概要
In the undergrounding pipe-space, there are many pipes for utility (electronic cable, water, gas, steam, etc.). These pipes are kept to safe by daily inspect ion. But hot environment of the pipe-space affects badly the device and a labor er's health.The investigation of the heat distribution was carried on, therefor e it was found that the radiant heat around the valve was very much. The method of thermal insulation was examined from the view point of the shape, cost, and effect. Then some of valves were covered with flexible thermal insulation, and the temperature of the area around the covered valves was decreased about 10°C.
