METHOD FOR CONSOLIDATION OF PILE FOUNDATION FOR SUPPORT OF ELECTRIC POWER LINE Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: this is used in repair, restoration and maintenance operations on pile foundations of electric power line supports which are found in emergency or alarming conditions caused by soil heaving due to frost. According to method, consolidation of pile foundation for support of electric power line is effected by additional sinking of piles to design level. For this purpose, made at both sides of support axis are temporary anchors, and guy lines are attached to aforesaid anchors. By means of these guy lines, support is deviated from vertical position initially to one side then to another side only after preliminary disconnection of piles from each pair of support legs on which they are resting. After additional sinking of piles to design level, support is returned back to vertical position and legs of support are connected to finally sunken piles. Application of aforesaid method simplifies technology, reduces labour-intensity and cost of restoration work, also improves reliability of consolidated support foundation in its further operation. EFFECT: higher efficiency. 4 cl
