Apparatus and method for the conveyance of the degradation bottom in a shield tunneling machine (svm)

摘要

Device for the conveyance of the degradation bottom in a svm which are derived from a lower region of a degradation space between the cutting rotor and of a thrust wall by means of this to a rear point, behind the bulkhead a pipe feed system is arranged for conveying of the soil material from the degradation of space in a region behind it, the pipe feed system at least one of a tubular guide cylinder tube, which is guided by a linear drive parallel to the axis of the svm is movable, the thrust wall at least one opening, to which the end of the cylinder pipe is aligned and the of a slide can be selectively opened or closed, further comprising the linear drive is designed in such a way that it the cylinder tube advances in a forward position with the front end of the cylinder pipe in or on the opening or through the opening and pushes it back into a rear position, in which the front end of the cylinder pipe from the wall opening is clear, wherein the cylinder tube can be released by the linear drive, the guide with a lateral opening in the region of the cylinder tube into the rear position, a transfer device is provided, with which the dissolved cylinder tube can be grasped and from the rear or back position to a laterally and vice versa is made available by the carriage is movable and the carriage is driven by a linear conveyor device, which extends through the svm extends rearwardly.
