Abstract
A deep level sewer installation, employing a trenchless technology method required as a result of excavations for a new freeway in Athens, is described. For the first time, pipes had to be jacked to drive sections over 200 m in length under the city. In addition to its technical merits, the method provided advantages in terms of social and environmental issues. Very little traffic disturbance was caused, together with no disruption of other services or creation of dust pollution during construction. It also did not damage the pavements of the city. This contrasts to the scars left on the roads, due to trenching. Pipe jacking, however, needs the construction of shafts along the alignment, arranged at distances determined by the cost effectiveness of the system to jack the pipes. It was decided to monitor the jacking force requirements as the pipes advanced. This response during driving was then analyzed and compared to the predictions presented by other researchers. Such measurements and analyses may allow for the formation of a database to permit the right choice of an appropriate excavation unit and the successful planning of any future similar projects.
