Results for "distance between parallel tunnel tubes"
Comments
why tubes close each other so much? Normal speaking there must be at least two diameter distance between two tubes. For example if diameter of each tube is 12 meters, they must be 24 meters away from each other. Otherwise TBMs distort the working of each other. No?
