As a sub-contractor of JIM Technology (JIMT), TERRATEC has announce the delivery of a 6.24m diameter EPBM to the BES-DAIHO-OKUMURA JV for its underground works contract on the Taoyuan MRT Green Line Contract GC02, in Taiwan’s Taoyuan city for the Department of Rapid Transit Systems, Taoyuan.

The TBM was produced in the TERRATEC factory, with key components coming from Japan.

The versatile machine has been designed to work effectively in the local geology which includes sandy gravel, sandstone and mudstone, that is expected at pressures of up to 2.5 bar along the alignment. It is designed to discharge large boulders through the ribbon-type screw conveyor. As the TBM progresses, the team will install 1,200mm wide reinforced concrete lining rings, consisting of five segments plus a key. Muck cars will be used.

The Taoyuan MRT Green Line is a rapid transit line of the Taoyuan Metro which consists of 6 lines. The MRT Green Line has a total of 21 stations (10 underground stations and 11 stereoscopic stations), with a total length of 27.8km. Contract GC02 includes 4 underground stations with two drives of 5.4km of tunnels. The TBM’s initial drive is about 80m and will be excavating from Mayuan station to Da’nan station.

Taoyuan MRT Green Line is anticipated to be complete in 2025. The City government plans to connect the Taoyuan Airport Line, the MRT Green Line, the Green Line to Zhongli, the MRT Brown Line, the Sanying Extension Line to extend the Bade section, and the underground Taoyuan Railway to form a ring-shaped system. Through connecting the six lines, the City MRT system will provide a mass, fast and convenient travel service for the overall urban redevelopment.

TERRATEC has been a member of the JIMT Group since 2018, which is the company created by three Japanese industrial giants: IHI Corporation, Mitsubishi Heavy Industries and JFE Engineering Corp. to merge their TBM divisions for both Japan and Overseas projects.
