A concept for trenchless pipe replacement

Abstract

In this project, a concept for a trenchless sewer replacement machine is investigated. Existing
technologies are analysed and the choice is made to focus on the replacement of nonreinforced
sewerage systems with a large diameter (¸ 800mm). 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 length as well
as the capability of existing systems to replace curved and non-circular shaped sections of pipe
are limited. This is due to the fact that existing systems either push or pull a replacement pipe
from the top surface into the underground.
The approach in this project is the creation of a pipe directly behind a cutting module. The
proposed trenchless concept could extend limitations of existing pipe replacement systems.
Experts form the municipality of Rotterdam have been interviewed and a use-case has
been provided. 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.
