PURPOSE: To prevent sputter of water or exfoliated matters caused by high pressure water by using a rubber sheet to the wall surface and a sound isolating framework at the periphery of a working platform, and embodying a wall surface exfoliation working platform in which a suction pad for pushing and pulling with a cylinder is installed on the body of working platform.
CONSTITUTION: A body 1 is composed of a prop 2 and a sound isolating framework 3, and an elastic rubber sheet 4 is affixed to the part contacting the framework 3. This is hung by a wire 7. The body 1 is equipped with a suction pad 9 which is fitted with a waterproof box 8 and high pressure water nozzle 19 and is driven by a cylinder 10. The framework 3 is furnished with a hose 14, pipe 16 and holes 15, 16 so as to exhaust the high pressure water. The wire 7 is hung down during operation, stopped in place, and attracted to the wall surface by the suction pad 9, and the high pressure water 20 is spouted from the nozzle 19. This enables cleaning of the wall surface without sputtering of water or exfoliated matters caused by the high pressure water 20.
