COMBINED STEEL SHEET PILE, STEEL SHEET PILE WALL AND CONSTRUCTION METHOD OF COMBINED STEEL SHEET PILE

摘要

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.;COPYRIGHT: (C)2015,JPO&INPIT
