T/SCDA 056-2020 - Pretensioned Prestressed Concrete Hollow Square Pile

Scope: The pre-tensioned prestressed concrete hollow square piles in this atlas are suitable for the low platform foundations of industrial and civil buildings, structures and other projects in areas with seismic fortification intensity of 7 degrees and structural fortification degrees of 8. It can be used as a reference when low-capacity pile foundations are used in railways, highways and bridges, ports, municipal administration, water conservancy and other projects. The pre-tensioned prestressed concrete hollow square piles in this atlas are designed for durability according to Class IIb environment, and the design service life is 50 years. When the basic environment and geological conditions are corrosive to the piles, the design service life exceeds 50 years. , strengthening measures should be taken according to the conditions of use and relevant specifications (among them, pre-tensioned prestressed high-strength concrete thin-walled hollow square piles are suitable for foundation treatment projects with shallow foundations).
