Abstract (en)
[origin: WO2017133986A1] The invention relates to a tunnel boring device for creating a bore from a starting point to a target point in the ground, along a predefined boring line by advancing the tunnel boring device in order to create a tunnel or for laying a pipeline in the ground using a boring tool to break up the ground; having at least one feed line for supplying a boring fluid to the boring tool; having at least one section, arranged at the rear of the boring tool, for receiving the ground which has been broken up and is present in the form of cuttings, wherein the region of the boring tool and the at least one section are essentially filled with boring fluid, and the boring fluid is provided in the region of the boring tool and within the at least one section with a pressure that essentially corresponds to the pressure in the ground at the heading face; having at least one pump for removing, from the section, the boring fluid mixed with the cuttings; having at least one conveying line for removing, from the bore, the boring fluid mixed with cuttings, this line being connected to the delivery side of the at least one pump, and wherein the at least one pump is connected to the at least one section via at least one suction line. In that context, it is provided that the pump is a jet pump which is connected to a drive line via which a driving fluid is supplied to the jet pump; that the at least one pump is arranged outside the at least one section; and that the at least one suction line contains at least one shutoff valve with which the suction line can be shut off.
