Abstract

Segments are linked in the circumferential direction to assemble a pipe unit. A link bolt is used to link the segments of the pipe unit in the longitudinal direction to assemble a rehabilitation pipe inside an existing pipe. An elastically deformable hollow cylindrical member having a tongue is attached to the link bolt between the inner plates. The outer diameter of the cylindrical member is larger than the insertion hole of the inner plate through which the link bolt can pass. This allows the link bolt to be prevented from falling out of the segment when the link bolt moves in the longitudinal direction due to gravity. When a force is applied to the tongue from below, the cylindrical member is elastically deformed and can be removed from the link bolt.

Abstract

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.

Abstract

Prior to lining a main pipe, a marker configured as a receiver coil (33) is set at the center (12b) of a branch pipe opening or a position separated a prescribed distance (S) from said center. On an intra-pipe robot (20), a rotatable perforating blade (31) for perforating main pipe lining material (13) that is blocking the branch pipe opening and a transmission coil (40) for detecting the position of the marker are installed coaxially or separated by the prescribed distance (S). After the main pipe is lined, the perforating blade is moved in conjunction with the transmission coil in the longitudinal direction of the main pipe and in the circumferential direction of the main pipe to perforate the main pipe lining material at the position at which the electromagnetic bonding of the two coils is maximal. Since the center of rotation of the perforating blade coincides with the center of the branch pipe opening at the position at which the electromagnetic bonding of the two coils is maximal, it is possible to perforate the main pipe lining material accurately to coincide with the branch pipe opening.

Abstract

A flexible tubular lining material impregnated with a thermosetting resin is folded and bound with binding members to provide a reduced width. Two elastic and rigid strip members are inserted into loop members attached to the lining material and are removably attached so as to sandwich the lining material. During pipeline lining work, the lining material to which the strip members have been attached is first inserted into a lateral pipe from a main pipe. The strip members are then removed from the lining material so that the lining material may remain inside the pipeline. The strip members are extracted from the pipeline, and the lining material is then made to expand via application of pressure from the inside. While kept in contact with the inner peripheral surface of the pipeline, the lining material is heated in order to cure the thermosetting resin thereof.

Abstract

To repair a pipeline (1), a lining material (3) is inserted, while being turned inside out, into the pipeline (1) by causing a pressure medium to act on a pressure container. The lining material (3) is pressed to the inner peripheral surface of the pipeline (1). In this state, vapor mist (20a) is sprayed from a vapor tube (16) and water at normal temperature is sprayed from a cooling-medium tube (30). This mixes the vapor mist and the normal temperature water of the sprayed state. The mixing causes the vapor mist to be almost uniformly cooled, and the cooled vapor mist is blown to the inner surface of the lining material (3). By this, a heat-hardening resin impregnated in the lining material is heated and hardened at optimum temperature. The same effect can be obtained without providing the cooling-medium tube (30), by spraying either only vapor mist or warm water mist.

Abstract

A method and a device for reversing a pipe lining material and a conduit restoring method using the reversing device. In the device, a cylindrical pipe lining material (1) is led into first and second pressure chambers (50) and (55) and fitted to a reversing nozzle (55a) installed at the lower end of the second pressure chamber. The pipe lining material is held by a holding jack (21) in the first pressure chamber, and pulled into the second chamber by the lowering of the first pressure chamber. When the pipe lining material is fed into the pressure chamber by a prescribed length, the second pressure chamber is sealed airtight, and the pipe lining material is reversed and extracted through the reversing nozzle by a fluid pressure acting on the second pressure chamber. Then, the first pressure chamber is raised, and the pipe lining material is orderly reversed by repeating the same operation and extracted from the second pressure chamber.

Abstract

A regenerated pipe for repairing a pipeline facility and a method of repairing the pipeline facility using the regenerated pipe. In the method, the regenerated pipe is laid down by peripherally and longitudinally, to each other, segment members (1) manufactured by integrally forming inner plates forming an inner peripheral surface with outer wall plates vertically installed on the peripheral edge parts of the inner plates through a plastic. A band (30) binding a pipe unit (10) on its outer periphery is installed on the pipe unit formed by connecting the segment members to each other in the peripheral direction. Since a tightening force occurs in the band by a fastening fitting and the pipe unit is bound by the band in the fastened state, the pipe unit is hard to cause deformation against an external force, and the strength of the regenerated pipe itself can be increased.

Abstract

A segment for a rehabilitating pipe is coupled to another segment in the circumferential and longitudinal directions of a rehabilitating pipe to rehabilitate an existing pipe. The segment has on one coupling surface a protruding part and a recessed part continuous with the protruding part and on another coupling surface a recessed part and a protruding part whose shapes respectively conform to the protruding part and the recessed part of one coupling surface. The protruding part and the recessed part of one coupling surface of one segment is brought into tight surface contact with the recessed part and protruding part of another coupling surface of another segment and interfitted thereto when one and another segments are mutually coupled in the circumferential and longitudinal directions of the rehabilitating pipe.

Abstract

Segments are successively coupled in the circumferential direction and the vertical direction to provide a rehabilitating pipe that rehabilitates an exiting pipe such as a manhole extending in the vertical direction. The segments are coupled in the vertical direction by stacking segments on previously assembled segments. A gap between the existing pipe and the rehabilitating pipe is filled with a filler after completion of the assembly as a rehabilitating pipe. The filler is hardened to integrate the rehabilitating pipe with the existing pipe as a compound pipe. With such an arrangement, the rehabilitating pipe can be laid by a simple method because the segments can be stacked on previously assembled segments using the segments' own weight.

Abstract

A spacer is constituted by overlapping on a first wedge-shaped member, whose upper surface is inclined at a prescribed angle, a second wedge-shaped member, whose lower surface is inclined at the same angle. This spacer is inserted in the gap between a inner wall surface of an existing pipe and the outer periphery of a rehabilitating pipe. Latching teeth are formed in the inclined surfaces of the first and second wedge-shaped members so that, when pressing the second wedge-shaped member to move it toward the first wedge-shaped member in the insertion direction, it cannot move in the direction the reverse of the insertion direction. Upon moving the second wedge-shaped member to the respective latch positions, the overall height of the spacer is successively increased in steps at a fine pitch, thus enabling the adjustment of the position of the rehabilitating pipe with respect to the existing pipe to be performed simply.

Abstract

A rehabilitating pipe is assembled inside an existing pipe using segments to repair the existing pipe. A coupling member is inserted through a segment when it is coupled in the longitudinal direction to another segment coupled already, and the coupling member is joined to the coupling member of another segment already coupled. During joining the segment is clamped against another segment and both the segments are coupled in the longitudinal direction. Such steps are repeated to couple other segments to segments already coupled until the rehabilitating pipe is laid to a predetermined length.
