Abstract
Eine Baumaschine besitzt eine Vibrationseinheit zum Rütteln eines Bodens zur Verdichtung des Bodens. Erfindungsgemäß ist an der Baumaschine wenigstens ein Beschleunigungssensor angeordnet, der aufgrund seiner Anordnung Beschleunigungsmesswerte der Vibrationseinheit erfasst. Der Beschleunigungssensor ist mit einer Auswerteeinheit verbunden, welche dazu eingerichtet ist, anhand der Beschleunigungsmesswerte ein Maß der Verdichtung des Bodens zu ermitteln und auszugeben.A construction machine has a vibration unit for vibrating a soil to compact the soil. According to the invention, at least one acceleration sensor is arranged on the construction machine, which due to its arrangement detects acceleration measurement values of the vibration unit. The acceleration sensor is connected to an evaluation unit which is set up to determine and output a measure of the compaction of the soil on the basis of the acceleration measured values.
Description
Die Erfindung betrifft eine Baumaschine mit einer Vibrationseinheit, insbesondere einen Tiefenrüttler.The invention relates to a construction machine with a vibration unit, in particular a deep vibrator.
Diese Maschinen haben die Aufgabe in einer Tiefe von mehreren Metern den Untergrund durch eingebrachte Vibrationen zu verdichten. Das Verdichten des Untergrundes erhöht die Belastungsfähigkeit des Bodens. Um die Belastbarkeit des Untergrundes noch weiter zu erhöhen, ist es üblich Schottersteine in den Untergrund einzubringen, die durch den Tiefenrüttler ebenfalls verdichtet werden. Auf diese Weise erhöht sich die Belastungsfähigkeit eines Untergrundes weiter und es ist möglich große Bauvorhaben auch auf zuerst nicht tragfähigem Untergrund zu errichten.These machines have the task of compacting the subsoil at a depth of several meters by introducing vibrations. The compaction of the ground increases the load capacity of the soil. In order to increase the load capacity of the substrate even further, it is common practice to introduce ballast stones into the ground, which are also compacted by the deep vibrator. In this way, the load capacity of a subsoil continues to increase and it is possible to build large construction projects on unsustainable ground.
Solche Tiefenrüttler sind aus der Patentliteratur bekannt. Beispielhaft sei auf die
Um den Fortschritt der Verdichtung zu erfassen und zu dokumentieren, wird im Moment der nötige Hydraulikdruck im Vortriebszylinder des Rüttlers gemessen. Dieses Verfahren ist von vielen verschiedenen Parametern abhängig und aus diesem Grund mit einer hohen Ungenauigkeit behaftet.In order to record and document the progress of compaction, the necessary hydraulic pressure is currently measured in the propulsion cylinder of the vibrator. This method depends on many different parameters and therefore has a high degree of inaccuracy.
Der Erfindung liegt die Zielsetzung zugrunde, eine Erfassung der erzielten Verdichtung bei einer Baumaschine mit Vibrationseinheit zu verbessern.The invention is based on the objective to improve a detection of the achieved compression in a construction machine with vibration unit.
Dieses Ziel wird mit einer Baumaschine gemäß den Merkmalen des Patentanspruchs 1 erreicht. This object is achieved with a construction machine according to the features of patent claim 1.
Durch einen an der Baumaschine angeordneten Beschleunigungssensor mit dem Beschleunigungsmesswerte der Vibrationseinheit erfasst werden und eine Auswerteeinheit, die dazu eingerichtet ist, anhand der Beschleunigungsmesswerte ein Maß der Verdichtung des Bodens zu ermitteln und auszugeben kann die erzielte Verdichtung zuverlässiger als bisher erfasst werden.By an acceleration sensor arranged on the construction machine with the acceleration measured values of the vibration unit being detected and an evaluation unit which is set up to determine and output a measure of the compaction of the soil on the basis of the acceleration measured values, the achieved compaction can be detected more reliably than hitherto.
Die Erfindung bewirkt also eine Verbesserung der Erfassung der Bodenverdichtung insbesondere beim Tiefenrüttler und damit die Schaffung einer Dokumentationsmöglichkeit des Verdichtungsfortschritts. Somit kann beurteilt werden, in wieweit der einzelne Verdichtungsvorgang abgeschlossen ist. Ebenso kann zu Nachweiszwecken gegenüber dem Auftraggeber eine aussagekräftige Dokumentation der verrichteten Gesamtarbeit erstellt werden.Thus, the invention causes an improvement in the detection of soil compaction, especially in Tiefenrüttler and thus the creation of a documentation option for compaction progress. Thus, it can be judged to what extent the single compaction process is completed. Likewise, for the purpose of proof to the client, a meaningful documentation of the completed complete work can be produced.
Bevorzugte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Preferred developments of the invention are subject of the dependent claims.
Bevorzugte Stellen um einen oder mehrere Beschleunigungssensoren anzubringen sind z.B. beim Tiefenrüttler an der Rüttlerspitze, an dem Aufsatzrohr, an der Halterung bzw. dem Mast, an dem Ausleger und/oder an einem Rahmen des Tiefenrüttlers. Auf die genannten Bauteile übertragen sich die beim Rütteln erzeugten Vibrationen recht gut.Preferred locations for attaching one or more acceleration sensors are e.g. at the deep vibrator at the Rüttlerspitze, at the attachment tube, at the holder or the mast, at the boom and / or at a frame of the deep vibrator. On the components mentioned, the vibration generated during shaking transferred quite well.
Vorzugsweise kann die Auswerteeinheit in ein Steuergerät der Baumaschine integriert sein. Alternativ oder zusätzlich kann die Auswerteeinheit mit dem Beschleunigungssensor eine Baueinheit bildet.Preferably, the evaluation unit can be integrated in a control device of the construction machine. Alternatively or additionally, the evaluation unit with the acceleration sensor forms a structural unit.
Besonders bevorzugt ist es, wenn ein Steuergerät vorhanden ist, das mit der Vibrationseinheit so verbunden ist, dass es die Vibrationseinheit ausschalten kann, wobei dem Steuergerät Signale der Auswerteeinheit zugeführt sind, und wobei das Steuergerät in Verbindung mit der Auswerteeinheit dazu eingerichtet ist, bei Auftreten oder Überschreiten von vorgegebenen Beschleunigungsmesswerten die Vibrationseinheit auszuschalten.It is particularly preferred if a control unit is present which is connected to the vibration unit in such a way that it can switch off the vibration unit, the control unit receiving signals from the evaluation unit, and the control unit being set up in connection with the evaluation unit when it occurs or exceeding predetermined acceleration readings to turn off the vibration unit.
Dabei kann automatisch der Verdichtungsvorgang beendet werden, wenn das gemessene Beschleunigungssignal einen voreingestellten Wert überschreitet, da die maximal mögliche Verdichtung erreicht ist. Das System kann auch dazu verwendet werden den Verdichtungsvorgang sofort zu beenden, falls die Rüttelspitze auf massive Gesteinsschichten trifft. Wird dies nicht erkannt und sofort abgeschaltet, kann dies ansonsten zur Beschädigung der Maschine führen.In this case, the compression process can be automatically terminated when the measured acceleration signal exceeds a preset value, since the maximum possible compression is reached. The system can also be used to immediately stop the compaction process if the shaker tip hits massive rock layers. If this is not detected and switched off immediately, this can otherwise damage the machine.
Vorteilhaft ist es auch die Auswerteeinheit mit einer Aufzeichnungseinheit zu verbinden, welche dazu eingerichtet ist, das Maß der Verdichtung des Bodens insbesondere in Zusammenhang mit weiteren Daten zu erfassen uns so einen Verdichtungsfortschritt zu dokumentieren. Die weiteren Daten können z .B. Zeitdaten oder Ortsdaten (GPS-Daten) oder eine Kennzeichnung der Verdichtungsstelle im Geländeplan sein.It is also advantageous to connect the evaluation unit to a recording unit which is set up to record the degree of compaction of the soil, in particular in conjunction with other data, so as to document a compaction progress. The further data can, for example. Time data or location data (GPS data) or an identification of the compression point in the site plan.

Während des Verdichtungsvorgangs werden die Beschleunigungswerte kontinuierlich gemessen. Die gemessenen Beschleunigungswerte werden zu der Auswerteeinheit
Beurteilt werden die Veränderung der gemessenen Beschleunigungswerte im Zuge des Verdichtungsvorganges, sowie die Verhältnisse der gemessenen Beschleunigungswerte an den verschiedenen Messstellen zueinander. Übersteigt das gemessene Beschleunigungssignal einen voreingestellten Wert, so wird der Verdichtungsvorgang beendet, da die maximal mögliche Verdichtung erreicht ist.The change in the measured acceleration values in the course of the compression process as well as the ratios of the measured acceleration values at the different measuring points to each other are assessed. If the measured acceleration signal exceeds a preset value, the compression process is terminated, since the maximum possible compression is achieved.
Das System kann auch dazu verwendet werden den Verdichtungsvorgang sofort zu beenden, falls die Rüttlerspitze
