摘要： PROBLEM TO BE SOLVED: To produce segment main body having an anchor member on the inner surface at a reduced cost by a method in which a resin member containing a norbornene monomer and a metathesis catalyst system as a main materials is reaction-injection-molded to coat the inner surface of the main body and joining walls in the circumferential direction and the axial direction in a resin molding form, and cured thereafter. SOLUTION: Concrete is injected from a concrete injection port in the upper part of a segment main body molding lower part form in which an anchor pin 154 is embedded in advance, and a reinforced concrete segment main body is molded. After molding, the segment main body is moved onto a resin member molding base 21 in which the first and second resin molding side forms 22, 23 which are nearly of the same shape with a segment main body molding lower part form and separated from a joining wall are arranged. A norbornene monomer and a metathesis catalyst system from a resin member injection port 231, a main material reaction-injection molding resin member 25 is introduced, packed in the form, and cured to produce an inner surface resin-coated segment. As a result, a mold is inexpensive, and the segment in which the segment main body and the resin member can improve adhesion is made.

摘要： PROBLEM TO BE SOLVED: To obtain a resin-coated segment with a simple structure and superior water-tightness and, besides, with great pressure strength by filling concrete member into a thermosetting resin mold member comprising two connection surfaces and a bottom plate. SOLUTION: A thermosetting resin trapezoidal mold member 11 is constituted of a curved bottom plate 12, a ring side long side face 13, and a ring side short side face 14. Anchor pins 17... are provided at the bottom plate 12 for preventing separation of concrete material. Also, anchor ribs 18, 18, 19, 19 are integrally molded for preventing separation of concrete material at the bottom plate 12, ring side long side face 13, and ring side short side face 14. In addition, a resin-coated segment is constituted by filling concrete material into the mold member 11, and a shield tunnel is constructed by assembling a plurality of segments. In this manner, resin-coated segments can be obtained which have a simple structure, superior water-tightness, and a strength sufficient to maintain the compression of a tunnel.

摘要： PROBLEM TO BE SOLVED: To curtail the cost of a mold for molding and reduce manufacturing cost by using a preformed segment body made of reinforced concrete as a part of forms for molding a resin member in a resin-member coated segment in combination. SOLUTION: A preformed segment body 15 is transferred to a base 21 for molding a resin member, and first and second side-section forms 22, 23 for molding the resin member are arranged at intervals from connecting walls. Forms are disposed even on the connecting wall sides in the axial direction of the segment body 15 and a top force 24 on the upper side. When the resin member 25 is pressed in from a filler hole 231, air is vented from an air vent hole 241 and the inside of the forms are filled. The segment body 15 and the resin member 25 are fast stuck and held in by anchor pins 154, and the resin member 25 entered into notched sections 153 for forming the member is shrunk on curing and is difficult to be peeled from the segment body 25. The cost of forms is reduced by using the segment body 15 as the inner mold of the resin member 25.

摘要： PROBLEM TO BE SOLVED: To reduce cost, by integrally forming a reinforced concrete segment with a curved resin member provided with bolt boxes, through anchorage members. SOLUTION: A concrete member 12 is molded with a form on a curved thermosetting resin member 11 integrally provided with bolt boxes 13 to constitute a segment 1 coated with the resin at the inside face. And anchor pins for prevention against peeling of the member 12 are fitted to the member 11 and embedded in the member 12 together with a steel rod cage or the like. The bolt box 13 is used for a bent bolt. Fiber reinforced plastic comprising a sheet molding compound or a material for reaction injection molding chiefly comprising norbornane monomer and metathesis catalyst, are used for the thermosetting resin. The box 13 can be closed by a circular cover 151. In this way, the cost of the metal mold and the segment can be reduced. And an excellent sewage shield tunnel can be constructed owing to the watertightness and the chemical-resistance.

摘要： PROBLEM TO BE SOLVED: To construct a tunnel in a simple execution at low costs by continuously setting rings being circumferentially stacked one by one with substantially trapezoidal resin coated segments to be changed alternately in its direction in the axial direction of the tunnel. SOLUTION: A recess part is formed by providing an outer frame for concrete on a substantially trapezoidal frame member 11 comprising a curved bottom plate 12 made of thermosetting resin, a ring side long side face 13, and a ring side short side face 14. Filling of concrete in the recess part constitutes a substantially trapezoidal resin coat segment. The substantially trapezoidal resin segment 1 is stacked successively in the circumferential direction being changed alternately in its direction to form a ring. Next, a tunnel is constructed by continuously setting these rings in the axial direction of a tunnel. As a result, a tunnel can be constructed by one kind of segments, thus the execution can be done with ease at low cost.

摘要： PROBLEM TO BE SOLVED: To obtain a film simultaneously satisfying all of flexibility, tensile strength, elongation, tear strength, etc., by using a resin material containing a resin component mainly consisting of a polyesteramide resin containing aliphatic ester structures and aliphatic amide structures. SOLUTION: This film is one having a thickness of 15-100 μm and prepared by e.g. the extrusion molding of a composition comprising 100 pts.wt. polyesteramide resin having an average molecular weight of 10,000-300,000 and containing aliphatic ester structures and aliphatic amide structures, 0.01-1.0 pt.wt. hindered phenolic compound or phosphorous ester compound, 0.01-1.0 pt.wt. hindered amide light stabilizer, 0.5-50 pts.wt. inorganic filler (e.g. silica) or colorant, and additives such as a plasticizer, a lubricant, and a reinforcement. The polyester amide resin is produced by mixing an aliphatic aminocarboxylic acid or aliphatic aminocarboxylic acid or an aliphatic lactam with an aliphatic dicarboxylic aid and an aliphatic diol and subjecting the mixture to a dehydration reaction, and polymerizing the dehydrated mixture in a vacuum.
