Abstract

The invention discloses a tunneling machine for pi-shaped tunnels. A first speed reducer, a second speed reducer, a third speed reducer, a fourth speed reducer, a fifth speed reducer, a six speed reducer and a seventh speed reducer drive seven drill bits to rotate through drill rods at rear ends of the seven speed reducers respectively, and the seven drill bits rotate to cut soil at the rear ends of the drill bits. Six rotating shafts rotate to drive two connection arms on each rotating shaft, then rotating arms are driven to rotate around the rotating shafts, the rotating arms rotate to cut soil in parts, with diameters smaller than those of the drill bits, between each two drill bits, and the cut soil is conveyed into a conveying device which conveys the soil outside the tunnels. The tunneling machine for the pi-shaped tunnels propels to form the pi-shaped tunnels.
