FOUNDATION STRUCTURE OF STEEL PIPE POLE

摘要

PROBLEM TO BE SOLVED: To prevent a steel pipe pole from collapsing/being broken in a foundation section of the steel pipe pole concerning a foundation structure of the steel pipe pole. SOLUTION: The foundation structure of the steel pipe pole constituting the foundation section of the steel pipe pole 1 erected involves an inner insertion pipe 10 being a support in a state where the steel pipe pole may collapse in the foundation part in a condition that an outer diameter is thinner than the inner diameter of the lowermost end and a length is equal to or higher than the height of a rib 4 in the foundation section of the steel pipe pole so as not to collapse in the foundation section by welding and joining the steel pipe pole being a tapered pipe, a base plate 5 and the rib 4.
