Title:
FULL-SCALE TYPE INSPECTION METHOD FOR STEEL-PIPE PILE WELDING SECTION
Document Type and Number:
Japanese Patent JP3905302
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the reliability of inspection by directly confirming the strength of a welding section by torsional torque working in constructing a steel pipe pile.
SOLUTION: The strength of the mutual welding joining sections of steel pipes in a rotary press-in type steel pipe pile is inspected by measuring torque working to the steel pipe pile during the construction works of the steel pipe pile in which a blade is fixed at a front end.
