ABSTRACT:
Tunnel boring machine for reaming of a pilot tunnel (11). The machine housing (12) is provided with a projecting part in front of the boring head (13), said projecting part comprising a part (20) being fixed relative to the machine housing and a shield (19) being separable from the fixed part.
This arrangement permits substantially uninterrupted excavation of the tunnel and prevents the excavated soil from becoming wedged between the boring head and the tunnel front.
