Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verfestigen von Bodenabschnitten, insbesondere für Hebungsinjektionen, wobei ausgehend von beabstandeten Bohrungen in Verbindung mit dem Einbringen von Injektionsmedien eine Hebungsinjektion, Bodenverfestigung, Kluftinjektion oder Rohrschirminjektion erfolgt, dabei zunächst Bohrungen in den Boden eingebracht und anschließend über ein mehrfach verpressbares Injektionsrohr ein Injektionsmedium eingepresst wird.
Während es Aufgabe der Erfindung ist, ein Verfahren sowie eine Vorrichtung der eingangs genannten Art im Sinne einer Verfahrensoptimierung, insbesondere beim Bohren gegen drückendes Wasser, derartig weiterzubilden, dass bei Reduzierung der Anzahl von Arbeitsgängen, kleinem Bohrdurchmesser und leistungsschwächerem Bohrgerät, ohne aufwändigem Ausbau des Außenbohrgestänges vor der Injektion eine einen Bodenentzug und damit Setzungen vermeidende Arbeitweise ermöglicht wird, die Einbaubarkeit des Injektionsrohres (Manschettenrohres) uneingeschränkt abgesichert und durch die Gewährleistung der Lagesicherung für das Injektionsrohr eine gezielte Einbringung des Injektionsmediums im Boden vorgenommen sowie das Bohren auch unter engen räumlichen Verhältnissen (im Bereich von Tunnelvortriebsmaschinen; in Röhren und Kellern o. ä.) gewährleistet werden kann, wird diese bei einem gattungsgemäßen Verfahren dadurch gelöst, dass ein stählernes, selbst als mehrfach verpressbares Injektionsrohr (Manschettenrohr) (4) ausgestaltetes und bodenseitig mit einer Bohrkrone (3) ausgestattetes Außenbohrgestänge (1) direkt in den Boden (15) eingebohrt wird, eine Mantelmischung (16) direkt beim Bohren oder nach dem Erreichen der Endeinbohrtiefe über das Innengestänge (2) und die Bohrkrone (3) eingebracht, das Innengestänge (2) gezogen und anschließend das Verpressen des Injektionsmediums (18) in den einzelnen Stufen (elastische Manschetten in Längserstreckung des Injektionsrohres) mittels eines, in das Injektionsrohr (4) eingebauten Packers (19) vorgenommen wird, wobei das Injektionsrohr (4) im Boden (15) als verlorenes Bohr- und Injektionsrohr (4) mit Bohrkrone (3) verbleibt oder nach der Injektion zurückgebaut wird.
