DRIVE TYPE HEAT INSULATION PIPING FOR THERMAL STORAGE WATER TANK, STRUCTURE OF HEAT INSULATION WATER TANK USING THE PIPING, AND METHOD OF EXECUTING INSTALLATION WORK OF THE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To realize the structure of a thermal storage water tank having remarkably improved and modified installation workability of a heat-insulated communication pipe for interconnecting the tanks of the thermal storage water tank and a low possibility of water leakage. SOLUTION: Driven type heat insulation piping formed of a synthetic resin foam or an inorganic foam having strength high enough to be durable against a pressure during placing of concrete for a foundation beam 4 is used as heat insulation piping 6 for interconnecting the tanks of a site building type thermal storage water tank 1. A heat insulation layer 7 formed of the same material as that of the heat insulation piping 6 is formed on the inner surface of the thermal storage water tank 1, and a waterproof layer 8 formed of the same material is formed continuously to the heat insulation layer 7 and the heat insulation piping 6.
