Masonry type building surface particle spraying retreading construction method

Abstract

The invention discloses a masonry type building surface particle spraying retreading construction method, which comprises the following steps: 1. building a construction platform; 2. spraying and cleaning particles (a pneumatic spray gun is adopted for carrying out particle spraying and cleaning construction at a uniform speed on the surface of masonry type buildings to be treated from top to bottom or from left to right, the caliber of the pneumatic spray gun is between 3 and 5 mm, the sprayed airflow outlet pressure is between 8 and 12 Pa, and in addition, the air outlet amount is between 1 m<3> / min and 3 m<3> / min); 3. carrying out later stage checking and supplementary spraying after the particle spraying and cleaning; 4. carrying out inactivation and sterilization cleaning; 5. patching defective holes; and 6. spraying and coating protective agents. The invention has the advantages of convenient construction, low construction cost, short construction period, high construction efficiency, good construction effect and high retreading quality, at the same time, the invention can not cause great pollution to external environment, and the invention has high economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of surface cleaning and refurbishment of masonry buildings, and in particular relates to a construction method for surface particle jetting refurbishment of masonry buildings. Background technique [0002] Buildings are called the monuments of human culture, and they are the most prominent objects that people perceive most visually. Its beauty and ugliness play a leading role in the quality of the urban environment. At the same time, since the surface of the building is exposed to the outside for a long time, it will inevitably be affected by various conditions such as physical, chemical and biological effects, and will eventually form on the surface of the building such as smoke and dirt, water-soluble salt, various colors of stone rust, difficult Covering layers or dirt such as soluble hard shells not only affect the overall cleanliness and aesthetics of the building, but also shorten the service life of t...
