Excuse me, how much does it cost to clean the external wall of Tongan?

Exterior wall cleaning is about 20-50 yuan per square meter, and the operation mode of exterior wall cleaning is as follows:

1. Operation mode of single spreader with seat plate: workers use the hanging plate (rope) to slide down to the designated position for construction. This construction method has the characteristics of convenience, flexibility and high safety factor. At the same time, it occupies less resources and can minimize the impact on the daily work and life of the owners.

2. Hanging basket method: Set a hanging basket on the roof to transport workers to the designated location for construction. This construction method has low cleaning efficiency and high cost.

3. High-altitude spider car: use platform equipment such as spider car and lift car to transport workers to designated places for construction work. This construction method has great limitations and is generally suitable for difficult projects below 36 meters. Because of the high cost, it is rarely used.

4. Track window cleaner: Track window cleaner is special for some high-rise buildings. This construction method is the same as the hanging basket method, but it is easy to move.

5. Indoor double-sided wiping mode: Some external windows of the glass are cleaned by double-sided magnetic glass scrapers, which can also be operated indoors, but it has low efficiency and poor reliability and is widely used in the south. Because of the magnetic force, it has little effect on the hollow double-layer glass.
