FIELD: power industry.
SUBSTANCE: pile foundation for arrangement of supports of an overhead power transmission line includes a casing pipe and a pile arranged in it, which includes a shaft and a shoe fixed in the lower part of the shaft. A pile is provided with stiff elements that are installed on the shaft in the direction of action of horizontal forces on the pile due to action of loads from supports of the overhead line, which serve for transfer of horizontal forces from the pile to the casing pipe and located on the shaft with a pitch of not less than length of a stiff element.
EFFECT: increasing carrying capacity of a pile on horizontal loads; improving reliability due to action of forces of frost boil of the soil on the pile; reduction of labour input and material consumption for execution of works.
