Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and marking for pretensioned spun concrete special-shaped piles used in foundation engineering. It is applied in the construction industry for manufacturing and quality control of non-cylindrical piles (e.g., T-shaped or I-shaped cross-sections) that enhance soil-bearing capacity and reduce material usage in building and bridge foundations. The standard ensures structural reliability and consistency during pile production and field installation.
