Scope

Scope: 1. This atlas of XC spring-loaded connector pre-stressed concrete piles is suitable for low-pile foundation projects of industrial and civil buildings, structures, and municipal projects in areas with seismic fortification intensity of 7 or lower. 2. The XC spring-loaded connector pre-stressed concrete piles in this atlas 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 standards based on the usage conditions. 3. The XC spring-loaded connector pre-stressed concrete piles in this atlas are suitable for withstanding vertical compressive loads and vertical pulling loads. When used to withstand large horizontal loads or in pile foundation projects where the piles are located in liquefiable soil layers (including a certain range around the interface between soft and hard soils), special design and verification calculations are required. Main technical content: The XC spring-loaded connector pre-stressed concrete piles (referred to as spring-loaded concrete piles) are pre-stressed concrete prefabricated piles manufactured using the prestressed concrete technology and connected by spring-loaded mechanical methods. This atlas includes spring-loaded connector pre-stressed concrete pipe piles (referred to as spring-loaded pipe piles), spring-loaded connector pre-stressed concrete hollow square piles (referred to as spring-loaded hollow square piles), and spring-loaded connector pre-stressed concrete solid square piles (referred to as spring-loaded solid square piles). Among them, spring-loaded pipe piles and spring-loaded hollow square piles are collectively referred to as spring-loaded hollow piles. The connection method between the upper and lower sections of spring-loaded concrete piles is simple in structure, has reliable and direct force transmission, and is convenient for construction.
