NOVELTY - The new type utility claims one kind graphene modified energy pile, comprising pile body,, heat transfer tube cage, terrestrial heat pump and heat collector. Pile body sealing the bottom end, the top end of pile cap seal. Binding the middle heat transfer pipe up in steel cage in pile body internal. Two end heat transfer tube is extended, respectively connected with together and heat collector. Geothermal pump connected in series on heat transfer pipe up. The pile body is of mixture of graphene and concrete is formed. And heat transfer pipe with heat conducting liquid. Shape by sinking pipe pouring pile, prefabricate or cast-in-place. Heat transfer pipe is PVC pipe, PE pipe or metal pipe. Heat conducting liquid is graphene dispersing liquid. Using graphene and concrete composite material pile as the pile energy, it not only can increase heat transfer performance and heat storage capacity of pile body, also greatly increase have strength of pile body material.
