摘要： PROBLEM TO BE SOLVED: To provide a reinforcing member for a helical pipe, which can be applied to a joiner, and in which back filling material can be filled in the whole space between an inner surface of a sewer pipe and the helical pipe, and a method for constructing a regenerated pipe using that.
SOLUTION: As a first member 46 of the reinforcing member 10 is installed to cover two protruded parts 42 formed on the joiner 12, space 54, 56, and 54 is formed of the first member 46, the protruded parts 42, and a main body 34 of the joiner 12. Since an opening part 50 is formed in the first member 46, the back filling material 44 can be fed to all the space 54, 56, and 54 through the opening part 50. The regenerated pipe can thus be formed to have sufficient strength without forming a dent in an inner surface of the joiner 12. Since there is no dent in the inner surface of the joiner, no sewage is collected there. As the reinforcing member is installed on the joiner that is relatively light compared to a strip, the joiner, the strip, and the reinforcing member can be easily handled and carried.

摘要： PROBLEM TO BE SOLVED: To provide a reinforcing member for a helical pipe, which strongly reinforces the helical pipe, and in which back filling material is filled to the whole space between an inner surface of a sewer pipe and the helical pipe, and a method for constructing a regenerated pipe using that. SOLUTION: As the reinforcing member 10 is installed on a leg part 22 of a strip 16, space 54 is formed between a side wall part 48 of the reinforcing member 10 and a main body 20 of the strip 16, and the back filling material 44 is fed to the whole space 54 to be tightly applied to the leg part 22. The leg part 22 is held strongly by the back filling material 44. The reinforcing member 10 is placed on the leg part 22 of the strip 16 to be installed onto the leg part 22 without being elastically deformed. To prevent the leg part 22 from coming off the reinforcing member 10, the side wall part 48 of the reinforcing member 10 is caulked to be engaged with the leg part 22. As the leg part is strongly held by the back filling material, the regenerated pipe is formed with such strength as to prevent the strip from coming off the reinforcing member even by ground vibration or the like. As the reinforcing member is placed on the leg part to be installed on the leg part, labor of a worker can be reduced. For caulking the reinforcing member, a jig or the like is used, and burden on the worker is small. COPYRIGHT: (C)2004,JPO

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 secure water cut-off performance even in a pipe having a small groove in an outer circumferential face such as a spiral pipe.
SOLUTION: The rubber ring 10 includes a compressing part 40 and a lip part 42, and a plurality of recessed parts 46 are scatteredly formed on an inner circumferential face of the compressing part 40. By forming the recessed parts 46, a protruding part 48 is continuously formed between axial both end parts and each recessed part 46. In a rubber ring junction, the protruding part 48 is closely contacted to an outer circumferential face of the spiral pipe and the groove 22. Water from inside the pipe can pass the lip part 42 through the groove 22 but since the groove 22 is cut off by the protruding part 48, it can not advance in the groove 22 and it is accumulated in the recessed parts 46. Intrusion of water from outside the pipe is blocked by the protruding part 48 closely contacting the outer circumferential face of the pipe 14 and the groove 22.

摘要： PROBLEM TO BE SOLVED: To apply a rubber ring connection to pipes made of a polyolefin resin which tends to have turn of a rubber ring.
SOLUTION: The rubber ring installed on a rubber ring receiving part 12 of a rubber ring socket 10 includes a compressing part 14b received in a rubber ring receiving part 12 and a lip 14a extending from the compressing part 14b in the insertion direction of a spigot. A holding member 16 is fixed on the insertion side of the spigot of the rubber ring receiving part 12 to compress and retain the compressing part 14b of the rubber ring 14 between the same and the rubber ring receiving part 12. The holding member 16 prevents the rubber ring 14 from moving in the spigot insertion direction in the rubber ring receiving part 12. Consequently, turnoff the rubber ring 14 in the rubber ring receiving part 12 is prevented.

摘要： PROBLEM TO BE SOLVED: To easily and securely eliminate the chips by threading a screw part of an extruder with a screw hole of a hole saw, and after a tip of the extruder abuts on the chips, pushing the screw part more into a deep hole.
SOLUTION: A screw part 2a of an extruder 1 is threaded with a screw hole 18 of a hole saw 19 exposed by eliminating a shank, and a grip part 3 is rotated so as to insert the screw part 2a into the hole saw 19, and a tip 2b of a screw rod 2 abuts on a bottom surface of the chips 25. In this condition, the grip part 3 is rotated more in the progressing direction so that the screw part 2a is inserted more into a deep hole 16, and the tip 2b pushes the bottom surface of the chips 25 so as to extrude the chips 25 to an opening side of the hole saw 19, and extrudes the chips to a position out of the opening. The chips 25 is easily taken out of the deep hole 16 by the screwing force of the extruder 1.

摘要： PROBLEM TO BE SOLVED: To positively joint the pipe end of an insertion pipe to a socket of an electric fusion joint or a mechanical joint without correcting treatment in which the end part peripheral wall of the insertion pipe, which is recovered from a corrugated shape, has cylindrical shape close enough to a complete circle, and to smoothly insert the insertion pipe provided with the corrugated shape, into an existing pipe comprising a bent part, even if unheated.
SOLUTION: A circular pipe formed of synthetic resin is cooled. The circular pipe is reheated to a temperature from a softening point up to a fusing point, and in this state, the circular pipe is pressed to the inner surface of a molding die 16 to provide corrugated shape. Since the insertion pipe 10 provided with the corrugated shape has circular cross section perpendicular to the axial direction, if it is heated to the temperature of providing the corrugated shape, a peripheral wall is recovered into cylindrical shape equivalent to the original circular pipe close enough to the complete circle.

摘要翻译：要解决的问题：为了将插入管的管端积极地接合到电熔接头或机械接头的插座上，而不进行校正处理，其中从波纹状回收的插入管的端部周壁，具有足够接近整圆的圆柱形形状，并且即使未加热，也能将具有波纹形状的插入管顺畅地插入到包括弯曲部的现有管中。解决方案：将由合成树脂形成的圆形管冷却。将圆管重新加热至从软化点到熔点的温度，在该状态下，将圆管按压到成型模具16的内表面以提供波纹形状。由于具有波纹形状的插入管10具有与轴向垂直的圆形横截面，所以如果将其加热到提供波纹形状的温度，则周壁被回收成与原始圆形管相当的圆筒形状，足够靠近完整的圆圈。
