1. Preparation before construction.
1.Personnel preparation: select an experienced chimney maintenance construction team to ensure that the construction personnel have the corresponding technical qualifications and operation experience.
2.Equipment preparation: According to the construction needs, prepare corresponding equipment, such as scaffolding, pulleys, wire ropes, hanging baskets, etc., to ensure the safety and reliability of the equipment.
3.Material preparation: According to the design requirements, select qualified crack repair materials, such as epoxy resin, polyurethane, etc., to ensure that the quality and performance of the materials meet the requirements.
4.Safety preparation: Formulate detailed safety operation procedures and equip necessary safety protection equipment, such as safety belts, safety helmets, etc., to ensure construction safety.
5.Environmental preparation: clean up the construction site, remove debris and obstacles, and ensure that the construction environment is clean and orderly.
Second, the construction process.
1.Crack detection: Use professional testing instruments to detect chimney cracks, record the location, direction, width and other information of cracks, and provide a basis for subsequent repair work.
2.Crack cleaning: Use sanders, sandpaper and other tools to clean the crack surface to remove dirt, loose concrete and other impurities to ensure that the repair material and the crack can be tightly combined.
3.Crack repair: Depending on the type and severity of the crack, select the appropriate repair material and process. For smaller cracks, surface coating or grouting can be used to repair them; For larger cracks, pressure grouting can be used to repair them. In the repair process, the close combination of the repair material and the crack should be maintained to avoid hollowing and falling off.
4.Anti-corrosion treatment: Anti-corrosion treatment is carried out on the repaired chimney to improve its durability and service life. Anti-corrosion treatment can be done by coating coating, FRP anti-corrosion and other processes. In the coating process, the thickness and uniformity of the coating should be controlled to avoid problems such as missing coating and flowing.
5.Quality inspection: Carry out quality inspection on the repaired chimney, including visual inspection, crack detection, etc. If quality problems are found, rectification should be carried out in time. At the same time, during the construction process, the construction quality should be regularly inspected and evaluated to ensure that the construction quality meets the requirements.
3. Post-construction inspection.
1.Visual inspection: Conduct a visual inspection of the repaired chimney to see whether the repaired part is smooth and smooth, and whether there are problems such as color difference and bubbles. If a problem is found, it should be dealt with in a timely manner.
2.Crack detection: Crack detection is performed on the repaired chimney to see if the cracks have been completely closed and if there are new cracks. If new cracks are found, they should be repaired in a timely manner.
3.Durability test: Durability test is carried out on the repaired chimney, including compressive strength test, impermeability test, etc. If the test results do not meet the requirements, they should be reinforced or repatched in time.
4.Regular maintenance: Perform regular maintenance on the repaired chimney, including cleaning the surface, checking the anti-corrosion layer, etc. If damage or aging is found, it should be dealt with in a timely manner.
In short, chimney crack repair is a special project with high technical requirements and difficult operation. When carrying out chimney crack repair construction, certain steps and requirements need to be followed to ensure the quality and safety of construction. At the same time, in the construction process, quality inspection and control should be strengthened, and problems should be found and dealt with in a timely manner to ensure that the construction quality meets the requirements.
