Basic Information
Scope
Main technical content: 1. The square piles in this collection are suitable for low-pile foundation applications in industrial and civil buildings and structures with seismic fortification intensity of Grade 7 and Category B, as well as in railway, highway, bridge, port, municipal, and water conservancy projects. They can be used as reference for low-pile foundation applications in such projects. 2. The square piles in this collection are designed for durability in a Class IIB environment. When the foundation environment and geological conditions are erosive to the piles, and the design service life exceeds 50 years, appropriate reinforcement and corrosion prevention measures should be taken according to relevant standards based on the usage conditions. 3. The square piles in this collection are suitable for pile foundation projects subject to vertical compressive loads and vertical uplift loads. When used in pile foundation projects subject to large horizontal loads, special design and verification calculations should be conducted.
