Tunnel boring mashine for full face boring tunnels with a horse-shoe shaped profile

摘要

The tunnel boring machine (hereinafter: TBM) for full-profile driving of tunnels with horseshoe-shaped transverse profile is characterized by the fact that it includes rotary circular front cutting head (3) mounted on sliding shaft (2) and connected to the driving equipment, as well as of conveyer system for catching and transfer of extracted material, and of other outfit related to function of the circular front cutting head (3). The tunnelling machine also includes supporting casing (1) mounted on sliding shaft (2) with circular front cutting head (4), or the tunnelling machine jacket is used as the supporting casing (10). The supporting casing (1 ,10) is equipped with fixing system (1.1 , 10.1). The tunnelling machine also includes two finishing cutting heads (4) in mutual mirror- and symmetrical arrangement with respect to the axis (3.2) of rotation of the front cutting head, and are mounted (from the machine movement view) after the rotation front cutting head (3), and each finishing cutting head (4) has a rotation body (4.1 ) on non-rotary shaft (5.2.2). The body (4.1 ) delimits the inside area in which its driving equipment (5) is arranged, attached to the non-rotary shaft.
