2. Description of the Related Art Conventionally, in a shield method, an injection hole formed over the front and back of a segment constituting a cylindrical wall into a space called a tail void formed between the cylindrical wall and an excavation hole. By filling and filling a backing material such as mortar from the ground, the loosening of the ground due to the falling of the ground is prevented. In addition, the tail void becomes large especially in a steep curve lining location where the direction of excavation changes abruptly.If such a large tail void is filled with the backfill material at high pressure, this backfill material flows out from the tail void. There was a risk that it would flow into the excavator. Also, if the injection pressure of the backing material is suppressed in order to prevent the backing material from flowing into the excavator, the filling pressure of the backing material will be insufficient and the adhesive strength between the segment and the ground will be reduced, and the tunnel will be damaged. Deformation could occur.

[0003] For this reason, in recent years, a predetermined ring constituting a cylindrical wall body, and a ring constituted by a segment with a bag provided with a rubber bag on the outer surface side are being used. That is, a ring formed by connecting the bag-attached segments in the circumferential direction is arranged at predetermined intervals to form a tubular wall body, and each bag of the bag-attached segment is filled with grout to inflate. By closely contacting the outer circumference with the inner surface of the excavation hole, the tail voids are divided into predetermined ranges, and the divided tail voids are filled with the backing material.

However, since the above-mentioned bag-equipped segment is a rubber bag pre-installed at the factory, it causes weight increase of the segment, and the efficiency of its transportation and moving work is increased. There was a problem that it would decrease. In addition, the bag may be damaged or damaged during such transportation and moving work. In addition, there is a problem that a mold is required to manufacture the rubber bag, which increases the manufacturing cost. In addition, when the grout is filled into the bag, there is a disadvantage that the air inside is not discharged well.

Next, the lining work of the tunnel using the segment 1 with a bag will be described along the procedure. (1) In the excavation hole excavated by the shield machine,
As shown in (1), a ring 12 is assembled by connecting the bagged segment 1 and the normal segment S in the circumferential direction, respectively, and these rings 12 are connected in the axial direction of the excavation hole to form the cylindrical wall body 13. At this time, the rings 12 made of the bag-attached segment 1 are arranged at a predetermined interval. Here, when the segment 1 with a bag is installed together with the normal segment S as described above, the fastener 5 that attaches the segment body 2 and the bag 3 of the segment 1 with the bag is attached.
However, since the joining force is enhanced by being provided over the entire length of the long side on the rear side in the excavating direction, the bag body 3 is surely prevented from being turned over by the tail seal of the shield machine.

(2) Then, the instant connection type grout 11 is injected from the injection hole 4 of the segment body 2 of each bag-equipped segment 1. In this way, as shown in FIG. 7, the grout 11 is injected into the space between the bag member 7 and the sheet member 6 forming the bag body 3 through the injection hole 4, and the bag 3 is filled with the tail void. It expands in T and the sheet member 6 is pressed against the natural ground G and comes into close contact with it. At this time,
In the bag 3, the bag member 7 has air permeability.
When the grout 11 is injected, the air inside gradually escapes to the outside, and no air remains in the bag 3.

As described above, if the segment with bag 1 is used, the tail void T formed between the ground G and the cylindrical wall body 13 is partitioned by the bag body 3 in the axial direction at a predetermined interval. However, since the backfill material 14 can be injected into the divided tail voids T, the backfill material 14 is filled with high pressure even at a sharp curve lining site where a large tail void T is formed. be able to. Therefore, it is possible to secure a reliable adhesive force between the cylindrical wall 13 and the ground G, and it is possible to reliably prevent the tunnel from being deformed due to insufficient filling pressure of the backing material 14.

Further, since the bag 3 is detachable from the segment body 2 by the fastener 5, the bag 3 can be removed at the time of carrying or moving operation. That is, compared to a bag-attached segment in which a conventional rubber bag is attached in advance at a factory or the like, transport and movement can be performed at a reduced weight of the segment at the time of work, and labor can be reduced. Breakage and damage of the bag 3 can be prevented. Also, compared to rubber bags,
The weight can be reduced, and the manufacturing cost can be significantly reduced by eliminating the need for a mold for manufacturing. Furthermore, since the bag member 7 having air permeability is used, air can be vented when the grout 11 is injected, as compared with a rubber bag.

Here, what is shown in FIGS. 9 and 10 is a segment body 2 having a shape other than a rectangular shape in plan view, such as a key segment. Specifically, what is shown in FIG.
Both sides thereof are gradually narrowed toward the front side in the excavation direction (arrow A direction in FIG. 9). In the case of the segment main body 2 of this shape, the fastener is provided over the entire long side on the rear side in the excavation direction. By providing 5, it is possible to prevent the bag body 3 from being turned up due to the tail seal of the shield machine. In the case shown in FIG. 10, both sides are gradually widened toward the front in the digging direction (the direction of the arrow A in FIG. 10). By providing the fastener 5 over the entire long side and the entire short side on both sides, it is possible to reliably prevent the bag body 3 from being turned up by the tail seal of the shield machine.
