Abstract
An anti-jacking pile solution particularly suited for use in permafrost or cold regions. The pile includes bond breaking material for preventing frozen soil from directly gripping a pile near the surface of the soil and pulling the pile upward. A collar is attached to the pile to prevent damage and/or displacement of the bond breaking material during driving of the pile. The pile may be attached to a building by way of an adjustable connection system allowing for future adjustments in the event of vertical movement.
Claims8
A method of installing an anti-jacking pile system, comprising the steps of;
- a) wrapping a section of outer surface of a pile with a bond breaking material, said section having an upper end and a lower end;
- b) attaching a collar at a location adjacent said bond breaking material at said lower end of said section and further attaching said collar directly to said outer surface of a pile for protecting said bond breaking material from being damaged by the surrounding soil during driving of said pile;
- c) driving said pile into soil a sufficient depth to act as a support for a building.
