[0037] In the embodiment, during the construction process of the shield machine, the tunneling machine advances forward and fixes the pipe segment of the counterforce frame on the inner wall of the tunnel. Within the range of the fixed counterforce frame, the counterforce frame is composed of multiple groups of pipe segments. The fixed sleeve 1 is erected in the internal space. The fixed sleeve 1 has a flat bottom end structure, so that the bottom end of the fixed sleeve 1 faces downward. The internal position of the fixed sleeve 1 is controlled so that the fixed sleeve 1 is located at the center position of the tunnel.
