Practice on the application of concrete filling pile under -20 C to -30 C in the cold areas of China. Using special metsl drill bit to bore under bitter cold temperature. To keep concrete strength increasing normally, the content of antifreezing admixtures which is added into concrete piles varies with underground frozen soil temperature. Choosing proper structure shape and construction method to eliminate or reduce the influence of soil's frost heave force upon concrete filling pile and bearing plate.
