Continuous excavation is possible because the tunnel is circulated in the axial direction of the tunnel, and the thrust force exerted by the crawler on the tunnel excavation surface is used to generate a propulsive reaction force. Furthermore, since the formwork or support for the crawler lining immediately after the excavation equipment is used as a stand, it is possible to approach the face and perform continuous lining. Furthermore, since the crawler propels the lining material while applying a pressing force, it is possible to construct a dense lining portion that is in close contact with the mountain range.
