Description

Gebiet der ErfindungField of the invention

Die vorliegende Erfindung betrifft eine Vorrichtung sowie ein Verfahren zum Vermessen von Düsenstrahlsäulen im Untergrund, die für ein Bohr- und Düsgestänge zur Erzeugung eines Bohrlochs wie einer Düsenstrahlsäule im Bereich des Bohrlochs geeignet ist.The present invention relates to an apparatus and a method for measuring underground jet columns which are suitable for a drilling and nozzle linkage for producing a borehole such as a jet column in the region of the borehole.

Stand der TechnikState of the art

Das Verfahren zum Herstellen von Düsenstrahlsäulen ist ein Verfahren des Spezialtiefbaus, bei dem ein energiereicher Hochdruckstrahl aus Wasser und/oder Bindemittel aus einem sich drehenden Bohr- und Düsgestänge austritt, und dadurch der umliegende Boden hinsichtlich seiner Lagerungsstruktur zerstört und durch Zugabe von Bindemittel vermörtelt wird. In diesem Zusammenhang ist es gewünscht, die Qualität der Düsenstrahlsäulen und somit auch das Arbeitsergebnis zu überwachen. Hierfür besteht die Möglichkeit, während der Bearbeitung eine Messeinrichtung vorzusehen, beispielsweise am Bohr- und Düsgestänge.The method of producing jet columns is a special civil engineering process in which a high-energy, high-pressure jet of water and / or binder leaks out of a rotating drilling and nozzle string, thereby destroying the surrounding soil with respect to its storage structure and mortaring it by adding binder. In this context, it is desired to monitor the quality of the jet columns and thus also the work result. For this purpose, it is possible to provide a measuring device during processing, for example, on the drill and nozzle linkage.

Ein bekanntes Bohr- und Düsgestänge mit einer Messeinrichtung wird in der europäischen Patentanmeldung EP 1 974 122 A1 offenbart. Die bekannte Vorrichtung umfasst dabei ein Bohr-und Düsgestänge zur Erzeugung eines Bohrlochs sowie einer Düsenstrahlsäule im Bereich des Bohrlochs, und eine Messvorrichtung zum Vermessen der Düsenstrahlsäule, wobei diese Messvorrichtung zumindest teilweise in das Bohr- und Düsgestänge integriert ist. Mit einer solchen Vorrichtung ist es möglich, während des Betriebs des Bohr- und Düsgestänges die Qualität der Düsenstrahlsäulen flexibel und zuverlässig zu überwachen.A well-known drilling and nozzle linkage with a measuring device is in the European patent application EP 1 974 122 A1 disclosed. The known device comprises a drilling and nozzle linkage for producing a borehole and a jet column in the area of the borehole, and a measuring device for measuring the jet column, this measuring device being at least partially integrated into the drilling and nozzle linkage. With such a device is it is possible to flexibly and reliably monitor the quality of the jet columns during the operation of the drilling and nozzle boom.

Darstellung der ErfindungPresentation of the invention

Es ist Aufgabe der vorliegenden Erfindung, eine Messeinrichtung zur Beurteilung einer Düsenstrahlsäule bereitzustellen, die gegenüber dem Stand der Technik leichter handhabbar ist und insbesondere einen geringeren Platzbedarf erfordert.It is an object of the present invention to provide a measuring device for the assessment of a jet column, which is easier to handle compared to the prior art and in particular requires less space.

Diese Aufgabe wird durch den Gegenstand von Anspruch 1 gelöst. Weitere beispielhafte Ausführungsformen sind den abhängigen Ansprüchen zu entnehmen.This object is solved by the subject matter of claim 1. Further exemplary embodiments can be found in the dependent claims.

Kerngedanke der vorliegenden Erfindung ist es, ein mit einem Sensor versehenes Tastelement mit den für den geforderten Einsatz bevorzugten Eigenschaften auszustatten und in vorteilhafter Weise im Bohr- und Düsgestänge aufzunehmen und zu führen.The core idea of the present invention is to equip a probe element provided with a sensor with the properties preferred for the required application and to advantageously receive and guide it in the drill and nozzle linkage.

Gemäß Anspruch 1 wird eine Messeinrichtung für ein Bohr- und Düsgestänge bereitgestellt. Das Bohr- und Düsgestänge ist zur Erzeugung eines Bohrlochs und einer Düsenstrahlsäule im Bereich des Bohrlochs eingerichtet. Dies bedeutet, dass mit dem Bohr- und Düsgestänge zuerst ein Bohrloch in einem Untergrund/Erdreich eingebracht wird, und in einer geeigneten Tiefe das Erdreich aufgeweicht wird (Düsenstrahlsäule).According to claim 1, a measuring device for a drilling and nozzle linkage is provided. The drilling and nozzle linkage is set up to create a borehole and a jet column in the area of the borehole. This means that with the drilling and nozzle linkage first a borehole is placed in a substrate / soil, and at a suitable depth the soil is softened (nozzle jet column).

Die erfindungsgemäße Messeinrichtung ist unter anderem zum Vermessen dieser Düsenstrahlsäule eingerichtet, insbesondere zum Vermessen des Durchmessers der Düsenstrahlsäule, und die Messeinrichtung ist in das Bohr- und Düsgestänge integriert. Ferner weist die Messeinrichtung ein bevorzugt mit einem Sensor versehenes Tastelement auf, das von einer eingefahrenen Position zu einer ausgefahrenen Position bewegbar ist, welches Tastelement innerhalb der Messeinrichtung zu einem an der Messeinrichtung angebrachten Ein- und Ausfahrgehäuse umgelenkt wird. Erfindungsgemäß besteht das Tastelement zumindest abschnittsweise aus einer Formgedächtnislegierung. Bevorzugt handelt es sich um eine Metalllegierung aus Nickel-Titan. Eine Variante dieser Metalllegierung ist unter dem Namen Nitinol bekannt. Derartige Materialien weisen überraschenderweise auch für den Einsatz im Bereich des Tiefbaus/Spezialtiefbaus vorteilhafte Eigenschaften auf. Dabei ist das Tastelement für eine Umlenkung flexibel, hält jedoch außerhalb der Messeinrichtung, also innerhalb der Düsenstrahlsäule, den äußeren Gegebenheiten stand und kann somit den Sensor für eine Messung in der Düsenstrahlsäule führen.The measuring device according to the invention is, inter alia, adapted for measuring this jet jet column, in particular for measuring the diameter of the jet jet column, and the measuring device is integrated in the drilling and nozzle rod. Furthermore, the measuring device has a preferably provided with a sensor probe element, which from a retracted position to an extended position is movable, which probe element is deflected within the measuring device to a mounted on the measuring device input and Ausfahrgehäuse. According to the invention, the probe element consists at least in sections of a shape memory alloy. It is preferably a metal alloy of nickel-titanium. A variant of this metal alloy is known under the name Nitinol. Surprisingly, such materials also have advantageous properties for use in civil engineering / special civil engineering. In this case, the probe element for a deflection is flexible, but outside the measuring device, ie within the nozzle jet column, the external conditions stood and thus can lead the sensor for a measurement in the jet column.

Bei einer weiteren Ausführungsform ist das Tastelement um einen Winkel von im Wesentlichen 90° umlenkbar. Dies hat den Vorteil, dass das Tastelement innerhalb des Bohr- und Düsgestänges geführt, und seitlich aus dem Bohr- und Düsgestänge ausgebracht werden kann.In a further embodiment, the probe element is deflectable by an angle of substantially 90 °. This has the advantage that the probe element can be guided within the drilling and nozzle linkage, and can be discharged laterally out of the drilling and nozzle linkage.

Falls das Tastelement mit dem bereits erwähnten Sensor versehen ist, könnte es sich bei diesem Sensor um einen Druck- und/oder Neigungssensor handeln. Ferner kann mit einem solchen Sensor der Durchmesser der Düsenstrahlsäule ermittelt werden, wobei der Neigungssensor eine gültige Messung sicherstellen kann. Besonders bevorzugt kann es demnach sein, dass der Sensor mehrere kombinierte Einzelsensoren aufweist. Allerdings ist es bei einer alternativen Zielrichtung denkbar, dass mit dem Tastelement und einer weiteren Vorrichtung eine Messung zum Erfassen der Düsenstrahlsäule durchgeführt wird. Insbesondere kann beim Ausfahren des Tastelements durch Überwachen der Motorleistung festgestellt werden, wann das Tastelement die Wandung der Düsenstrahlsäule erreicht hat: Nimmt der Stromverbrauch des Motors zu und wird gleichzeitig eine Vergrößerung der ausgefahrenen Länge des Tastelements nicht festgestellt, dann hat das Tastelement die Wandung der Düsenstrahlsäule erreicht.If the probe element is provided with the aforementioned sensor, this sensor could be a pressure and / or tilt sensor. Furthermore, with such a sensor, the diameter of the jet column can be determined, wherein the tilt sensor can ensure a valid measurement. It may therefore be particularly preferred for the sensor to have a plurality of combined individual sensors. However, in an alternative embodiment, it is conceivable that a measurement is carried out for detecting the jet column with the probe element and a further device. In particular, when the probe element is extended by monitoring the engine power, it can be ascertained when the probe element has reached the wall of the nozzle jet column: If the power consumption of the motor increases and at the same time an increase in the extended length of the motor is reached Detected probe element, then the probe element has reached the wall of the jet column.

Die beschriebenen Maßnahmen zur Erfassung und Bewertung der Düsenstrahlsäule können auch in Kombination miteinander zum Einsatz kommen.The measures described for the detection and evaluation of the nozzle jet column can also be used in combination with each other.

Ist das Tastelement mit dem Sensor versehen, so wird dieser im Betrieb der erfindungsgemäßen Messeinrichtung durch die Öffnung des Ein- und Ausfahrgehäuses, das an der Messeinrichtung angebracht ist, ein- und ausgefahren. In einer Ausführungsform ist der Sensor dabei derart ausgelegt, unter anderem dimensioniert, dass er die Öffnung des Ein- und Ausfahrgehäuses im eingefahrenen Zustand abdichtet.If the probe element is provided with the sensor, then this is in the operation of the measuring device according to the invention by the opening of the retraction and extension housing, which is attached to the measuring device, retracted and extended. In one embodiment, the sensor is designed such that, inter alia, dimensioned such that it seals the opening of the retraction and retraction in the retracted state.

Bei einer weiteren bevorzugten Messeinrichtung sind innerhalb dieser Rollen vorgesehen, mit denen das Tastelement umgelenkt wird. Die Rollen stellen eine sichere und wenig fehleranfällige Umlenkung bereit, wobei das Tastelement bei der Förderung über die Rollen äußerlich nicht wesentlich verändert wird (also beispielsweise nicht verformt wird).In a further preferred measuring device are provided within these roles, with which the probe element is deflected. The roles provide a safe and less error-prone diversion, the probe element is not significantly changed externally in the promotion of the roles (ie, for example, is not deformed).

In einer weiteren Ausführungsform ist das Tastelement gegenüber dem Bohr- und Düsgestänge abgedichtet. Jedoch wird das Tastelement innerhalb des Bohr- und Düsgestänges vor Schmutz und Verunreinigungen, die beim Verfahren eine Reibung bedingen können, geschützt.In a further embodiment, the probe element is sealed off from the drilling and nozzle linkage. However, the probe element within the drilling and nozzle linkage is protected from dirt and contaminants, which can cause friction in the process.

Insbesondere kann beim Ein- und Ausfahrgehäuse ein Spülkanal vorgesehen sein, durch den das Tastelement beim Ein- und Ausfahren mit Wasser oder einer Suspension gespült wird. Dies erleichtert den Abdichtvorgang und stellt sicher, dass keine Verunreinigungen in das Bohr- und Düsgestänge gelangen.In particular, a flushing channel can be provided in the retraction and extension housing, through which the probe element is flushed during retraction and extension with water or a suspension. This facilitates the sealing process and ensures that no contaminants get into the drilling and nozzle linkage.

Bei einer weiteren Variante der Messeinrichtung ist innerhalb dieser eine Antriebsvorrichtung vorgesehen, mit der das Tastelement angetrieben werden kann. Die Krafteinleitung erfolgt hierbei bevorzugt im Bereich der Umlenkung des Tastelements. Hierdurch wird ein sicheres Ein- und Ausfahren des Tastelements in und aus der Messeinrichtung gewährleistet.In a further variant of the measuring device a drive device is provided within this, with which the probe element can be driven. The force application takes place here preferably in the region of the deflection of the probe element. This ensures a safe retraction and extension of the probe element in and out of the measuring device.

Ferner ist es bevorzugt, dass das Tastelement vor seiner Umlenkung vorgekrümmt wird. Die Vorkrümmung kann hier beispielsweise mit der ersten Rolle im Bereich der Umlenkung vorgesehen werden. Hierdurch wird das Tastelement nicht direkt in die Richtung umgelenkt, die zum Austrittspunkt des Tastelements aus der Messeinrichtung führt, sondern bevorzugt entgegen dieser Richtung. Dies erleichtert die Bewegung des Tastelements, und es kann unter Umständen ein größerer Umlenkradius innerhalb der Messeinrichtung realisiert werden, nachdem das Tastelement weiter zur Wand der Messeinrichtung vorgekrümmt wird. Auch führt diese Vorkrümmung zu einer Stabilisierung des Tastelements.Furthermore, it is preferred that the feeler element is pre-curved prior to its deflection. The pre-curvature can be provided here, for example, with the first roller in the area of the deflection. As a result, the probe element is not deflected directly in the direction leading to the exit point of the probe element from the measuring device, but preferably against this direction. This facilitates the movement of the probe element, and it may be possible to realize a larger deflection radius within the measuring device after the probe element is further precessed to the wall of the measuring device. Also, this Vorkrümmung leads to a stabilization of the probe element.

Als bevorzugtes Material für das Tastelement wird eine Nickel-Titan-Legierung verwendet, beispielsweise eine unter dem Namen Nitinol bekannte Legierung. Diese zeichnet sich in besonderer Weise für die geforderten Eigenschaften für das Tastelement aus.As a preferred material for the probe element, a nickel-titanium alloy is used, for example, an alloy known under the name Nitinol. This is characterized in a special way for the required properties for the probe element.

Ferner betrifft die vorliegende Erfindung ein Bohr- und Düsgestänge zur Erzeugung eines Bohrlochs, wobei dieses Bohr-und Düsgestänge eine Düseneinrichtung und eine hieran angebrachte Messeinrichtung nach einer der zuvor genannten Varianten aufweist. Ferner kann an der Messeinrichtung eine Bohrkrone angebracht sein, insbesondere über einen zwischen diesen angebrachten Adapter. Mit der genannten Bohrkrone wird ein Bohrloch erzeugt, und die Düseneinrichtung wird zur Ausbildung einer Düsenstrahlsäule verwendet.Furthermore, the present invention relates to a drilling and nozzle linkage for producing a borehole, said drilling and nozzle linkage having a nozzle device and a measuring device attached thereto according to one of the aforementioned variants.

Dieses setzt sich hierbei aus verschiedenen Abschnitten zusammen, nämlich einem Anschlussabschnitt 11, einem Zwischenabschnitt 12, einer Düseneinrichtung 13, einer Messeinrichtung 14, eines Adapters 15 sowie einer Bohrkrone 16. Diese Elemente sind in der entsprechenden Reihenfolge angeordnet, und jeweils mittels Gewinden verbunden. In Figur 3 sind die Gewinde 7, 8, 9 und 10 zwischen dem Abschnitt 12, der Düseneinrichtung 13, der Messeinrichtung 14, dem Adapter 15 sowie der Bohrkrone 16 im Detail dargestellt. FIG. 2 This is composed of various sections, namely a connection section 11, an intermediate section 12, a nozzle device 13, a measuring device 14, an adapter 15 and a drill bit 16. These elements are in the corresponding Order arranged, and each connected by threads. In FIG. 3 the threads 7, 8, 9 and 10 between the section 12, the nozzle device 13, the measuring device 14, the adapter 15 and the drill bit 16 are shown in detail.

Zum Bohr- und Düsgestänge 1 wird eine Hochdrucksuspensionsleitung 3 für die Hochdrucksuspension, eine Leitung 4 für Luft sowie eine Leitung 5 für den Bohrspüler zugeführt.For drilling and nozzle linkage 1, a high-pressure suspension line 3 for the high-pressure suspension, a line 4 for air and a line 5 for the drilling fluid is supplied.

Am Anschluss der Leitung 3 für die Hochdrucksuspension ist eine Lagerung/Dichtung 100 vorgesehen. An einem Aufsatz 101 zur Leitung 4 ist ebenfalls eine Lagerung/Dichtung 102 sowie eine weitere Lagerung/Dichtung 103 angebracht. Die Leitung 5 für den Bohrspüler ist mit einem 2-Zoll Schlauchanschluss 105 an einem Aufsatz 104 angebracht. Ferner ist zwischen dem Aufsatz 104 und dem Bohr- und Düsgestänge 1, insbesondere dem Abschnitt 11, eine Lagerung/Dichtung 106 vorgesehen.At the connection of the line 3 for the high-pressure suspension, a bearing / seal 100 is provided. On a top 101 to line 4 is also a bearing / seal 102 and another bearing / seal 103 is attached. The pipe 5 for the drill is attached to a top 104 with a 2 inch hose connector 105. Furthermore, a bearing / seal 106 is provided between the attachment 104 and the drilling and nozzle linkage 1, in particular the section 11.

In Figur 2 ist ein Teil der am Abschnitt 12 angebrachten Düseneinrichtung 13 sowie der Messeinrichtung 14 im Detail dargestellt. Die Düseneinrichtung 13 sowie die Messeinrichtung 14 sind in dieser Ausführungsform durch eine Schraubverbindung 8 aneinander lösbar gekoppelt.In FIG. 2 is a part of the mounted on section 12 nozzle device 13 and the measuring device 14 shown in detail. In this embodiment, the nozzle device 13 and the measuring device 14 are detachably coupled to one another by a screw connection 8.

Dabei ist die Düseneinrichtung 13 für ein Aufbringen einer Hochdrucksuspension unter Hochdruck eingerichtet, die durch eine Hochdrucksuspensionsleitung 3 zugeführt wird. Als Arbeitsfluid für die Unterstützung der Hochdrucksuspension ist vorzugsweise Luft vorgesehen, die durch eine weitere Leitung 4 zugeführt wird.In this case, the nozzle device 13 is adapted for applying a high-pressure suspension under high pressure, which is supplied through a high-pressure suspension line 3. As the working fluid for the support of the high-pressure suspension, air is preferably provided, which is supplied through a further line 4.

Im vorliegenden Ausführungsbeispiel sind Schraubverbindungen 7-10 vorgesehen. Dichtungsringe stellen sicher, dass keine Verunreinigungen im Betrieb beispielsweise in die Messeinrichtung 14 gelangen. Alternativ zu den Schraubverbindungen 7-10 können jedoch auch einzelne, radial angreifende Schrauben vorgesehen sein, mit denen beispielsweise die Messeinrichtung 14 an der Düseneinrichtung 13 angeschraubt wird. Auch andere Steckverbindungen sind denkbar.In the present embodiment, screw 7-10 are provided. Sealing rings ensure that no impurities enter the measuring device 14 during operation, for example. As an alternative to the screw connections 7-10, however, it is also possible to provide individual radially engaging screws with which, for example, the measuring device 14 is screwed to the nozzle device 13. Other plug connections are conceivable.

In der Messeinrichtung 14 wird ein stab- oder kabelförmiges Tastelement 40 mit einem Sensor 40a geführt, dessen Hülle in der vorliegenden Ausführungsform aus einer Nickel-Titan-Legierung besteht. Diese Nickel-Titan-Legierung gehört zur Gruppe der Formgedächtnislegierungen (Shape-Memory) und ist auch unter dem Namen Nitinol bekannt. Üblicherweise werden derartige Materialen im Bereich der Medizintechnik eingesetzt. Allerdings wurde im Rahmen der vorliegend durchgeführten Entwicklungsarbeiten herausgefunden, dass sich Nitinol überraschenderweise auch für Vorrichtungen einsetzen lässt, die im Bereich des Tiefbaus oder Spezialtiefbaus verwendet werden.In the measuring device 14, a rod-shaped or cable-shaped feeler element 40 is guided with a sensor 40a, the shell of which in the present embodiment consists of a nickel-titanium alloy. This nickel-titanium alloy belongs to the group of shape memory alloys (Shape Memory) and is also known under the name Nitinol. Usually, such materials are used in the field of medical technology. However, in the context of the development work carried out in the present case, it has surprisingly been found that nitinol can also be used for devices used in civil engineering or special civil engineering.

Das Tastelement 40 wird parallel zur Hochdrucksuspensionsleitung 3 geführt und in die Messeinrichtung 14 eingebracht. Hierzu ist in einem zur Düseneinrichtung 13 weisenden Bereich der Messeinrichtung 14 ein Motor 41 vorgesehen, mit dem das Tastelement 40 angetrieben werden kann. Die Antriebskraft wird über eine Antriebsrolle 41a auf das Tastelement 41a übertragen.The feeler element 40 is guided parallel to the high-pressure suspension line 3 and introduced into the measuring device 14. For this purpose, a motor 41 is provided in a pointing to the nozzle device 13 region of the measuring device 14, with which the probe element 40 can be driven. The driving force is transmitted to the feeler 41a via a drive roller 41a.

Ferner wird das Tastelements 40 im Bereich der Messeinrichtung von einer vertikalen Richtung in eine horizontale Richtung umgelenkt. Als "vertikal" wird im Sinne der vorliegenden Anmeldung eine Richtung entlang des Bohr-und Düsgestänges 1 verstanden, wohingegen eine "horizontale" Richtung senkrecht zu dieser ausgerichtet ist.Further, the probe element 40 is deflected in the region of the measuring device from a vertical direction in a horizontal direction. For the purposes of the present application, "vertical" is understood to mean a direction along the drilling and nozzle linkage 1, whereas a "horizontal" direction is oriented perpendicular thereto.

Es sind mehrere Rollen 42 innerhalb der Messeinrichtung 14 derart vorgesehen, dass das Tastelement 40 gegenüber der zum Hochdrucksuspensionskanal 3 parallelen Führung im Wesentlichen um einen Winkel von 90° geführt wird. In diesem Zusammenhang ist Figur 2 zu entnehmen, dass vor der Umlenkung des Tastelements 40 eine sogenannte Vorkrümmung vorgenommen wird, und zwar vor der in Zuführrichtung ersten Rolle 42. Auf diese Weise kann die in Vorschubrichtung später erfolgende Umlenkung des Tastelements 40 um einen Winkel von 90° in der Messeinrichtung besser eingestellt werden.There are a plurality of rollers 42 provided within the measuring device 14 such that the probe element 40 is guided relative to the parallel to the high pressure suspension channel 3 guide substantially at an angle of 90 °. In this context is FIG. 2 can be seen that prior to the deflection of the probe element 40, a so-called pre-curvature is made, in front of the feed in the first roller 42. In this way, the deflection later in the feed direction of the probe element 40 by an angle of 90 ° in the measuring device set better become.

Nachdem das Tastelement 40 innerhalb der Messeinrichtung 14 von einer vertikalen Richtung (Verlauf innerhalb der Düseneinrichtung 13) in eine im Wesentlichen horizontale Richtung gebracht ist, erstreckt sich das Tastelement 40 durch ein Ein- und Ausfahrgehäuse 43. Das Ein- und Ausfahrgehäuse 43 weist ein Dichtelement 44 auf, mit dem das Innere der Messeinrichtung 14 gegenüber der Außenseite abgedichtet wird.After the feeler element 40 is brought into a substantially horizontal direction within the measuring device 14 from a vertical direction (course within the nozzle device 13), the feeler element 40 extends through an extension and retraction housing 43. The retraction and extension housing 43 has a sealing element 44, with which the interior of the measuring device 14 is sealed from the outside.

Ferner ist das Sensorelement 40a, das an einem Ende des Tastelements 40 angebracht ist, derart ausgebildet, dass es sich an die Öffnung im Ein- und Ausfahrgehäuse 43 anlegen kann und dadurch alternativ oder zusätzlich zum Dichtelement 44 eine Abdichtung gegenüber dem Inneren der Messeinrichtung 14 bereitstellt.Furthermore, the sensor element 40a, which is attached to one end of the feeler element 40, is designed such that it can rest against the opening in the retraction and extension housing 43, thereby providing a seal against the interior of the measurement device 14 as an alternative or in addition to the seal element 44 ,

Die Bewegung des Tastelements 40 wird in der vorliegenden Ausführungsform im Bereich der Umlenkung des Tastelements 40 mittels des Motors 41 eingeleitet. Gegebenenfalls können alternativ oder zusätzlich hierzu auch einzelne Rollen 42 angetrieben werden. Darüber hinaus können im Bereich des Bohr- und Düsgestänges weitere integrierte Motoren vorgesehen sein. Die genannten Antriebe werden beispielsweise über den Batteriebetrieb der Messsysteme angeregt.The movement of the probe element 40 in the present embodiment in the region of the deflection of the probe element 40th initiated by the motor 41. Optionally, as an alternative or in addition to this, individual rollers 42 can also be driven. In addition, further integrated motors can be provided in the area of the drilling and nozzle linkage. The drives mentioned are excited, for example, via the battery operation of the measuring systems.

Zur Messung wird das Tastelement 40 von der Dichteinrichtung 44 wegbewegt, und zwar tritt in horizontaler Richtung, und wird in die noch nicht ausgehärtete Düsenstrahlsäule eingeführt. Beispielsweise kann das Tastelement 40 bis zu 2m aus der Dichteinrichtung ausgefahren werden. Durch die Eigensteifigkeit des Tastelements 40 und den Auftrieb auf den abgedichteten Stab ist es möglich, dieses auch außerhalb der Messeinrichtung 14 in einer im Wesentlichen horizontalen Richtung zu halten.For measurement, the probe element 40 is moved away from the sealing device 44, namely occurs in the horizontal direction, and is introduced into the not yet cured nozzle jet column. For example, the probe element 40 can be extended up to 2m from the sealing device. Due to the inherent rigidity of the probe element 40 and the buoyancy on the sealed rod, it is possible to keep this outside the measuring device 14 in a substantially horizontal direction.

Die Initialisierung des Messvorgangs mit Hilfe des Tastelements erfolgt durch Körperschallimpulse, die in das Bohr- und Düsgestänge 1 eingeleitet werden, oder durch Funkübertragung. Die Schritte zum Vermessen einer Düsenstrahlsäule in einem Untergrund können dann wie folgt verlaufen. In einem ersten Schritt wird ein geeigneter Bohransatzpunkt vermessen. In einem weiteren Arbeitsschritt wird das Bohr- und Düsgestänge 1 an dem neuen Bohransatzpunkt eingebracht, und anschließend das Bohr- und Düsgestänge 1 mittels Abbohren auf eine gewünschte Tiefe abgesenkt, wobei bohrbegleitend der Bohrlochverlauf durch die eingebauten Neigungssensoren gemessen werden.The initialization of the measurement process by means of the probe element is effected by structure-borne sound pulses, which are introduced into the drilling and nozzle linkage 1, or by radio transmission. The steps for measuring a jet column in a subsurface may then proceed as follows. In a first step, a suitable drill point is measured. In a further step, the drilling and nozzle linkage 1 is introduced at the new Bohransatzpunkt, and then lowered the drilling and nozzle linkage 1 by means of drilling to a desired depth, whereby borehole course are measured by the built-in inclination sensors during drilling.

Nach Erreichen der gewünschten Bohrtiefe wird eine Düsenstrahlsäule im Bereich des Bohrlochs erzeugt, und der Durchmesser der erzeugten Düsenstrahlsäule wird auf verschiedenen Höhen gemessen. So wird das Tastelement 40 in der noch nicht ausgehärteten Düsenstrahlsäule bewegt. Das Tastelement 40 ist dabei vorteilhafterweise so ausgelegt, dass es Aufgrund des Antriebs, der Eigensteifigkeit, des Eigengewichts und des Auftriebs im Wesentlichen horizontal gehalten werden kann. Die durch das Tastelement 40 erfassten und gespeicherten Daten können parallel zur Messung oder auch zeitversetzt beim Hochziehen des Bohr- und Düsgestänges aus dem Bohrloch ausgelesen werden. Anhand dieser Daten sind konkrete Aussagen über die Beschaffenheit des Bodens sowie die davon abhängige Beschaffenheit der erzeugten Düsenstrahlsäule möglich. Diese Ergebnisse können für weitere Berechnungen genutzt werden.After reaching the desired drilling depth, a nozzle jet column is created in the area of the borehole, and the diameter of the generated jet column is measured at different heights. Thus, the probe element 40 is moved in the not yet cured jet column. The probe element 40 is advantageously designed so that it due to the drive, the inherent rigidity of the Dead weight and buoyancy can be kept substantially horizontal. The data acquired and stored by the feeler element 40 can be read out of the borehole in parallel with the measurement or also with a time delay when pulling up the drill and nozzle linkage. On the basis of these data, concrete statements about the condition of the soil as well as the dependent condition of the produced jet column are possible. These results can be used for further calculations.

Wurde die Messung durchgeführt, wird das Tastelement 40 beim Einfahren in die Messeinrichtung 14 über den am Ein- und Ausfahrgehäuse 43 vorgesehenen Spülkanal 44 mit Wasserdruck abgespült und während des Einfahrens gegenüber dem flüssigen Medium im Bohrloch und der Säule abgedichtet. Die Wasserspülung vor dem Ein- und Ausfahrgehäuse 43 erleichtert somit den Abdichtvorgang und stellt sicher, dass keine Verunreinigungen ins Innere der Messeinrichtung 14 gelangen.Was the measurement performed, the sensing element 40 is rinsed when entering the measuring device 14 via the provided on the retraction and housing 43 flushing channel 44 with water pressure and sealed during retraction against the liquid medium in the borehole and the column. The water flushing in front of the retraction and extension housing 43 thus facilitates the sealing process and ensures that no impurities enter the interior of the measuring device 14.

Die Bohrkrone 12 kann beispielsweise direkt an der Messeinrichtung 14 angeschlossen werden. Alternativ kann wie in der vorliegenden Ausführungsform gezeigt zwischen der Messeinrichtung 14 und der Bohrkrone 12 ein Adapter 15 vorgesehen sein. Anstelle eines Adapters 15 können auch mehrere Elemente zwischen der Messeinrichtung 14 der Bohrkrone 12 vorgesehen sein.The drill bit 12 can for example be connected directly to the measuring device 14. Alternatively, as shown in the present embodiment, an adapter 15 may be provided between the measuring device 14 and the drill bit 12. Instead of an adapter 15, a plurality of elements between the measuring device 14 of the drill bit 12 may be provided.

Die Bohrkrone 12 weist Öffnungen 26 für einen Bohrspüler auf. Aus diesen Öffnungen 26 tritt eine Flüssigkeit aus der Bohrkrone aus und ermöglicht somit das Eindringen der Bohr-und Düsgestänges 1 in den Untergrund/ das Erdreich.The drill bit 12 has openings 26 for a drilling fluid. From these openings 26 emerges a liquid from the drill bit and thus allows the penetration of the drilling and nozzle rod 1 in the ground / the soil.
