Or penetrating inside the corner element 30;
Alternatively, the ground near the external communication opening 14 or 24a, 24b or the external communication opening (not shown) of the corner element 30 can be prevented from collapsing.

Therefore, the retaining plate 50
When mounted on the reference element 10, it protects the surrounding soil and the like from flowing into the reference element 10 from the external communication opening 14 and can function as a temporary earth retaining member for supporting earth pressure. it can. For this reason, if an auger drill or the like is provided inside the reference element 10,
The reference element 10 can be inserted into the ground while excavating and removing earth and sand or the like at the element tip or inside.

Next, as shown in FIG. 4A or FIG. 4C, another retaining slide plate 50 (the retaining slide plate mounted on the reference element 10) is provided on the outer side of the connecting element 20.

This allows
The retaining slide plate 50 that has been fitted on both sides of the reference element 10 is slid slightly in the axial direction of the element and pushed out.

Thereafter, the excavation and insertion are performed by an auger or the like with the element axial direction as the insertion direction, so that the connecting element 20 is guided and inserted by the reference element 10 and inserted. As a result, the reference element 10
The retaining slide plate 50 fitted on both sides of the

The outermost connecting element to be newly connected (not shown)
Is slightly pushed in the element axial direction, so that the tip of a new connecting element (not shown) is further left of the left connecting element 20 shown in FIG. 5 and further right of the right connecting element 20 shown in FIG. Can be fitted. As a result, the retaining slide plate 50 that has been fitted on both sides of the left and right connecting elements 20 is used.
Is slightly pushed out in the axial direction of the element.

Thereafter, by performing excavation and insertion with an auger or the like with the element axial direction as the insertion direction, the outermost connecting element (not shown) to be newly connected is shown in FIG.
Is guided and inserted by the connecting element 20. Thereby, the retaining slide plate 50 that has been fitted to the outside of the connecting element 20 in FIG. 5 (the left side of the left connecting element 20 and the right side of the right connecting element 20) is newly connected. The outermost connecting element (not shown) slides by the inserted amount and is pushed out in the element axial direction. In this way, the tip of the newly connected outermost connecting element (not shown) reaches the reaching position.

It will be completely pushed out in the axial direction and will be removed from the left and right connecting elements 20.

By repeating the above steps, as shown in FIG.
The zero and corner elements 30 can be connected underground, thereby forming an element structure E. At this time, as the retaining slide plate attached to the outer side of the element newly connected to the outermost side, the retaining slide plate previously removed from the other element can be diverted. Alternatively, a completely new retaining slide plate may be used.

Next, concrete is poured into the inside of each of the elements 10, 20, 30 and hardened. In this case, the reference element 10 and the connection element 20 of the present embodiment
Has external communication openings 14, 24a and 24b, so that if concrete is poured into any element, the concrete flows into the adjacent element,
Further, it flows into the adjacent outer element and spreads over the whole. Therefore, there is an advantage that concrete can be cast at once.

Next, an element structure in which concrete is cast inside each element is used as a protective work, and the ground at a portion surrounded by the element structure is excavated.
Thereby, the tunnel 101 is constructed.

The present invention is not limited to the above embodiment. The above embodiment is an exemplification, and has substantially the same configuration as the technical idea described in the scope of the claims of the present invention. It is included in the technical scope of the invention.

For example, in the above embodiment, the upper plate of the reference element 10 and the connecting element 20 is a first fixed plate, and the lower plate of the reference element 10 and the connecting element 20 is a second fixed plate.
Although the example in which the plate on the left side of the corner element 30 is the second fixed plate has been described, the present invention is not limited to this example, and may have another configuration, for example, a configuration reverse to the above.

The invention is not limited thereto, and a tunnel construction lining element having another configuration, for example, a tunnel construction lining element having a substantially “U” -shaped cross section may be used. These may be used in an appropriate combination.

In the above embodiment, an example was described in which the plate connecting member of the reference element was a columnar member and the plate connecting member of the connecting element was a truss oblique member. However, the present invention is not limited to this example. Alternatively, a lining element for tunnel construction having another configuration, for example, in contrast to the above, the plate connecting member of the reference element may be a truss oblique material and the plate connecting member of the connecting element may be a columnar member. Alternatively, both may be columnar members, or both may be truss diagonals. The same applies to the corner element.

In the above embodiment, the retaining slide plate has two plate-like members (slide plates 51 and 52) and two retaining slide plate joints (53). Although the example which was constituted in the shape of a hollow box with a cross section was explained, the present invention is not limited to this example, and the retaining slide plate of another constitution, for example, one plate-shaped member (slide plate), Two retaining plate joints (5
The slide plate for retaining may be provided with 3) and configured as a beam having a cross section of an “I” shape as a whole.
