T/SCDA 165-2025 Pre-stressed Concrete Hollow Octagonal Piles by the First Tensioning Method
T/SCDA 165-2025 Prefabricated prestressed concrete hollow octagonal pile using the pre-casting method
Basic Information
Scope
Main technical content: This atlas mainly applies to the pre-tensioned concrete hollow octagonal piles, which are suitable for general industrial and civil buildings, water conservancy, municipal, railway, highway, bridge, port and other engineering fields in areas with a seismic fortification intensity of 7 degrees or less. They are used for supporting and retaining slopes or revetments in these areas, and should comply with the provisions of the current national and industry-related standards. When used in liquefaction sites, designers should ensure their seismic performance through calculations and structural measures in accordance with current national standards. This atlas designs the pre-tensioned concrete hollow octagonal piles based on Class IIB concrete structures, and when used in Class III to Class V environments, anti-corrosion measures should be taken according to the relevant specifications based on the usage conditions.
