COMBINED SHEET PILE WALL Russian patent published in 2023 - IPC E02D5/02 

FIELD: combined sheet pile walls.

SUBSTANCE: invention can be used in hydraulic engineering in the construction of sea and river berths, as well as in civil and industrial construction. The combined sheet pile wall includes load-bearing piles made of pipes, connecting elements welded to the outer surfaces of the pipes with tongue and groove locks for connection with closing intermediate sheet piles located in the gaps between adjacent load-bearing piles. Closing intermediate sheet piles are made trough-shaped in cross section and at least one is placed in each gap between adjacent bearing piles, it is equipped with additional sheet piles, each of which is cut lengthwise into two halves, with each connecting element made from half of the said cut along the additional sheet pile and shear welded to the pipe in this manner. The welded section of each connecting element is located on the neutral axis of the sheet pile wall, and the locks of all connecting elements face the same direction relative to the neutral axis of the sheet pile wall.

EFFECT: ensuring creation of a unified design of the combined sheet pile wall, which is made entirely of elements of domestic production and has high tightness and strength.
