PILE FOUNDATION FOR SITUATING SUPPORTS OF OVERHEAD POWER TRANSMISSION LINES

摘要

The invention relates to the field of energy, and more specifically to pile foundations for the supports of power transmission lines which are to be installed in various types of soil. The technical result consists in enhancing the reliability of the capacity of a pile to bear horizontal loads, in decreasing the labor-intensity and cost of carrying out operations, and in increasing reliability against forces of soil frost heave affecting the pile. A pile foundation contains a casing pipe and, positioned within same, a pile including a shaft and a heel, which is affixed in the lower portion of the shaft, wherein the pile contains rigid elements, which are installed on the shaft along the direction in which horizontal forces act on the pile from the effects of loads from overhead power lines, which are intended for transferring the horizontal forces from the pile to the casing pipe, and which are located on the shaft with a spacing between same of no less than the length of the rigid element.
