Scope

Main technical content: 1. The pre-tensioned concrete mechanical-connected solid square piles in this collection are suitable for low-pile foundation projects of industrial and civil buildings and structures in areas with seismic fortification intensity of 7 or lower. They can also be used as reference for low-pile foundation projects in railway, highway, bridge, port, municipal, water conservancy, and power communication projects. 2. The pre-tensioned concrete mechanical-connected solid square piles in this collection are designed for durability in Class IIb environments. When the foundation environment and geological conditions are erosive to the piles, anti-corrosion measures should be taken according to relevant specifications based on the usage conditions. 3. The pre-tensioned concrete mechanical-connected solid square piles in this collection are primarily suitable for withstanding vertical compressive loads. When used in pile foundation projects subject to vertical uplift loads, the joints must adopt anti-uplift joint connections. For pile foundation projects subject to large horizontal loads, special design and verification calculations are required.
