Cement chimney is one of the common structures in industrial production, and its safety and stability are of great significance to the normal production of enterprises and the life safety of employees. However, due to various reasons, cement chimneys may experience cracking, which not only affects their service life, but can also cause harm to the surrounding environment and personnel. Therefore, it is essential for the repair work of cement chimney cracking. This article will introduce the causes, maintenance methods, and precautions of cement chimney cracking in detail.
Second, the cause of cement chimney cracking.
1.Unreasonable design: The chimney design does not fully consider the structural load, temperature change and other factors, resulting in insufficient structural strength and easy cracking.
2.Improper construction: The construction specifications are not strictly adhered to during the construction process, such as improper concrete mix ratio and untimely maintenance, etc., resulting in insufficient concrete strength and easy cracking.
3.Long-term use: During the long-term use of the chimney, it is affected by natural factors such as wind, sun, and rain, resulting in concrete aging and carbonization, resulting in cracking.
3. Cement chimney cracking maintenance method.
1.Surface treatment: First, the cracked area is surface treated to remove loose concrete and dust around the crack to expose the hard concrete base.
2.Grouting treatment: special grouting material is used to grout the cracks. Before grouting, the cracks should be closed, and then grouting should be carried out according to the specified pressure and speed. After the grouting is completed, it should be cured to ensure that the grouting material is fully cured.
3.Structural reinforcement: For severely cracked parts, structural reinforcement measures should be taken. The method of increasing reinforcement materials such as steel bars and steel plates can be used to improve the structural strength of the chimney.
4.Anti-corrosion treatment: Anti-corrosion treatment is carried out on the repaired chimney to prolong its service life. Methods such as brushing anticorrosive coatings and outsourcing anticorrosive layers can be used.
4. Precautions.
1.During the maintenance process, the safety of the construction personnel should be ensured and necessary protective measures should be taken.
2.Before maintenance, a comprehensive inspection and analysis of the chimney should be carried out to determine a reasonable maintenance plan.
3.During the maintenance process, the construction specifications and safety operation procedures should be strictly adhered to to ensure the quality of construction.
4.After the repair is completed, the chimney should be fully inspected and accepted to ensure its safety and stability.
V. Conclusions. The repair work of cement chimney cracking is of great significance to ensure the normal production of the enterprise and the life safety of employees. In the maintenance process, the cause of cracking should be fully understood, and reasonable maintenance methods and measures should be taken to ensure the quality and safety of maintenance. At the same time, the chimney should be inspected and maintained regularly for long-term use, and potential problems should be found and dealt with in time to ensure its safe and stable operation.
