METHOD FOR CONSTRUCTION OF ANCHOR PILES Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: this relates to erection of pile anchors for fastening guys in ground for masts, aerial power line supports and other structures of tower-type in seasonally freezing swelling grounds. According to method, pile body is sunken in ground and after that pile body is connected to anchor link. Prior to sinking, probing is effected along axis of pile being constructed and determined is thickness of compacted layer of ground which is lying under active layer of ground. Head-piece of pile body is driven down below depth of seasonal freezing through depth of compacted layer of ground lying below active layer of ground. Penetration of pile body into ground is achieved by means of standard extension piece. Located between pile head-piece and lower boundary of seasonally freezing ground is rigid water-permeable diaphragm which is placed on bottom of drilled bore-hole. Aforesaid method simplifies technology of erecting anchor pile in seasonally freezing swelling grounds, enhances protection from heaving, increases load-bearing capacity. EFFECT: higher efficiency. 2 cl
