SPUD PILE Russian patent published in 2017 - IPC E02D5/56 

FIELD: construction.

SUBSTANCE: spud pile includes a helical barrel made of hollow and perimeter mounted from guide elements made in the form of three rectangular strips with overlaps bent alternately in opposite directions at an angle of 140° on incisions made at an angle of 60° to each other and to the longitudinal edges of the strips with the formation along the length of the strip of equilateral triangles arranged alternately in opposite directions. The strips are joined one to the other along the longitudinal edges at an angle of 70° with formation of three broken screw grooves on the inner perimeter of the main direction and one broken screw groove of the opposite direction; on the outer perimeter - three broken screw lines of the main direction and one broken screw line of the opposite direction, at the fracture points of which there are places of convergence of the sides of six equilateral triangles. Along the perimeter of the spiral shaft, rectangular-shaped irregularities are formed and located successively one after another along broken spiral lines of the main direction.

EFFECT: facilitation of the dipping of the trunk into the ground, simplification of manufacturing and expanding technological capabilities.
