Trenchless Technologies

The course covers the use of trenchless technologies, which is a versatile installation method for small infrastructure (gas, water, sewers, etc.). It is meant as an addition to other specialist courses and the topics studied here can also be applied in other courses. Next to the installation process and the design of the linings, the organisation of a TT project will be discussed.

The course will cover aspects of:

• Cables and ducts

• Geology and geotechnics in relation to boring techniques and bore fluids

• The technique of Horizontal Directional Drilling (HDD)

• The technique of Micro-tunnelling (MT)

• Boring equipment

• Measuring en steering equipment

• Technical calculations for HDD and Micro-tunnelling

• Technical calculations for stresses in pipelines

• Renovation of existing pipelines

• Research on trenchless technologies and innovative applications

• Role of the contractor and engineering office

• Influence of contract types on project execution

• Risks and risk management

• Case discussions
