Replacement refers to the installation of sewers and drains in place of existing pipelines, where the new pipeline takes over the functions of the old system. The focus of this module is the trenchless replacement method by the means of pipe bursting. In addition to the process description, the areas of application and limits as well as options for quality assurance are discussed.
LEARNING OUTCOMES
- Identify and implement the most important rules and specifications,
- Select the appropriate replacement methods based on the type of damage and limiting conditions, and
- Identify possible causes of errors and describe quality assurance measures.

This module focuses on the parameters that must be considered when pulling in the pipe string for gas, water and wastewater pipelines. In addition to a basic description of the replacement procedure, the importance of tensile forces, bending radii and the dimensioning of the excavation pit is therefore the focus of attention.
LEARNING OUTCOMES
- Maximum permissible tensile forces;
- Elongations and compressions of the product pipe due to the pulling-in process;
- Determination of the minimum excavation pit length and
- Required material properties of plastic pipes.
