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. | ||||||

An excavation multi-hammer(1) improved in a bit structure comprises a hammer body(100), a joint(200), a plurality of beating members(300), a plurality of bits(400), and a fixing frame(500). The joint is disposed at an upper end of the hammer body, in connection with a rotational force supply unit and an air supply unit of an excavator. The beating members are arranged at certain intervals in the hammer body, and selectively moved down by the air pressure. The bits are mounted to a bit mounting part corresponding to the respective beating members, and supplies excavating force to the ground by being beaten by the beating member. The fixing frame is fixed to the hammer body and has a guide member wholly or partially contacting with a head part of each bit. A bit assembly for the excavation multi-hammer includes the bit having upper and lower fixing projections(412a,412b), a stopper(110) engaged with the upper and the lower fixing projections, and the guide member. The fixing frame is provided to prevent the bit from being idly rotated in the bit mounting part. | ||||||
