Abstract:
A tunnel boring machine includes: a shield body; a cutterhead assembly, a first drive mechanism; a second drive mechanism; and a third dive mechanism The cutterhead assembly includes a main cutterhead and a plurality of auxiliary cutterheads. The main cutterhead is rotatably arranged at a front side of the shield body and defines a soil chamber between the main cutterhead and the shield body, and is movable along an up-down direction. The plurality of auxiliary cutterheads are rotatably arranged in the soil chamber, and adjacent to a bottom of the shield body and arranged at left and right sides of a vertical central line of the main cutterhead. A rotation diameter of the main cutterhead is greater than a rotation diameter of the auxiliary cutterhead, and the rotation diameter of the main cutterhead is the same as a maximum width of the shield body.
