Embodiment 1

[0041] In this embodiment, the construction platform is scaffolding, and the sealing layer is surrounded by tarpaulin or plastic cloth. In this embodiment, the caliber of the air pressure spray gun nozzle is 3mm, the pressure of the ejected airflow is 8Pa and the air output is 1m 3 / min, the moving speed of described pneumatic spray gun is 400mm / s; Particle (being quartz sand particle) jet cleaning construction process, the vertical spraying distance of described pneumatic spray gun is 40cm, and the injection direction of described pneumatic spray gun and The inclination angle between the surfaces to be treated in masonry buildings is 45°. In this embodiment, the building protection agent is an emulsion-type silicone water-repellent agent. After evenly spraying the protective agent, it can effectively reduce the water absorption performance of bricks, stones and other materials, and does not change the color and air permeability of the surface layer of the treated building, e...

Embodiment 2

[0043] In this embodiment, the difference from Embodiment 1 is that the caliber of the pneumatic spray gun nozzle described in step 2 is 4mm, the pressure of the ejected air flow is 10Pa and the air output is 2m 3 / min, the moving speed of the air-pressure spray gun is 800mm / s; Particles (i.e. corundum powder particles) jet cleaning construction process, the vertical spray distance of the air-pressure spray gun is 60cm, the spray direction of the air-pressure spray gun and The inclination angle between the surfaces of masonry buildings to be treated is 15°, and the rest of the steps are the same as in Example 1.

Embodiment 3

[0045] In this embodiment, the difference from Embodiment 1 is that the caliber of the pneumatic spray gun nozzle described in step 2 is 5mm, the pressure of the ejected air flow is 12Pa and the air output is 3m 3 / min, the moving speed of described pneumatic spray gun is 1200mm / s; Particle (being calcite powder particle) jet cleaning construction process, the vertical spraying distance of described pneumatic spray gun is 80cm, and the injection direction of described pneumatic spray gun and The inclination angle between the surfaces to be treated of masonry buildings is 90°, and the rest of the steps are the same as in Example 1.

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...
