NOVELTY - The structure has a water inlet pipe section connected with a geothermal pump (6) on a ground. A water outlet pipe section is connected with the heat collector (5) on the ground. The lower pile body is poured by concrete material doped with graphene. The heat exchange pipe (3) comprises a water inlet pipe section, a heat exchange pipe section and a water outlet pipe section. The water inlet pipe section is connected with the geothermal pump on the ground. The water outlet pipe section is connected with the heat collector on the ground. The heat exchange pipe section is pre-embedded in the lower baffle wall and the lower pile portion (2). The heat exchange tube is filled with heat exchange liquid. USE - Cast-in-place heat exchange pile-wall support structure for use in civil building and energy technology field. ADVANTAGE - The lower retaining wall improves the heat exchange efficiency, the insulating layer of the upper retaining wall can reduce the energy loss, after the engineering is finished, it not only serves as the permanent retaining structure of the slope, but also as heat exchange structure, so as to improve the utilization efficiency of the support structure. The insulating layers of the back soil side of the retaining wall prevent the heat from being transmitted to the hollow surface, reducing the energy dissipation on the upper part of the wall, and improving the whole heat transfer efficiency. The pile body improves the whole rigidity and shear strength of the pile-wall supporting structure, the supporting structure is embedded with a heat exchange tube as heat transfer structure, at the same time, performing the closed circulation conversion of geothermal energy, saves the associated cost of independently drilling the heat DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the construction method of cast-in-place heat exchange pile-wall support structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the heat exchange occlusive support structure. 2Pile portion 3Heat exchange tube 5Heat collector 6Geothermal pump 8Joint seam 9Plain ash pile 21Upper portion pile portion 22Lower portion pile portion
