Cast-in-place reinforced concrete horizontal enclosure energy pile

A cast-in-place reinforced concrete horizontal enclosure energy pile is characterized in that a plurality of earth-facing side U-shaped heat exchange tubes are arranged on the earth-facing side in a pile body at intervals, and a plurality of earth-facing side U-shaped heat exchange tubes are arranged on the earth-facing side in the pile body at intervals; a heat insulation plate used for isolatingheat exchange between the U-shaped heat exchange pipe on the soil backing side and the U-shaped heat exchange pipe on the soil facing side is arranged in the pile body. Two pipe orifices of the U-shaped heat exchange pipe on the back soil side are respectively communicated with a first inlet and a first outlet of the hot water tank; two pipe orifices of the U-shaped heat exchange pipe on the soilfacing side are respectively communicated with a first inlet and a first outlet of the cold water tank; a second inlet of the hot water tank and a second outlet of the hot water tank are respectivelycommunicated with an inlet
