FIELD: oil and gas industry.
SUBSTANCE: method includes increasing the upper bearing surface area of the pile. A recess is made around the strengthened pile pier within a radius of 1.5 to 2.5 of the outer diameter of the pile (Dc) with a depth equal to the thickness of the necessary concrete layer. A reinforcing frame is mounted into the recess and the recess is filled with concrete. A metal support structure with reinforcing ribs is installed after concreting and fixedly connected to the aboveground part of the pile.
EFFECT: increased bearing capacity of the pile pier which is already installed and operated in the areas of permafrost soil by increasing the bearing surface area of the pile carried out at the daylight surface level.
