なエレクタ装置に関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an erector device for a tunnel excavating machine, and in particular to a construction method in which a reaction force is directly applied to the ground while constructing a support, and a construction method in which a reaction force is directly applied to the ground while constructing a segment. The present invention relates to an erector device suitable for use in a tunnel excavating machine that can be used in combination with a construction method in which the segment takes support force for propulsion.

As a tunnel boring machine that can handle complex geology, there are two methods: one is to take the propulsion reaction force directly from the ground while constructing a support depending on the condition of the ground, and the other is to take the propulsion reaction force from the constructed segment. There are tunnel boring machines that can be used in combination with That is,
If the ground is self-sustaining, the gripper ring is fixed by pressing the gripper shoe installed at the rear of the fuselage against the wall of the tunnel, and then the shield hull is propelled against the gripper ring by a self-propelled jack. In this case, steel shoring will be used as support. On the other hand, in soft geology where the propulsion reaction force cannot be taken by the Gritsupashyu, the shield hull is propelled by using the shield jack installed at the rear of the fuselage while constructing the segments to take up the propulsive reaction force in the segment.

る。 By the way, in a general tunnel boring machine,
It is equipped with an erector device for constructing segments, and is designed to take the propulsive reaction force by the constructed segments. Therefore, in the case of a tunnel excavating machine that takes propulsion reaction force from both the ground and the segments as described above, when using shoring, the erector device must be modified for constructing shoring, or it must be used exclusively for shoring. It is necessary to provide a construction device separate from the erector device.

Moreover, in the latter case, there are problems that increase the length of the aircraft, complicate the structure, and increase production costs.
