REQUEST FOR ADVICE on finding a solution to a major recurring problem of silt laden heavy water inflows from cutterhead in a Himalayan TBM bored tunnel. The machine is old but robust. It is an open, hard rock Jarva MK27, Atlas Copco, manufactured way back in 1991.
The problem leads to break in tunnel excavation for days in the absence of expedient means to clear the cutterhead area of the discharge water and deposited silt. Please write directly to: email@example.com
