Description

Die Erfindung betrifft einen Pfahlschuh für einen Rammpfahl, wobei der Pfahlschuh eine Vortriebseite, welche in eine Rammrichtung weist, und eine Rückseite mit einem Widerlager aufweist, welches zum Aufsetzen und Abstützen eines Pfahlrohres ausgebildet ist, gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft weiter ein Gründungselement nach dem Oberbegriff des Anspruchs 10.The invention relates to a pile shoe for a driven pile, wherein the pile shoe has a propulsion side, which points in a driving direction, and a back with an abutment, which is designed for mounting and supporting a pile tube, according to the preamble of claim 1. The invention further relates a foundation element according to the preamble of claim 10.

Derartige Rammpfähle werden als Gründungselemente für Bauwerke oder zur Bodenverbesserung in lockeren oder weichen Böden eingesetzt. Der Rammpfahl wird dabei im Wesentlichen ohne Aushub von Bodenmaterial in den Boden eingetrieben, insbesondere mittels Rüttlern oder Rammen eingerüttelt oder eingerammt.Such piles are used as foundation elements for buildings or soil improvement in loose or soft soils. The driven pile is driven into the ground essentially without excavation of soil material, in particular vibrated or driven in by means of vibrators or rams.

Zum Bilden des Rammpfahles ist ein Pfahlrohr vorgesehen, welches aus mehreren, üblicherweise gleich aufgebauten Pfahlrohrelementen zusammengesetzt werden kann. Auf diese Weise kann der Rammpfahl je nach Anwendungsfall in seiner Länge angepasst werden. Am bodenseitigen Ende des Pfahlrohres befindet sich als Abschlusselement ein sogenannter Pfahlschuh. Dessen Außendurchmesser ist üblicherweise größer als der Durchmesser des dahinterliegenden Pfahlrohres. Beim Eintreiben des Rammpfahles wird aufgrund des durchmessergrößeren Pfahlschuhs ein gewisser Freiraum zwischen dem durch Eintreiben bewirkten Bohrloch und dem darin angeordneten Pfahlrohr erzeugt. Über den inneren Rohrhohlraum des Pfahlrohres kann von der Bodenoberseite eine aushärtbare Masse, insbesondere auf Zementbasis, in das Bohrloch eingeleitet werden. Über Durchgänge am Pfahlrohr kann die fließfähige aushärtbare Masse auch in den Freiraum an der Außenseite des Pfahlrohres dringen, so dass nach Aushärten der aushärtbaren Masse das Pfahlrohr als Versteifungs- oder Verstärkungselement in dem Gründungspfahl verbleibt.To form the pile pile a pile tube is provided, which can be composed of several, usually the same structure pile pipe elements. In this way, the pile can be adjusted depending on the application in its length. At the bottom end of the pile tube is as a final element a so-called pile shoe. Its outer diameter is usually larger than the diameter of the underlying pile tube. When driving the pile pile is due to the larger diameter pile shoe, a certain amount of space between the drilled by driving hole and the pile tube arranged therein produced. About the inner tube cavity of the pile tube can be introduced from the bottom top a curable composition, in particular based on cement, in the borehole. About passages on the pile tube, the flowable curable material can also penetrate into the space on the outside of the pile tube, so that after hardening of the curable material, the pile tube remains as stiffening or reinforcing element in the foundation pile.

Ein derartiger Rammpfahl ist beispielsweise in der GB 2 351 516 A beschrieben. Der Rammpfahl ist dabei aus mehreren Pfahlrohrsegmenten aufgebaut, welche jeweils an ihrem rückwärtigen Rohrende eine Rohrerweiterung aufweisen. In die jeweilige Rohrerweiterung kann ein bodenseitiges, durchmesserkleineres Ende eines angrenzenden Pfahlrohrelementes eingesteckt werden. Am bodenseitigen Ende ist ein konischer Pfahlschuh aufgesetzt. An verschiedenen Positionen entlang jedes Pfahlrohrelementes sind Durchgänge zum radialen Austritt der aushärtbaren Masse vorgesehen. Das Einbringen derartiger radialer Durchgänge in eine Zylinderwandung etwa beim Gießen des Rohrelementes ist jedoch aufwändig. Zudem wird eine Ausnehmung oft nur am unteren Ende gewünscht, so dass sich das Bohrloch zuverlässig von unten auffüllt.Such a pile is, for example, in the GB 2 351 516 A described. The pile pile is constructed from several pile tube segments, which each have a pipe extension at its rear end of the pipe. In the respective pipe extension, a bottom, smaller-diameter end of an adjacent pile pipe element can be inserted. At the bottom end of a conical pile shoe is attached. Passages for radial exit of the hardenable mass are provided at different positions along each pile tube element. The introduction of such radial passages in a cylinder wall, for example, during the casting of the tubular element is complicated. In addition, a recess is often desired only at the lower end, so that the well reliably fills up from below.

Es ist bekannt, einen Rammpfahl aus Pfahlrohrelementen aufzubauen, welche zunächst gar keinen radialen Durchbruch aufweisen. Ein derartiger Rammpfahl wird beispielsweise in der DE 94 14 813 U1 oder in der NL 103 2168 C beschrieben. Bei derartigen Pfahlrohrelementen ist es üblich, dass an der Baustelle mit einem entsprechenden Werkzeug, etwa durch Trennschleifen oder Bohren, am bodenseitigen Ende des untersten Pfahlrohrelementes eine oder mehrere Ausnehmungen eingebracht werden, aus denen die aushärtbare Masse radial nach außen austreten kann.It is known to build a pile pile pile element, which initially have no radial breakthrough. Such a pile is used for example in the DE 94 14 813 U1 or in the NL 103 2168 C described. In such a pile pipe elements, it is common that at the site with a corresponding tool, such as cutting or drilling, at the bottom end of the lowest pile tube element one or more recesses are introduced, from which the hardenable mass can escape radially outward.

Ein derartiges nachträgliches Einbringen von Ausnehmungen ist jedoch zeit- und arbeitsaufwändig. Wird zudem eine Ausnehmung nicht in einer ausreichenden Größe hergestellt, kann der Durchtritt von aushärtbarer Masse durch das Pfahlrohr an die Außenseite beeinträchtigt sein. Dies kann dazu führen, dass der außenliegende Freiraum am Pfahlrohr nicht vollständig verfüllt ist, wodurch der Kontakt zum umgebenden Erdreich und damit die Tragfähigkeit des Gründungselementes beeinträchtigt sein können.However, such a subsequent introduction of recesses is time consuming and laborious. In addition, if a recess is not made in a sufficient size, the passage of curable material may be affected by the pile tube to the outside. This can lead to the outer free space on the pile tube is not completely filled, whereby the contact with the surrounding soil and thus the carrying capacity of the foundation element may be impaired.

Der Erfindung liegt die Aufgabe zugrunde, eine technische Lehre anzugeben, mit welcher einerseits ein Rammpfahl kostengünstig herstellbar ist und andererseits ein Gründungselement mit einem solchen Rammpfahl zuverlässig gefertigt werden kann.The invention has for its object to provide a technical teaching, with which on the one hand a pile pile is inexpensive to produce and on the other hand, a foundation element can be reliably manufactured with such a pile pile.

Die Erfindung wird durch einen Pfahlschuh für einen Rammpfahl mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen des erfindungsgemäßen Pfahlschuhes sind in den abhängigen Ansprüchen angegeben.The invention is achieved by a pile shoe for a pile with the features of claim 1. Preferred embodiments of the pile shoe according to the invention are specified in the dependent claims.

Der erfindungsgemäße Pfahlschuh ist dadurch gekennzeichnet, dass an dem Widerlager mindestens ein radial verlaufender Durchgang angeordnet ist, welcher zum Durchtritt eines Füllmateriales aus dem Innern des Pfahlrohres zur Außenseite des Pfahlrohres ausgebildet ist.The pile shoe according to the invention is characterized in that at least one radially extending passage is arranged on the abutment, which is formed for the passage of a filling material from the interior of the pile tube to the outside of the pile tube.

Ein Grundgedanke der Erfindung liegt darin, einen Durchgang für die aushärtbare Masse von der Pfahlrohrinnenseite zur Pfahlrohraußenseite nicht am Pfahlrohr vorzusehen, sondern einen Durchgang am Pfahlschuh auszubilden. Der Rammpfahl kann so in einer kostengünstigen Weise aus einem oder mehreren gleich aufgebauten Pfahlrohrelementen gebildet sein, ohne dass diese zwingend einen Durchgang aufweisen müssen. Das Pfahlrohr kann so insgesamt einfach und mit hoher Festigkeit gefertigt werden.A basic idea of the invention is not to provide a passage for the hardenable mass from the pile tube inner side to the pile tube outside on the pile tube, but to form a passageway on the pile shoe. The pile pile can thus be formed in a cost-effective manner from one or more identically constructed pile tube elements, without them necessarily having to have a passage. The pile tube can be made so overall easy and with high strength.

Gemäß der Erfindung werden ein oder mehrere radial gerichtete Durchgänge an dem vom Pfahlrohr separaten Pfahlschuh vorgesehen. Die fließfähige aushärtbare Masse kann somit unmittelbar am unteren Ende des Pfahlrohres aus dem Rohrinnenraum in den äußeren Freiraum austreten, so dass sich der ringförmige äußere Freiraum zuverlässig von unten mit aushärtbarer Masse füllen kann. Selbstverständlich kann der erfindungsgemäß ausgebildete Pfahlschuh auch mit Pfahlrohrelementen verwendet werden, welche zusätzlich Durchgänge aufweisen.According to the invention, one or more radially directed passages are provided on the pile shoe separate pile shoe. The flowable hardenable mass can thus emerge directly from the tube interior into the outer free space at the lower end of the pile tube, so that the annular outer space can reliably fill from below with curable material. Of course, the inventively designed pile shoe can also be used with pile tube elements, which additionally have passages.

Eine kostengünstige Ausführungsform der Erfindung besteht darin, dass die Vortriebsseite des Pfahlschuhes plattenförmig gestaltet ist. Ein besonders gutes Vordringen in den Boden wird erfindungsgemäß dadurch erreicht, dass die Vortriebsseite konisch ausgebildet ist. Der Außendurchmesser des etwa kreisförmigen Pfahlschuhs ist größer als der Außendurchmesser des aufzusetzenden Pfahlrohrs, so dass beim Eintreiben in den Boden ein ringförmiger äußerer Freiraum gebildet wird.An inexpensive embodiment of the invention is that the propulsion side of the pile shoe is designed plate-shaped. A particularly good penetration into the ground is inventively achieved in that the propulsion side is conical. The outer diameter of the approximately circular pile shoe is greater than the outer diameter of the aufzusetzenden pile tube, so that when driving into the ground, an annular outer space is formed.

Grundsätzlich kann der mindestens eine radial verlaufende Durchgang als ein tunnelartiger Kanal ausgebildet sein, welcher sich innerhalb des Pfahlschuhes erstreckt und eine innere Zutrittsöffnung und eine radial äußere Austrittsöffnung aufweist. Eine in fertigungstechnischer Hinsicht besonders effiziente Ausgestaltung besteht darin, dass das Widerlager eine ebene Auflagefläche aufweist, in welcher zum Bilden des Durchganges mindestens eine Ausnehmung eingebracht ist. Der Pfahlschuh kann so beispielsweise als ein einfaches Schmiedeteil oder Gussteil hergestellt sein. Der Pfahlschuh ist vorzugsweise aus Metall, insbesondere Stahl oder Grauguss, oder Beton gefertigt. Die Auflagefläche ist kreis- oder ringförmig und wird von der oder den Ausnehmungen unterbrochen.In principle, the at least one radially extending passage may be formed as a tunnel-like channel which extends within the pile shoe and has an inner access opening and a radially outer outlet opening. A particularly efficient design in terms of manufacturing technology is that the abutment has a flat support surface in which at least one recess is made to form the passage. The pile shoe may thus be made, for example, as a simple forging or casting. Of the Pile shoe is preferably made of metal, in particular steel or gray cast iron, or concrete. The support surface is circular or annular and is interrupted by the one or more recesses.

Eine gleichmäßige Festigkeit wird nach der Erfindung dadurch erzielt, dass die Vorderseite und die Rückseite des Pfahlschuhes im Wesentlichen symmetrisch zu einer Mittenachse ausgebildet sind. Vorzugsweise ist eine Grundform des Pfahlschuhs rotationssymmetrisch. Der Pfahlschuh kann aber auch eckig, polygonförmig oder mit einer anderen, von einer Kreisstruktur abweichenden Form ausgebildet sein.A uniform strength is achieved according to the invention in that the front and the back of the pile shoe are formed substantially symmetrically to a central axis. Preferably, a basic shape of the pile shoe is rotationally symmetrical. The pile shoe can also be square, polygonal or formed with another, deviating from a circular shape.

Grundsätzlich ist es ausreichend, dass in dem Pfahlschuh ein einzelner radialer Durchgang ausgebildet ist. Eine besonders effiziente und gleichmäßige Auffüllung des äußeren Ringraumes des Bohrloches wird nach einer weiteren Ausführungsform der Erfindung dadurch sichergestellt, dass mehrere Durchgänge vorgesehen sind, welche sich gleichmäßig über den Umfang des Widerlagers verteilen. Vorzugsweise sind 2, 3 oder 4 radial verlaufende Durchgänge eingeformt.In principle, it is sufficient that a single radial passage is formed in the pile shoe. A particularly efficient and uniform filling of the outer annular space of the borehole is ensured according to a further embodiment of the invention in that a plurality of passages are provided, which are distributed uniformly over the circumference of the abutment. Preferably, 2, 3 or 4 radially extending passages are formed.

Der oder die Durchgänge weisen eine radiale Erstreckung auf, welche größer als die Dicke der Rohrwandung des aufgesetzten Pfahlrohres ist. So wird eine sichere Umströmung des Pfahlrohres im Bereich des Pfahlschuhes von innen nach radial außen gewährleistet.The one or more passages have a radial extent which is greater than the thickness of the pipe wall of the patch pile pipe. This ensures safe flow around the pile tube in the area of the pile shoe from the inside to the outside.

Ein positionsgenaues Einbringen des Rammpfahles wird nach der Erfindung dadurch unterstützt, dass an der Rückseite des Pfahlschuhes eine Zentriereinrichtung vorgesehen ist, durch welche das Pfahlrohr zentrisch zur Mittenachse des Pfahlschuhes gehalten ist. Es kann sich hierbei um eine Innen- und/oder Außenzentrierung handeln.A positionally accurate introduction of the driven pile is supported according to the invention in that a centering device is provided on the back of the pile shoe, through which the pile tube is held centrally to the center axis of the pile shoe. This can be an interior and / or exterior centering.

Nach einer Ausführungsvariante der Erfindung ist es besonders bevorzugt, dass die Zentriereinrichtung mindestens zwei radial gerichtete Stege aufweist, welche sich konisch zur Mittenachse hin verjüngen. Es handelt sich hierbei um eine Innenzentrierung, wobei vorzugsweise 3 oder 4 gleichmäßig über den Umfang verteilte radiale Stege angeordnet sind. Durch die zur Mittenachse hin vorgesehene konische Verjüngung wird ein einfaches und zuverlässiges Aufsetzen des Pfahlrohres oder des untersten Pfahlrohrsegmentes auf den Pfahlschuh sichergestellt.According to one embodiment of the invention, it is particularly preferred that the centering device has at least two radially directed webs, which taper conically towards the center axis. This is an internal centering, preferably 3 or 4 evenly distributed over the circumference radial webs are arranged. By provided to the center axis conical taper a simple and reliable placement of the pile tube or the lowest pile tube segment is ensured on the pile shoe.

Weiter kann die Zentrierung dadurch verbessert sein, dass die Zentriereinrichtung eine Basis aufweist, deren Außenumfang an eine Innenseite des Pfahlrohres angepasst ist. Die Basis kann grundsätzlich einen ringförmigen Absatz oder ringsegmentförmige Absätze aufweisen, wobei der äußere Ringdurchmesser an den Innendurchmesser des aufzusetzenden Pfahlrohres angepasst ist, insbesondere mit diesem eine Spielpassung bildet.Further, the centering can be improved in that the centering device has a base whose outer circumference is adapted to an inner side of the pile tube. The base may in principle have an annular shoulder or ring-segment-shaped shoulders, wherein the outer ring diameter is adapted to the inner diameter of the aufzusetzenden pile tube, in particular forms a clearance fit with this.

Eine weitere zweckmäßige Ausgestaltung der Erfindung kann darin gesehen werden, dass an der Rückseite eine ringförmige Außenwand angeordnet ist, wobei bei aufgesetztem Pfahlrohr eine Außenseite des Pfahlrohres zur Innenseite der Umfangswand beabstandet und dabei ein Freiraum gebildet ist. Der Freiraum ist insbesondere ringförmig gestaltet. Der oder die radialen Durchgänge münden in diesen ringförmigen Freiraum. Die ringförmige Außenwand erstreckt sich axial nur in einem Teilbereich der Pfahllänge und stellt insbesondere bei besonders weichen und instabilen Böden sicher, dass ein möglichst ungehinderter Austritt der aushärtbaren Masse, insbesondere auf Zementbasis, aus dem Durchgang in den umgebenden ringförmigen Freiraum ermöglicht wird.A further expedient embodiment of the invention can be seen in that an annular outer wall is arranged on the rear side, with an outer side of the pile tube being spaced from the inner side of the peripheral wall when the pile tube is mounted, thereby forming a free space. The free space is designed in particular annular. The one or more radial passages open into this annular space. The annular outer wall extends axially only in a partial region of the pile length and, in particular in particularly soft and unstable soils, ensures that as free as possible an escape of the hardenable mass, in particular on a cement basis, from the passage into the surrounding annular space is made possible.

Die eingangs genannte Aufgabe wird zum anderen durch ein Gründungselement im Boden mit einem Rammpfahl gelöst, der ein Pfahlrohr, welches aus einem oder mehreren Pfahlrohrelementen zusammengesetzt ist, und einen Pfahlschuh am bodenseitigen Ende des Pfahlrohrs aufweist. Dieses Gründungselement ist dadurch gekennzeichnet, dass ein Pfahlschuh gemäß der vorbeschriebenen Erfindung vorgesehen ist.The object mentioned above is achieved, on the other hand, by a foundation element in the bottom with a driven pile, which has a pile tube, which is composed of one or more pile tube elements, and a pile shoe at the bottom end of the pile tube. This foundation element is characterized in that a pile shoe is provided according to the invention described above.

Das Pfahlrohr oder die Pfahlrohrelemente zum Bilden des Pfahlrohres sowie der Pfahlschuh können aus Metall, insbesondere Stahl oder Grauguss, oder aus Beton gebildet sein. Insbesondere bei einem Bilden des Rammpfahles mit einer Vielzahl von Pfahlrohrelementen weisen diese jeweils an ihrem bodenseitigen Ende eine Verjüngung und an ihrem bodenabgewandten Ende eine korrespondierende Durchmessererweiterung auf, so dass die Pfahlrohrelemente zuverlässig zusammengesteckt werden können.The pile tube or the pile tube elements for forming the pile tube and the pile shoe may be formed of metal, in particular steel or gray cast iron, or of concrete. In particular, when forming the pile pile with a plurality of pile tube elements, these each have at their bottom end a taper and at its bottom end facing away from a corresponding diameter extension, so that the pile tube elements can be reliably plugged together.

Eine bevorzugte Ausführungsform des erfindungsgemäßen Gründungselementes besteht darin, dass der Rammpfahl in einer ausgehärteten Masse eingebettet ist. Die ausgehärtete Masse ist insbesondere eine Zementmasse, welche innerhalb und außerhalb des Rammpfahles aufgrund eines Durchtrittes durch den Durchgang am Pfahlschuh angeordnet ist.A preferred embodiment of the foundation element according to the invention is that the driven pile is embedded in a hardened mass. The Hardened mass is in particular a cement paste, which is arranged inside and outside of the driven pile due to a passage through the passage at the pile shoe.

Der Pfahlschuh gemäß Fig. 1 ist im Wesentlichen kreisscheibenförmig mit einer flachen Vortriebsseite 12 ausgebildet, welche in eine Rammrichtung gerichtet ist. Auf einer von der Vortriebsseite 12 abgewandten Rückseite 14 ist zentrisch zu einer Mittenachse 24 eine Zentriereinrichtung 30 ausgebildet. Die Zentriereinrichtung 30 weist drei plattenförmige Stege 32 auf, welche sich von einem gemeinsamen Mittenbereich sternförmig radial nach außen erstrecken. Die drei Stege 32 sind gleichmäßig zu dem kreisförmigen Außenumfang 22 des Pfahlschuhs 10 in einem Winkel von 120° zueinander verteilt angeordnet. Die gleich ausgebildeten Stege 32 weisen jeweils eine bogenförmige Außenkante 36 auf, so dass sich die Stege 32 von einer unteren Basis 34 nach oben zur Mittenachse 24 hin verjüngen, wie aus Fig. 2 ersichtlich ist.The pile shoe according to Fig. 1 is formed substantially circular disc-shaped with a flat propulsion side 12, which is directed in a driving direction. On a rear side 14 facing away from the drive side 12, a centering device 30 is formed centrally with respect to a center axis 24. The centering device 30 has three plate-shaped webs 32, which extend from a common center region in a star-shaped manner radially outwards. The three webs 32 are evenly distributed to the circular outer periphery 22 of the pile shoe 10 at an angle of 120 ° to each other. The identically formed webs 32 each have an arcuate outer edge 36, so that the webs 32 taper from a lower base 34 up to the center axis 24 out, as from Fig. 2 is apparent.

An der Rückseite 14 ist ein Widerlager 16 mit einer ebenen Auflagefläche 18 gebildet, von welcher aus sich die Zentriereinrichtung 30 nach oben erstreckt. Die ebene Auflagefläche 18 ist ringförmig auf einem erhöhten kreisscheibenförmigen Plateau 26 ausgebildet und erstreckt sich um die Zentriereinrichtung 30 herum. Die ringförmige Auflagefläche 18 weist eine radiale Erstreckung auf, welche zur Aufnahme eines nicht dargestellten Pfahlrohres ausgebildet ist. Das Pfahlrohr weist dabei einen Innendurchmesser auf, welcher etwa dem durch die Basis 34 der Stege 32 aufgespannten Außendurchmesser entspricht.On the back 14, an abutment 16 is formed with a flat support surface 18, from which the centering device 30 extends upward. The level Support surface 18 is annular on an elevated circular disk-shaped plateau 26 and extends around the centering device 30 around. The annular bearing surface 18 has a radial extent, which is designed to receive a pile tube, not shown. The pile tube has an inner diameter which corresponds approximately to the spanned by the base 34 of the webs 32 outer diameter.

Die ringförmige Auflagefläche 18 ist durch drei zueinander um 120° versetzte Ausnehmungen zum Bilden von Durchgängen 20 unterbrochen. Die Durchgänge 20 stellen segmentförmige Ausnehmungen dar, welche eine radiale Erstreckung aufweisen, welche größer als eine Wanddicke des aufzusetzenden Pfahlrohres ist. Es verbleiben so axial gerichtete Ein- und Austrittsöffnungen. Auf diese Weise wird bei einem auf die Auflagefläche 18 aufgesetzten Pfahlrohr sichergestellt, dass eine innerhalb des Pfahlrohres zugeführte aushärtbare Masse über die Durchgänge 20 radial nach außen an die Außenseite des Pfahlrohres strömen kann.The annular bearing surface 18 is interrupted by three mutually offset by 120 ° recesses to form passages 20. The passages 20 represent segment-shaped recesses which have a radial extent which is greater than a wall thickness of the pile pipe to be erected. There remain so axially directed inlet and outlet openings. In this way, it is ensured in a patch on the support surface 18 post tube that a supplied within the pile tube curable material can flow through the passages 20 radially outwardly to the outside of the pile tube.

Beim Eintreiben eines Rammpfahles mit dem Pfahlschuh 10 wird im weichen Boden ein Bohrloch gebildet, dessen Bohrlochdurchmesser etwa dem Außenumfang 22 des Pfahlschuhs 10 entspricht. Auf diese Weise entsteht zwischen der so gebildeten Bohrlochwandung und dem durchmesserkleineren Außenumfang des aufgesetzten Pfahlrohres des Rammpfahles ein ringförmiger Freiraum um das Pfahlrohr. Dieser ringförmige Freiraum wird durch die aushärtbare Masse, insbesondere auf Zementbasis, verfüllt, welche durch die Durchgänge 20 hindurch in den ringförmigen äußeren Freiraum strömt.When driving a pile pile with the pile shoe 10, a borehole is formed in the soft soil, the borehole diameter corresponds approximately to the outer periphery 22 of the pile shoe 10. In this way arises between the borehole wall thus formed and the smaller diameter outer periphery of the patch pile tube of the pile pile an annular space around the pile tube. This annular space is filled by the hardenable mass, in particular cement-based, which flows through the passages 20 into the annular outer space.

Wie aus Fig. 3 ersichtlich, ist die ebene Auflagefläche 18 des Widerlagers 16 auf einem erhöhten kreisscheibenförmigen Plateau 26 ausgebildet. Das kreisscheibenförmige Plateau 26 ist gegenüber der kreisförmigen Vortriebsseite 12 durchmesserkleiner, so dass ein äußerer Absatz 28 gebildet ist.How out Fig. 3 can be seen, the flat bearing surface 18 of the abutment 16 is formed on an elevated circular disk-shaped plateau 26. The circular disk-shaped plateau 26 is smaller in diameter relative to the circular drive side 12, so that an outer shoulder 28 is formed.

Eine abgewandelte Ausführungsform eines erfindungsgemäßen Pfahlschuhs 10 ist in den Figuren 4 bis 6 dargestellt. Dieser entspricht weitgehend der Ausführungsform gemäß den Figuren 1 bis 3. Im Unterschied zu der vorausgegangenen Ausführungsform ist das kreisscheibenförmige Plateau 26 jedoch mit einem kleineren Durchmesser ausgebildet, so dass die drei Durchgänge 20 unmittelbar in den Absatz 28 münden. Auf diese Weise weisen die Durchgänge 20 auch eine radiale Austrittsöffnung 21 auf, wie insbesondere aus den Figuren 5 und 6 zu entnehmen ist.A modified embodiment of a pile shoe 10 according to the invention is in the FIGS. 4 to 6 shown. This corresponds largely to the embodiment according to the FIGS. 1 to 3 , In contrast to the previous embodiment, however, the circular disk-shaped plateau 26 is formed with a smaller diameter, so that the three passages 20 open directly into the shoulder 28. In this way, the passages 20 also have a radial outlet opening 21, in particular from the FIGS. 5 and 6 can be seen.

Die Zentriereinrichtung 30 entspricht der vorausgehend beschriebenen Zentriereinrichtung, wobei die Anordnung der drei Stege 32 um 60° versetzt zu der Anordnung der drei Durchgänge 20 ist, wie dies auch schon im vorausgegangen Ausführungsbeispiel dargestellt ist.The centering device 30 corresponds to the centering device described above, wherein the arrangement of the three webs 32 offset by 60 ° to the arrangement of the three passages 20, as shown in the previous embodiment.
