[0002] The Chinese utility model patent with announcement number CN210288394U proposes a pile foundation construction positioning device, including a frame and positioning steel bars vertically fixed in the center of the pile, as well as a positioning cylinder with a top opening and an insertion hole for inserting the positioning steel bars, wherein the insertion hole is opened in the center of the bottom of the positioning cylinder.

[0003] The insertion holes on the positioning tubes in the above-mentioned technical solution are aligned with the positioning rebar for insertion. Using the positioning tubes instead of traditional white lime outlines allows workers to align the pile foundation with the positioning tubes during installation. The positioning tubes also serve as guides during installation, positioning the pile foundation, reducing errors after completion, and improving pile foundation quality. However, because the positioning tubes are open at the top and only have insertion holes at the bottom, they can interfere with pile foundation construction. Furthermore, their installation at one end of the mounting rod causes the device to be offset from the center, resulting in poor stability.

[0004] To this end, the utility model provides an auxiliary positioning and guiding device for pile foundation construction. Utility Model Content
