Feb 16, 2011 (Image: Phoenix process [FI-Phoenb] - Structure of the liner hose) The Phoenix process comes from Japan where it was originally developed as an earthquake-resistant lining for gas piping. In a further developed form that has been adapted to European standards, it is used in the Federal Republic of Germany for, among others, the rehabilitation of gravity sewers of all pipe materials with circular cross section DN 150 to DN 1000 or the equivalent ovoid … |

Feb 16, 2011 The patented Inpipe process [FI-Inpip] has been in use in Germany since 1989 in the nominal size range DN 150 to DN 300 (in other countries up to DN 400) with section of the sewer lengths up to 100 m [FI-Teerb]. It is featured by a seamless, multi-layer hose that is manufactured in a special process of endless glass fibres and, for increasing the ring strength, is designed to have on its inner side, one or several glass fibre mats. The inner and outer … |

After completing the pulling, both ends are provided at the manholes with sealing packers. These packers possess removable flaps for insertion of the light train as well as for the insertion of the supply cable and the winch cable already fitted at the works (Bild 5.3.2.4.1.2.2). After insertion and connecting the light train to the winch cable and power … |

After completing the light hardening, the PE/PA internal foil is removed. The necessary completion work and testing is identical to the Insituform process (Abschnitt 5.3.2.4.1.1.1.4). The Softlining and the Berolina Liner processes are very similar to the T-Liner process and the two processes are identical. After pulling-in, the ends are closed with packers, expanded by compressed air and pressed against the inner wall of the sewer. After completion … |

Nov 23, 2004 (Image: Structure of a T-Liner) The T-Liner process is utilised independently of piping material for circular cross sections in the nominal size range DN 150 to DN 850 and sewer lengths, depending on nominal size, up to 180 m. The lining of equivalent ovoid cross sections is possible. The carrier material is a prepared hose of overlapping and displaced courses of glass and, if required, synthetic fibres, that are bordered by inner and outer protective … |

Nov 23, 2004 The Paltem S-Z Process [FI-Subte] [FI-Ashimb] and the Multiliner [FI-Rocas] work on the same principle. In both cases the multi-layer hose, produced by overlapping and soaked with resin, are expanded with compressed air and hardened by the introduction of steam at approx. 70° C or 110° C. According to information from the manufacturer, the Paltem S-Z process can presently be utilized in sewers with ovoid and circular cross sections in the nominal … |

The Insituform-KAS process corresponds in principle with the Insituform process mentioned above. An entry manhole or a correspondingly large space in the building is always required for the inversion of the UP or EP resin soaked prefabricated liner hose of needle felt. To save space, an enclosed cylindrical pressure vessel or a pressure hose is used in the place of the inversion scaffold. The impregnated liner is kept in this vessel or hose and from … |

(Image: Remote controlled lateral rehabilitation with the Insituform process (FAS) [FI-Insit] [Dilg98]) The Insituform FAS process is based on a further development of the top hat profile technique and can, among others, also be carried out directly from the sewer. In this case, an installation module is coupled to a pressure hose and in this a UP resin soaked liner hose pulled into a supporting hose is situated. A plastics form piece (flange) is fitted … |

In the KM-Houseliner process, the liner hose consists of an approx. 3 mm thick glass fibre knitted hose that is soaked by a mobile roller apparatus in-situ with a cold hardening epoxy resin specially developed for adhesion on a moist pipe (Bild 5.3.2.4.1.3.3) (Bild 5.3.2.4.1.3.3) (Bild 5.3.2.4.1.3.3) (Bild 5.3.2.4.1.3.3) (Bild 5.3.2.4.1.3.3) (Bild 5.3.2.4.1.3.3) (Bild 5.3.2.4.1.3.3).

The Brawoliner process is based on a carrier hose of 100 % polyester impregnated with cold-hardening epoxy resin and an integrated foil hose that is originally on the outside. According to the manufacturer's information , it was developed especially for the fold-free lining of laterals of DN 100 to 200 with small bend radii and bends up to 90°. The installation of the liner hose is carried out in the inversion process with compressed air (Bild 5.3.2.4.1.3.4) |

In the INFlex system [FI-UVRel], the 2-component EP resin soaked liner hose is wound in a pressure chamber and is inverted through an entry manhole with the aid of compressed air into the lateral to be rehabilitated. There are two variants as regards the hardening of the resin: either cold hardening or using UV lamps. Depending on the variation used, the nominal size range is DN 50 to DN 250 and can be used to length up to 40 m. The wall thickness … |

Nov 23, 2004 In principle, the above-mentioned cured-in-place processes can also be used for lining laterals. For practical and economical purposes, the hoses used for this purpose are usually soaked with cold hardening systems whose hardening takes place at ambient temperatures or with heat hardening systems. UP as well as EP resins are utilised for this purpose. Epoxy resins are specially preferred where odours must be prevented and gluing of the hose to the … |

Nov 23, 2004 ATV-M 143E Part 3 [ATVM143-3] defines the cured-in-place process as follows: "A hose of carrier material that can be coated with foil is soaked with reaction resin and inverted into the sewer through a manhole by means or water or compressed air or is pulled into the sewer with the aid of a winch. The hardening is carried out at normal temperature, by the application of heat or UV light with the application of internal pressure. A sleeveless liner … |

Nov 23, 2004 (Image: Sequence of the renovation of sewers by means of lining with site manufactured and hardened pipes - Grouted-in-place lining process) After TV inspection and measurement or calibration of the section of the sewer to be rehabilitated (Bild 5.3.2.4.2.2), the fabrication dimensions are determined for the HD-PE hoses to be installed (stud, preliner control hose). The HD-PE courses are then cut to the respective length and the required circumferential … |

Nov 23, 2004 (Image: Working steps in the grouted-in-place lining process - Pulling-in the hoses) Depending on the selected system, as mentioned earlier, one or more of the hoses wound on drums are pulled via the entry manhole into the section of the sewer to be rehabilitated. After reaching the target manhole, the hoses are closed off at both ends with sealing balloons (Bild 5.3.2.4.2.4) (Bild 5.3.2.4.2.4) (Bild 5.3.2.4.2.4) (Bild 5.3.2.4.2.4) (Bild 5.3.2.4.2.4) |

Feb 16, 2011 Before starting the grouting of the annular space it must be sealed at the end faces at the start and target manholes (Bild 5.3.2.4.2.5). With the control and preliner hoses, this is achieved by extrusion welding the preliner with the stud hose (Bild 5.3.2.4.2.5). In the basic version, the stud hose is welded with fleece coated HD-PE sleeves at the pipe ends.

Feb 16, 2011 Various manhole connecting systems based on HD-PE materials are available for the stud hose process depending on the requirements and the system used [FI-Troli]. One possibility of leaktight connecting the HD-PE liner for sections of the sewer of vitrified clay, GRP, concrete, etc. is the installation of a 2 to 5 mm and approx. 50 cm long fleece coated HD-PE sealing course. It is soaked in epoxy resin and pressed like a "short hose based on synthetic … |
