摘要： PROBLEM TO BE SOLVED: To manufacture many segments capable of being satisfactorily connected in a short time. SOLUTION: A frame 2 opened at its inner surface side is arranged on an outer peripheral surface of a ring-like inner form 13 obtained by assembling foam plates 14 in a circumferential direction to constitute a ring 11. Fixing bands 12 are wound on the outer periphery of the ring 11, and an urging force is radially inwardly given. A concrete is charged from an inlet 16 formed at an upper end of the form 13 through a hopper 17, and the charged concrete is filled in a concrete placing space surrounded by the frame 2 and the form 13. After the concrete is cured, a segment filled with the concrete in the frame 2 is removed from the form 13, cured in a curing yard in a manufacturing factory, and thereafter stocked in a stockyard.

摘要： PROBLEM TO BE SOLVED: To provide a segment capable of preventing fall of joint fittings even under tensile force applied to the joint fittings through a connecting fitting. SOLUTION: Joint groove parts are formed at joint faces 1a on both sides of a segment 1, and these joint groove parts are respectively provided with joint fittings 3 each having a pair of hook-shaped locking parts 6 with the ends formed as inwardly bent locking piece parts 5. A connecting fitting formed by providing both side parts of a plate-like fitting body with engaging parts disposed in engaging space formed between the locking parts 6 and engaged with the locking piece parts 5 is inserted in a through hole formed by the joint grooves, from one side in the state of making the joint faces 1a butt each other and opposing the joint fittings 3 to each other. The joint fittings 3 are therefore connected to each other to form a tunnel wall body. The joint fittings 3 on both sides are connected to each other by reinforcements 16 embedded inside.

摘要： PROBLEM TO BE SOLVED: To provide a connection tool which is simple in the structure and favorable in the workability. SOLUTION: Mutual segments are positioned close to each other and a connection tool 1 of one segment is inserted in a connection hole 7 of the other segment to bring the connection faces of both segments into contact with each other. A squashing cap 3 of the connection tool 1 butts against the hole bottom 7c of the connection hole 7 and it is squashed and respective deformable pieces 4b of a member 4 widening the diameter, which has been contracted at the front end and the diameter, are deformed to be tabular to increase the diameter and a squashed part A is formed in the large diametrical part 7d to be fixed to an engaging part 7b. As a result, the connection tool 1 can never be drawn out of the connection hole 7 and the connection of mutual segments is finished.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of a defective product while ensuring a good air bubble removing capacity due to a degassing sheet and to manufacture a segment at a low cost. SOLUTION: The form for manufacturing the segment has a form body 11 opened upwardly and a lid form 12 arranged so as to cover the upper opening part 11a of the form body 11 and is constituted so as to cast concrete in the space surrounded by the form body 11 and the lid form 12 to manufacture the segment. Degassing sheets 22 and 23 are provided to the gap between the lid form 12 and the form body 11. At this time, tensile force is applied to the degassing sheets 22 and 23. The operation for applying tensile force to the degassing sheets 22 and 23 is performed to lower fear such that the degassing sheets 22 and 23 are bent or embedded in concrete.
