SHEET U-SHAPED COLD-BENT PILE Russian patent published in 2024 - IPC E02D5/04 

FIELD: construction; hydraulic structures.

SUBSTANCE: invention relates to hydraulic engineering and civil construction and can be used in sea and river construction of port facilities, construction of embankments and berths, retaining walls during bank protection works, as well as during road construction, construction of tunnels and foundations in cramped conditions. Sheet U-shaped cold-bent pile from a metal strip includes a symmetrical trough-shaped body consisting of a bottom with two side inclined walls with bends at the end parts, to which hook-shaped locking elements are connected, which together form the base of the pile. Side walls of the pile body are located at angles β with respect to the bottom and the base corresponding to the condition: arccos (S/0.3*H) > β > arccos (S/h), wherein the pile body height H is 23-33 of the pile thickness, the pile locking element height h is 3.6-5.0 of the pile thickness, the pile body width Wt is 45-65 of the pile thickness, and the full width of the pile Ws is 60-80 of the pile thickness piles, where: S is pile body thickness, mm; H is pile body height, mm; h is the height of the locking element, mm; Wt is the width of the pile body, and Ws is the full width of the pile with locking elements, mm.

EFFECT: increasing the load capacity of the pile and sheet pile wall as a whole at low metal consumption, reducing the installation costs due to reducing the number of immersions during the wall construction, increasing the stability of the pile during immersion and operation.
