Abstract

To set up catenary support along railway lines, prefabricated concrete posts (11) are driven in as foundation by a ramming device (2-12) travelling on the railway line. A catenary support is then joined to every post rammed in. This procedure makes possible a substantial saving in time and cost, particularly as no excavation is necessary for the mast foundation. The ramming device is designed and dimensioned so that it remains within the required clearance gauge in the working and transportation position. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Einrichtung zum Einrammen von Fundamentpfählen für Leitungsmasten an einem Bahngeleise, mit einer auf dem Bahngeleise fahrbaren Hilfsvorrichtung mit einstellbarem Mäkler und einer am Mäkler angeordneten Rammvorrichtung. Eine solche Einrichtung ist bekannt aus der DE-AS 1 814 767. Der Mäkler ist hierbei mit einem schwenkbar und verschiebbar auf einem Geleisefahrzeug angeordneten Schlitten schwenkbar verbunden und kann mittels eines hydraulischen Zylinders aufgerichtet werden, der zwischen dem Schlitten und dem Mäkler wirkt. Der Mäkler kann auch in der Art eines Auslegers geneigt ausgeschwenkt werden und mit dem Mäkler verbundene Stützen können dann als Mäkler wirkend am Boden seitlich der Rammstelle abgestützt werden. In dieser Arbeitsstellung ist aber eine rasche und genaue Lagebestimmung der als Mäkler wirkenden Stützen nicht möglich. Es ist insbesondere in keiner Arbeitsstellung des Mäklers möglich, mittels des Mäklers ein sicheres, schnelles Bestimmen der Lage und Richtung des Pfahls zu bestimmen.The present invention relates to a device for ramming foundation piles for line masts on a railroad track, with an auxiliary device which can be moved on the railroad track with an adjustable leader and a ramming device arranged on the leader. Such a device is known from DE-AS 1 814 767. The leader is in this case pivotally connected to a carriage arranged pivotably and displaceably on a track vehicle and can be erected by means of a hydraulic cylinder which acts between the carriage and the leader. The leader can also be tilted out in the manner of a boom and supports connected to the leader can then be supported as a leader on the ground to the side of the ramming point. In this working position, however, it is not possible to determine the position of the supports acting as brokers quickly and precisely. In particular, in no working position of the leader, it is possible to use the leader to determine the position and direction of the pile safely and quickly.

Ziel der Erfindung ist es, eine Einrichtung und ein Verfahren anzugeben, welche ein besonders schnelles und zuverlässiges Richten und Rammen von Fundamentpfählen vom Bahngeleise aus gewährleisten. Die Lösung besteht darin, dass der Mäkler schwenkbar mit einem starren, schwenkbaren Ausleger verbunden ist und mittels einem zwischen Ausleger und Mäkler wirksamen Zylinder der Winkel zwischen Ausleger und Mäkler einstellbar ist, und dass der Mäkler mittels eines weiteren Zylinders gegenüber dem Ausleger höhenverstellbar ist. Die genaue Bestimmung der Stellung des Mäklers bezüglich des Auslegers mittels eines Zylinders erlaubt es, von der einzigen Bedienungsstelle auf dem Geleisefahrzeug aus die Stellung des Mäklers genau und praktisch starr zu bestimmen. Es ist insbesondere auch möglich, über den Ausleger und den Mäkler einen mit dem Mäkler gekuppelten Pfahl mit erheblichen Kräften zu richten, bevor er endgültig eingerammt wird.The aim of the invention is to provide a device and a method which ensure particularly fast and reliable straightening and ramming of foundation piles from the railway track. The solution is that the leader is pivotally connected to a rigid, pivotable boom and the angle between the boom and leader can be adjusted by means of a cylinder acting between the boom and leader, and that the leader is height-adjustable relative to the boom by means of another cylinder. The exact determination of the position of the leader with respect to the boom by means of a cylinder allows the position of the leader from the only operating point on the track vehicle to determine precisely and practically rigid. In particular, it is also possible, with the aid of the boom and the leader, to straighten a post coupled to the leader with considerable force before it is finally driven in.

Die Möglichkeit, den Mäkler mittels des weiteren Zylinders in der Höhe zu verstellen, ist für ein rationelles, präzises Arbeiten wesentlich, weil es möglich ist, den einmal genau positionierten Mäkler zum Rammen am Boden abzustützen und zur Korrektur dieser Position, bzw. zum Richten eines Pfahls vorübergehend vom Boden abzuheben.The possibility of adjusting the leader by means of the additional cylinder is essential for efficient, precise work, because it is possible to support the leader, who has been positioned exactly, for ramming on the ground and for correcting this position or straightening one To lift the stake off the ground temporarily.

Die erfindungsgemässe Vorrichtung erlaubt auch die Durchführung eines besonders vorteilhaften Rammverfahrens, welches dadurch gekennzeichnet ist, dass man vorerst bei am Boden neben der Rammstelle abgestütztem Mäkler den Pfahl ein Stück einrammt, dann den Mäkler vom Boden abhebt und mit dem Mäkler den damit gekuppelten Pfahl ausrichtet, hierauf den Mäkler in der ausgerichteten Lage wieder an den Boden absenkt und dann den Pfahl endgültig einrammt. Dieses Verfahren erweist sich als besonders rationell zur Erzielung hoher Genauigkeit der Position gerammter Pfähle. Dabei können die mittels eines besonderen, über den Ausleger geführten Seilzugs herangeschafften und aufgerichteten Pfähle an der vorbezeichneten Rammstelle abgestellt und vorerst mittels einiger Schläge ein Stück eingerammt werden. Hierauf wird der Mäkler vom Boden abgehoben und der vorgerammte Pfahl wird durch koordinierte Bewegungen des Auslegers und des Mäklers, die praktisch starr steuerbar sind, genau senkrecht gerichtet. Dann kann der Mäkler wieder abgesenkt und am Boden abgestützt werden, worauf der Pfahl endgültig eingerammt wird.The device according to the invention also allows a particularly advantageous ramming method to be carried out, which is characterized in that the pile is first rammed in with the leader supported on the ground next to the ramming point, then the leader is lifted off the ground and aligned with the leader the pile coupled with it the leader is then lowered to the ground in the aligned position and then the pile is finally rammed in. This method proves to be particularly efficient for achieving high accuracy in the position of rammed piles. The piles brought up and erected by means of a special cable run over the boom can be parked at the aforementioned ramming point and a piece of ramming can be done for the time being. Then the leader is lifted from the ground and the pile is directed vertically by coordinated movements of the boom and leader, which are practically rigidly controllable. Then the leader can be lowered again and supported on the ground, whereupon the pile is finally rammed in.

Hierbei kann man aus dem Rammfortschritt auf die Bodeneigenschaften schliessen und die Pfahllänge den Bodeneigenschaften entsprechend wählen, um die erwünschteHere one can deduce the soil properties from the progress of the pile driving and choose the pile length according to the soil properties to achieve the desired one

Standfestigkeit des Fundamentes zu erreichen. Es können vorzugsweise Pfahlteilstücke nach dem Einrammen des oder der vorhergehenden Teilstücke aufgesetzt und eingerammt werden.To achieve stability of the foundation. Pile sections can preferably be put on and driven in after driving in the previous section or sections.

Die Hilfsvorrichtung kann sowohl in ihrer Arbeitsstellung bei quer zur Fahrtrichtung stehendem Ausleger als auch in ihrer Transportstellung bei in Fahrtrichtung liegendem Ausleger auf ihren nicht am Ausleger anliegenden Seiten innerhalb des geforderten Lichtraumprofils bleiben. Die Hilfsvorrichtung kann somit auf allen Geleiseanlagen transportiert und eingesetzt werden, wobei sie bei doppelspurigen Geleiseanlagen weder in ihrer Transport- noch in ihrer Arbeitsstellung den Zugsverkehr auf dem zweiten Geleise behindert. Es wird also nicht nur eine kurze Bauzeit erreicht, sondern während derselben bleibt auch die Behinderung des Bahnverkehrs so gering als möglich.The auxiliary device can remain within the required clearance profile in its working position with the boom standing transversely to the direction of travel and in its transport position with the boom lying in the direction of travel on its sides not resting on the boom. The auxiliary device can thus be transported and used on all track systems, and in the case of double-track track systems it does not hinder train traffic on the second track either in its transport position or in its working position. Not only is a short construction time achieved, but the disability of the rail traffic remains as low as possible during this time.

Vorzugsweise kann die Hilfsvorrichtung quer zur Fahrtrichtung verschiebbar angeordnet sein. Sie kann beispielsweise auf der Ladebrücke eines Tiefladewagens schwenkbar montiert sein, welche Ladebrücke zusammen mit der Hilfsvorrichtung bezüglich der Drehgestelle quer zur Fahrtrichtung verschiebbar ist. Zusätzlich können Abstützzylinder zum Abstützen der Hilfsvorrichtung, bzw. der Ladebrücke am Bahnkörper vorgesehen sein. Damit kann eine optimale Ausladung und Standfestigkeit der Hilfsvorrichtung erzielt werden, und es ist dabei leichter möglich, innerhalb des geforderten Lichtraumprofils von 1,575 m ab Geleiseachse zu bleiben.The auxiliary device can preferably be arranged to be displaceable transversely to the direction of travel. For example, it can be pivotally mounted on the loading bridge of a flat-bed wagon, which loading bridge can be moved transversely to the direction of travel together with the auxiliary device with respect to the bogies. In addition, support cylinders can be provided to support the auxiliary device or the loading bridge on the web body. This means that the auxiliary device can be optimally unloaded and stable, and it is easier to stay within the required clearance profile of 1.575 m from the track axis.

Mit dem oberen Ende jedes gerammten Pfahles kann ein Ortsbetonkopf oder ein vorfabrizierter Kopf verbunden werden, auf dem dann der Mast montiert wird.An in-situ concrete head or a prefabricated head can be connected to the top end of each rammed pile, on which the mast is then mounted.

Die Erfindung wird nun anhand eines Ausführungsbeispiels näher erläutert, welches in der Zeichnung zum Teil schematisch dargestellt ist.The invention is now based on an embodiment explained in more detail, which is partially shown schematically in the drawing.

  • Figur 1 zeigt eine Seitenansicht der Rammvorrichtung in Arbeitsstellung, wobei die Ladebrücke des Tiefladewagens geschnitten dargestellt ist,FIG. 1 shows a side view of the ramming device in the working position, the loading bridge of the flatbed truck being shown in section,
  • Figuren 2 und 3 zeigen schematisch die Transportstellung der Rammvorrichtung in Seiten- bzw. Stirnansicht,FIGS. 2 and 3 schematically show the transport position of the ramming device in side and end views,

  • Figur 6 zeigt das obere Ende des gerammten Pfahles mit einem Betonkopf.Figure 6 shows the top of the rammed pile with a concrete head.

Die in Figur 1 dargestellte Rammvorrichtung weist einen Seilbagger auf, der auf der Ladebrücke 1 eines Tiefladewagens schwenkbar montiert ist. Der Ausleger 2 des Baggers kann in bekannter Weise in seiner Neigung verstellt werden. Sein oberes Ende ist über ein Gelenk 3 mit einer Längsführung 4 für einen Mäkler 5 verbunden. Die Neigung zwischen dem Ausleger 2 und dem Mäkler 5 kann mittels eines zwischen der Führung 4 und dem Ausleger 2 angeordneten hydraulischen Zylinders 6 verstellt werden. Am un-- teren Ende der Führung -4 greift die Kolbenstange 7 eines hydraulischen Zylinders 8 an, dessen unteres Ende mit dem Mäkler 5 verbunden ist. Der Zylinder 8 dient der Höhenverstellung des Mäklers 5 in der Führung 4.The ramming device shown in Figure 1 has a cable excavator, which is pivotally mounted on the loading bridge 1 of a flatbed truck. The boom 2 of the excavator can be adjusted in its inclination in a known manner. Its upper end is connected via a joint 3 to a longitudinal guide 4 for a leader 5. The inclination between the boom 2 and the leader 5 can be adjusted by means of a hydraulic cylinder 6 arranged between the guide 4 and the boom 2. At the lower end of the guide -4, the piston rod 7 engages a hydraulic cylinder 8, the lower end of which is connected to the leader 5. The cylinder 8 serves to adjust the height of the leader 5 in the guide 4.

Am Mäkler 5 ist ein Rammbär 9 von beispielsweise 3 t Gewicht längsverschiebbar geführt. Er kann mittels eines Seils 10, das über Umlenkrollen am oberen Ende des Mäklers 5 geführt ist, aufgezogen und fallengelassen werden, um einen unter ihm befindlichen vorfabrizierten Betonpfahl 11 einzurammen. Auf dem oberen Ende des Betonpfahls 11 sitzt eine Schlagkappe 12, die am Mäkler 5 geführt ist, und die den Pfahl mit dem Mäkler kuppelt und in der Schlagrichtung des Rammbärs 9 hält. Der Mäkler 5 ist seitlich des Pfahls 11 auf den Bahnkörper abgestützt. Da das Zugseil 10 über das obere Ende des Mäklers geführt und dort abgestützt ist, nimmt der Mäkler beim Aufziehen des Rammbärs dessen Gewicht und auch eventuelle dynamische Belastungen beim Anheben des Bärs und beim Fallenlassen desselben auf. Der Bagger und der Tiefladewagen werden somit während des Rammens von diesen Kräften entlastet.On the leader 5, a battering bear 9 of, for example, 3 t weight is guided in a longitudinally displaceable manner. It can be pulled up and dropped by means of a rope 10, which is guided over deflection rollers at the upper end of leader 5, in order to drive in a prefabricated concrete pile 11 located below it. On the upper end of the concrete pile 11 sits a striking cap 12, which ge on the leader 5 leads, and which couples the pole with the leader and holds in the direction of the battering ram 9. The leader 5 is supported on the side of the pile 11 on the web body. Since the pull rope 10 is guided over the upper end of the leader and supported there, the leader takes up the weight of the ramming bear and also any dynamic loads when lifting the bear and dropping it. The excavator and the low loader wagon are relieved of these forces during ramming.

Ueber das obere Ende des Mäklers 5 ist ein weiteres Zugseil 13 geführt, welches jeweils dem Stellen und gegebenenfalls dem Antransport von zu rammenden Pfählen dient. Wie Figur 1 zeigt, sind an der Ladebrücke 1 des Tiefladewagens beidseitig des Baggers Abstützzylinder 14 angebracht. Der oder die Zylinder an der Seite, nach welcher der Ausleger 2 ausgeschwenkt ist, sind betätigt und halten Stützplatten 15 zur Stabilisierung des Wagens und der Rammvorrichtung am Bahnkörper.Another traction rope 13 is guided over the upper end of leader 5, which serves in each case for the positioning and possibly the transport of piles to be rammed. As FIG. 1 shows, support cylinders 14 are attached to the loading bridge 1 of the low-loader truck on both sides of the excavator. The cylinder or cylinders on the side after which the boom 2 is pivoted out are actuated and hold support plates 15 for stabilizing the carriage and the ramming device on the web body.

Figur 1 zeigt, dass die Ladebrücke 1 mit dem Bagger asymmetrisch bezüglich der Drehgestelle des Tiefladewagens liegt. Tatsächlich kann die Ladebrücke gegenüber den Drehgestellen quer zur Fahrtrichtung nach beiden Seiten hin um beispielsweise 20 cm verschoben und in der verschobenen Lage blockiert werden, um eine möglichst grosse Ausladung des Baggers, bzw. der Rammvorrichtung und anderseits auch eine Verschiebung des Baggergehäuses in dem Sinne zu erzielen, dass hinter diesem Gehäuse, d.h. auf der dem Ausleger gegenüberliegenden Seite mit Sicherheit keine Teile mehr über das geforderte, strichpunktiert angedeutete Lichtraumprofil L vorstehen. Bei Doppelspurbetrieb bleibt somit das benachbarte Geleise für den normalen Zugsverkehr frei.Figure 1 shows that the loading bridge 1 with the excavator is asymmetrical with respect to the bogies of the flatbed truck. In fact, the loading bridge can be shifted in relation to the bogies transversely to the direction of travel on both sides by, for example, 20 cm and blocked in the shifted position in order to maximize the radius of the excavator or ramming device and, on the other hand, to shift the excavator housing accordingly achieve that behind this housing, ie on the side opposite the boom, there are no longer any parts that protrude beyond the required, dash-dotted light space profile L. With double-track operation, the adjacent track remains free for normal train traffic.

Figuren 2 und 3 zeigen in schematischer Darstellung die Transportstellung der Rammvorrichtung. Der Ausleger 2 ist nach unten gelassen und liegt parallel zur Fahrtrichtung. Die Ladebrücke 1 ist in ihre normale Mittelstellung auf den Drehgestellen verschoben, so dass die ganze Anlage etwa symmetrisch zum Geleise liegt. Der Mäkler 5 ist ganz zum Ausleger 2 angezogen, und diese Teile sowie der Rammbär 9 sind auf eine feste Stütze 16 der Ladebrücke 1 abgestützt. Die Breite des Baggergehäuses ist so bemessen, dass es auch in dieser Stellung innerhalb des geforderten Lichtraumprofils L liegt und problemlos mit der Bahn transportiert werden kann. Am einen Ende der Ladebrücke ist ein Aggregat 17 zur Versorgung der Rammvorrichtung mit Betriebsmitteln, insbesondere Drucköl und Elektrizität vorgesehen. Auf der Ladebrücke sind Lampen 18 montiert, da jedenfalls bei einspurigen Bahnanlagen die Rammvorrichtung üblicherweise nachts in Betrieb ist.Figures 2 and 3 show a schematic representation of the transport position of the ramming device. The boom 2 is lowered and is parallel to the direction of travel. The loading bridge 1 is shifted into its normal middle position on the bogies, so that the entire system is approximately symmetrical to the track. The leader 5 is fully attracted to the boom 2, and these parts and the ram bear 9 are supported on a fixed support 16 of the loading bridge 1. The width of the excavator housing is dimensioned so that in this position it is within the required clearance profile L and can be easily transported by train. At one end of the loading bridge there is an assembly 17 for supplying the ramming device with operating resources, in particular pressure oil and electricity. Lamps 18 are mounted on the loading bridge, since the ramming device is usually in operation at night in the case of single-track railway systems.

Die zu rammenden Pfähle sind Schleuderbetonpfähle mit einem Durchmesser von beispielsweise 350 mm und einer Länge von 4 m. Sie sind an den Enden mit Kupplungsringen versehen, die zum Kuppeln übereinandergesetzter Pfahlstücke miteinander verschweisst werden können. Nachdem ein erstes solches Teilstück des Pfahls eingerammt ist, wird nötigenfalls ein zweites Teilstück aufgesetzt und verschweisst, die Verbindungsstelle mit Korrosionsschutz versehen und dann der Pfahl weiter eingerammt. Die Länge des Pfahls wird dadurch bestimmt, dass der Rammfortschritt und daraus die Tragfähigkeit des Bodens laufend ermittelt und die Pfahllänge entsprechend gewählt wird. Das letzte Pfahlteilstück wird eingerammt, bis ein oberes Ende von beispielsweise 20 bis 30 cm Höhe noch aus dem Boden ragt. Um dieses Ende kann dann ein Ortsbetonkopf gegossen werden, in welchen Montageschrauben für den aufzusetzenden Leitungsmast eingegossen werden. Nach dem Abbinden des Kopfes kann der Sockel des Leitungsmastes mit demselben verschraubt werden.The piles to be rammed are spun concrete piles with a diameter of, for example, 350 mm and a length of 4 m. They are provided with coupling rings at the ends, which can be welded together to couple stacked pile pieces. After a first such section of the pile has been rammed in, a second section is, if necessary, put on and welded, the connection point provided with corrosion protection and then the pile further rammed in. The length of the pile is determined by continuously determining the progress of the pile driving and the load-bearing capacity of the soil and selecting the pile length accordingly. The last section of the pile is driven in until an upper end, for example 20 to 30 cm high, still protrudes from the ground. A local concrete head can then be poured around this end, into which assembly screws for the line mast to be fitted are cast. After tying off the head, the base of the line can be masts are screwed to the same.

Beim Rammen braucht der Mäkler nicht unbedingt genau senkrecht zu stehen. Da er also in der Höhe und in der Neigung frei einstellbar ist, kann man auch in schwierigem Gelände in weiten Grenzen in beliebigem Abstand und auf beliebigem Niveau, bezogen auf das Geleise, Fundamentpfähle rammen, und zwar bis zu einem Abstand von 7 m von der Geleiseachse. Das Einrammen kann hierbei mit relativ grosser Präzision erfolgen, beispielsweise bezüglich Höhe und Abstand vom Geleise auf + 5 cm genau.The leader does not necessarily have to be exactly vertical when ramming. Since it can be freely adjusted in height and inclination, you can ram foundation piles within wide limits at any distance and at any level, based on the track, up to a distance of 7 m from the, even in difficult terrain Track axis. The ramming can take place with relatively great precision, for example with respect to the height and distance from the track to an accuracy of + 5 cm.

Die Figuren 4 und 5 zeigen eine Variante der Rammvorrichtung in zwei typischen Arbeitsstellungen. Entsprechende Teile sind gleich bezeichnet wie in Figur 1. Der Mäkler 5 weist am unteren Ende eine umklappbare Verlängerung 5a auf. Figur 4 zeigt den Fall, in welchem sich das Geleise auf einem Damm befindet, neben welchem die Fundamentpfähle 11 einzurammen sind. Zudem ist der Abstand vom Geleise beträchtlich. Der Ausleger 2 ist daher mit geringer Neigung weit ausgelegt. Der Mäkler weist bei heruntergeklappter Verlängerung 5a seine volle Länge auf und ist am Boden abgestützt. Der Pfahl ist ganz eingerammt. Es soll nun nochmals der ganze Vorgang zum Rammen eines Pfahls beschrieben werden.Figures 4 and 5 show a variant of the ramming device in two typical working positions. Corresponding parts are identified in the same way as in FIG. 1. The leader 5 has a foldable extension 5a at the lower end. FIG. 4 shows the case in which the track is on a dam, next to which the foundation piles 11 are to be driven. The distance from the track is also considerable. The boom 2 is therefore designed with a low inclination. When the extension 5a is folded down, the leader has its full length and is supported on the ground. The pile is completely rammed in. The entire process for ramming a pile will now be described again.

Zuerst wird mittels geeigneter Vermessungsgeräte die Rammstelle in Bezug auf das Geleise genau festgelegt und markiert. Dann wird bei angehobenem Mäkler mittels des Seils 13 ein bereitliegender Pfahl aufgezogen und mit der Spitze an die markierte Rammstelle gestellt. Dann wird die Rammkappe 12, die am Bär 9 angehängt war, durch Senken des Bärs auf den Pfahl aufgesetzt und vom Bär gelöst. Damit ist das obere Pfahlende mit dem Mäkler gekuppelt und gehalten. Das Seil 13 wird nun gelöst und mittels des Zylinders 8 der Mäkler in die dargestellte Lage auf den Boden gestellt. Dann wird der Pfahl durch einige Schläge-mit dem Bär 9 ein Stück, z.B. um 50 cm, eingerammt. Hierauf wird der Bär 9 angehoben und durch koordinierte Steuerung des Auslegers 2 und der Position des Mäklers 5 gegenüber dem Ausleger 2 mittels des Zylinders 6 wird der Pfahl genau in die Rammrichtung, im allgemeinen senkrecht, gerichtet. Dann wird der Mäkler mittels des Zylinders 8 wieder an den Boden gestellt und dann weitergerammt. Ist ein erstes Pfahlstück gerammt und soll ein zweites aufgesetzt werden, wird die Rammkappe 12 mit dem Bär 9 gekuppelt und mit demselben angehoben. Dann kann wiederum dank der vielseitigen Bewegungssteuerung von der Bedienungskabine aus der Mäkler mittels des Zylinders 8 vom Boden abgehoben und dann weggeschwenkt, z.B. mittels des Zylinders 6 nach innen geschwenkt werden, um den Raum über dem eingerammten Pfahl zum Aufsetzen des weiteren Pfahlstücks und zum Verschweissen der Kupplungsringe freizugeben. Nach dem Kuppeln der Pfahlstücke wird der Mäkler wieder in seine Arbeitslage gebracht und an den Boden abgestellt, die Rammkappe 12 wird auf das obere Pfahlstück aufgesetzt und vom Bär 9 entkuppelt und dann kann schon weitergerammt werden.First, the ramming point is precisely defined and marked in relation to the track using suitable measuring devices. Then, with the leader raised, a ready pile is pulled up by means of the rope 13 and placed with the tip at the marked ramming point. Then the ram cap 12, which was attached to the bear 9, is placed on the post by lowering the bear and detached from the bear. The top of the pile is now coupled and held with the leader. The rope 13 is now released and placed by means of the cylinder 8 of the leader in the position shown on the floor. Then the stake is through a few blows - with the bear 9 rammed a piece, for example by 50 cm. Then the bear 9 is raised and by coordinated control of the boom 2 and the position of the leader 5 with respect to the boom 2 by means of the cylinder 6, the pile is directed exactly in the driving direction, generally vertically. Then the leader is placed on the ground again by means of the cylinder 8 and then rammed further. If a first pile piece is rammed and a second is to be put on, the ram cap 12 is coupled to the bear 9 and raised with the same. Then, thanks to the versatile movement control from the operator's cab, the leader can be lifted from the ground by means of the cylinder 8 and then swiveled away, for example by means of the cylinder 6, to be pivoted inwards in order to place the pile above it for placing the further pole piece and for welding Release clutch rings. After the pile pieces have been coupled, the leader is brought back into its working position and placed on the ground, the ram cap 12 is placed on the upper pile piece and uncoupled from the bear 9 and then ramming can already continue.

Figur 5 zeigt eine andere typische Arbeitsstellung der Rammvorrichtung. Der Pfahl 11 soll an einer Böschung und relativ nahe am Geleise eingerammt werden. Der Ausleger 2 ist hierbei steil aufgerichtet und der Mäkler ist durch Hochklappen seines unteren Endteils 5a verkürzt. Es ist damit belegt, dass die Rammvorrichtung in praktisch allen Fällen unabhängig vom Terrain eingesetzt werden kann. Diese vielseitige Einsatzfähigkeit zusammen mit der oben beschriebenen, praktisch starr steuerbaren Beweglichkeit der Vorrichtung erlaubt ein besonders rationelles, genaues Arbeiten unter praktisch beliebigen Gegebenheiten.Figure 5 shows another typical working position of the ramming device. The pile 11 is to be driven into a slope and relatively close to the track. The boom 2 is erected steeply here and the leader is shortened by folding up its lower end part 5a. This proves that the ramming device can be used in practically all cases regardless of the terrain. This versatility together with the above-described, practically rigidly controllable mobility of the device allows particularly efficient, precise work under practically any circumstances.

Nach dem vollständigen Einrammen des Pfahls bis auf einen Rest von beispielsweise etwa 50 cm kann auf das obere Pfahlende gemäss Figur 6 ein vorfabrizierter Betonsockel 19 aufgesetzt und genau in die gewünschte Stellung gerichtet werden. Damit können Ungenauigkeiten der Pfahlposition noch korrigiert werden. Der Sockel ist mit eingegossenen Schrauben 20 zum Aufschrauben eines Leitungsmastes versehen. Im Oberteil des Sockels ist ein T-förmiges Teil 21 aus Schaumkunststoff eingegossen, das bei Bedarf entfernt werden kann, um Kabel einzuziehen. Durch Injektionskanäle 22 kann von oben Mörtel in den Hohlraum zwischen dem Pfahl 11 und der Ausnehmung 23 des Sockels eingebracht werden.After the pile has been completely rammed in except for a remainder of, for example, approximately 50 cm, a prefabricated concrete base 19 can be placed on the upper pile end according to FIG. This can be used to correct inaccuracies in the pile position. The base is provided with cast-in screws 20 for screwing on a line mast. In the upper part of the base, a T-shaped part 21 made of foam plastic is cast in, which can be removed if necessary to pull in cables. Injection channels 22 can be used to introduce mortar from above into the cavity between the pile 11 and the recess 23 in the base.

Die Hilfs- oder Arbeitsvorrichtung kann auch anderen Zwecken dienen als dem Rammen vorfabrizierter Betonpfähle. Insbesondere kann mit dem Mäkler anstelle des Rammbärs ein Bohrkopf mit nach unten ragendem Bohrer verbunden werden. Mit diesem Bohrer können bestimmte Böden gelockert werden, die ein direktes Einrammen von Pfählen nicht erlauben würden. Die Bohrvorrichtung kann aber auch zur Erstellung eines Aushubs unter Absenken eines Rohrs zwecks nachträglicher Erstellung eines Ortsbetonpfahls dienen.The auxiliary or working device can also serve purposes other than ramming prefabricated concrete piles. In particular, a drill head with a downwardly projecting drill can be connected to the leader instead of the ram bear. With this drill, certain soils can be loosened that would not allow direct driving of piles. The drilling device can also be used to create an excavation while lowering a pipe for the subsequent creation of an in-situ concrete pile.

Anstelle eines Rammbärs kann eine andere Rammvorrichtung, z.B. ein Vibrator oder Dieselhammer am Mäkler angebracht werden, um vorfabrizierte Pfähle einzurammen.Instead of a ramming bear, another ramming device, e.g. a vibrator or diesel hammer is attached to the leader to drive in prefabricated piles.

Es sind weitere Varianten möglich. Anstelle des starren Auslegers 2 könnte ein hydraulisch teleskopierbarer Ausleger verwendet werden, welcher hinsichtlich der Einstellbarkeit der Mäklerposition noch grössere Freiheit bietet.Other variants are possible. Instead of the rigid boom 2, a hydraulically telescopic boom could be used, which offers even greater freedom with regard to the adjustability of the leader position.
