Definitions
- the invention relates to a method for producing a pile.
- Piles are widely used in construction.
- the pre-drive tube is aligned, for example, by means of a leader, and is connected to a first winch via a generally two ropes with a deflection arranged over a head region of the leader. With another rope, which is also guided over the deflection in the head area of the leader, a ram is held, which is guided in the pre-drive tube or works.
- a sustainable ground serving as a closure for the ram tube closure means, for example of sandy or other material, expelled by the Rammbr to form a pile base.
- concrete or the like may be added.
- a reinforcement cage is set, filled with concrete and pulled the vortex tube again. It is also possible to carry out a so-called gravel pre-compaction, wherein the soil is improved in a corresponding area below and above the Pfahlabsetziefe by pounding of gravel and also slightly compacted.

Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Pfahls.The invention relates to a method for producing a pile.
Pfähle finden im Bauwesen vielfach Anwendung. Insbesondere im Bereich des Grundbaus kommen neben Bohr- insbesondere Rammpfähle zum Einsatz, bei welchen mittels Innen- oder Außenrammung ein Vortreibrohr in den Baugrund eingetrieben/gerammt wird. Rammpfähle sollen vor allem höhere Lasten tragen. Das Vortreibrohr wird dabei beispielsweise mittels eines Mäklers ausgerichtet und ist über in aller Regel zwei Seile mit einer über einen Kopfbereich des Mäklers angeordneten Umlenkung mit einer ersten Winde verbunden. Mit einem weiteren Seil, welches ebenfalls über die Umlenkung im Kopfbereich des Mäklers geführt ist, ist ein Rammbär gehalten, welcher im Vortreibrohr geführt ist bzw. arbeitet. Wird tragfähiger Baugrund erreicht, wird ein als Verschluss für das Rammrohr dienendes Verschlussmittel, beispielsweise aus sandigem oder anderem Material, mittels des Rammbären ausgetrieben zur Bildung eines Pfahlfußes. Dabei kann zusätzlich Beton oder ähnliches zugegeben werden. Anschließend wird ein Bewehrungskorb eingestellt, Beton eingefüllt und das Vortreibrohr dabei wieder gezogen. Dabei ist es auch möglich, eine sogenannte Kies-Vorverdichtung durchzuführen, wobei der Boden in einem entsprechenden Bereich unterhalb und oberhalb der Pfahlabsetztiefe durch Ausstampfen von Kies verbessert und auch etwas verdichtet wird.Piles are widely used in construction. In particular, in the field of basic construction in addition to drilling in particular piles are used, in which by means of internal or external ramming a Vortreibrohr driven into the ground / rammed. Rammpfähle should carry especially higher loads. In this case, the pre-drive tube is aligned, for example, by means of a leader, and is connected to a first winch via a generally two ropes with a deflection arranged over a head region of the leader. With another rope, which is also guided over the deflection in the head area of the leader, a ram is held, which is guided in the pre-drive tube or works. If a sustainable ground is reached, serving as a closure for the ram tube closure means, for example of sandy or other material, expelled by the Rammbären to form a pile base. In addition, concrete or the like may be added. Subsequently, a reinforcement cage is set, filled with concrete and pulled the vortex tube again. It is also possible to carry out a so-called gravel pre-compaction, wherein the soil is improved in a corresponding area below and above the Pfahlabsetziefe by pounding of gravel and also slightly compacted.
Im Unterschied zu der vorstehend beschriebenen Innenrammung werden mittels einer Außenrammung beispielsweise Fußplattenpfähle hergestellt, wobei zur Herstellung derselben Vortreibrohre Einsatz finden, welche an ihrem unteren Endbereich durch eine verlorengegangene Fußplatte beziehungsweise Bodenplatte als Verschlussmittel verschlossen werden. Es sind auch Techniken bekannt, bei welchen die Fußplatte nicht verloren geht. Unter Zuhilfenahme eines Mäklers wird über einen Rammbären, welcher insbesondere als Freifallbär, Diesel- oder Hydraulikbär ausgebildet sein kann, das Vortreibrohr/Rammrohr in den Baugrund abgeteuft. Der Rammbär arbeitet dabei auf dem Kopf des Rammrohres. Die Rammung wird wie bei der oben beschriebenen Innenrammung bis in tragfähige Bodenbereiche geführt. Anschließend wird ein Bewehrungskorb eingestellt und der Pfahlschaft betoniert unter gleichzeitigem oder nachfolgendem, auch schrittweisem Ziehen des Rammrohrs. Bei einer Außenrammung geht die Fußplatte dabei unter Umständen verloren, je nach eingesetzter Technologie. Durch das jetzt unten offene Rammrohr rutscht Beton nach und füllt den Pfahlschaft etwa bis zur Außenkante des Rammrohrs aus. Dabei kann die im Boden verlorengegangene Fußplatte die Aufstandsfläche des Pfahls bilden.In contrast to the inner ridge described above, for example, foot plate piles are produced by means of an external ramming, with pre-reaming tubes being used for producing the same, which are closed at their lower end area by a lost base plate or base plate as closure means. Techniques are also known in which the footplate is not lost. With the help of a Mäklers is about a ram, which can be designed in particular as a free-fall bear, diesel or hydraulic bear, the pre-drive pipe / Pipe drilled in the ground. The ram works on the head of the ram tube. The ramming is like in the inner ram described above into viable floor areas guided. Subsequently, a reinforcement cage is set and the pile shaft concreted with simultaneous or subsequent, even gradually pulling the ram. With an outer ram, the footplate may be lost, depending on the technology used. Concrete slips through the ram tube, which is now open at the bottom, and fills the pile shaft up to the outer edge of the ram tube. In this case, lost in the ground foot plate can form the footprint of the pile.
Nachteilig an den vorstehend beschriebenen Verfahren sowohl der Außen- als auch der Innenrammung sind die damit einhergehenden erheblichen Erschütterungen und Lärmbeeinträchtigungen. Besonders in dicht bebauten Gebieten führt diese zu erheblichen Beeinträchtigungen in der unmittelbaren Umgebung.A disadvantage of the above-described methods of both the outer and the inner ram are the associated considerable shocks and noise. Especially in densely built-up areas, this leads to considerable damage in the immediate vicinity.
Bei bekannten Bohrpfählen, die insbesondere für Anwendungen mit geringen Traglasterfordernissen vorgesehen werden, wird das Vortreibrohr bis zur Absetzteufe in einen Untergrund gebohrt. Das Vortreibrohr weist zumeist eine Bohrspitze auf. Beim Einreichen der Absetzteufe wird das Vortreibrohr aus dem Untergrund entfernt, wobei die Bohrspitze im Untergrund verbleibt. Beton wird beim Entfernen des Vortreibrohrs eingefüllt, wodurch ein Pfahlschaft ausgebildet wird. Dabei kann die im Boden verlorengegangene Bohrspitze die Aufstandsfläche des Pfahls bilden. Nachteilig am vorstehend beschriebenen Verfahren ist, dass keine Verankerung wie bei einem Pfahlfuß bei Rammpfählen erfolgt und nur geringe Lasten abgetragen werden könnenIn known bored piles, which are provided in particular for applications with low load requirements, the pre-drive pipe is drilled until the sedimentation depth into a subsoil. The pre-drive tube usually has a drill tip. When submitting the sedimentation, the pre-drive pipe is removed from the subsoil, leaving the drill bit in the ground. Concrete is filled in removing the pre-drive pipe, whereby a pile shaft is formed. In this case, lost in the soil drill bit can form the footprint of the pile. A disadvantage of the method described above is that no anchoring takes place as in a pile base in Rammpfählen and only small loads can be removed

This is to be understood as meaning an open and (re-) closable end part, because even if it is opened, at least a partial release of the end part from the device takes place at the same time.
Das Endteil kann beispielsweise als Bodenplatte ausgebildet sein oder eine Bodenplatte umfassen. Die Bodenplatte kann als verlorene Bodenplatte ausgebildet sein. Die Bodenplatte kann beispielsweise aus Metall ausgebildet sein. Das lösbare Endteil ist vorzugsweise aus Metall und besonders bevorzugt aus Gusseisen ausgebildet. Alternativ oder ergänzend kann das Endteil als Spitze ausgebildet sein oder eine Spitze umfassen, um ein Einbringen der Vorrichtung in den Boden zu erleichtern. Die Spitze weist beispielsweise einen dreieckigen Querschnitt auf. Das Endteil kann insbesondere eine Bodenplatte, insbesondere eine verlorene, und eine Spitze, insbesondere eine verlorene, aufweisen. Beispielweise kann die Bodenplatte unterseitig an der Vorrichtung angeordnet sein und die Spitze unterseitig an der Bodenplatte. Das Endteil kann beispielsweise auf einem Schneidkopf der Vorrichtung angeordnet werden. Das Endteil kann als verlorene Spitze ausgebildet sein. Unter einer verlorenen Bodenplatte und/oder einer verlorenen Spitze werden Bauteile verstanden, die im Laufe des Verfahrens im Untergrund verbleiben.The end part may be formed, for example, as a bottom plate or include a bottom plate. The bottom plate may be formed as a lost bottom plate. The bottom plate may be formed, for example, of metal. The detachable end part is preferably made of metal and particularly preferably of cast iron. Alternatively or additionally, the end part may be formed as a tip or include a tip to facilitate insertion of the device in the ground. The tip has, for example, a triangular cross-section. The end part can in particular have a base plate, in particular a lost one, and a tip, in particular a lost one. For example, the bottom plate may be disposed on the underside of the device and the tip on the underside of the bottom plate. The end part can be arranged for example on a cutting head of the device. The end part may be formed as a lost tip. Under a lost bottom plate and / or a lost tip components are understood that remain in the underground during the process.
Die Bodenplatte kann alternativ oder ergänzend seitlich zumindest einen überstehende Flügel und/oder eine Wendel aufweisen, um ein Eindrehen zu erleichtern. Der Flügel kann beispielsweise rotorartig ausgebildet sein, um ein "Einschrauben" bzw. Eindrehen in den Untergrund zu ermöglichen. Die Wendel kann beispielsweise schraubenwendelartig ausgebildet sein. Alternativ oder ergänzend kann die Vorrichtung selbst zumindest eine Wendel aufweisen, die an einer Außenseite der Vorrichtung angeordnet ist.The bottom plate may alternatively or additionally have laterally at least one protruding wing and / or a helix in order to facilitate a screwing. The wing may be formed, for example rotor-like, to allow a "screwing" or screwing into the ground. The helix may be formed, for example helical. Alternatively or additionally, the device itself may have at least one coil which is arranged on an outer side of the device.
Zum Eindrücken und/oder Eindrehen der Vorrichtung in den Untergrund kann diese in Wirkverbindung mit einer Einbringungsvorrichtung zur Übertragung eines Drucks- und/oder einer Drehung stehen.For pressing and / or screwing the device into the ground, it can be in operative connection with a delivery device for transmitting a pressure and / or a rotation.
Erfindungsgemäß wird ein mindestens ein Bindemittel aufweisendes körniges erstes (schüttfähiges) Material bei Erreichen einer vorgegebenen Absetzteufe in die Vorrichtung eingefüllt. Das erste Material ist besonders bevorzugt Trockenbeton. Das erste Material kann alternativ oder ergänzend Kies, Sand, Gestein und/oder Ähnliches umfassen. Voraussetzung ist, dass es sich körnig verhält. Eine Abbindung erfolgt durch Wasser aus dem umgebenden Bodematerial, sodass sich ein fester Pfahlfuß ausbilden kann. Die vorgegebene Absetzteufe entspricht der geplanten bzw. gewünschten Pfahltiefe bzw. Pfahllänge. Die Vorrichtung ist vorzugsweise entsprechend lang ausgebildet.According to the invention, a granular first (free-flowing) material having at least one binder is filled into the device when a predetermined settling step has been reached. The first material is particularly preferably dry concrete. The first material may alternatively or additionally comprise gravel, sand, rocks and / or the like. The condition is that it behaves grainy. A binding is done by water from the surrounding soil material, so that a solid pile base can form. The predetermined settling depth corresponds to the planned or desired pile depth or pile length. The device is preferably designed to be correspondingly long.
Um eine gute und sichere Verankerung des herzustellenden Pfahls zu ermöglichen, umfasst das Verfahren erfindungsgemäß, dass ein Pfahlfuß durch Verdichtung des ersten Materials durch eine Innenrammung ausgebildet wird. Das erste Material wird durch die Innenrammung zumindest teilweise aus der Vorrichtung in den Untergrund gedrückt. Hierbei werden umgebende Bodenmaterialien verdrängt und dadurch gleichzeitig verdichtet. Unterhalb der in den Untergrund eingebrachten Vorrichtung bildet sich ein Pfahlfuß aus, der im Wesentlichen kugelförmig bzw. tropfenförmig ausgebildet ist und dessen Durchmesser größer als der Durchmesser der zumindest teilweisen rohrförmig ausgebildeten Vorrichtung ist, welcher wiederum den Durchmesser des herstellbaren Pfahlschafts definiert. Der mittels des erfindungsgemäßen Verfahrens herstellbare Pfahlfuß weist Abschnitte auf, die seitlich über die Vorrichtung und den herstellbaren Pfahlschaft vorstehen und den Pfahl daher sicher verankern.In order to enable a good and secure anchoring of the pile to be produced, the method according to the invention comprises that a pile base is formed by compaction of the first material by an inner ramming. The first material is at least partially forced out of the device into the ground by the inner race. In the process, surrounding soil materials are displaced and thus compacted at the same time. Below the introduced into the ground device, a pile base is formed, which is formed substantially spherical or teardrop-shaped and whose diameter is greater than the diameter of the at least partially tubular device, which in turn defines the diameter of the producible pile shaft. The means of the invention Method manufacturable pile base has sections that protrude laterally beyond the device and the producible pile shaft and therefore anchor the pole safely.
Die Innenrammung erfolgt mittels eines Rammbärs. Der Rammbär wird erfindungsgemäß in die Vorrichtung eingeführt beziehungsweise in der Vorrichtung angeordnet. Dieser kann beispielsweise in kurzen Abständen wiederholt nach oben verfahren und dann nach unten auf das erste Material fallengelassen werden. Hierfür kann ein Mäkler verwendet werden, der in Wirkverbindung mit dem Rammbär steht. Der Mäkler kann beispielsweise über zumindest ein Seil in Wirkverbindung mit dem Rammbär stehen.The inner ramming is done by means of a ram. The ram is inventively introduced into the device or arranged in the device. This can for example be repeatedly moved at short intervals and then dropped down on the first material. For this purpose, a leader can be used, which is in operative connection with the Rammbär. The broker can, for example, be in operative connection with the ram via at least one rope.
Erfindungsgemäß wird ein Pfahlschaft durch Einfüllen von einem mindestens ein Bindemittel aufweisendem, bevorzugt auch körnigem, zweiten Material in die Vorrichtung ausgebildet. Für das zweite Material wird vorzugsweise Beton verwendet. Das zweite Material kann alternativ oder ergänzend Kies, Sand, Gestein, Trockenbeton und/oder Ähnliches umfassen. Bevorzugt ist, dass das zweite Material fließfähig, und insbesondere mit Wasser versetzt ist, so dass es abbindet, ohne auf Wasser aus dem angebundenen Bodenmaterial angewiesen zu sein. Das zweite Material unterscheidet sich vom ersten Material. Beispielsweise kann als erstes (schüttfähiges) Material Trockenbeton und als zweites (fließfähiges) Material Beton verwendet werden. Zur Ausbildung eines besonders robusten Pfahlschaftes wird vorzugsweise vor Ausbildung des Pfahlschafts, das heißt bevor das zweite Material in die Vorrichtung eingefüllt wird, ein Bewehrungskorb in die Vorrichtung eingeführt. Als Bewehrungskorb wird beispielsweise ein längliches Konstrukt aus einem Metallgitter verwendet. Das zweite Material wird bevorzugt nicht verdichtet. Besonders bevorzugt erfolgt keine Rammung, insbesondere Innenrammung, während der Einfüllung des zweiten Materials. Hierdurch können Erschütterungen und Lärmbeeinträchtigungen vermieden werden. Das zweite Material ist weiter bevorzugt selbstverdichtend, sodass ein stabiler Pfahlschaft entsteht.According to the invention, a pile shaft is formed by filling in a device comprising at least one binder, preferably also granular, second material. Concrete is preferably used for the second material. The second material may alternatively or additionally comprise gravel, sand, rock, dry concrete and / or the like. It is preferred that the second material is flowable, and in particular mixed with water, so that it sets, without relying on water from the tailed soil material. The second material is different from the first material. For example, dry concrete can be used as the first (pourable) material and concrete as the second (flowable) material. To form a particularly sturdy pile shaft, a reinforcing cage is preferably introduced into the device before the pile shaft is formed, that is to say before the second material is introduced into the device. As a reinforcement cage, for example, an elongated construct of a metal grid is used. The second material is preferably not compacted. Particularly preferred is no ramming, in particular inner ramming, during the filling of the second material. As a result, shocks and noise can be avoided. The second material is more preferably self-compacting, resulting in a stable pile shaft.
Erfindungsgemäß umfasst das Verfahren, dass die Vorrichtung aus dem Untergrund entfernt wird. Die Vorrichtung wird besonders bevorzugt ohne Drehung zur Entfernung aus dem Untergrund herausgezogen. Alternativ kann die Vorrichtung auch mit Drehung oder insbesondere einer Kombination von Ziehen und Drehen aus dem Untergrund herausgezogen werden. Bevorzugt erfolgt während der Entfernung der Vorrichtung keine Innenrammung.According to the invention, the method comprises removing the device from the substrate. The device is particularly preferably withdrawn without rotation for removal from the ground. Alternatively, the device can also be pulled out of the ground with rotation or, in particular, a combination of pulling and turning. Preferably, during the removal of the device no inner ridge.
Besonders bevorzugt erfolgt die Entfernung der Vorrichtung aus dem Untergrund während der Ausbildung des Pfahlschafts. Hierdurch wird das in die Vorrichtung eingefüllte zweite Material besonders gleichmäßig in den beim Herausziehen der Vorrichtung freigegebenen Hohlraum im Untergrund verteilt.Particularly preferably, the removal of the device takes place from the substrate during the formation of the pile shaft. As a result, the filled into the device second material is particularly evenly distributed in the released when pulling out of the device cavity in the ground.
Besonders bevorzugt umfasst das erfindungsgemäße Verfahren, dass das Endteil von der Vorrichtung, insbesondere im Schritt der Innenrammung zur Ausbildung des Pfahlfußes, gelöst wird. Hierdurch wird ermöglicht, dass das erste Material zur Herstellung des Pfahlfußes aus der Vorrichtung in den Untergrund gelangen kann.Particularly preferably, the method according to the invention comprises that the end part of the device, in particular in the step of Innenrammung to form the pile base, is solved. This makes it possible that the first material for producing the pile base can get out of the device into the ground.
Vorzugsweise wird das Endteil durch die Innenrammung von der Vorrichtung gelöst. Das Endteil wird beispielsweise erst gelöst, nachdem das erste Material in die Vorrichtung eingefüllt wurde. Die Kraft der Rammung, die auf das eingefüllte erste Material ausgeübt wird, wird dann durch das erste Material zum Lösen des Endteils auf dieses übertragen. Vorzugsweise wird für die Innenrammung ein Rammbär in die Vorrichtung eingeführt.Preferably, the end part is released from the device by the inner race. The end part is, for example, only released after the first material has been introduced into the device. The force of the ram, which is exerted on the filled first material, is then transferred through the first material for releasing the end part on this. Preferably, a ram is introduced into the device for the inner ram.
Alternativ wird das Endteil dadurch gelöst, dass die Vorrichtung teilweise aus dem Untergrund zurück zur Bodenfläche bewegt wird und das Endteil sich dadurch von der Vorrichtung löst. Das bedeutet, dass das Endteil als ein verlorenes Endteil ausgebildet sein kann. Als Endteil kann wie vorbeschrieben beispielsweise eine verlorene Bodenplatte und/oder eine verlorene Spitze verwendet werden.Alternatively, the end part is achieved by moving the device partly out of the ground back to the bottom surface and thereby releasing the end part from the device. This means that the end part can be formed as a lost end part. As the end part as described above, for example, a lost bottom plate and / or a lost tip can be used.
Durch das erfindungsgemäße Verfahren kann vorteilhafter Weise unter nur geringen Erschütterungen ein Pfahl hergestellt werden, welcher eine nahezu gleiche oder ähnliche Tragfähigkeit wie ein Rammpfahl aufweist. Die geringen Erschütterungen werden dadurch erreicht, dass die Innenrammung erst nach Erreichen der Absetzteufe, das bedeutet tief unterhalb der Bodenoberfläche erfolgt. Lärmemissionen werden daher weitestgehend durch den Untergrund gedämpft.By means of the method according to the invention, it is advantageously possible, with only slight vibrations, to produce a pile which is almost identical or similar Carrying capacity as a pile has. The low vibrations are achieved by the fact that the inner ridge takes place only after reaching the sedimentation depth, ie deep below the soil surface. Noise emissions are therefore largely dampened by the subsoil.
