FIELD: construction.
SUBSTANCE: passage rotor for mounting screw pile from polyangular profile pipe includes a housing with leading gears, driven rotary gear having a polygonal profile hole in the middle, longitudinally and rotationally movable grip with a similar profile polygonal hole, inserted in the hole of a driven gear. Cross-section of profile hole of the rotor is governed by the replaceable inserts, which are fasteners with screws to the longitudinally movable rotating pile grip, wherein each insert has a size and shape that is different from the size and shape of other inserts in the set.
EFFECT: improvement of the quality of installation of piles with preservation of its bearing capacity due to exclusion of incision and punching piles for its installation, method of rotation of pile with profiled shoulder anywhere on the pile trunk, providing free turning, wringing of piles in clay, precluding the use of drilling rigs and crane carriages.
