摘要： PURPOSE:To improve workability with moderate strength given without spoiling badly the advantage in cost as soil cement. CONSTITUTION:Cement milk and steel fibers 3 are put into soft ground 1 by pressure injection while an agitator in made to penetrate therethrough, and a grilled wall-like fiber reinforced soil cement structure 2 is formed by kneading soil particles constituting the ground, the cement milk and the steel fibers 3. Then, resistance to the groundwater pressure at the time of liquefaction of the soft ground 1 can be produced with the fiber reinforced soil cement structure 2, in which the steel fibers 3 are dispersed uniformly.

摘要： PROBLEM TO BE SOLVED: To provide a joining structure of a pile head part and its construction method, for improving workability and quality, and reducing cost. SOLUTION: In this joining structure of the pile head part for joining a pile wound with a steel pipe pile or a steel pipe to a foundation of a structure, a diametrally expansive member 5 is composed of an outer steel pipe 3 for surrounding the pile head part 3 from the periphery and a horizontal diaphragm 4 arranged on the lower end of clearance so as to block up the clearance between the outer steel pipe 3 and the pile head part 2. The diametrally expansive member 5 has a plurality of anchor reinforcements 8 embedded in a foundation beam 7 in an outer peripheral part, and is placed on a ring member 6 annularly installed in the pile head part 2. The horizontal diaphragm 4 is fixed to the pile head part 2, and a filler 9 is filled in the clearance between the outer steel pipe 3 and the pile head part 2. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a foundation pile followable to large deformation, and holding the support function of a structure in an earthquake and after the earthquake without fracture even to the large bending moment, shearing force and a turning angle thereby caused in a pile body generated in a stratum boundary and the vicinity of a pile head.
SOLUTION: This foundation pile is formed by connecting existing piles. Maximum bending yield strength is equal to or less than an existing pile general part under working axial force. A highly tough member 2 having curvature at maximum bending yield strength generating time larger than the existing pile general part is arranged in an underground part or a pile head part. For example, when using a steel pipe pile as the foundation pile 1, a steel pipe having an outer diameter smaller than the general part 1a of the foundation pile 1 is installed in the underground part or the pile head part of the foundation pile 1 as the highly tough member 2.
