Replacement by Trenchless Method
This module deals with the trenchless replacement of gas, water, wastewater pipelines by means of the pipe extraction method. The pipe extraction methods with split cone, pull hose, auxiliary pipe, and based on the split and cut method are presented.
LEARNING OUTCOMES
- Areas and limitations of use
- Advantages and disadvantages of this replacement method.

This module is devoted to the pipe bursting as a special method of the replacement of pipelines. In addition, the module looks at the material and equipment requirements and the effects that pipe bursting has on the pipeline itself as well as its surrounding environment.
LEARNING OUTCOMES
- Describe the various pipe bursting processes,
- Identify the effects of pipe bursting on the surrounding environment, and
- Calculate the required minimum distances to the adjacent utilities and structures.

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.

Replacement of supply and disposal pipelines (gas, water, wastewater) means the construction of new pipelines in the same alignment, whereby the new installations incorporate the function of the original pipeline.
This module covers the pipe bursting replacement technique associated with the trenchless construction method.
LEARNING OUTCOMES
- Rules and regulations;
- Pipe bursting methods, their areas and limits of application and their advantages and disadvantages;
- Selection of suitable pipe bursting methods depending on pipe defects and boundary conditions.
