FIELD: construction industry.
SUBSTANCE: reinforcement method of pile foundation of power transmission line support on weak base provides for reinforced zone made around pile and under its edge in soil mass by boring the boring tool into soil mass without bringing bored soil to the surface to the depth exceeding depth of pile location, with further rotation of screw boring tool in reverse direction with simultaneous application of axial force directed downwards, the value of which is accepted as equal to the specified value of design resistance of compacted soil. During rotation of screw boring tool in reverse direction, additional volume of soil and/or strengthening disperse and bonding material or expanding material, for example foamed polyurethane, is introduced to reinforced zone.
EFFECT: simplifying reinforcement procedure of pile foundation of power transmission line support, increasing efficiency and reliability, reducing labour input and material consumption.
