Geocomposite Tunnel Invert Drainage – Online technical presentation

Webinar

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

Online

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 ...

Hobsons Bay main Yarra crossing duplication project

Melbourne Engineers Australia office

The Hobsons Bay Main Sewer (HBMS), constructed in the 1960s, transfers approximately 30 per cent of Melbourne’s wastewater to the Western Treatment Plan at Werribee. 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 ...

ITA Lecture – Practical Aspects of Segmental Tunnel Lining Design

Webinar - Online only

Topic: Practical Aspects of Segmental Tunnel Lining Design After several decades of continuous progress, mechanized tunnelling has now become the main method applied in almost all types of geology, all sizes, and in increasingly shorter lengths. The predominant excavation support system for TBM tunnels consists of a one-pass precast concrete segmental liner which in addition ...
