WebTunnels are round because they're least likely to collapse. cnash • 6 yr. ago. Tunnels are round because the machines that drill them are, well, drills. They work by spinning and grinding as they spin. I suppose you could drill a tunnel, and then chip out the sides to make it square, but it would be expensive and pointless. WebWhen tunnelling with a Double Shield TBM, a rotating cutterhead equipped with disc cutters is pressed against the tunnel face with a pressure of up to 32 tonnes per disc. Due to the rolling movement of the discs, single pieces – so-called chips – are broken out of the rock. Water jets can cool the cutting tools and reduce dust formation.
