Abstract

Забивная свая, включающая винтовой ствол, отличающаяся тем, что винтовой ствол выполнен по периметру в виде пустотелой конической винтовой поверхности, изготовленной из полос криволинейной формы различного порядка и степени кривизны с центрами, расположенными снаружи поперечного сечения пустотелой конической винтовой поверхности с образованием по ее периметру многозаходных винтовых поверхностей вогнутой формы с винтовыми линиями и винтовыми канавками снаружи винтовой поверхности с разными размерами по ширине полос с увеличением их по длине конической винтовой поверхности, свернутых в вертикальной плоскости в продольном направлении и изогнутых по винтовым линиям в поперечном направлении на оправке в виде параболоида вращения, причем по наружному периметру винтовой поверхности снаружи образованы винтовые напуски по всей длине винтового ствола.A driven pile comprising a helical shaft, characterized in that the helical shaft is made around the perimeter in the form of a hollow conical helical surface made of strips of curvilinear shape of various orders and degrees of curvature with centers located outside the cross section of the hollow conical helical surface with the formation of multi-start along its perimeter concave helical surfaces with helical lines and helical grooves on the outside of the helical surface with different sizes along the width of the strips with increasing and along the length of the conical screw surface, folded in a vertical plane in the longitudinal direction and curved along helical lines in the transverse direction of the mandrel in the form of a paraboloid of rotation, with the outer periphery of the screw surface formed externally screw overlaps over the entire length of the screw stem.

Claims
