Gemäß der Erfindung ist vorgesehen, dass vor dem Aushärten der Füllmasse ein Datenträger in das Loch eingebracht wird, auf welchem Informationen zum erstellten Gründungselement gespeichert werden.The invention relates to a method and a device for creating a foundation element in the ground, wherein a hole is formed in the ground, which is filled to form the foundation element with a curable filler.

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 to form the foundation element with a curable composition, 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 working tool for creating a hole in the ground and a filling device for introducing a hardenable filling material 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.In particular, when creating large structures foundation elements are created in the ground. Such foundation elements may be bored piles or else slot walls or slot wall segments. In this case, a hole in the ground is created by means of a drill or a trench wall device, which is filled with a curable filler. The foundation elements can be used, for example, to support structural loads and remove them into deeper soil layers or to provide a groundwater protection so that groundwater can not enter an excavation 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 carrying capacity or groundwater barrier effect, these are to be carried out with great care. The execution is to be documented, so that a correct execution Even after the creation of the foundation element or the structure is overall traceable and verifiable. For this purpose, in particular, the construction equipment used can be provided with corresponding 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 drill is for example from the EP 3 081 737 A2 known. With this known drill can be detected and documented as a correct introduction of a support tube for a hole.

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.Usually, the documentation is carried out by means of a computer unit in the construction equipment, the data obtained are first transmitted to a central office. These can then be stored by the construction company or even with the client.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Erstellen eines Gründungselementes im Boden anzugeben, bei welchem eine besonders effiziente Dokumentation zu dem Gründungselement erfolgt.The invention has for its object to provide a method and apparatus for creating a foundation element in the ground, in which a particularly efficient documentation of the foundation element takes place.

Die Aufgabe wird nach der Erfindung zum einen durch ein Verfahren mit den Merkmalen des Anspruch 1 und zum anderen 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 having the features of claim 1 and on the other hand by a device having the features of claim 10. Preferred embodiments of the invention are indicated in the dependent claims.

Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass vor dem Aushärten der Füllmasse ein Datenträger in das Loch eingebracht wird, auf welchem Informationen zum erstellten Gründungselement gespeichert werden.The inventive method is characterized in that prior to curing of the filling material, 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 von 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.A basic idea of the invention can be seen in storing essential data for the created foundation element directly on or in the foundation element. In particular, in large construction sites, a plurality of foundation elements of several 100 pieces can be created, which can greatly complicate the assignment of stored data to individual foundation elements in retrospect. These difficulties are avoided by directly marking and / or storing the data in the foundation element. Furthermore, the advantage is achieved that even after a longer period of several years, for example at the onset of Damage to a single foundation element can be done quickly and specifically a cause determination by directly the data can be queried at the foundation element. With a corresponding data backup, even after decades, such as a demolition of the building, it can be relatively easily determined what effort 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 prior to curing of the filling compound and thus prior to curing of the foundation element in this. Thus, the disk is reliable and also arranged largely tamper-proof in the finished foundation element.

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 interrogated wirelessly after curing of the filling compound. The data carrier can be in particular a so-called RFID chip, which automatically sends a response signal with the desired data upon receipt of a corresponding electromagnetic signal. In this way a simple and non-destructive retrieval of the data carrier is possible at any time. The data carrier is preferably arranged in an upper region of the created foundation element, wherein the data carrier is preferably completely surrounded by filling compound, but still can be interrogated wirelessly.

Eine Weiterbildung der Erfindung besteht darin, dass die Informationen auf dem Datenträger fest gespeichert werden und nach Aushärten der Füllmasse die Informationen auf dem Datenträger unveränderbar sind. Vorzugsweise 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.A further development of the invention consists in that the information is stored permanently on the data carrier and, after the filling compound has hardened, the information on the data carrier is unchangeable. The data carrier preferably has a ROM memory element. This memory element is designed such that the data stored thereon can only be read, but not changed, at least after it has been introduced into the hole or the foundation element. Thus, the disk can serve as a kind of electronic certification, which is particularly tamper-proof and even after longer periods of time can be reliably queried.

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.Preferably, the data carrier is surrounded by a housing or a casing, which provides protection against the environment and in particular the aggressive filling material 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.Basically, almost any data can be stored on the disk, which are of interest for the founding element and its creation. It is preferred that dimensions, structure, production data and / or load capacity data of the foundation element are stored as information. With regard to the dimensions, in particular a depth and cross-sectional sizes of the created foundation element are of particular importance. With regard to the construction, in particular the type and amount of the filling compound used and the reinforcing materials can be stored. Particularly relevant are production data such as the course of the introduction of the hole and the introduction of the filling material. In particular, the information on the introduction of the filling material can give an indication as to whether possibly filling material has flowed unexpectedly in about cavities in the ground. Also, data regarding the manner of making the hole, the time required, as well as the machines and personnel employed, can be of particular importance. In particular, this may also be of relevance for a cost calculation, for example if a larger proportion of rock has occurred unexpectedly when creating a hole. With regard to the load capacity data, both setpoint data and actual load capacity data determined from the previously mentioned data can be stored for the specifically created foundation element. In addition, data can be stored at the time of creation, the construction company, the supplier of the filling material, etc., which may be of relevance at a later date.

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 one embodiment variant 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 slot wall segment by means of a slot wall device. Overall, the slot wall segments can also be created adjacent to one another, so that a slot wall, also referred to as a support or sealing wall, is formed therefrom.

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.A particularly high data security in the implementation of the method can be achieved in a preferred manner by the fact that the disk directly by a data transfer device to the drill or the slot wall device at Completion of the creation of the foundation element is described. The data carrier is thus automatically described and created by the respective construction equipment.

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.In principle, the data carrier thus described can then be pressed by an operator in a suitable manner on an upper region of the foundation element, in particular into the still soft filling compound. A further increase in reliability is achieved according to a development of the invention in that the data carrier described is introduced directly through a dispenser on the drill or the trench wall device in the hole in the ground. This can be done for example by a manipulator arm or preferably by an insertion tube or an insertion by gravity alone or by compressed air. Basically, an introduction of the data carrier on the normal concrete pump with the filling compound is possible. In particular, a plurality of data carriers with the information can be introduced into a foundation element, so that increased data security exists.

Eine besonders zuverlässige Anordnung des Datenträgers wird nach einer Verfahrensvariante der Erfindung dadurch erzielt, dass der Datenträger an einem Bewehrungselement angebracht wird, welches zum Bilden des Gründungselementes in das Loch eingebracht wird.
