Geocomposite Tunnel Invert Drainage – Online technical presentation
Geocomposite Tunnel Invert Drainage – Online technical presentation
Presentation abstract: Cavidrain Invert geocomposite systems are used to form a drainage layer beneath the road pavement of tunnel floors. The use of Cavidrain Invert offers a number of advantages over more traditional methods (which use crushed stone and pipes) such as: (i) reduced excavation (as they form a much thinner layer compared to crushed […]

ITA Lecture – EPB tunnelling: environmental aspects and re-use opportunities of the conditioned muck
ITA Lecture – EPB tunnelling: environmental aspects and re-use opportunities of the conditioned muck
The rapid development of mechanised tunnelling in the last decades has increased the tunnelling community’s focus on the environmental aspects of tunnel construction. The excavation carried out by using EPB (Earth Pressure Balance) machines often requires the use of foaming agents, specific products that are added to the medium intended to be excavated, in order to […]

The sewer alignment has a single sewer crossing under the Yarra River, which has deteriorated to a point where it requires rehabilitation and/or replacement. The Hobson Bay main Yarra crossing […]
