METHOD OF REINFORCING PIPE SHEET PILES Russian patent published in 2025 - IPC E02D5/04 

FIELD: construction.

SUBSTANCE: invention relates to sheet piles and sheet pile walls made from them and can be used in hydraulic engineering during construction of sea and river berths, as well as in construction in the ground of retaining walls for various purposes, for which additional reinforcement is not required. Proposed is a method of reinforcing a pipe-sheet pile wall, in which a sheet pile wall is mounted at least from sheet piles, on the lateral sides of which there are fixed elements of the tool joint, which are used to connect the sheet piles. Pads are welded onto the pipe surface, each of which is a segment of a cylindrical metal pipe of the same diameter as that used in the sheet pile, obtained by longitudinal sectioning. Sheet piles used are solid pipes; at least two pads are used for each pipe sheet pile, which are welded on both sides of the pipe symmetrically and at equal distance from the elements of the tool joint.

EFFECT: providing the possibility to replace each solution of traditional pipe-sheet piling solutions with large diameters by multiple pipe-sheet-piling solutions with smaller pipe diameters, besides, with excess of elastic moments and efficiency coefficients.
