The RIB-LOC-Relining-System requires the following equipment: - 3 persons required on the site
- Winding machine with exchangeable winding forms
- Hydraulic pump for the drive
- Holder for the plastics profile pipe roller
- Light lifting equipment
- Equipment for leaktightness testing
- Equipment for annular space grouting
- Cutting, boring or milling tools for the connections (robot)

Advantages of RIB-LOC-Relining-System: - short construction time
- few traffic restrictions
- re-establishment or increase of the static load bearing capacity of the pipeline to be rehabilitated
- possibility to reduce the drainage cross section of hydraulically oversized sewers
|
|
|
| (Image: Pros and cons) |
Disadvantages of RIB-LOC-Relining-System: - extensive re-restablishment of connection sewers in the non-accessible nominal size area when using the open-cut method
- reduction of the cross section of the pipeline to be rehabilitated
- damage areas must be sealed first due to strong water infiltration
- necessity of annular space grouting with buckling risk of the liner
- wastewater deposits in the annular space lead to cavities in the …

The Japanese SPR process (Sewage Pipe Renewal Method) is characterised by the winding of a liner of PVC rib profiles with steel reinforcing strips within the section of the sewer to be rehabilitated. The PVC rib profile is wound off a roll and added via an entry manhole to a self-propelling winding machine that moves along an defined space adapted to the contour of the sewer to be lined . | | (Image: Spiral lining process RotaLoc with reference to [FI-… |

The lecture deals with the method variants and the application areas of lining with spirally-wound pipes. |
|
The lecture "Lining with prefabricated pipes without annular space (Lining with close-fit pipes)" describes the two different method variants, deformation process and reduction process, as well as their areas and limits of application. |

According to EN 752-5 [DINEN752-5:1995], renovation is understood to be measures aimed at improving the current functionality of sewage pipes and sewers under full or partial inclusion of their original substance. | |
The measures used for carrying this out are : - Coating processes and
- Lining processes .

Full linings serve the purpose of replacing or enhancing the resistance properties to physical, chemical, biochemical and/or biological attacks, for hindering the renewed formation of incrustations, for replacing and/or increasing the static bearing capacity as well as the leaktightness. | |

Lining processes are differentiated as follows - lining with pipes and
- Lining with installed individual elements (segmental lining process) in the form of
- Partial segmental lining of the invert region or the gas space and
- Full segmental lining

The lining with pipes is understood to be, similar to (not found),the creation of self-supporting full lining of sewer sections based on -
Prefabricated pipes;
-
Site manufactured pipes; and
-
Site manufactured and hardened pipes.

Lining with prefabricated pipes is characterised by the pulling, pushing or driving-in of pipes (also lining pipes) into the section of the sewer to be rehabilitated. One differentiates between: - Lining with continuous pipes
- Lining with discrete pipes

Lining with close-fit pipes - PE- or PVC-lining pipes are used in particular.
- Pulling-in a plastic continuous pipe (lining pipe), whose cross-sectional dimensions have been reduced by predeformations, into the section to be rehabilitated.
- Subsequent expansion until it clings to the interior wall of the sewer.
- Minimising the cross section reduction of the section that has to be rehabilitated compared to the lining with continuous pipes with annular …
