Description

Die Erfindung betrifft ein Verfahren zum Erstellen eines Gründungselementes im Boden, bei dem ein Loch im Boden gebildet wird, welches zum Bilden des Gründungselementes mit einer aushärtbaren Masse verfüllt wird, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a method for creating a foundation element in the ground, in which a hole is formed in the ground which is filled with a hardenable mass to form the foundation element, according to the preamble of claim 1.

Die Erfindung betrifft weiterhin eine Vorrichtung zum Erstellen eines Gründungselementes im Boden mit einem Bodenbearbeitungswerkzeug zum Erstellen eines Lochs im Boden und einer Fülleinrichtung zum Einbringen einer aushärtbaren Füllmasse zum Bilden des Gründungselementes in dem Boden, gemäß dem Oberbegriff des Anspruchs 10.The invention further relates to a device for creating a foundation element in the ground with a soil cultivation tool for creating a hole in the ground and a filling device for introducing a hardenable filling compound for forming the foundation element in the ground, according to the preamble of claim 10.

Insbesondere beim Erstellen großer Bauwerke werden Gründungselemente im Boden erstellt. Derartige Gründungselemente können Bohrpfähle oder auch Schlitzwände oder Schlitzwandsegmente sein. Dabei wird mittels eines Bohrgerätes oder eines Schlitzwandgerätes ein Loch im Boden erstellt, welches mit einer aushärtbaren Füllmasse verfüllt wird. Die Gründungselemente können etwa dazu dienen, Bauwerkslasten abzustützen und in tiefere Bodenschichten abzutragen oder eine Grundwassersicherung bereitzustellen, so dass kein Grundwasser in eine Baugrube eintreten kann.Particularly when building large structures, foundation elements are created in the ground. Such foundation elements can be bored piles or diaphragm walls or diaphragm wall segments. A hole is created in the ground by means of a drilling device or a diaphragm wall device, which is filled with a hardenable filling compound. The foundation elements can serve, for example, to support structural loads and to carry them away into deeper soil layers or to provide groundwater protection so that no groundwater can enter a construction pit.

Aufgrund der wesentlichen Bedeutung der Gründungselemente für die Tragfähigkeit beziehungsweise Grundwassersperrwirkung sind diese mit großer Sorgfalt auszuführen. Die Ausführung ist dabei zu dokumentieren, so dass eine korrekte Ausführung auch noch nach der Erstellung des Gründungselementes oder des Bauwerkes insgesamt nachvollziehbar und überprüfbar ist. Hierzu kann insbesondere das eingesetzte Baugerät mit entsprechenden Mess- und Sensoreinrichtungen versehen sein, um die Erstellung eines Gründungselementes zu dokumentieren.Due to the essential importance of the foundation elements for the load-bearing capacity or the groundwater barrier effect, they must be carried out with great care. The execution is to be documented so that a correct execution is still comprehensible and verifiable as a whole even after the foundation element or the structure has been created. For this purpose, the construction equipment used can in particular be provided with appropriate measuring and sensor devices in order to document the creation of a foundation element.

Ein derartiges Bohrgerät ist beispielsweise aus der EP 3 081 737 A2 bekannt. Mit diesem bekannten Bohrgerät kann etwa ein korrektes Einbringen eines Stützrohres für eine Bohrung erfasst und dokumentiert werden.Such a drilling device is for example from EP 3 081 737 A2 famous. With this known drilling device, for example, correct insertion of a support tube for a borehole can be recorded and documented.

Üblicherweise erfolgt die Dokumentation mittels einer Rechnereinheit in dem Baugerät, wobei die erhaltenen Daten zunächst zu einer Zentrale übertragen werden. Diese können dann von dem Bauunternehmen oder auch bei dem Bauherrn abgespeichert werden.The documentation is usually carried out by means of a computer unit in the construction device, with the data received first being transmitted to a control center. These can then be saved by the construction company or by the client.

Ein gattungsgemäßes Verfahren zum Erstellen eines Gründungselementes geht aus der US 2011/200068 A1 hervor. Vor einem Aushärten des Gründungselementes wird in die aushärtende Masse eine Sensoranordnung eingebracht, welche Parameter innerhalb des Gründungselementes misst. Die Messwerte können in einem Datenspeicher gespeichert und nach außen übertragen werden.A generic method for creating a foundation element is based on US 2011/200068 A1 emerged. Before the foundation element hardens, a sensor arrangement is introduced into the hardening mass, which measures parameters within the foundation element. The measured values can be stored in a data memory and transferred to the outside.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Erstellen eines Gründungselementes im Boden anzugeben, bei welchen eine besonders effiziente Dokumentation zu dem Gründungselement erfolgt.The invention is based on the object of specifying a method and a device for creating a foundation element in the ground, in which a particularly efficient documentation is carried out on the foundation element.

Die Aufgabe wird nach der Erfindung zum einen durch ein Verfahren mit den Merkmalen des Anspruch 1 und zum anderen durch ein Gründungselement mit den Merkmalen des Anspruchs 9, sowie durch eine Vorrichtung mit den Merkmalen des Anspruchs 10 gelöst. Bevorzugte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen angegeben.The object is achieved according to the invention on the one hand by a method with the features of claim 1 and on the other hand by a foundation element with the features of claim 9 and by a device with the features of claim 10. Preferred embodiments of the invention are given in the dependent claims.

Bei dem erfindungsgemäßen Verfahren ist vorgesehen, dass vor dem Aushärten der Füllmasse ein Datenträger in das Loch eingebracht wird, auf welchem Informationen zum erstellten Gründungselement gespeichert werden.In the method according to the invention, it is provided that, before the filling compound hardens, a data carrier is introduced into the hole on which information about the created foundation element is stored.

Eine Grundidee der Erfindung kann darin gesehen werden, wesentliche Daten zum erstellten Gründungselement unmittelbar an oder in dem Gründungselement zu hinterlegen. Insbesondere bei großen Baustellen kann eine Vielzahl von Gründungselementen von mehreren 100 Stück erstellt werden, was die Zuordnung abgespeicherter Daten zu einzelnen Gründungselementen im Nachhinein erheblich erschweren kann. Diese Schwierigkeiten werden durch ein direktes Markieren und/oder Abspeichern der Daten im Gründungselement vermieden. Des Weiteren wird der Vorteil erzielt, dass auch nach einer längeren Zeitspanne von mehreren Jahren etwa beim Auftreten vonA basic idea of the invention can be seen in storing essential data on the created foundation element directly on or in the foundation element. In particular on large construction sites, a large number of foundation elements of several 100 pieces can be created, which means that stored data can be assigned to can make individual foundation elements considerably more difficult in retrospect. These difficulties are avoided by directly marking and / or saving the data in the foundation element. Furthermore, the advantage is achieved that even after a longer period of several years, for example, when

Schäden an einem einzelnen Gründungselement schnell und gezielt eine Ursachenermittlung erfolgen kann, indem unmittelbar die Daten an dem Gründungselement abgefragt werden können. Bei einer entsprechenden Datensicherung kann selbst nach Jahrzehnten, etwa bei einem Abbruch des Bauwerks, relativ einfach festgestellt werden, welcher Aufwand für ein mögliches Entfernen des Gründungselementes zu erwarten ist.Damage to an individual foundation element can be quickly and specifically determined by the fact that the data on the foundation element can be queried directly. With a corresponding data backup, even after decades, for example when the structure is demolished, it is relatively easy to determine what expenditure is to be expected for a possible removal of the foundation element.

Dabei wird der Datenträger vor dem Aushärten der Füllmasse und damit vor dem Aushärten des Gründungselementes in diesen eingebracht. Damit ist der Datenträger zuverlässig und auch weitgehend manipulationssicher in dem fertiggestellten Gründungselement angeordnet.In this case, the data carrier is introduced into the foundation element before the filling compound hardens and thus before the foundation element hardens. The data carrier is thus arranged in the finished foundation element in a reliable and largely tamper-proof manner.

Nach einer bevorzugten Ausführungsform der Erfindung ist es vorgesehen, dass der Datenträger nach dem Aushärten der Füllmasse drahtlos abfragbar ist. Der Datenträger kann dabei insbesondere ein sogenannter RFID-Chip sein, der bei Empfang eines entsprechenden elektromagnetischen Signals automatisch ein Antwortsignal mit den gewünschten Daten absendet. Auf diese Weise ist so jederzeit ein einfaches und zerstörungsfreies Abfragen des Datenträgers möglich. Der Datenträger wird dabei vorzugsweise in einem oberen Bereich des erstellten Gründungselementes angeordnet, wobei der Datenträger vorzugsweise vollständig von Füllmasse umgeben ist, jedoch noch weiterhin drahtlos abfragbar ist.According to a preferred embodiment of the invention, it is provided that the data carrier can be queried wirelessly after the filling compound has hardened. The data carrier can in particular be a so-called RFID chip, which automatically sends a response signal with the desired data when a corresponding electromagnetic signal is received. In this way, a simple and non-destructive query of the data carrier is possible at any time. The data carrier is preferably arranged in an upper area of the created foundation element, the data carrier preferably being completely surrounded by filling compound, but still being able to be queried wirelessly.

Gemäß der Erfindung ist vorgesehen, dass die Informationen auf dem Datenträger fest gespeichert werden und nach Aushärten der Füllmasse die Informationen auf dem Datenträger unveränderbar sind. Erfindungsgemäß weist der Datenträger dabei ein ROM-Speicherelement auf. Dieses Speicherelement ist so ausgebildet, dass die darauf gespeicherten Daten zumindest nach dem Einbringen in das Loch beziehungsweise das Gründungselement nur noch gelesen, aber nicht mehr verändert werden können. Damit kann der Datenträger als eine Art elektronische Zertifizierung dienen, welche besonders manipulationssicher ist und auch noch nach längeren Zeiträumen zuverlässig abgefragt werden kann.According to the invention, it is provided that the information is permanently stored on the data carrier and that the information on the data carrier cannot be changed after the filling compound has hardened. According to the invention, the data carrier has a ROM storage element. This memory element is designed in such a way that the data stored on it can only be read, but no longer changed, at least after being introduced into the hole or the foundation element. The data carrier can thus serve as a type of electronic certification which is particularly tamper-proof and can be reliably queried even after longer periods of time.

Vorzugsweise ist der Datenträger mit einem Gehäuse oder einer Hülle umgeben, welche einen Schutz vor der Umgebung und insbesondere der aggressiven Füllmasse gewährt, jedoch insbesondere ein drahtloses Abfragen bei Empfang eines elektromagnetischen Signals erlaubt.The data carrier is preferably surrounded by a housing or a sleeve which provides protection from the environment and in particular from the aggressive filling compound granted, but in particular allows wireless interrogation upon receipt of an electromagnetic signal.

Grundsätzlich können auf dem Datenträger nahezu beliebige Daten abgespeichert werden, welche für das Gründungselement und dessen Erstellung von Interesse sind. Bevorzugt ist es dabei, dass als Informationen Dimensionen, Aufbau, Produktionsdaten und/oder Tragfähigkeitsdaten des Gründungselementes gespeichert werden. Bezüglich der Dimensionen sind insbesondere eine Tiefe und Querschnittsgrößen des erstellten Gründungselementes von besonderer Bedeutung. Hinsichtlich des Aufbaus kann insbesondere die Art und Menge der verwendeten Füllmasse sowie der Armierungsmaterialien abgespeichert werden. Besonders relevant sind Produktionsdaten wie der Verlauf des Einbringens des Lochs sowie des Einbringens der Füllmasse. Insbesondere die Angaben zum Einbringen der Füllmasse können einen Hinweis darauf geben, ob möglicherweise Füllmasse in unerwarteter Weise etwa in Hohlräume im Boden geflossen ist. Es können auch Daten bezüglich der Art und Weise der Erstellung des Lochs, des notwendigen Zeitaufwands sowie der eingesetzten Maschinen und des eingesetzten Personals von besonderer Bedeutung sein. Dies kann insbesondere auch für eine Kostenermittlung von Relevanz sein, etwa wenn beim Erstellen eines Lochs in unerwarteter Weise ein größerer Anteil an Felsgestein aufgetreten ist. Hinsichtlich der Tragfähigkeitsdaten können sowohl Solldaten als auch aus dem vorher angeführten Daten ermittelte tatsächliche Tragfähigkeitsdaten zu dem konkret erstellten Gründungselement abgespeichert werden. Daneben können auch Daten zum Erstellungszeitpunkt, der erstellenden Baufirma, des Lieferanten der Füllmasse etc. gespeichert werden, die zu einem späteren Zeitpunkt von Relevanz sein können.In principle, almost any data that is of interest for the foundation element and its creation can be stored on the data carrier. It is preferred here that the information about the dimensions, structure, production data and / or load-bearing capacity data of the foundation element is stored. With regard to the dimensions, the depth and cross-sectional size of the created foundation element are of particular importance. With regard to the structure, in particular the type and amount of the filling compound used and the reinforcement materials can be saved. Production data such as the course of the introduction of the hole and the introduction of the filling compound are particularly relevant. In particular, the information on the introduction of the filler compound can provide an indication of whether filler compound may have flowed into cavities in the ground in an unexpected manner. Data relating to the manner in which the hole was created, the time required and the machines and personnel used can also be of particular importance. This can also be of particular relevance for a cost calculation, for example if a larger proportion of rock has unexpectedly appeared when a hole was created. With regard to the load-bearing capacity data, both target data and actual load-bearing capacity data determined from the previously listed data can be saved for the concrete foundation element. In addition, data at the time of creation, the construction company producing the material, the supplier of the filling compound, etc. can also be stored, which can be of relevance at a later point in time.

Grundsätzlich kann ein beliebiges Gründungselement vorgesehen sein. Besonders vorteilhaft ist es nach einer Ausführungsvariante der Erfindung, dass das Gründungselement als ein Bohrpfahl mittels eines Bohrgerätes oder als ein Schlitzwandsegment mittels eines Schlitzwandgerätes erstellt wird. Die Schlitzwandsegmente können insgesamt auch angrenzend zueinander erstellt werden, so dass hieraus eine Schlitzwand, auch Stütz- oder Dichtwand genannt, gebildet wird.In principle, any foundation element can be provided. According to a variant embodiment of the invention, it is particularly advantageous that the foundation element is created as a bored pile by means of a drilling device or as a diaphragm wall segment by means of a diaphragm wall device. The diaphragm wall segments can also be created as a whole adjacent to one another, so that a diaphragm wall, also called a supporting or sealing wall, is formed from them.

Eine besonders hohe Datensicherheit bei der Durchführung des Verfahrens kann in bevorzugter Weise dadurch erzielt werden, dass der Datenträger unmittelbar durch eine Datenübertragungseinrichtung an dem Bohrgerät oder dem Schlitzwandgerät bei Abschluss der Erstellung des Gründungselementes beschrieben wird. Der Datenträger wird also automatisch durch das jeweilige Baugerät beschrieben und erstellt. Grundsätzlich kann der so beschriebene Datenträger dann von einer Bedienperson in einer geeigneten Weise an einem oberen Bereich des Gründungselementes angebracht, insbesondere in die noch weiche Füllmasse, eingedrückt werden. Eine weitere Erhöhung der Zuverlässigkeit wird nach einer Weiterbildung der Erfindung dadurch erreicht, dass der beschriebene Datenträger unmittelbar durch eine Abgabeeinrichtung an dem Bohrgerät oder dem Schlitzwandgerät in das Loch im Boden eingebracht wird. Dies kann etwa durch einen Manipulatorarm oder vorzugsweise durch ein Einführrohr oder eine Einführleitung allein durch Schwerkraft oder durch Druckluft erfolgen. Grundsätzlich ist auch eine Einbringung des Datenträgers über die normale Betonpumpe mit der Füllmasse möglich. Insbesondere können auch mehrere Datenträger mit den Informationen in ein Gründungselement eingebracht werden, so dass eine erhöhte Datensicherheit besteht.A particularly high level of data security when carrying out the method can preferably be achieved by attaching the data carrier directly to the drilling device or the diaphragm wall device through a data transmission device Completion of the creation of the foundation element is described. The data carrier is therefore automatically written to and created by the respective construction equipment. In principle, the data carrier described in this way can then be attached in a suitable manner by an operator to an upper region of the foundation element, in particular pressed into the still soft filling compound. According to a further development of the invention, a further increase in reliability is achieved in that the described data carrier is introduced directly into the hole in the ground by a delivery device on the drilling device or the trench wall device. This can be done for example by a manipulator arm or preferably by an insertion tube or an insertion line solely by gravity or by compressed air. In principle, it is also possible to bring in the data carrier with the filling compound using a normal concrete pump.

The advantages described above can be achieved in this case.

Eine bevorzugte Ausführungsform der Erfindung besteht darin, dass eine Abgabevorrichtung vorgesehen ist, mit welcher der Datenträger mit den gespeicherten Informationen in das Loch im Boden vor dem Aushärten der Füllmasse einbringbar ist. Die Abgabeeinrichtung kann einen Manipulatorarm oder eine Zuführeinrichtung, etwa mit einem Zuführrohr oder einer Zuführleitung sein. Der Datenträger kann dabei durch die Schwerkraft oder durch Druckluft in das Loch eingebracht werden. Dies kann in das Loch vor dem Einfüllen der Füllmasse oder nachträglich in die noch weiche Füllmasse vor dem Aushärten erfolgen.A preferred embodiment of the invention is that a dispensing device is provided with which the data carrier with the stored information can be introduced into the hole in the bottom before the filling compound hardens. The delivery device can be a manipulator arm or a feed device, for example with a feed pipe or a feed line. The data carrier can be introduced into the hole by gravity or by compressed air. This can be done in the hole before the filling compound is poured in or subsequently in the still soft filling compound before it hardens.

Grundsätzlich kann die Vorrichtung jedes geeignete Baugerät zum Erstellen eines Gründungselementes durch Verfüllen eines Lochs sein. Besonders bevorzugt ist es, dass die Vorrichtung als ein Bohrgerät oder ein Schlitzwandgerät ausgebildet ist. Das Schlitzwandgerät kann dabei als ein Schlitzwandgreifer oder vorzugsweise eine Schlitzwandfräse sein.In principle, the device can be any suitable construction device for creating a foundation element by filling a hole.
