摘要： PROBLEM TO BE SOLVED: To provide a segment structure for a shield lining which reduces ring deformation and can simplify a segment joint structure by employing a structure that copes with the bending moments of tunnel cross-sectional forces, and which can reduce increases in amount of reinforcement and height of a segment beam even under load conditions wherein bending is predominant, by reducing increase in burdens on a body, by virtue of the splicing effect of segment rings. SOLUTION: A segment ring comprises four segment 1, 2, 3, 4 parted from one another at positions near points O1, O2, O3, O4 where the bending moments of tunnel cross-sectional forces become zero. Between the segment rings, the joint positions of the segments 1-4 are staggered making the positions O1, O2, O3, O4 as reference points where the bending moments on the tunnel cross section become zero.

摘要： PROBLEM TO BE SOLVED: To dispense with a secondary lining, and improve the corrosion resistance by forming a segment body with the concrete to which the anti-septic agent is added, and preventing a joint member in which butted end faces are joined with each other from being exposed to an inner surface of the segment. SOLUTION: An arc-shaped segment body 1 is formed of the concrete consisting of the inert compound made of metal or metallic oxide which does not affect the physical properties of the concrete though it impedes the growth of germs. When the segment body 1 is connected in a ring shape, a joint member (a tightening piece) 2 is inserted in a joint hole 5 and a joint groove 6 provided in a ring joining surface 1a to prevent the joint member 2 from being exposed to an inner surface 1c of the segment, and a secondary lining and a resin coating to protect the corrosion of the joint member 2 is dispensed with. The construction period and construction cost are reduced, and the cost for maintenance and repair of a tunnel can be reduced.

摘要： PROBLEM TO BE SOLVED: To realize a structure in which a joint member is not exposed on an inner face of a segment, change the rigidity of a joint part and its elasticity for external force arbitrarily as required, correspond to a large cross section of a tunnel, and provide the additional contact effect of rings. SOLUTION: In a segment 1, a joint hole 5 is provided on a ring join face 1a which is an end face in the axial direction of a tunnel, and a joint member 2A protrudes a pin part 4 at both ends to form one-end opened square. The pin parts 4 at both ends of the joint member 2A are fitted in joint holes 5 of the segments in which piece join faces 1b which are end faces in the peripheral direction of the tunnel are abutted, respectively, to connect the segments mutually. A groove 6 in which a part 3 other than the pin part of the joint member 2A is fitted is provided on the ring join face 1a. If the joint member 2A is in the shape of character H, rings can be connected.

摘要： PROBLEM TO BE SOLVED: To rapidly carry out a primary lining process of an excavated wall of a tunnel by eliminating segment connecting work by bolt insertion and fastening. SOLUTION: When a new segment 10SB is axially moved to the lining body 10 side from the most protruded (A) state of an engaging pin 17, provided in a supporting recessed part 15 of a stepped port 135 of the new segment 10SB, from the supporting recessed part 15 by energizing force of a spring 18, the engaging pin 17 interferes with the stepped part 135 on the lining body 10 side as shown in (B) so as to be recessed into the supporting recessed part 15. Further as shown in (C), when the new segment 10SB reaches a position of being almost completely fitted to the lining body 10, the engaging pin 17 is put in a state of being engaged with an engaging recessed part 16. The new segment 10SB is therefore connected in a state of being fitted to existing segments 10SA, 10SB.
