PURPOSE:To prevent the collapse of earth and sand and clogging of a water permeating tube by concentrically disposing the water permeating pipe around the outer periphery of a heat pipe, interposing a water permeating body around the outer periphery of the water permeating pipe, and embedding the heat pipe into the soil. CONSTITUTION:A heat pipe 2 is disposed at the center within a pipe 1 for burying, and water permeating pipes 10 made of plastic pipes of a retuculate shape are concentrically provided. The pipe 7 for burying is embedded into the soil where boring has been carried out beforehand, and a water permeating body 11 such as gravel or the like is filled in a space formed by the pipe 7 and the water permeating pipe 10. Then, the pipe 7 for burying is drawn out and the heat pipe 2 is embedded into the soil. That is since the water permeating pipe 10 is concentrically disposed around the outer periphery of the pipe 2, the collapse of earth and sand the damage of gravel and the damage of fins are prevented. Further, since the gravel 11 or the like is interposed around the periphery of the water permeating pipe 10, the water permeating pipe 10 is prevented from clogging. |
