Description

Erdanker mit mehreren Ankerklötzen Bekannt ist die Ausführung von Erdankern, bei denen an einer Ankerkette oder einer Ankerstange befestigte Ankerkörper durch Bohrung in den Untergrundeingebracht ,werden. Der lotrechte Ankerzug wird hierbei durch die Gewichtswirkung der Ankerklötze, durch die Belastung der Ankerklötze durch den Boden und durch die an dem Umfang des durch Ankerklötze und Boden gebildeten Systems wirkende Reibung aufgenommen. Die Reibung am Umfang des zwischen den Ankerklötzen vorhandenen Bodenkörpers ist wesentlich abhängig von dem auf diese Bodenkörper ausgeübten Druck.Ground anchor with several anchor blocks The execution of Ground anchors, where anchor bodies attached to an anchor chain or rod brought into the subsoil by drilling. The vertical anchor pull will here due to the weight effect of the anchor blocks, due to the load on the anchor blocks through the ground and through those on the perimeter of the formed by anchor blocks and ground System acting friction added. The friction on the perimeter of the between the anchor blocks existing soil body is essentially dependent on the exerted on this soil body Pressure.

Bei dem bisher bekannten Verfahren der festen Verbindung der Ankerklötze mit der Ankerkette ist die Oberfläche des zwischen zwei Ankerklötzen liegenden Bodens unbelastet. Die lotrechte Bodenspannung wird dadurch in ihrem Auftreten stark begrenzt. Die Reibungskräfte .am oberen Teil der Verankerung und das Gewicht der Verankerung können nicht druckerhöhend wirken, weil sie direkt an der Wirkungsstelle auf die Ankerkette übertragen werden.In the previously known method of firmly connecting the anchor blocks with the anchor chain is the surface of the ground lying between two anchor blocks unencumbered. The vertical ground tension is thereby severely limited in its occurrence. The frictional forces at the top of the anchor and the weight of the anchor cannot have a pressure-increasing effect because they act directly on the site of action Anchor chain are transferred.

Zur Verbesserung der Ankerwirkung wird vorgeschlagen, die Ankerkette oder Ankerstange nur mit dem untersten Ankerklotz fest zu verbinden. Hierdurch wird erreicht, daß der Hauptteil der gemeinsamen lotrechten Verankerungskraft auf dem vor dem untersten Ankerkörper liegenden Bodenkörper zur Wirkung gelangt. Die Oberfläche des Bodenkörpers wird dadurch belastet, und der Querdruck des Bodens wird im unteren Bereich des Ankers wesentlich erhöht. Dadurch, daß die :oberen Ankerklötze mit der Ankerkette nicht fest verbunden sind, bietet sich weiter der Vorteil, den Boden über den Ankerklötzen ohne Behinderung durch die jeweils darüber befindlichen Ankerklötze einzubringen und besonders gut zu verdichten. Die Ankerklötze können dann auf den verdichteten Boden abgesenkt werden. Hierdurch ergibt sich eine gute Einspannung der gesamten Verankerung in den Untergrund. Das beschriebene Verfahren ergibt daher bei geringen Formänderungen eine wesentliche Erhöhung der Seitenreibung und damit seine Erhöhung der möglichen Ankerkraft selbst. Man kommt hierdurch mit wesentlich geringerer Einbettung der Anker aus, so daß gleiche Wirkung mit wesentlich geringerem Arbeitsaufwand bei größerer technischer Vollkommenheit erzielt wird. Anwendungsbeispiele zeigen die beiden Skizzen auf der anliegenden Zeichnung Blatt i. Hierin stellt Z den lotrechten oder schräg gerichteten Ankerzug dar. Er wird ausgeübt durch das Zugseil b. An diesem Zugseil ist die untere Ankerplatted fest befestigt. Die oberen Ankerplatten :oder Ankerklötze c sind nicht mit dem Zugseil fest verbunden, sondern das Zugseil ist lose durch diese hindurchgeführt.To improve the anchor effect, it is proposed to use the anchor chain or anchor rod only to be firmly connected to the lowest anchor block. This will achieves that the main part of the common perpendicular anchoring force on the comes into effect in front of the lowest anchor body. The surface The soil body is thereby stressed, and the transverse pressure of the soil is in the lower Area of the anchor significantly increased. Because the: upper anchor blocks with the If the anchor chain is not firmly connected, there is the further advantage of the ground above the anchor blocks without hindrance from the anchor blocks above to be brought in and to be compacted particularly well. The anchor blocks can then be placed on the compacted soil can be lowered. This results in good restraint the entire anchoring in the ground. The method described therefore gives with minor changes in shape, a significant increase in lateral friction and thus its increase in the possible anchor force itself. You get by with this significantly less embedding of the anchors, so that the same effect with significantly less Workload is achieved with greater technical perfection. Application examples show the two sketches on the attached drawing on sheet i. Here Z the vertical or oblique anchor pull. It is exerted by the Pull rope b. The lower anchor plate is firmly attached to this pull rope. The top Anchor plates: or anchor blocks c are not firmly connected to the pull rope, but rather the pull rope is loosely passed through it.
