SHEET-PILE WALL Russian patent published in 2007 - IPC E02D5/04 E02B3/06 

FIELD: construction, namely bulkheads, piles, or other structural elements specially adapted to foundation engineering, particularly used to construct sea-front walls, berths, shore-protective and other hydraulic structures, as well as all-purpose retaining walls.

SUBSTANCE: sheet-pile wall includes vertical members having wavy profiles in plane view. Each member has cross-section, which defines flanges extending from different sides of longitudinal wall axis and in parallel to the axis so that the flanges are mutually offset along longitudinal wall axis. The flanges are connected with each other through transversal walls extending at obtuse angle to flanges so that extreme transversal wall halves are created. Each wall half has cam and yoke arranged from opposite member sides and connected to free well half edges so that cam and yoke create interlock. Each yoke is connected to inner surface of well half. Each cam is secured to inner surface thereof. Wall half area is equal to half of wall area in horizontal section of each vertical member. Ratio between flange area to wall area is within 0.9-2.1 as obtuse angle between flange and well, as well as between flange and wall half varies from 91 to 150°, in dependence of above angle magnitude.

EFFECT: decreased unit metal consumption along with load-bearing capacity retention.
