Description of the Related Art When constructing a concrete arch structure, a plurality of hollow tubular arch-shaped supporting steel materials are bridged in parallel with each other by supporting the end portions on the support surfaces at both ends of the arch structure to be constructed. There is a method of constructing a concrete arch structure in which the supporting steel material is used as a core and the outer wound concrete is sequentially placed on the outer side thereof from both ends of the arch of the supporting steel material toward the top. (Japanese Patent Publication No. 60-15763). This method has the advantages that it requires less temporary equipment for installation, has good workability, and is easy to manage. In this method, the wagon is fixed on the existing concrete wound around the supporting steel material, the concrete formwork of the other side is held using this wagon, concrete is poured, and the wagon is transferred to the placed concrete. Since the concrete pouring of the other side is sequentially performed, a heavy-structured wagon with high rigidity was used.

The arch center is pre-assembled and installed in the space above the arching construction planned position, the concrete form moving support device is placed on the arch center, and the concrete form for arch ring block construction is hung from this support device. There is a technique of placing concrete inside and constructing an arching block, and after hardening the concrete, supporting the concrete by the arch ring hanging material hung from the arch center and moving the demolded formwork with a moving support device. It is disclosed. In this method, after the arch ring is completed, the arch ring hanging material is removed from the arch center, and then the arch center is dismantled.

It is completely different from the technique disclosed in Japanese Patent Publication No. 60-15763 described above in that it is suspended from the center. Since the work carriage used in this method runs on the arch center, the tilt of the carriage changes, but the supporting end of the vertical suspension material is a cylindrical surface support part so that the formwork is always suspended according to the change. have. In this work trolley, when the concrete is suspended and the concrete is placed, the weight of the concrete is borne by the trolley, and therefore the trolley of the trolley has to have a heavy structure. Also,
The wheels cannot bear this load, and a large number of liners are arranged on the arch center, and the underframe of the work vehicle is placed directly on the arch center via these liners.
The wheels are used only when moving the formwork, and are designed to run on the arch center.
