METHOD FOR STABILIZING FOUNDATION OF AERIAL POWER LINE SUPPORTS Russian patent published in 1998 - IPC

FIELD: aerial power line construction. SUBSTANCE: this is used in construction area and namely in carrying out repair and maintenance operations on existing aerial power lines which are in emergency or dangerous condition. According to method, pile foundation of aerial power line support which is subjected to extracting load is reinforced by sinking anchor piles into ground and connecting them by links with foundation piles. Anchor piles are arranged at opposite sides with respect to longitudinal axis of aerial power line on straight line which passes through geometric center of foundation and perpendicularly to longitudinal axis of aerial power line. Each anchor pile is connected by links to nearest pair of foundation piles. Spacer beam is installed between head-pieces of pair of anchor piles located coaxially at different sides of longitudinal axis of aerial power line. Each anchor pile can be made up of two longitudinal components placed close to each other. Each of these components is connected to its pair of foundation piles which is most distant from it. Aforesaid arrangement simplifies performance of operations, reduces labour-intensity, enhances reliability of stabilizing foundation of aerial power line support in ground during further operation. EFFECT: higher efficiency. 1 cl, 2 dwg
