| PROBLEM TO BE SOLVED: To efficiently draw up a casing pipe by making a ring bit insertable/drawable without requiring a second inner bit.SOLUTION: A step part 1B is formed on the tip inner peripheral part of a cylindrical casing pipe 1 with an axis line O as a center. An inner bit 2 in which a contact part 2B capable of abutting on the step part 1B is formed is inserted into the casing pipe 1 from a rear end side in the axis line O direction, a tip 2C of the inner bit 2 is projected from a tip of the casing pipe 1, and an annular ring bit 3 is arranged around the tip 2C. An engaging protrusion 6 drawably provided on the outer periphery of the tip 2C projects and is engaged with an engaging recess 10 of the inner peripheral part of the ring bit 3, and thereby the ring bit 3 is integrally rotatable in the rotation direction of excavation around the axis line O with respect to the inner bit 2 and locked to the tip side in the axis line O direction. The engaging protrusion 6 retracts toward the inner periphery side so that the ring bit 3 can be drawn toward the tip side. | ||||||

| PURPOSE: To obtain a directional multi-blade boring head, which carries out better directional boring control, efficiently works through a variety of soil conditions, and has improved cutting performance. CONSTITUTION: Directional multi-blade boring heads 1000, 1050 are disclosed, which have first and second blades 1030, 1032 each of which defines a deflecting surface 1036, 1038 for deflecting the boring head, when the head is advanced without rotation. At least one intermediate blade 1034 extends between the deflecting surfaces in a three-blade design. In a four-blade design, a second intermediate blade 1042 extends on a side opposite the first intermediate blade 1034. The directional multi-blade boring head is particularly effective in drilling a straight bore hole through a variety of soil conditions, when the boring head is simultaneously rotated and advanced along the direction of boring. | ||||||
