    • PROBLEM TO BE SOLVED: To provide a load bearing anchor in all directions for hanging structure on a slope face capable of adequately and uniformly receiving a soil pressure from surroundings and stably corresponding to a pulling power from multiple directions.
      SOLUTION: In an anchor hanging a non-self-standing structure on a slope face by ropes, the anchor uses a pipe anchor having a propulsion receiving part inside a tip part of the body, has a bit head on the tip, inserts an excavation assembly, in which a bit and hammer part provided with a collar part allowed to abut on the propulsion receiving part in the rear and a rotary shaft part are serially arranged, in the pipe anchor. While rotating the bit via the rotating shaft part and the hammer part, the pipe anchor is propelled to the described depth by transmitting the propulsion at the hammer part through the collar part to the propulsion receiving part. And then, the anchor is embedded in a right angle for the object to be installed on the slope face in the directions of 360 degree by extracting the excavation assembly from the pipe anchor.

    • PROBLEM TO BE SOLVED: To provide a digging head having excellent digging efficiency and less damaging a digging claw, a drilling device, a press-in machine, and a drilling method.
      SOLUTION: This digging head 30 comprises an outer peripheral head 31 and a center head 32 installed at the center of the outer periphery head 31. The outer periphery head 31 and the center head 32 are rotatable and vertically movable independently of each other. By rotating the center head 32 at a higher speed than that of the outer periphery head 31, and controlling the peripheral speed of the digging claw 33 of the center head 32 to approximately the same as that of the digging claw 33 of the outer periphery head 31, the digging efficiency can be increased. When the center head 32 and the periphery head 31 are rotated in directions reverse to each other, the directional deviation of a drilled hole 3 can also be reduced. In addition, by digging the outer peripheral part of a guide hole 4 after the guide hole is drilled by the center head 32, run-out is reduced, accuracy in the drilling direction is increased, and damage to the digging claw 33 can be reduced.

    • 要解决的问题:提供一种具有优异的挖掘效率和较少破坏挖爪的钻头,钻孔装置,压入机和钻孔方法。 解决方案:该挖掘头30包括安装在外周头部31的中心的外周头部31和中心头32.外周头部31和中心头部32可相互独立地旋转和垂直移动 。 通过以比外周头31高的速度旋转中心头32,并且将中心头32的挖掘爪33的圆周速度控制为与外周头部的挖掘爪33大致相同的圆周速度 31,可以提高挖掘效率。 当中心头部32和周边头部31沿相反方向旋转时,钻孔3的方向偏差也可以减小。 此外,通过在由中心头32钻出引导孔之后挖掘引导孔4的外周部分,减少了跳动,从而提高了钻孔方向的精度,并且可以减少挖掘爪33的损坏 。 版权所有(C)2006,JPO&NCIPI
