摘要： PROBLEM TO BE SOLVED: To provide a steel pipe pile for use in civil engineering and construction fields such as a foundation of a harbor structure or a bridge and a building foundation; and to provide a method for constructing the steel pipe pile.
SOLUTION: A leading end of the hollow steel pipe pile having the leading end opened is provided with tapered outer and inner peripheral surfaces 2 and 3 which are formed by gradually reducing the diameters of outer and inner peripheral surfaces toward the leading end, respectively. The leading end of the steel pipe pile is equipped with a drilling bit 6. The ratio between the length (H1) of a tapered portion 4 in the longitudinal direction of the pile and an outside diameter (D1) of the pile in a constant part, having a fixed outside diameter, of the steel pipe pile 1 is in the range of 0.3-5.5. The ratio (D2/D1) of an outside diameter D2 of the leading end of the steel pipe pile to the outside diameter (D1) of the pile in the constant part, having the fixed outside diameter, of the steel pipe pile 1 is in the range of 0.60-0.95. The steel pipe pile 1 is rotatively jacked into ground containing hard ground through a rotary pile jacking method which applies a rotational force and a push-in force to the steel pipe pile.

摘要： PROBLEM TO BE SOLVED: To provide a pile head holding device for steel pipe pile, capable of surely holding a steel pipe pile without slippage while reducing the size and weight of the device, and a construction method of steel pipe pile.
SOLUTION: Slippage between the pile head holding device 1 and the steel pipe pile P can be prevented by allowing first and second chuck blocks 7 and 8 abut on the inner circumferential surface of the steel pipe pile P and a pair of projection parts P3 and P4 to be engaged between the pair of projection parts P3 and P4. Therefore, since vertical slippage between the head pile holding device 1 and the steel pipe pile P by vibration acting during penetration of the steel pipe pile P to the group can be prevented, pile construction can be smoothly and surely carried out by surely holding the steel pipe pile P. Further, since the device is not adapted to hold the pile only by friction of the first and second chuck blocks 7 and 8 with the inner circumferential surface of the steel pipe pile P, a mechanism for pressing the blocks is dispensed with, and the device 1 can be reduced in size and weight.

摘要翻译：要解决的问题：提供一种用于钢管桩的桩头保持装置，能够在减小装置的尺寸和重量的同时可靠地保持钢管桩而不会发生滑移，并且还可以使用钢管桩的施工方法。解决方案：通过使第一和第二卡盘块7和8抵靠在钢管桩P的内周面上，可以防止桩头保持装置1和钢管桩P之间的滑动，以及一对突出部 P3和P4接合在一对突出部分P3和P4之间。因此，由于能够防止由于在将钢管桩P穿入组内的振动作用而使头桩保持装置1与钢管桩P之间的垂直滑动能够顺利地，可靠地进行桩的施工此外，由于该装置不能仅通过第一和第二卡盘块7和8与钢管桩P的内圆周表面的摩擦来保持桩，所以省去了用于压制块的机构，并且可以减小装置1的尺寸和重量。版权所有（C）2008，JPO＆INPIT
