Abstract

600388 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
