Definitions
- the invention relates to a device according to the preamble of claim 1.
- a device of this type is known from DE-OS 2 236 901.
- this known device uses more than one vibrating tube on a common leader only in the event that the vibrating tubes are arranged in a line next to one another and are used to produce a narrow diaphragm wall in the ground.
- a single vibrating tube can be used in the known device.
- Guide blades can be arranged on both sides of the tip of the vibrating tube for better guidance in the ground.
- Such a vibrating tube has a diameter of approximately 40 cm. This diameter cannot be increased significantly, since experience has shown that it is the optimum for penetration of the vibrating tube.
- the speed of penetration of a vibrating tube into the ground is greater, the smaller its diameter, the greater its vibrating frequency and the greater its vibration amplitude.
- the inside of the hollow vibrating tube is used in the known device as a concrete feed tube, which is open at the bottom of the vibrating tube.
- the concrete feed pipe is filled with pressurized concrete or the like during the penetration of the device into the ground so that no ground can penetrate into the open end of the feed pipe.
- piles with a larger diameter are either introduced in such a way that they are poured and hardened outside of the ground and then hammered into the ground by means of impact hammers with a high level of noise and vibration, or by previously drilling out the ground with a drill and then subsequently Concrete is filled into the resulting cavity.
- the invention is intended to improve a device of the type mentioned at the outset so that piles with the cross-section of a vibrating tube of 40 cm in diameter substantially exceeding closed cross-sections, the smallest cross dimension of which is ⁇ approximately 40 cm, are introduced into the ground in a simple and rapid manner can.
- the vibrating tubes which are rigidly connected to the displacement box, cause the entire device to vibrate in such a way that it can effectively penetrate the soil.
- the oblique sliding surfaces of the displacement box interact with the tips of the vibrating tubes to displace the soil.
- the closed cross-sectional shape of the device ensures favorable compaction of the displaced soil.
- the displacement box is preferably made of hollow steel sheet or the like.
- a cross-sectional ratio in which the cross-section of the displacement box is approximately 1: 2 to the sum of the cross-sections of all vibrating tubes has proven to be particularly expedient, although this ratio is not essential for the device according to the invention.
- Embodiments with two, three or four vibrating tubes are particularly advantageous.
- a material feed pipe is preferably arranged according to claim 3 in the displacement box, where it is best protected against damage and opens at the bottom near an opening of the displacement box. If it is to be avoided that soil penetrates into the displacement box, the two openings can also coincide.
- Claims 4 to 6 relate to advantageous configurations of devices for fixing the parts of the device to one another and to the leader carrying them.
- the opening of the displacement box can be closed after taking up the soil and thus the penetrated soil can be pulled out with the device.
- the displacement box is given a greater height so that it extends over the entire length of the vibrating tubes.
- three parallel vibrating tubes 10 are provided with conical tips 12 at their lower ends.
- the vibrating tubes 10 are arranged in approximately semicircular cross-sections of recesses of a common displacement box 16 made of hollow steel sheet.
- a common displacement box 16 made of hollow steel sheet.
- the displacement box together with the displacement box, as can be seen in FIG. 2, they form an equilateral triangle with rounded corners in cross section.
- This closed form is therefore very suitable both for penetration into the ground and for the production of a pile made of concrete or the like, which has approximately the same cross section.
- a material feed pipe 18 running parallel to the vibrating pipes 10 is provided in the middle, which ends at the bottom in an opening 20 and has a feed line 22 at the top.
- the displacement box 16 has at its lower end approximately in the region of the tips 12 of the vibrating tubes 10 sliding surfaces 24 converging obliquely downwards, which form an opening 26 directed downwards.
- the opening 26 is located so that concrete or the like introduced into the material supply pipe 18 under pressure can flow out through the opening into the ground, while the device is pulled up again after the end of the lowering, so that the material completely clears the released cavity in the ground fills out.
- Each vibrating tube is interrupted in its upper area in a manner known per se via a hard elastic coupling member 32 which largely dampens the vibrations generated by the vibrating motor, not shown, in the lower part of the vibrating tube in the section of the vibrating tube 10 located above the coupling member 32.
- These upper sections of the vibrating tubes are connected to one another by a rigid support part 28, while those subjected to the vibrating vibrations lower sections of the vibrating tubes 10 are connected to each other and to the displacement box 16 by a hard elastic connecting member 30.
- the connecting member 30 is preferably attached approximately at the level of the amplitude of the vibrating tube vibrations.
- the vibrating tubes 10 are held stably in the recesses 14 of the displacement box 16 by the carrier part 28 and the connecting member 30.
- FIGS. 5 and 6 has four parallel vibrating tubes 10, which are arranged in corresponding recesses 14 ′′ of a displacement box 16 ′′ and, with this, result in an approximately square overall cross section of the device with rounded corners formed by the vibrating tubes 10.
- This device accordingly produces a very stable concrete pile with an approximately square cross section.
- the inclined sliding surfaces 24 ′′ form a substantially larger opening 26 ′′ at the lower end of the displacement box 16 ′′, through which the material feed tube 18 exits and protrudes somewhat.
- the opening 26 ′′ is essentially square and can be closed in the closed position shown in the left half of FIG. 6 by a likewise slidable closure slide 44 which can be displaced in the axial direction of the device, ie parallel to the vibrating tubes 10.
- the plate-shaped closure slide 44 has a central opening 46 which comprises the material feed pipe 30.
- the piston rods 48 are pivotally articulated by two vertically acting hydraulic cylinders, which in turn are pivotally mounted at their upper ends on a holding bridge 52 welded tightly in the displacement box 16 ′′.
- the holding bridge 52 carries a central ring 54 which surrounds the material feed pipe 18.
- the hydraulic cylinders 50 are extended, thereby closing the opening 26 ′′.
- the soil located inside the displacement box 16 '' is therefore taken upwards when the device is pulled, so that not only the lowering of the device due to the penetration of the soil into the displacement box 16 '' is opposed to less resistance, but also the filling the resulting cavity with concrete or the like. Is significantly facilitated.
- the displacement box 16 ′′ extends essentially over the entire height of the vibrating tubes 10.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.
Eine Vorrichtung dieser Art ist aus der DE-OS 2 236 901 bekannt. Diese bekannte Vorrichtung verwendet jedoch mehr als ein Rüttelrohr an einem gemeinsamen Mäkler nur für den Fall, daß die Rüttelrohre in Linie nebeneinander angeordnet sind und zur Herstellung einer schmalen Schlitzwand im Erdreich dienen. Für die Herstellung eines Pfahles im Erdreich kann bei der bekannten Vorrichtung nur ein einziges Rüttelrohr angewendet werden. Zur besseren Führung im Erdreich können zu beiden Seiten der Spitze des Rüttelrohrs Führungsschwerter angeordnet sein. Ein derartiges Rüttelrohr hat einen Durchmesser von etwa 40 cm. Dieser Durchmesser kann nicht wesentlich vergrößert werden, da er erfahrungsgemäß für das Eindringen des Rüttelrohrs ein Optimum darstellt. Die Eindringgeschwindigkeit eines Rüttelrohrs in den Untergrund ist um so größer, je kleiner sein Durchmesser, je größer seine Rüttelfrequenz und je größer seine Schwingungsamplitude ist.A device of this type is known from DE-OS 2 236 901. However, this known device uses more than one vibrating tube on a common leader only in the event that the vibrating tubes are arranged in a line next to one another and are used to produce a narrow diaphragm wall in the ground. For the manufacture of a pile in the ground, only a single vibrating tube can be used in the known device. Guide blades can be arranged on both sides of the tip of the vibrating tube for better guidance in the ground. Such a vibrating tube has a diameter of approximately 40 cm. This diameter cannot be increased significantly, since experience has shown that it is the optimum for penetration of the vibrating tube. The speed of penetration of a vibrating tube into the ground is greater, the smaller its diameter, the greater its vibrating frequency and the greater its vibration amplitude.
Das Innere des hohlen Rüttelrohrs wird bei der bekannten Vorrichtung als Betonzuführrohr verwendet, das unten an der Spitze des Rüttelrohres offen ist. Das Betonzuführrohr wird während des Eindringens der Vorrichtung in das Erdreich mit unter Druck stehendem Beton oder dgl. gefüllt, so daß kein Erdreich in das offene Ende des Zuführrohrs eindringen kann.The inside of the hollow vibrating tube is used in the known device as a concrete feed tube, which is open at the bottom of the vibrating tube. The concrete feed pipe is filled with pressurized concrete or the like during the penetration of the device into the ground so that no ground can penetrate into the open end of the feed pipe.
Pfähle mit größerem Durchmesser werden nach dem Stand der Technik entweder so eingebracht, daß sie außerhalb des Erdreichs fertig gegossen und ausgehärtet und sodann durch Schlaghämmer mit großer Geräuschentwicklung und Erschütterungswirkung in das Erdreich eingeschlagen werden oder indem vorher mit einem Bohrgerät das Erdreich langwierig herausgebohrt und anschließend der Beton in den entstandenen Hohlraum verfüllt wird.According to the prior art, piles with a larger diameter are either introduced in such a way that they are poured and hardened outside of the ground and then hammered into the ground by means of impact hammers with a high level of noise and vibration, or by previously drilling out the ground with a drill and then subsequently Concrete is filled into the resulting cavity.
Durch die Erfindung soll eine Vorrichtung der eingangs genannten Art so verbessert werden, daß Pfähle mit den Querschnitt eines Rüttelrohrs von 40 cm Durchmesser wesentlich übersteigenden, geschlossenen Querschnitten, deren kleinste Querabmessung ≥ etwa 40 cm ist, in einfacher und schneller Weise in das Erdreich eingebracht werden können.The invention is intended to improve a device of the type mentioned at the outset so that piles with the cross-section of a vibrating tube of 40 cm in diameter substantially exceeding closed cross-sections, the smallest cross dimension of which is ≥ approximately 40 cm, are introduced into the ground in a simple and rapid manner can.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved according to the invention by the characterizing features of claim 1.
Die hartelastisch mit dem Verdrängerkasten verbundenen Rüttelrohre versetzen die ganze Vorrichtung derart in Schwingungen, daß sie wirkungsvoll in das Erdreich eindringen kann. Zur Verdrängung des Erdreichs wirken die schrägen Gleitflächen des Verdrängerkastens mit den Spitzen der Rüttelrohre zusammen. Die geschlossene Querschnittsform der Vorrichtung sorgt für eine günstige Verdichtung des verdrängten Erdreichs. Nach dem Absenken der Vorrichtung in das Erdreich wird wie bei den bekannten Vorrichtungen Beton oder ähnliches aushärtbares Injektionsmaterial in den beim Ziehen der Vorrichtung frei werdenden Hohlraum des Erdreichs durch das Materialzuführrohr eingeleitet, so daß der Hohlraum vollständig ausgefüllt wird. Dadurch ergibt sich ein Pfahl aus Beton oder dgl. mit erheblich stärkeren Abmessungen, als sie mit bekannten Vorrichtungen mit einem einzigen rohrförmigen Rüttler erzielbar sind.The vibrating tubes, which are rigidly connected to the displacement box, cause the entire device to vibrate in such a way that it can effectively penetrate the soil. The oblique sliding surfaces of the displacement box interact with the tips of the vibrating tubes to displace the soil. The closed cross-sectional shape of the device ensures favorable compaction of the displaced soil. After lowering the device in that Soil, as in the known devices, concrete or similar hardenable injection material is introduced into the cavity of the soil that is released when the device is pulled, through the material feed pipe, so that the cavity is completely filled. This results in a pile of concrete or the like. With considerably larger dimensions than can be achieved with known devices with a single tubular vibrator.
Der Verdrängerkasten besteht vorzugsweise aus hohlem Stahlblech oder dergleichen. Als besonders zweckmäßig hat sich ein Querschnittsverhältnis herausgestellt, bei dem der Querschnitt des Verdrängerkastens sich zur Summe der Querschnitte aller Rüttelrohre etwa wie 1:2 verhält, wobei jedoch dieses Verhältnis für die erfindungsgemäße Vorrichtung nicht zwingend ist.The displacement box is preferably made of hollow steel sheet or the like. A cross-sectional ratio in which the cross-section of the displacement box is approximately 1: 2 to the sum of the cross-sections of all vibrating tubes has proven to be particularly expedient, although this ratio is not essential for the device according to the invention.
Besonders vorteilhaft sind gemäß Anspruch 2 ausgebildete Ausführungsformen mit zwei, drei oder vier Rüttelrohren.Embodiments with two, three or four vibrating tubes are particularly advantageous.
Ein Materialzuführrohr ist gemäß Anspruch 3 vorzugsweise im Verdrängerkasten angeordnet, wo es gegen Beschädigung am besten geschützt ist und mündet unten nahe einer Öffnung des Verdrängerkastens. Wenn vermieden werden soll, daß Erdreich in den Verdrängerkasten eindringt, so können die beiden Öffnungen auch zusammenfallen.A material feed pipe is preferably arranged according to claim 3 in the displacement box, where it is best protected against damage and opens at the bottom near an opening of the displacement box. If it is to be avoided that soil penetrates into the displacement box, the two openings can also coincide.
Die Ansprüche 4 bis 6 betreffen vorteilhafte Ausgestaltungen von Einrichtungen zur Festlegung der Teile der Vorrichtung aneinander sowie an dem sie tragenden Mäkler.Claims 4 to 6 relate to advantageous configurations of devices for fixing the parts of the device to one another and to the leader carrying them.
Bei bestimmten Zusammensetzungen des Erdreichs kann es sich als hilfreich erweisen, eine größere Öffnung am unteren Ende des Verdrängerkastens vorzusehen, durch die das Erdreich beim Absenken der Vorrichtung eindringen kann. In vorteilhafter Weiterbildung der Erfindung nach Anspruch 7 kann die Öffnung des Verdrängerkastens nach Aufnahme des Erdreichs verschlossen und somit das eingedrungene Erdreich mit der Vorrichtung herausgezogen werden. Zu diesem Zweck wird dem Verdrängerkasten eine größere Höhe erteilt, so daß er sich über die ganze Länge der Rüttelrohre erstreckt.With certain soil compositions, it may be helpful to provide a larger opening at the bottom of the displacement box through which the soil can pass can penetrate when lowering the device. In an advantageous development of the invention according to claim 7, the opening of the displacement box can be closed after taking up the soil and thus the penetrated soil can be pulled out with the device. For this purpose, the displacement box is given a greater height so that it extends over the entire length of the vibrating tubes.

Bei dem in den Figuren 1 bis 4 dargestellten Ausführungsbeispiel sind drei parallele Rüttelrohre 10 mit konischen Spitzen 12 an ihren unteren Enden vorgesehen. Die Rüttelrohre 10 sind in etwa halbkreisförmigen Querschnitt aufweisenden Ausnehmungen eines aus hohlem Stahlblech bestehenden gemeinsamen Verdrängerkastens 16 angeordnet. In dieser Anordnung bilden sie zusammen mit dem Verdrängerkasten, wie aus Fig. 2 ersichtlich ist, im Querschnitt etwa ein gleichseitiges Dreieck mit abgerundeten Ecken. Diese geschlossene Form eignet sich daher sehr gut sowohl für das Eindringen in das Erdreich als auch für die Anfertigung eines Pfahles aus Beton oder dergl., der etwa den gleichen Querschnitt besitzt.In the embodiment shown in Figures 1 to 4 three parallel
Im Inneren des Verdrängerkastens 16 ist in dessen Mitte ein parallel zu den Rüttelrohren 10 verlaufendes Materialzuführrohr 18 vorgesehen, das unten in einer Öffnung 20 endet und oben eine Zuleitung 22 aufweist. Der Verdrängerkasten 16 weist an seinem unteren Ende etwa im Bereich der Spitzen 12 der Rüttelrohre 10 schräg nach unten zusammenlaufende Gleitflächen 24 auf, die eine nach unten gerichtete Öffnung 26 bilden. Die Öffnung 26 ist so gelegen, daß unter Druck im Materialzuführrohr 18 eingeleiteter Beton oder dergl. durch die Öffnung ins Erdreich ausströmen kann, während die Vorrichtung nach dem Ende des Absenkens wieder nach oben gezogen wird, so daß das Material den freigegebenen Hohlraum im Erdreich vollständig ausfüllt.In the interior of the
Jedes Rüttelrohr ist in seinem oberen Bereich in an sich bekannter Weise über ein hartelastisches Kupplungsglied 32 unterbrochen, das die durch den nicht gezeigten Rüttelmotor im unteren Teil des Rüttelrohrs erzeugten Schwingungen im oberhalb des Kupplungsgliedes 32 gelegenen Abschnitt des Rüttelrohrs 10 weitgehend abdämpft. Diese oberen Abschnitte der Rüttelrohre sind durch einen starren Trägerteil 28 miteinander verbunden, während die den Rüttelschwingungen unterworfenen unteren Abschnitte der Rüttelrohre 10 durch ein hartelastisches Verbindungsglied 30 untereinander sowie mit dem Verdrängerkasten 16 verbunden sind. Das Verbindungsglied 30 ist vorzugszweise etwa in Höhe des Amplitudenminimuns der Rüttelrohrschwingungen angebracht. Durch den Trägerteil 28 und das Verbindungsglied 30 werden die Rüttelrohre 10 stabil in den Ausnehmungen 14 des Verdrängerkastens 16 gehalten.Each vibrating tube is interrupted in its upper area in a manner known per se via a hard
Bei der in Figur 4 gezeigten einfacheren Ausführungsform sind nur zwei Rüttelrohre 10 in im Querschnitt kreisbogenförmigen Aussparungen 14' eines Verdrängerkastens 16' angeordnet, wodurch sich ein im wesentlichen etwa langrechteckiger Gesamtquerschnitt der Vorrichtung mit durch die Rüttelrohre 10 gebildeten abgerundeten Ecken ergibt. Im übrigen kann diese Ausführungsform analog zu der in den Figuren 1 bis 3 dargestellten Ausführungsform ausgebildet sein.In the simpler embodiment shown in FIG. 4, only two vibrating
Die in den Figuren 5 und 6 dargestellte Ausführungsform schließlich weist vier parallele Rüttelrohre 10 auf, die in entsprechenden Aussparungen 14'' eines Verdrängerkastens 16'' angeordnet sind und mit diesem einen etwa quadratischen Gesamtquerschnitt der Vorrichtung mit durch die Rüttelrohre 10 gebildeten abgerundeten Ecken ergeben. Durch diese Vorrichtung wird demnach ein sehr stabiler Betonpfahl mit etwa quadratischem Querschnitt erzeugt.Finally, the embodiment shown in FIGS. 5 and 6 has four parallel vibrating
Bei dieser Ausführungsform mit verhältnismäßig großem Querschnitt ist es unter Umständen zweckmäßig, beim Absenken der Vorrichtung einen Teil des verdrängten Erdreichs in das Innere des Verdrängerkastens aufzunehmen und beim Ziehen der Vorrichtung aus dem Bohrloch herauszuheben. Zu diesem Zweck bilden die schrägen Gleitflächen 24'' am unteren Ende des Verdrängerkastens 16'' eine wesentlich größere Öffnung 26'', durch die das Materialzuführrohr 18 austritt und etwas übersteht. Die Öffnung 26'' ist im wesentlichen quadratisch und kann durch einen ebenfalls quadratischen und in Axialrichtung der Vorrichtung, d.h. parallel zu den Rüttelrohren 10, verschiebbaren Verschlußschieber 44 in dessen in der linken Hälfte der Figur 6 gezeigten Verschlußstellung verschlossen werden. Der plattenförmige Verschlußschieber 44 besitzt eine mittige Öffnung 46, welche das Materialzuführrohr 30 umfaßt. An der Oberseite des Verschlußschiebers 44 sind die Kolbenstangen 48 von zwei vertikal wirkenden Hydraulikzylindern schwenkbar angelenkt, die ihrerseits an ihren oberen Enden an einer im Verdrängerkasten 16'' festgeschweißten Haltebrücke 52 schwenkbar gelagert sind. Die Haltebrücke 52 trägt einen mittigen Ring 54, welcher das Materialzuführrohr 18 umschließt. Im ausgefahrenen Zustand der Hydraulikzylinder 50 wird der Verschlußschieber 44 in die in der linken Hälfte von Fig. 6 gezeigte Verschlußstellung bewegt, und beim Einziehen der Hydraulikzylinder 50 gelangt der Verschlußschieber in die in der rechten Hälfte von Figur 6 angedeutete Öffnungsstellung 44'. In dieser Öffnungsstellung kann beim Absenken der Vorrichtung Erdreich gemäß dem Pfeil 56 ins Innere des Verdrängerkastens 16'' eindringen. Am untersten Punkt der Absenkbewegung der Vorrichtung werden die Hydraulikzylinder 50 ausgefahren und dadurch die Öffnung 26'' verschlossen. Das im Innern des Verdrängerkastens 16'' befindliche Erdreich wird daher beim Ziehen der Vorrichtung mit nach oben genommen, so daß nicht nur dem Absenken der Vorrichtung infolge des Eindringens des Erdreichs in den Verdrängerkasten 16'' ein geringerer Widerstand entgegengesetzt wird, sondern auch das Befüllen des entstandenen Hohlraums mit Beton oder dgl. wesentlich erleichtert wird. In nicht gezeigter Weise erstreckt sich bei dieser Ausführungsform der Verdrängerkasten 16'' im wesentlichen über die ganze Höhe der Rüttelrohre 10.In this embodiment with a relatively large cross-section, it may be expedient to absorb part of the displaced soil into the interior of the displacement box when lowering the device and to lift it out of the borehole when pulling the device. For this purpose, the inclined sliding
