CONSTRUCTION METHOD FOR STEEL SHEET PILE-COMBINED SPREAD FOUNDATION, AND STEEL SHEET PILE-COMBINED SPREAD FOUNDATION

摘要

PROBLEM TO BE SOLVED: To improve workability of a construction method for a steel sheet pile-combined spread foundation. SOLUTION: A plurality of Z-shaped steel sheet piles 53 are driven into the ground in such a shape as to have a corrugated cross section, so as to form a rectangular-cross-section steel sheet pile structure 5. The ground 2 enclosed with the structure 5 is excavated. A perforated steel plate 7 and an anchor reinforcement 9 are welded to an inner surface of a front-side flange 53a of each pile 53. Cast-in-place concrete is placed in a space which is enclosed with the structure 5, so as to form a footing. The adoption of the pile 53 enables a mounting point of the anchor reinforcement 9 to be limited to this side (footing side). COPYRIGHT: (C)2006,JPO&NCIPI
