U-SHAPED SHEET PILE WITH A LOW RESISTANCE OF DRIVING Russian patent published in 2002 - IPC

FIELD: U-shaped sheet pile with a low resistance of driving. SUBSTANCE: the U-shaped sheet pile has a chord that is made plane over the entire width, two plane flanges coupled to the chord forming concave angles between them, lock joint members, the depth-to-useful width ratio of this pie exceeds or equals 0.18, and its useful width is determined by the distance between the central axes of the lock joint members, and the depth is determined by the distance between the plane passing through the central axes of the two members of the lock joint and the outer surface of the chord, the concave angles of the pile have increased thicknesses. EFFECT: reduced resistance of driving at a preset cross-section of the U-shaped sheet pile due to the increased thickness of concave angles. 8 cl, 2 dwg
