Description

GEBIET DER ERFINDUNGFIELD OF THE INVENTION

Die vorliegende Erfindung betrifft ein Verfahren zum senkrechten Verlegen eines Rohres, vorzugsweise eines Stahlrohres in einen Untergrund, vorzugsweise erdigen Untergrund, wobei das Rohr zunächst senkrecht ausgerichtet über einem Verlegeort positioniert wird und mittels eines vorzugsweise hydraulisch angetriebenen Schlagbolzens einer Schlagvorrichtung sich wiederholende Kraftimpulse auf eine vom Untergrund entfernte Stirnseite des Rohres abgegeben werden, um dieses in den Untergrund zu rammen, gemäß dem Oberbegriff des Anspruchs 1, sowie eine entsprechende Schlagvorrichtung und eine entsprechende Schlagplatte.The present invention relates to a method for vertically laying a pipe, preferably a steel pipe in a subsoil, preferably earthy ground, wherein the tube is first positioned vertically aligned over a laying location and by means of a preferably hydraulically driven firing pin of a percussion repeating force pulses to one from the ground remote end face of the tube are discharged to ram this in the ground, according to the preamble of claim 1, and a corresponding impact device and a corresponding impact plate.

STAND DER TECHNIKSTATE OF THE ART

Senkrecht im Untergrund verlegte Rohre dienen oft als Basis für Fundamente oberirdischer Bauten. Ein großes Anwendungsgebiet betrifft Schallschutzwände, welche in der Regel aus plattenförmigen Schallschutzelementen bestehen, die zwischen vertikal aus dem Boden ragenden Trägern angeordnet und an diesen befestigt sind. Um eine sichere Verankerung der Träger zu gewährleisten, werden diese in zuvor senkrecht im Boden verlegte Rohre eingeführt. Danach werden die Rohre mit Beton ausgegossen.Vertical pipes routed underground often serve as the basis for foundations above ground. A large field of application relates to soundproof walls, which usually consist of plate-shaped soundproofing elements which are arranged between vertically projecting from the ground carriers and fixed thereto. To ensure a secure anchoring of the carrier, they are introduced into previously laid vertically in the ground pipes. Then the pipes are poured out with concrete.

Bislang erfolgte das Verlegen der Rohre im Boden mittels Rütteltechnik. Dabei kommen Rüttelvorrichtungen zum Einsatz, die über Unwucht gelagerte Schwungelemente, die unter erheblichen Energieaufwand bewegt werden, die Rohre senkrecht in den Boden treiben. Problematisch dabei ist einerseits die Positionierung der Rohre, die oft nur sehr ungenau erfolgen kann.So far, the laying of the pipes in the ground by means of vibrating technique. It vibrating devices are used, the unbalance mounted flywheel elements, which are moved under considerable energy expenditure, drive the pipes vertically into the ground. The problem here is the one hand, the positioning of the tubes, which can often be done only very inaccurate.

Das weit größere Problem bei diesem bekannten Verfahren ist allerdings die im Zuge des Rüttelvorgangs stattfindende Verdichtung des Untergrunds, wodurch sich der Verlegevorgang zusätzlich erschwert und mit fortschreitender Dauer des Verlegevorgangs der zum Verlegen erforderliche Kraftaufwand erhöht werden muss.The far greater problem with this known method, however, is the compression of the substrate taking place in the course of the shaking process, which additionally adds to the laying process difficult and must be increased with progressive duration of the installation process required for laying force.

Es sind bereits Verfahren bekannt, siehe hierzu etwa die DE 29 00 221 A1 oder die DE 197 34 966 A1 , bei welchem das Verdichten des Untergrundes beim Verlegevorgang weitgehend vermieden wird und der erforderliche Energieaufwand geringer als bei herkömmlichen Verfahren ist. Die DE 29 00 221 A1 zeigt eine druckmittelgetriebene Rammvorrichtung, die ein Gehäuse aufweist, in welchem ein Schlagkörper verschiebbar geführt ist und das sich auf eine Schlagübertragungsvorrichtung 11 abstützt, die wiederum auf einem Rammteil 10, einem senkrecht angeordneten Rohr, aufliegt.There are already known methods, see about this DE 29 00 221 A1 or the DE 197 34 966 A1 , in which the compaction of the substrate during the laying process is largely avoided and the required energy consumption is less than in conventional methods. The DE 29 00 221 A1 shows a pressure-driven ram device having a housing in which a striking body is slidably guided and which is supported on a shock transmission device 11, which in turn rests on a ram part 10, a vertically arranged tube.

Es ist eine Aufgabe der vorliegenden Erfindung, ein Verfahren zum senkrechten Verlegen eines Rohres, vorzugsweise eines Stahlrohres, in einen Untergrund vorzuschlagen, mit welchem ein kostengünstiger modularer Aufbau der Schlagvorrichtung und ein Anbringen an diversen Baumaschinen ermöglicht wird.It is an object of the present invention to provide a method for vertically laying a pipe, preferably a steel pipe, in a substrate, with which a cost-effective modular construction of the impact device and attachment to various construction machines is possible.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Erfindungsgemäß wird diese Aufgabe beim Verfahren nach Anspruch 1, wonach ein Rohr zunächst senkrecht ausgerichtet über einem Verlegeort positioniert wird und mittels eines vorzugsweise hydraulisch angetriebenen Schlagbolzens einer Schlagvorrichtung sich wiederholende Kraftimpulse auf eine vom Untergrund entfernte Stirnseite des Rohres abgegeben werden, um dieses in den Untergrund zu rammen, dadurch gelöst, dass dessen senkrechte Positionierung über dem Verlegeort durch Aufhängen des Rohres an der Schlagvorrichtung erfolgt. Dadurch kann die Verlegung des Rohres besonders einfach gestaltet werden, die ungewollte Verdichtung des Untergrunds wird durch das Verfahren nach Anspruch 1 ohnehin vermieden. Darüber hinaus ist der mechanische Aufbau der Schlagvorrichtung kostengünstig, wartungsarm und robust. Auch ein zeiteffizienter Verlegungsvorgang ist durch das Verfahren möglich.According to the invention, this object is achieved in the method according to claim 1, after which a tube is first positioned vertically aligned above a laying location and repetitive force pulses are delivered to a remote from the ground end of the tube by means of a preferably hydraulically driven firing pin a percussion device to this in the underground rammed, solved by the fact that its vertical positioning over the installation site is done by hanging the tube to the impact device. As a result, the laying of the pipe can be made particularly simple, the unwanted compression of the substrate is avoided anyway by the method according to claim 1. In addition, the mechanical structure of the impact device is inexpensive, low maintenance and robust. A time-efficient relocation process is also possible by the method.

Die Schlagvorrichtung umfasst dabei in einer bevorzugten Ausführungsform eine in einem Gehäuse angeordnete, vorzugsweise hydraulisch arbeitende Antriebsvorrichtung, die einen in dem Gehäuse linear beweglich gelagerten Schlagbolzen antreibt, sowie eine am Gehäuse befestigte, vorzugsweise aufgehängte Schlagplatte und der Schlagbolzen ist von einer die Schlagplatte nicht kontaktierenden Position in eine die Schlagplatte kontaktierende Position außerhalb des Gehäuses bewegbar und umgekehrt. Hierdurch ist eine kompakte modulare Ausführungsvariante der Schlagvorrichtung gegeben, die für eine rasche Montage an einer Baumaschine wie beispielsweise einem Bagger oder einem ähnlichen Nutzfahrzeug geeignet ist.The impact device comprises in a preferred embodiment, arranged in a housing, preferably hydraulically operating drive device which drives a linearly movably mounted in the housing firing pin, and attached to the housing, preferably suspended impact plate and the firing pin is of a striking plate not contacting position in a beat-contacting position outside the housing movable and vice versa. As a result, a compact modular design variant of the impact device is given, which is suitable for rapid installation on a construction machine such as an excavator or a similar commercial vehicle.

Um die sich wiederholenden Kraftimpulse des Schlagbolzens auf das Rohr zu übertragen, ist es weiters vorgesehen, dass die Schlagplatte zumindest in der den Schlagbolzen kontaktierenden Position die vom Untergrund entfernte Stirnseite des Rohres kontaktiert.In order to transmit the repetitive force impulses of the firing pin to the tube, it is further provided that the impact plate, at least in the firing pin contacting position contacted the remote from the ground end face of the tube.

Die Schlagplatte der Schlagvorrichtung weist einen im wesentlichen zylindrischen Grundkörper auf, mit einer ersten, dem Schlagbolzen abgewandten Stirnseite sowie einer zweiten, einer Kontaktfläche des Schlagbolzens zugewandten Stirnseite, wobei an der zweiten Stirnseite eine, vorzugsweise in Form und Abmessungen an die Kontaktfläche angepasste Vertiefung vorgesehen ist. Die Vertiefung ermöglicht eine gleichmäßige Kraftverteilung innerhalb der Schlagplatte.The impact plate of the impact device has a substantially cylindrical base body, with a first end face facing away from the firing pin and a second end face facing a contact surface of the firing pin, wherein a recess, preferably adapted in shape and dimensions to the contact surface, is provided on the second end face , The recess allows a uniform force distribution within the striking plate.

Um die Lage der Schlagplatte bei Kontakt mit dem Rohr zu fixieren, kann vorgesehen sein, dass diese einen im wesentlichen zylindrischen Grundkörper aufweist, mit einer ersten Stirnseite, an welcher ein zylindrischer, konzentrisch zum zylindrischen Grundkörper angeordneter Absatz mit kleinerem Durchmesser als der Grundkörper ausgebildet ist. Dabei ragt der Absatz in das Rohrinnere und verhindert dadurch ein laterales Abrutschen der Schlagplatte.In order to fix the position of the impact plate in contact with the tube, it can be provided that this has a substantially cylindrical base body, with a first end face on which a cylindrical, arranged concentrically to the cylindrical base body paragraph is formed with a smaller diameter than the main body , In this case, the paragraph protrudes into the tube interior, thereby preventing lateral slipping of the impact plate.

Damit die Schlagplatte für die Anbringung bei Rohren mit unterschiedlichen Innendurchmesser geeignet ist, ist es darüber hinaus in einer besonders bevorzugten Ausführungsvariante vorgesehen, das die Schlagplatte einen im Wesentlichen zylindrischen Grundkörper aufweist, mit einer ersten Stirnseite, an welcher mehrere zylindrische, konzentrisch zum zylindrischen Grundkörper angeordnete Absätze mit jeweils geringerem Durchmesser als der Grundkörper ausgebildet sind, wobei die mehreren Absätze zueinander verschiedene Durchmesser aufweisen und die Durchmesser der mehreren Absätze mit zunehmender Entfernung derselben vom Grundkörper kleiner werden.In order that the striking plate is suitable for attachment to pipes with different inner diameters, it is also provided in a particularly preferred embodiment variant, which the striking plate is a substantially cylindrical Base body has, with a first end face on which a plurality of cylindrical, arranged concentrically to the cylindrical base body heels each having a smaller diameter than the main body are formed, wherein the plurality of paragraphs have different diameters to each other and the diameter of the plurality of paragraphs with increasing distance thereof from the base body smaller become.

Um einem Verkanten der Schlagplatte mit der vom Untergrund entfernten Stirnseite des Rohres vorzubeugen und ein zentriertes Anbringen der Schlagplatte am Rohr zu erleichtern, schließt die Mantelfläche des einen Absatzes bzw. die jeweiligen Mantelflächen der mehreren Absätze jeweils einen stumpfen Winkel mit der ersten Stirnseite des Grundkörpers ein.In order to prevent tilting of the impact plate with the front side of the tube remote from the substrate and to facilitate a centered attachment of the impact plate on the tube, the lateral surface of the paragraph or the respective lateral surfaces of the several paragraphs includes an obtuse angle with the first end face of the body ,

Zwecks einer möglichst gleichmäßigen Verteilung der an der dem Schlagbolzen zugewandten Stirnseite auftretenden Kräfte weist die Schlagplatte an einer der ersten Stirnseite gegenüberliegenden zweiten Stirnseite eine Vertiefung auf, die zur Aufnahme einer Kontaktfläche eines Schlagbolzens vorgesehen ist.For the purpose of a uniform distribution as possible of the forces occurring at the end face facing the firing pin, the striking plate has a recess on a second end face opposite the first end face, which recess is provided for receiving a contact surface of a firing pin.

Da die Schlagplatte ein hohes Gewicht aufweist, verfügt diese zwecks einfacher Handhabbarkeit über Öffnungen, die das Aufhängen der Schlagplatte mittels Seil- oder anderen Haltelementen ermöglichen. Die Öffnungen sind vorzugsweise als Bohrung ausgeführt. Die Verankerung innerhalb jener kann beispielsweise dadurch erreicht werden, dass die Seil- oder Halteelemente jeweils an einem quer zur Achse der Bohrung liegenden Bolzen befestigt sind. Alternativ kann die Befestigung auch durch durchgängige Öffnungen realisiert werden, deren Durchmesser sich in Richtung der ersten Stirnseite erweitert und dadurch geeignet ist, einen entsprechend geformten Bereich des Seil- oder Halteelements, beispielsweise einen keilförmigen Körper, aufzunehmen und somit an einer Bewegung in Richtung der zweiten Stirnseite gehindert wird.Since the impact plate has a high weight, this has for ease of handling through openings that allow the suspension of the striking plate by means of rope or other holding elements. The openings are preferably designed as a bore. The anchoring within that can for example be achieved by the rope or holding elements are each attached to a transverse to the axis of the bore bolts. Alternatively, the attachment can also be realized by means of through openings whose diameter widens in the direction of the first end face and is therefore suitable for receiving a correspondingly shaped region of the cable or retaining element, for example a wedge-shaped body, and thus for moving in the direction of the second Front side is hindered.

In einer besonders bevorzugten Ausführungsvariante ist die Schlagvorrichtung an einer Baumaschine, beispielsweise einem Bagger oder einem ähnlichen Nutzfahrzeug, angebracht. Hierbei ist die Baumaschine mit einem Chassis und einem daran angeordneten Ausleger ausgestattet, wobei der dem Chassis abgewandte Endbereich des Auslegers durch die Schlagvorrichtung mit einer Schlagplatte gebildet ist.In a particularly preferred embodiment variant, the impact device is attached to a construction machine, for example an excavator or a similar utility vehicle. Here, the construction machine with a chassis and a boom arranged thereon equipped, wherein the chassis facing away from the end region of the boom is formed by the impact device with a striking plate.

Um ein Rohr 1 senkrecht in den Untergrund 2 zu verlegen ist es erfindungsgemäß vorgesehen, das Rohr 1 zunächst über dem Verlegeort 3 senkrecht zu positionieren und mittels des Schlagbolzens 8 sich wiederholende Kraftimpulse auf die Schlagplatte 9 und damit auf die vom Untergrund 2 entfernte Stirnseite des Rohres 5 abzugeben, um dieses in den Untergrund 2 zu rammen. Dabei ist das Rohr 1 mittels eines Verbindungselements 22 an das Gehäuse 6 befestigt, das wiederum mit einer Baumaschine 18 verbunden ist. Die Positionierung des Rohres 1 erfolgt durch eine entsprechende Positionierung des Gehäuses 6, deren Lage wiederum durch die Baumaschine 18 vorgegeben wird. Die senkrechte Ausrichtung des Rohres 1 erfolgt dabei durch die Schwerkraft.To move a pipe 1 vertically into the ground 2, it is inventively provided to first position the pipe 1 above the installation site 3 and by means of the firing pin 8 repetitive force pulses to the striking plate 9 and thus to the remote from the ground 2 front side of the tube 5 to ram this into the ground 2. In this case, the tube 1 is fastened by means of a connecting element 22 to the housing 6, which in turn is connected to a construction machine 18. The positioning of the tube 1 is effected by a corresponding positioning of the housing 6, the position of which is again predetermined by the construction machine 18. The vertical orientation of the tube 1 takes place by gravity.

Die Baumaschine 18 kann einerseits selbständig in der Umgebung bewegt werden, oder auch auf einem Wagon angeordnet sein, um beispielsweise ein Fundament von Lärmschutzwänden, die parallel zu Verkehrsschienen montiert werden sollen, zu errichten. Die Baumaschine 18 verfügt über ein Chassis 19 und einen daran angeordneten Ausleger 20, dessen abgewandter Endbereich 21 durch die Schlagvorrichtung 4 gebildet ist.On the one hand, the construction machine 18 can be moved autonomously in the environment, or it can also be arranged on a wagon in order, for example, to erect a foundation of noise protection walls which are to be mounted parallel to traffic rails. The construction machine 18 has a chassis 19 and a boom 20 arranged thereon, the opposite end region 21 of which is formed by the impact device 4.

Befindet sich das Rohr 1 am Verlegeort 3, so wird die Schlagplatte 9 an die vom Untergrund 2 entfernte Stirnseite 5 des Rohres 1 herangeführt, so dass zumindest einer der Absätze 12,13 in das Innere des Rohres 1 ragt. Dabei ist es bevorzugt aber nicht zwingend vorgesehen, dass die Stirnseite 11 der Schlagplatte 9 auch die Stirnseite 5 des Rohres 1 kontaktiert. Da die Schlagplatte 9 an dem Gehäuse 6 aufgehängt ist, bedarf es zum korrekten Heranführen bzw-Aufsetzen der Schlagplatte 9 auf das Rohr 1 lediglich einer geringen ausrichtenden Kraft, die beispielsweise ein Bauarbeiter aufbringen kann. Der Schlagbolzen 8 befindet sich in einer nichtkontaktierenden Position und wird nun beschleunigt, um in einer kontaktierenden Position auf die Vertiefung 15 der Schlagplatte 9 zu treffen und somit einen Kraftimpuls großflächig auf diese und damit das Rohr 1 zu übertragen. Für den Fall, dass die Schlagplatte 9 zunächst lediglich an die vom Untergrund 2 entfernte Stirnseite 5 des Rohres 1 herangeführt wird, so dass zumindest einer der Absätze 12,13 in das Innere des Rohres 1 ragt, erfolgt auch im Zuge des Auftreffens des Schlagbolzens 8 auf die Schlagplatte 9 auch die Kontaktierung zwischen Schlagplatte 9 und Stirnseite 5 des Rohres 1.If the pipe 1 is located at the laying site 3, then the striking plate 9 is brought to the front 5 of the pipe 1 remote from the base 2 so that at least one of the shoulders 12, 13 projects into the interior of the pipe 1. It is preferred but not necessarily provided that the end face 11 of the striking plate 9 also contacted the end face 5 of the tube 1. Since the striking plate 9 is suspended from the housing 6, it requires the correct introduction or placement of the striking plate 9 on the tube 1 only a small aligning force that can apply, for example, a construction worker. The firing pin 8 is in a non-contacting position and is now accelerated to meet in a contacting position on the recess 15 of the striking plate 9 and thus to transmit a force pulse over a large area on this and thus the tube 1. In the event that the striking plate 9 is initially brought only to the remote from the base 2 front side 5 of the tube 1, so that at least one of the paragraphs 12,13 protrudes into the interior of the tube 1, also takes place in the course of impact of the firing pin 8 on the striking plate 9 and the contact between the impact plate 9 and end face 5 of the tube first

Anschließend wird der Schlagbolzen 8 aus der Vertiefung 15 wieder in eine nichtkontaktierende Position bewegt, die ein erneutes Beschleunigen des Schlagbolzens 8 in die kontaktierende Position ermöglicht. Durch Wiederholung dieses Vorganges wird das Rohr 1 sukzessive in den Untergrund 2 getrieben, bis die gewünschte Endposition erreicht ist. Dabei können die Verbindungselemente 22 bereits gelöst werden, sobald sich das Rohr 1 in einer stabilen Position befindet, die im Allgemeinen bereits vor dem Erreichen der Endposition gegeben ist.Subsequently, the firing pin 8 is moved out of the recess 15 again in a non-contacting position, which allows a re-acceleration of the firing pin 8 in the contacting position. By repeating this process, the tube 1 is successively driven into the ground 2 until the desired end position is reached. In this case, the connecting elements 22 can already be released as soon as the tube 1 is in a stable position, which is generally already given before reaching the end position.
