In the conventional shield 1 propulsion device, the propulsion jack was fixed to the front fuselage side as described above, so the propulsion jack in Figure 7(a)
When the propulsion jack (12) is extended as shown in FIG. 2, the pressing body (18) will interfere with the inner wall of the rear body (2) on the outside of the bend. Therefore, in order to avoid this interference, the front torso (
The jack guide (15) of 1) is provided with an elastic body (19). Moreover, as shown in FIG. 7(b), on the inside of the bend, the pressing body (18) separates from the inner wall of the rear trunk (2) and cannot press the center of the segment 1-(20). In any case, the axis of the propulsion jack (12) is eccentric and inclined with respect to the segment (20).

Therefore, if the bending angle is increased beyond a certain level, the segment may be damaged. For this purpose, a structure in which the propulsion jack is fixed to the rear fuselage side has been proposed, but although the inclination between the propulsion jack and the segment is eliminated, the thrust of the propulsion jack must first be received by the rear fuselage, so the structure of the rear fuselage is is disadvantageous in terms of strength. Another problem is that the bending jack must have a large capacity in order to transmit the force from the front body to the rear body through the bending jack.

Furthermore, even if a propulsion jack is installed on the rear fuselage side so that the axes are parallel and the front fuselage is propelled by the propulsion jack, if the propulsion jack is bent while thrust is applied, the propulsion jack will Since interference occurs between the front body and the jack guide, it is not easy to bend the front body. In particular, closed type shield passers such as mud water pressurization type and closed mechanical type are hand-dug type and semi-43! Unlike open-type shield one-passing machines such as the A-mechanical type, it is necessary to always maintain the force from the face with a propulsion jack, so there was a problem in applying it to a closed-type shield passing machine.

In the present invention, the propulsion jack is slidably supported parallel to the axis of the rear shell by the jack guide provided on the inner circumference of the rear shell, but during the bending motion of the front shell, the axis of the propulsion jack is tilted. The shock absorbing material of the jacking guide absorbs and softens the force exerted on it. In addition, while the force from the face is held by most of the propulsion jacks, after releasing the other propulsion jacks, the axis of the propulsion jacks is corrected to the original using the positioning device, and then the thrust is shared with the previous propulsion jacks. By taking turns, the bending motion can be easily performed. Therefore, since the axis of the propulsion jack is always parallel to the axis of the rear fuselage, it is possible to push the segments concentrically by the pressing body connected to the tip of the piston rod of the propulsion jack, and to displace this pressing point from the reaction force point of the propulsion jack. can. Furthermore, since the base end of the cylinder of the propulsion jack is provided so as to be slidably in contact with the pressure receiving plate on the front body side, a large propulsive force is not transmitted to the rear body.
