Pda test qualification standard of pha pipe pile

The pda test qualification standards for pipe piles are as follows:

According to the Specification for Pretensioned Prestressed Concrete Pipe Piles (JGJ/T406-20 17), the inspection standards for PHA pipe piles include three points:

1, the compressive strength of PHA pipe pile should not be less than 90% of the design requirements.

2. The bending strength of 2.PHA pipe piles should not be less than 90% of the design requirements.

3. The ultimate tensile strength of 3.PHA pipe piles should not be less than 90% of the design requirements.
