たことを特徴とするシールド掘進機。 Two shield tunneling machines are made to tunnel facing each other toward a tunnel joining point, and the tips of both shield tunneling machines are mechanically connected at the joining point to join the tunnels on both sides. A hood plate is connected to the tip of the skin plate that constitutes each shield outer shell of the shield tunneling machine, a joining ring is arranged on the outside of the hood plate so as to be movable forward and backward, and is fixed to the hood plate between the joining ring and the hood plate. A shield excavator characterized in that a spacer is interposed therebetween, and tapered surfaces that fit into each other are formed at the tips of both joining rings.
