Description

Die Erfindung betrifft eine Stütze für Grabenverbauvorrichtungen, die sich zusammensetzen aus in Abständen längs und zu beiden Seiten eines Grabens senkrecht anzuordnenden Stützen, die Stützen eines Stützenpaares auf Abstand haltenden Spreizrahmen und in seitlichen Führungen der Stützen vertikal verschiebbar geführten Verbauplatten, wobei die Stütze ein von oben bis unten durchlaufendes Kastenhohlprofil aufweist und an ihrem unteren Ende mit einem keilförmigen Stützenfuß versehen ist, der eine in der Ebene der Außenwand der Stütze befindliche Schneide und eine von der Schneide schräg nach oben zur Innenseite der Stütze verlaufende, das Kastenhohlprofil unten abschließende Verschluß element aufweist.The invention relates to a support for trench lining devices that are composed from along at intervals and perpendicular to both sides of a trench supports to be arranged, keeping the supports of a pair of supports at a distance Spreading frame and guided vertically displaceably in the side guides of the supports Sheeting panels, the support being a hollow box section running from top to bottom has and at its lower end with a wedge-shaped support foot is provided, which is a cutting edge located in the plane of the outer wall of the support and one that runs obliquely upwards from the cutting edge to the inside of the support, the box hollow profile bottom closing element has.

Stützen und Grabenverbauvorrichtungen dieser Art sind bekannt aus dem europäischen Patent 0 475 382 und dem US-Patent 5 310 289 des Anmelders.Columns and trench shoring devices of this type are known from the European Applicant's patent 0 475 382 and U.S. patent 5,310,289.

Nach dem Verlegen einer Rohrleitung in den verbauten Graben wird der Graben insbesondere mit dem Aushub verfüllt und die Teile der Verbauvorrichtung zurückgeholt. Dieser Rückbau geht in der Weise vor sich, daß in mehreren Stufen Erde bis zu einer Höhe von ca. 50 cm eingefüllt, dann die Verbauplatten um etwa den gleichen Betrag hochgezogen und dann das eingefüllte Erdreich mittels Rüttelbohlen oder ähnlichen Verdichtungsvorrichtungen gegen den gewachsenen Boden verdichtet wird. Dieses Einfüllen von Erdreich, Hochziehen der Verbauplatten und Verdichten des Erdreichs wiederholt sich von Stufe zu Stufe. Dabei sind auch die Stützen hochzuziehen, damit sich in dem Raum, den die Stützen eingenommen hatten, kein Hohlraum bildet. Ein sorgfältiges Verdichten des eingefüllten Bodens ist notwendig, damit Setzungsschäden vermieden werden und die Tragfähigkeit der Einfüllung erhöht wird.After laying a pipe in the built trench, the trench becomes especially filled with the excavation and brought back the parts of the shoring device. This dismantling takes place in such a way that earth up in several stages filled to a height of approx. 50 cm, then the shoring panels by about raised the same amount and then the filled soil using vibrating planks or similar compaction devices against the grown soil becomes. This filling of soil, pulling up the shoring panels and compacting the earth repeats itself from level to level. The supports are also included to pull up so that there was no space in the space the supports had occupied Forms cavity. Careful compaction of the filled soil is necessary so that settlement damage is avoided and the load-bearing capacity of the filling is increased.

Das Hochziehen der Stützen erfordert beim Rückbau der Verbauvorrichtung die größten Anstrengungen, weil diese Stützen unter der Last des gegen die Verbauplatten drückenden Erdreichs hochgezogen werden müssen.The lifting of the supports requires the dismantling of the shoring device greatest effort because these supports under the load of against the shoring panels pressing earth must be raised.

Der Rückbau der Stützen wäre erleichtert, wenn diese Stützen erst hochgezogen werden, wenn der Graben völlig verfüllt und die Verbauplatten und die Spreizrahmen bereits rückgebaut sind. Ein derartiges Verfahren ist aber nicht zulässig, weil es nicht möglich ist, den durch das Herausziehen der Stützen im Erdreich freiwerdenden Raum ordnungsgemäß zu verfüllen und zu verdichten.The dismantling of the supports would be easier if these supports were raised when the trench is completely filled and the shoring plates and the spreading frame have already been dismantled. Such a procedure is not allowed because it is it is not possible to free the soil by pulling out the supports Filling and compacting space properly.

Der Erfindung liegt die Aufgabe zugrunde, eine Stütze für Grabenverbauvorrichtungen der eingangs genannten Art zu schaffen, mit deren Hilfe das ordnungsgemäße Verfüllen und Verdichten des Grabens und der Rückbau der Grabenverbauvorrichtung erleichtert ist.The invention has for its object a support for trench shoring devices to create of the type mentioned, with the help of which the proper Filling and compacting the trench and dismantling the trench shoring device is relieved.

Ausgehend von der eingangs beschriebenen Stütze für Grabenverbauvorrichtungen wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die Verschlußplatte leicht lösbar am Stützenfuß gehalten ist und daß zumindest im Bereich des oberen Endes der Stütze eine in das Kastenhohlprofil mündende Einfüllöffnung angeordnet ist.Starting from the support described above for trench shoring devices This object is achieved in that the closure plate easily is releasably held on the support foot and that at least in the area of the upper end the support has a filling opening opening into the hollow box section.

Nach Fertigstellung des kompletten Grabenverbaus kann die Verschlußplatte am Stützenfüß entfernt werden. Während des Rückbaus der Grabenverbauvorrichtung kann die Stütze mit Erdreich gefüllt werden, so daß beim Hochziehen der Stütze das eingefüllte Material aus dem Stützenfuß heraustritt. Dieses heraustretende Material kann zusammen mit den übrigen Stufen der Verfüllung verdichtet werden.After completion of the complete trench sheeting, the closing plate can be on Column feet are removed. During the dismantling of the trench shoring device the support can be filled with soil, so that when the support is pulled up filled material comes out of the column foot. This emerging material can be compacted together with the other stages of backfilling.

Sofern das Ziehen der Stützen auf Schwierigkeiten stößt, können zuerst die Verbauplatten und die Spreizrahmen rückgebaut werden, so daß die Stützen völlig entlastet werden. Vor dem Ziehen der Stützen werden diese mit einem dicht fallenden, vorzugsweise trockenen Material gefüllt. Das in die Stützen einzufüllende Material soll nach Kornform, Kornzusammensetzung, Ungleichförmigskeitsgrad, Oberflächenbeschaffenheit, dem Wassergehalt und den Beimengungen so beschaffen sein, daß seine Verdichtbarkeit gering ist und das frei fallende Material einen hohen Prozentsatz der Proctordichte erreicht.If it is difficult to pull the supports, the shoring panels can be used first and the spreader frames are removed so that the supports are completely relieved become. Before pulling the supports, they are covered with a tightly falling preferably filled with dry material. The material to be filled in the supports according to grain shape, grain composition, degree of non-uniformity, surface quality, the water content and the admixtures are such that its compactibility is low and the free-falling material high Percentage of Proctor density reached.

Die völlig entlastete Stütze kann ohne Schwierigkeiten gezogen werden. Dabei tritt das dicht fallende beziehungsweise das selbstverdichtende Material am Stützenfuß aus, so daß keine Hohlräume entstehen und Setzungen nicht zu befürchten sind.The fully relieved support can be pulled out without difficulty. This occurs the tightly falling or self-compacting material on the column base so that there are no voids and there is no risk of subsidence.

Damit sich innerhalb des Kastenhohlprofils beim Einfüllen des Erdreichs kein Stopfen bildet und eine sogenannte Brückenbildung in dem eingefüllten Material vermieden wird, erweitert sich der Stützenhohlraum zum unteren Ende der Stützen hin, so daß beim Anheben der Stütze auf jeden Fall das eingefüllte Material aus dem Stützenfuß heraustritt.So that there is nothing inside the box hollow profile when filling the soil Plug forms and a so-called bridging in the filled material is avoided, the column cavity extends to the lower end of the columns out, so that when the support is raised, the filled material from the Outrigger comes out.

Die aus Fig. 1 ersichtliche Grabenverbauvorrichtung setzt sich zusammen aus Stützen 1,1' die in Abständen längs des Grabens zu beiden Seiten des Grabens anzordnen sind, aus Spreizrahmen 2, welche die Stützen 1,1' eines Stützenpaares auf Abstand halten und aus Verbauplatten 3 und 4, welche in seitlichen Führungen 5 der Stützen 1,1' vertikal verschiebbar geführt sind.The trench shoring device shown in FIG. 1 is composed Support 1,1 'at intervals along the trench on both sides of the trench are to be arranged, from expansion frame 2, which supports 1, 1 'of a pair of supports Keep distance and from shoring plates 3 and 4, which in the side guides 5 of Supports 1,1 'are guided vertically.

Die in Phantomlinien gezeichneten Verbauplatten 3 und 4 sind versetzt zueinander in den Stützen 1,1' geführt, so daß sie aneinander vorbeigleiten können.The shoring plates 3 and 4 drawn in phantom lines are offset from one another in the supports 1,1 'guided so that they can slide past each other.

Wie insbesondere die Fig. 7 zeigt, weisen die Stützen 1,1' ein von oben bis unten durchlaufendes Kastenhohlprofil 10 auf. Zu beiden Seiten der Stützen 1,1' sind zwischen einem Stützflansch 25 und einem Führungsflansch 26 Führungen 5 vorgesehen, in denen die Seitenprofile der oberen und äußeren Verbauplatten 3 formschlüssig vertikal verschiebbar geführt sind. Ferner stützen sich in dieser Führung 5 auch die inneren unteren Verbauplatten 4 auf den Stützflanschen 25 ab. Dabei werden die Verbauplatten 4 von den Kantenprofilen der oberen äußeren Verbauplatten 3 umgriffen.As shown in FIG. 7 in particular, the supports 1, 1 'have a top to bottom continuous box hollow profile 10. Are on both sides of the supports 1,1 ' guides 5 between a support flange 25 and a guide flange 26 provided in which the side profiles of the upper and outer shoring plates 3 are guided positively vertically. They are also based in this Guide 5 also from the inner lower shoring plates 4 on the support flanges 25. The lining plates 4 are from the edge profiles of the upper outer Sheeting panels 3 encompassed.

An der zum Grabeninneren hinweisenden Seite der Stützen 1 ist eine vertikale Führung 6 angeordnet, in der vertikal verschiebbar eine Führungsschiene des Spreizrahmens 2 geführt ist. Der Spreizrahmen 2 stützt sich über Rollen 27 gegen die Stützflansche 25 der Stützen 1,1' ab.On the side of the supports 1 pointing towards the interior of the trench there is a vertical one Guide 6 arranged in the vertically displaceable a guide rail of the Spreading frame 2 is guided. The spreading frame 2 is supported via rollers 27 against the Support flanges 25 of the supports 1,1 '.

Wie die Fig. 2 zeigt, sind die Stützen 1,1' an ihrem unteren Ende mit einem keilförmigen Stützenfuß 8 versehen, der eine in der Ebene der Außenwand 16 der Stütze 1 befindliche Schneide 9 und eine von der Schneide 9 schräg nach oben zur Innenseite der Stütze 1 verlaufende, das Kastenhohlprofil 10 unten abschließende Verschlußplatte 11 aufweist. Diese Verschlußplatte 11 dient dazu, daß sich beim Eintreiben der Stützen 1,1' in den Boden kein aus Steinen, Erde und Lehm sich zusammensetzender Pfropfen im Kastenhohlprofil 10 festsetzt. Bei den bekannten Stützen ist diese Verschlußplatte stets angeschweißt. Bei der erfindungsgemäßen Stütze 1 ist diese Verschlußplatte 11 leicht lösbar bzw. wegnehmbar am Stützenfüß 8 befestigt.As shown in FIG. 2, the supports 1, 1 'are wedge-shaped at their lower ends Support foot 8 provided, one in the plane of the outer wall 16 of the support 1st located cutting edge 9 and one of the cutting edge 9 obliquely upwards to the inside the support 1 extending, the box hollow section 10 below closing plate 11 has. This closure plate 11 is used so that when driving in Do not support 1,1 'in the ground made up of stones, earth and clay Graft in the box hollow section 10. In the known supports, this closure plate always welded on. In the support 1 according to the invention, this is Locking plate 11 is easily detachably or removably attached to the column foot 8.

Wie die Fig. 2, 3 und 5 zeigen, ist bei der erfindungsgemäßen Stütze 1 die Verschlußplatte 11 über Führungsschienen 14, die an den Außenseiten der Seitenwände des Kastenhohlprofils 10 angebracht sind, und Halteschienen 15, welche die Führungsschienen übergreifen zum Grabeninneren hin verschiebbar gehalten und geführt. Damit beim Eintreiben der Stütze 1 in das Erdreich die Verschlußplatte 11 sich nicht verschiebt, dient ein Riegel 13, der die Verschlußplatte 11 in der Schließstellung hält. Erst nach Fertigstellen des Grabenverbaus wird die Verschlußplatte 11 durch Öffnen des Riegels 13 zum Grabeninneren hin weggezogen. Dazu dient beispielsweise ein Haken 24, der in eine an der Verschlußplatte 11 befestigten Öse 12 eingreift. Der Riegel 13 kann von einer Feder in Schließstellung gehalten und gegen die Wirkung dieser Feder geöffnet werden.2, 3 and 5 show, the closure plate is in the support 1 according to the invention 11 via guide rails 14 on the outer sides of the side walls of the hollow box section 10 are attached, and holding rails 15, which the guide rails spill over to the interior of the trench and held guided. Thus, when driving the support 1 into the ground, the closure plate 11 does not move, a bolt 13 is used, the locking plate 11 in the closed position holds. Only after the trench sheeting has been completed is the closure plate 11 pulled away by opening the latch 13 to the interior of the trench. It serves for example a hook 24, which in an eyelet attached to the closure plate 11 12 engages. The bolt 13 can be held in the closed position by a spring and be opened against the action of this spring.

Wie die Fig. 6 zeigt, sind an der Außenwand 16 der Stütze 1 in Abständen übereinander Ausnehmungen 17 angeordnet zum Einhaken eines Zugmittels, mit dem die Stütze 1 beim Rückbau hochgezogen wird. In diese Ausnehmungen 17 ist ein Einfülltrichter 18 ansetzbar, der eine in die Ausnehmungen 17 einsetzbare Tülle 19 aufweist. Mit Hilfe von aus Fig. 7 ersichtlichen Klammern 20, die verschwenkbar am Einfülltrichter 18 angelenkt sind, kann der Trichter 18 an der Stütze 1 befestigt werden, indem die Klammern 20 so eingeschwenkt werden, daß sie die Führungsflansche 24 der Stütze 1 hintergreifen. Bei dieser Ausführungsform der Erfindung ist die Schlagplatte 7 auf das obere Ende der Stütze 1 aufgeschweißt. Beim Rückbau der Stütze 1 kann der Einfülltrichter 18 auch an tiefer angeordneten Ausnehmungen 17 der Stütze 1 eingesetzt werden.6 shows, are on the outer wall 16 of the support 1 at intervals one above the other Recesses 17 arranged for hooking a traction device with which the Support 1 is pulled up during dismantling. In these recesses 17 is a Filling funnel 18 can be used, which has a spout 19 which can be inserted into the recesses 17 having. With the help of Fig. 7 visible brackets 20 which are pivotable are hinged to the hopper 18, the funnel 18 can be attached to the support 1 are by pivoting the brackets 20 so that they the guide flanges 24 reach behind the support 1. In this embodiment of the invention the striking plate 7 welded onto the upper end of the support 1. When dismantling the The filling funnel 18 can also support 1 at recesses 17 arranged lower the support 1 can be used.

Bei der aus den Fig. 8 und 9 ersichtlichen Ausführungsform der Erfindung ist die Schlagplatte 7' der Stütze 1' wegnehmbar bzw. aufklappbar angeordnet. In diesem Fall kann der Einfülltrichter 18' auf das geöffnete obere Ende der Stütze 1' aufgesetzt werden. Damit der Einfülltrichter zuverlässig gehalten wird, hat er eine Tülle, die im wesentlichen dem Innenquerschnitt des Kastenhohlprofils 10 der Stütze 1' entspricht. Ferner ist noch ein Aufsetzrand 23 vorgesehen, mit welchem der Einfülltrichter 18' auf das obere Stützenende aufgesetzt wird.In the embodiment of the invention shown in FIGS. 8 and 9, the Striking plate 7 'of the support 1' can be removed or opened. In this In this case, the hopper 18 'can be placed on the open upper end of the support 1' become. So that the hopper is held reliably, it has a spout, which essentially corresponds to the inner cross section of the hollow box section 10 of the support 1 ' corresponds. Furthermore, an attachment edge 23 is also provided, with which the filling funnel 18 'is placed on the upper end of the support.

Wie die Fig. 10 zeigt, wird der Querschnitt des Kastenhohlprofils 10 zum unteren Ende der Stütze hin größer. Auf diese Weise wird eine Brückenbildung des eingefüllten Materials vermieden und dafür gesorgt, daß das eingefüllte Material aus dem Stützenfuß heraustritt, wenn die Stütze angehoben wird. Weil die Außenwand 30 der Stütze sowie die Seitenwände des Kastenhohlprofils 10 vertikal verlaufen, ist die Innenwand 31 im unteren Bereich so geneigt, daß der Querschnitt nach unten größer wird. Der untere Bereich mit der geneigten Innenwand 31 erstreckt sich über 2 bis 3,5 m, weil der Spreizrahmen 2 oberhalb dieses Bereiches in der Stütze geführt ist und der Raum der Spreizrahmenführung 6 für die nach-außen-Neigung der Innenwand 31 zur Verfügung steht. As shown in FIG. 10, the cross section of the hollow box section 10 becomes the lower one End of the support larger. In this way, bridging of the filled Material avoided and ensured that the filled material from the The column foot comes out when the column is raised. Because the outer wall 30 of the The support and the side walls of the hollow box section 10 are vertical Inner wall 31 inclined in the lower region so that the cross section is larger downwards becomes. The lower region with the inclined inner wall 31 extends over 2 to 3.5 m, because the spreading frame 2 is guided above this area in the support and the space of the expansion frame guide 6 for the outward inclination of the inner wall 31 is available.
