Abstract

See full text

A tunnel drilling machine and a method for drilling an epitrochoidal tunnel is disclosed. The tunnel drilling machine includes a tunneling machine body, a fixed gear operatively coupled to a frontal end of the tunneling machine body along a central axis of the tunneling machine body, and a drill head having a substantially triangular periphery. The drill head includes an internal gear ring, the internal gear ring being mounted on the fixed gear, wherein the fixed gear drives the internal gear ring around the fixed gear with a gear ratio of 3:1 to form an epitrochoidal tunnel.
