A heat storage body formed underground by solidifying ± (sand) with a soil solidification material, a ventilable heat exchange passage formed inside the heat storage body, and a heat storage body filled with water. An underground heat storage structure comprising: a heat storage member disposed within the heat exchange path; 2. Excavate the site to form a hole or groove of arbitrary length, width, and depth, then place a flexible heat storage tube filled with water in the groove (hole), and then fill it with water. A flexible tube for forming a conduit containing a small amount of water is placed and arranged so as to cover the heat storage tube from above, and at least both ends of the tube for forming a conduit are placed outside the groove (hole). In the exposed state, sand mixed with soil solidification material was poured into the trench (hole) so as to surround and bury the two wooden tubes mentioned above, and then the poured sand was solidified. After that, water is drained from the pipe forming tube 7 and only that tube is pulled out and removed, thereby forming a heat storage body made of solidified ± (sand), a ventilable heat exchange path, and a heat storage member filled with water. 1. A method for forming an underground heat storage structure. 3. Excavate the site to form a hole or groove of arbitrary length, width, and depth, then place a flexible pipe-forming tube filled with water in the groove, and then install the tube. With both ends of the tube exposed to the outside of the trench, earth and sand mixed with a soil solidification material are poured into the trench so as to surround and bury the tube.Next, after the poured earth and sand has solidified, the tube is removed. Then, a flexible tube with a smaller diameter than the tube is connected to one end of the tube for forming a conduit, and is removed from the other end of the tube for forming a conduit, and the small diameter tube is inserted into the conduit. and then filling the small diameter tube with water, thereby forming a heat storage body made of solidified earth and sand, a heat exchange path that allows ventilation, and a heat storage member filled with water. A method for forming an underground heat storage structure.
