Abstract

Die Erfindung betrifft ein Aufweitwerkzeug (24) und eine Vorrichtung (10) zum Aufweiten einer im Erdreich vorhanden Durchgangsöffnung. Das Aufweitwerkzeug (24) hat einen Verbindungsbereich (30), über den eine Zug- und/oder Schubkraft in das Aufweitwerkzeug (24) einleitbar ist. Ferner hat es einen Aufweitbereich (31), der zumindest in einem Teilbereich einen größeren Querschnitt als die im Erdreich (18) vorhandene Durchgangsöffnung hat. Ferner hat es einen Zentrierbereich (40), der in Bewegungsrichtung P1 des Aufweitwerkzeugs (24) zum Aufweiten der Durchgangsöffnung gesehen stromabwärts des Aufweitbereichs (31) angeordnet ist. Der Aufweitbereich (31) hat mindestens eine Öffnung (33, 35, 37), durch die Erdreich (18) und/oder Spülflüssigkeit in eine durchgehende Öffnung des Zentrierbereichs (40) eintreten kann, wobei das Erdreich und/oder die Spülflüssigkeit durch die durchgehende Öffnung des Zentrierbereichs (40) durchgeleitet wird.

The invention relates to a widening tool (24) and a device (10) for expanding a passage opening provided in the ground. The expansion tool (24) has a connection region (30), via which a pulling and / or pushing force can be introduced into the expansion tool (24). Furthermore, it has a widening region (31), which has a larger cross-section than the passage opening present in the ground (18), at least in one subarea. Further, it has a centering area (40), which is arranged in the direction of movement P1 of the expansion tool (24) for widening the passage opening downstream of the expansion area (31). The expansion region (31) has at least one opening (33, 35, 37) through which soil (18) and / or rinsing liquid can enter into a through opening of the centering region (40), wherein the soil and / or the rinsing liquid pass through the through-flow Opening the centering area (40) is passed.
