To improve the cutting and mixing effect of the soil in the central area, a larger fishtail knife (horn knife) can be designed in the central area, generally about 600 mm ahead of the fishtail knife.
As the shield machine advances, the cutter rotates with the cutter head, generating axial (along the tunnel's advance direction) shear forces and radial (tangential to the cutter head's rotation) cutting forces on the excavated soil.
As the shield machine advances, the cutter rotates with the cutter head, generating axial (along the tunnel's forward direction) shear force and radial (tangential direction of cutter head rotation) cutting force on the excavated soil. Under the rotation of the cutter head, the blades and cutter heads insert into the stratum, continuously cutting away the soil ahead of the excavation face.
