Description

Die Erfindung betrifft ein Verfahren zum Einbringen von schüttfähigem Zusatzmaterial in den Boden unter die Bodenoberfläche zum Verbessern der Tragfähigkeit des Bodens mittels einer Vorrichtung in Form eines Schleusenrüttlers, insbesondere ein Stopfverdichtungsverfahren mit wiederholtem Absenken und Ziehen des Schleusenrüttlers. Die Erfindung betrifft weiterhin eine Vorrichtung zum Einbringen von schüttfähigem Zusatzmaterial in den Boden unter die Bodenoberfläche zum Verbessern der Tragfähigkeit des Bodens in Form eines Schleusenrüttlers, umfassend einen Aufgabebehälter mit einer Aufgabeöffnung, ein sich unten an den Aufgabebehälter anschließendes vertikales Schleusenrohr mit einer unteren Austrittsöffnung und eine im unteren Bereich des Schleusenrohres befindliche Rüttlervorrichtung.The invention relates to a method for introducing pourable Additional material in the soil under the surface of the soil to improve the load-bearing capacity of the soil using a device in the form of a lock vibrator, in particular a Stuffing process with repeated lowering and pulling the lock shaker. The invention further relates to a Device for introducing pourable additional material into the soil under the soil surface to improve the load-bearing capacity of the bottom in the form of a lock shaker, comprising a feed container with a feed opening, one down vertical sluice tube connected to the feed container with a lower outlet opening and one in the lower area of the lock tube vibrating device.

Stopfverdichtungsverfahren der vorstehend genannten Art zur Baugrundverbesserung mit den genannten Schleusenrüttlern sind allgemein bekannt. Dabei wird ein an einem Kran aufgehängter oder an einem Mäkler geführter Schleusenrüttler in den Boden versenkt und in die entstandene Bodenöffnung Grobmaterial, z.B. Bahnschotter, Grobkies oder Split eingebracht. Durch wiederholtes Aus- und Einfahren des Schleusenrüttlers in die Öffnung entsteht eine in sich verdichtete Säule aus Grobmaterial im Boden. Das ursprünglich die Bodenöffnung einnehmende Material wird verdrängt und der umgebende Boden somit in sich ebenfalls verdichtet. Durch die Erzeugung derartiger Säulen aus Grobmaterial in rasterförmiger Anordnung entsteht ein Baugrund mit insgesamt besseren Eigenschaften zur Bebauung. Bei dem Aus- und Einfahren um jeweils beispielsweise einen Betrag von 50 cm wird jeweils ein Teil der Bodenöffnung im Boden vom Schleusenrtittler freigegeben und gleichzeitig mit schüttfähigem Grobmaterial gefüllt. Bei anschließendem erneuten Absenken des Schleusenrüttlers entsteht das zuvor genannte Verdichten des Zusatzmaterials und Verdrängen von gewachsenem Bodenmaterial. Bei Verwendung der obengenannten Grobmaterialien Bahnschotter, Grobkies oder Split als Zusatzmaterial, läßt sich das genannte Stopfverdichtungsverfahren problemlos ausführen. Die Materialien sind jedoch teuer, müssen fraktioniert und in der Regel weit herantransportiert werden. Beim Versuch Sand einzusetzen, der ggfs. vor Ort beim Ausheben von Baugruben verfügbar ist, haben sich Probleme ergeben. Erdfeuchter Sand neigt zu Brücken- bzw. Dombildung im Schleusenrüttler, das ein Nachfließen des Sandes verhindert, wobei auch die Rüttlertätigkeit diese Brückenbildung im Schleusenrohr nicht zerstören kann. Die Probleme lassen sich bisher nur dadurch lösen, daß getrockneter und damit rieselfähiger Sand verwendet wird. Hierdurch entstehen wieder erhebliche zusätzliche Kosten und Zeitverluste, die diese Vorgehensweise unwirtschaftlich erscheinen lassen.Gland compression process of the type mentioned above for Soil improvement with the lock vibrators mentioned well known. This involves hanging one on a crane or lock shaker guided by a leader in the ground sunk and coarse material, e.g. Track gravel, coarse gravel or split introduced. By repeated Extend and retract the lock vibrator into the opening a compressed column of coarse material is created in the Ground. The material that originally occupied the bottom opening is displaced and the surrounding soil also within itself condensed. By creating such columns from coarse material In a grid-like arrangement, a building plot with a total of better properties for building. When training and Retracting by an amount of 50 cm, for example each part of the floor opening in the floor by the lock fitter released and at the same time with pourable coarse material filled. When the lock vibrator is then lowered again the above-mentioned compression of the additional material occurs and displacing grown soil material. When using the above-mentioned coarse materials railway ballast, coarse gravel or split as an additional material, the above-mentioned stuffing method run easily. The materials, however, are expensive, have to be fractionated and usually transported far become. When trying to use sand, the When excavation pits are available, problems have arisen surrender. Earth-moist sand tends to form bridges or domes in the lock vibrator, which prevents the sand from flowing back, the jogging activity also forms this bridge in the Cannot destroy lock tube. The problems can be solved so far only solve that dried and thus free-flowing Sand is used. This creates significant again additional costs and wasted time doing this make appear uneconomical.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung bereitzustellen, mit denen erdfeuchter Sand bei der Durchführung von Bodenverbesserungen mittels Schleusenrüttler, insbesondere im Stopfverdichtungsverfahren zum Einsatz gebracht werden können.
