High-altitude exterior wall cleaning methods: hanging board (rope method), high-altitude lift vehicle, double-sided wiping method, trajectory window cleaning machine method, using environmental protection reagents to dissolve dirt, and flushing with high-pressure water guns.
1. Hanging board (rope method): Workers use the hanging board (rope) to slide down to the designated position for construction operations. This construction method is convenient and flexible. At the same time, it takes up less resources and can reduce the impact on the daily work and life of the owners. However, this method of operation must ensure that safety measures are in place, otherwise it will be very dangerous.
2. Aerial lift vehicles: The aerial lift method refers to equipment that can be used for high-altitude operations, such as lifts, spider vehicles, etc. Cleaners were sent to high areas, who then cleaned the exterior walls. This operation method has a high safety factor, but its use is limited and is only suitable for cleaning exterior walls below 36 meters.
3. Double-sided wiping method: Some glass windows are cleaned using double-sided magnetic glass scraping. This method can be operated indoors, but it has low efficiency and poor reliability, and is mostly used in the south. Due to the strong magnetic force, it has almost no impact on the insulating double-layer glass.
4. Orbital window cleaning machine method: In the construction process of exterior wall cleaning of some high-rise buildings, the movable track of the orbital window cleaning machine is reserved. When cleaning exterior walls, you can use an orbital window cleaning machine for cleaning. This cleaning method is relatively simple and relatively low cost.
5. Use environmental protection reagents to dissolve dirt: Wall cleaning solutions are generally divided into neutral detergents, alkaline detergents and pH detergents, but the most common ones are neutral detergents. When cleaning the wall, clean the surface with clean water first, and then use wall cleaning fluid. This method is suitable for cleaning all kinds of wall dirt. The cleaning effect is very good and the speed is faster.
6. Wash with a high-pressure water gun: loosen, separate, and dissolve the dirt, and rinse it away under high pressure. This method can clean dust, sediment and silt on wall materials, but this method requires attention to water consumption.
