打設装置。 A ring locking protrusion for locking the support ring of the thin steel plate is protruded from the lower end of the driving guide which is driven into the ground along with the thin steel plate to be driven, and the upper part of the driving guide is provided with a tensioning device that tensions the thin steel plate by locking a hook to a hanger portion at the upper end of the thin steel plate, and the thin steel plate is driven into the ground together with the driving guide. In the underground driving device for thin steel plates, an excavation drive device is mounted on the guide head at the upper end of the driving guide via a press-fitting cylinder in order to press-fit the driving guide into the ground. , a rotary shaft rotationally driven by the excavation drive device passes through the guide head, extends along the driving guide, and protrudes from the tip of the driving guide, and an auger digging blade is integrated with the tip of the rotary shaft. The outer periphery of the auger cutting blade protrudes in the outer radial direction of the auger cutting blade when the auger is rotated in the digging direction, so that the enlarged digging radius is expanded to the outside of the thin steel plate, and when the auger is rotated in the non-excavation direction, the cutting radius is reduced. An underground casting device for a thin steel plate, characterized in that an enlarged blade is supported that retreats so that its radius is inside the thin steel plate.
