1. DP pre-tensioned ultra-high-strength concrete pipe piles (hereinafter referred to as pipe piles) are suitable for low-cap pile foundation projects in industrial and civil buildings, structures and other projects in areas with seismic fortification intensity of 7 degrees and below. Low-capacity pile foundations can be used in railways, highways and bridges, water conservancy and water transportation, municipal administration, electric power, etc. under the same technical conditions. 2. The pipe piles in this picture are designed for durability according to the environmental categories of Class 2a and Class 2b. When used in Class 3 to Class 5 environments, anti-corrosion measures should be taken according to the conditions of use and relevant specifications. 3. The pipe piles in this figure are mainly used for pile foundation projects that bear vertical compression loads and vertical pull-out loads; when they bear horizontal loads and earthquake effects at the same time, designers should base their design bearing capacity on single piles and pile body configurations on The reinforcement structure shall be separately designed and calculated based on geological conditions, engineering experience and other factors, and selected after comprehensive consideration. 4. When pipe piles are used in liquefaction sites, designers should ensure their seismic performance through calculation and structural measures in accordance with current national standards.
