Description

Die Erfindung betrifft eine Rohrtragbohle für eine kombinierte Spundwand, deren Füllbohlen von Profilbohlen gebildet werden.The invention relates to a pipe support screed for a combined sheet pile wall, the filling screeds of which are formed by profiled screeds.

Für Kaimauern und andere Flächentragwerke, die bei hohen Geländesprüngen die waagerecht wirkenden Erd- und Wasserdrücke aufnehmen, werden kombinierte Spundwände verwendet, die aus Tragbohlen und Füllbohlen bestehen. Die Tragbohlen haben im Querschnitt ein Doppel-T-Profil oder ein Kastenprofil mit hohem Widerstandsmoment. Sie sind im seitlichen Abstand voneinander angeordnet und in erster Linie dazu bestimmt, die Biegemomente aus den Horizontal- und Vertikallasten aufzunehmen. Der Zwischenraum zwischen den Tragbohlen wird durch Füllbohlen ausgefüllt, für die in der Regel einfache Stahlspundbohlen mit Kasten- oder Wellenprofil bekannter Bauart verwendet werden.Combined sheet piling is used for quay walls and other tensile structures that absorb the horizontal earth and water pressures when the terrain is high. The crossbeams have a double T profile or a box profile with a high section modulus. They are arranged at a lateral distance from one another and are primarily intended to absorb the bending moments from the horizontal and vertical loads. The space between the supporting screeds is filled with filling screeds, for which simple steel sheet piles with a box or corrugated profile of known design are generally used.

Da das Widerstandsmoment der Walzprofilträger zur Aufnahme sehr hoher Horizontalkräfte nicht ausreicht und die bekannten Kastenprofilträger aus mehreren Platten und Spundbohlen zusammengeschweißt werden müssen, wodurch hohe Kosten verursacht werden und nur verhältnismäßig labile Tragbohlen entstehen, ist es auch bereits bekannt, als Tragbohlen spiralgeschweißte Großrohre zu verwenden (Handbuch für Hafenbau und Umschlagtechnik, Bd. XXX, 1985, S. 11 und 12). Für den Anschluß der zwischen diesen als Rohre ausgebildeten Tragbohlen angeordneten Füllbohlen sind auf die Außenseite der Rohrwandung Spundwandschlösser aufgeschweißt, in die nach dem Niederbringen der Rohrtragbohlen die anschließenden Füllbohlen eingeführt und ebenfalls niedergebracht werden.Since the section modulus of the rolled section girders is not sufficient to absorb very high horizontal forces and the known box section girders have to be welded together from several plates and sheet piles, which causes high costs and only relatively unstable supporting planks, it is already known to use spiral-welded large pipes as supporting planks ( Handbuch für Hafenbau und Umschlagtechnik, Vol. XXX, 1985, p. 11 and 12). For the connection of the pipes formed between them Filling screeds arranged on supporting screeds are welded to the outside of the pipe wall sheet pile locks, into which the subsequent screeds are inserted and also brought down after the pipe supporting screeds have been brought down.

Allen bekannten Tragbohlen ist gemeinsam, daß sie nur in den Boden eingeschlagen oder eingerüttelt werden können, wobei namentlich bei den als Rohren ausgebildeten Tragbohlen die Gefahr besteht, daß sie sich um einen gewissen Winkelbetrag um ihre Längsachse drehen und die außen angebrachten Schlösser sich nicht mehr in der gewünschten, richtigen Lage befinden, die für den Anschluß der Füllbohlen notwendig ist. Vor allem aber ist die Lärmbelästigung beim Rammen der Tragbohlen und die Schwingungsbelästigung beim Einrütteln bedeutend und kann ihrer schädlichen Einflüsse auf die Umwelt und benachbarte Gebäude wegen oft nicht zugelassen werden.All known trusses have in common that they can only be hammered or shaken into the ground, whereby there is a particular risk in the case of the trusses designed as tubes that they rotate by a certain angle about their longitudinal axis and the locks on the outside are no longer in the desired, correct position, which is necessary for the connection of the filling planks. Above all, however, the noise nuisance when ramming the screed and the vibration nuisance when shaking is significant and can often not be permitted because of its harmful effects on the environment and neighboring buildings.

Aufgabe der Erfindung ist es deshalb, eine Tragbohle mit kreisrundem Querschnitt, die im folgenden immer als "Rohrtragbohle" bezeichnet wird, zu schaffen, die ohne Lärmbelästigung und ohne das Einleiten von Schwingungen und Erschütterungen in den Boden niedergebracht werden kann, die verhältnismäßig einfach und kostengünstig herzustellen ist und eine genaue Ausrichtung der Schlösser in die Flucht der Füllbohlen ermöglicht.The object of the invention is therefore to provide a support screed with a circular cross section, which is always referred to below as "pipe support screed", which can be brought down in the ground without noise and without introducing vibrations and vibrations, which is relatively simple and inexpensive is to be produced and enables the locks to be precisely aligned in the alignment of the filling planks.

Diese Aufgabe wird mit der Erfidung dadurch gelöst, daß die Schlösser für den Anschluß der Füllbohlen auf der Innenseite der Rohrwandung angeordnet sind und daß die Rohrwandung im Bereich eines jeden Schlosses einen Schlitz aufweist.This object is achieved with the invention in that the locks for connecting the filling planks are arranged on the inside of the tube wall and in that the tube wall has a slot in the area of each lock.

Diese Ausgestaltung hat den Vorteil, daß der kreisrunde Außenumfang der Rohrtragbohle nicht durch vorspringende Schloßleisten gestört wird und es hierdurch möglich ist, die Rohrtragbohle wie einen Bohrpfahl nach den für solche Bohrpfähle üblichen Methoden in den Boden einzubohren. Hierbei können die Rohrtragbohlen mit einem Kraftdrehkopf oder einer Verrohrungsmaschine abgeteuft werden. Der Einbau kann auch mit Rammhämmern und Vibratoren erfolgen. Gleichzeitig ist es möglich, das Erdreich im Inneren der Rohrtragbohle beim Niederbringen ständig zu entfernen und ggf. unter dem unteren Schneidenrand angetroffenes Gestein, wie große Findlinge u.dgl., auszuräumen oder zu zertrümmern. Da die Rohrtragbohle nach der Erfindung beim Niederdrehen im Boden zuverlässig geführt wird und durch Gesteinseinschlüsse unter ihrem unteren Schneidrand nicht abgelenkt werden kann, kann eine fluchtgenaue und senkrechte Anordnung erreicht werden. Außerdem ist es möglich, die Rohrtragbohle in jede gewünschte Richtung um ihre eigene Achse in diejenige Lage zu drehen, in der ihre Schlösser in der Flucht der Füllbohlen liegen, die zwischen ihnen angeordnet werden sollen.This embodiment has the advantage that the circular outer circumference of the tubular support screed is not disturbed by projecting lock strips and it is thereby possible to design the tubular support screed like a bored pile for such Bored piles are conventional methods of drilling into the ground. Here, the pipe support screeds can be sunk with a power turret or a casing machine. The installation can also be done with pile hammers and vibrators. At the same time, it is possible to continuously remove the soil inside the pipe support screed when bringing it down and, if necessary, to clear away or smash rock found under the lower cutting edge, such as large boulders and the like. Since the pipe support screed according to the invention is reliably guided in the ground when it is turned down and cannot be deflected by rock inclusions beneath its lower cutting edge, an accurate and vertical arrangement can be achieved. In addition, it is possible to rotate the pipe support screed in any desired direction about its own axis in the position in which its locks are in alignment with the filling screeds that are to be arranged between them.

Besonders zweckmäßig ist es, wenn sich die SchLLtze nur im oberen Teil der Tragbohlen befinden und die Rohrwandung im Bereich des unteren Randes der Tragbohle geschlossen ist.It is particularly expedient if the bays are only in the upper part of the support screeds and the tube wall in the area of the lower edge of the support screed is closed.

Die Rohrtragbohle hat hierdurch im Bereich ihres unteren Schneidenrandes und noch darüber den vollen Rohrquerschnitt, so daß die beim Niederbringen des Rohres auf dieses ausgeübten Umfangskräfte voll aufgenommen werden können und eine hohe Steifigkeit des Rohres in demjenigen Teil erreicht wird, mit dem das Rohr in den Boden eindringt.The pipe support screed thus has the full pipe cross-section in the area of its lower cutting edge and even above it, so that the circumferential forces exerted on this when the pipe is brought down can be fully absorbed and a high rigidity of the pipe is achieved in the part with which the pipe enters the ground penetrates.

Die Schlösser in der Tragbohle sind zweckmäßig ebenso lang wie die anzuschließenden Füllbohlen, die ja nur so tief in den Boden eindringen müssen, daß der untere Rand genügend eingespannt ist.The locks in the support screed are expediently as long as the filling screeds to be connected, which only have to penetrate so deep into the ground that the lower edge is sufficiently clamped.

Die Schlösser können Kastenschlösser sein, die an den Schlitzrändern angeschweißt sind. Die Schlösser können aber auch jeweils aus einem Eckprofil und angeschweißten Stahl leisten bestehen.The locks can be box locks that are welded to the edges of the slots. The locks can also consist of a corner profile and welded steel strips.

Um eine ausreichende Steifigkeit der Rohrtragbohle in Umfangsrichtung und in Längsrichtung auch dort zu erreichen, wo die Rohrtragbohle im Bereich der Spundwandschlösser geschlitzt ist, ist die Rohrwandung mindestens im Bereich eines jeden Schlitzes durch Stahlprofilträger ausgesteift, die an der Innenseite der Rohrwandung, ggf. auf beiden Seiten des Schlitzes, angeschweißt sind. Für die Aussteifung können I-oder U-Profilträger verwendet werden. Besonders zweckmäßig ist es jedoch, Winkelprofilträger einzusetzen, von denen jeder mit seinen freien Rändern auf beiden Seiten des jeweiligen Rohrschlitzes festgeschweißt ist und das dort angeordnete Schloß umgibt. Die auf die Rohrtragbohle am oberen,Ende ausgeübten Umfangskräfte zum Eindrehen und Niederbringen der Tragbohle werden hierdurch im Bereich der Schlitze durch die eingeschweißten Stahlprofilträger von einem Schlitzrand zum anderen übertragen, so daß die Schloßprofilleisten nicht allein die Umfangskräfte aufnehmen müssen. Hierdurch ist ein Verbiegen oder eine Verformung der in die Schlitze eingeschweißten Schlösser ausgeschlossen und es ist jederzeit möglich, die Füllbohlen ohne Zwängungen in das Schloß einzuführen und später wieder herauszuziehen.In order to achieve sufficient rigidity of the pipe support screed in the circumferential direction and in the longitudinal direction where the pipe support screed is slotted in the area of the sheet piling locks, the pipe wall is braced at least in the area of each slot by steel profile girders, which on the inside of the pipe wall, possibly on both Sides of the slot, are welded. I or U profile beams can be used for the bracing. However, it is particularly expedient to use angle profile supports, each of which is welded with its free edges on both sides of the respective pipe slot and surrounds the lock arranged there. The circumferential forces exerted on the tubular support screed at the upper end for screwing in and bringing down the support screed are thereby transmitted from one slot edge to the other in the area of the slots by the welded-in steel profile supports, so that the lock profile strips do not have to absorb the peripheral forces alone. This prevents bending or deformation of the locks welded into the slots and it is possible at any time to insert the filling planks into the lock without constraints and to pull them out later.

In den Zeichnungen ist mit 10 eine kombinierte Spundwand bezeichnet, die aus mehreren, im seitlichen Abstand voneinander angeordneten Rohrtragbohlen 11 und dazwischen angeordneten Füllbohlen 12 besteht, die bei dem dargestellten Ausführungsbeispiel von drei im Querschnitt trapezförmigen Stahlbohlen gebildet werden, die mit ihren Randschlössern 13 an ihren aneinanderstoßenden Rändern ineinandergreifen. Jede der Rohrtragbohlen besteht aus einem Stahlgroßrohr, das unterschiedliche Durchmesser haben kann und bei dem dargestellten Ausführungsbeispiel aus zwei Halbzylinderschalen 11a und llb besteht, die im unteren Bereich B an ihren Längsrändern miteinander verschweißt sind, so daß sie hier ein geschlossenes Rohr bilden und sich ein durchgehender unterer Schneidrand 14 an der Rohrtragbohle ergibt. Im oberen Teil A bilden die beiden Halbschalen lla und llb mit ihren Längsrändern 15 und 16 Schlitze 17, die in Richtung der Erzeugenden des Rohres verlaufen.In the drawings, 10 denotes a combined sheet pile wall, which consists of a plurality of tubular support planks 11 arranged at a lateral distance from one another and filling planks 12 arranged between them, which in the exemplary embodiment shown are formed by three steel planks which are trapezoidal in cross section and have their edge locks 13 on them interlocking edges. Each of the pipe support planks consists of a large steel pipe, which can have different diameters and, in the exemplary embodiment shown, consists of two half-cylinder shells 11a and 11b which are welded to one another at their longitudinal edges in the lower region B, so that here they form a closed pipe and form a continuous pipe gives lower cutting edge 14 on the pipe support screed. In the upper part A, the two half-shells 11a and 11b with their longitudinal edges 15 and 16 form slots 17 which run in the direction of the generatrix of the tube.

In diesen Schlitzen 17 ist jeweils ein Spundwandschloß angeordnet, das im folgenden einfach als "Schloß" 18 bezeichnet ist. Das Schloß 18 ist derart an den einander gegenüberliegenden Längsrändern 15 und 16 der beiden Rohrhälften lla und llb mit Schweißnähten 19 und 20 angeschweißt, daß es sich auf der Innenseite 21 der Rohrwandung 22 befindet und sich nach außen öffnet. Hierbei schließt das Schloß 18 mit der Außenseite 23 der Rohrwandung 22 der Rohrtragbohle bündig ab, steht also nicht über die Außenseite 23 der Rohrtragbohle vor.In these slots 17 a sheet pile lock is arranged, which is simply referred to as "lock" 18 in the following. The lock 18 is welded to the opposite longitudinal edges 15 and 16 of the two tube halves 11a and 11b with weld seams 19 and 20 in such a way that it is located on the inside 21 of the tube wall 22 and opens outwards. The lock 18 closes here from the outside 23 of the pipe wall 22 of the pipe support screed, ie does not protrude beyond the outside 23 of the pipe support screed.

Bei der in Fig. 4 dargestellten Ausführungsform ist das Schloß 18 ein Kastenschloß, welches aus einem Stück besteht. Bei der in Fig. 5 dargestellten Ausführungsform beteht das Schbß 18 aus einer Eckprofilleiste 18a, die durch eine angeschweißte Stahlleiste 18b zu einem Kastenprofil ergänzt ist, das dann ebenso wie bei dem Ausführungsbeispiel nach Fig. 4 mit Schweißnähten 19 und 20 an den Längsrändern 15 und 16 der Rohrtragbohle festgeschweißt ist.In the embodiment shown in Fig. 4, the lock 18 is a box lock, which consists of one piece. In the embodiment shown in Fig. 5, the butt 18 consists of a corner profile strip 18a, which is supplemented by a welded steel strip 18b to form a box profile, which then, like in the exemplary embodiment according to FIG. 4, with weld seams 19 and 20 on the longitudinal edges 15 and 16 the pipe support beam is welded.

Um eine bessere Steifigkeit der Rohrtragbohle 11 im Bereich der Schlösser 18 zu erreichen und die beim Niederbringen der Rohrtragbohlen auf diese ausgeübten Umfangskräfte in der Rohrwandung 22 sicher von der einen Halbschale lla zur anderen Halbschale llb und umgekehrt weiterzuleiten, ist die Rohrwandung 22 im Bereich der Schlitze 17 durch je einen Winkelprofilträger 24 ausgesteift, der das im Schlitz 17 angeordnete und über die Innenseite 21 der Rohrwandung 22 vorstehende Schloß 18 überdeckt und mit seinen freien Rändern 25 und 26 an der Innenseite 21 der Rohrwandung auf beiden Seiten des Rohrschlitzes 17 mit Schweißnähten 27 und 28 festgeschweißt ist. Anstelle des Winkelprofilträgers 24 könnte auch ein U-Profilträger oder ein Stahlträger mit Hutprofil vorgesehen sein.In order to achieve a better rigidity of the tubular support screed 11 in the area of the locks 18 and to reliably transmit the circumferential forces exerted on the tubular support screeds in the tube wall 22 from one half shell 11a to the other half shell 11b and vice versa, the tube wall 22 is in the area of the slots 17 stiffened by an angle profile beam 24, which covers the lock 18 arranged in the slot 17 and protrudes beyond the inside 21 of the tube wall 22 and with its free edges 25 and 26 on the inside 21 of the tube wall on both sides of the tube slot 17 with weld seams 27 and 28 is welded. Instead of the angle section support 24, a U-section support or a steel support with a hat profile could also be provided.

Beim Herstellen der kombinierten Spundwand wird zweckmäßig so vorgegangen, daß zunächst die Rohrtragbohlen 11 bis auf die erforderliche Tiefe T1 mit einem Kraftdrehkopf oder mit einer Verrohrungsmaschine, Rammhämmern und Vibratoren niedergebracht werden. Hierbei werden die Rohre um ihre Längsachse hin- und herbewegt, während gleichzeitig auf die Rohre ein hoher Axialdruck ausgeübt wird, wie dies beim Niederbringen von Bohrpfählen an sich bekannt ist. Beim Niederbringen kann der Boden im Inneren des Rohres entfernt werden, falls sich dies als notwendig oder zweckmäßig erweist. Außerdem ist es möglich, im Inneren der Schlösser 18 eine Fülleiste anzuordnen, die ein Eindringen von Boden ins Innere des Schlosses verhindert und die wieder herausgezogen werden kann, wenn die Rohrtragbohle 11 die gewünschte Lage erreicht hat.In the manufacture of the combined sheet pile wall, it is expedient to proceed in such a way that the pipe support screeds 11 are first brought down to the required depth T 1 with a power turret or with a piping machine, pile hammers and vibrators. Here, the pipes are moved back and forth around their longitudinal axis, while at the same time a high axial pressure is exerted on the pipes, as is the case when lowering bored piles is known per se. When bringing it down, the bottom inside the tube can be removed if this proves to be necessary or expedient. In addition, it is possible to arrange a filler bar in the interior of the locks 18, which prevents soil from penetrating into the interior of the lock and which can be pulled out again when the pipe support screed 11 has reached the desired position.

Nach dem Niederbringen von mindestens zwei nebeneinander angeordneten Rohrtragbohlen werden diese um ihre Längsachse so gedreht, daß die einander zugewandten Schlösser 18 von zwei benachbarten Tragbohlen 11 in der gewünschten Spundwandflucht liegen. Danach werden die Füllbohlen 12 entweder einzeln oder paarweise oder in Dreiergruppen mit ihren freien Rändern 30 von oben her in die Schlösser 18 der Rohrtragbohlen eingeführt und auf die für sie bestimmte Tiefe T2 in den Boden geschlagen oder gepreßt. Danach kann der Boden oder das Wasser vor der Spundwand bis auf die gewünschte Tiefe T3 entfernt werden.After bringing down at least two tubular support beams arranged side by side, they are rotated about their longitudinal axis in such a way that the locks 18 of two adjacent support beams 11 facing one another lie in the desired sheet pile wall alignment. Thereafter, the filling screeds 12 are inserted either individually or in pairs or in groups of three with their free edges 30 from above into the locks 18 of the pipe support screeds and hammered or pressed to the depth T 2 intended for them. Then the soil or water in front of the sheet pile wall can be removed to the desired depth T 3 .

Die Erfindung ist nicht auf die dargestellten und beschriebenen Ausführungsformen beschränkt, sondern es sind mehrere Änderungen und Ergänzungen möglich, ohne den Rahmen der Erfindung zu verlassen. Beispielsweise könnte die Rohrtragbohle auch aus drei oder mehr Rohrschalen zusammengesetzt werden, wobei daon die Schlitze 17 nicht einander diametral gegenüberliegen, sondern im Winkel zueinander angeordnet sind. Eine solche Ausführungsform ist dann besonders zweckmäßig, wenn angestrebt wird, daß Füllbohlen und Tragbohlen mit ihrem vorderen Rand etwa in der gleichen Ebene liegen oder wenn der Durchmesser der Rohrtragbohlen so groß Ist, daß er aus zwei Halbschalen nicht wirtschaftlich hergestellt werden kann. Ferner ist es möglich, Schlösser mit anderer Querschnittsform zu verwenden oder andere Profile zur Aussteifung des Schlitzes einzusetzen. Für Rohrtragpfähle mit kleineren Durchmessern kann unter Umständen auch vollständig auf Aussteifungsprofile verzichtet werden. Außerdem ist es möglich, die Schlösser auch auf der Innenseite der Rohrwandung mit dieser zu verschweißen oder die Rohrtragbohlen mit Füllbohlen anderen Querschnittes zu kombinieren. Um Erschütterungen weitgehend zu vermeiden, soll zweckmäßig vor dem Einbau der Füllbohlen in diesem Bereich eine Lockerungsbohrung niedergebracht werden. Der Einbau der Füllbohlen erfolgt dann mit einem Vibrator oder einem Rammhammer.The invention is not limited to the illustrated and described embodiments, but several changes and additions are possible without leaving the scope of the invention. For example, the pipe support screed could also be composed of three or more pipe shells, in which case the slots 17 are not diametrically opposite one another, but are arranged at an angle to one another. Such an embodiment is particularly expedient if the aim is that the screed and support screed lie approximately in the same plane with their front edge or if the diameter of the pipe support screed is so large that it cannot be economically produced from two half-shells. It is also possible to use locks with a different cross-sectional shape or to use other profiles to stiffen the slot. For pipe support piles with smaller diameters can under certain circumstances be completely dispensed with stiffening profiles. It is also possible to weld the locks on the inside of the pipe wall or to combine the pipe support planks with filling planks of a different cross-section. In order to largely avoid vibrations, a loosening hole should be drilled in this area before installing the filling screeds. The filling screeds are then installed using a vibrator or ram hammer.
