PURPOSE:To increase curve-workability, by moving forward a cylindrical transfer plate provided in the inside of a cylindrical table plate after a cut-off water plate is provided at the outside and concrete is placed and by forming a clearance on the outer periphery of the lining. CONSTITUTION:A cylindrical shield tail plate 20 is provided at the rear end of a skin plate 12 through a middle folded part 18. Next, a cylindrical transfer plate 40 is provided by use of a transferable jack 42 to be movable in the axial direction in the inside of the plate 20. Next, after a cut-off water plate 38 made of FRP or the like is arranged inside the plate 40 to be cylindrical. an inner mold frame 24 is assembled in the inside thereof to place concrete. And at the time when the concrete is cured as a lining to some extent, the plate 40 is moved forward to form a clearance between the plates 20, 38. In this way, a curved part can be constructed smoothly and promptly without interference with the lining and it can stand against a high hydraulic pressure atmosphere.
