PILE WELDED SHEET Russian patent published in 2021 - IPC E02D5/04 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to metal tongue-tie for sheet tongue construction, and can be used in construction of moorings, locks, dams, etc. Pile welded sheet made in cross-section of wavy profile comprises flanges parallel to each other on opposite sides from central axis of panel cross-section, inclined walls located at an obtuse angle to the flanges, connecting adjacent ends of the shelves located on different sides from the central axis, two inclined semi-walls located on extreme flanges at an obtuse angle to the flanges and towards the central axis. One inclined semi-wall is equipped on the free end with the cam, the second inclined semi-wall is equipped on the free end of the cage, so that when the cam is inserted into the cage a locking connection is formed, cage is located on external, and cam – on inner surface of corresponding half-walls. Flanges, inclined walls, semi-walls are made of strips of structural steel containing carbon in range from 0.1 to 0.2 %, silicon in range from 0.4 to 1.1 %, manganese in range from 0.4 to 1.7 %, nickel in range of 0.1 to 0.8 %, chromium in range of 0.1 to 0.9 %, vanadium in range of 0.1 to 0.15 %, copper in range from 0.2 to 0.6 %, with yield point in range from 265 to 400 MPa, connected by welding.

EFFECT: technical result consists in improvement of sheet pile panel operational and technological characteristics, namely, increase in panels service life, id est increases sheet panel resistance to harmful (mechanical and corrosive) effects of environment, reduced metal consumption, facilitation of production process, provision of transportation and installation convenience.
