Summary:To make it possible to more smoothly connect by improving a flatness of an end face of a connection member in a steel pipe sheet pile in which a connection member is joined to an end portion in an axial direction of a steel pipe.SOLUTION: A steel pipe sheet pile with a connection member comprises: first and second steel pipes; a first connection member welded to an end portion in an axial direction of the first steel pipe and having a first protruding portion intermittently formed in a peripheral direction at an outside of a step portion whose outer diameter gradually becomes smaller toward an end portion at an opposite side to the first steel pipe; a second connection member welded to an end portion in an axial direction of the second steel pipe and having a second protruding portion intermittently formed in a peripheral direction at an inside of a step portion whose inner diameter gradually becomes larger toward an end portion at an opposite side to the second steel pipe; and joints welded to an outer peripheral face at at least one place in a peripheral direction of the first and second steel pipes. A flatness of both an end face of the first connection member opposite to the first steel pipe and an end face of the second connection member opposite to the second steel pipe are 0.5 mm or less.SELECTED DRAWING: Figure 1 【課題】鋼管の軸方向端部に連結部材を接合した鋼管矢板において、連結部材の端面の平面度を改善することによってより円滑な連結を可能にする。【解決手段】第１および第２の鋼管と、第１の鋼管の軸方向端部に溶接され、第１の鋼管とは反対側の端部に向かって外径が徐々に小さくなる段部の外側に周方向に間欠的に形成された第１の突出部を有する第１の連結部材と、第２の鋼管の軸方向端部に溶接され、第２の鋼管とは反対側の端部に向かって内径が徐々に大きくなる段部の内側に周方向に間欠的に形成された第２の突出部を有する第２の連結部材と、第１および第２の鋼管の周方向の少なくとも１ヵ所で外周面に溶接される継手とを備え、第１の連結部材の第１の鋼管とは反対側の端面、および第２の連結部材の第２の鋼管とは反対側の端面の平面度がいずれも０．５ｍｍ以下である、連結部材付き鋼管矢板が提供される。【選択図】図１
