SHORING METHOD FOR PILES FOUNDATION OF POWER TRANSMISSION POLE Russian patent published in 2004 - IPC

FIELD: building industry, particularly shoring of piles foundation subjected to pressing in and pulling out forces, particularly because of soil frost heaving. SUBSTANCE: method involves driving at least two anchor rods into soil at the distance of 2 - 3 maximum dimensions of pile cross section from each pile axis and at the angle of 3 - 5 deg. to pile axis, connecting anchor rods with foundation piles by draw bars. Depth of rod driving is calculated by given relation. EFFECT: simplified repair-and-renewal technique, increased securing strength and reliability, prevention of foundation deformation, improved anchoring abilities to withstand pulling out forces and to resist soil frost heaving. 7 cl, 3 dwg, 1 ex
