Scope

Main technical content: 1. This collection of drawings for ZC high-performance prestressed concrete special-shaped hollow square piles (hereinafter referred to as "ZC special-shaped square piles") is suitable for low-base vertical pile foundations of general industrial and civil buildings and structures in areas with seismic fortification intensity of 7 degrees and below. It can be used as a reference for the design of low-base vertical pile foundations in railway, highway, bridge, port, municipal, and water conservancy projects, but it should still comply with the provisions of current national and industry-related standards. When ZC special-shaped square piles are used in liquefaction sites, designers need to conduct a verification calculation and take effective structural measures to ensure their seismic performance. 2. This collection of drawings for ZC special-shaped square piles is designed for durability according to environmental categories IIA and IIB. When used in environmental categories III to V, corrosion prevention measures should be taken according to relevant specifications based on the usage conditions. 3. This collection of drawings for ZC special-shaped square piles is mainly used to withstand vertical compressive loads and vertical uplift loads in low-base pile foundations. When subjected to horizontal loads, designers should select or design separately after calculating and analyzing based on factors such as the engineering geology, load size, and construction conditions.
