Screw piles

DICK GRAEME

There is provided a screw pile of hollow-cast steel having a tapered body (10), a stepped mounting portion (11), a reinforcing collar (12) and a helical flight (13). The tapered body (10) has an upper portion (14) and a lower portion (15) of sharper taper converging to point (16). The mounting portion (11) includes spigot portions (20) adapted to pass into selected cylindrical hollow section (CHS). The reinforcing collar (12) has an upper transition taper (23) which forms a land to which oversize CHS can be welded. The flight (13) has a maximum diameter at its upper turn (26). The upper turn (26) is formed integrally with the reinforcing collar (12) and transitions to the upper tapered portion (14). The helical flight (13) tapers in substantial proportion to the respective tapers of the tapered body (10).
