摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a resin-coated segment for shield tunnel simple in manufacture and high in water-tightness, service life, and strength, and a shield tunnel formed of resin-coated segments. SOLUTION: A form work is prepared for manufacturing a resin-coated segment formed of a bottom part form work 21 having at least one curved surface, side part form works 22 and 23 movable along the bottom part form work 21, and an upper part form work 24 having a concrete filling hole 241. A resin member 25 having at least one curved surface is installed on the inner peripheral surface of the form work. Then, a cure type adhesive agent 26 adherent in water or wet state is applied onto the surface of the resin member 25. A concrete 27 is placed into the form work before the cure type adhesive agent 26 is completely hardened or when it is in a semi-hardened state. After the concrete 27 is hardened, the resin-coated segments are removed.

摘要： PROBLEM TO BE SOLVED: To provide a reaction receiving structure of a tunnel branch part, which allows smooth boring to be performed by respective shield machines for boring unit tunnels branching off from a large section tunnel. SOLUTION: Reaction receiving bodies 11 for obtaining propulsive reactions of the shield machines 1 and 2 for boring the unit tunnels B and C, respectively, are provided, in the branch part (1) wherein the unit tunnels B and C branch off from the large section tunnel A so as to be bored. The body 11 is composed, in a framework-like manner, of upper and lower horizontal materials 12 and 13 which are installed along an axial direction of the tunnel A inside steel shell concrete installed in a ceiling part (2) of the tunnel A and a roadbed part (3) thereof, respectively, a plurality of supports 14 which are erected to the side of the unit tunnels B and C between the materials 12 and 13, and a plurality of diagonal members 15 which are installed between the support 14 and the material 12 and between the support 14 and the material 13.

摘要： PROBLEM TO BE SOLVED: To provide a joint structure for steel segments, which can connect ends of main girders of the adjacent steel segments to each other, and can very efficiently cover the natural ground of a large sectional tunnel.
SOLUTION: According to the joint structure, both the steel segments 1 each consisting of the plurality of main girders 2 and a skin plate 4 set on the natural ground side of the girders, are connected together by welding. At this time, the ends of the main girders 1 are connected together by welding. Then, cutoff ribs 4a are formed at edges of each skin plate 4 in a manner being spaced away from an edge of the main girder 2, and a sealing material 8 formed of rubber is interposed between the cutoff ribs 4a, 4a of the adjacent skin plates 4.
