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 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： A spacer for positioning a rehabilitating pipe has an elongated shape with both end portions in a longitudinal direction cut off at an angle. The spacer has a transverse width increasing gradually from an upper surface portion to a bottom surface portion and a space formed in the bottom surface portion to correspond to a shape of the upper surface portion, thereby allowing a plurality of the spacers to be stacked on one another in the thickness direction.

摘要： An existing pipe that is to be rehabilitated has concavely curved portions and straight portions as viewed in cross-section orthogonal to the longitudinal direction of the existing pipe. For pipe rehabilitation at the curved portion of the existing pipe, a plurality of rectangular parallelepiped segments whose inner surface plate, side plates and end plates are all rectangular are used. A spacer is interposed between the end plates of the rectangular parallelepiped segments. The spacer has first and second contact surfaces that are inclined relative to each other and come into contact with the end plates of the rectangular parallelepiped segments when they are linked in the circumferential direction.

摘要： One cylindrical pipe is inserted into the hollow cylindrical portions of first and second holders made of hard plastic, and the other cylindrical pipe is inserted into the hollow semi-cylindrical portions. The first and second pipe holders are butted together at butt surfaces, respectively. The cylindrical pipe inserted into the butted hollow cylindrical portions is held in the hollow cylindrical portions using a clamping tool, and the cylindrical pipe inserted into a cylindrical portion that becomes hollow cylindrical by butting is held in the hollow semi-cylindrical portions using the clamping tool.

摘要： Segments are linked in the circumferential direction to assemble a pipe unit, which is linked to another pipe unit in the pipe-length direction to assemble a rehabilitation pipe inside an existing pipe. Before the pipe unit is assembled or after the pipe unit has been assembled, a spacer is attached to the segment using a spacer holder to prevent the spacer from falling down from the segment. The pipe unit having the spacer attached to the segment is linked to the pipe units that have already been linked. The rehabilitation pipe is positioned relative to the existing pipe using the spacer that is attached to the segment. A filler is injected between the positioned rehabilitation pipe and the existing pipe.

摘要： A plurality of segments is provided which comprises an inner surface plate, and side plates and end plates provided upright on a peripheral edge of the inner surface plate. The inner surface plate, the side plates, and the end plates are formed integrally from a plastic material. The segments are linked in a circumferential direction with a diameter expander being inserted between the adjacent segments to assemble a closed ring-shaped diameter-enlarged pipe unit. The diameter-enlarged pipe units are sequentially linked in the pipe-length direction to install a segmental rehabilitation pipe inside the existing pipe. An opening is formed in the end plate and the diameter expander so that the filler material injected into a space between the existing pipe and the segmental rehabilitation pipe flows in or out through the opening.
