Scope

Main technical content: 1. The DP pre-tensioned ultra-high strength concrete pipe piles (hereinafter referred to as pipe piles) are suitable for low-pile foundation projects of industrial and civil buildings and structures in areas with a seismic fortification intensity of 7 or lower. They can also be used in railway, highway, bridge, water conservancy and water transport, municipal, and power projects under the same technical conditions. 2. The pipe piles in this collection are designed for durability according to Class IIA and Class IIB environmental categories. When used in environments classified as Class III to Class V, corrosion prevention measures should be taken according to relevant specifications based on the usage conditions. 3. These pipe piles are mainly used in pile foundation projects that withstand vertical compressive loads and vertical uplift loads. When they simultaneously bear horizontal loads and seismic effects, designers should conduct additional design checks based on the design bearing capacity of single piles and the reinforcement structure of the pile body, taking into account geological conditions, project experience, and other factors. 4. When the pipe piles are used in liquefaction sites, designers should ensure their seismic performance through calculations and structural measures in accordance with current national standards.
