Abstract  Through the project example we introduce the design and the construction characteristic laying down vertical closed-loop the heat interchanger between the construction pile or under the accepting heavy pat，In foundation carrying on the hydraulic pressure computation and in the strength calculation foundation , Propose the examination computation and its the method with the pipeline the pipe wall section different stability and the most greatly vertical distortion, also propose the computational method ofreasonable spacing between the pile and vertical closed-loopthe heat interchanger.

Key words  Vertical closed-loopheat interchanger between pile;Reasonable spacing; Link to stable computation; Vertical distortion computation; Backfill.
