Embodiment Construction
[0024] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and technical solutions.
[0025] The cutter head of the existing traditional full-face tunnel boring machine, through the rotation of the overall cutter head, makes the hob on the cutter head continuously squeeze the rock. When the ultimate shear stress and tensile stress exceed the shear and tensile stress of the rock itself When the strength is high, shear and tensile cracks appear, and the rock is broken by further extrusion. Due to the direct contact with the rock, the wear of the cutter is serious, and the life of the cutter head is affected.
[0026] as attached figure 1 As shown, the cutterhead layout form adopted in the present invention is a cutterhead in the form of two synchronously rotating cross-shaped spokes with identical structures: the first cutterhead 1 and the second cutterhead 2, and the centers of the two cutt...
