Abstract

The invention relates to the technical field of geothermal energy, in particular to an energy pile structure and a construction method thereof. The energy pile structure comprises a tubular pile, a heat exchange body and an overhaul mechanism, wherein the tubular pile is arranged in a soil layer, the heat exchange body is sleeved with the tubular pile, a heat exchange pipe is arranged on the inner wall of the heat exchange body spirally, one end of the overhaul mechanism is arranged on the side wall of the heat exchange body, and the other end of the overhaul mechanism is arranged at the bottom end of the heat exchange body to be connected with the head end of the heat exchange pipe so that the overhaul mechanism can be used for replacing and overhauling the heat exchange pipe. The technical problems that in the prior art, a heat exchange pipe is prone to being damaged and not easy to replace and cannot be overhauled are solved.

Description

technical field [0001] The invention relates to the technical field of geothermal energy, in particular to an energy pile structure and a construction method thereof. Background technique [0002] With the increasing demand for energy, the large-scale use of fossil energy has brought about resource depletion and environmental pollution, while geothermal resources will not pollute or damage the human environment. Every 1% increase in geothermal utilization is equivalent to replacing 37.5 million tons of standard coal, reducing carbon dioxide emissions by about 94 million tons. [0003] However, the ground source heat pump technology occupies a large underground space, the drilling cost is relatively high and the heat transfer efficiency is low, which greatly limits the popularization and application. The energy pile heat storage technology is to turn the concrete pile foundation buried in the ground into a part of the heat storage heat exchange ground source heat pump system...
