20080251151 | Lining material and pipeline lining method - A flexible tubular lining material impregnated with a thermosetting resin is folded and bound with tape to provide a reduced width. Two steel belts are inserted into belt loops and are removably attached so as to sandwich the lining material. During pipeline lining work, first, the steel-belted lining material is inserted into a lateral pipe from the main pipe. The steel belts are then removed from the lining material so that the lining material may remain inside the pipeline. The steel belts 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. | 10-16-2008 |

Two steel belts are inserted into belt loops and are removably attached so as to sandwich the lining material. Another steel belt is fixedly attached to one end of the lining material. During pipeline lining work, first, the steel-belted lining material is inserted into a lateral pipe from the main pipe. The steel belts are then removed from the lining material so that the lining material may remain inside the pipeline. After the steel belts are extracted from the pipeline, the lining material is 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 therein. Such an arrangement allows the lining material to be easily and smoothly inserted into a pipeline even where there is a plurality of sections bent at a right angle or close to a right angle. | 08-20-2009 |
20100258244 | Lateral pipe-lining method and flange-pressing implement for lateral pipe-lining material used in the method - A lateral pipe that intersects a main pipe is lined using a lateral pipe-lining material having a tubular resin-absorbing material impregnated with a curable resin and having a flange formed at one end thereof. The flange of the lateral pipe-lining material is disposed on an expandable flange-pressing implement, and an adhesive is applied onto the flange. Hot water is fed to the flange-pressing implement to expand and press the flange against the periphery of the lateral pipe opening of the main pipe. The hot water thus fed also heats and cures the adhesive on the flange to secure it to the periphery of the lateral pipe opening of the main pipe. The drainage performance of the main pipe 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. | 10-14-2010 |
20100282351 | Pipe-lining material and pipeline lining method - A flexible tubular pipe-lining material impregnated with a thermosetting resin is sandwiched by sandwiching steel belts in order to impart elasticity and rigidity thereto. A leading steel belt for leading the pipe-lining material is fixedly attached to the distal end thereof and the sandwiching steel belts. A drawing steel belt is removably attached to the leading steel belt to draw the pipe-lining material into a pipeline to be repaired. Additionally, an auxiliary steel belt is attached to the pipe-lining material to support the insertion thereof into the pipeline. The pipe-lining material can be inserted into the pipeline by the sandwiching steel belts, the drawing steel belt and the auxiliary steel belt. Such an arrangement allows the pipe-lining material to be easily and smoothly inserted into the pipeline even where there is a plurality of sections bent at a right angle or close to a right angle. | 11-11-2010 |
20110186205 | Lateral pipe lining material, lateral pipe lining material production method, and lateral pipe lining method - A lateral pipe lining material is inserted into a lateral pipe that intersects with a main pipe. The lateral pipe lining material includes a flexible tubular resin-absorbing material impregnated with an uncured liquid curable resin and a flange member joined thereto. The flange member comprises a flange part having an arcuately curved surface whose curvature corresponds to an inner surface of the main pipe, and a cylindrical part that extends from the flange part. The tubular resin-absorbing material has one end folded back outwards. The folded-back end of the tubular resin-absorbing material is fitted onto the cylindrical part of the flange member and pressed out over the flange part of the flange member. An adhesive is applied to the flange part of the flange member and the folded-back end of the tubular resin-absorbing material 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. | 08-04-2011 |
20120060346 | Lateral pipe lining method and lateral pipe lining apparatus - A lateral pipe lining material having a flange on one end thereof is installed on a head collar which is hermetically mounted on a pressure bag that stores the lateral pipe lining material. The head collar comprises a curved section and a cylindrical section projecting from the curved section. An expandable member is mounted to the outer circumferential surface of the cylindrical section of the head collar, and expanded so that the outer circumferential surface of the expanding member comes into close contact with the inner circumferential surface near the flange, and the inner circumferential surface thereof comes into close contact with the outer circumferential surface of the cylindrical section of the head collar. This allows a hermetical connection between the lateral pipe lining material and the head collar and ensures a reliable eversion and insertion of the lining material into a lateral pipe. | 03-15-2012 |
20120103514 | Lateral pipe lining method and lateral pipe lining apparatus - A main pipe is lined by a main pipe lining material comprising a resin pipe made of a thermoplastic resin. A flange of a lateral pipe lining material is formed of a material capable of being welded to the thermoplastic resin of the resin pipe of the main pipe lining material. The thermoplastic resins of the flange of the lateral pipe lining material and the resin pipe are heated for plastic welding by a heater to integrally join the flange of the lateral pipe lining material with the main pipe lining material. This prevents the ingress of underground water together with sediment into the main pipe from the section where the lateral pipe and the main pipe intersect. | 05-03-2012 |
