STEEL PIPE PILE, PILE HEAD STRUCTURE, PILE TYPE CONSTRUCTION, CONSTRUCTION METHOD FOR STEEL PIPE PILE, AND CONSTRUCTION METHOD FOR PILE TYPE CONSTRUCTION
PROBLEM TO BE SOLVED: To provide a steel pipe pile, pile head structure, pile type construction, etc. whose lamellar tear breakdown-resistant performance and the like are improved for a target such as a harbor construction installed in a coastal water area.SOLUTION: A steel pipe pile 1 to which the present invention is applied is used for a pile type construction 7 installed in a coastal water area and comprises a pile body 5 erected on a water bottom ground 8 and a pile head structure 2 installed on the crown side of the pile body 5. The pile head structure 2 includes a reinforcement anchorage steel plate 3 to which a reinforcement 70 inside an upper concrete 71 supported by the pile body 5 is connected, where a steel pipe made from lamellar tear-resistant steel having a 10% or more contraction value in a plate thickness direction and a 0.010 or less mass% sulfur (S) content is used at least for a junction location at which the reinforcement anchorage steel plate 3 is welded and joined.SELECTED DRAWING: Figure 2
【課題】沿岸の水域に設けられる港湾構造物等を対象として、耐ラメラティア破壊性能等を向上させた鋼管杭、杭頭構造及び杭式構造物等を提供する。【解決手段】本発明を適用した鋼管杭１は、沿岸の水域に設けられる杭式構造物７に用いられて、水底地盤８に立設される杭本体５と、杭本体５の天端側に設けられる杭頭構造２とを備える。杭頭構造２は、杭本体５に支持される上部コンクリート７１の内部の鉄筋７０が連結される鉄筋定着用鋼板３を有し、板厚方向の絞り値を１０％以上、かつ、硫黄（Ｓ）含有量を質量％で０．０１０％以下とした耐ラメラティア鋼からなる鋼管が、少なくとも鉄筋定着用鋼板３が溶接接合される接合箇所に用いられる。【選択図】図２
