摘要： PROBLEM TO BE SOLVED: To increase anchoring strength to a reinforcement and concrete by using a diametrically expanded part formed by applying hot upsetting treatment to the reinforcement as an anchoring part. SOLUTION: In an anchoring part reinforcement 1A, a disk-shaped diametrically expanded part 1b is respectively formed in a reinforcement part having a constant diameter, that is, both side end parts of an ordinary part 1a as the anchoring part by hot upsetting treatment. Since this diametrically expanded part 1b can secure the large action area even if an outside dimension is reduced more than an ordinary anchoring part by bending a reinforcement end part in a U shape or an L shape, anchoring strength to the other reinforcement and concrete can be increased. Moreover, since the diametrically expanded part 1b is completely made as an integral structure in the ordinary part 1a, connecting strength of the diametrically expanded part 1b and the ordinary part 1b increases, so that the strength is stable. To increase strength and anchoring strength of a connecting part, there are cases where a reinforcing part for enlarging an outside diameter more than the ordinary part of a reinforcement is arranged in a root part of the reinforcement connected to the diametrically expanded part 1b and a locking projection is arranged in a peripheral part of a surface crossing the reinforcement axis of the diametrically expanded part 1b.

摘要： PROBLEM TO BE SOLVED: To reduce the construction quantity of SCP and reduce the construction cost of a foundation by confirming a compaction effect on a ground by a file by ground test in the soil improvement of a target ground having a possibility of liquefaction, and taking it into consideration as substitution ratio. SOLUTION: A steel pipe pile 10 is test-constructed to confirm the clocking effect of the steel pipe pile 10 in a target ground and the compaction effect on the peripheral ground by the drive of the pile 10. The substitution ratio by the drive of the pile 10 us determined from a confirmation test and existing data, and a composed substitution ratio on the target ground is calculated to determine the substitution ratio by a sand compaction pile 20. The pile diameter and the pile pitch P1 are then set. When the end of the pile 10 is opened, the SCP 20 is partially constructed to confirm the improvement effect as foundation ground. The compaction effect is evaluated, and the design as countermeasure to liquefaction and test construction of the driven pile 10 and the SCP are performed to confirm the improvement effect. The construction quantity of SPC which is a natural countermeasure to liquefaction can be surely reduced.
