Zusammenfassung:	PROBLEM TO BE SOLVED: To continuously form an excavation groove along a horizontal direction and to discharge excavated earth efficiently. SOLUTION: An excavator 1 comprises running bodies 2 and 3, a guide cell supported by the running bodies 2 and 3, an auger drive device 6 freely movable along the guide cell. Further, the excavator comprises an auger shaft 10 coupled to the auger drive device 6 and rotatable around an axis, and underground frames 11 supported by the auger drive device 6 and consisting of auger- surrounding frame K in a U-shape in a cross section to surround the three sides of the auger shaft 10, and underground frame 11 integrally formed adjacently to the auger-surrounding frame and consisting of wall surface supporting forms S.
