The invention discloses a steel pipe stand column positioning device and a positioning construction method thereof. The steel pipe stand column positioning device comprises a positioning frame and a working section, wherein a steel pipe column penetrates through a stand column hole of the positioning frame to enter a designed hole well, the working section is connected with the steel pipe column,an adjusting device on the positioning frame adjusts the perpendicularity of the steel pipe column through the working section, the steel pipe column is positioned by using the positioning frame and apositioner, and the perpendicularity of the steel pipe column is adjusted by the working section and a telescopic oil cylinder. According to the steel pipe stand column positioning device and the positioning construction method thereof, accurate positioning of the steel pipe column in a narrow construction site is realized, the positioning precision is high, stable and controllable, deviation iseasy to correct, the operation method is simple and convenient, the technical difficulty is low, tool equipment can be recycled, the cost is low, the economic benefit is obvious, super concrete capable of keeping plasticity for a long time is newly arranged, the problems that the steel pipe column is inserted into a pile foundation to be resisted, and pile pulling is difficult are solved, the steel pipe column construction method is changed into a positioning frame rear-inserting method, concrete pouring is carried out on the interior of the steel pipe column in advance, the positioning frameis subjected to line production, the construction efficiency is improved, and the construction progress is accelerated.
