PURPOSE:To reliably supply a fixed high-pressure water by diverging a pipeline from a high-pressure water supply pump to be connected to pressure water requiring apparatus. CONSTITUTION:A high-pressure water pump 9 is operated to feed water to high- pressure water requiring apparatus such as a decontaminating apparatus 5 of atomic power generation plant, a terminal nozzle 4 of a hydraulic test apparatus 6 and the like to conduct an assigned work or a hydraulic test. In case of making a hydraulic test, the hydraulic test apparatus 6 is installed at a designated temporary construction position, and connected to the terminal nozzle 4 for a temporary construction apparatus, which is disposed for a floor 14, to conduct a fixed hydraulic test. In this case, when an open and close valve 13 of the terminal nozzle 4 is opened unexpectedly to jet high-pressure water, the high-pressure water strikes against only the floor 14, and there is no possibility that a worker or peripheral apparatus will suffer from jetting of high-pressure water. |
