Description

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Patentanspruchs 1 und ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 7.The invention relates to a device according to the preamble of patent claim 1 and a method according to the preamble of patent claim 7.

Hiermit werden sogenannte Bodenmörtellamellen aus dem anstehenden Boden unter Zugabe eines selbsterhärtenden Bindemittels hergestellt. Ein gattungsgemäßer Stand der Technik geht aus der DE 102 38 646 B3 hervor.Hereby so-called soil mortar lamellae are produced from the pending soil with the addition of a self-hardening binder. A generic state of the art goes out of the DE 102 38 646 B3 out.

Um im Baugrund oder Boden durchgehende, möglichst dichte Wände herzustellen, wird neben überschnittenen Bohrpfahlwänden oder Schlitzwänden auch das Mixedin-Place-Verfahren verwendet. Hierbei handelt es sich um ein wirtschaftliches Verfahren, bei dem der anstehende Boden mit einem selbsterhärtenden Bindemittel an Ort und Stelle vermischt wird, um eine Wand aus Bodenmörtel zu erhalten.In order to produce continuous, as dense walls as possible in subsoil or soil, the mixed-in-place method is used in addition to overcut bored pile walls or diaphragm walls. This is an economical process in which the adjacent soil is mixed with a self-hardening binder in place to obtain a wall of floor mortar.

Zur Herstellung dieser Wände aus Bodenmörtel werden bevorzugterweise zwei oder mehrere stangeförmige Mischwerkzeuge gleichzeitig in den Boden eingedreht. Diese Mischwerkzeuge können entweder über die gesamte Länge oder auch nur über einen Teil der Gestängelänge mit unterschiedlichsten Mischwerkzeugen ausgerüstet werden. Diese Mischwerkzeuge bestehen in der Regel aus einem Seelenrohr an dem unterschiedlichste Mischwerkzeuge in Form von Schneckenstücken, durchgehenden Schnecken, paddelartigen Flächen oder sonstigen Rührwerkzeugen angeordnet sind, welche gleichmäßig oder ungleichmäßig über die Länge des stangenförmigen Rührwerkzeuges verteilt sind. Es sind auch stangenförmige Mischwerkzeuge bekannt, bei denen die Mischeinrichtungen nur im unteren Teil der Gestänge angeordnet sind.To produce these walls of floor mortar preferably two or more rod-shaped mixing tools are simultaneously screwed into the ground. These mixing tools can be equipped either over the entire length or only over part of the boom length with a wide variety of mixing tools. These mixing tools usually consist of a core tube to which a wide variety of mixing tools in the form of screw pieces, continuous screws, paddle-like surfaces or other stirring tools are arranged, which are distributed uniformly or non-uniformly over the length of the rod-shaped stirring tool. There are also rod-shaped mixing tools are known in which the mixing devices are arranged only in the lower part of the linkage.

Beim Bodenmischverfahren mit stangenförmigen Mischwerkzeugen wird während des Eindrehens dieser Mischwerkzeuge in den gewachsenen Boden bevorzugt im unteren Bereich eine Suspension in den Boden eingepresst. Diese Suspensionen bestehen aus Wasser und einem meist selbst erhärtenden Bindemittel wie Zement. Weiter werden zur Stabilisierung der Bindemittelsuspensionen auch Bentonit oder ähnliche stabilisierende Chemikalien zugegeben. Diese können auch beschleunigende oder verzögernde Wirkung haben und die Verarbeitbarkeit des Bodenmörtels und seine Fließfähigkeit beeinflussen.In the soil mixing process with rod-shaped mixing tools, a suspension is pressed into the soil during the screwing of these mixing tools into the grown soil, preferably in the lower region. These suspensions consist of water and a usually self-hardening binder such as cement. Further, bentonite or similar stabilizing chemicals are also added to stabilize the binder suspensions. These can also have accelerating or retarding action and affect the workability of the floor mortar and its flowability.

Je nachdem, wie viele einzelne stangenförmige Mischwerkzeuge nebeneinander angeordnet sind, entstehen schmälere oder breitere Lamellen Um eine dichte Wand aus einzelnen Elementen herzustellen, ist es zweckmäßig, dass die einzelnen Lamellen sich überschneiden. Je mehr einzelne Mischwerkzeuge gleichzeitig in den Boden eingedreht werden, um so geringer ist die Anzahl der überschnittenen Fugen, was die Häufigkeit von Fehlstellen reduziert, da diese meist an den Fugen auftreten.Depending on how many individual rod-shaped mixing tools are arranged side by side, resulting in narrower or wider slats To produce a dense wall of individual elements, it is expedient that the individual slats overlap. The more individual mixing tools are screwed into the ground at the same time, the lower the number of overlapped joints, which reduces the frequency of defects, as they usually occur at the joints.

Da mit diesen stangenförmigen Mischwerkzeugen Wände mit Tiefen von mehr als 10 m hergestellt werden können, ist es ein entscheidendes Qualitätsmerkmal, dass man die räumliche Stellung der einzelnen Lamellen aus Bodenmörtel zueinander kennt.Since walls with depths of more than 10 m can be produced with these bar-shaped mixing tools, it is a decisive quality feature that one knows the spatial position of the individual slats of floor mortar to each other.

Hintergrund für die erfindungsgemäße Vorrichtung und das zugehörige Verfahren besteht darin, dass man gesicherte Aussagen darüber erhält, wie die Stellung der Mischwerkzeuge in größeren Tiefen ist.The background for the device according to the invention and the associated method is that one obtains reliable statements about how the position of the mixing tools is at greater depths.

Beim Eintauchen in den Baugrund ist diese Überschneidung noch einfach optisch festzustellen, aber da die Mischwerkzeuge mit verhältnismäßig geringen Seelenrohrdurchmessern ausgeführt werden, ist die gesamte Mischvorrichtung relativ weich und verformbar und so neigen diese Bodenmörtellamellen erfahrungsgemäß in der Tiefe zu größeren Abweichungen. Dabei können Fenster zwischen einzelnen Lamellen entstehen, durch die später Grundwasser durch die Wände strömen kann.When submerged in the ground, this overlap is still easy to determine optically, but since the mixing tools are designed with relatively small core tube diameters, the entire mixing device is relatively soft and deformable and so tend this Bodenmörtellamellen in depth to larger deviations. In this case, windows can be created between individual slats through which groundwater can later flow through the walls.

Bisher hat man die Vertikalität dieser Bodenmischwerkzeuge dadurch kontrolliert, dass man nach Erreichen der Endtiefe bei einigen Probelamellen die Antriebsmotoren abgekoppelt und die Seelenrohre mit Neigungsmessgeräten befahren hat. Diese Messung ist jedoch sehr aufwändig und kostet viel Zeit, was die Wirtschaftlichkeit des Verfahrens stark beeinflusst. Zudem ist es dann für eine Korrektur der Abweichung zu spät.So far, the verticality of these soil mixing tools has been controlled by decoupling the drive motors after reaching the final depth of some test blades and driving the soul tubes with inclination measuring devices. However, this measurement is very complicated and costs a lot of time, which is the economic efficiency heavily influenced by the process. In addition, it is then too late for a correction of the deviation.

Erschwerend beim Arbeiten mit mehreren stangenförmigen Mischwerkzeugen ist, dass die Bodenmörtellamellen nicht nur in einer schrägen Ebene verlaufen, sondern dass sich diese Lamellen auch in sich verdrehen oder tordieren, da die Verbindung der Drehachsen beziehungsweise Seelenrohre der einzelnen Bodenmischwerkzeuge untereinander nicht sehr stabil ist.To complicate when working with several rod-shaped mixing tools is that the Bodenmörtellamellen not only run in an oblique plane, but that these slats twist or twist in itself, since the connection of the axes of rotation or core tubes of the individual soil mixing tools is not very stable.

Aus der DE 199 60 036 C1 ist ein Verfahren zum Vermessen eines Bohrloches im Boden bekannt, bei dem ein Bohrloch mit einem Bohrgestänge erstellt wird. Am Fußpunkt des Bohrgestänges sowie an einem oberen Punkt sind Inklinometer zum Vermessen des Bohrloches angeordnet.From the DE 199 60 036 C1 a method is known for measuring a borehole in the ground, in which a borehole is created with a drill string. At the base of the drill string and at an upper point inclinometers are arranged to measure the borehole.

Weiterhin ist aus der DE 198 37 546 A1 eine Messvorrichtung zum Bestimmen der Ausrichtung und des Verlaufes eines Bohrgestänges bekannt. Entlang des Bohrgestänges sind mehrere Inklinometersensoren zur Durchführung der Messung angeordnet.Furthermore, from the DE 198 37 546 A1 a measuring device for determining the orientation and the course of a drill pipe known. Along the drill string several inclinometer sensors are arranged to perform the measurement.

Die Erfindung hat nun die Aufgabe, auf einfache und wirtschaftliche Weise vertikale Wände im Boden mit besonders guter Dichtheit zu erstellen.The invention now has the task of creating a simple and economical way vertical walls in the soil with particularly good tightness.

Die Aufgabe wird nach der Erfindung zum einen durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 und zum anderen durch ein Verfahren mit den Merkmalen des Anspruchs 7 gelöst. Bevorzugte Ausführungsformen sind in den jeweils abhängigen Ansprüchen angegeben.The object is achieved according to the invention on the one hand by a device having the features of claim 1 and on the other hand by a method having the features of claim 7. Preferred embodiments are given in the respective dependent claims.

An mindestens zwei der stangenförmigen Mischwerkzeuge werden jeweils mindestens zwei Neigungsmessaufnehmer in unterschiedlichen Höhen angeordnet. Sie können in zwei Richtungen die Neigung der Drehachsen der stangenförmigen Mischwerkzeuge bestimmen und zusätzlich sind an diesen Mischwerkzeugen Stellvorrichtungen vorhanden, mit denen man die Drehachsen der einzelnen Mischwerkzeuge auf einen vorgegebenen Drehwinkel einstellen kann. Somit kann man in unterschiedlichen Eintauchtiefen der einzelnen Mischwerkzeuge immer beim gleichen vorgegebenen Drehwinkel eine Neigungsmessung in zwei Richtungen zur Vertikalen ausführen.At least two inclinometers each are arranged at different heights on at least two of the bar-shaped mixing tools. You can determine the inclination of the axes of rotation of the rod-shaped mixing tools in two directions and in addition to these mixing tools adjusting devices are available with which you can set the axes of rotation of the individual mixing tools to a predetermined angle of rotation. Thus, you can always perform a tilt measurement in two directions to the vertical in different immersion depths of the individual mixing tools at the same predetermined rotation angle.

Mit diesen Neigungsmessungen in unterschiedlichen Tiefen lassen sich bereits während des Abteufens für eine Mörtellamelle zwei Polygonzuglinien ermitteln.With these inclination measurements at different depths, it is already possible to determine two traverse lines for a mortar during excavation.

Da die Drehachsen der stangenförmigen Mischwerkzeuge durch besondere Abstandhalter und Gestängeführungen zueinander gleichmäßig beabstandet sind, lässt sich über die beiden gemessenen Polygonzüge einer Mörtellamelle auf die räumliche geometrische Lage der einzelnen Lamelle schließen.Since the axes of rotation of the rod-shaped mixing tools are uniformly spaced from each other by special spacers and linkage guides, it is possible to deduce the spatial geometric position of the individual lamella via the two measured traverses of a mortar lamella.

Die Erfindung wird anhand der Figuren 1 bis 3 erläutert.The invention is based on the FIGS. 1 to 3 explained.

Fig. 1 zeigt eine erfindungsgemäße Vorrichtung zur Herstellung von Bodenmörtellamellen, wobei bei einer erfindungsgemäßen Ausführungsvariante in den äußeren Seelenrohren oder Drehachsen mindestens zwei Neigungsmessaufnehmer 4 angeordnet sind, wobei bevorzugterweise ein Neigungsmessaufnehmer möglichst weit unten im Gestänge angeordnet ist und der andere Messaufnehmer möglichst weit oben im Bereich des Schlittens 12. Fig. 1 shows a device according to the invention for the production of Bodenmörtellamellen, wherein in a variant of the invention in the outer core tubes or axes of rotation at least two Neigungsmessaufnehmer 4 are arranged, wherein preferably a Neigungsmessaufnehmer is located as far down in the linkage and the other sensor as far as possible in the top of the carriage 12th ,

In Fig. 2 ist in einer Draufsicht auf eine einzelne Mörtellamelle der Schnitt 20 durch eine Lamelle an der Geländeoberfläche und der Schnitt 30 nach Erreichen der Endtiefe dargestellt. Die Lage der Seelenrohre der stangenförmigen Mischwerkzeuge zeigen die Punkte 21 und 22 im Bereich der Geländeoberfläche und die Punkte 31 und 32 nach Erreichen der Endtiefe.In Fig. 2 is shown in a plan view of a single mortar lamella the section 20 by a lamella on the terrain surface and the section 30 after reaching the final depth. The position of the core tubes of the bar-shaped mixing tools show the points 21 and 22 in the area of the terrain surface and the points 31 and 32 after reaching the final depth.

Fig. 3 zeigt die geometrische Darstellung mit der erfindungsgemäßen Vorrichtung von zwei Bodenmörtellamellen, zwischen denen sich aufgrund eines Verlaufens der Lamelle in der Tiefe ein keilförmiger Schlitz 50 geöffnet hat, in dem kein Bodenmörtel vorhanden ist. Fig. 3 shows the geometric representation of the device according to the invention of two soil mortar lamellae, between which a wedge-shaped slot 50 has opened due to a running of the blade in the depth, in which no soil mortar is present.

Geräte, mit denen solche Bodenmörtellamellen hergestellt werden können, besitzen einen Turm 2, an dem ein Schlitten 12 auf und abfährt. Dieser Schlitten 12 kann über Zylinder oder umlaufende Ketten oder Drahtseile entlang des Turmes bewegt werden. Am Schlitten 12 sind mehrere stangenförmige Mischwerkzeuge 5 befestigt.Equipment with which such Bodenmörtellamellen can be produced, have a tower 2, on which a carriage 12 and leaves. This carriage 12 can be moved over cylinders or circulating chains or wire ropes along the tower. On slide 12 a plurality of rod-shaped mixing tools 5 are attached.

Bevorzugterweise werden in den beiden äußeren Mischwerkzeugen mehrere Neigungsmessaufnehmer 4 angeordnet. Da die einzelnen Mischwerkzeuge in der Regel Seelenrohre mit einem kleinen Querschnitt besitzen, sind diese Mischwerkzeuge insbesondere bei größeren Längen verhältnismäßig weich und können von der Vertikalen abweichen und sich leicht verbiegen. Die Mischwerkzeuge sind aus Stabilisierungsgründen im unteren Bereich mit Verbindungselementen 9 miteinander verbunden, welche die einzelnen Mischwerkzeuge auf gleichem Abstand halten.Preferably, a plurality of inclinometers 4 are arranged in the two outer mixing tools. Since the individual mixing tools usually have soul tubes with a small cross-section, these are mixing tools especially for larger lengths relatively soft and can deviate from the vertical and bend easily. For reasons of stabilization, the mixing tools are connected to one another in the lower region with connecting elements 9, which hold the individual mixing tools at the same distance.

Eine weitere Befestigung der Mischwerkzeuge am luftseitigen Ende erfolgt an einem Rahmen 11 an dem die Drehantriebe 13 und die Spülköpfe 14 für die Suspensionszuführung angeordnet sind.Further attachment of the mixing tools at the air-side end takes place on a frame 11 on which the rotary drives 13 and the rinsing heads 14 for the suspension feed are arranged.

Um eine Schrägstellung beziehungsweise Durchbiegung der Mischwerkzeuge 5 während des Eindrehens in den Boden feststellen zu können, werden erfindungsgemäß mindestens zwei Neigungsmessaufnehmer 4 im Inneren der Seelenrohre der Mischwerkzeuge angeordnet. Diese Neigungsmessaufnehmer 4 sind fest zueinander beabstandet und mit ihren Messungen lässt sich der Verlauf des Mischwerkzeuggestänges in unterschiedlichen Tiefen der Eindringung in den Boden feststellen. Zudem sind die Neigungsmessaufnehmer 4 auch drehfest mit den Mischwerkzeugen 5 verbunden.In order to be able to determine an inclination or deflection of the mixing tools 5 during the screwing into the ground, according to the invention at least two tilt measuring sensors 4 are arranged in the interior of the core tubes of the mixing tools. These inclinometers 4 are fixedly spaced from one another and their measurements allow the course of the mixing tool linkage to be determined at different depths of the penetration into the ground. In addition, the inclinometer 4 are also rotatably connected to the mixing tools 5.

Zum Einbau dieser Neigungsmessaufnehmer 4 werden diese in Messketten zusammengefasst, die in einem Zuge ins Innere der Mischwerkzeuge 5 eingeführt werden können und dann anschließend dort fixiert werden. Je mehr Neigungsmessaufnehmer 4, umso größer ist die Genauigkeit der Messung des Polygonzuges.To install these inclinometers 4, these are combined in measuring chains, which can be introduced in one go into the interior of the mixing tools 5 and then subsequently fixed there. The more inclination transducers 4, the greater the accuracy of the measurement of the traverse.

Um den Rechenaufwand bei der Bestimmung der Abweichungen zu minimieren, ist es zweckmäßig, dass die Hauptmessebenen der Neigungsmessaufnehmer beim Messvorgang in die gleiche Richtung weisen.In order to minimize the computational effort when determining the deviations, it is expedient that the main measurement planes of the inclination transducers point in the same direction during the measurement process.

Zudem ist es sinnvoll und zweckmäßig, dass auch in verschiedenen Eindringtiefen in den Boden beim Messen die Hauptmessrichtungen der Neigungsmessaufnehmer 4 im gleichen Winkel stehen.In addition, it is useful and expedient that even at different penetration depths into the ground when measuring the main measuring directions of the inclination sensors 4 are at the same angle.

Dazu hat jedes Mischwerkzeug 5 eine Stellvorrichtung, mit der ein vorgegebener Drehwinkel der Drehachse der Mischwerkzeuge 5 eingestellt werden kann. Sind die Mischwerkzeuge 5 über ein Getriebe drehversatzfrei miteinander verbunden, so reicht eine Stellvorrichtung.For this purpose, each mixing tool 5 has an adjusting device with which a predetermined angle of rotation of the axis of rotation of the mixing tools 5 can be set can. If the mixing tools 5 are connected to each other in a rotationally offset-free manner via a gear, then an adjusting device is sufficient.

Über diese Stellvorrichtung ist es möglich, dass der Fahrer bei jeder Eindringtiefe der Mischwerkzeuge 5 bei einem gleichen vorgegebenen Drehwinkel der Drehachse bzw. in der gleichen Richtung die Messung ausführen kann.About this adjusting device, it is possible that the driver at each penetration depth of the mixing tools 5 at a same predetermined rotation angle of the rotation axis or in the same direction can perform the measurement.

Auf diese Weise lässt sich über die zwei beabstandeten Polygonzüge eine räumliche Lage und gegebenenfalls Verbiegung oder Verdrehung der Einzellamellen feststellen, welche durch die nebeneinander angeordneten Mischwerkzeuge 5 gebildet wird.In this way, a spatial position and possibly bending or twisting of the individual lamellae, which is formed by the juxtaposed mixing tools 5, can be detected via the two spaced-apart polygons.

Bevorzugterweise wird der vorgegebene Drehwinkel so gewählt, dass wenigstens eine der Hauptmessebenen der Neigungsaufnehmer 4 in der geplanten Wandrichtung der herzustellenden Wand verläuft.Preferably, the predetermined rotation angle is selected so that at least one of the main measurement planes of the inclination sensor 4 extends in the planned wall direction of the wall to be produced.

Wählt man einen anderen Drehwinkel, so sind zusätzliche Umrechnungen erforderlich.If you choose a different angle of rotation, additional conversions are required.

Als Neigungsmessaufnehmer können prinzipiell alle Neigungsmessaufnehmer nach dem Stand der Technik verwendet werden.In principle, all inclinometers according to the prior art can be used as inclinometers.

Bei diesen Neigungsmessaufnehmern handelt es sich entweder um Pendel, welche den Winkel der Drehachsen zur Vertikalen oder Horizontalen bestimmen.These inclinometers are either pendulums, which determine the angle of the axes of rotation to the vertical or horizontal.

Bei einem anderen Messprinzip wird die Neigung der Achse zu einem sich selbst nivellierenden Flüssigkeitsspiegel bestimmt.In another measuring principle, the inclination of the axis is determined to a self-leveling liquid level.

Zur Einstellung des vorgegebenen Drehwinkels der Mischwerkzeuge 5 für die einzelnen Messungen werden Stellvorrichtungen nach dem Stand der Technik verwendet.To set the predetermined angle of rotation of the mixing tools 5 for the individual measurements actuators are used in the prior art.

Eine bevorzugte Ausführung zur Einstellung des vorgegebenen Drehwinkels besteht aus einem oder mehreren Näherungsschaltern und den dazugehörigen Kontaktgebern. Bevorzugterweise befinden sich die Näherungsschalter an nicht drehenden Stellen des Schlittens oder Bereichen des Drehantriebes oder Bereichen des Drehgestänges oder Seelenrohres der Mischwerkzeuge.A preferred embodiment for setting the predetermined angle of rotation consists of one or more proximity switches and the associated contactors. Preferably, the proximity switches are located at non-rotating points of the carriage or portions of the rotary drive or portions of the rotary linkage or core tube of the mixing tools.

Die Kontaktgeber sind direkt oder indirekt an den drehenden Teilen der Mischwerkzeuge 5 befestigt.The contactors are attached directly or indirectly to the rotating parts of the mixing tools 5.

Bevorzugterweise sind sie am Seelenrohr befestigt oder an Flanschen, Scheiben oder Zahnrädern, welche fest mit der Drehachse beziehungsweise dem Seelenrohr verbunden sind.Preferably, they are attached to the core tube or flanges, discs or gears, which are fixedly connected to the axis of rotation or the tube of the soul.

Erreicht der Kontaktgeber oder Kontakt den Näherungsschalter, so kann entweder der Drehantrieb automatisch beim vorgegebenen Drehwinkel angehalten werden oder das Anhalten erfolgt über ein Signal, das der Nährungsschalter gibt und aufgrund dessen der Fahrer den Drehantrieb anhält. Die Signale können optisch oder akustisch sein.If the contactor or contact reaches the proximity switch, either the rotary drive can be automatically stopped at the predetermined angle of rotation, or the stopping takes place via a signal given by the proximity switch and as a result of which the driver stops the rotary drive. The signals can be optical or acoustic.

Um den vorgegebenen Stellwinkel möglichst genau anfahren zu können, kann es zweckmäßig sein, dass der gewünschte Stellwinkel über mehrere einzelne Näherungsschalter, welche nebeneinander oder nacheinander angeordnet sind, angefahren wird. Auf diese Weise kann das Drehgestänge zur Messung stufenweise abgebremst werden und der vorgegebene Drehwinkel genauer und schneller angefahren werden.In order to approach the predetermined setting angle as accurately as possible, it may be appropriate for the desired setting angle to be approached via a plurality of individual proximity switches, which are arranged side by side or one after the other. In this way, the rotary linkage for measuring can be slowed down gradually and the predetermined rotation angle can be approached more accurately and faster.

Die Stellvorrichtung kann auch aus mechanischen oder elektronischen Drehwinkelgebern nach dem Stand der Technik bestehen. Diese zeigen durch direkte oder indirekte Messung die Drehstellung der Drehachse des Mischwerkzeuges an.The adjusting device can also consist of mechanical or electronic rotary encoders according to the prior art. These indicate by direct or indirect measurement, the rotational position of the axis of rotation of the mixing tool.

In einer weiteren Ausführungsform wird die Drehstellung der Achse der Mischwerkzeuge 5 über kompassartige Vorrichtungen ermittelt, angezeigt und angefahren.In a further embodiment, the rotational position of the axis of the mixing tools 5 is determined via compass-like devices, displayed and approached.

Die entsprechenden Neigungsmessungen in unterschiedlichen Tiefenlagen werden bevorzugterweise bei stehendem Mischwerkzeug durchgeführt.The corresponding inclination measurements in different depth positions are preferably carried out while the mixing tool is stationary.

Nach der Messung wird dem Gerätefahrer die Lage und Verformung der gerade hergestellten Einzellamelle auf dem Bildschirm angezeigt.After the measurement, the device driver is shown the position and deformation of the single lamella just produced on the screen.

In Fig. 2 und Fig. 3 sind erfindungsgemäße Ausführungsbeispiele für die Anzeige des Messergebnisses auf dem Bildschirm des Gerätefahrers dargestellt. In Fig. 2 wird beispielsweise die Lage 20 einer Bodenmörtellamelle als Horizontalschnitt auf Höhe der Geländeroberkante dargestellt. Die Lage 30 stellt den Horizontalschnitt durch die hergestellte Bodenmörtellamelle dar, wie sie sich aus der Berechnung der Neigung an der tiefsten Stelle der Lamelle ergibt. Die Vorrichtung hat im Beispiel 3 Mischwerkzeuge.In Fig. 2 and Fig. 3 embodiments of the invention for the display of the measurement result on the screen of the device driver are shown. In Fig. 2 For example, the layer 20 of a Bodenmörtellamelle is shown as a horizontal section at the level of the upper railing. The layer 30 represents the horizontal section through the prepared Bodenmörtellamelle, as they are calculated from the calculation of the inclination at the lowest point of the lamella. The device has in Example 3 mixing tools.

Die Lage der Mittelpunkte der Drehachse mit den Neigungsmessaufnehmern wird durch die Punkte 31 und 32 wiedergegeben.The position of the centers of the axis of rotation with the inclination transducers is represented by the points 31 and 32.

In einer anderen erfindungsgemäßen Darstellung kann auf dem Anzeigebildschirm im Fahrerhaus auch die Solllage 33 der herzustellenden Wand dargestellt werden.In another illustration according to the invention, the desired position 33 of the wall to be produced can also be displayed on the display screen in the driver's cab.

Durch Anordnung mehrerer Messintervalle in unterschiedlichen Tiefen ist es dem Gerätefahrer möglich, beim Abteufen der Vorrichtung die Vertikalität des Schlitzes nachzukorrigieren.By arranging several measuring intervals at different depths, it is possible for the device driver to correct the verticality of the slot when the device is lowered.

In Fig. 3 wird einer der besonderen Vorteile der erfindungsgemäßen Vorrichtung gezeigt.In Fig. 3 one of the particular advantages of the device according to the invention is shown.

Hier ist der Verlauf von zwei Lamellen dargestellt, welche sich an der Geländeoberfläche noch wie gewünscht, ausreichend überschneiden. Bei größerer Tiefe weichen diese Elemente jedoch in entgegengesetzte Richtungen voneinander ab und es entsteht in größerer Tiefe eine Lücke 50.Here, the course of two lamellae is shown, which still overlap sufficiently on the terrain surface as desired. At greater depth, however, these elements deviate from each other in opposite directions and a gap 50 is created at a greater depth.

Zur Verhinderung größerer Durchlässigkeiten an dieser Stelle kann der Gerätefahrer in diesem Fall eine weitere Einzellamelle zwischen die beiden hergestellten Lamellen setzen.To prevent larger permeabilities at this point, the device operator can set in this case another single lamella between the two blades produced.

Um die Neigungsmessaufnehmer 4 mit Strom zu versorgen und um die Messsignale abzugreifen, sind bevorzugterweise schleifringartige Datenübertragungssysteme an den Drehachsen bzw. dem Drehantrieb angeordnet.In order to supply the inclinometers 4 with current and to pick up the measuring signals, slip-ring-type data transmission systems are preferably arranged on the axes of rotation or the rotary drive.

Die Übertragung kann über Berührung oder mit berührungsfreien Übertragungstechniken erfolgen. Eine Funkübertragung ist ebenso möglich.Transmission may be via touch or non-contact transmission techniques. A radio transmission is also possible.

Das Anhalten der Drehgetriebe bei bestimmten vorgegebenen Drehwinkeln kann automatisch über eine Steuerung oder von Hand durch den Gerätefahrer erfolgen. Im Handbetrieb wird dem Fahrer die Annäherung oder das Erreichen des vorgegebenen Drehwinkels optisch oder akustisch angezeigt. Bevorzugterweise wird vor der Ablesung die Drehgeschwindigkeit der stangenförmigen Mischwerkzeuge 5 herabgesetzt oder ganz gestoppt.The stopping of the rotary gear at certain predetermined angles of rotation can be done automatically by a controller or manually by the device driver. In manual mode, the driver is visually or acoustically displayed the approach or reaching the predetermined rotation angle. Preferably, before the reading, the rotational speed of the rod-shaped mixing tools 5 is reduced or stopped completely.

Die optische Anzeige der erreichten oder gewünschten Drehstellung der Mischwerkzeuge 5 im Fahrerhaus erfolgt über Lämpchen, Zeiger, Balken oder sonstige Anzeigemittel oder Symbole nach dem Stand der Bildschirmtechnik oder Anzeigetechnik.The optical display of the achieved or desired rotational position of the mixing tools 5 in the cab via lights, pointers, bars or other display means or symbols according to the state of the screen technology or display technology.
