Background Art

[0002] Micro bored piles (hereinafter referred to as micro piles) are bored piles with a smaller diameter, generally ranging from 100 to 300 mm in diameter. They are widely used in small and medium-sized industrial and civil buildings with small and dispersed loads. Due to the small diameter of micro piles, the thickness of the concrete protective layer of the steel cage of the micro pile foundation is difficult to control during processing and construction. The specifications and quality of the finished steel cage vary. When the spacing of stirrups at different positions of the pile body is different or spiral stirrups are used, the spacing of stirrups is difficult to control, the construction progress is slow, and the quality of the finished steel cage is difficult to meet the specifications and design requirements, which ultimately easily causes quality and safety problems in cast-in-place piles. Therefore, how to effectively control the size and specifications of the micro pile steel cage during processing, ensure the processing quality of the steel cage, and improve the convenience of processing and construction has become a problem that needs to be solved urgently.
