Description

Die Erfindung betrifft ein Verfahren zur Sanierung von Stützmauern mittels Erdankern, die durch die Stützmauer in den dahinter anstehenden gewachsenen Boden und ggf. als Felsanker bis in dahinter liegenden Fels getrieben und verankert werden.The invention relates to a method for the remediation of Retaining walls by means of ground anchors, which go through the retaining wall in the growing soil behind it and possibly as Rock anchor driven into the rock behind and be anchored.

Die Sicherung von neu errichteten oder älteren Stützmauern durch Erdanker bzw. Felsanker ist bekannt. Die Anwendung dieses Verfahrens setzt voraus, daß die auftretenden Ankerkräfte in die Stützmauer eingeleitet und dort aufgenommen werden können.Securing newly erected or older retaining walls through ground anchors or rock anchors is known. The application this procedure presupposes that the occurring Anchor forces are introduced into the retaining wall and absorbed there can be.

Wenn eine zu sanierende Stützmauer noch einen ausreichenden Verbund aufweist und beispielsweise nur hinsichtlich ihrer Standsicherheit gefährdet ist, reicht es in den meisten Fällen aus, die Ankerkräfte über Lastverteilungsplatten an der Vorderseite der Stützmauer einzuleiten. Wenn die Stützmauer jedoch keinen ausreichenden Verbund mehr aufweist, reicht eine örtlich begrenzte Krafteinleitung aus den Ankern in die Stützmauer nicht aus. Deshalb ist ein bekanntes Verfahren entwickelt worden (EP 0 290 941 B1), bei dem hinter der Stützmauer im Bereich der einzubringenden Erdanker Hohlräume ausgespült und mit Zementmaterial gefüllt werden, das einen die Ankerkraft aufnehmenden Lastverteilungskopf an der Rückseite der Stützmauer bildet. Auf diese Weise wird die Stützmauer vom Erddruck entlastet. Der hierfür erforderliche Arbeitsaufwand ist jedoch verhältnismäßig hoch. Das bekannte Verfahren ist außerdem nicht ausreichend, wenn der Verbund der zu sanierenden Stützmauer zumindest in einzelnen Bereichen kaum noch gegeben ist und/oder wesentliche Sanierungsmaßnahmen auch an der Mauervorderseite erforderlich sind, beispielsweise bei Betonstützmauern, bei denen die Sichtseite durch fehlende Bindemittel absandet, abfällt und freiliegt.If a retaining wall to be renovated is still sufficient Has composite and, for example, only with regard to their Stability is at risk, in most it is enough Cases, the anchor forces on load distribution plates the front of the retaining wall. If the Retaining wall, however, no longer has a sufficient bond, a local force transmission from the anchors is sufficient not out into the retaining wall. That is why it is known Process has been developed (EP 0 290 941 B1), in which behind the retaining wall in the area of the ground anchors to be inserted Cavities are flushed out and filled with cement material, one on the load distribution head receiving the anchor force the back of the retaining wall. In this way the Retaining wall relieved of earth pressure. The one required for this However, workload is relatively high. The known Procedure is also not sufficient if the composite the retaining wall to be renovated, at least in some cases Areas are hardly given and / or essential Refurbishment measures also required on the front of the wall are, for example in concrete retaining walls, where the Visible side sanded, falling and missing binder exposed.

Aufgabe der Erfindung ist es daher, ein Verfahren der eingangs genannten Gattung so auszubilden, daß mit verhältnismäßig geringem Arbeitsaufwand eine vollständige Sanierung auch von stark geschädigten Stützmauern ermöglicht wird.The object of the invention is therefore a method of train the type mentioned in such a way that with relative Complete renovation with little effort also made possible by heavily damaged retaining walls.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß im Abstand vor der Stützmauer jeweils eine Fertigteilplatte auf Gründungspfeiler gesetzt wird, daß der Spalt zwischen der Stützmauer und der Fertigteilplatte mit Beton vergossen wird und daß die Erdanker durch Ankerlöcher der Fertigteilplatte und durch die Stützmauer hindurch eingebracht und gegen die Fertigteilplatte verspannt werden.This object is achieved in that in A precast slab in front of the retaining wall Foundation pillar is set that the gap between the Retaining wall and the precast slab is poured with concrete and that the ground anchors through anchor holes in the precast slab and inserted through the retaining wall and against the Precast panel to be clamped.

Die vor die zu sanierende Stützmauer gesetzten Fertigteilplatten und der Ausgleichsbeton nehmen die Ankerkräfte aus den Erdankern auf und leiten diese Kräfte gleichmäßig verteilt in die Stützmauer und den dahinterstehenden Beton ein. Die Betonfüllung gleicht Unebenheiten, äußere Schadstellen und bereits eingetretene Verformungen bzw. Verlagerungen der Stützmauer aus, so daß keinerlei Sanierungsmaßnahmen an den Stützmauern selbst erforderlich sind.The prefabricated panels placed in front of the retaining wall to be renovated and the leveling concrete take away the anchor forces the ground anchors and conduct these forces evenly distributed in the retaining wall and the concrete behind it on. The concrete filling resembles unevenness, external damage and deformations or displacements that have already occurred the retaining wall, so that no renovation measures the retaining walls themselves are required.

Da die Gründungspfeiler im wesentlichen nur das Gewicht der vorgesetzten Fertigteilplatten sowie des Ausgleichsbetons aufnehmen, reichen wenige, statisch schmal dimensionierte Gründungspfeiler aus, die in einfacher Weise in Bohrlöcher eingesetzt oder in diesen errichtet werden können.Since the foundation pillars essentially only the weight of the prefabricated precast slabs and the leveling concrete few, statically narrow dimensions are sufficient Foundation pillars made in simple ways in boreholes can be used or built in this.

Der auf die zu sanierende Stützmauer wirkende Erddruck wird durch die Erdanker in den gewachsenen Boden übertragen, so daß kein erhöhter Fundierungsaufwand zur Übertragung von Vertikalkräften an den Gründungspfeilern erforderlich ist.The earth pressure acting on the retaining wall to be renovated transmitted through the ground anchors into the grown soil, so that no increased foundation effort for the transfer of Vertical forces on the foundation pillars are required.

Vorzugsweise sind benachbarte Fertigteilplatten schubfest miteinander verbunden, um Schnittkräfte zwischen benachbarten Wandabschnitten zu übertragen.Adjacent prefabricated panels are preferably shear-resistant interconnected to create cutting forces between adjacent ones Transfer wall sections.

Die Herstellung der Gründungspfeiler, die wie axial beanspruchte Pfähle zur Lastabtragung dimensioniert werden, ist verhältnismäßig einfach, da das aufzunehmende Gewicht gering ist und die in frostfreier Tiefe meist schon beträchtliche Bodenfestigkeit nur geringe Abmessungen der Gründungspfeiler erfordert. Beispielsweise können die Gründungspfeiler als Fertigteile aus Beton oder Stahl dynamisch eingetrieben werden. Gründungspfeiler aus Ortbeton können leicht in Bohrlöcher eingesetzt werden, die wegen der Kapillarkohäsion vorübergehend standfähig sind. Auch Kombinationsbauweisen kommen dafür in Frage, zum Beispiel mit einem schrittweise durch Verdrängen aufgeweiteten und wiederholt mit Trockenmörtel verfüllten Bohrloch unter Verwendung eines pneumatischen Hammers.The manufacture of the foundation pillars that like axial stressed piles are dimensioned for load transfer, is relatively easy because of the weight to be absorbed is low and mostly in the frost-free depth considerable soil strength only small dimensions of the Foundation pillar required. For example, the Foundation pillars as prefabricated parts made of concrete or steel be driven dynamically. Foundation pillar made of in-situ concrete can easily be inserted in boreholes, which because of the Capillary cohesion is temporarily stable. Also Combination designs are possible, for example with a gradually widened by displacement and repeatedly filled with dry mortar under Use of a pneumatic hammer.

Nach dem Aufstellen werden die Fertigteilplatten vorübergehend abgestützt, bis der Beton in die ggf. bewehrte Fuge zwischen der Fertigteilplatte und der Stützmauer eingefüllt und ausreichend ausgehärtet ist. Dies kann durch eine herkömmliche Abstützung an der Plattenaußenseite geschehen. Stattdessen ist es in weiterer Ausgestaltung des Erfindungsgedankens auch möglich, die Fertigteilplatten mittels Anschlußteilen, vorzugsweise Dübeln, mit der Stützmauer provisorisch zu verbinden, bevor die Fuge mit Beton vergossen wird. Damit werden zusätzliche Abstützmaßnahmen überflüssig.After installation, the precast panels become temporary supported until the concrete in the possibly reinforced joint filled between the precast slab and the retaining wall and is sufficiently hardened. This can be done through a conventional support on the outside of the plate. Instead, it is a further embodiment of the inventive concept also possible using the precast panels Connection parts, preferably dowels, with the retaining wall to connect provisionally before grouting the joint with concrete becomes. This eliminates the need for additional support measures.

Die Fertigteilplatte und/oder der Ausgleichsbeton kann mit einer Bewehrung versehen werden. Insbesondere ist es vorteilhaft, die Fertigteilplatte bei ihrer Herstellung mit gelochten Ankerköpfen zu versehen, durch die die Erdanker eingebracht werden. Diese Ankerköpfe dienen der Einleitung der Ankerkräfte in die üblicherweise verhältnismäßig dünnen Fertigteilplatten.The precast slab and / or the leveling concrete can also be used a reinforcement. In particular it is advantageous to use the precast plate in their manufacture to provide perforated anchor heads through which the ground anchors be introduced. These anchor heads are used for introduction the anchor forces in the usually relatively thin Precast panels.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung näher erläutert, das in der Zeichnung dargestellt ist.An exemplary embodiment of the invention is described in more detail below explained, which is shown in the drawing.

Die Zeichnung zeigt in einem senkrechten Schnitt eine zu sanierende Stützmauer 1, beim dargestellten Ausführungsbeispiel eine Betonmauer mit einem Winkelfundament 2.The drawing shows one in a vertical section renovating retaining wall 1, in the illustrated embodiment a concrete wall with an angular foundation 2.

In geringem Abstand vor der Stützmauer 1 werden Gründungspfeiler 5 in Bohrlöcher 3 im Boden 4 eingesetzt, die bis in frostfreie Tiefen reichen. Beispielsweise handelt es sich um vorgefertigte Gründungspfeiler aus Beton oder Stahl. Soweit erforderlich, werden die Gründungspfeiler 5 mit Pfeilerköpfen 5a aus Beton, Stahl oder mit einer Anschlußbewehrung, versehen.At a short distance from the retaining wall 1 are foundation pillars 5 inserted in boreholes 3 in the bottom 4, which up to frost-free depths are enough. For example, it is prefabricated foundation pillars made of concrete or steel. So far required, the foundation pillars 5 with pillar heads 5a made of concrete, steel or with a connecting reinforcement, Mistake.

Vor der Montage der Fertigteilplatten 6 wird eine statische Bewehrung für die Ausgleichsbetonschicht an die Stützwand mittels Dübeln oder dgl. montiert. Danach werden auf die Gründungspfeiler 5 jeweils im Abstand vor der Vorderseite der Stützmauer 1 Fertigteilplatten 6 gesetzt. Hierbei handelt es sich beispielsweise um Beton-Halbfertigplatten, die mit einer Bewehrung 7 versehen sind. Die Fertigteilplatten 6 weisen gelochte Ankerköpfe 8 auf.Before the assembly of the prefabricated panels 6, a static Reinforcement for the leveling concrete layer on the retaining wall mounted using dowels or the like. Then be on the Foundation pillars 5 each in front of the front Retaining wall 1 precast panels 6 set. This is what it is about are, for example, semi-finished concrete slabs with a Reinforcement 7 are provided. The precast panels 6 have perforated anchor heads 8.

Zur vorübergehenden Standsicherung der Fertigteilplatten 6 können diese mittels Anschlußteilen, beispielsweise Dübeln 9, mit der Stützmauer 1 verbunden werden. Stattdessen oder zusätzlich ist es auch möglich, die Fertigteilplatten 6 an ihrer Vorderseite abzustützen. Sodann wird der zwischen der Stützmauer 1 und den Fertigteilplatten 6 bestehende, ggf. bewehrte Spalt 10 mit einer aus Beton bestehenden Füllung vergossen.For temporary stability of the precast panels 6 can this by means of connecting parts, for example dowels 9, be connected to the retaining wall 1. Instead, or in addition, it is also possible to attach the precast panels 6 support their front. Then the one between the Retaining wall 1 and the prefabricated panels 6 existing, possibly reinforced gap 10 with a concrete filling shed.

Anschließend werden durch die Löcher der Ankerköpfe 8 der Fertigteilplatte 6 und durch die Stützmauer 1 Erdanker 12 in den hinter der Stützmauer 1 anstehenden gewachsenen Boden 13 eingebaut und in herkömmlicher Weise verankert. Hierzu können beispielsweise mittels eines Verdrängungshammers oder einer Bohrschnecke Bohrlöcher in den gewachsenen Boden 3 gebohrt werden. Anschließend werden Zugstäbe 14 in die Bohrlöcher eingesetzt und der Ringspalt wird zur Schubübertragung mittels Mörtel oder verdichtetem Granulat (Prinzip des Sandankers) gefüllt. Die Zugstäbe 14 der Erdanker 12 ragen durch die Ankerköpfe 8 der Fertigteilplatten 6 und werden gegen die Schubübertragungsstrecke im gewachsenen Boden mittels aufgeschraubter Ankermuttern 15 oder in ähnlicher Weise leicht angespannt.Then 8 through the holes of the anchor heads Precast 6 and through the retaining wall 1 ground anchor 12 in the growing soil 13 behind the retaining wall 1 installed and anchored in a conventional manner. You can do this for example by means of a displacement hammer or a Auger holes drilled in the grown soil 3 become. Then tie rods 14 are inserted into the boreholes used and the annular gap is used for thrust transmission using mortar or compacted granulate (principle of Sand anchor) filled. The tension rods 14 of the ground anchor 12 protrude through the anchor heads 8 of the precast panels 6 and against the thrust transmission line in the grown soil by means of screwed-on anchor nuts 15 or similar Way slightly tense.

Die auftretende Vertikalkraft wird in die Gründungspfeiler 5 abgetragen, während die Horizontalkraft in die Erdanker 12 abgetragen wird. Dadurch ergibt sich ein geringer Material- und Arbeitsaufwand für die Sanierung der Stützmauer 1. Die Sanierung kann verhältnismäßig schnell durchgeführt werden und erfordert nur geringe Eingriffe in der Umgebung der zu sanierenden Stützmauer 1. Dadurch wird auch den Anforderungen des Umweltschutzes und Bodenschutzes besser Rechnung getragen als bei herkömmlichen Verfahren.The vertical force that occurs is shown in the foundation pillars 5 removed while the horizontal force in the ground anchor 12 is removed. This results in a low material and Workload for the renovation of the retaining wall 1. The Refurbishment can be carried out relatively quickly and requires little intervention in the area surrounding the renovating retaining wall 1. This also meets the requirements environmental protection and soil protection better taken into account than with conventional methods.
