It is not necessary to change its posture until it is delivered, and since it can be delivered to the erector 15 in a state corresponding to the inner peripheral surface 20b of the new tunnel 20 being constructed, the segment 22 can be transferred from the vertical shaft 6 to the excavation site 8 It can be efficiently and safely transported to the elector 15 provided in the. Further, during the segment assembly work, the plurality of segments 22 loaded on the carrier truck 32 are sequentially transferred onto the temporary placing member 60 by using the retracted slide devices 55, 55 (of course, the carrier truck 32 is temporarily placed. By emptying the carrier truck 32 by appropriately retracting it from the member 60), as shown in FIG.
2 becomes unnecessary and the carriage 32 can be returned to the shaft 6, so that the carriage 32 can be operated efficiently and the segment 22 can be carried efficiently.

In the above embodiment, the delivery device 50 delivers the segment 22 to the erector 15 by driving the pair of slide devices 55 to move along the guides 51 and 52. It may be moved and driven in any manner as long as the segment 22 can be delivered to the fifteen. For example, instead of the slide device 55 that is moved and driven along the pair of guides 51 and 52, a belt that can convey and drive the pair of segments 22 is free. Conveyor carrier 32
From the trolley 32 to the erector 15, the segment 22
You may hand it over. In addition, in the above-described embodiment, the slide device 55 of the delivery device 50 is provided so as to be capable of projecting and retracting, so that the loading portion 33 of the transport cart 32 is provided.
Although the mounting portion 58 of the slide device 55 of the delivery device 50 can be moved and driven relatively in the up and down direction, what if the loading portion 33 and the mounting portion 58 can be moved in the up and down direction relative to each other? For example, the loading section 33 of the carriage 32 may be provided so as to be capable of projecting and retracting, or both the loading section 33 and the loading section 58 may be provided so as to be capable of projecting and retracting. Needless to say. Furthermore,
In the above-described embodiment, the length of the mounting portion 58 of the slide device 55 of the feeding device 50 is formed to be slightly smaller than the segment width L2 of the segment 22, so that the segments 22 loaded on the carrier truck 32 can be transferred one by one. The transport cart 32 is transported, but if the segment 22 can be delivered from the transport cart 32 to the erector 15 one by one, the transport cart 32
It goes without saying that any number of the segments 22 stacked on each other may be transported and the length of the mounting portion 58 may be set in any manner. Of course, if the length of the mounting portion 58 is set to be long so that the segments 22 that can be loaded on the carrier truck 32 can be mounted at one time, the plurality of segments 22 carried by the carrier truck 32 can be temporarily placed at once. 6
It is needless to say that the carrier truck 32 can be used efficiently because it can be installed on the 0.

As described above, the present invention has the excavation site such as the excavation site 8 where the segments such as the segment 22 are assembled by the erector such as the erector 15, and the vertical shaft 6 or the like into which the segment can be brought in from the outside. The vertical shaft of
In a tunnel such as a new tunnel 20 which is being constructed and is composed of a plurality of segments provided with temporary pipes such as temporary pipes 5 extended from the excavation site to the vertical shaft, a transport rail is provided above the temporary pipes 5a. A segment such as a carrier truck 32 in which a track such as 31 is provided along the temporary pipe, and a segment loading section such as a loading section 33 that supports the inner peripheral surface 22a of the segment is formed on the track. A segment delivery device such as a delivery device 50 having a segment receiving means such as a slide device 55 for supporting an inner peripheral surface of the segment is provided adjacent to an erector provided at the excavation site, in which a transporting vehicle is provided so as to travel freely. , The segment receiving means is provided so as to be movable along the track between the erector and the segment carrier, Since it is configured provided as the car of the segment loading portion and a segment receiving means of the segments delivery device may move relative vertically driven,

Since the loading section of the segment carrier supports the inner peripheral surface of the segment on the track provided at the upper portion of the temporary pipe, the segment carried in from the vertical shaft is constructed as the inner peripheral surface of the segment. It can be loaded on the segment carrier by corresponding to the inner peripheral surface of the inside tunnel. Also,
Since the loading section of the segment carrier and the segment receiving means of the segment sending device are configured to support the inner peripheral surface of the segment in the same manner, only the loading section and the segment receiving means are moved in the vertical direction relatively. so,
It is possible to transfer a segment loaded corresponding to the inner peripheral surface of a tunnel being constructed on a segment carrier to the segment receiving means from the segment carrier while keeping the state corresponding to the inner peripheral surface of the tunnel being constructed. it can. Further, since the segment receiving means is driven to move between the erector and the segment carrier, the segment can be transferred from the segment receiving means to the erector without limiting the movable range of the erector. . Therefore, when performing renewal work on aged pipes such as sewer pipes that have been damaged or aged, making use of the functions of the aged pipes, in the tunnel under construction with temporary pipes, carry in from the vertical shaft for material loading. The segment does not need to change its posture until it is delivered to the erector, and it can be delivered to the erector in a state where it corresponds to the inner surface of the tunnel under construction, so the segment can be transferred from the vertical shaft to the excavation site. It can be efficiently and safely transported to the erector provided in the.
