摘要： PROBLEM TO BE SOLVED: To provide an excavation head of an excavator for constructing a foundation pile, superior in excavation performance, capable of securing the quality of a foot protection expanded bulb, and capable of suppressing an earth removal quantity when pulling up, in the excavator in the form of gradually diametrically expanding an expanding blade by a spline structure.
SOLUTION: This excavation head 1 has a hollow driving shaft 2 and an excavation shaft 3 relatively movably stored in the axial direction inside its shaft. The expanding blade 4 joined by a pin to the driving shaft 2 side is expanded and contracted via a diametrically expanding plate 5 on the excavation shaft 3 side by using these relative movements. A spline is formed of a U-shaped key way 6 on the inner surface side of the driving shaft 2 and a key 7 on the outside surface side of the excavation shaft 3. The key way 6 is formed in a U shape out of a guide part 6a in the vertical direction, a first locking lock part 6b in which the key 7 is engaged in the circumferential direction when normally rotating the driving shaft 2 in the diametrically contracted state of the expanding blade 4, and a second locking lock part 6c in which the key 7 is engaged in the peripheral direction when normally rotating the driving shaft the a diametrically expanding state of the expanding blade 4.

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 rotary penetration pile and the construction method by which a front end open pile is hardly clogged with earth and sand hindering the construction work, and a propulsive force generated upon rotary work becomes large.
SOLUTION: A front end of a steel pipe pile 1 is cut out and two blades 2 are fitted to its front end face 3. Each of the blades 2 has the shape that a steel disk having a substantially circular conic surface is substantially divided into two. The blades 2 are fitted symmetrically to the front end face 3 of the pile, which is cut, in a manner that they are inclined to intersect with each other when viewed from the front. An angle formed by a face orthogonal to an axis of the steel pipe pile 1 in a normal direction of the steel pipe pile 1 and a surface of the blade 2 gradually increases from an angle η
s at a starting end of the blade 2 to an angle η
e at the finishing end of the blade 2, or from the downward angle, to be horizontal or to be the upward angle.

摘要： PROBLEM TO BE SOLVED: To provide a rotational penetration pile for enhancing penetration performance into the ground, and superior in support performance and economic efficiency, by efficiently reinforcing a blade part of the pile tip.
SOLUTION: This rotational penetration pile 1 is formed by welding a blade 4 to the tip of a steel pipe 2 cut out in a spiral shape, and generates a step height between a starting end part and a tail end part of the base 4 in a tip cutout shape of the steel pipe 2. Generation of a crack from a step height part when rotatably penetrating the pile 1, is prevented by blocking up the step height part by welding a substantially triangular reinforcing plate 5 over an under surface of the tail end part from the starting end part of this blade 4. In common use, reduction in tip bearing power by the inflow of sediment from this step height part is prevented.

摘要： PROBLEM TO BE SOLVED: To provide an excavator for a buried pile, and a construction method for the buried pile requiring no consumable such as a shear pin, eliminating complicatedness such as an adjustment of locking force, and capable of changing an excavation diameter in construction. SOLUTION: Excavation and agitation-mixing of excavation sediment and a curing-filler such as cement milk are performed in a state of projecting from the lower end of a hollow pipe 2 by inserting an excavation rod 2 into the hollow pipe 1. A cylindrical expansion-contraction control member 6 is coaxially arranged in an outer peripheral part of the excavation rod 2, and these members are mutually threadedly engaged by a screw part. A rotation restricting member 7 is projected toward an inner surface of the hollow pipe 1 from an outside surface of the expansion-contraction control member 6, and the excavation rod 2 is rotated in a state of locking this rotation restricting member 7 on a receiving part 8 of the hollow pipe 1, so that the expansion-contraction member 6 moves upward or downward. The expansion-contraction control member and an excavation blade 3 are connected by a link 10, and the excavation blade 3 is expanded and contracted by the upward or downward movement of the expansion-contraction control member 6.
