Abstract
A screwing-in system for inserting a threaded rod in the axial direction into a substrate, having a drive machine which rotationally drives a drive sleeve, it being possible to insert the threaded rod into the drive sleeve arranged on the drive machine, which drive sleeve can be connected to the threaded rod in a form-fitting manner and thus rotationally drives the threaded rod, wherein a component provided with an internal thread is fixed between the drive machine and the substrate, which component converts the rotational movement of the drive sleeve into a translational movement of the threaded rod, wherein the screwing-in machine is mounted on a carriage which is movable relative to the component.
Claims19
A method for screwing a threaded rod into soil or rock, with a drive machine comprising a drive sleeve which produces a positive engagement on the threaded rod via an internal profiling, in order to rotationally drive the threaded rod and to screw it through the internal thread of a component, wherein the rotational movement of the threaded rod being converted into a translational movement by the internal thread of the component, characterized in that the drive machine is mounted on a translationally movable carriage which is moved along the axis of the threaded rod in accordance with the feed movement of the threaded rod and characterized in that the drive sleeve interrupts the positive-locking connection with the threaded rod during a movement of the carriage counter to the screwing-in direction in order to produce a positive-locking connection again at another region of the threaded rod and in order to drive the threaded rod rotationally again.
