[0002] High-performance prestressed concrete hollow support piles are a structural support system, usually used in foundation pit support, river bank reinforcement, bridge foundation and other projects. Due to its reliable structural performance, large cross-sectional stiffness, simple and easy construction, and beautiful molding effect, it has been used in small and medium-sized river regulation, waterway management, sea reclamation, municipal drainage, road subgrade support and urban foundation pit projects.

[0003] However, most of the current high-performance prestressed concrete hollow support piles have the following problems:

[0004] 1. Existing high-performance prestressed concrete hollow support piles are prone to misalignment of the center line when they need to be installed for high-rise construction, resulting in deviation and tilt, which affects the stability of use and is inconvenient for high-rise construction.

[0005] Second, the existing high-performance prestressed concrete hollow support piles have a relatively simple connection method when they are installed side by side, resulting in a relatively large gap between them, poor waterproof and retaining effect, and the side-by-side hollow support piles are prone to tilting during use, which affects the stability of use and is inconvenient to be firmly connected for use.

[0006] Therefore, we made improvements and proposed a high-performance prestressed concrete hollow supporting pile. Utility Model Content
