Construction method for steel sheet pile walls and steel sheet pile walls

Abstract

By using connecting members that are easy to drive and extract using construction machinery, it becomes easier to reuse the connecting members together with the steel sheet piles. [Solution] A method for constructing a steel sheet pile wall is provided, using a connecting member having a flat plate-shaped gripping portion and first and second joint portions formed at the ends of the gripping portion in its cross-sectional shape, wherein at the corner of the steel sheet pile wall, the connecting member connects steel sheet piles that, in their planar arrangement, form an angle exceeding the fitting angle of the joints of the steel sheet piles.
