PURPOSE:To reduce incurring of a heat energy loss and to reduce a time and a man hour required between preparation of a repair work and restoration after completion of repair, by a method wherein hot water in the heat accumulating layer of a pond needing repair is transferred to other sound pond, and simultaneously, water in the fresh water layer and the non-convection layer of a sound pond is transferred to the pond needing repair. CONSTITUTION:A hot water return valve 14a of a pond A is brought into a closed state from an opening state, a solute recovery valve 15a is brought into an opening state from a closed state, and an outlet 8a is lifted to a position above a water surface. Hot water of a heat accumulating material 11a of the pond A is poured through an outlet 8b of a pond B to a heat accumulating material 1b of the pond B, water overflows fresh water layer 2b and flows through an overflow system 10b to a vaporizing pond 11. Water of a non- convection layer 3b also flows to the vaporizing pond 11, and after it joins a quantity of water overflowing the pond B, and the joined water is fed to the pond A with the aid of a solute recovery pump 12. Since the concentration and temperature of water in the pond A are reduced, a repair work in water is also facilitated. When a repair work is completed through reverse operation, high concentration hot water in the pond B is poured to the bottom of the pond A, and low concentration cold water overflowing the pond A flows to the surface of the pond B through the vaporizing pond 11. |
