摘要： PROBLEM TO BE SOLVED: To provide an epoch-making washing device capable of easily, inexpensively, and well washing, for example, bridges.
SOLUTION: This washing device comprises a water supply hose 4 having a submerged pump 3 at the front end and a water storage part 5 for storing the water supplied through the water supply hose 4. During the washing, a predetermined amount of water is stored in the water storage part 5 and a high-pressure pump 1 is driven to supply a predetermined amount of water from the water stored part 5 in which a predetermined amount of water is stored beforehand to the high-pressure pump 1 even if the supplied amount of water through the water supply hose 4 is increased or decreased. Therefore, the idle driving of the high-pressure pump 1 is prevented from occurring. A filter part 6 for removing impurities from the water is installed in the water supply passage from the water supply hose 4 to the portion where water is supplied to the high-pressure pump 1 through the water storage part 5. The water supply hose 4 is set longer so as to be suspended from the upper part of the bridge toward a river under the bridge and the submerged pump 3 at the end and submerged in the river.
