Construction method of embedded pipe heat exchange pile and embedded pipe heat exchange pile structure

The invention discloses a construction method of an embedded pipe heat exchange pile and an embedded pipe heat exchange pile structure. The method comprises the steps that on the basis of existing pile foundation coring detection holes, heat transfer pipes and a backfill slurry, wherein the diameter of each coring detection hole ranges from 100mm to 150mm, embedded pipe form in the coring detection hole can be as follows, firstly, a closed type U-shaped circulation loop, secondly, an inside and outside concentric circle form, wherein an inner pipe is a water discharging pipe, and an outer pipeis a water feeding pipe, or thirdly, a circulation loop is formed between the third two core taking detection holes through pipelines pre-buried at the pile ends. The method has the advantages and effects that the coring detection holes of the existing pile foundation is utilized, and the heat transfer pipes are embedded in the coring detection holes so as to form an energy pile; and the construction does not interfere or influence the normal construction of the pile foundation, and the scheme is simple and the construction cost is low.
