The outer rails 2 and 3 are laid. The ends of the main truss members 4 and 4b slightly longer than the diameter of the rails 2 are movably mounted between the outer rails 2, and the inner truss 3 is formed between the main truss members 4 and 4b. The truck 9 on the temporary roof A having the fan structure is movably mounted. After the excavation of the underground cylindrical part is completed, construction work for constructing a concrete skeleton 1a on the inner surface of the cylindrical part 1 serving as a storage tank, construction work for stretching a cold insulator on the inner surface of the concrete skeleton 1a, and applying a membrane material to the surface of the cold insulator. During the construction phase, the temporary roof A runs on its own during rainy weather or hot summer weather, and covers the upper part of the opening.
The above various construction works are performed in an all-weather environment in which rainwater intrusion or sunshine is prevented. Then, when the work of stretching the membrane material is completed, the temporary roof A is dismantled and removed, and a roof structure is constructed on the upper portion of the opening of the storage tank by a conventional method. In the construction work, a truck is provided at an arbitrary position in the storage tank by a self-propelled carriage 16 having a hoist crane 15 provided on the main truss members 4, 4b, in combination with the self-propelled means of the main truss members 4, 4b.

(A) During the construction period of the cylindrical underground structure, no work days due to rain can be eliminated, and the construction period can be greatly reduced. (B) Since the temporary roof has an extendable fan structure, it can be stored compactly when the upper part of the opening is opened, and the work in and out of the work site is not restricted and the workability can be improved. (C) In addition, since the temporary roof is slightly larger than the circular opening and has the same shape, the site can be used effectively. (D) By forming the main truss members at regular intervals and arranging a temporary roof between the main trusses, the upper opening of the excavated cylinder can be quickly opened and closed. (E) Two sets of inner and outer rails are separately laid on the outer peripheral ground part of the excavated cylindrical part, a drive truck of the main truss material is mounted on the outer rail, and a temporary roof is mounted on the inner rail. Is movable so that both ends of the temporary roof can intervene below the main truss material, and the rain can be simplified. (F) By extending both ends of the main truss material to the outside from the outer rail and providing a self-propelled bogie equipped with a hoist crane in the middle stage of the main truss material, the movement of the main truss material is improved. In conjunction with this, it is possible to carry in and out various equipment and materials to and from the excavated cylinder part at will.
Construction workability can be improved. (G) Since the roof frame members that make up the temporary roof are wires connected to the electric winch mounted on the bogie, the roof bone can be reduced in weight and the shape of the temporary roof can be improved, and the temporary roof can be disassembled. , Assembly is easy.
