TERRATEC has announced a TBM order to India for the Municipal Corporation of Greater Mumbai’s (MCGM) Amar Mahal II Tunnel Project (AMT-II), in Maharashtra. Patel Engineering Limited has selected TERRATEC to provide a 3.2m diameter hard rock open gripper TBM to complete two drives for its 5,531m long water transfer tunnel contract.
The AMT-II tunnel is one of a number of projects currently being undertaken by MCGM to augment and improve its water distribution system in order to meet increased demand and ensure reliable supply. The 5.5km tunnel will run from the Trombay High Level Reservoir to Hedgewar Udyan (Ghatkopar), via the Trombay Low Level Reservoir, at an average depth of 80 to 90m.
In order to work effectively in the mixed Basalt expected along the project alignment, the tough yet versatile TERRATEC open gripper TBM will be equipped with 22 heavy-duty 15” back-loading disc cutters, as well as anti-wear plates and lubrication systems to assist with wear prevention and dust suppression.
In addition, the machine will be fitted with a custom made probe drilling system for probing and grouting of the ground ahead of the TBM; as well as rock bolters, a steel arch erector and shotcrete pump to assist in ground support activities as the TBM progresses along the alignment.
The order comes following the very strong performance of numerous TERRATEC TBMs that have been used in India in recent years.
