rings 10, and the inflation pressure, i. the fluid working pressure of preferably 240 to 300 bar, lowered. At this process time, the valve 13 is opened in the expansion line 7 and the valve 16 in the gas line 14 is closed.
Wenn das Fluid weitestgehend aus dem Ankerbolzen 2 abgeflossen/ herausgedrückt ist, wird in einem nächsten Schritt das Ventil 13 geschlossen und das Ventil 16 geöffnet, so dass Gas, insbesondere Luft, über die Gasleitung 14 und die Expansionsleitung 7 in den Adapter 6, und damit in den Ankerbolzen 2, geleitet wird. Der Haltedruck ist zu diesem Zeitpunkt immer noch aufrecht. Im Anschluss daran wird das Ventil 16 wieder geschlossen und - Q - das Ventil 13 geöffnet, so dass das in den Ankerbolzen 2 hineingedrückte Gas über die Expansionsleitung 7 austritt und dabei das restliche Fluid aus dem Ankerbolzen 2 hinausdrückt.If the fluid is largely drained / pushed out of the anchor bolt 2, in a next step, the valve 13 is closed and the valve 16 is opened so that gas, in particular air, via the gas line 14 and the expansion line 7 in the adapter 6, and thus in the anchor bolt 2, is passed. The holding pressure is still upright at this time. Following this, the valve 16 is closed again and - Q - the valve 13 is opened, so that the gas pushed into the anchor bolt 2 gas exits through the expansion line 7 and thereby pushes the remaining fluid from the anchor bolt 2.
Die beschriebenen Vorgänge können gegebenenfalls so oft wie- derholt werden, bis das Fluid (z.B. Wasser) vollständig entfernt ist. Zum Abnehmen des Adapters 6 von der Hülse 3 wird der Haltedruck gesenkt.The operations described may optionally be repeated until the fluid (e.g., water) is completely removed. To remove the adapter 6 from the sleeve 3, the holding pressure is lowered.
Analog zu den bisherigen Ausführungen, insbesondere zu den beschriebenen Ventilstellungen bei der Gas- und Fluidzufuhr in den Ankerbolzen 2, besteht erfindungsgemäß auch die Möglichkeit, dass insbesondere Druckluft bereits vor dem Aufweiten des Ankerbolzens 2 in den zunächst noch leeren Anker 1, der in das Bohrloch eingeschoben wurde, eingebracht werden kann.Analogous to the previous embodiments, in particular to the valve positions described in the gas and fluid supply in the anchor bolt 2, there is also the possibility according to the invention that in particular compressed air before the expansion of the anchor bolt 2 in the initially empty anchor 1, in the borehole was inserted, can be introduced.
Anschließend wird der Anker 1 mit aufweitendem Fluid beauf- schlagt und durch Druck aufgeweitet. Das Profil entfaltet sich und der Anker 1 legt sich unter Bildung einer reib- und formschlüssigen Verbindung an die Bohrlochwand an. Während dieses Vorgangs wird die zuvor eingepreßte Luft komprimiert. Nach dem Aufweiten des Ankerbolzens 2 wird der Adapter 6 entfernt. Die komprimierte Luft entspannt sich (Druckausgleich) und leitet das im Ankerbolzen 2 befindliche Fluid aus dem Anker 1 heraus.Subsequently, the armature 1 is acted upon by expanding fluid and expanded by pressure. The profile unfolds and the anchor 1 settles to form a frictional and positive connection to the borehole wall. During this process, the previously compressed air is compressed. After the expansion of the anchor bolt 2, the adapter 6 is removed. The compressed air expands (pressure equalization) and passes the fluid located in the anchor bolt 2 out of the armature 1.
Im Gegensatz zu Methoden, bei denen das unter normalem Luftdruck im Anker 1 befindliche Luftvolumen komprimiert wird, bleibt bei dem willkürlich erzeugten Überdruck vor der Beaufschlagung mit Fluid nach dem Druckausgleich wesentlich weniger Restwasser im Anker 1 zurück. Das Innere des Ankers 1 ist dann nahezu trocken.In contrast to methods in which the air volume under anchorage 1 is compressed under normal atmospheric pressure, substantially less residual water remains in the armature 1 in the case of the arbitrarily generated overpressure before the application of fluid after pressure equalization. The interior of the anchor 1 is then almost dry.
Das aus dem Ankerbolzen 2 austretende Fluid kann von der Pumpe 9 entweder über eine Ablaufleitung 18 in einen Behälter geleitet oder direkt in einem geschlossenen Kreislauf geführt werden. Zusammenfassend kann ein Ausführungsbeispiel zum Setzen eines Gebirgsankers 1 unter Einsatz der erfindungsgemäßen Vorrichtung und des erfindungsgemäßen Verfahrens wie folgt beschrieben werden:The emerging from the anchor bolt 2 fluid can be passed from the pump 9 either via a drain line 18 in a container or performed directly in a closed circuit. In summary, an embodiment for setting a rock anchor 1 using the device according to the invention and the method according to the invention can be described as follows:
Nachdem ein einen Ankerbolzen 2 umfassender Gebirgsanker 1, insbesondere ein aufweitbarer Reibrohranker 1, mit einer Endhülse 4 voran in ein vorher erzeugtes Bohrloch eingesetzt wurde, wird an einer Hülse 3 ein Adapter 6 mit Flüssigkeitszu- bzw. -ablauf angeordnet. Zum einen wird über eine Haltedruckleitung 8 ein Haltedruck erzeugt, der den Adapter 6 an der Hülse 3 festlegt. Zum anderen strömt über eine Expansionsleitung 7 Fluid in den Ankerbolzen 2 ein und beginnt diesen zu füllen. Dabei wird der Ankerbolzen 2 aufgrund der Druckerhöhung (Inflationsdruck) im Bohrloch aufgeweitet, sodass sich dessen Außenfläche an die Bohrlochwand anlegt und den Gebirgsanker 1 so im Bohrloch festlegt.After an anchor bolt 2 comprehensive rock anchor 1, in particular an expandable Reibrohranker 1 was used with a ferrule 4 in advance in a previously produced wellbore, an adapter 6 is arranged with Flüssigkeitszu- or -ablauf on a sleeve. On the one hand, a holding pressure is generated via a holding pressure line 8, which fixes the adapter 6 on the sleeve 3. On the other hand, fluid flows into the anchor bolt 2 via an expansion line 7 and begins to fill it. In this case, the anchor bolt 2 due to the pressure increase (inflation pressure) widened in the borehole, so that its outer surface rests against the borehole wall and thus fixes the rock anchor 1 in the borehole.
Über eine mit dem Adapter 6 verbundene Gaszufuhr kann unter Druck stehendes Gas, insbesondere Druckluft, vor und/oder nach dem Aufweiten des Ankerbolzens 2 in diesen eingebracht werden. Das komprimierte Gas entspannt sich nach dem Entfernen des Adapters 6 (Druckausgleich) und leitet das im Ankerbolzen 2 befindliche Fluid nahezu vollständig aus dem Anker 1 heraus. Via a gas supply connected to the adapter 6, pressurized gas, in particular compressed air, can be introduced before and / or after the armature bolt 2 has been widened. The compressed gas expands after the removal of the adapter 6 (pressure equalization) and directs the fluid located in the anchor bolt 2 almost completely out of the armature 1.
