Abstract
Description
Die Erfindung beschreibt eine Vorrichtung zur Herstellung von Einzelschlitzen oder durchgehenden Wänden im Erdreich nach dem Mixed-in-Place-Verfahren gemäß dem Oberbegriff der Ansprüche 1 bzw. 2.The invention describes a device for Manufacture of single slots or continuous walls in the Soil according to the mixed-in-place method according to the preamble of claims 1 and Second
Die
Die Einzelrührwerkzeuge bestehen meist aus rotierenden Achsen oder Rohren, die mit verschiedenen Mischwerkzeugen besetzt sind. Dies können kurze Schneckenstücke oder durchgehende Schnecken sein, Stangen, Paddel oder Flügel und in unterschiedlichen Kombinationen und GrößenThe individual stirring tools usually consist of rotating axes or pipes using various mixing tools are busy. You can short snail pieces or be continuous snails, rods, paddles or wings and in different combinations and sizes
Durch Zugabe von flüssigen Bindemitteln wird unter Rotation der stabförmigen Einzelrührwerkzeuge der anstehende Boden gelockert und aufgemischt und es entsteht aus dem anstehenden Boden und dem Bindemittel ein Bodenmörtel.By adding liquid binders rotating the rod-shaped Einzelrührwerkzeuge the soil is loosened and mixed up and it emerges a floor mortar for the existing soil and the binding agent.
Es werden entweder einzelne Stiche hergestellt oder durch Aneinanderreihung mehrerer Stiche entstehen durchgehende Wände, die Abdichtfunktionen im Boden erfüllen, die Lasten in den Baugrund abtragen oder zur Baugrubenumschließung dienen.There are either single stitches produced or created by stringing together several stitches continuous walls, perform the sealing functions in the ground, transfer the loads into the subsoil or for construction pit enclosure serve.
Die Geräte und Verfahren nach dem Stand der Technik unterscheiden sich im Wesentlichen durch die Gestaltung der Einzelrührwerkzeuge. Im Zusammenwirken mit der Festigkeit des anstehenden Bodens und der Werkzeugform ergeben sich erhebliche Unterschiede bei der Eindringgeschwindigkeit der Vorrichtungen in den Boden und somit bei der Herstellleistung und ebenso beim Werkzeugverschleiß.The devices and processes according to the state of the art Technology essentially differ in the design of the individual stirring tools. In conjunction with the strength of the soil and the tool shape there are considerable differences in the penetration speed of the devices in the ground and thus in the manufacturing performance and also with tool wear.
Gerade bei mitteldicht bis dicht gelagerten, rolligen Böden, die für das Mixed-in-Place-Verfahren ebenfalls besonders geeignet sind, lassen sich nur sehr geringe Eindringgeschwindigkeiten erreichen.Especially with medium to dense stored, uneven floors, the for the mixed-in-place procedure as well are particularly suitable, only very low penetration speeds to reach.
Ein weiteres Problem stellt die Herstellung von dichten Anschlussfugen zwischen den einzelnen Stichen dar.Another problem is the production of tight connection joints between the individual stitches.
Die Erfindung hat die Aufgabe, ein leichtes und schnelles Eindringen der Mischvorrichtung in den Baugrund zu bewirken.The invention has the task of a easy and quick penetration of the mixing device into the ground to effect.
Gleichzeitig soll eine höhere Dichtigkeit im Bereich der Anschlussfugen zwischen einzelnen Stichen erreicht werden.At the same time, a higher tightness should be achieved reached in the area of the connection joints between individual stitches become.
Die Lösung der Aufgabe erfolgt nach
den Merkmalen der Patentansprüche
Anhand der
Die Besonderheit der Erfindung liegt
darin, dass der Boden, der unterhalb der Bohranfänger
Dadurch wird das Eindringen der Einzelrührwerkzeuge
in den Boden erleichtert. Die Auflockerung des Bodens erfolgt dadurch,
dass vor den Bohranfängern
Weiter sind die Schneidstrahlen in
der horizontalen Schnittebene des Einzelstichs so angeordnet, dass
sie im Wesentlichen mit ihrem Wirkbereich innerhalb der Stichdicke
Dies ist besonders deshalb gewünscht, damit
die Wand, die aus mehreren, aneinandergereihten Stichen besteht,
eine gleichmäßige Dicke
Der Düsenhalter
In
Die Leitung
Übliche Schneidmedien sind Suspensionen aus Wasser, hydraulischen Bindemitteln wie Zement und aus Zusatzmitteln und/oder gegebenenfalls Zusatzstoffen.usual Cutting media are suspensions of water, hydraulic binders such as cement and from additives and / or optionally additives.
Im Düsenhalter 6 am Ende der Leitung
Für die Richtung der Schneidstrahlen gibt es verschiedene Möglichkeiten.For the direction of the cutting beams there are different options.
In
Ein weiterer Vorteil dieser Schneidstrahlen
Damit während des Abteufvorgangs weder Boden
noch Bindemittelsuspension in den Ringraum zwischen rotierender
Bohrstange
Vorteil dieser Variante ist, dass
mit den Schneidstrahlen
Um das Eindringen des Düsenhalters
Diese Schneiddüse
Der vertikale Abstand des Düsenhalters
In
Die Schneiddüsen
Optimale Drücke und Pumpmengen sind dann
gegeben, wenn die Schneidstrahlen
Mit der Erfindung können unterschiedliche Verfahrensschritte
ausgeführt
werden. Die zur Bodenmörtelherstellung
erforderliche Menge an Bindemittel, kann vollständig über die Schneidstrahlen
