Title:
HAT-TYPE STEEL SHEET PILE
Document Type and Number:
WIPO Patent Application WO/2020/045118
Kind Code:
A1
Abstract:
This HAT-type steel sheet pile is provided with: a web which, in a cross-section perpendicular to the longitudinal direction of the sheet pile, extends along the width direction from a first side in the height direction of the cross-section; a pair of flanges which extend in both directions in the width direction from both end sections of the web in the width direction, and extend toward a second side in the height direction of the cross-section, and which form a flange angle θ with the width direction; a pair of arms which, on the second side in the height direction of the cross-section, extend along the width direction from respective end sections of the pair of flanges toward both sides in the width direction; and a pair of fitting couplers formed on end sections on the opposite side of the pair of arms from the respective pair of flanges. The average length W of the upper side and the lower side of a trapezoid having the web as the upper side and the pair of flanges as the respective legs, the height h of the trapezoid, the flange angle θ, and the friction angle ratio R* of the ground into which the HAT-type steel sheet pile is driven satisfy the following equations (i) and (ii), and the total width B of the cross-section of the HAT-type steel sheet pile, the web length Bw, the height H of the cross-section, and the flange angle θ satisfy the relationship B-Bw-2H/tanθ>0.
