AE-08 Replacement: Pulling-In the Pipe String during the Pipe Bursting Process

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.

After completing this module, you will have a sound knowledge of:

• 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.
