STEEL PIPE SHEET PILE FOUNDATION METHOD
PROBLEM TO BE SOLVED: To provide a steel pipe sheet pile foundation method that enables steel pipes to be connected together efficiently and quickly, without being affected by a connecting technique between the upper and lower steel pipes.SOLUTION: A steel pipe sheet pile foundation method is configured as follows: steel pipe sheet pile main pipes are installed together in a connected state which are built up while fitting a sheet pile joint j of the steel pipe sheet pile main pipe installed later into a sheet pile joint j of the steel pipe sheet pile main pipe precedently installed in the ground; two or more steel pipe sheet pile main pipes are continuously arranged to become an annual configuration sequentially; and finally, a closing steel pipe sheet pile main pipe P2 is installed and an annular closed steel pipe sheet pile foundation profile is formed. The closing steel pipe sheet pile main pipe P2 is constituted of two or more steel pipes 2 continuously arranged longitudinally, and is sequentially installed by a method to be built up while connecting a lower end of a next steel pipe 2 into an upper end of a precedently-built steel pipe 2. The upper end of the lower steel pipe 2 of the steel pipes 2 connected vertically is previously reinforced in a state of being hard to be deformed in a radial direction more than the other portion.
【課題】上下の鋼管どうしの連結手法に左右されず、鋼管どうしを迅速に効率よく連結できるようにする。【解決手段】先行して地盤に設置した鋼管矢板本管の矢板継手ｊに、後から設置する鋼管矢板本管の矢板継手ｊを嵌め合わせながら建て込んで鋼管矢板本管どうしを連結状態に設置し、順次、複数の鋼管矢板本管を環状配置となるように連設し、最後に閉合用の鋼管矢板本管Ｐ２を設置することで環状に閉合させた鋼管矢板基礎外郭を形成する鋼管矢板基礎工法であって、閉合用の鋼管矢板本管Ｐ２は、縦に連設する複数の鋼管２で構成すると共に、先行して建て込まれた鋼管２の上端部に、次の鋼管２の下端部を連結しながら、順次、建て込む方法で設置し、上下に連結される鋼管２の内の下方の鋼管２は、予め、上端部を他の部分より径方向に変形し難い状態に補強しておく。【選択図】図２
