[Prior Art] Conventionally, in road or railway tunnel construction, a primary lining is applied by attaching segments to the wall after excavation, and then concrete called invert is placed on the bottom surface to improve the surface. Various facilities were installed on the invert so that it was smooth. In order to ensure a wide tunnel width, it is desirable to provide the floorboard near the diameter of the tunnel. For this reason, as shown in Figure 7 of the attached sheet, a lower concrete (2) was cast to a position close to the diameter of the tunnel (1), and a floor (3) was constructed above it.

[Problem to be solved by the invention] As mentioned above, conventionally, the floor part (3) was formed by pouring the lower concrete (2), but in large diameter tunnels, a large amount of concrete was poured. Since concrete was used, there were defects that resulted in extremely large material costs and man-hours. For this reason, in order to solve the above-mentioned problems and to utilize the underground space for ventilation grooves, power lines, communication lines, etc., we constructed a construction method in which an inner wall, etc. was erected on the lower surface of the tunnel (1), and a floor plate was installed on the upper part. Laws are being developed. This construction method can reduce the amount of concrete used because it secures a space below the floorboard. A secondary lining must be applied. However, after setting the formwork in the lower half arch and pouring concrete, the work of dismantling the formwork and setting a new formwork at the next pouring position is difficult.
It required a lot of manpower and was time consuming.

Next, the end plate (A) is set in the lower half arch part 0O of the front end face of the formwork θ, and concrete is poured from the gap between the formwork (one upper end part (15a) and the segment ring 00). . Then, check the hardening state of the concrete through the inspection holes (a) and (g) provided at appropriate locations on the formwork (+!lft), and after the concrete has hardened, remove the end plate (a) and The bolt (c) that secures the rail (!■0■

In this example, the lower end (+5b) of the formwork O0 is made of a separate member.
Since it is divided, when the jacks (I7) (I7)... are contracted, the lower end (+5b) slides diagonally and is drawn toward the reinforcing material (18c) as shown in Figure 3. 15c), peels off from concrete (a). Then, extend the horizontal movement jack (c) and extend the upper frame (a).
If it is moved inward, the entire formwork 0 is peeled off as shown in FIG. 5(C). Incidentally, if a release agent is applied in advance to the side surface of the lower half arch portion 0O of the formwork θ and concrete is poured, the removal will be made easier. Here, if the motor (c) is reversed and the pinion gear (a) is driven, the frame (4) of the traveling device (2) will move forward because the rail θ■ is fixed to the support member (fence). Therefore, the entire 0 formworks connected to this frame (G) are shown in Figure 5 (
As shown in b), move along rail 0■ to the tip of the existing concrete (a). Then, concrete is poured again as explained in Figure 5 (→).
