SHEETING PILE Russian patent published in 2019 - IPC E02D5/02 

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. Sheeting pile of closed tubular section contains open U-shaped profiles welded together, and hook-like locking elements for connection of piles to sheet pile bulkhead. Pile is made of two identical open U-shaped profiles, each of which on the end of one of two side shelves is made with hook-like locking element so that in welded to each other profiles, hook-shaped elements are directed to different sides: at one profile – by hook up, and at other one – by hook down, at that side flanges of profiles without locking elements are welded with side flanges having locking elements.

EFFECT: reduced cost of construction when using piles of the proposed structure due to reduction of metal consumption and prime cost of making piles.
