Chimney anti-corrosion repair and renovation construction
First, the general situation of the project.
This project is a chimney anti-corrosion repair and renovation construction project, aiming to improve the anti-corrosion performance and service life of the chimney and ensure the normal operation of industrial production. The construction involved a 50-metre-high reinforced concrete chimney, which currently had serious corrosion problems and required a complete restoration and renovation.
Pay attention to the direct communication here, 24 hours dedicated to your service.
Second, the construction plan.
1.Surface treatment: First of all, the surface of the chimney is comprehensively cleaned and inspected to remove loose concrete, rust, dirt and other impurities to ensure that the surface is smooth, dry and free of oil stains. Then the cracks, defects and other parts are repaired to provide a good foundation for the subsequent anti-corrosion coating construction.
2.Anti-corrosion coating construction: According to the degree of corrosion and environmental conditions of the chimney, select suitable anti-corrosion coatings, such as silicone high-temperature anti-corrosion coatings, zinc-rich primers, etc. Multi-level coating is carried out according to the construction requirements of the coating to ensure the thickness and uniformity of the coating to achieve a good anti-corrosion effect.
3.Acid and alkali resistant lining: On the basis of anti-corrosion coating, the inside of the chimney is constructed with acid and alkali resistant lining, and corrosion-resistant materials such as glass fiber reinforced plastic, acid-resistant tiles, etc., are selected to improve the acid and alkali resistance inside the chimney and prevent the impact of corrosive media on the structure.
4.Waterproof treatment: After the lining construction is completed, the outside of the chimney is waterproofed, and materials with good durability and excellent waterproof performance are selected, such as waterproof membranes, waterproof coatings, etc., to enhance the waterproof performance of the chimney and prevent moisture from penetrating into the internal structure.
5.Monitoring and maintenance: After the construction is completed, the chimney is comprehensively monitored and maintained, the integrity of the anti-corrosion coating and lining is regularly checked, and the existing corrosion problems are found and dealt with in time to maintain the long-term stable operation of the chimney.
3. Construction organization and schedule.
1.Construction team: Set up a professional chimney anti-corrosion repair and renovation construction team, with rich construction experience and skill level, to ensure the smooth implementation of the project.
2.Construction equipment: select advanced construction equipment, such as cranes, lifts, high-pressure water guns, etc., to improve construction efficiency and quality.
3.Construction schedule: According to factors such as project quantity, technical difficulty and site conditions, formulate a detailed construction schedule, reasonably arrange the work tasks and time nodes of each stage to ensure that the project is completed on schedule.
4.Safety measures: During the construction process, strictly abide by the relevant safety regulations and operating procedures, and take effective safety measures, such as setting up safety nets, protective railings, etc., to ensure the safety and health of construction personnel.
5.Environmental protection: rational use of resources, reduce energy consumption and environmental pollution, comply with relevant environmental protection regulations and standards, and take effective environmental protection measures, such as controlling construction noise and dust emissions.
6.Quality assurance: Establish a sound quality management system, conduct comprehensive monitoring and testing of the construction process, and ensure that the quality of the project meets the relevant standards and customer requirements. At the same time, strengthen communication and coordination with customers, and timely process and feedback customers' opinions and suggestions.
7.Cost control: According to the project budget and the actual situation, formulate a reasonable cost control plan, and reduce the project cost by optimizing the construction plan and reducing material consumption. At the same time, financial management and auditing should be strengthened to ensure the rational use and transparency of project funds.
Fourth, the project acceptance and summary.
1.Project acceptance: After the completion of the project, organize relevant personnel to carry out the project acceptance work and check whether the construction quality meets the requirements. Rectify and improve the existing problems to ensure that the quality and safety performance of the project meet the expected goals.
2.Experience summary: During the construction process and after acceptance, a comprehensive experience summary and technical exchange will be carried out on the project, and the problems and solutions encountered in the construction will be summarized.
