COMPOSITE STEEL SHEET PILE UNDERGROUND CONTINUOUS WALL AND DECOMPOSITION METHOD OF COMPOSITE STEEL SHEET PILE

摘要

In this decomposition method of a composite steel sheet pile comprising a steel sheet pile and steel H beam which are bonded those welds that are formed by fillet welding are cut so as to leave a portion closer to the steel sheet pile than the throat when seen in a cross section perpendicular to the longitudinal direction. Thereby the composite steel sheet pile is decomposed into the steel sheet pile and the steel H beam.
