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

摘要： PROBLEM TO BE SOLVED: To provide a pile construction method for shortening pile construction time by effectively using motive power of a driving motor for an auger excavator, and a pile head part expandably rotating device used therefor. SOLUTION: This pile construction method repeats an auger precedently excavating process for excavating the ground by lowering an auger rod by the prescribed depth while rotating the auger rod by wholly transmitting the motive power of the driving motor for the auger excavator to the auger rod without being transmitted to a pipe pile, an auger pulling-up process for pulling up a tip auger head in a pipe pile tip part by lifting the auger rod and a pile-auger rotatably intruding process for rotatably intruding both up to a depth position exceeding no depth excavated by the precedently excavating process by mutually rotating the pipe pile and the auger rod in the opposite direction by transmitting the motive power of the driving motor to both the pipe pile and the auger rod in this order.

摘要： PROBLEM TO BE SOLVED: To provide an excavating device by which a drive shaft can be moved vertically while maintaining the opened state of expansion excavation blades. SOLUTION: An extension shaft 3 is splined in the extension direction of the lower end side of a drive shaft 2, and auxiliary links 7 for rotating operation of the expansion excavation blades are interposed between the expansion excavation blades 6 on the outer periphery of the extension shaft 3 and the drive shaft 2. By rotating the extension shaft in one direction while moving it in an extending direction with respect to the drive shaft, key members are moved to the side end parts of widened parts of splines into which the key members are fitted and the extended state of the extension shaft is maintained. By rotating the drive shaft in the opposite direction, the key members are disengaged from the widened parts of the splines so that the extension shaft can relatively move in the contraction direction with respect to the drive shaft. The widths of the splines of the positions except the widened parts of the splines are formed to be larger than those of the key members. A stopper mechanism 40 is provided on the outer peripheries of the drive shaft and the extension shaft to inhibit the movement of both shafts in the extension direction when the extension shaft is at the contraction position with respect to the drive shaft and the key members are on the reverse rotation side in the splines.

摘要翻译：要解决的问题：提供一种挖掘装置，通过该挖掘装置，驱动轴可以在保持膨胀挖掘刀片的打开状态的同时垂直移动。解决方案：延伸轴3在驱动轴2的下端侧的延伸方向上花键连接，并且用于使膨胀挖掘刀片旋转操作的辅助连杆7插入在外周上的膨胀挖掘刀片6之间延伸轴3和驱动轴2.通过沿相对于驱动轴的延伸方向移动延伸轴而沿一个方向旋转，键构件移动到花键的加宽部分的侧端部分，其中安装关键部件，并延长延长轴的延伸状态。通过沿相反方向旋转驱动轴，键构件与花键的加宽部分脱离，使得延伸轴相对于驱动轴在收缩方向上相对移动。除了花键的加宽部分之外的位置的花键的宽度形成为大于键构件的宽度。当延伸轴相对于驱动轴处于收缩位置并且关键构件处于开启状态时，在驱动轴和延伸轴的外周上设置有止动机构40，以阻止两个轴在延伸方向上的移动花键中的反向旋转侧。版权所有（C）2010，JPO＆INPIT
