Z-SHAPED SHEET PILE OF HIGH MOMENT OF RESISTANCE Russian patent published in 2001 - IPC

FIELD: construction engineering. SUBSTANCE: pile has two ledges with essentially parallel external sides and inclined wall joined to two ledges; inclined wall is installed at α ≅ 75^o angle to plane parallel to external sides of ledges and limited by two essentially parallel sides between points of its joining to ledges. Novelty is that each ledge has section that increases its length and protrudes beyond imaginary plane coinciding with flat surface of wall arranged at same side as external side of respective ledge. Sheet piles are fabricated by rolling them at moment of resistance higher that 4800 cm³/m per unit of wall length and moment of resistivity about 20 (cm³/m)(kg/m²). EFFECT: improved moment of resistance per unit of wall length and moment of resistivity in rolling sheet piles. 9 cl, 2 dwg
