Novel miniature concrete-filled steel tube pile structure

The utility model discloses a novel miniature steel pipe concrete pile structure which comprises a concrete pipe pile, an isolation sleeve and a steel pipe system structure, and the steel pipe system structure is mainly composed of a stress steel pipe, a limiting supporting rod, a limiting steel plate and other components. And the isolation sleeve is located between the concrete pipe pile and the steel pipe system structure and used for isolating the concrete from the steel pipe. The stress steel pipe and the concrete pipe pile are restrained by the limiting steel plate and the limiting supporting rod, and the stress steel pipe is tightly attached to the isolation sleeve, so that the stress steel pipe and the concrete pipe pile are stressed together. And the limiting supporting rod is an important restraining part of the steel pipe system structure, is located in the supporting rod cabin and is expanded and contracted through the pulling and pressing rod. The construction method of the novel miniature steel p
