Claims

[Scope of utility model registration request]

A plurality of cutter drums that are rotated around at least one pair of horizontal shafts by a drive motor, a teeth drum that holds a plurality of drilling teeth and tooth holders attached to the outer periphery of the cutter drum, and a plurality of cutting teeth that are cut by the drilling teeth. An underground wall excavation system that is equipped with an earth removal means for discharging earth and sand, a support frame that supports these together, a base machine that lifts and lowers the support frame, and a power unit that supplies power such as hydraulic pressure to operate these. An underground wall excavation device, characterized in that the teeth drum is attached to a cutter drum via a buffer member.
