Description

Die Erfindung betrifft eine Vorrichtung zur Entnahme einer Probe einer Füllung, mit welcher ein Loch, insbesondere ein Bohrloch oder ein Frässchlitz, im Boden gefüllt ist. Des Weiteren betrifft die Erfindung ein Verfahren zur Entnahme einer entsprechenden Probe.The invention relates to a device for taking a sample of a filling, with which a hole, in particular a borehole or a Frässchlitz, is filled in the ground. Furthermore, the invention relates to a method for taking a corresponding sample.

Die erfindungsgemäße Vorrichtung und das erfindungsgemäße Verfahren können insbesondere bei der Erstellung von Schlitz- oder Dichtwänden oder von Mörtelsäulen im Boden Anwendung finden, die durch Verfüllung eines Bohrloches oder Schlitzes im Boden erstellt werden. Hierbei ist es häufig erwünscht, Informationen über das entsprechende auszuhärtende Medium in bestimmten Tiefen des Schlitzes oder Bohrloches zu erhalten, um eine ordnungsgemäße Bauqualität sicherzustellen. Beispielsweise kann durch eine entsprechende Probenentnahme festgestellt werden, ob die Mörtelzusammensetzung in einer bestimmten Tiefe einer vorgegebenen Zusammensetzung entspricht, die eine zuverlässige Aushärtung sicherstellt.The device according to the invention and the method according to the invention can be used in particular in the creation of slot or sealing walls or mortar columns in the ground, which are created by filling a borehole or slot in the ground. In doing so, it is often desirable to obtain information about the appropriate medium to be cured at certain depths of the slot or wellbore to ensure proper build quality. For example, it can be determined by a corresponding sampling whether the mortar composition corresponds to a certain depth of a predetermined composition, which ensures a reliable curing.

Zur Entnahme von Proben einer Bohrlochfüllung sind unterschiedliche Vorrichtungen und Verfahren bekannt.For taking samples of a well filling different devices and methods are known.

In einem bekannten Verfahren wird ein Bohrloch bis zu einer gewünschten Tiefe erstellt, das entsprechende Bohrwerkzeug aus dem Bohrloch herausgezogen, ein Stahlseil mit einer an dessen unterem Ende befestigten Stahlkugel in das mit einer Flüssigkeit oder Suspension gefüllte Bohrloch herabgelassen, eine Hülse über das Stahlseil geworfen und anschließend eine weitere Kugel ebenfalls über das Stahlseil heruntergeleitet. Dieses Verfahren ist aus DE 1 484 592 A bekannt. Durch dieses Verfahren lässt sich eine Bodenprobe zwischen den beiden Kugeln in der Hülse einschließen, die durch Herausziehen des Stahlseils aus dem Bohrloch geborgen werden kann. Für viskose Bohrlochfüllungen, wie sie beispielsweise bei der Erstellung von Mörtelsäulen oder Schlitzwänden häufig vorliegen, ist dieses Verfahren jedoch wenig geeignet.In a known method, a borehole is made to a desired depth, the corresponding drilling tool pulled out of the borehole, lowered a steel cable with a steel ball attached to the lower end in the filled with a liquid or suspension hole, a sleeve thrown over the steel cable and then another ball also led down over the steel cable. This procedure is off DE 1 484 592 A known. By this method, a soil sample can be trapped between the two balls in the sleeve, which can be recovered by pulling the steel cable out of the hole. For viscous well fillings, such as those However, in the preparation of mortar columns or diaphragm walls often present, this method is not very suitable.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zur Entnahme einer Probe einer Füllung, mit welcher ein Loch gefüllt ist, anzugeben, welche eine einfache und kostengünstige Probennahme ermöglicht und insbesondere auch für viskose Füllungen geeignet ist.The invention is therefore based on the object , a device for taking a sample of a filling, with which a hole is filled specify, which allows a simple and inexpensive sampling and in particular is also suitable for viscous fillings.

Der Erfindung liegt ferner die Aufgabe zugrunde, ein entsprechendes Verfahren zur Entnahme einer Probe zur Verfügung zu stellen.The invention is further based on the object of providing a corresponding method for taking a sample.

Die Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 und ein Verfahren mit den Merkmalen des Anspruchs 11 gelöst. Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen angegeben.The object is achieved by a device having the features of claim 1 and a method having the features of claim 11. Preferred embodiments are given in the dependent claims.

Die Vorrichtung ist erfindungsgemäß dadurch gekennzeichnet, dass ein Behälter vorgesehen ist, welcher an seiner Unterseite eine Öffnung und einen Klappboden zum Verschließen der Öffnung aufweist, wobei der Klappboden zum Öffnen in den Behälter hinein schwenkbar ist, dass an einer Oberseite des Behälters ein nach auβen zu öffnender Klappdeckel vorgesehen ist und dass der Klappboden und der Klappdeckel miteinander gekoppelt sind.The device according to the invention is characterized in that a container is provided which has on its underside an opening and a folding bottom for closing the opening, wherein the folding bottom is pivotable into the container for opening into that on an upper side of the container to the outside to opening hinged lid is provided and that the folding bottom and the hinged lid are coupled together.

Ein Grundgedanke der Erfindung kann darin gesehen werden, einen insbesondere kastenförmigen Behälter zur Probennahme vorzusehen, welcher an seiner Unterseite einen nach innen zu öffnenden Klappboden aufweist. Dabei ist insbesondere vorgesehen, dass im Wesentlichen die gesamte horizontale Bodenfläche des Behälters schwenkbar ist. Hierdurch lässt sich der Behälter bei geöffnetem Klappboden auch in eine hochviskose Füllung absenken. Durch den sich in das Innere des Behälters hineinschwenkenden Klappboden öffnet sich dieser aufgrund der vertikalen Durchströmung beim Absenken quasi selbsttätig. Durch Anheben des Behälters aus dem mit der Füllung gefüllten Loch kann sich der Klappboden automatisch aufgrund des Gewichtes der Probe in dem Behälter verschließen. Bei der Probe handelt es sich insbesondere um eine Fluidprobe, insbesondere eine Probe einer Flüssigkeit oder einer Suspension, vorzugsweise ein aushärtbares Medium.A basic idea of the invention can be seen in providing a box-shaped container, in particular, for sampling, which has on its underside an inwardly openable folding bottom. It is provided in particular that substantially the entire horizontal bottom surface of the container is pivotable. As a result, the container can also be lowered into a high-viscosity filling when the folding bottom is open. Due to the hinged into the interior of the container hinged bottom this opens quasi automatically due to the vertical flow during lowering. By lifting the container from the filled hole with the filling, the folding floor can automatically close due to the weight of the sample in the container. The sample is in particular a fluid sample, in particular a sample of a liquid or a suspension, preferably a curable medium.

Die Oberseite des Behälters weist eine zweite Öffnung und einen Klappdeckel zum Verschließen der zweiten Öffnung auf. Durch die obere Öffnung wird das Absenken des Behälters und Füllen mit der Probe erleichtert. Vorzugsweise erstreckt sich die Öffnung an der Oberseite des Behälters über im Wesentlichen den gesamten Querschnitt des Behälters.The top of the container has a second opening and a hinged lid for closing the second opening. Through the upper opening is lowering the container and filling with the sample easier. Preferably, the opening at the top of the container extends over substantially the entire cross-section of the container.

Durch die Koppelung des Klappbodens und des Klappdeckels wird eine gemeinsame Öffnungs- und Schließbewegung des Klappbodens und des Klappdeckels erzielt. Die Kopplung ist vorzugsweise so ausgeführt, dass Klappboden und Klappdeckel gleichzeitig geschlossen beziehungsweise geöffnet sind. Sobald der Boden geschlossen ist, ist also auch der Deckel geschlossen und umgekehrt.Through the coupling of the hinged floor and the hinged lid, a common opening and closing movement of the hinged floor and the hinged lid is achieved. The coupling is preferably designed so that hinged bottom and hinged lid are closed or opened at the same time. As soon as the floor is closed, so the lid is closed and vice versa.

Aufgrund der Flüssigkeitssäule oberhalb des Behälters wird der Klappdeckel beim Anheben des Behälters zuverlässig verschlossen. Damit wird automatisch auch der Klappboden verschlossen. Die Koppelung bewirkt somit ein sicheres Verschließen des Klappbodens beim Anheben des Behälters, selbst wenn das Gewicht der Probe in dem Behälter hierzu nicht ausreichen sollte. Zudem wird zuverlässig sichergestellt, dass beim Anheben des Behälters aus dem Bodenloch die eingeschlossene Füllungsprobe sicher erhalten bleibt und nicht während des Herausziehens aus dem Bodenloch durch in den Behälter eindringendes Material aus oberen Schichten verunreinigt wird.Due to the liquid column above the container, the hinged lid is reliably closed when lifting the container. This automatically closes the hinged floor. The coupling thus causes a secure closing of the hinged floor when lifting the container, even if the weight of the sample in the container should not be sufficient. In addition, it is reliably ensured that when the container is lifted out of the bottom hole, the enclosed filling sample is safely retained and is not contaminated during removal from the bottom hole by material from upper layers penetrating into the container.

Eine einfache und zugleich wirksame Kopplung kann dadurch erzielt werden, dass zur Kopplung des Klappbodens und des Klappdeckels eine sich im Inneren des Behälters erstreckende Kopplungsstange vorgesehen ist, welche einerseits an dem Klappboden und andererseits an dem Klappdeckel angelenkt ist. Die Kopplungsstange ist vorzugsweise an einer Oberseite des Klappbodens und einer Unterseite des Klappdeckels über eine Schwenkverbindung befestigt.A simple and effective coupling can be achieved in that for coupling the hinged bottom and the hinged lid extending inside the container coupling rod is provided, which is articulated on the one hand to the folding bottom and on the other hand on the hinged lid. The coupling rod is preferably attached to a top of the hinged floor and a bottom of the hinged lid via a pivotal connection.

Erfindungsgemäß ist es bevorzugt, dass die Kopplungsstange an einem Randbereich des Klappbodens, welcher einer Schwenkachse des Klappbodens gegenüberliegt, angelenkt ist. Hierdurch wird eine besonders gute Hebelwirkung beim Öffnen und Schließen des Klappbodens erzielt. Außerdem kann der Klappboden durch die entsprechend angeordnete Kopplungsstange sicher in seiner Schließstellung gehalten werden, da er an zwei gegenüberliegenden Rändern einerseits durch die Drehbeziehungsweise Schwenkachse und andererseits die Kopplungsstange gehalten wird. Hierdurch wird gegebenenfalls einem Aufbiegen des Klappbodens aufgrund des Gewichtes der Probe zuverlässig entgegengewirkt. Dies ist insbesondere dann vorteilhaft, wenn der Klappboden in der Schließstellung nicht durch ein Behältergehäuse abgestützt ist, also in der Schließstellung anschlagfrei an der Kopplungsstange hängt.According to the invention it is preferred that the coupling rod is articulated on an edge region of the hinged floor, which is opposite to a pivot axis of the hinged floor. As a result, a particularly good leverage is achieved when opening and closing the hinged floor. In addition, the folding bottom can be securely held by the correspondingly arranged coupling rod in its closed position, since it is held at two opposite edges on the one hand by the Drehbeziehungsweise pivot axis and on the other hand, the coupling rod. As a result, if necessary, a bending of the hinged floor due to the weight of the sample is reliably counteracted. This is especially true advantageous if the folding bottom is not supported by a container housing in the closed position, that is hanging in the closed position stop-free on the coupling rod.

Vorzugsweise ist die Kopplungsstange an dem Klappdeckel etwa mittig angelenkt. Der Klappdeckel, welcher vorzugsweise in der Schließstellung durch das Gehäuse des Behälters abgestützt wird, wird durch die Kopplungsstange zusätzlich zentral abgestützt, um dem Druck der Füllungssäule oberhalb des Behälters entgegenzuwirken.Preferably, the coupling rod is hinged to the hinged lid approximately centrally. The hinged lid, which is preferably supported in the closed position by the housing of the container is additionally centrally supported by the coupling rod to counteract the pressure of the filling column above the container.

Zur Verringerung des Strömungswiderstandes beim Anheben des Behälters ist es bevorzugt, dass der Klappdeckel in einer Schließstellung gegenüber einer Querschnittsfläche des Behälters geneigt ist. Der Klappdeckel ist also gegenüber einer Querschnittsfläche des Behälters beziehungsweise des erstellten Loches im Boden, welche senkrecht zu einer Längsachse des Behälters beziehungsweise des Loches verläuft, angestellt. Durch die Neigung des Klappdeckels wird die Füllung oberhalb des Behälters beim Anheben aus dem Loch seitlich abgelenkt und somit der Strömungswiderstand verringert.To reduce the flow resistance during lifting of the container, it is preferred that the hinged lid is inclined in a closed position relative to a cross-sectional area of the container. The hinged lid is thus opposite a cross-sectional area of the container or the created hole in the ground, which runs perpendicular to a longitudinal axis of the container or the hole, employed. Due to the inclination of the hinged lid, the filling is deflected laterally above the container when lifting out of the hole and thus reduces the flow resistance.

Eine gute Durchströmung des Behälters beim Absenken kann erfindungsgemäß dadurch realisiert werden, dass der Klappboden an einer ersten Seite des Behälters und der Klappdeckel an einer zweiten, gegenüberliegenden Seite des Behälters angelenkt ist. Klappboden und Klappdeckel lassen sich also in gegenüberliegende Richtungen öffnen. Der Klappboden ist in Richtung einer ersten Seite des Behälters und der Klappdeckel in Richtung einer zweiten, gegenüberliegenden Seite des Behälters zu öffnen. Die entsprechenden Schwenkachsen von Klappboden und Klappdeckel befinden sich entsprechend an gegenüberliegenden Seiten des Behälters. Unter Behälterseiten werden vorliegend die vorzugsweise etwa vertikal verlaufenden Behälterwände verstanden. Durch die sich gegenläufig öffnenden Klappen wird eine weitgehend diagonale Durchströmung des Behälters beim Absenken bewirkt.A good flow through the container during lowering can be realized according to the invention in that the folding bottom is articulated on a first side of the container and the hinged lid on a second, opposite side of the container. Folding floor and hinged lid can therefore be opened in opposite directions. The folding floor is to be opened in the direction of a first side of the container and the hinged lid in the direction of a second, opposite side of the container. The corresponding pivot axes of hinged bottom and hinged lid are correspondingly on opposite sides of the container. In the present case, container sides are understood as meaning the preferably approximately vertically extending container walls. By the valves opening in opposite directions a largely diagonal flow through the container is effected during lowering.

Zur Entleerung des Probenbehälters über Tage weist der Behälter vorzugsweise eine Entleerungsklappe auf. Die Entleerungsklappe befindet sich vorzugsweise an einer Seitenwand des Behälters. Die Entleerungsklappe kann an dem Behältergehäuse angelenkt oder vollständig von dem Behältergehäuse lösbar sein. Zum sicheren Verschließen während der Probennahme ist die Entleerungsklappe vorzugsweise verriegel- beziehungsweise abschließbar.For emptying the sample container for days, the container preferably has an emptying flap. The emptying flap is preferably located on a side wall of the container. The emptying flap may be hinged to the container housing or completely detachable from the container housing. For safe closing during sampling, the emptying flap is preferably lockable or lockable.

Zum Einbringen des Behälters in das Bodenloch zur Entnahme der Probe weist der Behälter vorzugsweise eine Kopplungseinrichtung zum Koppeln mit einem Halteelement auf. Die Kopplungseinrichtung ist vorzugsweise seitlich neben dem Behälter angeordnet, so dass der Behälter nach oben und unten frei zugänglich ist und sich insbesondere der Klappdeckel frei öffnen lässt. Bei dem Halteelement kann es sich beispielsweise um ein Seil oder eine Stange handeln.For introducing the container into the bottom hole for taking out the sample, the container preferably has a coupling device for coupling to a holding element. The coupling device is preferably arranged laterally next to the container so that the container is freely accessible upwards and downwards and in particular the hinged lid can be opened freely. The retaining element may be, for example, a rope or a rod.

Vorzugsweise ist eine Schubstange zum Absenken des Behälters in das Loch und zum Anheben des Behälters aus dem Loch vorgesehen. Durch die Schubstange, welche ein Halteelement bildet, lässt sich sowohl eine Druckkraft zum Absenken des Behälters als auch eine Zugkraft zum Anheben des Behälters aufbringen. Insbesondere bei hochviskosen Füllungen lässt sich durch die Schubstange der Behälter mit einer größeren Geschwindigkeit in das erstellte Loch absenken.Preferably, a push rod is provided for lowering the container into the hole and for lifting the container out of the hole. By the push rod, which forms a holding element, both a pressure force for lowering the container and a tensile force for lifting the container can be applied. Especially with highly viscous fillings can be lowered by the push rod, the container at a greater speed in the created hole.

Besonders bevorzugt ist es nach der Erfindung, dass eine Verbindungseinrichtung zum Befestigen des Behälters an einem Fräs- oder Bohrwerkzeug vorgesehen ist. Beispielsweise kann der Behälter an einem Rahmenelement eines Fräs- oder Bohrwerkzeugs befestigt werden und so gleichzeitig mit der Erstellung des Loches in das Loch abgesenkt werden. Bei der Erstellung eines Schlitzes im Boden mittels mehreren rotierenden Bohrwendeln, die über zumindest ein nicht-rotierendes Querjoch miteinander verbunden sind, lässt sich der Behälter beispielsweise an dem Querjoch befestigen. Bei der Verwendung einer Schlitzwandfräse kann der Behälter zum Beispiel oberhalb entsprechender Fräsräder an einem Fräsrahmen angebracht werden. Die Verbindungseinrichtung ermöglicht eine Probennahme während der Bohrlocherstellung, was insbesondere bei einem sogenannten "in-situ"-Verfahren vorteilhaft ist, bei welchem das aushärtbare Bodenelement im Boden durch Vermischung eines aushärtbaren Mediums mit abgetragenem Bodenmaterial erstellt wird.It is particularly preferred according to the invention that a connecting device is provided for fastening the container to a milling or drilling tool. For example, the container can be attached to a frame member of a milling or drilling tool and so lowered simultaneously with the creation of the hole in the hole. When creating a slot in the ground by means of a plurality of rotating drilling helices, which are connected to each other via at least one non-rotating transverse yoke, the container can for example be attached to the transverse yoke. When using a trench wall cutter, the container can be mounted, for example above corresponding cutting wheels on a milling frame. The connecting device allows sampling during the hole creation, which is particularly advantageous in a so-called "in-situ" method, in which the curable soil element is created in the soil by mixing a curable medium with ablated soil material.
