摘要:
A lateral pipe lining material (1, 1') is inserted into a lateral pipe (31) that intersects with a main pipe (30). The lateral pipe lining material (1, 1') includes a flexible tubular resin-absorbing material (2) impregnated with an uncured liquid curable resin and a flange member (8, 12) joined thereto. The flange member (8) comprises a flange part (8a) having an arcuately curved surface whose curvature corresponds to an inner surface of the main pipe (30), and a cylindrical part (8b) that extends from the flange part (8a). The tubular resin-absorbing material (2) has one end (2a) folded back outwards. The folded-back end (2a) of the tubular resin-absorbing material (2) is fitted onto the cylindrical part (8b) of the flange member and pressed out over the flange part (8a) of the flange member. An adhesive (9) is applied to the flange part (8a) of the flange member (8) and the folded-back end (2a) of the tubular resin-absorbing material (2) to bond the tubular resin-absorbing material to the flange member, thus producing a lateral pipe lining material in an uncomplicated manner with few members.
摘要:
A lateral pipe (31) that intersects a main pipe (30) is lined using a lateral pipe-lining material (1) having a tubular resin-absorbing material (2) impregnated with a curable resin and having a flange (3) formed at one end thereof. The flange of the lateral pipe-lining material is disposed on an expandable flange-pressing implement (70), and an adhesive (82) is applied onto the flange (3). Hot water is fed to the flange-pressing implement (70) to expand and press the flange (3) against the periphery of the lateral pipe opening of the main pipe (30). The hot water thus fed also heats and cures the adhesive (82) on the flange to secure it to the periphery of the lateral pipe opening of the main pipe (30). The drainage performance of the main pipe (30) can be improved because a gap does not form between the flange of the lateral pipe-lining material and the periphery of the lateral pipe opening of the main pipe, and neither underground water nor earth or sand flows into the main pipe.

To line an inner circumferential surface of side walls (1b, 1c) of a manhole (1), a rehabilitating sheet (3, 3A, 3') made of a sheet material resistant to water and corrosion is provided in the form of a bag having a shape corresponding to the inner circumferential surface to be lined. The rehabilitating sheet (3, 3A, 3') is inserted into the manhole (1) to be lined. Block and plate frames (9, 16) are coupled inside the bag of the rehabilitating sheet (3, 3A, 3') to support it so as to have the shape corresponding to the inner circumferential surface to be lined. A gap between the rehabilitating sheet (3, 3A, 3') and the inner circumferential surface of the side walls (1b, 1c) of the manhole is filled with a filler (13), which is then hardened to line the side walls (1b, 1c) of the manhole (1). Pairs of plate frames (16) having different diameters are coupled to each other to provide ring plates (17) having different diameters. The ring plates (17) are stacked one by one from the maximum one to support the rehabilitating sheet (3, 3A, 3') so as to have a shape of the inner circumferential surface of the inclined side wall portion (1b) of the manhole (1).

A lateral pipe lining material (1) comprises a tubular resin absorbing material (2) impregnated with a setting resin, which has a flange (3) at one end thereof and whose outer surface is coated with a highly airtight film (4). A sealing tube (5) is detachably attached to the outer circumferential surface of the tubular resin absorbing material (2). The lateral pipe lining material is introduced inside a main pipe (30) and its flange (3) is brought into tight contact with the lateral pipe opening. The lateral pipe lining material (1) including the sealing tube (5) is then everted and inserted by fluid pressure inside a lateral pipe (31) toward the ground level. After the setting resin is cured, the sealing tube (5) is removed from the lateral pipe lining material. This enables the lining of a lateral pipe to always be performed reliably, regardless of the aboveground circumstances.
摘要:
A tubular pipe lining material 1 is guided to first and second pressure chambers 50 and 55 and attached to an eversion nozzle 55a that is provided at the lower end of the second pressure chamber. The pipe lining material is held by a holding jack 21 of the first pressure chamber, and is drawn into the second pressure chamber by the lowering of the first pressure chamber. When a prescribed length of the pipe lining material has been fed into the pressure chamber, the second pressure chamber is airtightly sealed, and the pipe lining material is everted and drawn out through the eversion nozzle by the action of fluid pressure in the second pressure chamber. Thereafter, the first pressure chamber is raised, and the same operation is repeated to successively evert and draw out the pipe lining material from the second pressure chamber.
摘要:
A segment (1) is an integrally formed plastic unit comprising an inner-surface plate constituting an inner circumferential surface and lateral plates and end plates that are vertically arranged on a rim of the inner-surface plate. The segments are linked in a circumferential direction and in a pipe length direction to construct the rehabilitating pipe. A pipe unit (10) is made from segments linked in the circumferential direction. A band (30) is attached for encircling the outer circumference of the pipe unit and restraining same. A fastening force is produced on the band by a metal fastener, and the pipe unit is restrained in a fastened state by the band. Therefore, the pipe unit does not readily deform due to external forces, and the strength of the rehabilitating pipe itself can be increased.
