[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a segment assembling method and a segment assembling apparatus, and more particularly to a method for integrally connecting a pair of upper and lower wing segments and a support.
The present invention relates to a technique for simultaneously attaching a pair of wing segments together with a support to upper and lower wing-shaped walls.

[0002]

2. Description of the Related Art In a tunnel excavated by a multiple shield excavator, wing-shaped wall surfaces are formed on upper and lower wall portions of a boundary between right and left circular tunnel portions, and these wing-shaped wall surfaces have arcs. Instead of plate-like segments,
The wing segments formed for the wing-shaped wall are assembled. By the way, in order to increase the strength of the mounting structure of the wing segment that is mounted on the wing-shaped wall,
Usually, a support is inserted between a pair of upper and lower wing segments to reinforce it.

Conventionally, in a technique of assembling a pair of upper and lower wing segments and a support on upper and lower wing-shaped wall surfaces, a single erector mounts the wing segment on a lower (or upper) wing-shaped wall surface, and then, Then, after assembling the wing segments to the upper (or lower) wing-shaped wall, the interval between the pair of wing segments is forcibly expanded by more than 10 mm using a plurality of hydraulic jacks or the like. The strut is supplied vertically between the pair of wing segments, and the interval between the upper and lower wing segments is reduced so that the strut is sandwiched, and the strut and the pair of wing segments are connected to each other. .

[0004] The applicant of the present invention supplies the wing segment to one common erector which can sequentially assemble a pair of upper and lower wing segments on the upper and lower wing-shaped walls in the above-described conventional technique. An application has been made and has been made for a column supply device for vertically supplying a column between a pair of upper and lower wing segments mounted on a wing-shaped wall surface (see Japanese Patent Publication No. 8-19837).

[0005]

According to the prior art, when a pair of upper and lower wing segments and a support are mounted on upper and lower wing-shaped wall surfaces, a pair of wing segments are mounted on the upper and lower wing-shaped wall surfaces with one erector. Must be assembled one by one, so it is difficult to increase the work efficiency of assembling the wing segments and shorten the cycle time. Further, after a pair of wing segments are assembled on the upper and lower wing-shaped walls, the interval between the pair of upper and lower wing segments must be forcibly expanded in order to supply the support upright. The workload for assembling the segments increases, and the work efficiency also decreases.

Moreover, in order to forcibly increase the interval between the pair of upper and lower wing segments and to incorporate the support there,
Inability to accurately connect the pair of wing segments and the support columns, and the inability to apply a highly rigid wing segment, requiring reinforcement of the wing segments even in the secondary lining work after assembling the segments. Since a plurality of hydraulic jacks and the like for forcibly increasing the interval between the pair of wing segments are separately required, there is a problem that the manufacturing cost of the segment assembling apparatus is increased.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a segment assembling method and a segment assembling apparatus, in which a work load is reduced and work efficiency is improved, a pair of wing segments and a column are accurately connected, and strength is improved. Making high wing segments applicable, reducing the manufacturing costs of the segment assembling device, etc.
