Patent number: 9518692Abstract: 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.Type: GrantFiled: November 20, 2015Date of Patent: December 13, 2016Assignee: SIIONAN GOSEI-JUSHI SEISAKUSHO K.K.Inventors: Takao Kamiyama, Makoto Ishida, Takeshi Hasegawa

Patent number: 9200742Abstract: A lateral pipe-lining method for lining a lateral pipe that intersects a main pipe. A lateral pipe-lining material has a tubular resin-absorbing material impregnated with a curable resin and has a flange formed at one end thereof. The flange is disposed on an expandable flange-pressing implement. The expandable flange-pressing implement is expanded using a heat medium that is supplied by a first fluid source and that heats the flange of the lateral pipe-lining material to bring the flange into contact with a periphery of a lateral pipe opening of the main pipe. The lateral pipe-lining material is inserted into the lateral pipe using a fluid from a second fluid source different from the first fluid source, and the curable resin impregnated in the tubular resin-absorbing material is cured to line the lateral pipe.Type: GrantFiled: April 12, 2010Date of Patent: December 1, 2015Assignee: SHONAN GOSEI-JUSHI SEISAKUSHO K.K.Inventors: Takao Kamiyama, Koji Kaneta, Kenji Fujii, Fuminori Tanaka

Publication number: 20150027577Abstract: A rehabilitation pipe is assembled inside an existing pipe using integrally formed plastic segments each comprising an inner surface plate, side and end plates. The segments are in part or all divided in the pipe-length direction to provide a variable-width segment comprising two segment halves that are moved relative to each other in the pipe-length direction to make the width of the segment in the pipe-length direction variable. A filler is injected into a space between the rehabilitation pipe and the existing pipe to provide a composite pipe. A falsework temporarily supports the rehabilitation pipe inside the existing pipe until the filler hardens. A shape-holing member is disposed circumferentially in part or all over the inner surface of the rehabilitation pipe so as to be in contact with the inner surface plate of the variable-width segment. A support member directly or indirectly supports the shape-holding member.Type: ApplicationFiled: July 22, 2014Publication date: January 29, 2015Inventors: Takao KAMIYAMA, Masaki TAKEYAMA

Patent number: 8635753Abstract: 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.Type: GrantFiled: August 31, 2011Date of Patent: January 28, 2014Assignee: Shonan Gosei-Jushi Seisakusho K.K.Inventors: Takao Kamiyama, Koji Kaneta, Kenji Fujii, Fuminori Tanaka

Publication number: 20130284298Abstract: A rehabilitating pipe segment comprises first and second segment halves linked together to provide a variable-width segment. The first segment half has an internal surface plate, a convex plate extending parallel to the internal surface plate, and a side plate extending perpendicular to the internal surface plate. The second segment half has an internal surface plate, an internal plate extending parallel to the internal surface plate and forming a concavity, and a side plate extending perpendicular to the internal surface plate. The convex plate and a braking rubber are fitted into the concavity to link the first and second segment halves together to provide the variable-width segment. When tension of a specified amount or greater acts on the variable-width segment, the first and second segment halves move relative to each other in the pipe length direction against the braking force of the braking rubber.Type: ApplicationFiled: March 20, 2013Publication date: October 31, 2013Inventors: Takao KAMIYAMA, Koji KANETA, Kenji FUJII, Katsuyori MIURA

Patent number: 8360108Abstract: An existing-pipe rehabilitation method for constructing a rehabilitation pipe inside an existing pipe to rehabilitate the existing pipe. A rehabilitation pipe is constructed inside an existing pipe by coupling segments in the circumferential direction and the lengthwise direction of the existing pipe so that the rehabilitation pipe has a constant outer diameter. A lining material impregnated with a liquid curable resin is inserted into the rehabilitation pipe thus constructed. The liquid curable resin is cured to line the internal circumferential surface of the rehabilitation pipe with the lining material so that an inner diameter of the rehabilitation pipe lined with the lining material is smaller than an inner diameter of the existing pipe.Type: GrantFiled: December 3, 2009Date of Patent: January 29, 2013Assignee: Shonan Gosei-Jushi Seisakusho K.K.Inventors: Takao Kamiyama, Koji Kaneta, Kenji Fujii

Patent number: 8360684Abstract: A linking tool links segments for a rehabilitating pipe for rehabilitating an existing pipeline. The segment is integrally formed at least from an internal surface plate that constitutes the inner circumferential surface of the rehabilitating pipe, and side plates that have an insertion hole formed thereon and are disposed on both sides of the internal surface plate so as to extend in the circumferential direction of the rehabilitating pipe. The linking tool includes a tubular linking pin that is separable into pin halves and can be inserted into the insertion hole in the side plate of a first segment with a part of the linking pin remaining outside the first segment. The linking tool further includes a separating pin that can be inserted into the linking pin to separate the linking pin into the pin halves and press them against the first segment for anchoring thereto.Type: GrantFiled: October 19, 2009Date of Patent: January 29, 2013Assignee: Shonan Gosei-Jushi Seisakusko K.K.Inventors: Takao Kamiyama, Koji Kaneta, Kenji Fujii, Katsuyori Miura
