摘要： PROBLEM TO BE SOLVED: To provide a joiner which does not come off a strip even if the pitch of the strip is widened, and the watertightness is retained.
SOLUTION: A belt-like strip 14 is spirally wound round on the inside surface of a sewer pipe 12. Side borders of the strip 14 are jointed by a joiner 10. When the pitch of the strip 14 is widened e.g. by earthquake ground motion, a body 32 is broken off at the part of a notch 42 by an external force which breadthwise expands the body 32, before the fitting of hollow bar 34 of the joiner 10 to strip grooves 22 of the strip 14 comes off. Thus, expansion of the pitch of the strip 14 can be allowed. Even if the body 32 is broken off and each side of the body 32 is separated from each other, the gap between the separated sides can be sealed watertightly by a flexible part 40.

摘要： PROBLEM TO BE SOLVED: To enhance workability without requiring connecting operation within an existing tube. SOLUTION: A method for regerating the existing tube comprises assembling an arc member and a connection member inside manhole etc. and then creating a plurality of ring body units 10. It comprises carrying them into the installed tube 32 in sequence and lining up without connecting the ring body unit 10 with each other. It comprises winding up a belt-like inside member 40 on inner surface of the ring body unit 10 after they are arranged and then forming inner surface of the regeneration tube. It comprises injecting a filling from above net-like spacer 34 between the belt-like inside member 40 rolled and the installed tube 32 and making the installed tube 32 in one piece with the ring body unit 10 and the belt-like inside member 40.

摘要： PROBLEM TO BE SOLVED: To reduce an inspection time for convenient performance and improve workability.
SOLUTION: A pipeline is closed and water is supplied into the pipeline. Excess pressure of 1.75 MPa larger than inspection water pressure is applied. After the excess pressure is applied, the excess pressure is immediately reduced to the inspection water pressure of 1.0 MPa without a holding time. Then, behavior of pressure deterioration is measured. If a first measured water pressure i.e., pipeline water pressure after 1 hour from application of the inspection water pressure is a first predetermined reference water pressure or more, it determines that there is no water leakage in the pipeline. The first reference water pressure is set to a value e.g. 0.95 MPa. If the first measured water pressure is below the first reference water pressure, the behavior of the pressure deterioration is continuously measured. If a second measured water pressure after 24 hours from the application of the inspection water pressure is a second predetermined reference water pressure or more, it determines that there is no water leakage in the pipeline. The second reference water pressure is set to a value e.g. 0.7 MPa.

解决方案：管道关闭，水管道中供水。施加比检查水压大1.75MPa的过压。施加过量的压力后，过剩压力立即降低到1.0MPa的检查水压，而没有保持时间。然后，测量压力劣化的行为。如果第一测量水压即施加检查水压1小时后的管道水压为第一预定参考水压或更高，则确定管道中没有漏水。第一参考水压被设定为例如值。 0.95MPa。如果第一测量水压低于第一参考水压，则连续地测量压力劣化的行为。如果从施加检查用水压力起24小时后的第二测定水压为第二规定的基准水压以上，则判断为在管路中没有漏水。第二参考水压被设定为例如值。 0.7MPa。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To easily perform construction without disassembling respective structural parts. SOLUTION: At least one slit 18 axially extending from the tip of an opening part 16 is formed on a joint main body 14, and a biting edge 24 is formed on the inner surface of a part formed with the slit 18, namely, a fastening part 20. Accordingly, when a fastening ring 34 is rotated and displaced to the fastening part 20 after a soft pipe 12 mounted with an inner core 42 on its end is inserted into the opening part 16, the fastening part 20 is contracted, the biting edge 24 on the inner surface bites the outer surface of the soft pipe 12, and the soft pipe 12 is pinched between the fastening ring 34 and the inner core 42.

摘要： PROBLEM TO BE SOLVED: To improve earthquake resistance of a conduit by absorbing stress generated on the conduit. SOLUTION: A ferrule with saddle 16 is attached to a water pipe 12, and an attaching port 24b formed on the ferrule with saddle 16 is faced in the axial direction of the water pipe 12. A straight pipe part 20a of an L-shaped feed water pipe attaching pipe 20 is connected to the attaching port 24b through a union joint 18. Since an expansion joint 38 is formed on the straight pipe part 20a, stress generated on a conduit when the water pipe 12 is axially displaced in absorbed in the expansion joint 38 by expansion of the conduit.

摘要： PROBLEM TO BE SOLVED: To sufficiently cope with the case where the relative displacement amount between a feed water pipe and a corporation stop with saddle is large as well as to constitute a feed water pipe connecting structure having a bending property and an expansible property at low cost.
SOLUTION: A feed water pipe attaching pipe 18 is inserted in an attaching part of a corporation stop with saddle of a feed water pipe 14, and the attaching part is wrapped. When the relative displacement is generated between the feed water pipe 14 and the corporation stop with saddle 16 by the ground displacement following an earthquake, a curved pipe part 46 of the feed water pipe attaching pipe 18 follows the displacement and bent or expanded or contracted.
