加圧式シールド掘進機における破砕装置。 A fixed tooth and a movable tooth are provided in a casing of a crushing device installed near a partition wall of a shield body, and a rod of a drive device installed outside the casing is connected to the movable tooth by passing through a side wall of the casing, The movable teeth are oscillated relative to the fixed teeth by the expansion and contraction movement of the rod, thereby crushing gravel in the excavated soil and discharging it into the mud drainage pipe. Between a seal case that holds a seal and has a greasing groove between the seals and the casing side wall or its overhang, one end is in close contact with the seal case and the other end is in close contact with the casing side wall or its overhang. A mud water pressurizing type, characterized in that a vibration absorber that is attached to the rod and deforms following the vertical swing of the rod is interposed, and a portion of the vibration absorber facing the face side is covered with a flexible body that can be expanded and contracted. A crushing device in a shield tunneling machine.
