The TBM which has already started working in the Asian side is about 25 m beneath the seabed with daily progress of 8-10 m. The TBM is the second in the world among machines that use bentonite slurry with its 11 bar pressure, and sixth with its 13.7 m excavation diameter. Click tr/30 and here for tunnelbuilder archive.
