COMBINED STEEL SHEET PILE, STEEL SHEET PILE WALL AND CONSTRUCTION METHOD OF COMBINED STEEL SHEET PILE
PROBLEM TO BE SOLVED: To construct a combined steel sheet pile which is excellent in desired bending rigidity, satisfies a wall thickness limit, and is excellent in economy and processability, and a construction method of the steel sheet pile.SOLUTION: There is provided a combined steel sheet pile 1 having: a steel sheet pile 2 which has a center flange part 5 located at a center in a width direction, joint parts 8 located at both sides in the width direction, and web parts 7 interposed between the center flange part 5 and the joint parts 8, and in which a crest-shaped region C is formed of a virtual line for connecting the pair of joint parts 8 at a cross section shape, the center flange part 5 and the pair of web parts 7 at both sides of the center flange part; a first steel material 3 which is joined to a face of the center flange part 5 at the crest-shaped region C side; and a second steel material 4 which is joined to a face at a side opposite to the crest-shaped region C of the center flange part 5. The center of gravity G at the cross section shape at which the steel sheet pile 2, the first steel material 3 and the second steel material 4 are combined with one another is located in a cross section of the first steel material 3.
【課題】所望の曲げ剛性、壁厚制限を満足する経済的かつ施工性に優れた組み合わせ鋼矢板および該組み合わせ鋼矢板の施工方法を構築する。【解決手段】幅方向中央に位置する中央フランジ部５、幅方向両端に位置する継手部８、および中央フランジ部５と継手部８との間に介在するウェブ部７を有し、断面形状において１対の継手部８を結ぶ仮想線と、中央フランジ部５と、その両側の１対のウェブ部７とによって山形領域Ｃが形成される鋼矢板２と、中央フランジ部５の山形領域Ｃ側の面に接合される第１の鋼材３と、中央フランジ部５の山形領域Ｃとは反対側の面に接合される第２の鋼材４とを備え、鋼矢板２、第１の鋼材３および第２の鋼材４を合わせた断面形状における重心Ｇが第１の鋼材３の断面内に位置する、組み合わせ鋼矢板１が提供される。【選択図】図１
