BRACE SHEET WALL Russian patent published in 2019 - IPC E02D5/08 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering and civil construction and can be used in marine and river construction of port facilities, construction of embankments and moorages, retaining walls during shore protection works, as well as in road construction, construction of tunnels and foundations in cramped conditions. Brace sheet wall comprises cold rolled U or Ω or Z-shaped piles with hook-like locking elements located on opposite edges of each of piles and connecting them to brace sheet wall. Each pile of brace sheet wall is equipped with different types of first and second hook elements so that first locking element of next pile in wall is engaged with second lock element of previous pile, and the end part and inner surfaces of the root part of the first hook-shaped locking member form a slot of annular cross-section, corresponding to the size of the cylindrical part of the second hook-like locking element with thickness S and outer diameter D2, making 1.05–1.30 of the outer diameter D1 of the cylindrical part of the first lock element, wherein distance between centers of curvature radii of cylindrical parts of locking elements, which are engaged, and is W = (0.45÷0.55)×(D1-S), cm, where D1 is outer diameter of cylindrical part of first locking element, cm; S is thickness of pile body, cm. Between outer surface of cylindrical part of first lock element and inner surfaces of root of second locking element, as well as between end of cylindrical part of second locking element and inner surface of cylindrical part of first locking element there are gaps, providing possibility of specified pile turn in sheet pile wall relative to each other.

EFFECT: technical result consists in providing reliable waterproofing brace sheet wall in locking connections sheet piles between each other when turning piles relative to each other through angle of 45°, reduction of expenses at construction of brace sheet wall.
