Therefore, conventionally, it is necessary to assemble components by assembling parts on the ground S at the construction site of the tunnel TN. Therefore, when assembling in the tunnel TN, an area for temporarily placing and arranging many parts on the ground inside the tunnel TN is required, and a crane is also used for the assembling. As a result, a large amount of space is occupied in the tunnel TN for assembly of the components. On the other hand, since no extra space is secured in the tunnel TN, as described above, when a large space is occupied, it is not possible to move vehicles such as trucks or perform other work during the occupied period. Gone. As a result, the construction period for tunnel construction is lengthened.

In the above configuration, the constituent members of the concrete formwork apparatus can be stably maintained in an upright state by the erector. Therefore, since the constituent member is stable in an upright state, it can be transported by a truck or the like without disassembling the constituent member into a plurality of parts. Therefore, at the tunnel construction site, it is possible to omit the space for temporarily placing the parts of the constituent members and for assembling the parts. Therefore, movement of trucks and other work in the tunnel is hardly hindered, so that the construction period of the tunnel can be shortened.

Further, in the structural member unit of the concrete formwork apparatus of the present invention, in the concrete formwork apparatus for forming the lining concrete of the tunnel, the lower end of the structural member extending in the extension direction of the tunnel is configured It is characterized in that the stand for standing the members is detachably attached.
Moreover, in the structural member unit of the concrete formwork apparatus of the present invention, the base body extends in a direction perpendicular to the longitudinal direction of the structural member.

Therefore, in the constituent member unit of this concrete forming apparatus, since the constituent members are stabilized as described above, the constituent members can be transported by a truck or the like without being disassembled as parts. Therefore, it is no longer necessary to assemble the parts at the tunnel construction site after delivery.

Further, in the concrete formwork apparatus for forming the lining concrete of the tunnel of the present invention, the erector is provided for erecting the structural member with respect to the lower end of the structural member extending in the extension direction of the tunnel.

By detachably attaching a stand for standing up the concrete formwork apparatus, the constituent member unit of the concrete formwork apparatus is configured, and the constituent member unit is arranged so that its longitudinal direction is along the front-rear direction of the truck bed. It is characterized in that the constituent member unit is conveyed while the constituent member unit is loaded on the loading platform using a stand for the constituent member as a leg.

Therefore, in the method of transporting the constituent member units of the concrete formwork apparatus described above, the constituent member units are loaded on the carrier of the truck so that the longitudinal direction thereof extends along the longitudinal direction of the carrier. Therefore, it is possible to prevent the component unit in the assembled state from protruding from the side of the loading platform. Therefore, since it is not necessary to disassemble the constituent members into parts and transport them, it is possible to omit the space for temporarily placing the constituent members and assembling the constituent members at the tunnel construction site. Therefore, the construction period for tunnel construction can be shortened.

Further, in the method for constructing a concrete formwork apparatus of the present invention, in the concrete formwork apparatus for forming the lining concrete of a tunnel, the constituent member is attached to the lower end of the constituent member extending in the extension direction of the tunnel. By detachably attaching an erecting base for erecting the concrete form apparatus, a constituent member unit of the concrete form apparatus is constructed, and the constituent member unit is erected on the side in the width direction of the planned construction area of the concrete form apparatus. After the temporary placement, the stand is removed, and the concrete forming apparatus is constructed from the constituent members.

Therefore, in this method for constructing a concrete formwork apparatus, the constituent members can be transported by a truck or the like without being disassembled. Therefore, the construction period for tunnel construction can be shortened. Moreover, since the constituent members can be used as they are for constructing the concrete form apparatus by removing the erector from the constituent member unit, the concrete form apparatus can be constructed smoothly. In addition, the constituent member units are temporarily placed in an upright state laterally in the width direction of the planned construction area of the concrete formwork apparatus. Therefore, it is possible to avoid obstruction of passage of vehicles such as trucks and forklifts passing through the central part of the tunnel and movement of goods by the temporarily placed component unit, which contributes to shortening the construction period of the tunnel.

Further, in the dismantling method of the concrete formwork apparatus of the present invention, when dismantling the concrete formwork apparatus, an erector is detachably attached to the lower end of the component disassembled from the concrete formwork apparatus, and the It is characterized in that the constituent members are temporarily placed laterally in the width direction of the installation position of the concrete formwork apparatus using the standing base as a leg.

In this dismantling method, the dismantled constituent members can be temporarily placed in an upright state laterally in the width direction of the installation position of the concrete formwork apparatus on the erecting stand. Therefore, when dismantling the concrete formwork apparatus, the constituent members can be placed temporarily without being an obstacle, so that the dismantling work can be carried out efficiently. In addition, after the constituent members are moved from the temporary placement position to the bed of the truck, they can be transported in an upright state without sticking out. Therefore, it is possible to shorten the work period for tunnel construction.
