In this project, a concept for a trenchless sewer replacement machine is investigated. Existing technologies are analyzed and the choice is made to focus on the replacement of non-reinforced sewerage systems with a large diameter. Furthermore, it is shown that most trenchless replacement methods work on similar principles. Most existing replacement methods initially remove a pipe, then, directly behind the removal object, a new pipe for replacement is pushed or pulled in from a distance. The maximal replacement lengths, as well as the capability of existing systems to replace curved and non-circular shaped sections of pipe, are limited. The trenchless concept proposed in this project can extend the limitations of existing pipe replacement systems.

Problems, parameters, and requirements are identified and set-up based on information about existing trenchless technologies and expert interviews. As a result, it has been decided to split the design concept into four modules. These modules are named after the main function they perform. Namely: Cut, Create, Clamp and Transport.
Concepts are proposed for each of the four modules. Simple calculations, simulations and small-scale experiments are used to get insight into the feasibility of the modules.
