PURPOSE:To prevent the freezing of the ground around the tank effectively, and to secure the long-term stability of the tank body and the attached constructions by laying the heat generating pipe on the surface of the iron cage provided in the underground walls. CONSTITUTION:The water tank 9, the pump 10, and the drain 11 are provided to the underground tank 1, and the water in the tank 9 is supplied to the heat generating pipe 8 by the pump 10. By doing so, the continuous underground wall 2 is heated by the heat generating pipe 8 straying inside. Since the heat generating pipe 8 is layed, when the underground wall 2 is constructed, so that the pipe 8 contacts the iron cage 4, not only the cage is directly heated by the heat generating pipe 8 but the heat from the heat generating pipe 8 is conveyed to the iron cage 4 which can also serve as the heating source itself. Therefore, the underground wall 2 can be uniformly heated throughout the whole surface, and as the result, the freezing of the surrounding ground can be effectively prevented. |
