摘要： PURPOSE:To provide a renewing pipe for lining an existing pipe capable of being uniformly expanded in diameter, holding a smooth inner peripheral surface even after the expansion of a diameter and good in the close adhesiveness with the existing pipe and to line the existing pipe using the renewing pipe. CONSTITUTION:A renewing pipe A is formed by covering a resin pipe composed of a thermoplastic resin with an outer layer 2 having at least one resin foam layer composed of a thermoplastic resin. An existing pipe 3 is lined by inserting the renewing pipe A in the pipeline of the existing pipe 3 to hermetically seal both ends thereof and introducing a heating fluid into the renewing pipe A under pressure to expand the diameter of the renewing pipe A while heating and softening the renewing pipe A to closely bond the renewing pipe a to the inner surface of the existing pipe 3.

摘要： PURPOSE:To provide a renewal pipe for a gas pipe, which is used for a lining construction method for an existing gas pipe and where gas to be transported cannot be leaked. CONSTITUTION:A renewal pipe A for a gas pipe comprises a resin pipe 1, a hot melt adhesive layer 2 covering the outside of the resin pipe 1, and a gas barrier layer 3 covering the outside of the hot melt adhesive layer 2. The hot melt adhesive layer 2 is brought into not-contact with the resin pipe 1 and/or the gas barrier layer 3, and is inserted into an existing gas pipe, where a diameter of the layer 2 is enlarged for use while being softened with heat.

摘要： PURPOSE:To provide a renewal pipe having superior diameter expansion and continuity for lining a deteriorated gas pipe, etc. CONSTITUTION:The outer surface of a noncrosslinking thermoplastic resin pipe 2 is covered to a predetermined thickness with a crosslinking thermoplastic resin layer 3. Thus the crosslinking thermoplastic resin layer 3 prevents the pipe from destruction in expanding its diameter. Applying thermal fusion to the noncrosslinking thermoplastic resin pipe 2 assures easy connection.

摘要： PURPOSE:To obtain a lining technique in which when a lining resin pipe is made of a crystalline thermoplastic resin, an inner face of a pipe now in use is lined with the resin pipe with the inhibition of the shrinkage of the resin pipe. CONSTITUTION:In a lining technique for an inner face of a pipe in use, a lining resin pipe made of a crystalline thermoplastic resin is inserted into a pipe line of an installed pipe 4, thereafter being softened and expanded in diameter to be brought into close contact with the inner face of the pipe. In this technique, the both ends of the expanded-diameter resin pipe 1' are sealed with tapered inner pipes 8a, 8b, and an internal pressure us applied by a heating fluid. While this state is maintained, a heating means 14, i.e., either an infrared radiation generator or a dielectric heater, is swept from one end 1a of the expanded- diameter resin pipe 1' to the other end 1b thereof to successively heat the resin pipe 1' to at least the melting point of the resin forming the resin pipe from the end 1a of the expanded-diameter resin pipe 1' to the other end 1b thereof.

摘要： PROBLEM TO BE SOLVED: To surely form a lining layer to a joint section for a segment in a short time while sufficiently following up to the movement of the segment by an earthquake and land deformation and surely conducting a cutoff. SOLUTION: A backup material 8 formed of a soft porous resin film is inserted into a joint groove 5 between the segments 2 while being opposed to the groove base of the joint groove 5. The internal surfaces of the segments 2 and the side faces of the joint groove 5 are coated with a polyurea resin, and lining layers 6 in which the corner sections of the joint groove 5 are rounded are formed. A section up to the backup material 8 is filled sufficiently with a viscous polyurea resin composition in the same system as the lining layers 6 and a sealing member 9 is formed into the joint groove 5, and the adhesive strength of the lining layers 6 and the sealing member 9 is increased.
