PURPOSE: To enable a vertical plate-shaped structure that can be constructed into a uniform thickness and has high rigidity to be constructed efficiently. CONSTITUTION: A plurality of drilling units, each having at least a cutter 10, a cutter drive 11 and a soil discharging device 12, are incorporated in parallel to one another along the vertical direction of a shield machine body 2 taking the form of a box which is elongated in the vertical direction that is perpendicular to the direction X of excavation. A shield jack 14 for propelling the shield machine or a towing means for towing the shield machine is provided, and a soil discharging device 13 which receives muck from the soil discharging device 12 of each drilling unit and discharges it to the upper side Y is installed. |
