FIELD: construction.SUBSTANCE: driven pile comprises a helical shaft. The helical shaft is mounted from sections assembled from two identical subsections, made of even number (at least four) identical isosceles triangles, which are connected by turns along the perimeter of the subsection with four identical equilateral triangles, to form a small and a large end holes in the form of polygons. Two subsections are joined into a section with each other by sides of end large holes. Sections are connected to each other along the length of the helical shaft by their sides of small end holes, to form a multi-turn helical shaft of conventionally cylindrical shape, with mutually directed broken helical lines.EFFECT: increased bearing capacity, reduced forces of submersion and material intensity, expanded process capabilities.7 dwg |
