摘要： Segments each having side plates 102 and 103 and a plurality of inner plates 106 and 107 inside the side plates are coupled in the circumferential direction and in the longitudinal direction to construct a rehabilitation pipe inside an existing pipe. A plastic nut retainer 50 for retaining therein a nut 60 engaged with a coupling bolt 11 is attached between the side plate 102 on one side of the segment 1b and the inner plate 106 adjacent thereto. The coupling bolt is screwed into the nut co couple the segments 1a and 1b in the longitudinal direction due to clamping by screwing. A groove is formed in the nut retainer, and the nut is press-fitted into the groove and retained in the nut retainer.

摘要： A linking pin made of elastic plastic having linking pin halves is used to link segments in the longitudinal direction to assemble a rehabilitation pipe. The linking pin includes a tubular portion having on its outer periphery surface first and second protrusions separated by a distance of twice the thickness of the side plate of the segment and a rear protruding portion that enlarges in diameter due to elasticity. The linking pin is inserted into one segment and the other segment so that the side plates of both the segments come between the first and second protrusions. The linking pin is then enlarged in diameter due to elasticity to fit the side plates between the first and second protrusions and link both the segments in the longitudinal direction. The linking pin that is enlarged in diameter can be reduced in diameter to unlink both the segments.

摘要： Segments are linked in the circumferential length to assemble a pipe unit, which is linked to another pipe unit using a link bolt to install a rehabilitating pipe inside an existing pipe. An elastically deformable clip having a cylindrical cavity with a notch is attached to the link bolt between the inner plates of the segment. The clip grips the link bolt at the cavity thereof that is enlarged due to elastic deformation. When the link bolt is moved in the direction opposite the insertion direction, the clip that grips the link bolt hits the inner plate of the segment to limit the movement of the link bolt in the opposite direction and prevent the link bolt from falling out of the segment.

摘要： Segments are linked in the circumferential and pipe length directions to install a rehabilitating pipe inside an existing pipe. Each of the segments comprises an inner surface plate, side plates provided upright on both sides extending in the circumferential direction of the inner surface plate, and inner plates provided upright between the side plates. A plurality of nuts is secured to the segments along the circumferential direction thereof. A linking member that can be screwed into the nut is prepared and inserted into a segment. The segment into which the linking member is inserted and the segment to which the nut is secured are aligned into contact with each other, and the linking member is screwed into the nut to fasten both the segments together and link them in the pipe length direction. A temporary lock is mounted on the segment to prevent the inserted linking member from falling out from the segment.

摘要： A tubular lateral pipe lining material is configured to be inserted into a lateral pipe which intersects with a main pipe in order to repair the lateral pipe. The tubular lateral pipe lining material has a flexible tubular resin-absorbing material impregnated with an uncured curable liquid resin. The tubular resin-absorbing material has one end that is folded back. A flange member, over which the folded-back end of the tubular resin-absorbing material is pressed, is made of a thermoplastic resin. An adhesive is applied over the flange member and the folded-back end of the tubular-absorbing material to bond the tubular resin-absorbing material to the flange member.

摘要： A segment for a rehabilitation pipe comprises an inner surface plate constituting an inner circumferential surface, and side plates and end plates provided upright on a peripheral edge of the inner surface plate. The plates are formed integrally from a plastic material and the segments are linked in a circumferential direction and in a pipe-length direction to install a segmental rehabilitation pipe inside an existing pipe. Each side plate is provided in the vicinity of the end plate with an opening used for a linking operation of the segments in the circumferential direction. It is possible to insert a linking member through the opening and readily link the segments in the circumferential direction. The opening formed in the side plate enables filler material injected into the space between the existing pipe and the segmental rehabilitation pipe to flow in or out through the opening.

摘要： An auxiliary tool comprises a body formed of a core material and an elastic cloth covering that covers the surface of the core material. The body is configured for insertion into a pipe ahead of a fluid used to fill the pipe so that during filling of the pipe the flow of the fluid advances the body through the pipe to force out and discharge from the pipe air existing ahead of the body while the body is advanced inside of the pipe.

摘要： A cutting apparatus cuts a lateral wall of a manhole to form a hole on the lateral wall of the manhole. A circular pipe is harmonized with a main pipe and fixedly disposed therein. A rotary ring configured so as to be able to rotate along the periphery of an opening in the manhole about the axial center of the main pipe is mounted on the circular pipe. A pressurized fluid material or pressurized granular material is sprayed from a nozzle held in the rotary ring. The rotary ring is rotated and the lateral wall of the manhole is cut through along the periphery of the opening in the manhole by the fluid material or granular material sprayed from the nozzle. Since the cut portion is shaped as a circle symmetrical about the axial center of the main pipe, it is possible to form a circularly shaped cut-through part centered along the periphery of the opening in the manhole without accidentally breaking or damaging the lateral wall thereof.

摘要： A lateral pipe lining material having a tubular resin-absorbing material impregnated with a thermosetting resin is inserted through a main pipe into the lateral pipe. The lateral pipe lining material is provided with a pushing-up member to push up a collar formed at its end of the lateral pipe lining material. When the lateral pipe lining material is drawn into the lateral pipe to the extent that the collar reaches an opening of the lateral pipe, the pushing-up member is lifted to bring the collar into close contact with the lateral pipe opening periphery of the main pipe. The lateral pipe lining material is then expanded and a heating medium is applied thereto to cure the resin impregnated in the tubular resin-absorbing material. The lateral pipe lining material can be drawn smoothly into the lateral pipe even when it is bent, enabling the lateral pipe to be lined with a high quality.

摘要： An auxiliary tool comprises a core material covered on the surface with an elastic cloth. The auxiliary tool is inserted into a pipe having curved and bent parts and a fluid is injected into the pipe. Since the cloth covering is elastic and flexible, the auxiliary tool passes through the ridges of peaks in the pipe while maintaining a tight fit against the pipe wall. The auxiliary tool is moved through the pipe without slipping while forcing out air, and is discharged through a discharge side thereof. Air does not accumulate in the curved and bent parts of the pipe, thereby completely filling the pipe with the fluid.
