Abstract

PURPOSE: To permit the efficient excavation by revolving a conical screw body on the surface of which a spiral groove is cut and a hollow rotary body which is connected behind the screw body and charged with the muddy soil, thus reducing the soil pressure resistance.
CONSTITUTION: Behind a conical screw body 2 on the surface of which a spiral groove 21 is cut, a hollow rotary body 3 charged with muddy soil 7 is connected, and a hume pipe 6 is connected behind the rotary body 3. The hume pipe 6 is advanced by a jack, and the screw body 2 and the hollow rotary body 3 are turned by a motor 11. Further, the soil and sand which are excavated by the screw body 2 are sent behind by the spiral groove 21, and a portion is taken into the hollow rotary body 3 from a soil/sand taking-in window 31. Further, when the muddy soil 7 in the hollow rotary body 3 are hardened, the muddy soil 7 is replaced through a mud feeding pipe 4 and a mud discharge pipe 5.
