PILE FOUNDATIONS FOR SUPPORTING POWER TRANSMISSION TOWERS
First Claim
1. A pile foundation for supporting horizontal and vertical loads in substrates susceptible to frost heaving, the pile foundation comprising:
- a casing pipe;
an immersed pile comprising a shaft and a toe bulb secured at the bottom of the shaft, positioned in the casing pipe;
rigid elements mounted on the shaft transverse to horizontal forces acting on the pile and configured for transferring the horizontal forces from the pile to the casing pipe.

Abstract
Pile foundations for power transmission towers or the like are installed in different types of soil prone to frost heaving. The pile foundations provide bearing capacity against horizontal loads, reduce labor content and installation cost, and increase reliability against the impact of frost heaving forces of the soil on the pile. The pile foundation has a casing pipe and a dipped pile, comprising a shaft and a toe bulb, secured at the bottom of the shaft. The pile comprises rigid elements that are mounted on the shaft in the direction of horizontal forces acting on the pile against the anticipated horizontal loads. The rigid elements transfer horizontal forces from the pile to the casing pipe.
