摘要

PROBLEM TO BE SOLVED: To provide a pier, a pier constitutive body constituting the pier, and a construction method of the pier dispensing with timbering work at sea, facilitating transportation and construction work, shortening a construction period, low in manufacturing and construction cost and having high rigidity and earthquake resistance and furthermore high durability.;SOLUTION: This pier structure unit 2 is composed of a slab unit 60 arranged in an internal area 80 formed by at least four steel pipe piles 4 arranged in square shape, and composed of an approximately square hard support plate part 5 and a reinforcement constitutive body 12 comprising a plurality of reinforcement groups; and a hard covering member beam unit 70 including each beam member 90 arranged between two steel pipe piles 81 adjacent to each other, and covering the beam member 90. One edge part 51 of the hard support plate part 5 of the slab unit 60 and a longitudinal edge part 52 of the beam unit 70 are joined to each other in parallel along the arranged direction of the two steel pipe piles 4 adjacent to each other.;COPYRIGHT: (C)2010,JPO&INPIT
