Zusammenfassung:PROBLEM TO BE SOLVED: To exhaust the soil from excavation effectively through minimum alteration of the facility and arrange so that the earth and sand of a specific stratum are exhausted positively. SOLUTION: A screw blade 9 is formed at the periphery of a rotary shaft 8, and a soil exhaust casing 12 having a specified length surrounding the rotary shaft 8 is arranged as capable of elevating and sinking with respect to the rotary shaft 8. The casing 12 is installed so that its foremost opening 12c is located in a place, for example near the undersurface of an idle dig region, while the casing 12 is elevated or sunk, and an improved earth is produced by taking in part of the soil and exhausting onto the ground from the foremost opening 12c.
