摘要： PROBLEM TO BE SOLVED: To ensure the accurate drilling of a pile hole throughout its length by grasping the diameter of the pile hole at that depth on the ground in real time, in consideration of the length of the drilling arm 20, by measuring the angle of the oscillation of the drilling arm 20.
SOLUTION: A drilling head 30 is constituted by oscillatably mounting the drilling arms 20 and 20 with first sensors 27 and 28 on the horizontal shaft 19 of a head body 1 with second sensors 27A and 28A along an oscillation locus. When a drilling rod 40 is normally rotated, a pile-hole axis section 42 with a diameter D
1 is drilled by means of a drilling blade 25 (a: a small-diameter drilling state). When the drilling rod 40 is reversely rotated, a base-enlarged foot protection portion 43 with a diameter D
2 is drilled (b: a large-diameter drilling state). In this case, the first sensor 27 is located in the position 27Ab of the second sensor 27A during the small-diameter drilling, and located in the position 27Ab of the second sensor 27A during the large-diameter drilling. Thus, oscillation angle data are transmitted onto the ground. When the drilling rod 40 is not rotated, the first sensor 27 is located in the position 27Aa of the second sensor 27A, and data with no drilling angle are transmitted.

摘要： PROBLEM TO BE SOLVED: To provide an expanding blade diametrically expanded state confirming method capable of easily and surely grasping the diametrically expanded state of an expanding blade in the ground without separately requiring a special device and a facility.
SOLUTION: An excavation head 1 has a hollow driving shaft 2 and an excavation shaft 3 relatively movably stored in the axial direction inside its shaft, and the expanding blade 4 is expanded and contracted by these relative movements. Resistance is reduced by forming a space 21 between upper-lower pipe ducts 22 and 23 for injecting cement milk in (a) to (c). When the expanding blade 4 starts to diametrically expand by reverse rotation as (d), the space 21 is eliminated by the contraction of the excavation head 1, and the resistance increases since the upper-lower pipe ducts 22 and 23 are dislocated. When normally rotating as (e) after the expansion, the upper-lower pipe ducts 22 and 23 are aligned, and the resistance is reduced. The diametrically expanding state of the expanding blade 4 can be confirmed by an increase/decrease in the pressure of such cement milk or the like.

摘要翻译：要解决的问题：提供一种扩展刀片直径膨胀状态确认方法，其能够容易且可靠地掌握在地面上的扩张刀片的直径膨胀状态，而不需要专门的装置和设备。解决方案：挖掘头1具有中空驱动轴2和挖掘轴3，挖掘轴3在其轴内沿轴向相对可移动地存储，并且膨胀叶片4通过这些相对运动而膨胀和收缩。在（a）至（c）中，在上下管道22和23之间形成用于注入水泥浆的空间21来减小阻力。当膨胀叶片4（d）通过反向旋转开始径向膨胀时，通过挖掘头1的收缩来消除空间21，并且由于上下管道22和23脱位，阻力增加。当膨胀后（e）正常旋转时，上下管道22和23对准，电阻减小。膨胀叶片4的直径膨胀状态可以通过这种水泥浆等的压力的上升/下降来确认。版权所有（C）2008，JPO＆INPIT
