Scope

Main technical content: This collection of drawings is suitable for low-pile foundation of industrial and civil buildings and structures in areas with seismic fortification intensity of 7 degrees and 8 degrees structural fortification, such as railway, highway, bridge, port, municipal, water conservancy and other projects. When using low-pile pile foundation in these projects, this collection of drawings can be used as a reference. The pre-tensioned prestressed concrete hollow square piles in this collection of drawings are designed for durability according to Class IIB environment, with a design service life of 50 years. When the foundation environment and geological conditions are erosive to the piles, and the design service life exceeds 50 years, strengthening measures should be taken according to relevant specifications based on the usage conditions (among which, the pre-tensioned high-strength concrete thin-walled hollow square piles are suitable for shallow foundation ground treatment projects).
