The presses 13 support e.g. on a trailing plate or on the rotating body of the rotating union is the final tunnel lining, which e.g. is formed by a massive intermediate member, e.g. a segmental extension in front of the front end of the rotating body, or an in-situ concrete extension, e.g. an end plate or the like. With a 20 as is known per se.

Nem connected to a narrow segment housing, which is located only in the interior of the shield 10, a bearing con extends over a small partial circumference of the guide tube sole 14, which is formed by supports 15, 16, 17 and 18. The and the interior of the line leadthrough storage bracket 14 is at the same time trained as a working platform. The segment housing can be det with a housing part, which in the horizontal position at about half the height of the shield in rotatable cutting arm carriers e.g. is rotated by positive locking. The work platform can be rigidly connected to the inclusion, so that the shield can be fastened when the inner wall rotates. In the illustrated cutting arm support, the segment housing and, via the second exemplary embodiment, the support bracket 14, which is formed as a working platform of the rotating body of the rotary guide, is displaceable in the direction of advance V. The housing shield used for the cable entry is supported and guided. For this purpose, on the part of the cutting arm support is expediently also formed as a 30 inner wall of the shield on a diametrically opposite narrow segment housing, which together with the bearing member on the guide tube axially displacements 19 are provided on the guide tube, on which the guide member runs in the direction of advance V. which is the carrier 15 and 17 borrowed. In order to slidably support the cable lead-through 14 in the case of the relative axial movements between the guide carriers 18 of the support bracket which connect the ends of the two mentioned segment housings. To keep the feed of the support bracket 14 from being closed to the outside, the steps are carried out by means of hydraulic thrust piston gears 20, which are expediently connected with overlapping and roughly see the shield 10 and the support bracket 14 in an articulated, telescopically displaceable housing parts and protected in the guide parts of the supporting oversight. console lie.

In the propulsion device according to the invention, with the carriers connected to form a double I-profile, the cutting arm carrier 4015 and 16 of the bearing bracket 14, which can be rotated about the bearing member, is axially cantilevered from the axial end of the guide tube 22 by means of a mounting plate connected,

The housing part 54 is provided with a housing set 56 which extends into the segment. The cutting arm 32 is connected via a joint 35 to a ring housing 53, the shaped cutting arm carrier 36 being connected. The hinge 35 5 in the shape and dimension of the segment housing 53 is located opposite the shield axis and the axis of the guide, so that the segment housing 53 is radially offset via the housing tube 22; its hinge axis extends vertically approach 56 rotatably with the housing part 54 and that to the shield and tube axis. For pivoting the cutting arm 36 is connected, but the cutting arm 32 around the hinge 35 serve hydraulic swivel arm carrier 36 with its attachments relative to the Seglinder 37, which can be displaced in the axial direction between the cutting arm carrier 36 and the housing 53. Since the at-cutting arm 32 are articulated.

The rotary feedthrough 42 has a 35 32 around the axis of the fixed guide tube 22, the driven cutting head 33 engaging in the front end of the guide tube 22 having an annular cut rotating body 43 which carries out the end of the tube in a manner of the face. By means of different intermediate members 44 closing the end plate, pivoting of the cutting arm 32 is fastened with the aid of the pivoting cylinder and by means of a rotary bearing 45 in the guide tube 22, the working face 22 can be mounted in concentric cuts and rotatably. The supply of the above-mentioned 40 can be cut with a smooth, stepped wall. In the case of the rather occurs from a central drive station, which is arranged on the rotary movement of the cutting bearing bracket 14 carrying the cutting arm 32 or in the rear region of the shield arm support 36 about the longitudinal axis of the guide tube 22 and e.g. The rotary body 43 of the station consists of a hydraulic pump aid of the rotary drive 57, 38, 39. The connecting lines are inserted into the guide tube 22 from the La rotary feedthrough 42 via the positive connection console 14; they took 45 of the housing parts 53, 56 with them. The feed of the run through the guide tube up to the rotary cutting arm 32 in the direction of advance V takes place with the aid of the body 43, on which they are coupled in a known manner by means of a rotary thrust piston gear 26, which are connected to the bearing bracket 14, such that in the case of the rotary moving support. During this feed movement, the cutting of the rotating body 43 about the axis of the guide tube arm carrier 36 is carried along via the bearing member 23, which 22 no rotary movements are transmitted to the lines laid in the guide tube 50, which are rotatably guided on the fixed guide tube 22, which lead to a twist. Fig. 2 shows the bearing member 23 in its front-front lead these lines. thrust position, in which the thrust piston gear 26 around the The output lines 46 to 49 (Fig. 3) are extended at the other full stroke. The fact that the bearing con side of the rotating body 43 on the plate-shaped intermediate 14 in turn is shifted outwardly in the link 10 by means of the thrust piston gear 20 in the link member 44 and displaceable in the shield 10 via a line 55 through the direction of advance V in a plate leadthrough space 51 is guided, there is a particularly large feed dimension of the part in which the output lines with loop-shaped cutting machine. As mentioned, there is no additional line reserve 52 installed. The cable lead-through, as well as the possibility of carrying the support bracket 14 with the space 51 attached to it, is the interior of a segment housing 53, a fixed guide tube 22 which is axially immovable and which is connected to the intermediate member 44 and can be arranged like a shield.
