Description

Technical Field

[0001] This application relates to the field of concrete pile technology, and more specifically, to prestressed steel tube concrete pile structures and their construction methods. Background Technology

[0002] Concrete piles are piles made of concrete (including ordinary reinforced concrete and prestressed concrete). The main function of a pile is to transfer the load to the surrounding soil through the contact between the pile side surface and the surrounding soil to obtain pile side resistance. As the load increases, the load is transferred to the deeper pile end soil layer to obtain pile end resistance.

When the concrete dries slowly and has a certain degree of fluidity, the quality of the concrete piles is low and their practicality is not high. Summary of the Invention
