Scope

Scope: 1. This collection of drawings applies to low-pile foundation projects of industrial and civil buildings, structures, and municipal projects in areas with seismic fortification intensity of 7 or lower, using XC spring-loaded clip-type connected pre-stressed concrete piles. 2. The XC spring-loaded clip-type connected pre-stressed concrete piles in this collection are designed for durability under Class IIB environmental conditions. When the foundation environment or 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 clip-type connected pre-stressed concrete piles in this collection are suitable for withstanding vertical compressive loads and vertical uplift loads. When used to withstand large horizontal loads or in foundation projects where the piles are located in liquefiable soil layers (including a certain range near the interface between soft and hard soils), special design and verification calculations are required. Main technical content: The XC spring-loaded clip-type connected pre-stressed concrete piles (referred to as spring-loaded concrete piles) are pre-stressed concrete prefabricated piles manufactured using the prestressed method and joined by spring-loaded mechanical connections. This collection includes spring-loaded clip-type connected pre-stressed concrete tube piles (referred to as spring-loaded tube piles), spring-loaded clip-type connected pre-stressed concrete hollow square piles (referred to as spring-loaded hollow square piles), and spring-loaded clip-type connected pre-stressed concrete solid square piles (referred to as spring-loaded solid square piles). Among them, spring-loaded tube 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, wi
