Special construction plan for chimney slipform
First, the general situation of the project.
This project is a chimney project of a thermal power plant, with a chimney height of 75 meters and a diameter of 45 meters, using sliding form construction technology for construction. This project has the characteristics of high-altitude work, difficult construction and high safety risk, so it is necessary to formulate a detailed construction plan to ensure construction safety and quality.
Pay attention to the direct communication here, 24 hours dedicated to your service.
Second, the construction process.
1.Preparation for construction.
1) Technical preparation: familiar with the drawings, understand the construction requirements and technical standards, prepare detailed construction plans and safety technical measures, and make technical disclosures.
2) Material preparation: According to the design requirements and construction needs, purchase qualified formwork, steel bars, concrete and other materials, and carry out quality inspection and acceptance.
3) Machinery and tools preparation: according to the construction needs, prepare complete construction machinery and tools, such as jacks, sliding form devices, welding machines, etc.
4) Labor preparation: according to the requirements of the project quantity and construction period, organize a sufficient number and skills of construction personnel, and carry out safety education and training.
2.Foundation construction.
1) On the basis of the chimney, measure and pay off according to the design requirements, and determine the center and radius of the chimney.
2) According to the design requirements, carry out foundation excavation and concrete cushion pouring.
3) Install the sliding form device on the cushion, and carry out debugging and acceptance.
3.Slipform construction.
1) Install the formwork on the sliding formwork device, and check the flatness and verticality of the formwork.
2) Tie the steel bar on the formwork and carry out quality inspection.
3) Concrete is poured, vibrated and cured.
4) According to the design requirements, the construction of the chimney barrel is carried out in sections, and the height of each section is generally about 2 meters. During construction, the pouring speed and height of concrete should be controlled to ensure the stability and construction quality of the sliding formwork. At the same time, the maintenance and maintenance of the template should be strengthened to prevent the template from being deformed or damaged. In the process of sliding form construction, safety monitoring and management should be strengthened to ensure construction safety and quality. During the construction process, the sliding form device should be regularly inspected and maintained to ensure its normal operation. At the same time, the management and coordination of the construction site should be strengthened to ensure the smooth progress of the construction. Through the implementation of the above measures, the efficiency and quality of chimney sliding form construction can be effectively improved, the construction period can be shortened, the cost can be reduced, and a solid foundation can be laid for the smooth operation of thermal power plants.
