摘要： PROBLEM TO BE SOLVED: To provide a foundation pile construction method which is excellent in workability and positively obtains support force even if a long pile body is employed.
SOLUTION: The foundation pile construction method is carried out by using an auger having an excavating blade, and a rotary pressing pile device 1 having an excavating blade 16 larger than the pile body 2 on a distal end 3 of the pile body 2 and pressed for excavation by axial rotation. According to the method, the ground is preliminarily excavated by the auger to form an excavated hole 61, and a foot protection liquid is injected to a lower portion of the excavated hole 61 to form a foot protection portion 62 formed of a mixture consisting of the foot protection liquid and soil, followed by drawing up the auger 51. After back filling discharged soil into the excavated hole 61, the rotary pressing pile device 1 is axially rotated to pressing the pile body 2 into the excavated hole 61. By virtue of the preliminary excavation of the auger 51, even a long pile is easily built in, and by virtue of the foot protection portion 62 formed by the auger 51, predetermined support force is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a foundation pile structure using a prefabricated concrete pile capable of maintaining a function even after a great earthquake by holding down to the damage of only a pile bottom part without breaking the whole enlarged bulb even under the action of vertical load exceeding the limit load of a pile lower end part.
SOLUTION: The lower end of the prefabricated concrete pile A integrally has a large diameter part 21 inserted into a diameter enlarged part 31 at the lower end of a prefabricated pile insertion hole 30. The large diameter part 21 is of cylindrical shape almost equal in diameter from the upper end to a pile lower end face and provided with one or more circumferentially continuous annular recessed grooves 23a of shallow bottom at a part. The inside of the annular recessed groove 23 is filled with cast-in-place concrete 32, and the groove width of the annular recessed groove 23a is sized to cause micro slip to the surface of the large diameter part and the cast-in-place concrete by vertical load smaller than the limit bearing power at the lower end of the enlarged bulb.

摘要： PROBLEM TO BE SOLVED: To provide a rotary press-driving pile device which exerts a consolidation effect to the periphery of a pile, and is excellent in excavation efficiency.
SOLUTION: A flange-shaped enlarged-base board 12 has apertures 13 formed therein which are almost in parallel with a diameter-directional segment S of a tip 3 and located on a rotating directional side. The enlarged-base board has upper blades 14 extending upward in a direction opposite to a rotating direction, at the edge 13A of the aperture 13, on the rotating directional side, and lower blades 15 extending downward in the rotating direction, at the edge 13B of the aperture 13, on a side opposite to the rotating directional side. Since the aperture 13 is almost in parallel with the diameter directional segment S and located on the rotating directional side, the upper blade 14 and the lower blade 15 are located on the rotating directional side. Therefore when the tip 3 is rotated, the upper blade 14 and the lower blade 15 press earth on the front side of a diameter location, and a pressing force generates a force to press the earth in an outer peripheral direction, to thereby improve the consolidation effect on the periphery of the pile.
